ORGANIZATION	'
	NOTE 1 – ORGANIZATION
	INREIT Real Estate Investment Trust (“INREIT”) is a registered, but unincorporated business trust organized in North Dakota in November 2002. INREIT has elected to be taxed as a Real Estate Investment Trust (“REIT”) under Sections 856-860 of the Internal Revenue Code, which requires that 75% of the assets of a REIT must consist of real estate assets and that 75% of its gross income must be derived from real estate. The net income of the REIT is allocated in accordance with the stock ownership in the same fashion as a regular corporation.
	INREIT previously established an operating partnership (INREIT Properties, LLLP) and transferred all of its assets and liabilities to the operating partnership in exchange for general partnership units. As the general partner, INREIT has management responsibility for all activities of the operating partnership. As of September 30, 2013 and December 31, 2012, INREIT owned approximately 29.7% and 32.3%, respectively, of the operating partnership. The operating partnership is the 100% owner of 36 single asset limited liability companies and the 81.25% owner, and the 40.26% owner in 2 additional single asset entities, an LLP and LLC, respectively.

PRINCIPAL ACTIVITY AND SIGNIFICANT ACCOUNTING POLICIES	'
	NOTE 2 – PRINCIPAL ACTIVITY AND SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2012, which have previously been filed with the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted from this report on Form 10-Q pursuant to the rules and regulations of the SEC.
	The results for the interim periods shown in this report are not necessarily indicative of future financial results. The accompanying consolidated balance sheet as of September 30, 2013 and consolidated statements of operations and other comprehensive income, consolidated statements of shareholders’ equity, and consolidated statements of cash flows for the three and nine month periods ended September 30, 2013 and 2012, as applicable, have not been audited by our independent registered public accounting firm. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary to present fairly our unaudited consolidated financial position as of September 30, 2013 and our unaudited consolidated statements of operations and other comprehensive income, unaudited consolidated statements of shareholders’ equity and our unaudited consolidated statements of cash flows for the three and nine month periods ended September 30, 2013 and 2012, as applicable. These adjustments are of a normal recurring nature.
	Principles of Consolidation
	The consolidated financial statements include the accounts of INREIT, INREIT Properties, LLLP, 36 single asset limited liability companies and a single asset LLC that the operating partnership is the 81.25% owner. All significant intercompany transactions and balances have been eliminated in consolidation.
	Additionally, we evaluate the need to consolidate affiliates based on standards set forth in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”). In determining whether we have a requirement to consolidate the accounts of an entity, management considers factors such as our ownership interest, our authority to make decisions and contractual and substantive participating rights of the limited partners and shareholders, as well as whether the entity is a variable interest entity (VIE) for which we have both a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and b) the obligation to absorb losses or the right to receive benefits from the VIE that could be potentially significant to the VIE.

	Principal Business Activity
	INREIT currently owns directly and indirectly 116 properties.

The consolidated financial statements include 100% of each subsidiary’s assets, liabilities, operations and cash flows, with the interests not owned by the operating partnership reflected as “noncontrolling interests in operating partnership”. All significant intercompany accounts have been eliminated in consolidation.
Investment in Unconsolidated Affiliates
We account for unconsolidated affiliates using the equity method of accounting per guidance established under ASC 323, Investments – Equity Method and Joint Ventures (“ASC 323”). The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the affiliates’ earnings and distributions. We evaluate the carrying amount of the investments for impairment in accordance with ASC 323. Unconsolidated affiliates are reviewed for potential impairment if the carrying amount of the investment exceeds its fair value. An impairment charge is recorded when an impairment is deemed to be other-than-temporary. To determine whether impairment is other-than-temporary, we consider the financial condition of the investment. The evaluation of an investment in an affiliate for potential impairment can require our management to exercise significant judgments. No impairment losses were recorded related to the unconsolidated affiliates for the three and nine months ended September 30, 2013 and 2012.
Investment in unconsolidated affiliates as of September 30, 2013 consists of the operating partnership’s 40.26% interest in a single asset limited liability company which owns a 144 unit residential, multi-tenant apartment complex in Bismarck, North Dakota; the operating partnership’s 100.00% interest in a single asset limited liability company which holds a 50.00% interest in a 183,000 square feet of commercial space in Grand Forks, North Dakota; and the operating partnership’s 66.67% interest as tenant in common in an office building with approximately 75,000 square feet of commercial space in Fargo, North Dakota. These investments are not consolidated as the entities do not qualify as variable interest entities and do not meet the control requirements for consolidation, as defined in ASC 810. The operating partnership and the respective affiliate partners must approve significant decisions about the applicable entities activities. As of September 30, 2013, the unconsolidated affiliates held total assets of $28.4 million and mortgage notes payable of $21.3 million.
Concentration of Credit Risk
Our cash balances are maintained in various bank deposit accounts. The bank deposit amounts in these accounts may exceed federally insured limits at various times throughout the year.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Real Estate Investments
We account for our property acquisitions by allocating the purchase price of a property to the property’s assets based on management’s estimates of fair value. Techniques used to estimate fair value include appraisals of the properties by a certified independent appraiser at the time of acquisition.
Furniture and fixtures are stated at cost less accumulated depreciation. All costs associated with the development and construction of real estate investments, including acquisition fees and interest, are capitalized as a cost of the property. Expenditures for renewals and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Expenditures for routine maintenance and repairs, which do not add to the value or extend useful lives, are charged to expense as incurred.
Depreciation is provided for over the estimated useful lives of the individual assets using the straight-line method over the following estimated useful lives:
Buildings and improvements			40 years
Furniture and fixtures			9 years
Depreciation expense for the three months ended September 30, 2013 and 2012 totaled $2.7 million and $2.4 million, respectively. Depreciation expense for the nine months ended September 30, 2013 and 2012 totaled $8.0 million and $7.2 million, respectively.
The Company’s investment properties are reviewed for potential impairment at the end of each reporting period or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. At the end of each reporting period, the Company separately determines whether impairment indicators exist for each property.
Examples of situations considered to be impairment indicators include, but are not limited to:
	•		A substantial decline or continued low occupancy rate;
	•		Continued difficulty in leasing space;
	•		Significant financial troubled tenants;
	•		a change in plan to sell a property prior to the end of its useful life or holding period;
	•		a significant decrease in market price not in line with general market trends; and
	•		any other quantitative or qualitative events or factors deemed significant by the Company’s management or board of trustees.
If the presence of one or more impairment indicators as described above is identified at the end of the reporting period or throughout the year with respect to a property, the asset is tested for recoverability by comparing its carrying value to the estimated future undiscounted cash flows. An investment property is considered to be impaired when the estimated future undiscounted cash flows are less than its current carrying value. When performing a test for recoverability or estimating the fair value of an impaired investment property, the Company makes complex or subjective assumptions which include, but are not limited to:
	•		projected operating cash flows considering factors such as vacancy rates, rental rates, lease terms, tenant financial strength, demographics, holding period and property location;
	•		projected capital expenditures and lease origination costs;
	•		projected cash flows from the eventual disposition of an operating property using a property specific capitalization rate;
	•		comparable selling prices; and
	•		property specific discount rates for fair value estimates as necessary.
To the extent impairment has occurred, the Company will record an impairment charge calculated as the excess of the carrying value of the asset over its fair value for impairment of investment properties. Based on evaluation, management recorded loss on impairment of property of $226,000 for the nine month period ending September 30, 2013. There have been no impairment losses during the nine month period ended September 30, 2012.

We account for our properties held for sale in accordance with ASC 360, Property, Plant and Equipment (“ASC 360”), which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and requires that, in a period in which a component of an entity either has been disposed of or is classified as held for sale, the statements of operations for current and prior periods shall report the results of operations of the component as discontinued operations.
In accordance with ASC 360, at such time as a property is held for sale, such property is carried at the lower of (1) its carrying amount or (2) fair value less costs to sell. In addition, a property being held for sale ceases to be depreciated. We classify operating properties as properties held for sale in the period in which all of the following criteria are met:
	•		management, having the authority to approve the action, commits to a plan to sell the asset;
	•		the asset is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets;
	•		an active program to locate a buyer and other actions required to complete the plan to sell the asset has been initiated;
	•		the sale of the asset is probable and the transfer of the asset is expected to qualify for recognition as a completed sale within one year;
	•		the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and
	•		given the actions required to complete the plan to sell the asset, it is unlikely that significant changes to the plan would be made or that the plan would be withdrawn.
There was one property classified as held for sale at September 30, 2013, and no properties classified as held for sale at December 31, 2012. See Note 20.
Cash and Cash Equivalents
We classify highly liquid investments with a maturity of three months or less when purchased as cash equivalents.
Receivables
Receivables consist primarily of amounts due for rent and real estate taxes. The receivables are non-interest bearing. The carrying amount of receivables is reduced by an amount that reflects management’s best estimates of the amounts that will not be collected. As of September 30, 2013 and December 31, 2012, management determined that no allowance was necessary for uncollectible receivables.
Rental Incentives
Rental incentives consist of up-front cash payments to lessees to sign the lease. Rental incentives are amortized against rental income over the term of the lease.
Intangible Assets
Lease intangibles are a purchase price allocation recorded on property acquisition. The lease intangibles represent the estimated value of in-place leases at above or below market lease terms. Lease intangibles are amortized over the term of the related lease.
The carrying amount of intangible assets is regularly reviewed for indicators of impairments in value. Impairment is recognized only if the carrying amount of the intangible asset is considered to be unrecoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and the estimated fair value of the asset. Based on the review, management determined that no impairment charges were necessary at September 30, 2013 or December 31, 2012.
Financing Costs
Financing costs incurred in connection with financing have been capitalized and are being amortized over the life of the financing using the effective interest method.
Noncontrolling Interest
Interests in the operating partnership held by limited partners are represented by limited partnership units. The operating partnership’s income is allocated to holders of units based upon the ratio of their holdings to the total units outstanding during the period. Capital contributions, distributions, syndication costs, and profits and losses are allocated to noncontrolling interests in accordance with the terms of the operating partnership agreement.
Syndication Costs
Syndication costs consist of costs paid to attorneys, accountants, and selling agents, related to the raising of capital. Syndication costs are recorded as a reduction to beneficial and noncontrolling interest.
Federal Income Taxes
We have elected to be taxed as a REIT under the Internal Revenue Code, as amended. A REIT calculates taxable income similar to other domestic corporations, with the major difference being that a REIT is entitled to a deduction for dividends paid. A REIT is generally required to distribute each year at least 90% of its taxable income. If it chooses to retain the remaining 10% of taxable income, it may do so, but it will be subject to a corporate tax on such income. REIT shareholders are taxed on REIT distributions of ordinary income in the same manner as they are taxed on other corporate distributions.
We intend to continue to qualify as a REIT and, as such, will not be taxed on the portion of the income that is distributed to the shareholders. In addition, we intend to distribute all of our taxable income; therefore, no provisions or liabilities for income taxes have been recorded in the financial statements.
INREIT conducts its business activity as an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) through its Operating Partnership. The Operating Partnership is organized as a limited liability limited partnership. Income or loss is allocated to the partners in accordance with the provisions of the Internal Revenue Code 704(b) and 704(c). UPREIT status allows non-recognition of gain by an owner of appreciated real estate if that owner contributes the real estate to a partnership in exchange for partnership interest. The conversion of partnership interest to shares of beneficial interest in the REIT will be a taxable event to the limited partner.
We follow ASC Topic 740, Income Taxes, to recognize, measure, present and disclose in our consolidated financial statements uncertain tax positions that we have taken or except to take on a tax return. As of September 30, 2013 and December 31, 2012 we did not have any liabilities for uncertain tax positions that we believe should be recognized in our consolidated financial statements. We are no longer subject to Federal and State tax examinations by tax authorities for years before 2010.
The operating partnership has elected to record related interest and penalties, if any, as income tax expense on the consolidated statements of operations and other comprehensive income.
Recent Accounting Pronouncements
As of September 30, 2013, the impact of recent accounting pronouncements is not considered to be material.
Revenue Recognition
We recognize revenue in accordance with ASC Topic 605, Revenue Recognition, or ASC Topic 605. ASC Topic 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed and determinable; and (4) collectability is reasonably assured.
We derive over 95% of our revenues from tenant rents and other tenant-related activities. We lease multifamily residential apartments under operating leases and substantially all of our apartment leases are for a term of one year or less. Rental income and other property revenues are recorded when due from tenants and is recognized monthly as it is earned pursuant to the terms of the underlying leases. Other property revenues consist primarily of laundry, application and other fees charged to tenants.
We lease commercial space primarily under long-term lease agreements. Commercial tenant rents include base rents, expense reimbursements (such as common area maintenance, real estate taxes and utilities), and straight-line rents. We record base rents on a straight-line basis. The monthly base rent income according to the terms of our leases is adjusted so that an average monthly rent is recorded for each tenant over the term of its lease. The straight-line rent adjustment increased revenue by $79,000 and $70,000 for the three months ended September 30, 2013 and 2012, respectively. The straight-line rent adjustment increased revenue by $304,000 and $202,000 for the nine months ended September 30, 2013 and 2012, respectively. The straight-line receivable balance included in receivables on the consolidated balance sheets as of September 30, 2013 and December 31, 2012 was $2.2 million and $1.9 million, respectively. We receive payments for expense reimbursements from substantially all our multi-tenant commercial tenants throughout the year based on estimates. Differences between estimated recoveries and the final billed amounts, which generally are immaterial, are recognized in the subsequent year.
Earnings per Common Share
Basic earnings per common share is computed by dividing net income available to common shareholders (the “numerator”) by the weighted average number of common shares outstanding (the “denominator”) during the period. INREIT had no dilutive potential common shares as of September 30, 2013 or 2012, and therefore, basic earnings per common share was equal to diluted earnings per common share for both periods.
For the three months ended September 30, 2013 and 2012, INREIT’s denominators for the basic and diluted earnings per common share were approximately 5.4 million and 5.0 million, respectively. For the nine months ended September 30, 2013 and 2012, INREIT’s denominators for the basic and diluted earnings per common share were approximately 5.4 million and 4.5 million, respectively.
Reclassifications
Certain amounts previously reported in our quarterly report ended September 30, 2012 have been reclassified to conform to held for sale and discontinued operations presentations in 2013.

Segment Reporting [Abstract]	'
SEGMENT REPORTING	'
	NOTE 3 – SEGMENT REPORTING
	We report our results in two reportable segments: residential and commercial properties. Our residential properties include multi-family and assisted senior living properties. Our commercial properties include retail, office, restaurant and medical properties. We assess and measure operating results based on net operating income (“NOI”), which we define as total real estate segment revenues less real estate expenses (which consist of real estate taxes, property management fees, utilities, repairs and maintenance, insurance and direct administrative costs). We believe NOI is an important measure of operating performance even though it should not be considered an alternative to net income or cash flow from operating activities. NOI is unaffected by financing, depreciation, amortization, legal and professional fees and other general and administrative expenses. The accounting policies of each segment are consistent with those described in Note 2 of this report.
	Segment Revenues and Net Operating Income
	The revenues and net operating income for these reportable segments are summarized as follows for the three and nine month periods ended September 30, 2013 and 2012, along with reconciliations to the consolidated financial statements. Segment assets are also reconciled to total assets as reported in the consolidated financial statements.

HEDGING ACTIVITIES	'
	NOTE 5 – HEDGING ACTIVITIES
	As part of our interest rate risk management strategy, we use derivative instruments to minimize significant unanticipated earnings fluctuations that may arise from rising variable interest rate costs associated with existing borrowings. To meet these objectives, we have entered into interest rate swaps for the notional amount of $1.3 million and $2.4 million to provide a fixed rate of 7.25% and 2.57%, respectively. The swaps mature in April 2020 and December 2017, respectively. The swaps were issued at approximate market terms and thus no fair value adjustment was recorded at inception.
	The carrying amount of the swaps have been adjusted to their fair values at the end of the quarter, which because of changes in forecasted levels of LIBOR resulted in reporting a liability for the fair value of the future net payments forecasted under the swaps. The interest rate swaps are accounted for as effective hedges in accordance with ASC 815-20 whereby they are recorded at fair value and changes in fair value are recorded to comprehensive income. As of September 30, 2013 and December 31, 2012, we have recorded a liability and other comprehensive loss of $347,000 and $492,000, respectively.

	We have an $15.0 million variable rate (1-month LIBOR plus 2.35%) line of credit agreement with Wells Fargo Bank, which expires in July 2015; a $1.0 million variable rate (prime rate) unsecured line of credit agreement and a $3.0 million variable rate (prime rate less 0.5%) line of credit agreement with Bremer Bank, which expire in November 2013 and 2014, respectively; and a $2.0 million variable rate (prime rate) line of credit agreement with Bell State Bank & Trust, which expires in June 2014. The lines of credit are secured by properties in Duluth, Minnesota; St. Cloud, Minnesota; Minneapolis/St. Paul, Minnesota, Moorhead, Minnesota and Fargo, North Dakota, respectively. At September 30, 2013, there was no balance outstanding on the lines of credit, leaving $21.0 million unused under the agreements. At December 31, 2012, there was no balance outstanding on the lines of credit, leaving $17.0 million unused under the agreements. The line of credit agreements include covenants that, in part, impose maintenance of certain debt service coverage and debt to net worth ratios. As of September 30, 2013 and December 31, 2012, we were in compliance with all covenants.
	Subsequent to September 30, 2013 the unsecured line of credit with Bremer Bank was renewed and the maturity extended to October 2014. The interest rate will equal the greater of the prime rate or 3.25%.

FAIR VALUE MEASUREMENT	'
	NOTE 9 – FAIR VALUE MEASUREMENT
	The following table presents the carrying value and estimated fair value of the Company’s financial instruments:
			September 30, 2013				December 31, 2012
			Carrying				Carrying
			Value		Fair Value		Value		Fair Value
			(in thousands)
	Financial liabilities:
	Mortgage notes payable		$	213,323	$	233,926	$	208,961	$	221,570
	Fair value of interest rate swaps		$	347	$	347	$	492	$	492
	The carrying values shown in the table are included in the consolidated balance sheets under the indicated captions.
	ASC 820-10 established a three-level valuation hierarchy for fair value measurement. Management uses these valuation techniques to establish the fair value of the assets at the measurement date. These valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s assumptions. These two types of inputs create the following fair value hierarchy:
		•		Level 1 – Quoted prices for identical instruments in active markets;
		•		Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose significant inputs are observable;
		•		Level 3 – Instruments whose significant inputs are unobservable.
	The guidance requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.
	Recurring Fair Value Measurements
	The following table presents the Company’s financial instruments, which are measured at fair value on a recurring basis, by the level in the fair value hierarchy within which those measurements fall. Methods and assumptions used to estimate the fair value of these instruments are described after the table.
			Level 1		Level 2		Level 3		Total

	December 31, 2012
	Fair value of interest rate swap		$	—	$	492	$	—	$	492
	Fair value of interest rate swap: The fair value of the interest rate swap is determined using a discounted cash flow analysis on the expected future cash flows of the derivative. This analysis utilizes observable market data including forward yield curves and implied volatilities to determine the market’s expectation of the future cash flows of the variable component. The fixed and variable components of the derivative are then discounted using calculated discount factors developed based on the LIBOR swap rate and are aggregated to arrive at a single valuation for the period. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of September 30, 2013 and December 31, 2012, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation. As a result, the Company has determined that its derivative valuations in their entirety are classified within Level 2 of the fair value hierarchy. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered any applicable credit enhancements. The Company’s derivative instruments are further described in Note 5.
	Nonrecurring Fair Value Measurements
	As discussed in Note 4, the Company recorded an impairment charge to write the carrying value down to estimated fair value for a certain investment properties after determining that its carrying value exceeded the projected undiscounted cash flows based upon the estimated holding period for such assets. Estimated fair value is determined by the Company utilizing discounted cash flow models, third-party broker valuation estimates, appraisals, bona fide purchase offers or the expected sales price from an executed sales agreement. Capitalization and discount rates utilized within discounted cash flows models are based upon observable rates that the Company believes to be within a reasonable range of current market rates for the property.
	Investment properties measured at fair value on a nonrecurring basis at September 30, 2013 and December 31, 2012, respectively, aggregated by the level within the fair value hierarchy in which those measurements fall are as follows:
			Level 1		Level 2		Level 3		Total		Provision for

	Fair Value Disclosures
	The following table presents the Company’s financial assets and liabilities, which are disclosed at fair value, by the level in the fair value hierarchy within which they fall. Methods and assumptions used to estimate the fair value of these instruments are described after the table.

	December 31, 2012
	Mortgage notes payable		$	—	$	221,570	$	—	$	221,570
	Mortgage notes payable: The Company estimates the fair value of its mortgage notes payable by discounting the future cash flows of each instrument at rates currently offered to the Company for similar debt instruments of comparable maturities by the Company’s lenders. Judgment is used in determining the appropriate rate for each of the Company’s individual mortgages and notes payable based upon the specific terms of the agreement, including the term to maturity, the quality and nature of the underlying property and its leverage ratio. The rates used range from 4.39% to 4.50% and from 4.01% to 4.18% at September 30, 2013 and December 31, 2012, respectively. The fair value of the Company’s matured mortgage payable was determined to be equal to the carrying value of the property because there is no market for a similar debt instrument and the property’s carrying value was determined to be the best estimate of fair value as of September 30, 2013. The Company’s mortgage notes payable are further described in Note 8.

	As of September 30, 2013 and December 31, 2012, outstanding limited partnership units totaled 12.8 million and 11.1 million, respectively. As of September 30, 2013 and 2012, the operating partnership declared distributions of $2.7 million and $2.3 million, respectively, to limited partners to be paid in October 2013 and 2012. Distributions per unit were $0.6300 and $0.6195 during the first nine months of 2013 and 2012, respectively.
	During the first nine months of 2013 there were 4,937 limited partnership units exchanged for 4,937 INREIT common shares valued at $69,000. During the first nine months of 2012, limited partners exchanged 36,000 limited partnership units for 36,000 INREIT common shares valued at $503,000, pursuant to exchange requests.
	Limited partners in the operating partnership have the right to require the operating partnership to redeem their limited partnership units for cash. Upon such a redemption request, INREIT has the right to purchase the limited partnership units in lieu of the operating partnership either with cash or INREIT common shares, in its discretion, on the basis of one limited partnership unit for one INREIT common share. However, payment will be in cash if the issuance of INREIT common shares will cause the shareholder to exceed the ownership limitations, among other reasons. No limited partner will be permitted more than two redemptions during any calendar year, and no redemptions may be made for less than 1,000 limited partnership units or, if such limited partner owns less than 1,000 limited partnership units, all of the limited partnership units held by such limited partner.

	NOTE 11 – REPURCHASE PLANS
	On March 11, 2011, our Board of Trustees approved repurchase plans that enable our shareholders to sell their common shares and the partners of our operating partnership to sell their limited partnership units to us, after they have held the securities for at least one year and subject to other conditions and limitations described in the plans. Originally, the maximum amount of aggregate securities that could be repurchased under these plans was $5.0 million, and the repurchase price was fixed at $12.60 per share or unit under the plans.
	On September 7, 2012 and December 20, 2012, our Board of Trustees amended and restated our repurchase plans to increase the maximum amount that can be repurchased under the plans to $15.0 million worth of securities and increased the fixed repurchase price to $12.75 per share or unit under the plans.
	On March 28, 2013, our Board of Trustees amended our repurchase plans to increase the maximum amount that can be repurchased under the plan to $20.0 million worth of securities and increase the fixed repurchase price to $13.00 per share or unit under the plans effective May 16, 2013.
	On September 26, 2013, our Board of Trustees amended our repurchase plans to increase the maximum amount that can be repurchased under the plan to $25.0 million worth of securities and increase the fixed repurchase price to $14.00 per share or unit under the plans effective October 16, 2013.
	We may repurchase securities under the plans if we have sufficient funds to do so. Repurchases may be made quarterly, on a pro rata basis, based on receipt of written repurchase requests. The plans will terminate in the event the shares become listed on any national securities exchange, the subject of bona fide quotes on any inter-dealer quotation system or electronic communications network or are the subject of bona fide quotes in the pink sheets. Additionally, the Board, in its sole discretion, may terminate, amend or suspend the repurchase plans, either or both of them, if it determines to do so is in our best interest.

	NOTE 13 – DIVIDEND REINVESTMENT PLAN
	Our Board of Trustees approved a dividend reinvestment plan to provide existing holders of our common shares with a convenient method to purchase additional common shares without payment of brokerage commissions, fees or service charges, except brokerage commissions and taxes, if any, when common shares are sold for a participant’s account. On July 20, 2012, we registered with the Securities Exchange Commission 2.0 million common shares to be issued under the plan on Form S-3D, which automatically became effective on July 20, 2012.
	Under this plan, eligible shareholders may elect to have all or a portion (but not less than 25%) of the cash dividends they receive automatically reinvested in our common shares. If an eligible shareholder elects to reinvest cash dividends under the plan, the shareholder may also make additional automatic cash purchases of our common shares, not to exceed $5,000 per fiscal quarter or, with our prior approval, in excess of $5,000 per fiscal quarter. The purchase prices per common share under the plan equals 95% of the estimated value per common share for dividend reinvestments and equals 100% of the estimated value per common share for additional automatic cash purchases, as determined by our Board of Trustees. The estimated value per common share was $14.00 from the effective date of the plan through September 30, 2013.
	Therefore, the purchase price per common share for dividend reinvestments was $13.30 and for additional automatic cash purchases was $14.00 through September 30, 2013. The Board, in its sole discretion, may amend, suspend or terminate the plan at any time, without the consent of shareholders, upon a ten day notice to participants.
	In the nine months ended September 30, 2013, 153,000 shares were issued pursuant to dividend reinvestments and 56,000 shares were issued pursuant to additional automatic cash purchases under the plan. In the nine months ended September 30, 2012, 125,000 shares were issued pursuant to dividend reinvestments and no shares were issued pursuant to additional automatic cash purchases under the plan.

	During the first nine months of 2013 and 2012, we paid property management fees to GOLDMARK Property Management in an amount equal to 5% of rents of the properties managed. The management team of GOLDMARK Property Management includes Kenneth Regan and James Wieland.

	Board of Trustee Fees
	We paid Trustee fees of $38,000 and $41,000 during the nine month periods ended September 30, 2013 and 2012, respectively.
	Advisory Agreement
	We are an externally advised trust and as such, although we have a Board of Trustees and executive officers responsible for our management, we have no paid employees. The following is a brief description of the current fees and compensation that may be received by the Advisor under the Advisory Agreement, which must be renewed on an annual basis and approved by a majority of the independent trustees.
	Management Fee: 0.35% of our total assets, annually. Total assets are our gross assets as reflected on our consolidated financial statements, taken as of the end of the fiscal quarter last preceding the date of computation. The management fee will be payable monthly in cash or our common shares, at the option of the Advisor, not to exceed one-twelfth of 0.35% of the total assets as of the last day of the immediately preceding month. The management fee calculation is subject to quarterly and annual reconciliations. The management fee may be deferred at the option of the Advisor, without interest.
	Acquisition Fee: For its services in investigating and negotiating acquisitions of investments for us, the Advisor receives an acquisition fee of 2.5% of the purchase price of each property acquired, capped at $375,000 per acquisition.

	Disposition Fee: If the Advisor provides a substantial amount of services in the effort to sell any investment, the Advisor receives a disposition fee of 3% of the sales price of each investment. However, the disposition fee and other real estate commissions paid to unaffiliated parties cannot in the aggregate exceed the lesser of 6% of the sales price or a competitive real estate commission (which is reasonable, customary and competitive in light of the size, type and location of the property), unless approved by a majority of the trustees, including a majority of the independent trustees, if they determine the transaction to be commercially competitive, fair and reasonable to us.
	Financing Fee: 0.25% of all amounts made available to us pursuant to any loan, refinance (excluding rate and/or term modifications of an existing loan with the same lender), line of credit or other credit facility.
	Development Fee: Based on a regressive sliding scale (starting at 5% and declining to 3%) of total project costs, excluding cost of land, for development services requested by us.

	NOTE 17 – COMMITMENTS AND CONTINGENCIES
	Environmental Matters
	Federal law (and the laws of some states in which we may acquire properties) impose liability on a landowner for the presence on the premises of hazardous substances or wastes (as defined by present and future federal and state laws and regulations). This liability is without regard to fault or knowledge of the presence of such substances and may be imposed jointly and severally upon all succeeding landowners. If such hazardous substance is discovered on a property acquired by us, we could incur liability for the removal of the substances and the cleanup of the property. There can be no assurance that we would have effective remedies against prior owners of the property. In addition, we may be liable to tenants and may find it difficult or impossible to sell the property either prior to or following such a cleanup.
	Risk of Uninsured Property Losses
	We maintain property damage, fire loss, and liability insurance. However, there are certain types of losses (generally of a catastrophic nature) which may be either uninsurable or not economically insurable. Such excluded risks may include war, earthquakes, tornados, certain environmental hazards, and floods. Should such events occur, (i) we might suffer a loss of capital invested, (ii) tenants may suffer losses and may be unable to pay rent for the spaces, and (iii) we may suffer a loss of profits which might be anticipated from one or more properties.
	Investment in Unconsolidated Affiliates
	The operating partnership owns a 40.26% interest in a single asset limited liability company which owns a 144 unit multi-tenant apartment complex in Bismarck, North Dakota. The property is encumbered by a first mortgage with a balance at September 30, 2013 and December 31, 2012 of $2.4 million. We owed $966,000 and $983,000 of our respective share of the mortgage loan balance as of September 30, 2013 and December 31, 2012, respectively.
	The operating partnership is a 50% owner of Grand Forks Marketplace Retail Center through 100% ownership in a limited liability company. Grand Forks Marketplace Retail Center has approximately 183,000 square feet of commercial space in Grand Forks, North Dakota. The property is encumbered by a non-recourse first mortgage with a balance at September 30, 2013 and December 31, 2012 of $11.5 million and $11.7 million, respectively. We owed $5.7 million and $5.8 million for our respective share of the mortgage loan balance as of September 30, 2013 and December 31, 2012, respectively.
	The operating partnership owns a 2/3 interest as tenant in common in a commercial building with approximately 75,000 square feet of rental space in Fargo, North Dakota. The property is encumbered by a first mortgage with a balance at September 30, 2013 and December 31, 2012 of $7.4 million and $7.5 million, respectively.

Business Combinations [Abstract]	'
BUSINESS COMBINATIONS AND ACQUISITIONS	'
	NOTE 19 – BUSINESS COMBINATIONS AND ACQUISITIONS
	We continue to implement our strategy of acquiring properties in desired markets. It is impractical for us to obtain historical financial information on acquired properties and accordingly, proforma statements have not been presented.
	We account for our property acquisitions by allocating the purchase price of a property to the property’s assets based on management’s estimates of fair value. Techniques used to estimate fair value include an appraisal of the property by a certified independent appraiser at the time of acquisition. Significant factors included in the independent appraisal include items such as current rent schedules, occupancy levels, and discount factors. Property valuations are completed primarily using the income capitalization approach, which anticipated benefits are converted to an indication of current value.
	The total value allocable to intangible assets acquired, which consists of unamortized lease origination costs, in-place leases and tenant relationships, are allocated based on management’s evaluation of the specific characteristics of each tenant’s lease, our overall relationship with that respective tenant, growth prospects for developing new business with the tenant, the remaining term of the lease and the tenant’s credit quality, among other factors.
	The value allocable to the above or below market component of an acquired in-place lease is determined based upon the present value (using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term, and (ii) management’s estimate of rents that would be paid using fair market rates over the remaining term of the lease. The amounts allocated to above or below market leases are included in lease intangibles, net in the accompanying balance sheets and are amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases.
	We estimate the in-place lease value for each lease acquired. This fair value estimate is calculated using factors available in third party appraisals or cash flow estimates of the property prepared by our internal analysis. These estimates are based upon cash flow projections for the property, existing leases, and the current economic climate.
	Our analysis results in three discrete financial items: assets for above market leases, liabilities for below market leases, and assets for the in-place lease value. The calculation of each of these components is performed in tandem to provide a complete intangible asset value.
	Key factors considered in the calculation of fair value of both real property and intangible assets include the current market rent values, “dark” periods (building in vacant status), direct costs estimated with obtaining a new tenant, discount rates, escalation factors, standard lease terms, and tenant improvement costs.

Total consideration given for acquisitions in the first nine months of 2012 was completed through issuing approximately 290,000 limited partnership units of the operating partnership valued at $14.00 per unit for an aggregate consideration of approximately $4.1 million and cash of $9.4 million. Units issued in exchange for property are determined through a value established annually by our Board of Trustees, and reflects the fair value at the time of issuance.
The Board of Trustees, acting as general partner for the operating partnership, has determined an estimate of fair value for the limited partnership units issued in the first nine months of 2013 and 2012. In determining this value, the board relied upon their experience with, and knowledge about, our real estate portfolio and debt obligations. The board also relied on valuation methodologies that are commonly used in the real estate industry, including, among others, a discounted cash flow analysis, which projects a range of estimated future streams of cash flows reasonably likely to be generated by our portfolio of properties, discounts the projected future cash flows reasonably likely to be generated by our portfolio of properties, and discounts the projected future cash flows to a present value.
The Board also took into account the estimated value of our other assets and liabilities including a reasonable estimate of our debt obligations. Based on the results of the methodologies, the Board determined the fair value of the limited partnership units to be $14.00 per unit for the first nine months of 2013 and 2012.
As with any valuation methodology, the methodologies utilized by the Board in reaching an estimate of the value of the limited partnership units are based upon a number of estimates, assumptions, judgments or opinions that may, or may not, prove to be correct. The use of different estimates, assumptions, judgments, or opinions would likely have resulted in significantly different estimates of the value of the limited partnership units. In addition, the Board’s estimate of limited partnership unit value is not based on the fair values of our real estate, as determined by GAAP, as our book value for most real estate is based on the amortized cost of the property, subject to certain adjustments.
Furthermore, in reaching an estimate of the value of the limited partnership units, the Board did not include a liquidity discount in order to reflect the fact that the limited partnership units are not currently traded on a national securities exchange; a discount for debt that may include a prepayment obligation or a provision precluding assumption of the debt by a third party; or the costs that are likely to be incurred in connection with an appropriate exit strategy, whether that strategy might be a listing of the limited partnership units or INREIT common shares on a national securities exchange or a merger or sale of our portfolio.

Accounting Policies [Abstract]	'
Basis of presentation	'
	Basis of Presentation
	The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2012, which have previously been filed with the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted from this report on Form 10-Q pursuant to the rules and regulations of the SEC.
	The results for the interim periods shown in this report are not necessarily indicative of future financial results. The accompanying consolidated balance sheet as of September 30, 2013 and consolidated statements of operations and other comprehensive income, consolidated statements of shareholders’ equity, and consolidated statements of cash flows for the three and nine month periods ended September 30, 2013 and 2012, as applicable, have not been audited by our independent registered public accounting firm. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary to present fairly our unaudited consolidated financial position as of September 30, 2013 and our unaudited consolidated statements of operations and other comprehensive income, unaudited consolidated statements of shareholders’ equity and our unaudited consolidated statements of cash flows for the three and nine month periods ended September 30, 2013 and 2012, as applicable. These adjustments are of a normal recurring nature.
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of INREIT, INREIT Properties, LLLP, 36 single asset limited liability companies and a single asset LLC that the operating partnership is the 81.25% owner. All significant intercompany transactions and balances have been eliminated in consolidation.
	Additionally, we evaluate the need to consolidate affiliates based on standards set forth in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”). In determining whether we have a requirement to consolidate the accounts of an entity, management considers factors such as our ownership interest, our authority to make decisions and contractual and substantive participating rights of the limited partners and shareholders, as well as whether the entity is a variable interest entity (VIE) for which we have both a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and b) the obligation to absorb losses or the right to receive benefits from the VIE that could be potentially significant to the VIE.

	The consolidated financial statements include 100% of each subsidiary’s assets, liabilities, operations and cash flows, with the interests not owned by the operating partnership reflected as “noncontrolling interests in operating partnership”. All significant intercompany accounts have been eliminated in consolidation.
Investment in Unconsolidated Affiliates	'
	Investment in Unconsolidated Affiliates
	We account for unconsolidated affiliates using the equity method of accounting per guidance established under ASC 323, Investments – Equity Method and Joint Ventures (“ASC 323”). The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the affiliates’ earnings and distributions. We evaluate the carrying amount of the investments for impairment in accordance with ASC 323. Unconsolidated affiliates are reviewed for potential impairment if the carrying amount of the investment exceeds its fair value. An impairment charge is recorded when an impairment is deemed to be other-than-temporary. To determine whether impairment is other-than-temporary, we consider the financial condition of the investment. The evaluation of an investment in an affiliate for potential impairment can require our management to exercise significant judgments. No impairment losses were recorded related to the unconsolidated affiliates for the three and nine months ended September 30, 2013 and 2012.
	Investment in unconsolidated affiliates as of September 30, 2013 consists of the operating partnership’s 40.26% interest in a single asset limited liability company which owns a 144 unit residential, multi-tenant apartment complex in Bismarck, North Dakota; the operating partnership’s 100.00% interest in a single asset limited liability company which holds a 50.00% interest in a 183,000 square feet of commercial space in Grand Forks, North Dakota; and the operating partnership’s 66.67% interest as tenant in common in an office building with approximately 75,000 square feet of commercial space in Fargo, North Dakota. These investments are not consolidated as the entities do not qualify as variable interest entities and do not meet the control requirements for consolidation, as defined in ASC 810. The operating partnership and the respective affiliate partners must approve significant decisions about the applicable entities activities. As of September 30, 2013, the unconsolidated affiliates held total assets of $28.4 million and mortgage notes payable of $21.3 million.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Our cash balances are maintained in various bank deposit accounts. The bank deposit amounts in these accounts may exceed federally insured limits at various times throughout the year.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Real Estate Investments	'
	Real Estate Investments
	We account for our property acquisitions by allocating the purchase price of a property to the property’s assets based on management’s estimates of fair value. Techniques used to estimate fair value include appraisals of the properties by a certified independent appraiser at the time of acquisition.
	Furniture and fixtures are stated at cost less accumulated depreciation. All costs associated with the development and construction of real estate investments, including acquisition fees and interest, are capitalized as a cost of the property. Expenditures for renewals and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Expenditures for routine maintenance and repairs, which do not add to the value or extend useful lives, are charged to expense as incurred.
	Depreciation is provided for over the estimated useful lives of the individual assets using the straight-line method over the following estimated useful lives:
	Buildings and improvements			40 years
	Furniture and fixtures			9 years
	Depreciation expense for the three months ended September 30, 2013 and 2012 totaled $2.7 million and $2.4 million, respectively. Depreciation expense for the nine months ended September 30, 2013 and 2012 totaled $8.0 million and $7.2 million, respectively.
	The Company’s investment properties are reviewed for potential impairment at the end of each reporting period or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. At the end of each reporting period, the Company separately determines whether impairment indicators exist for each property.
	Examples of situations considered to be impairment indicators include, but are not limited to:
		•		A substantial decline or continued low occupancy rate;
		•		Continued difficulty in leasing space;
		•		Significant financial troubled tenants;
		•		a change in plan to sell a property prior to the end of its useful life or holding period;
		•		a significant decrease in market price not in line with general market trends; and
		•		any other quantitative or qualitative events or factors deemed significant by the Company’s management or board of trustees.
	If the presence of one or more impairment indicators as described above is identified at the end of the reporting period or throughout the year with respect to a property, the asset is tested for recoverability by comparing its carrying value to the estimated future undiscounted cash flows. An investment property is considered to be impaired when the estimated future undiscounted cash flows are less than its current carrying value. When performing a test for recoverability or estimating the fair value of an impaired investment property, the Company makes complex or subjective assumptions which include, but are not limited to:
		•		projected operating cash flows considering factors such as vacancy rates, rental rates, lease terms, tenant financial strength, demographics, holding period and property location;
		•		projected capital expenditures and lease origination costs;
		•		projected cash flows from the eventual disposition of an operating property using a property specific capitalization rate;
		•		comparable selling prices; and
		•		property specific discount rates for fair value estimates as necessary.
	To the extent impairment has occurred, the Company will record an impairment charge calculated as the excess of the carrying value of the asset over its fair value for impairment of investment properties. Based on evaluation, management recorded loss on impairment of property of $226,000 for the nine month period ending September 30, 2013. There have been no impairment losses during the nine month period ended September 30, 2012.
Properties Held for Sale	'
	Properties Held for Sale
	We account for our properties held for sale in accordance with ASC 360, Property, Plant and Equipment (“ASC 360”), which addresses financial accounting and reporting for the impairment or disposal of long-lived assets and requires that, in a period in which a component of an entity either has been disposed of or is classified as held for sale, the statements of operations for current and prior periods shall report the results of operations of the component as discontinued operations.
	In accordance with ASC 360, at such time as a property is held for sale, such property is carried at the lower of (1) its carrying amount or (2) fair value less costs to sell. In addition, a property being held for sale ceases to be depreciated. We classify operating properties as properties held for sale in the period in which all of the following criteria are met:
		•		management, having the authority to approve the action, commits to a plan to sell the asset;
		•		the asset is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets;
		•		an active program to locate a buyer and other actions required to complete the plan to sell the asset has been initiated;
		•		the sale of the asset is probable and the transfer of the asset is expected to qualify for recognition as a completed sale within one year;
		•		the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and
		•		given the actions required to complete the plan to sell the asset, it is unlikely that significant changes to the plan would be made or that the plan would be withdrawn.
	There was one property classified as held for sale at September 30, 2013, and no properties classified as held for sale at December 31, 2012. See Note 20.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We classify highly liquid investments with a maturity of three months or less when purchased as cash equivalents.
Receivables	'
	Receivables
	Receivables consist primarily of amounts due for rent and real estate taxes. The receivables are non-interest bearing. The carrying amount of receivables is reduced by an amount that reflects management’s best estimates of the amounts that will not be collected. As of September 30, 2013 and December 31, 2012, management determined that no allowance was necessary for uncollectible receivables.
Rental Incentives	'
	Rental Incentives
	Rental incentives consist of up-front cash payments to lessees to sign the lease. Rental incentives are amortized against rental income over the term of the lease.
Intangible Assets	'
	Intangible Assets
	Lease intangibles are a purchase price allocation recorded on property acquisition. The lease intangibles represent the estimated value of in-place leases at above or below market lease terms. Lease intangibles are amortized over the term of the related lease.
	The carrying amount of intangible assets is regularly reviewed for indicators of impairments in value. Impairment is recognized only if the carrying amount of the intangible asset is considered to be unrecoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and the estimated fair value of the asset. Based on the review, management determined that no impairment charges were necessary at September 30, 2013 or December 31, 2012.
Financing Costs	'
	Financing Costs
	Financing costs incurred in connection with financing have been capitalized and are being amortized over the life of the financing using the effective interest method.
Noncontrolling Interest	'
	Noncontrolling Interest
	Interests in the operating partnership held by limited partners are represented by limited partnership units. The operating partnership’s income is allocated to holders of units based upon the ratio of their holdings to the total units outstanding during the period. Capital contributions, distributions, syndication costs, and profits and losses are allocated to noncontrolling interests in accordance with the terms of the operating partnership agreement.
Syndication Costs	'
	Syndication Costs
	Syndication costs consist of costs paid to attorneys, accountants, and selling agents, related to the raising of capital. Syndication costs are recorded as a reduction to beneficial and noncontrolling interest.
Federal Income Taxes	'
	Federal Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code, as amended. A REIT calculates taxable income similar to other domestic corporations, with the major difference being that a REIT is entitled to a deduction for dividends paid. A REIT is generally required to distribute each year at least 90% of its taxable income. If it chooses to retain the remaining 10% of taxable income, it may do so, but it will be subject to a corporate tax on such income. REIT shareholders are taxed on REIT distributions of ordinary income in the same manner as they are taxed on other corporate distributions.
	We intend to continue to qualify as a REIT and, as such, will not be taxed on the portion of the income that is distributed to the shareholders. In addition, we intend to distribute all of our taxable income; therefore, no provisions or liabilities for income taxes have been recorded in the financial statements.
	INREIT conducts its business activity as an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) through its Operating Partnership. The Operating Partnership is organized as a limited liability limited partnership. Income or loss is allocated to the partners in accordance with the provisions of the Internal Revenue Code 704(b) and 704(c). UPREIT status allows non-recognition of gain by an owner of appreciated real estate if that owner contributes the real estate to a partnership in exchange for partnership interest. The conversion of partnership interest to shares of beneficial interest in the REIT will be a taxable event to the limited partner.
	We follow ASC Topic 740, Income Taxes, to recognize, measure, present and disclose in our consolidated financial statements uncertain tax positions that we have taken or except to take on a tax return. As of September 30, 2013 and December 31, 2012 we did not have any liabilities for uncertain tax positions that we believe should be recognized in our consolidated financial statements. We are no longer subject to Federal and State tax examinations by tax authorities for years before 2010.
	The operating partnership has elected to record related interest and penalties, if any, as income tax expense on the consolidated statements of operations and other comprehensive income.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	As of September 30, 2013, the impact of recent accounting pronouncements is not considered to be material.
Revenue Recognition	'
	Revenue Recognition
	We recognize revenue in accordance with ASC Topic 605, Revenue Recognition, or ASC Topic 605. ASC Topic 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed and determinable; and (4) collectability is reasonably assured.
	We derive over 95% of our revenues from tenant rents and other tenant-related activities. We lease multifamily residential apartments under operation leases and substantially all of our apartment leases are for a term of one year or less. Rental income and other property revenues are recorded when due from tenants and is recognized monthly as it is earned pursuant to the terms of the underlying leases. Other property revenues consist primarily of laundry, application and other fees charged to tenants.
	We lease commercial space primarily under long-term lease agreements. Commercial tenant rents include base rents, expense reimbursements (such as common area maintenance, real estate taxes and utilities), and straight-line rents. We record base rents on a straight-line basis. The monthly base rent income according to the terms of our leases is adjusted so that an average monthly rent is recorded for each tenant over the term of its lease. The straight-line rent adjustment increased revenue by $79,000 and $70,000 for the three months ended September 30, 2013 and 2012, respectively. The straight-line rent adjustment increased revenue by $304,000 and $202,000 for the nine months ended September 30, 2013 and 2012, respectively. The straight-line receivable balance included in receivables on the consolidated balance sheets as of September 30, 2013 and December 31, 2012 was $2.2 million and $1.9 million, respectively. We receive payments for expense reimbursements from substantially all our multi-tenant commercial tenants throughout the year based on estimates. Differences between estimated recoveries and the final billed amounts, which generally are immaterial, are recognized in the subsequent year.
Earnings per Common Share	'
	Earnings per Common Share
	Basic earnings per common share is computed by dividing net income available to common shareholders (the “numerator”) by the weighted average number of common shares outstanding (the “denominator”) during the period. INREIT had no dilutive potential common shares as of September 30, 2013 or 2012, and therefore, basic earnings per common share was equal to diluted earnings per common share for both periods.
	For the three months ended September 30, 2013 and 2012, INREIT’s denominators for the basic and diluted earnings per common share were approximately 5.4 million and 5.0 million, respectively. For the nine months ended September 30, 2013 and 2012, INREIT’s denominators for the basic and diluted earnings per common share were approximately 5.4 million and 4.5 million, respectively.
Reclassifications	'
	Reclassifications
	Certain amounts previously reported in our quarterly report ended September 30, 2012 have been reclassified to conform to held for sale and discontinued operations presentations in 2013.
Hedging Activities	'
	As part of our interest rate risk management strategy, we use derivative instruments to minimize significant unanticipated earnings fluctuations that may arise from rising variable interest rate costs associated with existing borrowings. To meet these objectives, we have entered into interest rate swaps for the notional amount of $1.3 million and $2.4 million to provide a fixed rate of 7.25% and 2.57%, respectively. The swaps mature in April 2020 and December 2017, respectively. The swaps were issued at approximate market terms and thus no fair value adjustment was recorded at inception.
	The carrying amount of the swaps have been adjusted to their fair values at the end of the quarter, which because of changes in forecasted levels of LIBOR resulted in reporting a liability for the fair value of the future net payments forecasted under the swaps. The interest rate swaps are accounted for as effective hedges in accordance with ASC 815-20 whereby they are recorded at fair value and changes in fair value are recorded to comprehensive income. As of September 30, 2013 and December 31, 2012, we have recorded a liability and other comprehensive loss of $347,000 and $492,000, respectively.
Fair Value Measurement	'
	ASC 820-10 established a three-level valuation hierarchy for fair value measurement. Management uses these valuation techniques to establish the fair value of the assets at the measurement date. These valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s assumptions. These two types of inputs create the following fair value hierarchy:
		•		Level 1 – Quoted prices for identical instruments in active markets;
		•		Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose significant inputs are observable;
		•		Level 3 – Instruments whose significant inputs are unobservable.
	The guidance requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.
