Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. ORGANIZATION Organization • Fifteen office buildings and two industrial properties (“Office/Industrial Properties”) which total approximately 1,464,000 rentable square feet, • Four retail shopping centers and one mixed use property (“Retail Properties”) which total approximately 228,000 rentable square feet, and • One hundred thirty-nine Model Homes owned by four affiliated limited partnerships and one limited liability company (“Residential Properties”). The Company operates in the following partnerships during the periods covered by these condensed consolidated financial statements: • The Company is the sole General Partner in two limited partnerships (NetREIT Palm Self-Storage LP and NetREIT Casa Grande LP), all with ownership in real estate income producing properties. The Company refers to these entities collectively, as the “NetREIT Partnerships”. In June 2016, the Company purchased the 5.99% outside interest in NetREIT Garden Gateway LP. • The Company is the general and limited partner in four partnerships that purchase and lease back Model Homes from developers (“Dubose Model Home Investors #201, LP”, “Dubose Model Homes Investors #202, LP”, “Dubose Model Homes Investors #203, LP” and “NetREIT Dubose Model Home REIT, LP”). The Company refers to these entities collectively, as the “Model Home Partnerships”. The Company has determined that the entities described above, where it owns less than 100%, should be included in the Company’s consolidated financial statements as the Company directs their activities and has control of these limited partnerships. The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Code, for federal income tax purposes. To qualify as a REIT, the Company must distribute annually at least 90% of adjusted taxable income, as defined in the Code, to its stockholders and satisfy certain other organizational and operating requirements. As a REIT, no provision is made for federal income taxes on income resulting from those sales of real estate investments which have or will be distributed to stockholders within the prescribed limits. However, taxes are provided for those gains which are not anticipated to be distributed to stockholders unless such gains are deferred pursuant to Section 1031. In addition, the Company is subject to a federal excise tax which equals 4% of the excess, if any, of 85% of the Company’s ordinary income plus 95% of the Company’s capital gain net income over cash distributions, as defined. The Company believes that it has met all of the REIT technical requirements for the three and nine months ended September 30, 2017 and 2016. Earnings and profits that determine the taxability of distributions to stockholders differ from net income reported for financial reporting purposes due to differences in estimated useful lives and tax deprecation methods used to compute the carrying value (basis) on the investments in properties for tax purposes, among other things. During the nine months ended September 30, 2017 and 2016, all distributions paid were considered return of capital to the stockholders as we reported a taxable net loss during the period. The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries have been assessed any significant interest or penalties for tax positions by any major tax jurisdictions.	1. ORGANIZATION AND BASIS OF PRESENTATION Organization. The following partnership activity occurred during the periods covered by these consolidated financial statements: • The Company is the sole General Partner in two consolidated limited partnerships (NetREIT Palm Self-Storage LP and NetREIT Casa Grande LP), all with ownership in real estate income producing properties.

The Company refers to these entities collectively, as the “Model Home Entities”. The Company has determined that the entities described above, where it owns less than 100%, should be included in the Company’s consolidated financial statements as the Company directs their activities and holds a non-controlling interest in these limited partnerships through NetREIT, the Parent Company.

SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation. Principles of Consolidation . The Company classifies the noncontrolling interests in the NetREIT Partnerships as part of consolidated net loss in 2016 and 2015, and includes the accumulated amount of noncontrolling interests as part of equity since inception in February 2010. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interest will be remeasured, with the gain or loss reported in the statement of operations. Management has evaluated the noncontrolling interests and determined that they do not contain any redemption features. Use of Estimates . Real Estate Assets and Lease Intangibles. The Company allocates the purchase price to tangible assets of an acquired property based on the estimated fair values of those tangible assets assuming the building was vacant. Estimates of fair value for land, building and building improvements are based on many factors including, but not limited to, comparisons to other properties sold in the same geographic area and independent third party valuations. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair values of the tangible and intangible assets and liabilities acquired. The value allocated to acquired lease intangibles is based on management’s evaluation of the specific characteristics of each tenant’s lease. Characteristics considered by management in allocating these values include the nature and extent of the existing business relationships with the 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-market 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 amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases. Amortization of above and below-market rents resulted in a net (reduction) increase in rental income of approximately $(286,000) and $44,000 for the years ended December 31, 2016 and 2015, respectively. The value of in-place leases and unamortized lease origination costs are amortized to expense over the remaining term of the respective leases, which range from less than a year to ten years. The amount allocated to acquire in-place leases is determined based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount allocated to unamortized lease origination costs is determined by what the Company would have paid to a third party to secure a new tenant reduced by the expired term of the respective lease. The amount allocated to tenant relationships is the benefit resulting from the likelihood of a tenant renewing its lease. Amortization expense related to these assets was approximately $1,224,000 and $839,000 for years ended December 31, 2016 and 2015, respectively. Discontinued Operations. Impairment of Real Estate Assets. Intangible Assets . The Company is required to perform a test for impairment of goodwill and other definite and indefinite lived assets at least annually, and more frequently as circumstances warrant. 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, no impairment was deemed to exist at December 31, 2016 and 2015. Depreciation and Amortization. Cash and Cash Equivalents. Restricted Cash. Tenant Receivables. Deferred Leasing Costs. Deferred Financing Costs. Income Taxes. We have elected to treat such subsidiaries as taxable REIT subsidiaries (a “TRS”) for federal income tax purposes. Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants, and holding assets that we cannot hold directly. A TRS is subject to federal and state income taxes. The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries have been assessed any significant interest or penalties for tax positions by any major tax jurisdictions. Fair Value Measurements. Level 1—Quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2—Inputs other than quoted process that are observable for the asset or liability, either directly or indirectly. Level 3—Unobservable inputs for the asset or liability. Fair value is defined as the price at which an asset or liability is exchanged between market participants in an orderly transaction at the reporting date. Cash equivalents, mortgage notes receivable, accounts receivable and payables and accrued liabilities all approximate fair value due to their short term nature. During the year ended December 31, 2016, the Company measured the fair value of two of its real estate properties on a nonrecurring basis using Level 3 inputs. The Company estimated the fair value for these impaired real estate assets held for investment based on an estimated sales price, less estimated costs to sell. Management believes that the recorded and fair values of notes payable are approximately the carrying value of December 31, 2016 and 2015. Sales of Real Estate Assets . a. The buyer is independent of the seller; b. Collection of the sales price is reasonably assured; and c. The seller is not required to support the operations of the property or its related obligations to an extent greater than its proportionate interest. Gains relating to transactions which do not meet the criteria for full accrual method of accounting are deferred and recognized when the full accrual method of accounting criteria are met or by using the installment or deposit methods of profit recognition, as appropriate in the circumstances. Revenue Recognition. a. Persuasive evidence of an arrangement exists; b. Delivery has occurred or services have been rendered; c. The amount is fixed or determinable; and d. The collectability of the amount is reasonably assured. Rental revenue is recognized on a straight-line basis over the term of the related lease. Estimated recoveries from certain tenants for their pro rata share of real estate taxes, insurance and other operating expenses are recognized as revenues in the period the applicable expenses are incurred or as specified in the leases. Other tenants pay a fixed rate and these tenant recoveries are recognized as revenue on a straight-line basis over the term of the related leases. Certain of the Company’s leases currently contain rental increases at specified intervals. The Company records as an asset, and include in revenues, deferred rent receivable that will be received if the tenant makes all rent payments required through the expiration of the initial term of the lease. Deferred rent receivable in the accompanying balance sheets includes the cumulative difference between rental revenue recorded on a straight-line basis and rents received from the tenants in accordance with the lease terms. Accordingly, Management determines to what extent the deferred rent receivable applicable to each specific tenant is collectible. The Company reviews material deferred rent receivable and takes into consideration the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. In the event that the collectability of deferred rent with respect to any given tenant is in doubt, we record an increase in the allowance for uncollectible accounts, the Company records a direct write-off of the specific rent receivable. No such reserves related to deferred rent receivables have been recorded as of December 31, 2016 and 2015. Loss per Common Share. Basic and diluted net loss per share are equivalent because the Company has incurred a net loss in all periods presented causing any potentially dilutive securities to be anti-dilutive. Dilutive securities include non-vested restricted shares issued under the Company’s share-based incentive plan, shares issuable under certain of the Company’s partnership arrangements and (for 2013) shares issuable under stock purchase warrants. The calculation of net loss per share excludes dilutive securities totaling 643,510 and 722,019 shares for the years ended December 31, 2016 and 2015, respectively. Subsequent Events. Reclassifications. Recently Issued Accounting Pronouncements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends Accounting Standards Codification (“ASC”) Topic 718, Compensation—Stock Compensation. This pronouncement simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Restricted Cash. This pronouncement will require companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The pronouncement will require a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalents balances will be required to disclose the nature of the restrictions. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. As of December 31, 2016 and 2015, we had $4.3 million and $6.8 million of restricted cash, respectively, in our consolidated balance sheets. Upon adoption of this ASU, restricted cash balances will be included along with cash and cash equivalents as of the end of period and beginning of period, respectively, in our consolidated statement of cash flows for all periods presented; separate line items showing changes in restricted cash balances will be eliminated from our consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations. This pronouncement clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted for transactions that have not been reported in previously issued (or available to be issued) financial statements.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Incentive Plan	12. SHARE-BASED INCENTIVE PLAN The Company maintains a restricted stock incentive plan for the purpose of attracting and retaining officers, key employees and non-employee board members. Share awards vest in equal annual instalments over a three to ten year period from date of issuance. Non-vested shares have voting rights and are eligible for any dividends paid to common shares. The Company recognized compensation cost for these fixed awards over the service vesting period, which represents the requisite service period, using the straight-line method. The value of non-vested shares was calculated based on the offering price of the shares in the most recent private placement offering of $10.00, adjusted for stock dividends since granted and assumed selling costs (currently $8.60), which management believes approximates fair market value as of the date of grant. A summary of the activity for the Company’s restricted shares was as follows: Outstanding shares: Common Shares Balance at December 31, 2015 120,360 Granted 88,768 Vested (60,249 ) Balance at December 31, 2016 148,879 The non-vested restricted shares outstanding as of December 31, 2016 will vest over the next one to ten years. The value of non-vested restricted stock granted for the years ended December 31, 2016 and 2015 was approximately $1,280,000 and $1,036,000, respectively. Share-based compensation expense for the years ended December 31, 2016 and 2015 was approximately $520,000 and $465,000, respectively.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends Accounting Standards Codification (“ASC”) Topic 718, Compensation—Stock Compensation. This pronouncement simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Restricted Cash. This pronouncement will require companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The pronouncement will require a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalents balances will be required to disclose the nature of the restrictions. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. As of December 31, 2016 and 2015, we had $4.3 million and $6.8 million of restricted cash, respectively, in our consolidated balance sheets. Upon adoption of this ASU, restricted cash balances will be included along with cash and cash equivalents as of the end of period and beginning of period, respectively, in our consolidated statement of cash flows for all periods presented; separate line items showing changes in restricted cash balances will be eliminated from our consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations. This pronouncement clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted for transactions that have not been reported in previously issued (or available to be issued) financial statements.
Real Estate Asset Acquisitions		Real Estate Assets and Lease Intangibles. The Company allocates the purchase price to tangible assets of an acquired property based on the estimated fair values of those tangible assets assuming the building was vacant. Estimates of fair value for land, building and building improvements are based on many factors including, but not limited to, comparisons to other properties sold in the same geographic area and independent third party valuations. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair values of the tangible and intangible assets and liabilities acquired. The value allocated to acquired lease intangibles is based on management’s evaluation of the specific characteristics of each tenant’s lease. Characteristics considered by management in allocating these values include the nature and extent of the existing business relationships with the 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-market 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 amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases. Amortization of above and below-market rents resulted in a net (reduction) increase in rental income of approximately $(286,000) and $44,000 for the years ended December 31, 2016 and 2015, respectively. The value of in-place leases and unamortized lease origination costs are amortized to expense over the remaining term of the respective leases, which range from less than a year to ten years. The amount allocated to acquire in-place leases is determined based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount allocated to unamortized lease origination costs is determined by what the Company would have paid to a third party to secure a new tenant reduced by the expired term of the respective lease. The amount allocated to tenant relationships is the benefit resulting from the likelihood of a tenant renewing its lease. Amortization expense related to these assets was approximately $1,224,000 and $839,000 for years ended December 31, 2016 and 2015, respectively.
Discontinued Operations		Discontinued Operations.
Intangible Assets		Intangible Assets . The Company is required to perform a test for impairment of goodwill and other definite and indefinite lived assets at least annually, and more frequently as circumstances warrant. 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, no impairment was deemed to exist at December 31, 2016 and 2015.

Income Taxes		Income Taxes. We have elected to treat such subsidiaries as taxable REIT subsidiaries (a “TRS”) for federal income tax purposes. Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants, and holding assets that we cannot hold directly. A TRS is subject to federal and state income taxes. The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries have been assessed any significant interest or penalties for tax positions by any major tax jurisdictions.
Fair Value Measurements		Fair Value Measurements. Level 1—Quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2—Inputs other than quoted process that are observable for the asset or liability, either directly or indirectly. Level 3—Unobservable inputs for the asset or liability. Fair value is defined as the price at which an asset or liability is exchanged between market participants in an orderly transaction at the reporting date. Cash equivalents, mortgage notes receivable, accounts receivable and payables and accrued liabilities all approximate fair value due to their short term nature. During the year ended December 31, 2016, the Company measured the fair value of two of its real estate properties on a nonrecurring basis using Level 3 inputs. The Company estimated the fair value for these impaired real estate assets held for investment based on an estimated sales price, less estimated costs to sell. Management believes that the recorded and fair values of notes payable are approximately the carrying value of December 31, 2016 and 2015.
Sales of Real Estate Assets		Sales of Real Estate Assets . a. The buyer is independent of the seller; b. Collection of the sales price is reasonably assured; and c. The seller is not required to support the operations of the property or its related obligations to an extent greater than its proportionate interest. Gains relating to transactions which do not meet the criteria for full accrual method of accounting are deferred and recognized when the full accrual method of accounting criteria are met or by using the installment or deposit methods of profit recognition, as appropriate in the circumstances.
Revenue Recognition		Revenue Recognition. a. Persuasive evidence of an arrangement exists; b. Delivery has occurred or services have been rendered; c. The amount is fixed or determinable; and d. The collectability of the amount is reasonably assured. Rental revenue is recognized on a straight-line basis over the term of the related lease. Estimated recoveries from certain tenants for their pro rata share of real estate taxes, insurance and other operating expenses are recognized as revenues in the period the applicable expenses are incurred or as specified in the leases. Other tenants pay a fixed rate and these tenant recoveries are recognized as revenue on a straight-line basis over the term of the related leases. Certain of the Company’s leases currently contain rental increases at specified intervals. The Company records as an asset, and include in revenues, deferred rent receivable that will be received if the tenant makes all rent payments required through the expiration of the initial term of the lease. Deferred rent receivable in the accompanying balance sheets includes the cumulative difference between rental revenue recorded on a straight-line basis and rents received from the tenants in accordance with the lease terms. Accordingly, Management determines to what extent the deferred rent receivable applicable to each specific tenant is collectible. The Company reviews material deferred rent receivable and takes into consideration the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. In the event that the collectability of deferred rent with respect to any given tenant is in doubt, we record an increase in the allowance for uncollectible accounts, the Company records a direct write-off of the specific rent receivable. No such reserves related to deferred rent receivables have been recorded as of December 31, 2016 and 2015.
Loss per Common Share		Loss per Common Share. Basic and diluted net loss per share are equivalent because the Company has incurred a net loss in all periods presented causing any potentially dilutive securities to be anti-dilutive. Dilutive securities include non-vested restricted shares issued under the Company’s share-based incentive plan, shares issuable under certain of the Company’s partnership arrangements and (for 2013) shares issuable under stock purchase warrants. The calculation of net loss per share excludes dilutive securities totaling 643,510 and 722,019 shares for the years ended December 31, 2016 and 2015, respectively.
