Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: HomeStreet, Inc., a State of Washington corporation organized in 1921 (the "Corporation"), is a Washington-based diversified financial services holding company whose operations are primarily conducted through its wholly owned subsidiaries (collectively the "Company") HomeStreet Capital Corporation, HomeStreet Statutory Trusts and HomeStreet Bank (the "Bank"), and the Bank's subsidiaries, Continental Escrow Company, HomeStreet Foundation, HS Properties, Inc., HS Evergreen Corporate Center LLC, and Union Street Holdings LLC. The Company is principally engaged in commercial banking, mortgage banking and consumer/retail banking activities serving customers primarily in the Western United States. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Actual results could differ significantly from those estimates. Certain amounts in the financial statements from prior periods have been reclassified to conform to the current financial statement presentation. These unaudited interim financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the periods presented. These adjustments are of a normal recurring nature, unless otherwise disclosed in this Quarterly Report on Form 10-Q. The results of operations in the interim financial statements do not necessarily indicate the results that may be expected for the full year. The interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission ("2020 Annual Report on Form 10-K"). Recent Accounting Developments In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles in Topic 740 in GAAP. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted this ASU on January 1, 2021 and it did not have a material effect on the Company’s financial position, results of operations or financial statement disclosures. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848). This ASU provides optional expedients and exceptions for contracts, hedging relationships, and other transactions that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)," which clarifies certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting applied to derivatives that are affected by the transition to alternative rates. The ASUs are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is in the process of evaluating the provisions of these ASUs, but does not expect them to have a material impact on the Company’s financial position, results of operations or financial statement disclosures.

The Company has evaluated AFS securities that are in an unrealized loss position and has determined that the decline in value is temporary and is related to the change in market interest rates since purchase. 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 September 30, 2021 or December 31, 2020. In addition, as of September 30, 2021 and December 31, 2020, 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.

Receivables [Abstract]
LOANS AND CREDIT QUALITY	LOANS AND CREDIT QUALITY: The Company's LHFI is divided into two portfolio segments, commercial loans and consumer loans. 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 non-owner occupied commercial real estate, multifamily, construction and land development, owner occupied commercial real estate and commercial business loans within the commercial loan portfolio segment. LHFI consists of the following: (in thousands) At September 30, 2021 At December 31, 2020 Commercial real estate loans Non-owner occupied commercial real estate $ 754,031 $ 829,538 Multifamily 2,090,156 1,428,092 Construction/land development 514,322 553,695 Total 3,358,509 2,811,325 Commercial and industrial loans Owner occupied commercial real estate 450,350 467,256 Commercial business 435,756 645,723 Total 886,106 1,112,979 Consumer loans Single family (1) 793,927 915,123 Home equity and other 315,715 404,753 Total 1,109,642 1,319,876 Total LHFI 5,354,257 5,244,180 Allowance for credit losses ("ACL") (54,516) (64,294) Total LHFI less ACL $ 5,299,741 $ 5,179,886 (1) Includes $4.5 million and $7.1 million at September 30, 2021 and December 31, 2020, respectively, of loans where a fair value option election was made at the time of origination and, therefore, are carried at fair value with changes in fair value recognized in the consolidated income statements. Loans totaling $1.7 billion and $1.4 billion at September 30, 2021 and December 31, 2020, respectively, were pledged to secure borrowings from the Federal Home Loan Bank ("FHLB") and loans totaling $430 million and $569 million at September 30, 2021 and December 31, 2020, respectively, were pledged to secure borrowings from the Federal Reserve Bank. Credit Risk Concentrations LHFI are primarily secured by real estate located in the Pacific Northwest, California and Hawaii. At September 30, 2021 and December 31, 2020, multifamily loans in the state of California represented 29% and 19% of the total LHFI portfolio, respectively. Credit Quality Management considers the level of ACL to be appropriate to cover credit losses expected over the life of the loans for the LHFI portfolio. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of the Bank’s historical loss experience and eight qualitative factors for current and forecasted periods. During the quarter ended March 31, 2020, the qualitative factors increased significantly due to the forecasted impacts of the COVID-19 pandemic. The qualitative factors have remained at a high level due to the continued uncertainty regarding the impact of the COVID-19 pandemic. Included in the qualitative factors are estimates of potential loss exposure which are based on forbearance activities relating to the COVID-19 pandemic in the Bank’s loan portfolio. Due to improvements in economic conditions, the Company recorded a $5 million and $9 million recovery of the allowance for credit losses in the third quarter of 2021 and nine months ended September 30, 2021, respectively. As of September 30, 2021, the Bank expects that over the two-year forecast period, the markets in which it operates will have a modest improvement in single family and multifamily collateral values, but deterioration in commercial real estate collateral values with negative risk factors peaking in the first year. The Bank also expects that over the two-year forecast period, the markets in which it operates will have a modest deterioration in the economic outlook, with negative risk factors peaking in the first year. In addition to the ACL for LHFI, the Company maintains a separate allowance for unfunded loan commitments which is included in accounts payable and other liabilities on our consolidated balance sheets. The allowance for unfunded commitments was $2.5 million and $1.6 million at September 30, 2021 and December 31, 2020, respectively. The Bank has elected to exclude accrued interest receivable from the evaluation of the ACL. Accrued interest on LHFI was $18.1 million and $21.2 million at September 30, 2021 and December 31, 2020, respectively, and was reported in other assets in the consolidated balance sheets.

In addition, interagency guidance issued by federal banking regulators and endorsed by the FASB staff has indicated that borrowers who receive relief are not experiencing financial difficulty if they meet the following qualifying criteria: • The modification is in response to the National Emergency related to the COVID-19 pandemic; • The borrower was current at the time the modification program was implemented; and • The modification is short-term We have elected to apply temporary relief under Section 4013 of the CARES Act to certain eligible modifications and will not treat qualifying loan modifications as TDRs for accounting or disclosure purposes. Additionally, eligible short-term loan modifications subject to the practical expedient in the interagency guidance will not be treated as TDRs for accounting or disclosure purposes if they qualify.

GUARANTEES AND MORTGAGE REPURCHASE LIABILITY	GUARANTEES AND MORTGAGE REPURCHASE LIABILITY: 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 DUS program, the Company and Fannie Mae share losses on a pro rata basis, where the Company is responsible for losses incurred up to one-third of principal balance on each loan with two-thirds of the loss covered by Fannie Mae. 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 September 30, 2021 and December 31, 2020, the total unpaid principal balance of loans sold under this program was $1.9 billion and $1.8 billion, respectively. The Company's reserve liability related to this arrangement totaled $0.7 million and $2.1 million at September 30, 2021 and December 31, 2020, respectively. There were no actual losses incurred under this arrangement during the quarters and nine months ended September 30, 2021 and 2020.In the ordinary course of business, the Company sells residential mortgage loans to GSEs and other entities. Under the terms of these sales agreements, 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. 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 $5.6 billion and $6.0 billion as of September 30, 2021 and December 31, 2020, respectively. At September 30, 2021 and December 31, 2020, 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 balance sheets, of $1.4 million and $2.1 million, respectively.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	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. 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 valued at fair value on a recurring basis. Asset/Liability class Valuation methodology, inputs and assumptions Classification Investment securities Investment securities AFS Observable market prices of identical or similar securities are used where available. Level 2 recurring fair value measurement. 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 3 recurring fair value measurement. LHFS 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: • Benchmark yield curve • Estimated discount spread to the benchmark yield curve • Expected prepayment speeds Estimated fair value classified as Level 3. 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 6 , Mortgage Banking Operations . Level 3 recurring fair value measurement. Derivatives Eurodollar futures Fair value is based on closing exchange prices. Level 1 recurring fair value measurement. Interest rate swaps Fair value is based on quoted prices for identical or similar instruments, when available. When quoted prices are not available, fair value is based on internally developed modeling techniques, which require the use of multiple observable market inputs including: 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.

Level 3 Recurring Fair Value Measurements The Company's level 3 recurring fair value measurements consist of investment securities AFS, single family MSRs, single family LHFI where fair value option was elected, certain single family LHFS 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 quarters and nine months ended September 30, 2021 and 2020, see Note 6, Mortgage Banking Operations of this Quarterly Report on Form 10-Q. 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 LHFS, 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 LHFS 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 single family loans that have been transferred from held for sale to held for investment are sensitive to changes in the benchmark interest rate which might result in a significantly higher or lower fair value measurement. 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 had 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 $4.5 million and $7.1 million at September 30, 2021 and December 31, 2020, respectively. The following information presents significant Level 3 unobservable inputs used to measure fair value of certain assets: (dollars in thousands) Fair Value Valuation Significant Unobservable Low High Weighted Average September 30, 2021 Investment securities AFS $ 2,514 Income approach Implied spread to benchmark interest rate curve 2.00% 2.00% 2.00% Single family LHFI 4,507 Income approach Implied spread to benchmark interest rate curve 3.14% 8.59% 4.73% Interest rate lock commitments, net 4,609 Income approach Fall-out factor 0.87% 24.05% 12.18% Value of servicing 0.39% 1.52% 1.19% December 31, 2020 Investment securities AFS $ 2,710 Income approach Implied spread to benchmark interest rate curve 2.00% 2.00% 2.00% Single family LHFI 7,108 Income approach Implied spread to benchmark interest rate curve 3.96% 10.64% 6.23% Interest rate lock commitments, net 17,392 Income approach Fall-out factor 1.97% 38.38% 15.53% Value of servicing 0.41% 1.44% 0.97% We had no LHFS where the fair value was not derived with significant observable inputs at September 30, 2021 and December 31, 2020.

These assets include certain LHFI and OREO that are carried at the lower of cost or fair value of the underlying collateral, less the estimated costs 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. We have omitted disclosure related to quantitative inputs given the insignificance of assets measured on a nonrecurring basis. 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 LHFI 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 LHFI that are not collateralized by real estate and 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 table present assets classified as Level 3 assets that had changes in their recorded fair value for the periods indicated and what we still held at the end of the respective reporting period: (in thousands) Fair Value Level 1 Level 2 Level 3 Total Gains (Losses) At or for the Quarter Ended September 30, 2021 LHFI (1) $ 1,121 $ — $ — $ 1,121 $ (8) At or for the Quarter Ended September 30, 2020 LHFI (1) $ 3,302 $ — $ — $ 3,302 $ (2,054) At or for the Nine Months Ended September 30, 2021 LHFI (1) $ 1,121 $ — $ — $ 1,121 $ (70) At or for the Nine Months Ended September 30, 2020 LHFI (1) $ 3,302 $ — $ — $ 3,302 $ (2,184) (1) Represents the carrying value of loans for which adjustments are based on the fair value of the collateral.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (Policies)	9 Months Ended
	Sep. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Actual results could differ significantly from those estimates.
Reclassifications	Certain amounts in the financial statements from prior periods have been reclassified to conform to the current financial statement presentation.
Recent Accounting Developments	Recent Accounting Developments In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles in Topic 740 in GAAP. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted this ASU on January 1, 2021 and it did not have a material effect on the Company’s financial position, results of operations or financial statement disclosures. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848). This ASU provides optional expedients and exceptions for contracts, hedging relationships, and other transactions that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)," which clarifies certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting applied to derivatives that are affected by the transition to alternative rates. The ASUs are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is in the process of evaluating the provisions of these ASUs, but does not expect them to have a material impact on the Company’s financial position, results of operations or financial statement disclosures.
Derivatives and Hedging Activities	To reduce the risk of significant interest rate fluctuations on the value of certain assets and liabilities, such as single family mortgage LHFS and MSRs, the Company utilizes derivatives as economic hedges
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. 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 valued at fair value on a recurring basis. Asset/Liability class Valuation methodology, inputs and assumptions Classification Investment securities Investment securities AFS Observable market prices of identical or similar securities are used where available. Level 2 recurring fair value measurement. 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 3 recurring fair value measurement. LHFS 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: • Benchmark yield curve • Estimated discount spread to the benchmark yield curve • Expected prepayment speeds Estimated fair value classified as Level 3. 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 6 , Mortgage Banking Operations . Level 3 recurring fair value measurement. Derivatives Eurodollar futures Fair value is based on closing exchange prices. Level 1 recurring fair value measurement. Interest rate swaps Fair value is based on quoted prices for identical or similar instruments, when available. When quoted prices are not available, fair value is based on internally developed modeling techniques, which require the use of multiple observable market inputs including: 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.

Fair Value Disclosures [Abstract]
Fair Value Measurement Methodologies	The following table summarizes the fair value measurement methodologies, including significant inputs and assumptions and classification of the Company's assets and liabilities valued at fair value on a recurring basis. Asset/Liability class Valuation methodology, inputs and assumptions Classification Investment securities Investment securities AFS Observable market prices of identical or similar securities are used where available. Level 2 recurring fair value measurement. 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 3 recurring fair value measurement. LHFS 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: • Benchmark yield curve • Estimated discount spread to the benchmark yield curve • Expected prepayment speeds Estimated fair value classified as Level 3. 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 6 , Mortgage Banking Operations . Level 3 recurring fair value measurement. Derivatives Eurodollar futures Fair value is based on closing exchange prices. Level 1 recurring fair value measurement. Interest rate swaps Fair value is based on quoted prices for identical or similar instruments, when available. When quoted prices are not available, fair value is based on internally developed modeling techniques, which require the use of multiple observable market inputs including: Level 2 recurring fair value measurement.
