Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Text Block)	NOTE 1–SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: HomeStreet, Inc. and its wholly owned subsidiaries (the “Company”) is a diversified financial services company serving customers primarily in the Pacific Northwest, California and Hawaii. The Company is principally engaged in real estate lending, including mortgage banking activities, and commercial and consumer banking. The consolidated financial statements include the accounts of HomeStreet, Inc. and its wholly owned subsidiaries, HomeStreet Capital Corporation and HomeStreet Bank (the “Bank”), and the Bank’s subsidiaries, HomeStreet/WMS, Inc., HomeStreet Reinsurance, Ltd., Continental Escrow Company and Union Street Holdings LLC. HomeStreet Bank was formed in 1986 and is a state-chartered commercial bank. The Company’s accounting and financial reporting policies conform to accounting principles generally accepted in the United States of America (U.S. GAAP). Inter-company balances and transactions have been eliminated in consolidation. In preparing the consolidated financial statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and revenues and expenses during the reporting periods and related disclosures. These estimates that require application of management's most difficult, subjective or complex judgments often result in the need to make estimates about the effect of matters that are inherently uncertain and may change in future periods. Management has made significant estimates in several areas, including the fair value of assets acquired and liabilities assumed in business combinations (Note 2, Business Combinations ), allowance for credit losses (Note 5, Loans and Credit Quality ), valuation of residential mortgage servicing rights and loans held for sale (Note 12, Mortgage Banking Operations ), loans held for investment (Note 5, Loans and Credit Quality ), investment securities (Note 4, Investment Securities ), derivatives (Note 11, Derivatives and Hedging Activities ), other real estate owned (Note 6, Other Real Estate Owned ), and taxes (Note 14, Income Taxes ). Actual results could differ materially from those estimates. Certain amounts in the financial statements from prior periods have been reclassified to conform to the current financial statement presentation. Consolidation The Company consolidates legal entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest by first evaluating whether an entity is a variable interest entity ("VIE"). If an entity is determined to not be a VIE, it is considered to be a voting interest entity. Variable Interest Entities The Company may have variable interests in VIEs arising from debt, equity or other monetary interests in an entity, which change with fluctuations in the fair value of the entity's assets. VIEs are entities that, by design, either (1) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (2) have equity investors that do not have the ability to make significant decisions relating to the entity's operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity. The primary beneficiary of a VIE (i.e., the party that has a controlling financial interest) is required to consolidate the assets and liabilities of the VIE. The primary beneficiary is the party that has both (1) the power to direct the activities of an entity that most significantly impact the VIE's economic performance; and (2) through its interests in the VIE, the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company's loans held for sale are sold predominantly to government-sponsored enterprises ("GSEs") Fannie Mae, Freddie Mac and Ginnie Mae for the purpose of securitization by the GSEs, who also provide credit enhancement of the loans through certain guarantee provisions. The Company typically retains the right to service the loans. Because of the power of the GSEs over the VIEs that hold the assets from these residential mortgage loan securitizations, the Company is not the primary beneficiary of the VIEs and therefore the VIEs are not consolidated. The Company performs on-going reassessments of: (1) whether entities previously evaluated under the majority voting-interest framework have become VIEs, based on certain events, and therefore become subject to the VIE consolidation framework; and (2) whether changes in the facts and circumstances regarding the Company's involvement with a VIE cause the Company's consolidation determination to change. Voting Interest Entities Voting interest entities are entities that have sufficient equity and provide the equity investors voting rights that enable them to make significant decisions relating to the entity's operations. For these types of entities, the Company's determination of whether it has a controlling financial interest is primarily based on the amount of voting equity interests held. Entities in which the Company has a controlling financial interest, through ownership of the majority of the entities' voting equity interests, or through other contractual rights that give the Company control, are consolidated by the Company. Investments in entities in which the Company has significant influence over operating and financing decisions (but does not own a majority of the voting equity interests) are accounted for in accordance with the equity method of accounting (which requires the Company to recognize its proportionate share of the entity's net earnings). These investments are generally included in other assets. The Company may have investments in limited partnerships or limited liability companies. The Company generally consolidates entities where it is the general partner or managing member. However, certain entities may provide limited partners or members with the ability to remove the Company as the general partner or managing member without cause (i.e., kick-out rights), based on a simple majority vote, or the limited partners or members have rights to participate in important decisions of the entity. Accordingly, the Company does not consolidate these entities, in which case they are accounted for in accordance with the equity method of accounting. For equity method investments holding real estate acquired in any manner for debts previously contracted with the Company, the investment is included in other real estate owned in the consolidated statements of financial condition and the proportionate share of the entity's net earnings are included in other real estate owned expense in the consolidated statements of operations. Cash and Cash Equivalents Cash and cash equivalents include cash, interest-earning overnight deposits at other financial institutions, and other investments with original maturities equal to three months or less. For the consolidated statements of cash flows, the Company considered cash equivalents to be investments that are readily convertible to known amounts, so near to their maturity that they present an insignificant risk of a change in fair value due to change in interest rates, and purchased in conjunction with cash management activities. Restricted cash of $2.4 million at both December 31, 2015 and 2014 is included in accounts receivable and other assets for reinsurance-related reserves. Investment Securities Investment securities that we might not hold until maturity are classified as available for sale ("AFS") and are reported at fair value in the statement of financial condition. Fair value measurement is based upon quoted market prices in active markets, if available. If quoted prices in active markets are not available, fair value is measured using pricing models or other model-based valuation techniques such as the present value of future cash flows, which consider prepayment assumptions and other factors such as credit losses and market liquidity. Unrealized gains and losses are excluded from earnings and reported, net of tax, in other comprehensive income (“OCI”). Purchase premiums and discounts are recognized in interest income using the effective interest method over the life of the securities. Purchase premiums or discounts related to mortgage-backed securities are amortized or accreted using projected prepayment speeds. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. AFS investment securities in unrealized loss positions are evaluated for other-than-temporary impairment (“OTTI”) at least quarterly. For AFS debt securities, a decline in fair value is considered to be other-than-temporary if the Company does not expect to recover the entire amortized cost basis of the security. For AFS equity securities, the Company considers a decline in fair value to be other-than-temporary if it is probable that the Company will not recover its amortized cost basis. Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of recoverability, all relevant information is considered, including the length of time and extent to which fair value has been less than the amortized cost basis, the cause of the price decline, credit performance of the issuer and underlying collateral, and recoveries or further declines in fair value subsequent to the balance sheet date. For debt securities, the Company measures and recognizes OTTI losses through earnings if (1) the Company has the intent to sell the security or (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. In these circumstances, the impairment loss is equal to the full difference between the amortized cost basis and the fair value of the security. For securities that are considered other-than-temporarily-impaired that the Company has the intent and ability to hold in an unrealized loss position, the OTTI write-down is separated into an amount representing the credit loss, which is recognized in earnings, and the amount related to other factors, which is recognized as a component of OCI. For equity securities, the Company recognizes OTTI losses through earnings if the Company intends to sell the security. The Company also considers other relevant factors, including its intent and ability to retain the security for a period of time sufficient to allow for any anticipated recovery in market value, and whether evidence exists to support a realizable value equal to or greater than the carrying value. Any impairment loss on an equity security is equal to the full difference between the amortized cost basis and the fair value of the security. Federal Home Loan Bank Stock As a borrower from the Federal Home Loan Bank of Des Moines and the Federal Home Loan Bank of San Francisco ("FHLB"), the Company is required to purchase an amount of FHLB stock based on our outstanding borrowings with the FHLB. This stock is used as collateral to secure the borrowings from the FHLB and is accounted for as a cost-method investment. FHLB stock is reviewed at least quarterly for possible OTTI, which includes an analysis of the FHLB's cash flows, capital needs and long-term viability. Loans Held for Sale Loans originated for sale in the secondary market, which is our principal market, or as whole loan sales are classified as loans held for sale. Management has elected the fair value option for all single family loans held for sale and records these loans at fair value. The fair value of loans held for sale is generally based on observable market prices from other loans in the secondary market that have similar collateral, credit, and interest rate characteristics. If quoted market prices are not readily available, the Company may consider other observable market data such as dealer quotes for similar loans or forward sale commitments. In certain cases, the fair value may be based on a discounted cash flow model. Gains and losses from changes in fair value on loans held for sale are recognized in net gain on mortgage loan origination and sale activities within noninterest income. Direct loan origination costs and fees for single family loans classified as held for sale are recognized in earnings. The change in fair value of loans held for sale is primarily driven by changes in interest rates subsequent to loan funding and changes in the fair value of related servicing asset, resulting in revaluation adjustments to the recorded fair value. The use of the fair value option allows the change in the fair value of loans to more effectively offset the change in the fair value of derivative instruments that are used as economic hedges to loans held for sale. Multifamily loans held for sale are accounted for at the lower of amortized cost or fair value. Related gains and losses are recognized in net gain on mortgage loan origination and sale activities. Direct loan origination costs and fees for multifamily loans classified as held for sale are deferred at origination and recognized in earnings at the time of sale. Loans Held for Investment Loans held for investment are reported at the principal amount outstanding, net of cumulative charge-offs, interest applied to principal (for loans accounted for using the cost recovery method), unamortized net deferred loan origination fees and costs and unamortized premiums or discounts on purchased loans. Deferred fees and costs and premiums and discounts are amortized over the contractual terms of the underlying loans using the constant effective yield (the interest method). Interest on loans is accrued and recognized as interest income at the contractual rate of interest. A determination is made as of the loan commitment date as to whether a loan will be held for sale or held for investment. This determination is based primarily on the type of loan or loan program and its related profitability characteristics. When a loan is designated as held for investment, the intent is to hold these loans for the foreseeable future or until maturity or pay-off. If subsequent changes occur, the Company may change its intent to hold these loans. Once a determination has been made to sell such loans, they are immediately transferred to loans held for sale and carried at the lower of cost or fair value. From time to time, the Company will originate loans to facilitate the sale of other real estate owned without a sufficient down payment from the borrower. Such loans are accounted for using the installment method and any gain on sale is deferred. Nonaccrual Loans Loans are placed on nonaccrual status when the full and timely collection of principal and interest is doubtful, generally when the loan becomes 90 days or more past due for principal or interest payment or if part of the principal balance has been charged off. All payments received on nonaccrual loans are accounted for using the cost recovery method. Under the cost recovery method, all cash collected is applied to first reduce the principal balance. A loan may be returned to accrual status if all delinquent principal and interest payments are brought current and the collectability of the remaining principal and interest payments in accordance with the loan agreement is reasonably assured. Loans that are well-secured and in the process of collection are maintained on accrual status, even if they are 90 days or more past due. Loans whose repayments are insured by the Federal Housing Administration ("FHA") or guaranteed by the Department of Veterans' Affairs ("VA") are maintained on accrual status even if 90 days or more past due. Impaired Loans A loan is considered impaired when it is probable that all contractual principal and interest payments due will not be collected in accordance with the terms of the loan agreement. Factors considered by management in determining whether a loan is impaired include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Troubled Debt Restructurings A loan is accounted for and reported as a troubled debt restructuring (“TDR”) when, for economic or legal reasons, we grant a concession to a borrower experiencing financial difficulty that we would not otherwise consider. A restructuring that results in only an insignificant delay in payment is not considered a concession. A delay may be considered insignificant if the payments subject to the delay are insignificant relative to the unpaid principal or collateral value and the contractual amount due, or the delay in timing of the restructured payment period is insignificant relative to the frequency of payments, the debt's original contractual maturity or original expected duration. TDRs are designated as impaired because interest and principal payments will not be received in accordance with original contract terms. TDRs that are performing and on accrual status as of the date of the modification remain on accrual status. TDRs that are nonperforming as of the date of modification generally remain as nonaccrual until the prospect of future payments in accordance with the modified loan agreement is reasonably assured, generally demonstrated when the borrower maintains compliance with the restructured terms for a predetermined period, normally at least six months. TDRs with temporary below-market concessions remain designated as a TDR and impaired regardless of the accrual or performance status until the loan is paid off. However, if the TDR loan has been modified in a subsequent restructure with market terms and the borrower is not currently experiencing financial difficulty, then the loan may be de-designated as a TDR. Allowance for Credit Losses Credit quality within the loans held for investment portfolio is continuously monitored by management and is reflected within the allowance for credit losses. The allowance for credit losses is maintained at a level that, in management's judgment, is appropriate to cover losses inherent within the Company’s loans held for investment portfolio, including unfunded credit commitments, as of the balance sheet date. The allowance for loan losses, as reported in our consolidated statements of financial condition, is adjusted by a provision for loan losses, which is recognized in earnings, and reduced by the charge-off of loan amounts, net of recoveries. The loss estimation process involves procedures to appropriately consider the unique characteristics of its two loan portfolio segments, the consumer loan portfolio segment and the commercial loan portfolio segment. These two segments are further disaggregated into loan classes, the level at which credit risk is monitored. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the overall loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses in those future periods. Credit quality is assessed and monitored by evaluating various attributes and utilizes such information in our evaluation of the adequacy of the allowance for credit losses. The following provides the credit quality indicators and risk elements that are most relevant and most carefully considered and monitored for each loan portfolio segment. Consumer Loan Portfolio Segment The consumer loan portfolio segment is comprised of the single family and home equity loan classes, which are underwritten after evaluating a borrower’s capacity, credit, and collateral. Capacity refers to a borrower’s ability to make payments on the loan. Several factors are considered when assessing a borrower’s capacity, including the borrower’s employment, income, current debt, assets, and level of equity in the property. Credit refers to how well a borrower manages their current and prior debts as documented by a credit report that provides credit scores and the borrower’s current and past information about their credit history. Collateral refers to the type and use of property, occupancy, and market value. Property appraisals are obtained to assist in evaluating collateral. Loan-to-property value and debt-to-income ratios, loan amount, and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect housing prices and demand and levels of unemployment. Commercial Loan Portfolio Segment The commercial loan portfolio segment is comprised of the commercial real estate, multifamily residential, construction/land development and commercial business loan classes, whose underwriting standards consider the factors described for single family and home equity loan classes as well as others when assessing the borrower’s and associated guarantors or other related party’s financial position. These other factors include assessing liquidity, the level and composition of net worth, leverage, considering all other lender amounts and position, an analysis of cash expected to flow through the obligors including the outflow to other lenders, and prior experience with the borrower. This information is used to assess adequate financial capacity, profitability, and experience. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity, and availability of long-term financing. Loan Loss Measurement Allowance levels are influenced by loan volumes, loan asset quality ratings ("AQR") migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as economic conditions. The methodology for evaluating the adequacy of the allowance for loan losses has two basic components: first, an asset-specific component involving the identification of impaired loans and the measurement of impairment for each individual loan identified; and second, a formula-based component for estimating probable loan principal losses for all other loans. Impaired Loans When a loan is identified as impaired, impairment is measured based on net realizable value, or the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the recorded investment balance of the loan. For impaired loans, we recognize impairment if we determine that the net realizable value of the impaired loan is less than the recorded investment of the loan (net of previous charge-offs and deferred loan fees and costs), except when the sole remaining source of collection is the underlying collateral. In these cases impairment is measured as the difference between the recorded investment balance of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. The starting point for determining the fair value of collateral is through obtaining external appraisals. Generally, collateral values for impaired loans are updated every twelve months, either from external third parties or in-house certified appraisers. A third party appraisal is required at least annually. Third party appraisals are obtained from a pre-approved list of independent, third party, local appraisal firms. Approval and addition to the list is based on experience, reputation, character, consistency and knowledge of the respective real estate market. Generally, appraisals are internally reviewed by the appraisal services group to ensure the quality of the appraisal and the expertise and independence of the appraiser. For performing consumer segment loans secured by real estate that are classified as collateral dependent, the Bank determines the fair value estimates semi-annually using automated valuation services. Once the impairment amount is determined an asset-specific allowance is provided for equal to the calculated impairment and included in the allowance for loan losses. If the calculated impairment is determined to be permanent or not recoverable, the impairment will be charged off. Factors considered by management in determining if impairment is permanent or not recoverable include whether management judges the loan to be uncollectible, repayment is deemed to be protracted beyond reasonable time frames or the loss becomes evident owing to the borrower’s lack of assets or, for single family loans, the loan is 180 days or more past due unless both well-secured and in the process of collection. Estimate of Probable Loan Losses In estimating the formula-based component of the allowance for loan losses, loans are segregated into loan classes. Loans are designated into loan classes based on loans pooled by product types and similar risk characteristics or areas of risk concentration. In determining the allowance for loan losses we derive an estimated credit loss assumption from a model that categorizes loan pools based on loan type and AQR or delinquency bucket. This model calculates an expected loss percentage for each loan category by considering the probability of default, based on the migration of loans from performing to loss by AQR or delinquency buckets using two-year analysis periods for commercial segments and one-year analysis periods for consumer segments, and the potential severity of loss, based on the aggregate net lifetime losses incurred per loan class. The formula-based component of the allowance for loan losses also considers qualitative factors for each loan class, including changes in the following: (1) lending policies and procedures; (2) international, national, regional and local economic business conditions and developments that affect the collectability of the portfolio, including the condition of various markets; (3) the nature and volume of the loan portfolio including the terms of the loans; (4) the experience, ability, and depth of the lending management and other relevant staff; (5) the volume and severity of past due and adversely classified or graded loans and the volume of nonaccrual loans; (6) the quality of our loan review system; (7) the value of underlying collateral for collateral-dependent loans. Additional factors include (8) the existence and effect of any concentrations of credit, and changes in the level of such concentrations and (9) the effect of external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio. Qualitative factors are expressed in basis points and are adjusted downward or upward based on management’s judgment as to the potential loss impact of each qualitative factor to a particular loan pool at the date of the analysis. Unfunded Loan Commitments The Company maintains a separate allowance for losses on unfunded loan commitments, which is included in accounts payable and other liabilities on the consolidated statements of financial condition. Management estimates the amount of probable losses by calculating a one-year commitment usage factor and applying the loss factors used in the allowance for loan loss methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan type. Other Real Estate Owned Other real estate owned ("OREO") represents real estate acquired for debts previously contracted with the Company, generally through the foreclosure of loans. In certain cases, such as foreclosures on loans involving both the Company and other participating lenders, other real estate owned may be held in the form of an investment in an unconsolidated legal entity that is in-substance real estate. These properties are initially recorded at the net realizable value (fair value of collateral less estimated costs to sell). Upon transfer of a loan to other real estate owned, an appraisal is obtained and any excess of the loan balance over the net realizable value is charged against the allowance for loan losses. The Company allows up to 90 days after foreclosure to finalize determination of net realizable value. Subsequent declines in net realizable value identified from the ongoing analysis of such properties are recognized in current period earnings within noninterest expense as a provision for losses on other real estate owned. The net realizable value of these assets is reviewed and updated at least every six months depending on the type of property, or more frequently as circumstances warrant. As part of our subsequent events analysis process, we review updated independent third-party appraisals received and internal collateral valuations received subsequent to the reporting period-end to determine whether the fair value of loan collateral or OREO has changed. Additionally, we review agreements to sell OREO properties executed prior to and subsequent to the reporting period-end to identify changes in the fair value of OREO properties. If we determine that current valuations have changed materially from the prior valuations, we record any additional loan impairments or adjustments to OREO carrying values as of the end of the prior reporting period. From time to time the Company may elect to accelerate the disposition of certain OREO properties in a time frame faster than the expected marketing period assumed in the appraisal supporting our valuation of such properties. At the time a property is identified and the decision to accelerate its disposition is made, that property’s underlying fair value is re-measured. Generally, to achieve an accelerated time frame in which to sell a property, the price that the Company is willing to accept for the disposition of the property decreases. Accordingly, the net realizable value of these properties is adjusted to reflect this change in valuation. Mortgage Servicing Rights We initially record all mortgage servicing rights ("MSRs") at fair value. For subsequent measurement of MSRs, accounting standards permit the election of either fair value or the lower of amortized cost or fair value. Management has elected to account for single family MSRs at fair value during the life of the MSR, with changes in fair value recorded through current period earnings. Fair value adjustments encompass market-driven valuation changes as well as modeled amortization involving the run-off of value that occurs due to the passage of time as individual loans are paid by borrowers. We account for multifamily MSRs at the lower of amortized cost or fair value. MSRs are recorded as separate assets on our consolidated statements of financial condition upon purchase of the rights or when we retain the right to service loans that we have sold. Net gains on mortgage loan origination and sale activities depend, in part, on the initial fair value of MSRs, which is based on a discounted cash flow model. Mortgage servicing income includes the changes in fair value over the reporting period of both our single family MSRs and the derivatives used to economically hedge our single family MSRs. Subsequent fair value measurements of single family MSRs, which are not traded in an active market with readily observable market prices, are determined by considering the present value of estimated future net servicing cash flows. Changes in the fair value of single family MSRs result from changes in (1) model inputs and assumptions and (2) modeled amortization, representing the collection and realization of expected cash flows and curtailments over time. The significant model inputs used to measure the fair value of single family MSRs include assumptions regarding market interest rates, projected prepayment speeds, discount rates, estimated costs of servicing and other income and additional expenses associated with the collection of delinquent loans. Market expectations about loan duration, and correspondingly the expected term of future servicing cash flows, may vary from time to time due to changes in expected prepayment activity, especially when interest rates rise or fall.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	NOTE 2–BUSINESS COMBINATIONS: Recent Acquisition Activity On February 1, 2016, the Company completed its acquisition of Orange County Business Bank ("OCBB") located in Irvine, California. Also on February 1, 2016, OCBB was merged with and into HomeStreet Bank. The purchase price of this acquisition was $55.9 million . OCBB shareholders as of the effective time received merger consideration equal to 0.5206 shares of HomeStreet common stock, and $1.1641 in cash upon the surrender of their OCBB shares, which resulted in the issuance of 2,459,486 shares of HomeStreet common stock. The primary objective for this acquisition is to grow our Commercial and Consumer Banking segment. Adding Orange County Business Bank’s branch brings HomeStreet’s Southern California retail deposit branch network to eight locations. On December 11, 2015, the Company acquired a former AmericanWest Bank retail deposit branch and certain related assets located in Dayton, Washington. This acquisition increases HomeStreet’s network of branches in eastern Washington to a total of five retail deposit branches. The Company purchased the branch from Banner Bank, which had recently acquired AmericanWest Bank. The purchase resulted in a bargain purchase gain of $381 thousand . Simplicity Acquisition On March 1, 2015, the Company completed its acquisition of Simplicity Bancorp, Inc., a Maryland corporation (“Simplicity”) and Simplicity’s wholly owned subsidiary, Simplicity Bank. Simplicity’s principal business activities prior to the merger were attracting retail deposits from the general public, originating or purchasing loans, primarily loans secured by first mortgages on owner-occupied, one-to-four family residences and multi-family residences located in Southern California and, to a lesser extent, commercial real estate, automobile and other consumer loans; and the origination and sale of fixed-rate, conforming, one-to-four family residential real estate loans in the secondary market, usually with servicing retained. The primary objective for this acquisition is to grow our Commercial and Consumer Banking segment by expanding the business of the former Simplicity branches by offering additional banking and lending products to former Simplicity customers as well as new customers. The acquisition was accomplished by the merger of Simplicity with and into HomeStreet, Inc. with HomeStreet, Inc. as the surviving corporation, followed by the merger of Simplicity Bank with and into HomeStreet Bank with HomeStreet Bank as the surviving subsidiary. The results of operations of Simplicity are included in the consolidated results of operations from the date of acquisition. At the closing, there were 7,180,005 shares of Simplicity common stock, par value $0.01, outstanding, all of which were cancelled and exchanged for an equal number of shares of HomeStreet common stock, no par value, issued to Simplicity’s stockholders. In connection with the merger, all outstanding options to purchase Simplicity common stock were cancelled in exchange for a cash payment equal to the difference between a calculated price of HomeStreet common stock and the exercise price of the option, provided, however, that any options that were out-of-the-money at the time of closing were cancelled for no consideration. The calculated price of $17.53 was determined by averaging the closing price of HomeStreet common stock for the 10 trading days prior to but not including the 5th business day before the closing date. The aggregate consideration paid by us in the Simplicity acquisition was approximately $471 thousand in cash and 7,180,005 shares of HomeStreet common stock with a fair value of approximately $124.2 million as of the acquisition date. We used current liquidity sources to fund the cash consideration. The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, Business Combinations . The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of acquisition date. The Company made significant estimates and exercised significant judgment in estimating the fair values and accounting for such acquired assets and assumed liabilities. A summary of the consideration paid, the assets acquired and liabilities assumed in the merger are presented below: (in thousands) March 1, 2015 Fair value consideration paid to Simplicity shareholders: Cash paid (79,399 stock options, consideration based on intrinsic value at a calculated price of $17.53) $ 471 Fair value of common shares issued (7,180,005 shares at $17.30 per share) 124,214 Total purchase price $ 124,685 Fair value of assets acquired: Cash and cash equivalents 112,667 Investment securities 26,845 Acquired loans 664,148 Mortgage servicing rights 980 Federal Home Loan Bank stock 5,520 Premises and equipment 2,966 Bank-owned life insurance 14,501 Core deposit intangibles 7,450 Accounts receivable and other assets 15,869 Total assets acquired 850,946 Fair value of liabilities assumed: Deposits 651,202 Federal Home Loan Bank advances 65,855 Accounts payable and accrued expenses 1,859 Total liabilities assumed 718,916 Net assets acquired $ 132,030 Bargain purchase (gain) $ (7,345 ) The application of the acquisition method of accounting resulted in a bargain purchase gain of $7.3 million which was reported as a component of noninterest income on our consolidated statements of operations. A substantial portion of the assets acquired from Simplicity were mortgage-related assets, which generally decrease in value as interest rates rise and increase in value as interest rates fall. The bargain purchase gain was driven largely by a substantial decline in long-term interest rates between the period shortly after our announcement of the Simplicity acquisition and its closing, which resulted in an increase in the fair value of the acquired mortgage assets and the overall net fair value of assets acquired. In addition, the Company believes it was able to acquire Simplicity for less than the fair value of its net assets due to Simplicity’s stock trading below its book value for an extended period of time prior to the announcement of the acquisition. The Company negotiated a purchase price per share for Simplicity that was above the prevailing stock price thereby representing a premium to the shareholders. The stock consideration transferred was based on a 1:1 stock conversion ratio. The price of the Company’s shares declined between the time the deal was announced and when it closed which also attributed to the bargain purchase gain. The acquisition of Simplicity by the Company was approved by Simplicity’s shareholders. For tax purposes, the bargain purchase gain is a non-taxable event. The operations of Simplicity are included in the Company's operating results as of the acquisition date of March 1, 2015 through the period ended December 31, 2015 . Acquisition-related costs were expensed as incurred in noninterest expense as merger and integration costs. The following table provides a breakout of Simplicity merger-related expense for the years ended December 31, 2015 and 2014 : Year Ended December 31, (in thousands) 2015 2014 Noninterest expense Salaries and related costs $ 7,669 $ 23 General and administrative 1,256 179 Legal 530 245 Consulting 5,539 388 Occupancy 335 4 Information services 481 50 Total noninterest expense $ 15,810 $ 889 The $664.1 million estimated fair value of loans acquired from Simplicity was determined by utilizing a discounted cash flow methodology considering credit and interest rate risk. Cash flows were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on the Company’s weighted average cost of capital. The discount for acquired loans from Simplicity was $16.6 million as of the acquisition date. A core deposit intangible (“CDI”) of $7.5 million was recognized related to the core deposits acquired from Simplicity. A discounted cash flow method was used to estimate the fair value of the certificates of deposit. The CDI is amortized over its estimated useful life of approximately ten years using an accelerated method and will be reviewed for impairment quarterly. The fair value of savings and transaction deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. A discounted cash flow method was used to estimate the fair value of the certificates of deposit. A premium, which will be amortized over the contractual life of the deposits, of $4.0 million was recorded for certificates of deposit. The fair value of Federal Home Loan Bank advances was estimated using a discounted cash flow method. A premium, which will be amortized over the contractual life of the advances, of $855 thousand was recorded for the Federal Home Loan Bank advances. The Company determined that the disclosure requirements related to the amounts of revenues and earnings of the acquiree included in the consolidated statements of operations since the acquisition date is impracticable. The financial activity and operating results of the acquiree were commingled with the Company’s financial activity and operating results as of the acquisition date. Unaudited Pro Forma Results of Operations The following table presents our unaudited pro forma results of operations for the periods presented as if the Simplicity acquisition had been completed on January 1, 2014. The unaudited pro forma results of operations include the historical accounts of Simplicity and pro forma adjustments as may be required, including the amortization of intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets acquired and liabilities assumed. The unaudited pro forma information is intended for informational purposes only and is not necessarily indicative of our future operating results or operating results that would have occurred had the Simplicity acquisition been completed at the beginning of 2014. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	NOTE 3–REGULATORY CAPITAL REQUIREMENTS: In July 2013, federal banking regulators (including the FDIC and the FRB) adopted new capital rules (the “Rules”). The Rules apply to both depository institutions (such as the Bank) and their holding companies (such as the Company). The Rules reflect, in part, certain standards initially adopted by the Basel Committee on Banking Supervision in December 2010 (which standards are commonly referred to as “Basel III”) as well as requirements contemplated by the Dodd-Frank Act. The Rules apply to both the Company and the Bank beginning in 2015. Failure to meet minimum capital requirements could initiate certain mandatory and possibly additional discretionary actions by the regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank and the Company must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank and the Company to maintain minimum amounts and ratios of common equity Tier 1 capital, Tier 1 leverage, Tier 1 risk-based capital and total risk-based capital (as defined in the regulations). The regulators also have the ability to impose elevated capital requirements in certain circumstances. At December 31, 2015 the Bank's capital ratios meet the regulatory capital category of “well capitalized” as defined by the Rules. The Bank’s and the Company's capital amounts and ratios under Basel III are included in the following table: At December 31, 2015 HomeStreet Bank Actual For Minimum Capital Adequacy Purposes To Be Categorized As “Well Capitalized” Under Prompt Corrective Action Provisions (in thousands) Amount Ratio Amount Ratio Amount Ratio Tier 1 leverage capital $ 455,101 9.46 % $ 192,428 4.0 % $ 240,536 5.0 % Common equity risk-based capital (to risk-weighted assets) 455,101 13.04 157,074 4.5 226,885 6.5 Tier 1 risk-based capital 455,101 13.04 209,432 6.0 279,243 8.0 Total risk-based capital $ 485,761 13.92 % $ 279,243 8.0 % $ 349,054 10.0 % At December 31, 2015 HomeStreet, Inc.

The decline in value is not related to any issuer- or industry-specific credit event. The Company has not identified any expected credit losses on its debt securities as of December 31, 2015 and 2014 . In addition, as of December 31, 2015 and 2014 , the Company had not made a decision to sell any of its debt securities held, nor did the Company consider it more likely than not that it would be required to sell such securities before recovery of their amortized cost basis. The following tables present the fair value of investment securities available for sale by contractual maturity along with the associated contractual yield for the periods indicated below. Contractual maturities for mortgage-backed securities and collateralized mortgage obligations as presented exclude the effect of expected prepayments. Expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations before the underlying mortgages mature. The weighted-average yield is computed using the contractual coupon of each security weighted based on the fair value of each security and does not include adjustments to a tax equivalent basis.

LOANS AND CREDIT QUALITY (Text Block)	NOTE 5–LOANS AND CREDIT QUALITY: For a detailed discussion of loans and credit quality, including accounting policies and the methodology used to estimate the allowance for credit losses, see Note 1, Summary of Significant Accounting Policies. The Company's portfolio of loans held for investment is divided into two portfolio segments, consumer loans and commercial loans, which are the same segments used to determine the allowance for loan losses. Within each portfolio segment, the Company monitors and assesses credit risk based on the risk characteristics of each of the following loan classes: single family and home equity and other loans within the consumer loan portfolio segment and commercial real estate, multifamily, construction/land development and commercial business loans within the commercial loan portfolio segment. Loans held for investment consist of the following: At December 31, (in thousands) 2015 2014 Consumer loans Single family $ 1,203,180 (1) $ 896,665 Home equity and other 256,373 135,598 1,459,553 1,032,263 Commercial loans Commercial real estate 600,703 523,464 Multifamily 426,557 55,088 Construction/land development 583,160 367,934 Commercial business 154,262 147,449 1,764,682 1,093,935 3,224,235 2,126,198 Net deferred loan fees and costs (2,237 ) (5,048 ) 3,221,998 2,121,150 Allowance for loan losses (29,278 ) (22,021 ) $ 3,192,720 $ 2,099,129 (1) Includes $21.5 million of loans where a fair value option election was made at the time of origination and, therefore, are carried at fair value with changes recognized in the consolidated statements of operations. Loans in the amount of $1.73 billion and $1.06 billion at December 31, 2015 and 2014 , respectively, were pledged to secure borrowings from the FHLB as part of our liquidity management strategy. Additionally, loans totaling $572.0 million and $487.2 million at December 31, 2015 and 2014 , respectively, were pledged to secure borrowings from the Federal Reserve Bank. The FHLB and Federal Reserve Bank do not have the right to sell or re-pledge these loans. It is the Company’s policy to make loans to officers, directors, and their associates in the ordinary course of business on substantially the same terms as those prevailing at the time for comparable transactions with other persons. The following is a summary of activity during the years ended December 31, 2015 and 2014 with respect to such aggregate loans to these related parties and their associates: Year Ended December 31, (in thousands) 2015 2014 Beginning balance, January 1 $ 5,500 $ 9,738 New loans 181 — Principal repayments and advances, net (1,170 ) (4,238 ) Ending balance, December 31 $ 4,511 $ 5,500 Credit Risk Concentrations Concentrations of credit risk arise when a number of customers are engaged in similar business activities or activities in the same geographic region, or when they have similar economic features that would cause their ability to meet contractual obligations to be similarly affected by changes in economic conditions. Loans held for investment are primarily secured by real estate located in the Pacific Northwest, California and Hawaii. At December 31, 2015 , we had concentrations representing 10% or more of the total portfolio by state and property type for the loan classes of single family, commercial real estate and construction/land development within the state of Washington, which represented 18.0% , 14.7% and 11.3% of the total portfolio, respectively. Additionally, we had a concentration representing 10% or more by state and property type for the single family loan class within the state of California, which represented 13.6% of the total portfolio. At December 31, 2014 we had concentrations representing 10% or more of the total portfolio by state and property type for the loan classes of single family, commercial real estate and construction/land development within the state of Washington, which represented 28.0% and 20.7% and 13.7% of the total portfolio, respectively. Credit Quality Management considers the level of allowance for loan losses to be appropriate to cover credit losses inherent within the loans held for investment portfolio as of December 31, 2015 . In addition to the allowance for loan losses, the Company maintains a separate allowance for losses related to unfunded loan commitments, and this amount is included in accounts payable and other liabilities on the consolidated statements of financial condition. Collectively, these allowances are referred to as the allowance for credit losses. For further information on the policies that govern the determination of the allowance for loan losses levels, see Note 1, Summary of Significant Accounting Policies.

We have five pass risk ratings which represent a level of credit quality that ranges from no well-defined deficiency or weakness to some noted weakness, however the risk of default on any loan classified as pass is expected to be remote. The five pass risk ratings are described below: Minimal Risk . A minimal risk loan, risk rated 1-Exceptional, is to a borrower of the highest quality. The borrower has an unquestioned ability to produce consistent profits and service all obligations and can absorb severe market disturbances with little or no difficulty. Low Risk. A low risk loan, risk rated 2-Superior, is similar in characteristics to a minimal risk loan. Balance sheet and operations are slightly more prone to fluctuations within the business cycle; however, debt capacity and debt service coverage remains strong. The borrower will have a strong demonstrated ability to produce profits and absorb market disturbances. Modest Risk. A modest risk loan, risk rated 3-Excellent, is a desirable loan with excellent sources of repayment and no currently identifiable risk associated with collection. The borrower exhibits a very strong capacity to repay the loan in accordance with the repayment agreement. The borrower may be susceptible to economic cycles, but will have cash reserves to weather these cycles. Average Risk. An average risk loan, risk rated 4-Good, is an attractive loan with sound sources of repayment and no material collection or repayment weakness evident. The borrower has an acceptable capacity to pay in accordance with the agreement. The borrower is susceptible to economic cycles and more efficient competition, but should have modest reserves sufficient to survive all but the most severe downturns or major setbacks. Acceptable Risk. An acceptable risk loan, risk rated 5-Acceptable, is a loan with lower than average, but still acceptable credit risk. These borrowers may have higher leverage, less certain but viable repayment sources, have limited financial reserves and may possess weaknesses that can be adequately mitigated through collateral, structural or credit enhancement. The borrower is susceptible to economic cycles and is less resilient to negative market forces or financial events. Reserves may be insufficient to survive a modest downturn. Watch. A watch loan, risk rated 6-Watch, is still pass-rated, but represents the lowest level of acceptable risk due to an emerging risk element or declining performance trend. Watch ratings are expected to be temporary, with issues resolved or manifested to the extent that a higher or lower rating would be appropriate. The borrower should have a plausible plan, with reasonable certainty of success, to correct the problems in a short period of time. Borrowers rated watch are characterized by elements of uncertainty, such as: • The borrower may be experiencing declining operating trends, strained cash flows or less-than anticipated performance. Cash flow should still be adequate to cover debt service, and the negative trends should be identified as being of a short-term or temporary nature. • The borrower may have experienced a minor, unexpected covenant violation. • Companies who may be experiencing tight working capital or have a cash cushion deficiency. • A loan may also be a watch if financial information is late, there is a documentation deficiency, the borrower has experienced unexpected management turnover, or if they face industry issues that, when combined with performance factors create uncertainty in their future ability to perform. • Delinquent payments, increasing and material overdraft activity, request for bulge and/or out- of-formula advances may be an indicator of inadequate working capital and may suggest a lower rating. • Failure of the intended repayment source to materialize as expected, or renewal of a loan (other than cash/marketable security secured or lines of credit) without reduction are possible indicators of a watch or worse risk rating. Special Mention. A special mention loan, risk rated 7-Special Mention, has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or the institutions credit position at some future date. They contain unfavorable characteristics and are generally undesirable. Loans in this category are currently protected but are potentially weak and constitute an undue and unwarranted credit risk, but not to the point of a substandard classification. A special mention loan has potential weaknesses, which if not checked or corrected, weaken the loan or inadequately protect the Company’s position at some future date. Such weaknesses include: • Performance is poor or significantly less than expected. There may be a temporary debt-servicing deficiency or inadequate working capital as evidenced by a cash cushion deficiency, but not to the extent that repayment is compromised. Material violation of financial covenants is common. • Loans with unresolved material issues that significantly cloud the debt service outlook, even though a debt servicing deficiency does not currently exist. • Modest underperformance or deviation from plan for real estate loans where absorption of rental/sales units is necessary to properly service the debt as structured. Depth of support for interest carry provided by owner/guarantors may mitigate and provide for improved rating. • This rating may be assigned when a loan officer is unable to supervise the credit properly, an inadequate loan agreement, an inability to control collateral, failure to obtain proper documentation, or any other deviation from prudent lending practices. • Unlike a substandard credit, there should be a reasonable expectation that these temporary issues will be corrected within the normal course of business, rather than liquidation of assets, and in a reasonable period of time. Substandard. A substandard loan, risk rated 8-Substandard, is inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the loan. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard loans, does not have to exist in individual loans classified substandard. Loans are classified as substandard when they have unsatisfactory characteristics causing unacceptable levels of risk. A substandard loan normally has one or more well-defined weaknesses that could jeopardize repayment of the loan. The likely need to liquidate assets to correct the problem, rather than repayment from successful operations is the key distinction between special mention and substandard. The following are examples of well-defined weaknesses: • Cash flow deficiencies or trends are of a magnitude to jeopardize current and future payments with no immediate relief. A loss is not presently expected, however the outlook is sufficiently uncertain to preclude ruling out the possibility. • The borrower has been unable to adjust to prolonged and unfavorable industry or economic trends. • Material underperformance or deviation from plan for real estate loans where absorption of rental/sales units is necessary to properly service the debt and risk is not mitigated by willingness and capacity of owner/guarantor to support interest payments. • Management character or honesty has become suspect. This includes instances where the borrower has become uncooperative. • Due to unprofitable or unsuccessful business operations, some form of restructuring of the business, including liquidation of assets, has become the primary source of loan repayment. Cash flow has deteriorated, or been diverted, to the point that sale of collateral is now the Company’s primary source of repayment (unless this was the original source of repayment). If the collateral is under the Company’s control and is cash or other liquid, highly marketable securities and properly margined, then a more appropriate rating might be special mention or watch. • The borrower is involved in bankruptcy proceedings where collateral liquidation values are expected to fully protect the Company against loss. • There is material, uncorrectable faulty documentation or materially suspect financial information. Doubtful. Loans classified as doubtful, risk rated 9-Doubtful, have all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work towards strengthening of the loan, classification as a loss (and immediate charge-off) is deferred until more exact status may be determined. Pending factors include proposed merger, acquisition, liquidation procedures, capital injection, and perfection of liens on additional collateral and refinancing plans. In certain circumstances, a doubtful rating will be temporary, while the Company is awaiting an updated collateral valuation. In these cases, once the collateral is valued and appropriate margin applied, the remaining un-collateralized portion will be charged-off. The remaining balance, properly margined, may then be upgraded to substandard, however must remain on non-accrual. Loss. Loans classified as loss, risk rated 10-Loss, are considered un-collectible and of such little value that the continuance as an active Company asset is not warranted. This rating does not mean that the loan has no recovery or salvage value, but rather that the loan should be charged-off now, even though partial or full recovery may be possible in the future. Impaired. Loans are classified as impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and interest when due, in accordance with the terms of the original loan agreement, without unreasonable delay. This generally includes all loans classified as nonaccrual and troubled debt restructurings. Impaired loans are risk rated for internal and regulatory rating purposes, but presented separately for clarification. Homogeneous loans maintain their original risk rating until they are greater than 30 days past due, and risk rating reclassification is based primarily on the past due status of the loan. The risk rating categories can be generally described by the following groupings for commercial and commercial real estate homogeneous loans: Watch. A homogeneous watch loan, risk rated 6, is 30-59 days past due from the required payment date at month-end. Special Mention. A homogeneous special mention loan, risk rated 7, is 60-89 days past due from the required payment date at month-end. S ubstandard. A homogeneous substandard loan, risk rated 8, is 90-179 days past due from the required payment date at month-end. Loss. A homogeneous loss loan, risk rated 10, is 180 days and more past due from the required payment date. These loans are generally charged-off in the month in which the 180 day time period elapses. The risk rating categories can be generally described by the following groupings for residential and home equity and other homogeneous loans: Watch. A homogeneous retail watch loan, risk rated 6, is 60-89 days past due from the required payment date at month-end. Substandard. A homogeneous retail substandard loan, risk rated 8, is 90-180 days past due from the required payment date at month-end. Loss. A homogeneous retail loss loan, risk rated 10, becomes past due 180 cumulative days from the contractual due date. These loans are generally charged-off in the month in which the 180 day period elapses. Residential and home equity loans modified in a troubled debt restructure are not considered homogeneous. The risk rating classification for such loans are based on the non-homogeneous definitions noted above. The following tables summarize designated loan grades by loan portfolio segment and loan class.

Nonaccrual and Past Due Loans Loans are placed on nonaccrual status when the full and timely collection of principal and interest is doubtful, generally when the loan becomes 90 days or more past due for principal or interest payment or if part of the principal balance has been charged off. Loans whose repayments are insured by the FHA or guaranteed by the VA are generally maintained on accrual status even if 90 days or more past due.

Federal Home Loan Bank and Other Borrowings [Text Block]	NOTE 9–FEDERAL HOME LOAN BANK AND OTHER BORROWINGS: Federal Home Loan Bank The Company borrows funds through advances from the FHLB. FHLB advances totaled $1.02 billion and $597.6 million as of December 31, 2015 , and 2014 , respectively. Weighted-average interest rates on the advances were 0.64% , 0.41% , and 0.43% at December 31, 2015 , 2014 and 2013 , respectively. The advances may be collateralized by stock in the FHLB, pledged securities, and unencumbered qualifying loans. The Company has an available line of credit with the FHLB equal to 35.0% of assets, subject to collateralization requirements. Based on the amount of qualifying collateral available, borrowing capacity from the FHLB was $320.4 million as of December 31, 2015 . The FHLB is not contractually bound to continue to offer credit to the Company, and the Company’s access to credit from this agency for future borrowings may be discontinued at any time.

As of December 31, 2015 and 2014 , the Company held $44.3 million and $33.9 million , respectively, of FHLB stock. FHLB stock is carried at par value and is restricted to transactions between the FHLB and its member institutions. FHLB stock can only be purchased or redeemed at par value. Both cash and dividends received on FHLB stock are reported in earnings. Management periodically evaluates FHLB stock for other-than-temporary impairment. Management’s determination of whether these investments are impaired is based on its assessment of ultimate recoverability of par value rather than recognizing temporary declines in value. The determination of whether the decline affects the ultimate recoverability is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLB; and (4) the liquidity position of the FHLB. Based on this evaluation, the Company determined there is not an other-than-temporary impairment of the FHLB stock investment as of December 31, 2015 , or 2014 . Federal Reserve Bank of San Francisco The Company may also borrow on a collateralized basis from the Federal Reserve Bank of San Francisco (“FRBSF”). At December 31, 2015 and 2014 , there were no outstanding borrowings from the FRBSF. Based on the amount of qualifying collateral available, borrowing capacity from the FRBSF was $382.1 million at December 31, 2015 . The FRBSF is not contractually bound to offer credit to the Company, and the Company’s access to credit from this agency for future borrowings may be discontinued at any time. Federal Funds Purchased and Securities Sold Under Agreements to Repurchase Federal funds transactions involve lending reserve balances on a short-term basis. Securities borrowed or purchased under agreements to resell are collateralized lending transactions utilized to accommodate customer transactions, earn interest rate spreads, and obtain securities for settlement and for collateral. At December 31, 2015 , we had no balance of federal funds purchased and securities sold under agreements to repurchase. At December 31, 2014 , we had $50.0 million in federal funds purchased and no balance of securities sold under agreements to repurchase.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	NOTE 11–DERIVATIVES AND HEDGING ACTIVITIES: To reduce the risk of significant interest rate fluctuations on the value of certain assets and liabilities, such as certain mortgage loans held for sale or MSRs, the Company utilizes derivatives, such as forward sale commitments, futures, option contracts, interest rate swaps and swaptions as risk management instruments in its hedging strategy. Derivative transactions are measured in terms of notional amount, which is not recorded in the consolidated statements of financial condition. The notional amount is generally not exchanged and is used as the basis for interest and other contractual payments. The use of derivatives as interest rate risk management instruments helps minimize significant, unplanned fluctuations in earnings, fair value of assets and liabilities, and cash flows caused by interest rate volatility. This approach involves mitigating the repricing characteristics of certain assets or liabilities so that changes in interest rates do not have a significant adverse effect on net interest margin and cash flows. As a result of interest rate fluctuations, hedged assets and liabilities will gain or lose market value. In a fair value hedging strategy, the effect of this gain or loss will generally be offset by the gain or loss on the derivatives linked to hedged assets or liabilities. In a cash flow hedging strategy, management manages the variability of cash payments due to interest rate fluctuations by the effective use of derivatives linked to hedged assets and liabilities. We held no derivatives designated as a fair value, cash flow or foreign currency hedge instrument at December 31, 2015 or 2014 . Derivatives are reported at their respective fair values in the other assets or accounts payable and other liabilities line items on the consolidated statements of financial condition, with changes in fair value reflected in current period earnings. As permitted under U.S. GAAP, the Company nets derivative assets and liabilities when a legally enforceable master netting agreement exists between the Company and the derivative counterparty, which are documented under industry standard master agreements and credit support annexes. The Company's master netting agreements provide that following an uncured payment default or other event of default the non-defaulting party may promptly terminate all transactions between the parties and determine a net amount due to be paid to, or by, the defaulting party. An event of default may also occur under a credit support annex if a party fails to make a collateral delivery (which remains uncured following applicable notice and grace periods). The Company's right of offset requires that master netting agreements are legally enforceable and that the exercise of rights by the non-defaulting party under these agreements will not be stayed, or avoided under applicable law upon an event of default including bankruptcy, insolvency or similar proceeding. The collateral used under the Company's master netting agreements is typically cash, but securities may be used under agreements with certain counterparties. Receivables related to cash collateral that has been paid to counterparties is included in other assets on the Company's consolidated statements of financial condition. Any securities pledged to counterparties as collateral remain on the consolidated statement of financial condition. Refer to Note 4, Investment Securities for further information on securities collateral pledged. At December 31, 2015 and 2014 , the Company did not hold any collateral received from counterparties under derivative transactions. The Company’s derivative activities are monitored by the asset/liability management committee. The treasury function, which includes asset/liability management, is responsible for hedging strategies developed through analysis of data from financial models and other internal and industry sources. The resulting hedging strategies are incorporated into the overall risk management strategies. For further information on the policies that govern derivative and hedging activities, see Note 1, Summary of Significant Accounting Policies . The notional amounts and fair values for derivatives consist of the following.

These amounts were not netted against the derivative receivables and payables, because, at an individual counterparty level, the collateral exceeded the fair value exposure at December 31, 2014 . Free-standing derivatives are used for fair value interest rate risk management purposes and do not qualify for hedge accounting treatment, referred to as economic hedges. Economic hedges are used to hedge against adverse changes in fair value of single family mortgage servicing rights (“single family MSRs”), interest rate lock commitments (“IRLCs”) for single family mortgage loans that the Company intends to sell, and single family mortgage loans held for sale. Free-standing derivatives used as economic hedges for single family MSRs typically include positions in interest rate futures, options on 10-year treasury contracts, forward sales commitments on mortgage-backed securities, and interest rate swap and swaption contracts. The single family MSRs and the free-standing derivatives are carried at fair value with changes in fair value included in mortgage servicing income. The free-standing derivatives used as economic hedges for IRLCs and single family mortgage loans held for sale are forward sales commitments on mortgage-backed securities and option contracts. IRLCs, single family mortgage loans held for sale, and the free-standing derivatives (“economic hedges”) are carried at fair value with changes in fair value included in net gain on mortgage loan origination and sale activities. The following table presents the net gain (loss) recognized on derivatives, including economic hedge derivatives, within the respective line items in the statement of operations for the periods indicated.

(2) Includes $4.6 million in pre-tax gain during 2014 from the sale of loans that were originally held for investment. The Company’s portfolio of loans serviced for others is primarily comprised of loans held in U.S. government and agency MBS issued by Fannie Mae, Freddie Mac and Ginnie Mae. Loans serviced for others are not included in the consolidated statements of financial condition as they are not assets of the Company. The composition of loans serviced for others is presented below at the unpaid principal balance.

The Company may be required to repurchase mortgage loans or indemnify loan purchasers due to defects in the origination process of the loan, such as documentation errors, underwriting errors and judgments, appraisal errors, early payment defaults and fraud. For further information on the Company's mortgage repurchase liability, see Note 13, Commitments, Guarantees and Contingencies. The following is a summary of changes in the Company's liability for estimated mortgage repurchase losses. Year Ended December 31, (in thousands) 2015 2014 Balance, beginning of period $ 1,956 $ 1,260 Additions (1) 2,764 1,430 Realized losses (2) (1,798 ) (734 ) Balance, end of period $ 2,922 $ 1,956 (1) Includes additions for new loan sales and changes in estimated probable future repurchase losses on previously sold loans. (2) Includes principal losses and accrued interest on repurchased loans, “make-whole” settlements, settlements with claimants and certain related expense. Advances are made to Ginnie Mae mortgage pools for delinquent loan payments. We also fund foreclosure costs and we repurchase loans from Ginnie Mae mortgage pools prior to recovery of guaranteed amounts. Ginnie Mae advances of $9.6 million and $7.8 million were recorded in other assets as of December 31, 2015 and 2014 , respectively. When the Company has the unilateral right to repurchase Ginnie Mae pool loans it has previously sold (generally loans that are more than 90 days past due), the Company then records the loan on its consolidated statement of financial condition. At December 31, 2015 and 2014 , delinquent or defaulted mortgage loans currently in Ginnie Mae pools that the Company has recognized on its consolidated statements of financial condition totaled $29.0 million and $21.2 million , respectively, with a corresponding amount recorded within accounts payable and other liabilities on the consolidated statements of financial condition. The recognition of previously sold loans does not impact the accounting for the previously recognized MSRs. Revenue from mortgage servicing, including the effects of derivative risk management instruments, consisted of the following. Year Ended December 31, (in thousands) 2015 2014 2013 Servicing income, net: Servicing fees and other $ 42,197 $ 37,818 $ 34,173 Changes in fair value of single family MSRs due to modeled amortization (1) (34,038 ) (26,112 ) (24,321 ) Amortization of multifamily MSRs (1,992 ) (1,712 ) (1,803 ) 6,167 9,994 8,049 Risk management, single family MSRs: Changes in fair value due to changes in model inputs and/or assumptions (2) 6,555 (15,629 ) $ 29,456 Net gain from derivatives economically hedging MSR 11,709 39,727 (20,432 ) 18,264 24,098 9,024 Mortgage servicing income $ 24,431 $ 34,092 $ 17,073 (1) Represents changes due to collection/realization of expected cash flows and curtailments. (2) Principally reflects changes in model assumptions, including prepayment speed assumptions, which are primarily affected by changes in mortgage interest rates. All MSRs are initially measured and recorded at fair value at the time loans are sold. Single family MSRs are subsequently carried at fair value with changes in fair value reflected in earnings in the periods in which the changes occur, while multifamily MSRs are subsequently carried at the lower of amortized cost or fair value. The fair value of MSRs is determined based on the price that would be received to sell the MSRs in an orderly transaction between market participants at the measurement date. The Company determines fair value using a valuation model that calculates the net present value of estimated future cash flows. Estimates of future cash flows include contractual servicing fees, ancillary income and costs of servicing, the timing of which are impacted by assumptions, primarily expected prepayment speeds and discount rates, which relate to the underlying performance of the loans. The initial fair value measurement of MSRs is adjusted up or down depending on whether the underlying loan pool interest rate is at a premium, discount or par. Key economic assumptions used in measuring the initial fair value of capitalized single family MSRs were as follows. Year Ended December 31, (rates per annum) (1) 2015 2014 2013 Constant prepayment rate ("CPR") (2) 14.95 % 13.30 % 9.28 % Discount rate (3) 10.29 % 10.50 % 10.25 % (1) Weighted average rates for sales during the period for sales of loans with similar characteristics. (2) Represents the expected lifetime average. (3) Discount rate is a rate based on market observations. Key economic assumptions and the sensitivity of the current fair value for single family MSRs to immediate adverse changes in those assumptions were as follows. (dollars in thousands) At December 31, 2015 Fair value of single family MSR $ 156,604 Expected weighted-average life (in years) 5.21 Constant prepayment rate (1) 15.30 % Impact on 25 basis points adverse change $ (12,130 ) Impact on 50 basis points adverse change $ (25,352 ) Discount rate 10.50 % Impact on fair value of 100 basis points increase $ (4,939 ) Impact on fair value of 200 basis points increase $ (9,519 ) (1) Represents the expected lifetime average. These sensitivities are hypothetical and subject to key assumptions of the underlying valuation model. As the table above demonstrates, the Company’s methodology for estimating the fair value of MSRs is highly sensitive to changes in key assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may provide an incentive to refinance; however, this may also indicate a slowing economy and an increase in the unemployment rate, which reduces the number of borrowers who qualify for refinancing), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made as of a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. The changes in single family MSRs measured at fair value are as follows. Year Ended December 31, (in thousands) 2015 2014 2013 Beginning balance $ 112,439 $ 153,128 $ 87,396 Additions and amortization: Originations 70,659 43,231 60,576 Purchases 989 19 21 Sale of single family MSRs — (43,248 ) — Changes due to modeled amortization (1) (34,038 ) (26,112 ) (24,321 ) Net additions and amortization 37,610 (26,110 ) 36,276 Changes in fair value due to changes in model inputs and/or assumptions (2) 6,555 (14,579 ) 29,456 Ending balance $ 156,604 $ 112,439 $ 153,128 (1) Represents changes due to collection/realization of expected cash flows and curtailments. (2) Principally reflects changes in model assumptions, including prepayment speed assumptions, which are primarily affected by changes in mortgage interest rates. MSRs resulting from the sale of multifamily loans are recorded at fair value and subsequently carried at the lower of amortized cost or fair value. Multifamily MSRs are amortized in proportion to, and over, the estimated period the net servicing income will be collected. The changes in multifamily MSRs measured at the lower of amortized cost or fair value were as follows. Year Ended December 31, (in thousands) 2015 2014 2013 Beginning balance $ 10,885 $ 9,335 $ 8,097 Origination 5,758 3,260 3,027 Amortization (1,992 ) (1,710 ) (1,789 ) Ending balance $ 14,651 $ 10,885 $ 9,335 At December 31, 2015 , the expected weighted-average life of the Company’s multifamily MSRs was 9.83 years . Projected amortization expense for the gross carrying value of multifamily MSRs is estimated as follows. (in thousands) At December 31, 2015 2016 $ 2,208 2017 2,086 2018 1,930 2019 1,823 2020 1,691 2021 and thereafter 4,913 Carrying value of multifamily MSR $ 14,651 The projected amortization expense of multifamily MSRs is an estimate and subject to key assumptions of the underlying valuation model. The amortization expense for future periods was calculated by applying the same quantitative factors, such as actual MSR prepayment experience and discount rates, which were used to determine amortization expense. These factors are inherently subject to significant fluctuations, primarily due to the effect that changes in interest rates may have on expected loan prepayment experience. Accordingly, any projection of MSR amortization in future periods is limited by the conditions that existed at the time the calculations were performed and may not be indicative of actual amortization expense that will be recorded in future periods.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, GUARANTEES, AND CONTINGENCIES	NOTE 13–COMMITMENTS, GUARANTEES AND CONTINGENCIES: Commitments Commitments to extend credit are agreements to lend to customers in accordance with predetermined contractual provisions. These commitments may be for specific periods or contain termination clauses and may require the payment of a fee by the borrower. The total amount of unused commitments do not necessarily represent future credit exposure or cash requirements in that commitments may expire without being drawn upon. The Company makes certain unfunded loan commitments as part of its lending activities that have not been recognized in the Company’s financial statements. These include commitments to extend credit made as part of the Company's lending activities on loans the Company intends to hold in its loans held for investment portfolio. The aggregate amount of these unrecognized unfunded loan commitments existing at December 31, 2015 and 2014 was $52.9 million and $72.0 million , respectively. In the ordinary course of business, the Company extends secured and unsecured open-end loans to meet the financing needs of its customers. Undistributed construction loan commitments, where the Company has an obligation to advance funds for construction progress payments, were $456.4 million and $379.4 million at December 31, 2015 and 2014 , respectively. Unused home equity and commercial banking funding lines totaled $216.5 million and $149.4 million at December 31, 2015 and 2014 , respectively. The Company has recorded an allowance for credit losses on loan commitments, included in accounts payable and other liabilities on the consolidated statements of financial condition, of $1.4 million and $503 thousand at December 31, 2015 and 2014 , respectively. The Company is obligated under non-cancelable leases for office space. Generally, the office leases also contain five-year renewal and space options. Rental expense under non-cancelable operating leases totaled $20.1 million , $15.3 million , and $11.4 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. Minimum rental payments for all non-cancelable leases were as follows. (in thousands) At December 31, 2015 2016 $ 19,486 2017 18,987 2018 17,328 2019 14,530 2020 12,071 2021 and thereafter 55,073 $ 137,475 Guarantees In the ordinary course of business, the Company sells loans through the Fannie Mae Multifamily Delegated Underwriting and Servicing Program (“DUS" ® ) that are subject to a credit loss sharing arrangement. The Company services the loans for Fannie Mae and shares in the risk of loss with Fannie Mae under the terms of the DUS contracts. Under the program, the DUS lender is contractually responsible for the first 5% of losses and then shares in the remainder of losses with Fannie Mae with a maximum lender loss of 20% of the original principal balance of each DUS loan. For loans that have been sold through this program, a liability is recorded for this loss sharing arrangement under the accounting guidance for guarantees. As of December 31, 2015 and 2014 , the total unpaid principal balance of loans sold under this program was $924.4 million and $752.6 million , respectively. The Company’s reserve liability related to this arrangement totaled $3.0 million and $2.3 million at December 31, 2015 and 2014 , respectively. There were no actual losses incurred under this arrangement during the years ended December 31, 2015 , 2014 and 2013. Mortgage repurchase liability In the ordinary course of business, the Company sells residential mortgage loans to GSEs and other entities. In addition, the Company pools FHA-insured and VA-guaranteed mortgage loans into Ginnie Mae, Fannie Mae and Freddie Mac guaranteed mortgage-backed securities. The Company has made representations and warranties that the loans sold meet certain requirements. The Company may be required to repurchase mortgage loans or indemnify loan purchasers due to defects in the origination process of the loan, such as documentation errors, underwriting errors and judgments, early payment defaults and fraud. These obligations expose the Company to mark-to-market and credit losses on the repurchased mortgage loans after accounting for any mortgage insurance that we may receive. Generally, the maximum amount of future payments the Company would be required to make for breaches of these representations and warranties would be equal to the unpaid principal balance of such loans that are deemed to have defects that were sold to purchasers plus, in certain circumstances, accrued and unpaid interest on such loans and certain expenses. The Company does not typically receive repurchase requests from the FHA or VA. As an originator of FHA-insured or VA-guaranteed loans, the Company is responsible for obtaining the insurance with FHA or the guarantee with the VA. If loans are later found not to meet the requirements of FHA or VA, through required internal quality control reviews or through agency audits, the Company may be required to indemnify FHA or VA against losses. The loans remain in Ginnie Mae pools unless and until they are repurchased by the Company. In general, once an FHA or VA loan becomes 90 days past due, the Company repurchases the FHA or VA residential mortgage loan to minimize the cost of interest advances on the loan. If the loan is cured through borrower efforts or through loss mitigation activities, the loan may be resold into a Ginnie Mae pool. The Company's liability for mortgage loan repurchase losses incorporates probable losses associated with such indemnification. The total unpaid principal balance of loans sold on a servicing-retained basis that were subject to the terms and conditions of these representations and warranties totaled $15.43 billion and $11.30 billion as of December 31, 2015 and 2014 , respectively. At December 31, 2015 and 2014 , the Company had recorded a mortgage repurchase liability for loans sold on a servicing-retained and servicing-released basis, included in accounts payable and other liabilities on the consolidated statements of financial condition, of $2.9 million and $2.0 million , respectively. Contingencies In the normal course of business, the Company may have various legal claims and other similar contingent matters outstanding for which a loss may be realized. For these claims, the Company establishes a liability for contingent losses when it is probable that a loss has been incurred and the amount of loss can be reasonably estimated. For claims determined to be reasonably possible but not probable of resulting in a loss, there may be a range of possible losses in excess of the established liability. At December 31, 2015 , we reviewed our legal claims and determined that there were no material claims that were considered to be probable or reasonably possible of resulting in a loss. As a result, the Company did not have any material amounts reserved for legal claims as of December 31, 2015 .

The tax effect of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities consisted of the following: At December 31, (in thousands) 2015 2014 Deferred tax assets: Provision for loan losses $ 15,843 $ 11,890 Federal and state net operating loss carryforwards 4,979 10,044 Section 382 built-in loss limitation — 5,291 Other real estate owned 656 468 Accrued liabilities 3,524 2,199 Other investments 319 330 Leases 1,976 1,153 Unrealized loss on investment securities available for sale 1,304 — Tax credits 1,178 3,358 Stock options 999 902 Loan valuation 5,752 497 Other, net 2,753 236 39,283 36,368 Valuation allowance — — 39,283 36,368 Deferred tax liabilities: Mortgage servicing rights (48,540 ) (34,030 ) Unrealized gain on investment securities available for sale — (252 ) FHLB dividends (190 ) (4,348 ) Deferred loan fees and costs (2,108 ) (1,943 ) Premises and equipment (5,282 ) (1,865 ) Other intangibles - core deposit intangible (2,829 ) (700 ) Other, net (190 ) (242 ) (59,139 ) (43,380 ) Net deferred tax liability $ (19,856 ) $ (7,012 ) The Company currently has a net deferred tax liability. This net deferred tax liability is included in accounts payable and other liabilities on the consolidated statements of financial condition. As a consequence of our initial public offering (IPO) in February 2012 and subsequent acquisitions, the Company is subject to the limitation of Section 382 of the Internal Revenue Code of 1986, as amended, and similar state tax provisions. Section 382 limits the Company’s annual utilization of net operating losses and other tax attributes incurred prior to the change of control against post-change income. Specifically, the Company is subject to annual limitations on the amounts of net operating loss and credit carryover that the Company can use from its pre-IPO period, or from the pre-acquisition periods of Yakima National Bank, Fortune Bank and Simplicity Bancorp. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. As of December 31, 2015 management determined that sufficient evidence exists to support the future utilization of all of the Company’s deferred tax assets. At December 31, 2015 , the Company has federal net operating loss carryforwards totaling $13.9 million , which expire between 2029 and 2033 . In addition, as of December 31, 2015 , the Company has an alternative minimum tax credit of $1.2 million that may be carried forward indefinitely. The Company also has state net operating loss carryforwards of $1.7 million that expire between 2016 and 2030 . Retained earnings at December 31, 2015 and 2014 include approximately $12.7 million in tax basis bad debt reserves for which no income tax liability has been recorded. This represents the balance of bad debt reserves created for tax purposes as of December 31, 1987. These amounts are subject to recapture (i.e., included in taxable income) in certain events, such as in the event HomeStreet Bank ceases to be a bank. In the event of recapture, the Company will incur a federal tax liability on this pre-1988 bad debt reserve balance at the then prevailing corporate tax rate, which tax liability is estimated at $4.4 million as of December 31, 2015 . The Company has recorded unrecognized tax benefits (including potential interest of $19 thousand ) of $438 thousand as of December 31, 2015 . There were no unrecognized tax benefits at December 31, 2014 . The Company does not expect the uncertainty related to its unrecognized tax benefits to be resolved within the next twelve months. A reconciliation of our unrecognized tax benefits, excluding accrued interest and penalties, for the years ended December 31, 2015 , 2014 and 2013 is as follows: Year Ended December 31, (in thousands) 2015 2014 2013 Balance, beginning of year $ — $ — $ — Increases related to prior year tax positions 419 — — Decreases related to prior year tax positions — — — Income taxes at statutory rate — — — Settlements — — — Lapse of statute — — — Balance, end of year $ 419 $ — $ — The Company files Federal income tax returns with the Internal Revenue Service and state income tax returns with various state tax authorities.

Share Based Compensation Plans [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	NOTE 16–SHARE-BASED COMPENSATION PLANS: For the years ended December 31, 2015 , 2014 , and 2013 , the Company recognized $1.1 million , $1.5 million , and $1.1 million of compensation cost, respectively, for share-based compensation awards. 2014 Equity Incentive Plan In May 2014, the shareholders approved the Company's 2014 Equity Incentive Plan (the “2014 EIP”). Under the 2014 EIP, all of the Company’s officers, employees, directors and/or consultants are eligible to receive awards. Awards which may be granted under the 2014 EIP include incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, unrestricted stock, performance share awards and performance compensation awards. The maximum amount of HomeStreet, Inc. common stock available for grant under the 2014 EIP is 900,000 shares, which includes shares of common stock that were still available for issuance under the 2010 Plan and the 2011 Plan. Nonqualified Stock Options The Company grants nonqualified options to key senior management personnel. A summary of changes in nonqualified stock options granted for the year ended December 31, 2015 is as follows: Number Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (2) (in thousands) Options outstanding at December 31, 2014 601,024 $ 12.16 7.2 years $ 3,329 Granted — — 0.0 years — Cancelled or forfeited (15,136 ) 20.71 7.4 years 16 Exercised (44,971 ) 15.42 6.4 years 285 Options outstanding at December 31, 2015 540,917 11.65 6.2 years 5,443 Options that are exercisable and expected to be exercisable (1) 540,900 11.65 6.2 years 5,443 Options exercisable 540,043 $ 11.63 6.2 years $ 5,443 (1) Adjusted for estimated forfeitures. (2) Intrinsic value is the amount by which fair value of the underlying stock exceeds the exercise price. Under this plan, 44,971 options have been exercised during the year ended December 31, 2015 , resulting in cash received and related income tax benefits totaling $693 thousand . As of December 31, 2015 , there was $2 thousand of total unrecognized compensation costs related to stock options. Compensation costs are recognized over the requisite service period, which typically is the vesting period. Unrecognized compensation costs are expected to be recognized over the remaining weighted-average requisite service period of four months . As observable market prices are generally not available for estimating the fair value of stock options, an option-pricing model is utilized to estimate fair value. The fair value of the options granted during 2013 was estimated as of the grant date using a Black-Scholes Merton (“Black-Scholes”) model and the assumptions noted in the following table. There were no options granted during the year ended December 31, 2015 and 2014 . Year Ended December 31, 2013 Weighted-average fair value per share $ 8.78 Expected term of the option 6 years Expected stock price volatility 50.04 % Annual risk-free interest rate 1.18 % Expected annual dividend yield 2.03 % The weighted-average expected term of 6 years used to value option awards issued in 2013 was an estimate based on an expectation that the holders of the stock options, once vested, will exercise them – ultimately reflecting the settlement of all vested options. As the Company did not have historical exercise behavior to reference for these types of options, the Company leveraged the “simplified” method for estimating the expected term of these “plain vanilla” stock options. When estimating expected volatility and the dividend yield, the Company considered historical data of other similar entities that were publicly traded over a period commensurate with the life of the options. A single median was derived for each input from this population. Restricted Shares The Company grants restricted shares to key senior management personnel and directors. A summary of the status of restricted shares follows. Number Weighted Average Grant Date Fair Value Restricted shares outstanding at December 31, 2014 118,517 $ 18.26 Granted 107,507 18.41 Cancelled or forfeited (40,179 ) 18.63 Vested (26,636 ) 17.33 Restricted shares outstanding at December 31, 2015 159,209 18.42 Nonvested at December 31, 2015 159,209 $ 18.42 At December 31, 2015 , there was $1.8 million of total unrecognized compensation cost related to nonvested restricted shares. Unrecognized compensation cost is generally expected to be recognized over a weighted average period of 1.9 years . Restricted share awards granted to senior management vest based upon the achievement of certain market conditions. One-third vested when the 30-day rolling average share price exceeded 25% of the grant date fair value; one-third vested when the 30-day rolling average share price exceeded 40% of the grant date fair value; and one-third vested when the 30-day rolling average share price exceeded 50% of the grant date fair value. The Company accrues compensation expense based upon an estimate of the awards' expected vesting period. If a market condition is satisfied prior to the end of the estimated vesting period any unrecognized compensation costs associated with the portion of restricted shares that vested earlier than expected are immediately recognized in earnings. Certain restricted stock awards granted to senior management during 2015 and 2014 contain both service conditions and performance conditions. Restricted stock units (“RSUs”) are stock awards with a pro-rata three year vesting, and the fair market value of the awards are determined at the grant date. Performance share units ("PSUs") are stock awards where the number of shares ultimately received by the employee depends on the company’s performance against specified targets and vest over a three-year period. The fair value of each PSU is determined on the grant date, based on the company’s stock price, and assumes that performance targets will be achieved. Over the performance period, the number of shares of stock that will be issued is adjusted upward or downward based upon the probability of achievement of performance targets. The ultimate number of shares issued and the related compensation cost recognized as expense will be based on a comparison of the final performance metrics to the specified targets. Compensation cost is recognized over the requisite three-year service period on a straight-line basis and adjusted for changes in the probability that the performance targets will be achieved.

Fair Value Measurement

Fair Value Measurement	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	NOTE 17–FAIR VALUE MEASUREMENT: The term "fair value" is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The Company’s approach is to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. Fair Value Hierarchy A three-level valuation hierarchy has been established under ASC 820 for disclosure of fair value measurements. The valuation hierarchy is based on the observability of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels are defined as follows: • Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. An active market for the asset or liability is a market in which transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. This includes quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability for substantially the full term of the financial instrument. • Level 3 – Unobservable inputs for the asset or liability. These inputs reflect the Company’s assumptions of what market participants would use in pricing the asset or liability. The Company's policy regarding transfers between levels of the fair value hierarchy is that all transfers are assumed to occur at the end of the reporting period. Valuation Processes The Company has various processes and controls in place to ensure that fair value measurements are reasonably estimated. The Finance Committee of the Board provides oversight and approves the Company’s Asset/Liability Management Policy ("ALMP"). The Company's ALMP governs, among other things, the application and control of the valuation models used to measure fair value. On a quarterly basis, the Company’s Asset/Liability Management Committee ("ALCO") and the Finance Committee of the Board review significant modeling variables used to measure the fair value of the Company’s financial instruments, including the significant inputs used in the valuation of single family MSRs. Additionally, ALCO periodically obtains an independent review of the MSR valuation process and procedures, including a review of the model architecture and the valuation assumptions. The Company obtains an MSR valuation from an independent valuation firm monthly to assist with the validation of the fair value estimate and the reasonableness of the assumptions used in measuring fair value. The Company’s real estate valuations are overseen by the Company’s appraisal department, which is independent of the Company’s lending and credit administration functions. The appraisal department maintains the Company’s appraisal policy and recommends changes to the policy subject to approval by the Company’s Loan Committee and the Credit Committee of the Board. The Company’s appraisals are prepared by independent third-party appraisers and the Company’s internal appraisers. Single family appraisals are generally reviewed by the Company’s single family loan underwriters. Single family appraisals with unusual, higher risk or complex characteristics, as well as commercial real estate appraisals, are reviewed by the Company’s appraisal department. We obtain pricing from third party service providers for determining the fair value of a substantial portion of our investment securities available for sale. We have processes in place to evaluate such third party pricing services to ensure information obtained and valuation techniques used are appropriate. For fair value measurements obtained from third party services, we monitor and review the results to ensure the values are reasonable and in line with market experience for similar classes of securities. While the inputs used by the pricing vendor in determining fair value are not provided, and therefore unavailable for our review, we do perform certain procedures to validate the values received, including comparisons to other sources of valuation (if available), comparisons to other independent market data and a variance analysis of prices by Company personnel that are not responsible for the performance of the investment securities. Estimation of Fair Value Fair value is based on quoted market prices, when available. In cases where a quoted price for an asset or liability is not available, the Company uses valuation models to estimate fair value. These models incorporate inputs such as forward yield curves, loan prepayment assumptions, expected loss assumptions, market volatilities, and pricing spreads utilizing market-based inputs where readily available. The Company believes its valuation methods are appropriate and consistent with those that would be used by other market participants. However, imprecision in estimating unobservable inputs and other factors may result in these fair value measurements not reflecting the amount realized in an actual sale or transfer of the asset or liability in a current market exchange. The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions, and classification of the Company’s assets and liabilities. Asset/Liability class Valuation methodology, inputs and assumptions Classification Cash and cash equivalents Carrying value is a reasonable estimate of fair value based on the short-term nature of the instruments. Estimated fair value classified as Level 1. Investment securities Investment securities available for sale Observable market prices of identical or similar securities are used where available. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 2 recurring fair value measurement Investment securities held to maturity Observable market prices of identical or similar securities are used where available. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Carried at amortized cost. Loans held for sale Single family loans, excluding loans transferred from held for investment Fair value is based on observable market data, including: • Quoted market prices, where available • Dealer quotes for similar loans • Forward sale commitments Level 2 recurring fair value measurement When not derived from observable market inputs, fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Estimated fair value classified as Level 3. Loans originated as held for investment and transferred to held for sale Fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Carried at lower of amortized cost or fair value. Multifamily loans (DUS) The sale price is set at the time the loan commitment is made, and as such subsequent changes in market conditions have a very limited effect, if any, on the value of these loans carried on the consolidated statements of financial condition, which are typically sold within 30 days of origination. Carried at lower of amortized cost or fair value. Estimated fair value classified as Level 2.

Loans held for investment, collateral dependent Fair value is based on appraised value of collateral, which considers sales comparison and income approach methodologies. Adjustments are made for various factors, which may include: • Adjustments for variations in specific property qualities such as location, physical dissimilarities, market conditions at the time of sale, income producing characteristics and other factors Carried at lower of amortized cost or fair value of collateral, less the estimated cost to sell. Loans held for investment transferred from loans held for sale Fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 3 recurring fair value measurement Mortgage servicing rights Single family MSRs For information on how the Company measures the fair value of its single family MSRs, including key economic assumptions and the sensitivity of fair value to changes in those assumptions, see Note 12 , Mortgage Banking Operations .

Level 3 Recurring Fair Value Measurements The Company's level 3 recurring fair value measurements consist of single family mortgage servicing rights, single family loans held for investment where fair value option was elected, certain single family loans held for sale, and interest rate lock commitments, which are accounted for as derivatives. For information regarding fair value changes and activity for single family MSRs during the years ended December 31, 2015 and 2014 , see Note 12, Mortgage Banking Operations . The fair value of IRLCs considers several factors including the fair value in the secondary market of the underlying loan resulting from the exercise of the commitment, the expected net future cash flows related to the associated servicing of the loan (referred to as the value of servicing) and the probability that the commitment will not be converted into a funded loan (referred to as a fall-out factor). The fair value of IRLCs on loans held for sale, while based on interest rates observable in the market, is highly dependent on the ultimate closing of the loans. The significance of the fall-out factor to the fair value measurement of an individual IRLC is generally highest at the time that the rate lock is initiated and declines as closing procedures are performed and the underlying loan gets closer to funding. The fall-out factor applied is based on historical experience. The value of servicing is impacted by a variety of factors, including prepayment assumptions, discount rates, delinquency rates, contractually specified servicing fees, servicing costs, and underlying portfolio characteristics. Because these inputs are not observable in market trades, the fall-out factor and value of servicing are considered to be level 3 inputs. The fair value of IRLCs decreases in value upon an increase in the fall-out factor and increases in value upon an increase in the value of servicing. Changes in the fall-out factor and value of servicing do not increase or decrease based on movements in other significant unobservable inputs. The Company recognizes unrealized gains and losses from the time that an IRLC is initiated until the gain or loss is realized at the time the loan closes, which generally occurs within 30-90 days. For IRLCs that fall out, any unrealized gain or loss is reversed, which generally occurs at the end of the commitment period. The gains and losses recognized on IRLC derivatives generally correlates to volume of single family interest rate lock commitments made during the reporting period (after adjusting for estimated fallout) while the amount of unrealized gains and losses realized at settlement generally correlates to the volume of single family closed loans during the reporting period. The Company uses the discounted cash flow model to estimate the fair value of certain loans that have been transferred from held for sale to held for investment and single family loans held for sale when the fair value of the loans is not derived using observable market inputs. The key assumption in the valuation model is the implied spread to benchmark interest rate curve. The implied spread is not directly observable in the market and is derived from third party pricing which is based on market information from comparable loan pools. The fair value estimate of these certain single family loans that have been transferred from held for sale to held for investment and these certain single family loans held for sale is sensitive to changes in the benchmark interest rate which might result in a significantly higher or lower fair value measurement. During the first quarter of 2015, the Company transferred certain loans from held for sale to held for investment. These loans were originated as held for sale loans where the Company has elected fair value option. The Company determined these loans to be level 3 recurring assets as the valuation technique included a significant unobservable input. The total amount of held for investment loans where fair value option election was made was $21.5 million at December 31, 2015 . The following information presents significant Level 3 unobservable inputs used to measure fair value of single family loans held for investment where fair value option was elected.

These assets include certain loans held for investment and other real estate owned that are carried at the lower of cost or fair value of the underlying collateral, less the estimated cost to sell. The estimated fair values of real estate collateral are generally based on internal evaluations and appraisals of such collateral, which use the market approach and income approach methodologies. All impaired loans are subject to an internal evaluation completed quarterly by management as part of the allowance process. The fair value of commercial properties are generally based on third-party appraisals that consider recent sales of comparable properties, including their income-generating characteristics, adjusted (generally based on unobservable inputs) to reflect the general assumptions that a market participant would make when analyzing the property for purchase. The Company uses a fair value of collateral technique to apply adjustments to the appraisal value of certain commercial loans held for investment that are collateralized by real estate. During the years ended December 31, 2015 and 2014 , the Company recorded no adjustments to the appraisal values of certain commercial loans held for investment that are collateralized by real estate. The Company uses a fair value of collateral technique to apply adjustments to the stated value of certain commercial loans held for investment that are not collateralized by real estate. During the year ended December 31, 2015 , the Company applied a range of stated value adjustments of 0.0% to 100.0% , with a weighted average of 36.3% . During the year ended December 31, 2014 , the Company applied a range of stated value adjustments of 10.0% to 100.0% , with a weighted average of 41.8% . During the years ended December 31, 2015 and 2014 , the Company did not apply any adjustment to the appraisal value of OREO. Residential properties are generally based on unadjusted third-party appraisals. Factors considered in determining the fair value include geographic sales trends, the value of comparable surrounding properties as well as the condition of the property. These adjustments include management assumptions that are based on the type of collateral dependent loan and may increase or decrease an appraised value. Management adjustments vary significantly depending on the location, physical characteristics and income producing potential of each individual property. The quality and volume of market information available at the time of the appraisal can vary from period-to-period and cause significant changes to the nature and magnitude of the unobservable inputs used. Given these variations, changes in these unobservable inputs are generally not a reliable indicator for how fair value will increase or decrease from period to period. The following tables present assets that had changes in their recorded fair value during the years ended December 31, 2015 and 2014 and still held at the end of the respective reporting period.

Segment Reporting [Abstract]
OPERATING SEGMENTS	NOTE 19–BUSINESS SEGMENTS: The Company's business segments are determined based on the products and services provided, as well as the nature of the related business activities, and they reflect the manner in which financial information is currently evaluated by management. The Company organizes the segments into two lines of business: Commercial and Consumer Banking segment and Mortgage Banking segment. A description of the Company's business segments and the products and services that they provide is as follows. Commercial and Consumer Banking provides diversified financial products and services to our commercial and consumer customers through bank branches and through ATMs, online, mobile and telephone banking. These products and services include deposit products; residential, consumer, business and agricultural portfolio loans; non-deposit investment products; insurance products and cash management services. We originate construction loans, bridge loans and permanent loans for our portfolio primarily on single family residences, and on office, retail, industrial and multifamily property types. We originate multifamily real estate loans through our Fannie Mae DUS business, whereby loans are sold to or securitized by Fannie Mae, while the Company generally retains the servicing rights. This segment is also responsible for the management of the Company's portfolio of investment securities. Mortgage Banking originates single family residential mortgage loans for sale in the secondary markets. The majority of our mortgage loans are sold to or securitized by Fannie Mae, Freddie Mac or Ginnie Mae, while we retain the right to service these loans. We have become a rated originator and servicer of jumbo loans, allowing us to sell these loans to other securitizers. Additionally, we purchase loans from WMS Series LLC through a correspondent arrangement with that company. We also sell loans on a servicing-released and servicing-retained basis to securitizers and correspondent lenders. A small percentage of our loans are brokered to other lenders or sold on a servicing-released basis to correspondent lenders. On occasion, we may sell a portion of our MSR portfolio.We manage the loan funding and the interest rate risk associated with the secondary market loan sales and the retained single family mortgage servicing rights within this business segment. We use various management accounting methodologies to assign certain income statement items to the responsible operating segment, including: • a funds transfer pricing (“FTP”) system, which allocates interest income credits and funding charges between the segments, assigning to each segment a funding credit for its liabilities, such as deposits, and a charge to fund its assets; • an allocation of charges for services rendered to the segments by centralized functions, such as corporate overhead, which are generally based on each segment’s consumption patterns; and • an allocation of the Company's consolidated income taxes which are based on the effective tax rate applied to the segment's pretax income or loss. The FTP methodology is based on external market factors and aligns the expected weighted-average life of the financial asset or liability to external economic data, such as the U.S. Dollar LIBOR/Swap curve, and provides a consistent basis for determining the cost of funds to be allocated to each operating segment. Financial highlights by operating segment were as follows.

Interest earned includes actual interest earned on segment assets and, if the segment has excess liabilities, interest credits for providing funding to the other segment. The cost of liabilities includes interest expense on segment liabilities and, if the segment does not have enough liabilities to fund its assets, a funding charge based on the cost of excess liabilities from another segment.

Summary of Significant Accoun33

Summary of Significant Accounting Policies Summary of significant accounting (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Consolidation The Company consolidates legal entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest by first evaluating whether an entity is a variable interest entity ("VIE"). If an entity is determined to not be a VIE, it is considered to be a voting interest entity. Variable Interest Entities The Company may have variable interests in VIEs arising from debt, equity or other monetary interests in an entity, which change with fluctuations in the fair value of the entity's assets. VIEs are entities that, by design, either (1) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (2) have equity investors that do not have the ability to make significant decisions relating to the entity's operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity. The primary beneficiary of a VIE (i.e., the party that has a controlling financial interest) is required to consolidate the assets and liabilities of the VIE. The primary beneficiary is the party that has both (1) the power to direct the activities of an entity that most significantly impact the VIE's economic performance; and (2) through its interests in the VIE, the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company's loans held for sale are sold predominantly to government-sponsored enterprises ("GSEs") Fannie Mae, Freddie Mac and Ginnie Mae for the purpose of securitization by the GSEs, who also provide credit enhancement of the loans through certain guarantee provisions. The Company typically retains the right to service the loans. Because of the power of the GSEs over the VIEs that hold the assets from these residential mortgage loan securitizations, the Company is not the primary beneficiary of the VIEs and therefore the VIEs are not consolidated. The Company performs on-going reassessments of: (1) whether entities previously evaluated under the majority voting-interest framework have become VIEs, based on certain events, and therefore become subject to the VIE consolidation framework; and (2) whether changes in the facts and circumstances regarding the Company's involvement with a VIE cause the Company's consolidation determination to change. Voting Interest Entities Voting interest entities are entities that have sufficient equity and provide the equity investors voting rights that enable them to make significant decisions relating to the entity's operations. For these types of entities, the Company's determination of whether it has a controlling financial interest is primarily based on the amount of voting equity interests held. Entities in which the Company has a controlling financial interest, through ownership of the majority of the entities' voting equity interests, or through other contractual rights that give the Company control, are consolidated by the Company. Investments in entities in which the Company has significant influence over operating and financing decisions (but does not own a majority of the voting equity interests) are accounted for in accordance with the equity method of accounting (which requires the Company to recognize its proportionate share of the entity's net earnings). These investments are generally included in other assets. The Company may have investments in limited partnerships or limited liability companies. The Company generally consolidates entities where it is the general partner or managing member. However, certain entities may provide limited partners or members with the ability to remove the Company as the general partner or managing member without cause (i.e., kick-out rights), based on a simple majority vote, or the limited partners or members have rights to participate in important decisions of the entity. Accordingly, the Company does not consolidate these entities, in which case they are accounted for in accordance with the equity method of accounting. For equity method investments holding real estate acquired in any manner for debts previously contracted with the Company, the investment is included in other real estate owned in the consolidated statements of financial condition and the proportionate share of the entity's net earnings are included in other real estate owned expense in the consolidated statements of operations.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents include cash, interest-earning overnight deposits at other financial institutions, and other investments with original maturities equal to three months or less. For the consolidated statements of cash flows, the Company considered cash equivalents to be investments that are readily convertible to known amounts, so near to their maturity that they present an insignificant risk of a change in fair value due to change in interest rates, and purchased in conjunction with cash management activities. Restricted cash of $2.4 million at both December 31, 2015 and 2014 is included in accounts receivable and other assets for reinsurance-related reserves.
Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]	Investment Securities Investment securities that we might not hold until maturity are classified as available for sale ("AFS") and are reported at fair value in the statement of financial condition. Fair value measurement is based upon quoted market prices in active markets, if available. If quoted prices in active markets are not available, fair value is measured using pricing models or other model-based valuation techniques such as the present value of future cash flows, which consider prepayment assumptions and other factors such as credit losses and market liquidity. Unrealized gains and losses are excluded from earnings and reported, net of tax, in other comprehensive income (“OCI”). Purchase premiums and discounts are recognized in interest income using the effective interest method over the life of the securities. Purchase premiums or discounts related to mortgage-backed securities are amortized or accreted using projected prepayment speeds. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. AFS investment securities in unrealized loss positions are evaluated for other-than-temporary impairment (“OTTI”) at least quarterly. For AFS debt securities, a decline in fair value is considered to be other-than-temporary if the Company does not expect to recover the entire amortized cost basis of the security. For AFS equity securities, the Company considers a decline in fair value to be other-than-temporary if it is probable that the Company will not recover its amortized cost basis. Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of recoverability, all relevant information is considered, including the length of time and extent to which fair value has been less than the amortized cost basis, the cause of the price decline, credit performance of the issuer and underlying collateral, and recoveries or further declines in fair value subsequent to the balance sheet date. For debt securities, the Company measures and recognizes OTTI losses through earnings if (1) the Company has the intent to sell the security or (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. In these circumstances, the impairment loss is equal to the full difference between the amortized cost basis and the fair value of the security. For securities that are considered other-than-temporarily-impaired that the Company has the intent and ability to hold in an unrealized loss position, the OTTI write-down is separated into an amount representing the credit loss, which is recognized in earnings, and the amount related to other factors, which is recognized as a component of OCI. For equity securities, the Company recognizes OTTI losses through earnings if the Company intends to sell the security. The Company also considers other relevant factors, including its intent and ability to retain the security for a period of time sufficient to allow for any anticipated recovery in market value, and whether evidence exists to support a realizable value equal to or greater than the carrying value. Any impairment loss on an equity security is equal to the full difference between the amortized cost basis and the fair value of the security.
Real Estate Owned, Valuation Allowance, Policy [Policy Text Block]	Other Real Estate Owned Other real estate owned ("OREO") represents real estate acquired for debts previously contracted with the Company, generally through the foreclosure of loans. In certain cases, such as foreclosures on loans involving both the Company and other participating lenders, other real estate owned may be held in the form of an investment in an unconsolidated legal entity that is in-substance real estate. These properties are initially recorded at the net realizable value (fair value of collateral less estimated costs to sell). Upon transfer of a loan to other real estate owned, an appraisal is obtained and any excess of the loan balance over the net realizable value is charged against the allowance for loan losses. The Company allows up to 90 days after foreclosure to finalize determination of net realizable value. Subsequent declines in net realizable value identified from the ongoing analysis of such properties are recognized in current period earnings within noninterest expense as a provision for losses on other real estate owned. The net realizable value of these assets is reviewed and updated at least every six months depending on the type of property, or more frequently as circumstances warrant. As part of our subsequent events analysis process, we review updated independent third-party appraisals received and internal collateral valuations received subsequent to the reporting period-end to determine whether the fair value of loan collateral or OREO has changed. Additionally, we review agreements to sell OREO properties executed prior to and subsequent to the reporting period-end to identify changes in the fair value of OREO properties. If we determine that current valuations have changed materially from the prior valuations, we record any additional loan impairments or adjustments to OREO carrying values as of the end of the prior reporting period. From time to time the Company may elect to accelerate the disposition of certain OREO properties in a time frame faster than the expected marketing period assumed in the appraisal supporting our valuation of such properties. At the time a property is identified and the decision to accelerate its disposition is made, that property’s underlying fair value is re-measured. Generally, to achieve an accelerated time frame in which to sell a property, the price that the Company is willing to accept for the disposition of the property decreases. Accordingly, the net realizable value of these properties is adjusted to reflect this change in valuation.
Equity Method Investments, Policy [Policy Text Block]	Investment in WMS Series LLC HomeStreet/WMS, Inc. (Windermere Mortgage Services, Inc.), a wholly owned and consolidated subsidiary of the Bank, has an affiliated business arrangement with Windermere Real Estate, WMS Series Limited Liability Company ("WMS LLC"). The Company and Windermere Real Estate each have 50% joint control over the governance of WMS LLC. The operations of WMS LLC, which is subdivided into 30 individual operating series, are recorded using the equity method of accounting. The Company recognizes its proportionate share of the results of operations of WMS LLC as income from WMS Series LLC in noninterest income within the Company's consolidated statements of operations. The Company has determined that WMS LLC is not a VIE and further does not consolidate WMS LLC under the voting interest model. The 30 individual operating series, which are divisions of WMS LLC that are allocated assets and liabilities and allow certain forms of legal isolation, are not considered to be stand-alone subsidiary legal entities for purposes of applying the consolidation guidance under U.S. GAAP. As a result, the 30 individual operating series are not considered to be VIEs based on the determination that WMS LLC is not a VIE. The investment is reviewed for possible other-than-temporary impairment annually, or more frequently if warranted. The review typically includes an analysis of facts and circumstances of the investment and expectations regarding the investment’s future cash flows. The Company has not recorded other-than-temporary impairment on this investment. Equity method investment income from WMS LLC was $2.5 million , $1.3 million , and $1.7 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. The Company’s investment in WMS LLC was $2.9 million and $3.1 million , which is included in accounts receivable and other assets at December 31, 2015 and 2014 , respectively. The Company provides contracted services to WMS LLC related to accounting, loan shipping, loan underwriting, quality control, secondary marketing, and information systems support performed by Company employees on behalf of WMS LLC. The Company recorded contracted services income/(loss) of $(960) thousand , $(1.2) million , and $(951) thousand for the years ended December 31, 2015 , 2014 and 2013 , respectively. Income related to WMS LLC, including equity method investment income and contracted services, is classified as income from WMS Series LLC in noninterest income within the consolidated statements of operations. The Company purchased $616.9 million , $491.3 million and $695.7 million of single family mortgage loans from WMS LLC for the years ended December 31, 2015 , 2014 and 2013 , respectively. The Company provides a $25.0 million secured line of credit that allows WMS LLC to fund and close single family mortgage loans in the name of WMS LLC. The outstanding balance of the secured line of credit was $8.6 million and $7.1 million at December 31, 2015 , and 2014 , respectively. The highest outstanding balance of the secured line of credit was $13.4 million and $12.4 million during 2015 and 2014 , respectively. The line of credit matures July 1, 2016 .
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Furniture and equipment and leasehold improvements are stated at cost less accumulated depreciation or amortization and depreciated or amortized over the shorter of the useful life of the related asset or the term of the lease, generally 3 to 15 years, using the straight-line method. Management periodically evaluates furniture and equipment and leasehold improvements for impairment.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill Goodwill is recorded upon completion of a business combination as the difference between the purchase price and the fair value of net identifiable assets acquired. Subsequent to initial recognition, the Company tests goodwill for impairment during the third quarter of each fiscal year, or more often if events or circumstances, such as adverse changes in the business climate, indicate there may be impairment. Goodwill was not impaired at December 31, 2015 or 2014 , nor was any goodwill written off due to impairment during 2015 , 2014 or 2013 .
Debt, Policy [Policy Text Block]	Trust Preferred Securities Trust preferred securities allow investors the ability to invest in junior subordinated debentures of the Company, which provide the Company with long-term financing. The transaction begins with the formation of a VIE established as a trust by the Company. This trust issues two classes of securities: common securities, all of which are purchased and held by the Company and recorded in other assets on the consolidated statements of financial position, and trust preferred securities, which are sold to third-party investors. The trust holds subordinated debentures (debt) issued by the Company, which the Company records in long-term debt on the consolidated statement of financial position. The trust finances the purchase the subordinated debentures with the proceeds from the sale of its common and preferred securities. The junior subordinated debentures are the sole assets of the trust, and the coupon rate on the debt mirrors the dividend payment on the preferred security. The Company also has the right to defer interest payments for up to five years and has the right to call the preferred securities. These preferred securities are non-voting and do not have the right to convert to shares of the issuer. The trust's common equity securities issued to the Company are not considered to be equity at risk because the equity securities were financed by the trust through the purchase of the debentures from the Company. As a consequence, the Company holds no variable interest in the trust, and therefore, is not the trust's primary beneficiary.
Repurchase and Resale Agreements Policy [Policy Text Block]	Federal Funds Purchased and Securities Sold Under Agreements to Repurchase From time to time, the Company may enter into federal funds transactions involving purchasing reserve balances on a short-term basis, or sales of securities under agreements to repurchase the same securities (“repurchase agreements”). Repurchase agreements are accounted for as secured financing arrangements with the obligation to repurchase securities sold reflected as a liability in the consolidated statements of financial condition. The dollar amount of securities underlying the repurchase agreements remains in investment securities available for sale. For short-term instruments, including securities sold under agreements to repurchase and federal funds purchased, the carrying amount is a reasonable estimate of the fair value.
Income Tax, Policy [Policy Text Block]	Income Taxes Our income tax expense, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. We are subject to federal income tax and also state income taxes in a number of different states. Significant judgments and estimates are required in determining the consolidated income tax expense. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. Changes in tax laws and rates may affect recorded deferred tax assets and liabilities and our effective tax rate in the future. Such changes are accounted for in the period of enactment, and are reflected as discrete tax items in the Company’s tax provision. The Company records net deferred tax assets to the extent it is believed that these assets will more likely than not be realized. In making this determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. After reviewing and weighing all of the positive and negative evidence, if the positive evidence outweighs the negative evidence, then the Company does not record a valuation allowance for deferred tax assets. If the negative evidence outweighs the positive evidence, then a valuation allowance for all or a portion of the deferred tax assets is recorded. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in different jurisdictions. Accounting Standards Codification ("ASC") 740 states that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. We record unrecognized tax benefits as liabilities in accordance with ASC 740 (including any potential interest and penalties) and we adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available.
Derivatives, Policy [Policy Text Block]	Derivatives and Hedging Activities In order to reduce the risk of significant interest rate fluctuations on the value of certain assets and liabilities, such as certain mortgage loans held for sale or mortgage servicing rights, the Company utilizes derivatives, such as forward sale commitments, interest rate futures, option contracts, interest rate swaps and swaptions as risk management instruments in its hedging strategy. All free-standing derivatives are required to be recorded on the consolidated statements of financial condition at fair value. As permitted under U.S. GAAP, the Company nets derivative assets and liabilities, and related collateral, when a legally enforceable master netting agreement exists between the Company and the derivative counterparty. The accounting for changes in fair value of a derivative depends on whether or not the transaction has been designated and qualifies for hedge accounting. Derivatives that are not designated as hedges are reported and measured at fair value through earnings. The Company does not use derivatives for trading purposes. Before initiating a position where hedge accounting treatment is desired, the Company formally documents the relationship between the hedging instrument(s) and the hedged item(s), as well as its risk management objective and strategy. For derivative instruments qualifying for hedge accounting treatment, the instrument is designed as either: (1) a hedge of changes in fair value of a recognized asset or liability or of an unrecognized firm commitment (a fair value hedge), or (2) a hedge of the variability in expected future cash flows associated with an existing recognized asset or liability or a probable forecasted transaction (a cash flow hedge). Derivatives where the Company has not attempted to achieve or attempted but did not achieve hedge accounting treatment are referred to as economic hedges. The changes in fair value of these instruments are recorded in our consolidated statements of operations in the period in which the change occurs. In a fair value hedge, changes in the fair value of the derivative and, to the extent that it is effective, changes in the fair value of the hedged asset or liability attributable to the hedged risk are recorded through current period earnings in the same financial statement category as the hedged item. In a cash flow hedge, the effective portion of the change in the fair value of the hedging derivative is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings during the same period in which the hedged item affects earnings. The ineffective portion is recognized immediately in noninterest income – other. The Company discontinues hedge accounting when (1) it determines that the derivative is no longer expected to be highly effective in offsetting changes in fair value or cash flows of the designated item; (2) the derivative expires or is sold, terminated, or exercised; (3) the derivative is de-designated from the hedge relationship; or (4) it is no longer probable that a hedged forecasted transaction will occur by the end of the originally specified time period. If the Company determines that the derivative no longer qualifies as a fair value or cash flow hedge and therefore hedge accounting is discontinued, the derivative (if retained) will continue to be recorded on the balance sheet at its fair value with changes in fair value included in current earnings. For a discontinued fair value hedge, the previously hedged item is no longer adjusted for changes in fair value. When the Company discontinues hedge accounting because it is not probable that a forecasted transaction will occur, the derivative will continue to be recorded on the balance sheet at its fair value with changes in fair value included in current earnings, and the gains and losses in accumulated other comprehensive income will be recognized immediately in earnings. When the Company discontinues hedge accounting because the hedging instrument is sold, terminated, or de-designated as a hedge, the amount reported in accumulated other comprehensive income through the date of sale, termination, or de-designation will continue to be reported in accumulated other comprehensive income until the forecasted transaction affects earnings. For fair value hedges that are de-designated, the net gain or loss on the underlying transactions being hedged is amortized to other noninterest income over the remaining contractual life of the loans at the time of de-designation. Changes in the fair value of these derivative instruments after de-designation of fair value hedge accounting are recorded in noninterest income in the consolidated statements of operations. As of December 31, 2015 , the Company had no derivatives that were designated as fair value hedges or cash flow hedges. Interest rate lock commitments ("IRLCs") for single family mortgage loans that we intend to sell are considered free-standing derivatives. For determining the fair value measurement of IRLCs we consider several factors including the fair value in the secondary market of the underlying loan resulting from the exercise of the commitment, the expected net future cash flows related to the associated servicing of the loan and the probability that the loan will not fund according to the terms of the commitment (referred to as a fall-out factor). The value of the underlying loan is affected primarily by changes in interest rates. Management uses forward sales commitments to hedge the interest rate exposure from IRLCs. A forward loan sale commitment protects the Company from losses on sales of loans arising from the exercise of the loan commitments by securing the ultimate sales price and delivery date of the loan. The Company takes into account various factors and strategies in determining the portion of the mortgage pipeline it wants to hedge economically. Unrealized and realized gains and losses on derivative contracts utilized for economically hedging the mortgage pipeline are recognized as part of the net gain on mortgage loan origination and sale activities within noninterest income. The Company is exposed to credit risk if derivative counterparties to derivative contracts do not perform as expected. This risk consists primarily of the termination value of agreements where the Company is in a favorable position. The Company minimizes counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, as appropriate.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-Based Employee Compensation The Company has share-based employee compensation plans as more fully discussed in Note 16, Share-Based Compensation Plan s. Under the accounting guidance for stock compensation, compensation expense recognized includes the cost for share-based awards, such as nonqualified stock options and restricted stock grants, which are recognized as compensation expense over the requisite service period (generally the vesting period) on a straight line basis. For stock awards that vest upon the satisfaction of a market condition, the Company estimates the service period over which the award is expected to vest. If all conditions to the vesting of an award are satisfied prior to the end of the estimated vesting period, any unrecognized compensation costs associated with the portion of the award that vested earlier than expected are immediately recognized in earnings.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value Measurement The term "fair value" is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The Company’s approach is to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. The degree of management judgment involved in estimating the fair value of a financial instrument or other asset is dependent upon the availability of quoted market prices or observable market value inputs for internal valuation models, used for estimating fair value. For financial instruments that are actively traded in the marketplace or whose values are based on readily available market data, little judgment is necessary when estimating the instrument’s fair value. When observable market prices and data are not readily available, significant management judgment often is necessary to estimate fair value. In those cases, different assumptions could result in significant changes in valuation. See Note 17, Fair Value Measurement .
Commitments and Contingencies, Policy [Policy Text Block]	Commitments, Guarantees, and Contingencies U.S. GAAP requires that a guarantor recognize, at the inception of a guarantee, a liability in an amount equal to the fair value of the obligation undertaken in issuing the guarantee. A guarantee is a contract that contingently requires the guarantor to pay a guaranteed party based upon: (a) changes in an underlying asset, liability or equity security of the guaranteed party; or (b) a third party’s failure to perform under a specified agreement. The Company initially records guarantees at the inception date fair value of the obligation assumed and records the amount in other liabilities. For indemnifications provided in sales agreements, a portion of the sale proceeds is allocated to the guarantee, which adjusts the gain or loss that would otherwise result from the transaction. For these indemnifications, the initial liability is amortized to income as the Company’s risk is reduced (i.e., over time as the Company's exposure is reduced or when the indemnification expires). Contingent liabilities, including those that exists as a result of a guarantee or indemnification, are recognized when it becomes probable that a loss has been incurred and the amount of the loss is reasonably estimable. The contingent portion of a guarantee is not recognized if the estimated amount of loss is less than the carrying amount of the liability recognized at inception of the guarantee (as adjusted for any amortization). The Company typically sells loans servicing retained in either a pooled loan securitization transaction with a GSE, a whole loan sale to a GSE, or a whole loan sale to market participants such as other financial institutions, who purchase the loans for investment purposes or include them in a private label securitization transaction, or the loans are pooled and sold into a conforming loan securitization with a government-sponsored enterprise (“GSE”), provided loan origination parameters conform to GSE guidelines. Substantially all of the Company’s loan sales are pooled loan securitization transactions with GSEs. These conforming loan securitizations are guaranteed by GSEs, such as Fannie Mae, Ginnie Mae and Freddie Mac. The Company may be required to repurchase mortgage loans or indemnify loan purchasers due to defects in the origination process of the loan, such as documentation errors, underwriting errors and judgments, early payment defaults and fraud. These obligations expose the Company to any credit loss on the repurchased mortgage loans after accounting for any mortgage insurance that it may receive. Generally, the maximum amount of future payments the Company would be required to make for breaches of these representations and warranties would be equal to the unpaid principal balance of such loans that are deemed to have defects that were sold to purchasers plus, in certain circumstances, accrued and unpaid interest on such loans and certain expenses. See Note 13, Commitments, Guarantees, and Contingencies . The Company sells multifamily loans through the Fannie Mae Delegated Underwriting and Servicing Program ("DUS" ® ) (DUS® is a registered trademark of Fannie Mae.) that are subject to a credit loss sharing arrangement. The Company may also from time to time sell loans with recourse. When loans are sold with recourse or subject to a loss sharing arrangement, a liability is recorded based on the estimated fair value of the obligation under the accounting guidance for guarantees. These liabilities are included within other liabilities. See Note 13, Commitments, Guarantees, and Contingencies .
Earnings Per Share, Policy [Policy Text Block]	Earnings per Share Basic earnings per share ("EPS") is computed by dividing net income available to common shareholders by the weighted average common shares outstanding during the period. Diluted EPS is computed by dividing net income available to common shareholders by the weighted average common shares outstanding, plus the effect of common stock equivalents (for example, stock options and unvested restricted stock). Stock options issued under stock-based compensation plans that have an antidilutive effect and shares of restricted stock whose vesting is contingent upon conditions that have not been satisfied at the end of the period are excluded from the computation of diluted EPS. Weighted average common shares outstanding include shares held by the HomeStreet, Inc. 401(k) Savings Plan.
Segment Reporting, Policy [Policy Text Block]	Business Segments The Company's business segments are determined based on the products and services provided, as well as the nature of the related business activities, and they reflect the manner in which financial information is regularly reviewed by the Company's chief operating decision maker for the purpose of allocating resources and evaluating the performance of the Company's businesses. The results for these business segments are based on management’s accounting process, which assigns income statement items and assets to each responsible operating segment. This process is dynamic and is based on management's view of the Company's operations. See Note 19, Business Segments .

The amortization expense for future periods was calculated by applying the same quantitative factors, such as actual MSR prepayment experience and discount rates, which were used to determine amortization expense. These factors are inherently subject to significant fluctuations, primarily due to the effect that changes in interest rates may have on expected loan prepayment experience. Accordingly, any projection of MSR amortization in future periods is limited by the conditions that existed at the time the calculations were performed and may not be indicative of actual amortization expense that will be recorded in future periods.

Fair Value Measurement Methodologies [Table Text Block]	The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions, and classification of the Company’s assets and liabilities. Asset/Liability class Valuation methodology, inputs and assumptions Classification Cash and cash equivalents Carrying value is a reasonable estimate of fair value based on the short-term nature of the instruments. Estimated fair value classified as Level 1. Investment securities Investment securities available for sale Observable market prices of identical or similar securities are used where available. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 2 recurring fair value measurement Investment securities held to maturity Observable market prices of identical or similar securities are used where available. If market prices are not readily available, value is based on discounted cash flows using the following significant inputs: • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Carried at amortized cost. Loans held for sale Single family loans, excluding loans transferred from held for investment Fair value is based on observable market data, including: • Quoted market prices, where available • Dealer quotes for similar loans • Forward sale commitments Level 2 recurring fair value measurement When not derived from observable market inputs, fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Estimated fair value classified as Level 3. Loans originated as held for investment and transferred to held for sale Fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Carried at lower of amortized cost or fair value. Multifamily loans (DUS) The sale price is set at the time the loan commitment is made, and as such subsequent changes in market conditions have a very limited effect, if any, on the value of these loans carried on the consolidated statements of financial condition, which are typically sold within 30 days of origination. Carried at lower of amortized cost or fair value. Estimated fair value classified as Level 2. Asset/Liability class Valuation methodology, inputs and assumptions Classification Loans held for investment Loans held for investment, excluding collateral dependent loans and loans transferred from held for sale Fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments For the carrying value of loans see Note 1–Summary of Significant Accounting Policies. Loans held for investment, collateral dependent Fair value is based on appraised value of collateral, which considers sales comparison and income approach methodologies. Adjustments are made for various factors, which may include: • Adjustments for variations in specific property qualities such as location, physical dissimilarities, market conditions at the time of sale, income producing characteristics and other factors Carried at lower of amortized cost or fair value of collateral, less the estimated cost to sell. Loans held for investment transferred from loans held for sale Fair value is based on discounted cash flows, which considers the following inputs: • Current lending rates for new loans • Expected prepayment speeds • Estimated credit losses • Market liquidity adjustments Level 3 recurring fair value measurement Mortgage servicing rights Single family MSRs For information on how the Company measures the fair value of its single family MSRs, including key economic assumptions and the sensitivity of fair value to changes in those assumptions, see Note 12 , Mortgage Banking Operations . Level 3 recurring fair value measurement Multifamily MSRs Fair value is based on discounted estimated future servicing fees and other revenue, less estimated costs to service the loans. Carried at lower of amortized cost or fair value Estimated fair value classified as Level 3. Derivatives Interest rate swaps Interest rate swaptions Forward sale commitments Fair value is based on quoted prices for identical or similar instruments, when available. Level 2 recurring fair value measurement Interest rate lock commitments The fair value considers several factors including: • Fair value of the underlying loan based on quoted prices in the secondary market, when available. • Value of servicing • Fall-out factor Level 3 recurring fair value measurement Asset/Liability class Valuation methodology, inputs and assumptions Classification Other real estate owned (“OREO”) Fair value is based on appraised value of collateral, less the estimated cost to sell. See discussion of "loans held for investment, collateral dependent" above for further information on appraisals. Carried at lower of amortized cost or fair value of collateral (Level 3), less the estimated cost to sell. Federal Home Loan Bank stock Carrying value approximates fair value as FHLB stock can only be purchased or redeemed at par value. Carried at par value. Estimated fair value classified as Level 2. Deposits Demand deposits Fair value is estimated as the amount payable on demand at the reporting date. Carried at historical cost. Estimated fair value classified as Level 2. Fixed-maturity certificates of deposit Fair value is estimated using discounted cash flows based on market rates currently offered for deposits of similar remaining time to maturity. Carried at historical cost. Estimated fair value classified as Level 2. Federal Home Loan Bank advances Fair value is estimated using discounted cash flows based on rates currently available for advances with similar terms and remaining time to maturity. Carried at historical cost. Estimated fair value classified as Level 2. Long-term debt Fair value is estimated using discounted cash flows based on current lending rates for similar long-term debt instruments with similar terms and remaining time to maturity. Carried at historical cost. Estimated fair value classified as Level 2.
