Nature of Business [Text Block]	'
	A. Nature of Business
	United Development Funding III, L.P. (which may be referred to as the “Partnership,” “we,” “us,” “our” or “UDF III”) was organized on June 13, 2005 as a Delaware limited partnership.  Our principal business purpose is to originate, acquire, service, and otherwise manage, either alone or in association with others, a portfolio of mortgage loans that are secured by real property or equity interests that hold real property already subject to other mortgages (including mortgage loans that are not first in priority and participation interests in mortgage loans) and to issue or acquire an interest in credit enhancements for the benefit of borrowers, such as guarantees or letters of credit.  Our offices are located in Grapevine, Texas.
	Our general partner is UMTH Land Development, L.P. (“Land Development”), a Delaware limited partnership that is responsible for our overall management, conduct, and operation.  Our general partner has authority to act on our behalf in all matters respecting us, our business and our property.  Our limited partners take no part in the management of our business or transact any business for us and have no power to sign for or bind us; provided, however, that our limited partners, by a majority vote and without the concurrence of our general partner, have the right to:  (a) amend the Second Amended and Restated Agreement of Limited Partnership governing the Partnership, as amended (the “Partnership Agreement”), (b) dissolve the Partnership, (c) remove our general partner or any successor general partner, (d) elect a new general partner, and (e) approve or disapprove a transaction entailing the sale of all or substantially all of the real properties acquired by the Partnership.
	UMT Holdings, L.P. (“UMT Holdings”), a Delaware limited partnership, holds 99.9% of the limited partnership interests in our general partner. UMT Services, Inc. (“UMT Services”), a Delaware corporation, owns the remaining 0.1% of the limited partnership interests in our general partner and serves as its general partner.  Land Development has been engaged to provide asset management services for four investment partnerships (United Development Funding, L.P. (“UDF I”), United Development Funding II, L.P., United Development Funding Land Opportunity Fund, L.P. (“UDF LOF”), all Delaware limited partnerships, and UDF TX Two, L.P., a Texas limited partnership), and United Development Funding IV, a Maryland real estate investment trust (“UDF IV”).  Land Development also holds a 99.9% partnership interest in UMTHLD FLF I, L.P. and UMTHLD FLF II, L.P., both Texas limited partnerships, and United Development Funding X, L.P., a Delaware limited partnership, with the remaining 0.1% interest owned by UMT Services.  In addition, Land Development owns 100% of the interests in UDF Land GP, LLC, which serves as the general partner of the general partner of UDF LOF.  See Note K for discussion of related party transactions.

Accounting Policies [Abstract]	'
Significant Accounting Policies [Text Block]	'
	B. Summary of Significant Accounting Policies
	A summary of our significant accounting policies consistently applied in the preparation of the accompanying financial statements follows:
	Basis of Presentation
	The accompanying unaudited financial statements were prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information, with the instructions to Form 10-Q and with Regulation S-X.  They do not include all information and footnotes required by GAAP for complete financial statements.  However, except as disclosed herein, there has been no material change to the information disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the Securities and Exchange Commission  on April 1, 2013 (the “Annual Report”).  The accompanying interim unaudited financial statements should be read in conjunction with the financial statements filed in our Annual Report.  In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting solely of normal recurring adjustments, considered necessary to present fairly our financial position as of September 30, 2013, operating results for the three and nine months ended September 30, 2013 and 2012, and cash flows for the nine months ended September 30, 2013 and 2012.  Operating results and cash flows for the nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	Mortgage Notes Receivable and Mortgage Notes Receivable – Related Parties
	Mortgage notes receivable and mortgage notes receivable – related parties are recorded at the lower of cost or estimated net realizable value.  The mortgage investments are collateralized by land and related improvements to residential property owned by the borrowers and/or the ownership interests of the borrower. Currently, the mortgage investments have terms ranging from 5 to 36 months.  None of such mortgages are insured or guaranteed by a federally owned or guaranteed mortgage agency.  We originate and/or acquire all mortgage notes receivable and intend to hold the mortgage notes receivable for the life of the notes.
	Participation Interest – Related Party
	Participation interest – related party is recorded at the lower of cost or net realizable value.  Participation interest – related party represents an Economic Interest Participation Agreement with United Mortgage Trust, a real estate investment trust organized under the laws of the state of Maryland (“UMT”), pursuant to which we purchased (i) an economic interest in an $82.0 million revolving credit facility (the “UMT Loan”) from UMT to UDF I, and (ii) a purchase option to acquire a full ownership participation interest in the UMT Loan. See Note K, “Related Party Transactions” for further details.  Our general partner serves as the asset manager for UDF I.  An affiliate of our general partner serves as the advisor to UMT.
	Allowance for Loan Losses
	The allowance for loan losses is our estimate of incurred losses in our portfolio of mortgage notes receivable, mortgage notes receivable – related parties and participation interest – related party.  We periodically perform a detailed review of our portfolio of mortgage notes and other loans to determine if impairment has occurred and to assess the adequacy of the allowance for loan losses.  Our review consists of evaluating economic conditions, the estimated value of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral, and other relevant factors. This review is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
	In reviewing our portfolio, we use cash flow estimates from the disposition of finished lots, paper lots (residential lots shown on a plat that has been accepted by the city or county, but which is currently undeveloped or under development) and undeveloped land as well as cash flow received from the issuance of bonds from municipal reimbursement districts.  These estimates are based on current market metrics, including, without limitation, the supply of finished lots, paper lots and undeveloped land, the supply of homes and the rate and price at which land and homes are sold, historic levels and trends, executed purchase contracts, appraisals and discussions with third party market analysts and participants, including homebuilders. We base our valuations on current and historic market trends on our analysis of market events and conditions, including activity within our portfolio, as well as the analysis of third-party services such as Metrostudy and Residential Strategies, Inc. Cash flow forecasts also are based on executed purchase contracts which provide base prices, escalation rates, and absorption rates on an individual project basis. For projects deemed to have an extended time horizon for disposition, we consider third-party appraisals to provide a valuation in accordance with guidelines set forth in the Uniform Standards of Professional Appraisal Practice. In addition to cash flows from the disposition of property, cost analysis is performed based on estimates of development and senior financing expenditures provided by developers and independent professionals on a project-by-project basis. These amounts are reconciled with our best estimates to establish the net realizable value of the portfolio.
	We charge additions to the allowance for loan losses to current period earnings through a provision for loan losses. Amounts determined to be uncollectible are charged directly against, or “charged off,” and decrease the allowance for loan losses, while amounts recovered on previously charged off accounts increase the allowance.
	Revenue Recognition
	Interest income on mortgage notes receivable, mortgage notes receivable – related parties and participation interest – related party is recognized over the life of the loan and recorded on the accrual basis.  Income recognition is suspended for loans at the date at which, in the opinion of management, a full recovery of income and principal becomes more likely than not, but is no longer probable, based upon our review of economic conditions, the estimated value of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors. Income recognition is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Any payments received on loans classified as non-accrual status are typically applied first to outstanding loan amounts and then to the recovery of lost interest.  As of both September 30, 2013 and December 31, 2012, we were suspending income recognition on 2 mortgage notes receivable with an aggregate unpaid principal balance of approximately $2.2 million.
	We generate mortgage and transaction service revenues and mortgage and transaction service revenues – related parties by originating and acquiring mortgage notes receivable and other loans.  In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 310-20, Receivables – Nonrefundable Fees and Other Costs, we defer recognition of income from nonrefundable commitment fees paid by the borrowers and recognize such amount on a straight-line basis over the expected life of such notes.  In addition, credit enhancement fee income is generated by fees charged to parties for credit enhancements provided to lenders by the Partnership on behalf of the parties.  Income related to credit enhancements is earned as fees are paid, based on the terms of the credit enhancement agreement.  As of September 30, 2013, the Partnership was providing 10 credit enhancements to related parties (see Note K for further discussion).
	The Partnership also expenses acquisition and origination fees (“Placement Fees”) paid to the general partner to provide for processing and origination costs (including, but not limited to, legal fees and expenses, travel and communications expenses, costs of appraisals, accounting fees and expenses, and title insurance funded by us) associated with mortgage notes receivable or participation interest held by the Partnership on a straight-line basis.  As of September 30, 2013 and December 31, 2012, approximately $1.9 million and $2.5 million, respectively, of such net deferred fees are included in mortgage notes receivable. Approximately $530,000 and $698,000 of net deferred fees are included in mortgage notes receivable – related parties as of September 30, 2013 and December 31, 2012, respectively.  As of September 30, 2013 and December 31, 2012, approximately $371,000 and $489,000, respectively, of deferred fees are included in participation interest – related party.  See Note K, “Related Party Transactions” for further details.
	Cash Flow Distributions
	Cash available for distributions represents the cash funds received by us from operations (other than net proceeds from a capital transaction) that produce proceeds from (i) the repayment of principal or prepayment of a mortgage to the extent classified as a return of capital for federal income tax purposes, (ii) the foreclosure, sale, exchange, condemnation, eminent domain taking or other disposition of a mortgage loan or of a property subject to a mortgage, or (iii) insurance or a guarantee with respect to a mortgage, including, without limitation, interest, points, revenue participations in property appreciation and interest or dividends from interim investments or proceeds from borrowings, if appropriate, less all cash used to pay Partnership expenses and debt payments and amounts set aside to create a retained earnings reserve (currently at 9.5% of our net income; the retained earnings reserve is intended to recover some of the organization and offering expenses incurred in connection with our public offering of our units of limited partnership interest).  Our general partner receives a monthly distribution for promotional and carried interest from the cash available for distributions, in addition to the payments made to our general partner and related parties.  See Note K for further discussion of related party transactions.
	A “carried interest” is an equity interest in us to participate in all distributions, other than distributions attributable to our general partner’s promotional interest, of cash available for distribution and net proceeds from a capital transaction that are distributable under the distribution priority for net proceeds from a capital transaction described below.  If our general partner enters into commitments to investments in mortgages in excess of 82% of the gross proceeds of our public offering of our units of limited partnership interest, our general partner will be entitled to a carried interest equal to (a) 1% for the first 2.5% of commitments to investments in mortgages above 82% of the gross proceeds of our initial public offering, as declared effective on May 15, 2006 pursuant to a Registration Statement on Form S-11 (File No. 333-127891) under the Securities Act of 1933, as amended (the “Offering”) (or if commitments to investments in mortgages are above 82% but no more than 84.5%, 1% multiplied by the fractional amount of commitments to investments in mortgages above 82%), (b) 1% for the next 2% of additional commitments to investments in mortgages above 84.5% of the gross proceeds of the Offering (or if commitments to investments in mortgages are above 84.5% but no more than 86.5%, 1% multiplied by the fractional amount of commitments to investments in mortgages above 84.5%) and (c) 1% for each additional 1% of additional commitments to investments in mortgages above 86.5% of the gross proceeds of the Offering (or a fractional percentage equal to the fractional amount of any 1% of additional commitments to investments in mortgages). By way of illustration, if 85.5% of the gross proceeds of the Offering are committed to investments in mortgages, then our general partner would be entitled to a carried interest of 1.5% (1% for the first 2.5% of commitments to investments in mortgages above 82% of the gross proceeds of the Offering and 0.5% for the next 1% of additional commitments to investments in mortgages above 84.5% of the gross proceeds of the Offering) of any amount otherwise distributable to the limited partners after deduction of any promotional interest payable to our general partner.
	In order for proceeds to be considered “committed” for purposes of calculation and payment of a carried interest, we must be obligated by contract or other binding agreement to invest such proceeds in mortgages, to the exclusion of any other use for such proceeds or no use at all.
	“Investments in mortgages” are the aggregate amount of capital contributions from investors used by us to make or invest in mortgage loans or the amount actually paid or allocated to the purchase of mortgages, working capital reserves (but excluding working capital reserves in excess of 3% of the aggregate capital contributions) and other cash payments such as interest and taxes but excluding our organization and offering expenses, selling commissions, wholesaling fees, marketing support fees, due diligence fees, acquisition and origination fees, and any other front-end fees.
	Our general partner’s “promotional interest” is our general partner’s right to receive:
	⋅      prior to the return to the limited partners of all of their capital contributions plus an 8% per annum, non-compounding, cumulative return on their unreturned capital contributions, 10% of all cash available for distribution;
	⋅      following the return to the limited partners of all of their capital contributions plus an 8% per annum, non-compounding, cumulative return on their unreturned capital contributions, 15% of all cash available for distribution; and
	⋅      following the return to the limited partners of all of their capital contributions plus an 8% per annum, non-compounding, cumulative return on their unreturned capital contributions, 15% of all net proceeds from a capital transaction.
	Monthly distributions are currently paid to our limited partners at a 9.75% annualized return, assuming a purchase price of $20.00 per unit, on a pro rata basis based on the number of days in the Partnership.  Retained earnings would contain a surplus if the cash available for distributions less the 9.5% reserve exceeded the monthly distribution to the general and limited partners.  Retained earnings would contain a deficit if cash available for distributions less the 9.5% reserve is less than the monthly distribution to general and limited partners.  It is the intent of management to monitor and distribute such surplus, if any, on an annual basis.
	The chart below summarizes the approximate aggregate amount of distributions to our general partner and limited partners and the retained earnings deficit as of September 30, 2013 and December 31, 2012:
		As of September 30,				As of December 31,
		2013				2012
	General Partner	$	23,143,000	-1		$	19,767,000	-2
	Limited Partners		188,341,000	-3			160,674,000	-4
	Retained Earnings Reserve		11,957,000				6,880,000
	Retained Earnings Deficit		-9,597,000				-11,211,000
	(1)   approximately $23.1 million paid in cash and $24,000 has been declared, but not paid.
	(2)   approximately $19.8 million paid in cash.
	(3)   approximately $127.5 million paid in cash and approximately $60.8 million reinvested in 3,041,059 units of limited partnership interest under our DRIP and Secondary DRIP, each as defined in Note C below.
	(4)   approximately $107.4 million paid in cash and approximately $53.3 million reinvested in 2,663,191 units of limited partnership interest under our DRIP and Secondary DRIP, each as defined in Note C below.
	The chart below summarizes the payment of related party fees and reimbursements associated with the Offering and origination and management of assets, including the distributions to our general partner described above, and general and administrative – related parties expenses for the nine months ended September 30, 2013 and 2012.  We believe that these fees and reimbursements are reasonable and customary for comparable mortgage programs.
		For the Nine Months Ended September 30,

	Payments to General Partner and Related Parties	$	4,600,000		$	5,631,000
	Total General and Administrative Expenses to General Partner and		2,082,000			2,065,000
	Related Parties
	Fair Value of Financial Instruments
	In accordance with the reporting requirements of FASB ASC 825-10, Financial Instruments-Fair Value, we calculate the fair value of our assets and liabilities that qualify as financial instruments under this statement and include this additional information in the notes to the financial statements when the fair value is different than the carrying value of those financial instruments.  The estimated fair value of restricted cash, accrued interest receivable, accrued interest receivable – related parties, accounts receivable – related parties, accounts payable, accrued liabilities, and accrued liabilities – related parties approximates the carrying amounts due to the relatively short maturity of these instruments. The estimated fair value of mortgage notes receivable, mortgage notes receivable – related parties, participation interest – related party, and line-of-credit approximates the carrying amount since they bear interest at the market rate.
	Guarantees
	The Partnership from time to time enters into guarantees of debtors’ or affiliates’ borrowings and provides credit enhancements for the benefit of senior lenders in connection with the Partnership’s debtors and investments in partnerships (collectively referred to as “guarantees”), and accounts for such guarantees in accordance with FASB ASC 460-10, Guarantees.

	C. Registration Statement
	On May 15, 2006, the Offering pursuant to a Registration Statement on Form S-11 (File No. 333-127891) was declared effective under the Securities Act of 1933, as amended.  The Offering, at the time of such effectiveness, covered up to 12,500,000 units of limited partnership interest at a price of $20.00 per unit (the “Primary Offering”) and up to 5,000,000 units of limited partnership interest to be issued pursuant to our distribution reinvestment plan (the “DRIP”) at a price of $20.00 per unit.  We had the right to reallocate the units of limited partnership interest we were offering between the Primary Offering and our DRIP, and pursuant to Supplement No. 8 to our prospectus regarding the Offering, which was filed with the Securities and Exchange Commission on September 4, 2008, we reallocated the units being offered such that 16,250,000 units were offered pursuant to the Primary Offering and 1,250,000 units were offered pursuant to the DRIP.  Pursuant to Supplement No. 11 to our prospectus regarding the Offering, which was filed with the Securities and Exchange Commission on March 6, 2009, we further reallocated the units being offered such that 16,500,000 units were offered pursuant to the Primary Offering and 1,000,000 units were offered pursuant to the DRIP.  The Primary Offering was terminated on April 23, 2009.  We extended the offering of our units of limited partnership interest pursuant to our DRIP until the earlier of the sale of all units of limited partnership interest being offered pursuant to our DRIP or May 15, 2010; provided, however, that our general partner was permitted to terminate the offering of units pursuant to our DRIP at any earlier time.
	On June 12, 2009, we registered 5,000,000 additional units to be offered at the Estimated Unit Value (as defined in Note H below) pursuant to an Amended and Restated Distribution Reinvestment Plan in a Registration Statement on Form S-3 (File No. 333-159939) (“Secondary DRIP”).  As such, we ceased offering units under the DRIP as of July 21, 2009 and concurrently commenced our offering of units pursuant to the Secondary DRIP, which is currently ongoing. On September 6, 2013, the general partner determined the most recent Estimated Unit Value to be $20.00 per unit, which will be used as the Estimated Unit Value until such time as our general partner provides a new estimated value of the Partnership’s units of limited partnership interest.

	Of these 9 loans, as of December 31, 2012, full collectability was considered probable for 7 loans with an aggregate unpaid principal balance of approximately $109.6 million and full collectability was considered more likely than not, but not probable, for 2 loans with an aggregate unpaid principal balance of approximately $2.2 million.  In March 2013, we amended one of the loans to a non-affiliated third party that had matured as of December 31, 2012 for which full collectability was considered probable as of December 31, 2012. The amendment increased the commitment amount from approximately $77.0 million to $84.5 million and extended the maturity date of the note to March 31, 2014.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.

A loan is placed on non-accrual status and income recognition is suspended at the date at which, in the opinion of management, a full recovery of income and principal becomes more likely than not, but is no longer probable, based upon our review of economic conditions, the estimated value of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors. Income recognition is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Any payments received on loans classified as non-accrual status are typically applied first to outstanding loan amounts and then to the recovery of lost interest.  As of both September 30, 2013 and December 31, 2012, we were suspending income recognition on 2 mortgage notes receivable with an aggregate unpaid principal balance of approximately $2.2 million.
Loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is generally evaluated on an individual loan basis for each loan in the portfolio. If an individual loan is considered impaired, a specific valuation allowance may be allocated, if necessary, so that the individual loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from collateral. Loans that are not individually considered impaired are collectively and qualitatively measured as a portfolio for general valuation allowance. In reviewing our portfolio for this valuation analysis, we use cash flow estimates from the disposition of finished lots, paper lots (residential lots shown on a plat that has been accepted by the city or county, but which is currently undeveloped or under development) and undeveloped land as well as cash flow received from the issuance of bonds from municipal reimbursement districts. These estimates are based on current market metrics, including, without limitation, the supply of finished lots, paper lots and undeveloped land, the supply of homes and the rate and price at which land and homes are sold, historic levels and trends, executed purchase contracts, appraisals and discussions with third party market analysts and participants, including homebuilders. We base our valuations on current and historic market trends on our analysis of market events and conditions, including activity within our portfolio, as well as the analysis of third-party services such as Metrostudy and Residential Strategies, Inc. Cash flow forecasts also are based on executed purchase contracts which provide base prices, escalation rates, and absorption rates on an individual project basis. For projects deemed to have an extended time horizon for disposition, we consider third-party appraisals to provide a valuation in accordance with guidelines set forth in the Uniform Standards of Professional Appraisal Practice. In addition to cash flows from the disposition of property, cost analysis is performed based on estimates of development and senior financing expenditures provided by developers and independent professionals on a project-by-project basis. These amounts are reconciled with our best estimates to establish the net realizable value of the portfolio.
Interest is recognized on an accrual basis for impaired loans in which the collectability of the unpaid principal amount is deemed probable. Any payments received on such loans are first applied to outstanding accrued interest receivable and then to outstanding unpaid principal balance. Unpaid principal balance is materially the same as recorded investments.  Any payments received on impaired loans in which the collectability of the unpaid principal amount is less than probable are typically applied to outstanding unpaid principal and then to the recovery of lost interest on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible.
As of September 30, 2013, we had 8 mortgage notes receivable with an aggregate unpaid principal balance of approximately $39.0 million that were considered impaired due to the loans remaining outstanding beyond the contractual term of the loan agreement.  Of these 8 loans, full collectability is considered probable for 6 loans with an aggregate unpaid principal balance of approximately $36.8 million and full collectability is considered more likely than not, but not probable, for 2 loans with an aggregate unpaid principal balance of approximately $2.2 million.  As of December 31, 2012, we had 9 mortgage notes receivable with an aggregate unpaid principal balance of approximately $111.8 million.  Of these loans, 8 loans, with an aggregate unpaid principal balance of approximately $34.8 million, were considered impaired due to the loans remaining outstanding beyond the contractual term of the loan agreement, and 1 loan, with an unpaid principal balance of approximately $77.0 million, was not considered impaired as the note was amended during March 2013 to extend the maturity date to March 31, 2014.  Of these 9 loans, full collectability was considered probable for 7 loans with an aggregate unpaid principal balance of approximately $109.6 million and full collectability was considered more likely than not, but not probable, for 2 loans with an aggregate unpaid principal balance of approximately $2.2 million.  For the nine months ended September 30, 2013 and the year ended December 31, 2012, the average outstanding aggregate unpaid principal balance for impaired loans was approximately $36.7 million and $36.2 million, respectively. For the three months ended September 30, 2013 and 2012, we recognized approximately $1.4 million and $1.2 million, respectively, of interest income related to impaired loans. For each of the nine months ended September 30, 2013 and 2012, we recognized approximately $4.1 million of interest income related to impaired loans.  For the three and nine months ended September 30, 2013 and 2012, we did not recognize any cash basis interest income related to impaired loans. No specific allowance was allocated to impaired loans as of September 30, 2013 and December 31, 2012.
As part of the ongoing monitoring of the credit quality of the loan portfolio, we periodically, no less than quarterly, perform a detailed review of our portfolio of mortgage notes and other loans. The following is a general description of the credit levels used:
Level 1 – Full collectability of loans in this category is considered probable.
Level 2 – Full collectability of loans in this category is deemed more likely than not, but not probable, based upon our review of economic conditions, the estimated value of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors. Interest income is suspended on Level 2 loans.
Level 3 – For loans in this category, it is probable that we will be unable to collect all amounts due.
As of September 30, 2013 and December 31, 2012, our loans were classified as follows:
	September 30, 2013		December 31, 2012
Level 1	$	366,893,000	$	361,923,000
Level 2		2,199,000		2,178,000
Level 3		-		-
Total	$	369,092,000	$	364,101,000
The allowance for loan losses is our estimate of incurred losses in our portfolio of mortgage notes receivable, mortgage notes receivable – related parties and participation interest – related party.  We periodically perform a detailed review of our portfolio of mortgage notes and other loans to determine if impairment has occurred and to assess the adequacy of the allowance for loan losses.  We charge additions to the allowance for loan losses to current period earnings through a provision for loan losses.  Amounts determined to be uncollectible are charged directly against (and decrease) the allowance for loan losses (“charged off”), while amounts recovered on previously charged off amounts increase the allowance for loan losses.  The following table summarizes the change in the reserve for loan losses during the nine months ended September 30, 2013 and the year ended December 31, 2012, which is offset against mortgage notes receivable:
	For the Nine Months		For the Year Ended

Charge-offs		-		-
Balance, end of period	$	17,080,000	$	16,644,000
We have adopted the provisions of ASU 2011-02, A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring.  In accordance with ASU 2011-02, the restructuring of a loan is considered a “troubled debt restructuring” if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses.  As of September 30, 2013 and December 31, 2012, we have no loan modifications that are classified as troubled debt restructurings.

	E. Line-of-Credit
	On September 21, 2009, during the credit crisis in which financial institutions severely reduced the number of loans made to entities involved in real estate, the Partnership entered into a Loan and Security Agreement (the “Loan Agreement”) with Wesley J. Brockhoeft, an unaffiliated individual (the “Lender”), pursuant to which the Lender provided the Partnership with a revolving credit facility in the maximum principal amount of $15.0 million (the “Brockhoeft Credit Facility”). The interest rate on the Brockhoeft Credit Facility is equal to 10% per annum.  Accrued interest on the outstanding principal amount of the Brockhoeft Credit Facility is payable monthly.   The Brockhoeft Credit Facility is secured by a first priority lien on all of the Partnership’s existing and future assets.  In consideration of the Lender originating the Brockhoeft Credit Facility, the Partnership paid the Lender an origination fee in the amount of $300,000.  On June 21, 2010, the Partnership entered into the First Amendment to Loan and Security Agreement (the “Amended Loan Agreement”), pursuant to which the maturity date on the Brockhoeft Credit Facility was extended from September 20, 2010 to June 21, 2012 and the Partnership’s existing and future assets were permitted to secure our guaranty of a $15.0 million loan (the “UDF I – Brockhoeft Loan”) from the Lender, as agent for a group of lenders, to UDF I.  In consideration for amending the Brockhoeft Credit Facility, the Partnership paid the Lender an amendment fee in the amount of $150,000, which was amortized over the life of the Amended Loan Agreement.  In connection with the guaranty, we received from UDF I a monthly fee equal to 3% per annum of the outstanding balance of the UDF I – Brockhoeft Loan.  The Amended Loan Agreement also provided for cross-default of the Brockhoeft Credit Facility with the UDF I – Brockhoeft Loan.  On June 21, 2012, the Partnership entered into the Second Amendment to Loan and Security Agreement (the “Second Amended Loan Agreement”), pursuant to which the maturity date on the Brockhoeft Credit Facility was extended from June 21, 2012 to June 21, 2014.  Our guaranty of the UDF I – Brockhoeft Loan was also modified effective June 21, 2012, such that UDF I agreed to pay us a monthly fee equal to 1/12th of 1% of the outstanding principal balance of the UDF I – Brockhoeft Loan.  In consideration for entering into the Second Amended Loan Agreement, the Partnership paid the Lender an additional amendment fee in the amount of $150,000, which is being amortized over the life of the Second Amended Loan Agreement. UDF I paid off the UDF I – Brockhoeft Loan in December 2012, thus extinguishing the Partnership’s guaranty of the UDF I – Brockhoeft Loan and extinguishing the cross-default of the Brockhoeft Credit Facility with the UDF I – Brockhoeft Loan.  We believe that the interest rate and terms of the Brockhoeft Credit Facility, the Amended Loan Agreement and the Second Amended Loan Agreement were consistent with those offered by financial institutions.
	The Partnership’s eligibility to borrow up to $15.0 million under the Brockhoeft Credit Facility is determined pursuant to a borrowing base.  The borrowing base is equal to (a) the lesser of (i) up to 50% of the aggregate principal amount outstanding under the Partnership’s eligible notes, (ii) up to 50% of the face amount of the Partnership’s eligible notes, or (iii) 40% of the appraised value of the real property subject to the liens securing the Partnership’s eligible notes; minus (b) any reserves required by the Lender.  Eligible notes are those promissory notes which are secured by first liens, meet certain other criteria established by the Lender, and are otherwise approved by the Lender for inclusion in the borrowing base.  The Second Amended Loan Agreement requires the Partnership to make various representations to the Lender and to comply with various covenants and agreements, including, without limitation, maintaining at least $30.0 million in eligible notes, maintaining an adjusted tangible net worth of no less than $250 million, maintaining its current line of business, operating its business in accordance with applicable laws, providing the Lender with information, financial statements and reports, and not permitting a change of control to occur.
	Effective as of June 21, 2012, the Partnership may not borrow any additional advances under the Second Amended Loan Agreement. The Partnership is required to repay the principal amount of the loan in equal installments of $1,250,000 on the 21st day of each March, June, September and December beginning on September 21, 2012.  The Partnership obtained a waiver from the Lender of the December 2012 principal payment and resumed making the quarterly principal payments in accordance with the terms of the Second Amended Loan Agreement in March 2013.  On June 21, 2014, the Partnership is required to pay the aggregate unpaid principal amount of all advances outstanding, all accrued but unpaid interest thereon, all fees and expenses owing to the lender and all other non-contingent obligations.
	If a default occurs under the Brockhoeft Credit Facility, the Lender may declare the Brockhoeft Credit Facility to be due and payable immediately.  A default may occur under the Brockhoeft Credit Facility in various circumstances including, without limitation, if (i) the Partnership fails to pay amounts due to the Lender when due under the Second Amended Loan Agreement, (ii) the Partnership fails to comply with its covenants and agreements with the Lender, (iii) the Partnership defaults under obligations for money borrowed in excess of $500,000, (iv) the Lender deems itself insecure or determines that a material adverse effect with respect to the Brockhoeft Credit Facility, the Partnership, or the Brockhoeft Credit Facility collateral has occurred, (v) a criminal action is filed against the Partnership under a federal or state racketeering statute, (vi) a bankruptcy action is filed with respect to the Partnership, (vii) the Partnership conceals, removes, or permits to be concealed or removed, any of its assets with the intent to hinder, delay or defraud the Lender or its other creditors, or (viii) the Second Amended Loan Agreement or other loan documents are terminated, become void or unenforceable, or any security interest issued in connection with the Brockhoeft Credit Facility ceases to be a valid and perfected first priority security interest in any portion of the Brockhoeft Credit Facility collateral.  In such event, the Lender may exercise any rights or remedies it may have, including, without limitation, increasing the interest rate to 12% per annum, prohibiting distributions to be made to the Partnership’s partners, and foreclosure of the Partnership’s assets.  Any such event may materially impair the Partnership’s ability to conduct its business.
	The Partnership intends to utilize the Brockhoeft Credit Facility as transitory indebtedness to provide liquidity and to reduce and avoid the need for large idle cash reserves, including usage to fund identified investments pending receipt of proceeds from the partial or full repayment of loans.  This allows the Partnership to keep funds invested in loans, instead of holding such loan repayment proceeds idle until new investments are identified.  The Partnership intends to use the Brockhoeft Credit Facility as a Partnership portfolio administration tool and not to provide long-term or permanent leverage on Partnership investments.  Proceeds from the operations of the Partnership will be used to repay the Brockhoeft Credit Facility.  As of September 30, 2013 and December 31, 2012, approximately $10.0 million and $13.8 million in principal was outstanding under the Brockhoeft Credit Facility, respectively.  Interest expense associated with the Brockhoeft Credit Facility was approximately $282,000 and $374,000, respectively, for the three months ended September 30, 2013 and 2012, and approximately $929,000 and $1.1 million, respectively, for the nine months ended September 30, 2013 and 2012.

Unit Redemption Program and Net Capital Proceeds Distribution Program [Text Block]	'
	H. Unit Redemption Program and Net Capital Proceeds Distribution Program
	Limited partners who have held their units for at least one year may request that the Partnership repurchase their units.  A limited partner wishing to have units repurchased must mail or deliver in writing a request to the Partnership indicating such desire. However, effective June 30, 2009, in order to conserve cash and in response to increasing requests for redemptions, we limited our redemptions primarily to those requested as a result of death, disability and exigent circumstances, to the extent our general partner determines there are sufficient funds to redeem units.  As stated below, our general partner will determine from time to time whether the Partnership has sufficient excess cash from operations to repurchase units, and there is no guarantee that the Partnership will repurchase any additional units in the future.  No units were redeemed from May 2010 through March 2012.  In April and July 2012, our general partner determined that the Partnership had sufficient excess cash from operations to repurchase some units as a result of the deaths of limited partners.  No units were redeemed from August 2012 through April 2013. In May 2013, our general partner determined that the Partnership had sufficient excess cash from operations to repurchase all outstanding units under repurchase requests resulting from the deaths of limited partners received by the Partnership through the end of April 2013. In addition, the Partnership began repurchasing units for redemption requests resulting from involuntary exigent circumstances effective May 16, 2013, as described below.
	As a result of the requirement to determine an estimated value of our units, the method for determining the purchase price for current and future redeemed units was revised as of October 15, 2010.  Except as described below for redemptions upon the death of a limited partner and for redemptions because of involuntary exigent circumstances after May 16, 2013, the purchase price for the redeemed units, for the period beginning after a limited partner has held the units for a period of one year, was (i) 92% of the Estimated Unit Value (as defined below) for any units held less than two years, (ii) 94% of the Estimated Unit Value for any units held for at least two years but less than three years, (iii) 96% of the Estimated Unit Value for any units held at least three years but less than four years, (iv) 98% of the Estimated Unit Value for any units held at least four years but less than five years; and (v) 100% of the Estimated Unit Value for any units held at least five years. The price the Partnership paid for redeemed units was offset by any net proceeds from capital transactions previously distributed to the redeeming limited partner in respect of such units as a return of his or her capital contributions.  In addition, the purchase price for units redeemed upon the death of a limited partner was 100% of the Estimated Unit Value, with the aggregate annual number of units redeemed upon death of a limited partner not to exceed 1% of units outstanding in the preceding 12-month period. The price the Partnership paid for units redeemed upon the death of a limited partner was offset by any net proceeds from capital transactions previously distributed to the deceased limited partner, or his or her estate, in respect of such units as a return of capital contributions.  For purposes of establishing the redemption price per unit, “Estimated Unit Value” shall mean the most recently disclosed reasonable estimated value of the Partnership’s units of limited partnership interest as determined by our general partner.  On September 6, 2013, our general partner determined the most recent Estimated Unit Value to be $20.00 per unit, which will be used as the Estimated Unit Value until such time as our general partner provides a new estimated value of the Partnership’s units of limited partnership interest.
	Effective May 16, 2013, the Partnership announced the following changes to the unit redemption program:
	·            To the extent that the Partnership’s general partner determines that there are sufficient funds to redeem units, the Partnership will only redeem units upon the death, or other involuntary exigent circumstances, of a limited partner, subject to certain restrictions and limitations, and
	·            A limited partner or their estate, heir or beneficiary must present all of its units then-owned for redemption – no partial redemptions of a limited partner’s holdings will be permitted
	The purchase price for the units redeemed because of involuntary exigent circumstances, for the period beginning after a limited partner has held the units for a period of one year, will be (1) 92% of the purchase price actually paid for any units held less than two years, (2) 94% of the purchase price actually paid for any units held for at least two years but less than three years, (3) 96% of the purchase price actually paid for any units held at least three years but less than four years, (4) 98% of the purchase price actually paid for any units held at least four years but less than five years and (5) the lesser of the purchase price actually paid for any units held at least five years or the Estimated Unit Value. The purchase price for units redeemed upon the death of a limited partner will be the lesser of (1) the price the limited partner actually paid for the units or (2) the Estimated Unit Value. The purchase price for any redeemed units will be offset by any net proceeds from capital transactions previously distributed to the limited partner, or his or her estate, in respect of such units as a return of capital contributions.  Once a limited partner’s outstanding units have been redeemed, the investor is no longer considered a limited partner.
	The Partnership will not redeem in excess of 5% of the weighted average number of units outstanding during the 12-month period immediately prior to the date of redemption.  Our general partner reserves the right in its sole discretion at any time and from time to time to (1) waive the one-year holding period in the event of the death or bankruptcy of a limited partner or other exigent circumstances, (2) reject any request for redemption, (3) change the purchase price for redemptions, or (4) terminate, suspend and/or reestablish our unit redemption program.  Our general partner will determine from time to time whether the Partnership has sufficient excess cash from operations to repurchase units.  Generally, the cash available for redemption will be limited to 1% of the operating cash flow from the previous fiscal year, plus any net proceeds from the DRIP and Secondary DRIP.  If the funds set aside for the unit redemption program are not sufficient to accommodate all requests, at such time, if any, when sufficient funds become available, pending requests will be honored among all requesting limited partners as follows: first, pro rata as to redemptions upon the death or disability of a limited partner; next, pro rata as to limited partners who demonstrate, in the discretion of our general partner, another involuntary exigent circumstance, such as bankruptcy; and, finally, pro rata as to all other redemption requests, if any, until all other requests for redemption have been met.
	As stated above, effective May 16, 2013, the unit redemption program is limited only to the death or other involuntary exigent circumstances of a limited partner.  Therefore, limited partners wishing to redeem their units after such date may do so only pursuant to Sections 9.6 and 11.3(f) of the Partnership Agreement.  Under such sections of the Partnership Agreement, any limited partner (an “Electing Partner”) may provide written notice to the Partnership of its election to receive its share of any net capital proceeds (the “Net Capital Proceeds Distribution Program”) received by the Partnership after May 15, 2013 that the Partnership decides to reinvest in additional loans.  If the Partnership ultimately decides to not reinvest net capital proceeds received by the Partnership in additional loans, such net capital proceeds shall not be eligible to be paid to Electing Partners pursuant to the Net Capital Proceeds Distribution Program, but shall be distributed in accordance with the other distribution provisions of the Partnership Agreement.  The election to participate in the Net Capital Proceeds Distribution Program will automatically and immediately cause the withdrawal of all of the Electing Partner’s pending requests for redemption pursuant to the Partnership’s unit redemption program, and the Electing Partner shall not be eligible to make any further requests for redemption pursuant to the unit redemption program. No redemptions have been made under the Net Capital Proceeds Distribution Program as of September 30, 2013.
	The Partnership complies with FASB ASC 480-10, Distinguishing Liabilities from Equity, which requires, among other things, that financial instruments that represent a mandatory obligation of the Partnership to repurchase limited partnership units be classified as liabilities and reported at settlement value.  We believe that limited partnership units tendered for redemption by the unit holder under the Partnership’s unit redemption program do not represent a mandatory obligation until such redemptions are approved at the discretion of our general partner, and that limited partnership units tendered for redemption by the unit holder under the Net Capital Proceeds Distribution Program do not represent a mandatory obligation until our general partner determines, in its sole discretion, to reinvest net capital proceeds received by the Partnership after May 15, 2013 in additional loans.  At such time, we will reclassify such obligations from equity to an accrued liability based upon their respective settlement values.  As of September 30, 2013, we did not have any approved redemption requests included in our liabilities.

	I. Commitments and Contingencies
	From time to time, the Partnership enters into guarantees of debtors’ or affiliates’ borrowings and provides credit enhancements for the benefit of senior lenders in connection with the Partnership’s debtors and affiliates and investments in partnerships (collectively referred to as “guarantees”), and accounts for such guarantees in accordance with FASB ASC 460-10, Guarantees. Guarantees generally have fixed expiration dates or other termination clauses and may require payment of a fee by the debtor. A guarantee involves, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets.  The Partnership’s exposure to credit loss in the event of non-performance by the other party to the instrument is represented by the contractual notional amount of the guarantee.  In connection with related party guarantees, as required by the Partnership Agreement and the NASAA Mortgage Program Guidelines, the Partnership obtained an opinion from Jackson Claborn, Inc., an independent advisor, stating that these guarantees are fair and at least as reasonable to the Partnership as a guarantee to an unaffiliated borrower in similar circumstances.
	In February 2009, the Partnership deposited $1.5 million into a money market account (the “Deposit Account”) with LegacyTexas Bank (“LegacyTexas”) for the purpose of providing collateral to LegacyTexas for the benefit of UMTH Lending Company, L.P., a Delaware limited partnership (“UMTH Lending”).  UMTH Lending and the Partnership’s general partner are each owned 99.9% by UMT Holdings and 0.1% by UMT Services, which serves as the general partner for both UMTH Lending and the Partnership’s general partner.  The Partnership provided LegacyTexas a security interest in the Deposit Account as further collateral for a loan (the “UMTH Lending Loan”) obtained by UMTH Lending from LegacyTexas.  In November 2010, UMTH Lending refinanced the UMTH Lending Loan with United Texas Bank (“UTB”).  In conjunction with this refinance, the Partnership deposited $1.5 million into a deposit account (the “UTB Deposit Account”) with UTB for the purpose of providing collateral to UTB for the benefit of UMTH Lending.  The UTB Deposit Account replaced the Deposit Account previously established with LegacyTexas.  The Partnership provided the UTB Deposit Account as further collateral for a loan obtained by UMTH Lending from UTB (the “UTB-UMTH Lending Loan”). Effective November 4, 2013, UMTH Lending refinanced the UTB-UMTH Lending Loan with City Bank. In conjunction with this refinance, the Partnership deposited approximately $1.4 million into a deposit account (the “City Bank Deposit Account”) with City Bank for the purpose of providing collateral to City Bank for the benefit of REO Property Company, L.P., a Texas limited partnership (“REO PC”). UMT Services serves as the general partner for both REO PC and the Partnership’s general partner.  The City Bank Deposit Account replaced the UTB Deposit Account.  See Note M, “Subsequent Events” for further discussion.  In consideration for providing the Deposit Account and UTB Deposit Account (collectively, the “UMTH Lending Deposit Accounts”) as collateral for the UMTH Lending Loan and the UTB-UMTH Lending Loan (collectively, the “UMTH Lending Loans”), UMTH Lending agreed to pay the Partnership a fee equal to 3% per annum of the amount outstanding in the UMTH Lending Deposit Accounts, paid in 12 monthly installments for each year that the UMTH Lending Deposit Accounts secure the UMTH Lending Loans (the “Lending Credit Enhancement”).  The UTB Deposit Account is included as restricted cash on the Partnership’s balance sheet.  This fee is included in mortgage and transaction service revenues – related parties income (see Note K for further discussion).
	In August 2009, the Partnership entered into a guaranty (the “UMT HF TCB Guaranty”) with Texas Capital Bank, National Association (“Texas Capital”), by which the Partnership guaranteed the repayment of up to $5.0 million owed to Texas Capital with respect to that certain promissory note between UMT Home Finance, L.P., a Delaware limited partnership (“UMT Home Finance”), and Texas Capital.  UMT Home Finance is a wholly-owned subsidiary of UMT.  An affiliate of the Partnership’s general partner serves as the advisor to UMT.  In connection with the UMT HF TCB Guaranty, the Partnership entered into a letter agreement with UMT Home Finance which provided for UMT Home Finance to pay the Partnership annually, in advance, an amount equal to 1% of the Partnership’s maximum exposure under the UMT HF TCB Guaranty (i.e., $50,000 per annum) through August 2012.  Effective August 28, 2012, the letter agreement was modified and UMT Home Finance agreed to pay the Partnership a monthly fee equal to 1/12th of 1% of the outstanding principal balance of the Texas Capital loan.  These fees are included in mortgage and transaction service revenues – related parties income (see Note K for further discussion).
	In April 2010, the Partnership entered into a guaranty (the “UDF IV HF Guaranty”) for the benefit of Community Trust Bank of Texas (“CTB”), pursuant to which the Partnership guaranteed the repayment of up to $6.0 million owed to CTB with respect to a revolving line-of-credit loan between UDF IV Home Finance, L.P., a Delaware limited partnership (“UDF IV Home Finance”), and CTB.  Effective July 31, 2013, UDF IV Home Finance entered into the First Amended and Restated Loan Agreement with CTB, pursuant to which CTB increased its commitment under the revolving line-of-credit loan from $6.0 million to $10.0 million.  UDF IV Home Finance is a wholly owned subsidiary of UDF IV.  The Partnership’s general partner serves as the asset manager for UDF IV, and an affiliate of the Partnership’s general partner serves as the advisor for UDF IV.  In connection with the UDF IV HF Guaranty, the Partnership entered into a letter agreement with UDF IV Home Finance which provided for UDF IV Home Finance to pay the Partnership an annual credit enhancement fee equal to 1% of the maximum loan amount (i.e., $60,000 per annum) through July 2013.  Effective July 31, 2013, the letter agreement was modified and UDF IV Home Finance agreed to pay the Partnership a monthly fee equal to 1/12th of 1% of the outstanding principal balance of the CTB loan.  These fees are included in mortgage and transaction service revenues – related parties income (see Note K for further discussion).
	In April 2010, the Partnership entered into a guaranty (the “UMT 15th Street Guaranty”) for the benefit of CTB, pursuant to which the Partnership guaranteed the repayment of up to $1.6 million owed to CTB with respect to a loan between UMT 15th Street, L.P., a Delaware limited partnership (“UMT 15th Street”), and CTB.  UMT 15th Street is a wholly owned subsidiary of UMT.  An affiliate of the Partnership’s general partner serves as the advisor to UMT.  In connection with the UMT 15th Street Guaranty, the Partnership entered into a letter agreement with UMT 15th Street which provides for UMT 15th Street to pay the Partnership a monthly credit enhancement fee equal to 1/12th of 1% of the outstanding principal balance on the loan at the end of the month.  This fee is included in mortgage and transaction service revenues – related parties income (see Note K for further discussion).
	In June 2010, UDF I obtained the $15.0 million UDF I – Brockhoeft Loan from the Lender, as agent for a group of lenders. As security for the UDF I – Brockhoeft Loan, the Partnership provided the Lender with a guaranty of repayment on the UDF I – Brockhoeft Loan (the “UDF I Brockhoeft Guaranty”), which is secured by a lien on all of the Partnership’s existing and future assets.  The Partnership’s general partner serves as the asset manager for UDF I.  In consideration of the Partnership’s secured guaranty, commencing July 31, 2010, UDF I agreed to pay the Partnership a monthly fee equal to 3% per annum of the outstanding balance of the UDF I – Brockhoeft Loan.  Effective June 21, 2012, the agreement was modified and UDF I agreed to pay the Partnership a monthly fee equal to 1/12th of 1% of the outstanding principal balance of the UDF I – Brockhoeft Loan.  UDF I paid off the UDF I – Brockhoeft Loan in December 2012, thus extinguishing the guaranty.  These fees are included in mortgage and transaction service revenues – related parties income (see Note K for further discussion).
	In August 2010, the Partnership entered into a guaranty (the “UDF IV Acquisitions Guaranty”) for the benefit of CTB, pursuant to which the Partnership guaranteed the repayment of $8.0 million (subsequently increased to $15.0 million) owed to CTB with respect to a revolving line-of-credit loan between UDF IV Acquisitions, L.P., a Delaware limited partnership (“UDF IV Acquisitions”), and CTB.  UDF IV Acquisitions is a wholly owned subsidiary of UDF IV.  The Partnership’s general partner serves as the asset manager for UDF IV, and an affiliate of the Partnership’s general partner serves as the advisor for UDF IV.  In connection with the UDF IV Acquisitions Guaranty, the Partnership entered into a letter agreement with UDF IV Acquisitions which provides for UDF IV Acquisitions to pay the Partnership a monthly credit enhancement fee equal to 1/12th of 1% of the outstanding principal balance on the revolving line-of-credit at the end of the month.  This fee is included in mortgage and transaction service revenues – related parties income (see Note K for further discussion).
	In December 2010, the Partnership entered into a guaranty (the “UDF IV Finance II Guaranty”) for the benefit of The F&M Bank and Trust Company (“F&M”), pursuant to which the Partnership guaranteed the repayment of up to $5.0 million (subsequently increased to $10.0 million) owed to F&M with respect to a loan between UDF IV Finance II, L.P., a Delaware limited partnership (“UDF IV Finance II”), and F&M.  Effective October 31, 2013, UDF IV Finance II entered into the Second Amendment to Amended and Restated Loan Agreement with F&M, pursuant to which F&M increased its commitment under the revolving line-of-credit loan from $10.0 million to $15.0 million.  See Note M, “Subsequent Events” for further discussion.

	Land Development and certain of its affiliates receive fees in connection with the acquisition and management of the assets and reimbursement of costs of the Partnership.
	We reimburse UMTH General Services, L.P. (“General Services”), a Delaware limited partnership, for operating expenses incurred by General Services in assisting Land Development in our management (the “Operating Expense Reimbursement”).  General Services and Land Development are each owned 99.9% by UMT Holdings and 0.1% by UMT Services, which serves as the general partner for both General Services and Land Development.
	We incurred Placement Fees of 3% of the net amount available for investment in mortgages for fees and expenses associated with the selection and origination of mortgages, including, but not limited to, legal fees and expenses, travel and communications expenses, costs of appraisals, accounting fees and expenses, and title insurance funded by us.  Such fees are amortized into expense on a straight line basis and are currently being paid to Land Development.  The unpaid portion of these fees is included in accrued liabilities – related parties on our balance sheet.
	Land Development currently receives an unsubordinated promotional interest equal to 10% of cash available for distribution prior to the return to our limited partners of all of their capital contributions and an 8% annual cumulative (non-compounded) return on their net capital contributions.  After our limited partners receive a return of their net capital contributions and an 8% annual cumulative (non-compounded) return on their net capital contributions, Land Development will receive a subordinated promotional interest equal to 15% of remaining cash available for distribution, including net proceeds from capital transactions or a pro rata portion thereof.
	Land Development receives a carried interest, which is an equity interest in us to participate in all distributions, other than distributions attributable to its promotional interest of cash available for distribution and net proceeds from capital transactions. If Land Development enters into commitments to investments in mortgages in excess of 82% of the gross offering proceeds, it will be entitled to a carried interest equal to (a) 1% for the first 2.5% of commitments to investments in mortgages above 82% of the gross offering proceeds (or if commitments to investments in mortgages are above 82% but no more than 84.5%, 1% multiplied by the fractional amount of commitments to investments in mortgages above 82%), (b) 1% for the next 2% of additional commitments to investments in mortgages above 84.5% of the gross offering proceeds (or if commitments to investments in mortgages are above 84.5% but no more than 86.5%, 1% multiplied by the fractional amount of commitments to investments in mortgages above 84.5%) and (c) 1% for each additional 1% of additional commitments to investments in mortgages above 86.5% of the gross offering proceeds (or a fractional percentage equal to the fractional amount of any 1% of additional commitments to investments in mortgages).
	For services rendered in connection with the servicing of our loans, we incur a monthly Mortgage Servicing Fee payable to Land Development equal to one-twelfth of 0.25% of our aggregate outstanding development mortgage notes receivable balance as of the last day of the month.  Such fees are included in general and administrative – related parties expenses.  The unpaid portion of such fees is included in accrued liabilities – related parties on our balance sheet.
	An affiliate of Land Development serves as the advisor to UMT and UDF IV. The general partner of UDF LOF is a wholly-owned subsidiary of Land Development.  Land Development serves as the asset manager of UDF I, UDF IV and UDF LOF.
	The chart below summarizes the payment of related party fees and reimbursements associated with the Offering and origination and management of assets for the nine months ended September 30, 2013 and 2012.  We believe that these fees and reimbursements are reasonable and customary for comparable mortgage programs.

	Mortgage Notes Receivable – Related Parties
	In connection with mortgage notes receivable – related parties, participation interest – related party, and loan participations sold to related parties, as required by our Partnership Agreement and the NASAA Mortgage Program Guidelines, the Partnership obtained an opinion from Jackson Claborn, Inc., an independent advisor, stating that the transactions are fair and at least as reasonable to the Partnership as a transaction with an unaffiliated party in similar circumstances.
	UDF PM Note
	In September 2007, we originated a secured promissory note to UDF PM, LLC, a Texas limited liability company and wholly-owned subsidiary of UDF I (“UDF PM”), in the principal amount of approximately $6.4 million (the “UDF PM Note”).  Our general partner serves as the asset manager for UDF I.  The UDF PM Note, which bears an interest rate of 15% per annum, is initially collateralized by a second lien deed of trust on approximately 335 finished lots and 15 acres of land located in Texas and, per the Third Amendment to Secured Promissory Note, matures on September 4, 2014. In determining whether to modify the UDF PM Note, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  In connection with the UDF PM Note, UDF PM agreed to pay us commitment fees equal to 3% of each advance on the note, or $187,500.  We did not recognize any commitment fee income in connection with the UDF PM Note for the three or nine months ended September 30, 2013 or 2012.  For the three months ended September 30, 2013 and 2012, we recognized approximately $9,000 and $27,000, respectively, of interest income – related parties related to the UDF PM Note.  For the nine months ended September 30, 2013 and 2012, we recognized approximately $28,000 and $290,000, respectively, of interest income – related parties related to the UDF PM Note.  Approximately $270,000 and $280,000 is included in mortgage notes receivable – related parties as of September 30, 2013 and December 31, 2012, respectively.  Approximately $5,000 is included in accrued interest receivable – related parties as of December 31, 2012. There was no balance in accrued interest receivable – related parties associated with this loan as of September 30, 2013.
	UDF X Note
	In November 2007, we originated a secured promissory note to United Development Funding X, L.P., a Delaware limited partnership and wholly-owned subsidiary of our general partner (“UDF X”), in the principal amount of approximately $70.0 million (the “UDF X Note”).  In August 2008, we amended the UDF X Note to reduce the commitment amount to $25.0 million.  In November 2012, we amended the UDF X Note to increase the commitment amount to $26.0 million.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  The UDF X Note, which bears an interest rate of 15% per annum, is collateralized by a pledge of 100% of the ownership interests in UDF X and is payable on November 11, 2014, as amended.  In connection with the UDF X Note, UDF X agreed to pay us commitment fees equal to 3% of each advance on the note, or approximately $751,000.  For the three and nine months ended September 30, 2012, approximately $41,000 and $124,000 in commitment fee income is included in mortgage and transaction service revenues – related parties, respectively.  We did not recognize any commitment fee income in connection with the UDF X Note for the three or nine months ended September 30, 2013.  For the three months ended September 30, 2013 and 2012, we recognized approximately $806,000 and $884,000, respectively, of interest income – related parties related to the UDF X Note.  For the nine months ended September 30, 2013 and 2012, we recognized approximately $2.4 million and $2.6 million, respectively, of interest income – related parties related to the UDF X Note.  Approximately $20.1 million and $21.7 million is included in mortgage notes receivable – related parties as of September 30, 2013 and December 31, 2012, respectively.  Approximately $33,000 and $27,000 is included in accrued interest receivable – related parties as of September 30, 2013 and December 31, 2012, respectively.
	UDF NP Loan
	In December 2007, we originated a secured promissory note to UDF Northpointe, LLC, a Texas limited liability company which was a wholly-owned subsidiary of UDF I at the time of the note’s origination (“Northpointe LLC”), in the principal amount of approximately $6.0 million (the “UDF NP Loan”).  Our general partner serves as the asset manager for UDF I.  In December 2008, Northpointe LLC was purchased by an unrelated third party, which assumed the UDF NP Loan.  In May 2009, Northpointe LLC assigned its obligations associated with the UDF NP Loan and its interests in the collateral by a special warranty deed to UDF Northpointe II, L.P. (“Northpointe II”), a subsidiary of UDF I.  Concurrent with this assignment, Northpointe LLC entered into a contract for deed with Northpointe II whereby Northpointe LLC agreed to make payments to Northpointe II for all debt service payments in consideration for Northpointe II transferring ownership and possession of the collateral back to Northpointe LLC.  The secured promissory note, which bears an interest rate of 12% per annum, is initially collateralized by a second lien deed of trust on 251 finished lots and 110 acres of land in Texas and was payable on December 28, 2010.  The maturity date was extended to December 28, 2013 pursuant to a modification agreement effective as of June 30, 2011 which also increased the UDF NP Loan to a maximum of $15.0 million, pursuant to a second secured promissory note in the principal amount of $9.0 million.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  The second secured promissory note bears the same interest rate and is secured by the same collateral as the original promissory note.  For the three months ended September 30, 2013 and 2012, we recognized approximately $344,000 and $383,000, respectively, of interest income – related parties related to this loan.  For each of the nine months ended September 30, 2013 and 2012, we recognized approximately $1.1 million of interest income – related parties related to this loan.  Approximately $11.6 million and $13.4 million is included in mortgage notes receivable – related parties associated with the UDF NP Loan as of September 30, 2013 and December 31, 2012, respectively.  There was no balance in accrued interest receivable – related parties associated with this loan as of September 30, 2013 and December 31, 2012.
	UDF LOF Note
	In August 2008, we originated a secured revolving line-of-credit to UDF LOF in the principal amount of up to $25.0 million, pursuant to a Secured Line of Credit Promissory Note (the “UDF LOF Note”).  The general partner of UDF LOF is a wholly-owned subsidiary of our general partner, and our general partner serves as the asset manager for UDF LOF.  The UDF LOF Note, which bears interest at a base rate equal to 15% per annum, is secured by a lien of all of UDF LOF’s existing and future acquired assets.  In August 2011, we amended the UDF LOF Note to reduce the commitment amount to $10.0 million and extend the maturity date from August 20, 2011 to August 20, 2013. In August 2013, the note was amended to further extend the maturity date to August 20, 2014.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  In January 2010, the balance of the UDF LOF Note was paid in full, although UDF LOF still has the ability to draw on the UDF LOF Note until it matures.  In connection with this note, UDF LOF agreed to pay us commitment fees equal to 3% of each advance on the note, or approximately $587,000.  We did not recognize any commitment fee income or interest income – related parties related to the UDF LOF Note for the three or nine months ended September 30, 2013 or 2012.  There was no balance in mortgage notes receivable – related parties or accrued interest receivable – related parties associated with the UDF LOF Note as of September 30, 2013 or December 31, 2012.
	BTC Note
	In August 2008, we originated a secured promissory note with Buffington Texas Classic Homes, Ltd., a Texas limited partnership (“Buffington Classic”), in the principal amount of $2.0 million (the “BTC Note”).  Our general partner had a minority partner interest in Buffington Classic.  The secured note, which bears interest at 14% per annum, is secured by a first lien on finished lot inventory that is owned and controlled by Buffington Classic.  Pursuant to an Agreement and Plan of Merger dated November 30, 2009, Buffington Capital Homes, Ltd., a Texas limited partnership (“Buffington Capital”), merged into Buffington Texas Classic Homes, LLC (“BTC LLC”), which is ultimately owned and controlled by BHG.  Our general partner has a minority limited partnership interest in BHG.  As a result of the merger and pursuant to the Agreement and First Amendment to Loan Agreement dated December 8, 2009, BTC LLC succeeded to all the rights, responsibilities and obligations of Buffington Classic under the BTC Note.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  BTC LLC’s payment and performance of the BTC Note is guaranteed by Buffington Land, Ltd., a Texas limited partnership, and, pursuant to the Extension Agreement and Fifth Amendment to Loan Agreement dated August 21, 2013, is payable on August 21, 2014.  We did not recognize any interest income – related parties related to the BTC Note for the three or nine months ended September 30, 2013 or 2012.  There was no balance in mortgage notes receivable – related parties or accrued interest receivable – related parties associated with the BTC Note as of September 30, 2013 or December 31, 2012.
	HTC Loan
	Effective December 2008, we modified a secured promissory note evidencing a loan (the “HTC Loan”) in the principal amount of approximately $8.1 million to UDF I that we originated in December 2006 in the principal amount of approximately $6.9 million.  Our general partner serves as the asset manager for UDF I.  UDF I’s obligations under the HTC Loan are secured by a first lien deed of trust filed on 190 entitled single-family home lots located in Thornton, Colorado.  The HTC Loan bears interest at a base rate equal to 12% per annum and interest payments are due monthly.  Effective June 30, 2011, the HTC Loan was increased to a maximum of $12.8 million, pursuant to a second secured promissory note in the principal amount of $4.7 million.  The second secured promissory note bears the same interest rate and is secured by the same collateral as the original promissory note.  The HTC Loan had an initial maturity date of December 31, 2011, but was extended to June 30, 2012 pursuant to a fourth amendment to secured promissory note effective as of June 30, 2011. Effective June 30, 2012, the principal amount available under the HTC Loan was increased to a maximum of $15.6 million and the maturity date was extended to June 30, 2015, pursuant to a fifth amendment to secured promissory note.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  For the three months ended September 30, 2013 and 2012, we recognized approximately $378,000 and $367,000, respectively, of interest income – related parties related to the HTC Loan.  For the nine months ended September 30, 2013 and 2012, we recognized approximately $1.2 million and $1.1 million, respectively, of interest income – related parties related to the HTC Loan.  Approximately $12.2 million and $12.9 million is included in mortgage notes receivable – related parties as of September 30, 2013 and December 31, 2012, respectively, related to the HTC Loan.  There was no balance in accrued interest receivable – related parties associated with the HTC Loan as of September 30, 2013 or December 31, 2012.
	Ash Creek Note
	In April 2011, we originated a promissory note to UDF Ash Creek, L.P. (the “Ash Creek Note”), a Delaware limited partnership and wholly-owned subsidiary of UDF I, in the principal amount of $50,000.  Our general partner serves as the asset manager for UDF I.  The Ash Creek Note, which bears interest at a base rate equal to 15% per annum, was originally payable on December 5, 2011.  Effective December 5, 2011, we entered into an extension agreement with the borrower, pursuant to which the maturity date of the Ash Creek Note was extended to December 21, 2012.  In December 2012, we amended the Ash Creek Note to increase the commitment amount to $65,000 and extend the maturity date to December 21, 2013.  The Ash Creek Note is secured by a second lien deed of trust.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  For the three months ended September 30, 2013 and 2012, we recognized approximately $3,000 and $2,000, respectively, of interest income – related parties related to the Ash Creek Note.  For the nine months ended September 30, 2013 and 2012, we recognized approximately $7,000 and $6,000, respectively, of interest income – related parties related to the Ash Creek Note.  Approximately $67,000 and $58,000 is included in mortgage notes receivable – related parties as of September 30, 2013 and December 31, 2012, respectively, related to the Ash Creek Note.  Approximately $4,000 and $6,000 is included in accrued interest receivable – related parties associated with the Ash Creek Note as of September 30, 2013 and December 31, 2012, respectively.
	Participation Interest – Related Party
	In September 2008, we entered into an Economic Interest Participation Agreement with UMT pursuant to which we purchased (i) an economic interest in the UMT Loan and (ii) a purchase option to acquire a full ownership participation interest in the UMT Loan (the “Option”).  Our general partner serves as the asset manager for UDF I.  An affiliate of our general partner serves as the advisor to UMT.  As of December 31, 2010, the UMT Loan was a $60.0 million revolving line-of-credit facility evidenced by a Third Amended and Restated Secured Line of Credit Promissory Note dated as of August 17, 2009, as extended to December 31, 2010 by an amendment effective December 31, 2009.  Effective December 31, 2010, the UMT Loan was subsequently increased to $75.0 million and the maturity date was extended to December 31, 2011, as evidenced by a Second Amendment to Third Amended and Restated Secured Line of Credit Promissory Note dated as of December 31, 2010.  Effective December 31, 2011, the UMT Loan was amended and the maturity date was extended to December 31, 2012, as evidenced by a Third Amendment to Third Amended and Restated Secured Line of Credit Promissory Note dated as of December 31, 2011.  Effective December 31, 2012, the UMT Loan was subsequently increased to $82.0 million and the maturity date was extended to December 31, 2013 as evidenced by a Fourth Amendment and Joinder Agreement to Third Amended and Restated Secured Line of Credit Promissory Note dated as of December 31, 2012.   Effective October 1, 2013, the maturity date of the UMT Loan was further extended to December 31, 2014 and the interest rate was reduced to 9.25% as evidenced by a Fifth Amendment to Third Amended and Restated Secured Line of Credit Promissory Note with UMT (as amended, the “UMT Note”).  See Note M, “Subsequent Events” for further discussion.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  The UMT Loan is secured by a security interest in the assets of UDF I including UDF I’s land development loans and equity investments pursuant to the First Amended and Restated Security Agreement dated as of September 30, 2004, executed by UDF I in favor of UMT (the “Security Agreement”).
	Pursuant to the Economic Interest Participation Agreement, each time UDF I requests an advance of principal under the UMT Note, we will fund the required amount to UMT for application to its funding obligation to UDF I under the UMT Loan and our economic interest in the UMT Loan will increase proportionately.  Our economic interest in the UMT Loan gives us the right to receive payment from UMT of principal and accrued interest relating to amounts funded by us to UMT which are applied towards UMT’s funding obligations to UDF I under the UMT Loan.  We may abate our funding obligations under the Economic Interest Participation Agreement at any time for a period of up to twelve months by giving UMT notice of the abatement.
	The Option gives us the right to convert our economic interest into a full ownership participation interest in the UMT Loan at any time by giving written notice to UMT and paying an exercise price of $100.  The participation interest includes all rights incidental to ownership of the UMT Note and the Security Agreement, including participation in the management and control of the UMT Loan.  UMT will continue to manage and control the UMT Loan while we own an economic interest in the UMT Loan.  If we exercise our Option and acquire a participation interest in the UMT Loan, UMT will serve as the loan administrator but both UMT and we will participate in the control and management of the UMT Loan.  The purpose of the UMT Loan is to finance UDF I’s investments in real estate development projects.  The UMT Loan interest rate is the lower of 14% per annum or the highest rate allowed by law.  UDF I may use the UMT Loan proceeds to finance indebtedness associated with the acquisition of any assets and to seek income that qualifies under the Real Estate Investment Trust provisions of the Internal Revenue Code of 1986, as amended, to the extent such indebtedness, including indebtedness financed by funds advanced under the UMT Loan and indebtedness financed by funds advanced from any other source, including senior debt, is no less than 68% of the appraised value of all subordinate loans and equity interests for land development and/or land acquisition owned by UDF I and 75% for first lien secured loans for land development and/or acquisitions owned by UDF I.  For the three months ended September 30, 2013 and 2012, we recognized approximately $2.5 million and $2.3 million, respectively, of interest income – related parties related to this Economic Interest Participation Agreement.  For the nine months ended September 30, 2013 and 2012, we recognized approximately $7.7 million and $6.9 million, respectively, of interest income – related parties related to this Economic Interest Participation Agreement.  Approximately $2.6 million is included in accrued interest receivable – related parties associated with this Economic Interest Participation Agreement as of December 31, 2012. There was no balance in accrued interest receivable – related parties associated with this Economic Interest Participation Agreement as of September 30, 2013.
	The UMT Loan was subordinate to the UDF I – Brockhoeft Loan through December 2012.  The UMT Loan is subordinate to a UDF I senior credit facility for $10.0 million entered into on March 5, 2013.  As of September 30, 2013 and December 31, 2012, approximately $71.8 and $74.7 million related to the Economic Interest Participation Agreement is included in participation interest – related party, respectively.
Loan Participations Sold to Related Parties
From inception through September 30, 2013, we have entered into 10 loan participation agreements with related parties whereby a related party has purchased a participation interest in a mortgage investment that we have originated.  As of September 30, 2013, 6 of these agreements remain outstanding.
Our related parties participate in these mortgage investments by funding our lending obligations up to a maximum amount for each participation.  Such participations entitle our related parties to receive payments of principal up to the amounts they have funded and interest from our borrower on the amounts they have funded, and to share in the proceeds of the collateral for the loan, including the land and related improvements to residential property owned by the borrowers and/or the ownership interests of the borrower that secure the original mortgage investment.  The income earned by our related parties and the amounts our borrowers owe to our related parties for principal and interest earned with respect to these participation agreements are not reflected in our financial statements.
BTC Note
In August 2008, we originated the $2.0 million BTC Note with Buffington Classic.  Effective March 2010, we entered into a Participation Agreement (“BTC Participation Agreement”) with UDF IV, pursuant to which UDF IV purchased a participation interest in the BTC Note.  Our general partner serves as the asset manager of UDF IV.  Pursuant to the BTC Participation Agreement, UDF IV will participate in the BTC Note by funding our lending obligations under the BTC Note.  The BTC Participation Agreement gives UDF IV the right to receive repayment of all principal and accrued interest relating to amounts funded by them under the BTC Participation Agreement.  UDF IV’s participation interest is repaid as Buffington Classic repays the BTC Note.  For each loan originated, Buffington Classic is required to pay interest monthly and to repay the principal advanced no later than 12 months following the origination of the loan.  The BTC Note, as amended, matures in August 2014.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.
We are required to purchase back from UDF IV the participation interest in the BTC Note (i) upon a foreclosure of our assets by our lenders, (ii) upon the maturity of the BTC Note, or (iii) at any time upon 30 days prior written notice from UDF IV.  In such event, the purchase price paid to UDF IV will be equal to the outstanding principal amount of the BTC Note on the date of termination, together with all accrued interest due thereon, plus any other amounts due to UDF IV under the BTC Participation Agreement.
On April 9, 2010, we entered into an Agent – Participant Agreement with UDF IV (the “Agent Agreement”).  In accordance with the Agent Agreement, we will continue to manage and control the BTC Note and UDF IV has appointed us as its agent to act on its behalf with respect to all aspects of the BTC Note, provided that, pursuant to the Agent Agreement, UDF IV retains approval rights in connection with any material decisions pertaining to the administration and services of the loan and, with respect to any material modification to the loan and in the event that the loan becomes non-performing, UDF IV shall have effective control over the remedies relating to the enforcement of the loan, including ultimate control of the foreclosure process.
As of September 30, 2013 and December 31, 2012, we did not have an outstanding balance in mortgage notes receivable – related parties or accrued interest receivable – related parties associated with the BTC Note.  We did not recognize any interest income associated with the BTC Note for the three or nine months ended September 30, 2013 or 2012.  As of September 30, 2013 and December 31, 2012, UDF IV had a participation interest associated with the BTC Participation Agreement of approximately $355,000 and $499,000, respectively.  The UDF IV participation interest is not included on our balance sheet.
TR II Finished Lot Note
In August 2009, we originated a $3.4 million secured promissory note (the “TR II Finished Lot Note”) with CTMGT Travis Ranch II, LLC, an unaffiliated Texas limited liability company.  The TR II Finished Lot Note was originally secured by a subordinate, second lien deed of trust recorded against finished residential lots in the Travis Ranch residential subdivision located in Kaufman County, Texas.  The TR II Finished Lot Note is guaranteed by the limited liability company owners of the borrower and by the principal of the borrower.  The interest rate under the TR II Finished Lot Note is 15%.  The borrower obtained a senior loan secured by a first lien deed of trust on the finished lots, which was paid in full in the first quarter of 2013. As a result, our deed of trust became a first lien.  For so long as the senior loan was outstanding, proceeds from the sale of the residential lots securing the TR II Finished Lot Note were paid to the senior lender and were applied to reduce the outstanding balance of the senior loan.  Following the payment of the senior lien in full, the proceeds from the sale of the residential lots securing the TR II Finished Lot Note are required to be used to repay the TR II Finished Lot Note.  The TR II Finished Lot Note was due and payable in full on August 28, 2012.  Pursuant to a loan modification agreement effective August 28, 2012, the maturity date on the TR II Finished Lot Note was extended to January 28, 2013.  The TR II Finished Lot Note was increased to $3.8 million pursuant to a Borrower’s Certificate effective as of December 31, 2012.  Pursuant to a second loan modification agreement effective January 28, 2013, the maturity date on the TR II Finished Lot Note was extended to January 28, 2014.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.
Effective June 2010, we entered into a loan participation agreement with UDF IV pursuant to which UDF IV purchased a participation interest (the “TR II Finished Lot Participation”) in the TR II Finished Lot Note.  Our general partner serves as the asset manager of UDF IV.  Pursuant to the TR II Finished Lot Participation, UDF IV is entitled to receive repayment of its participation in the outstanding principal amount of the TR II Finished Lot Note, plus accrued interest thereon, over time as the borrower repays the loan.
As of September 30, 2013 and December 31, 2012, we did not have an outstanding balance in mortgage notes receivable or accrued interest receivable associated with the TR II Finished Lot Note.  We did not recognize any interest income associated with the TR II Finished Lot Note for the three or nine months ended September 30, 2013 or 2012.  As of September 30, 2013 and December 31, 2012, UDF IV had a participation interest associated with the TR II Finished Lot Participation of approximately $3.6 million.  The UDF IV participation interest is not included on our balance sheet.
TR Paper Lot Note
In September 2009, we originated an $8.1 million secured promissory note (the “TR Paper Lot Note”) with CTMGT Travis Ranch, LLC, an unaffiliated Texas limited liability company.  The borrower owns paper lots in the Travis Ranch residential subdivision of Kaufman County, Texas.  A “paper” lot is a residential lot shown on a plat that has been accepted by the city or county, but which is currently undeveloped or under development.  The TR Paper Lot Note was initially secured by a pledge of the equity interests in the borrower instead of a real property lien, effectively subordinating the TR Paper Lot Note to all real property liens.  The TR Paper Lot Note is guaranteed by the limited liability company owners of the borrower and by the principal of the borrower.  The interest rate under the TR Paper Lot Note is 15%. The borrower has obtained a senior loan secured by a first lien deed of trust on the paper lots.  For so long as the senior loan is outstanding, proceeds from the sale of the paper lots will be paid to the senior lender and will be applied to reduce the outstanding balance of the senior loan.  After the senior lien is paid in full, the proceeds from the sale of the paper lots are required to be used to repay the TR Paper Lot Note.  The TR Paper Lot Note was due and payable in full on September 24, 2012.  Pursuant to a loan modification agreement effective September 24, 2012, the maturity date on the TR Paper Lot Note was extended to January 28, 2013.  The TR Paper Lot Note was increased to $11.0 million pursuant to a Borrower’s Confirmation Certificate effective as of December 31, 2012.  Pursuant to a second loan modification agreement effective January 28, 2013, the maturity date on the TR Paper Lot Note was extended to January 28, 2014.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.
Effective June 2010, we entered into a loan participation agreement with UDF IV pursuant to which UDF IV purchased a participation interest (the “TR Paper Lot Participation”) in the TR Paper Lot Note.  Our general partner serves as the asset manager of UDF IV.  Pursuant to the TR Paper Lot Participation, UDF IV is entitled to receive repayment of its participation in the outstanding principal amount of the TR Paper Lot Note, plus its proportionate share of accrued interest thereon, over time as the borrower repays the TR Paper Lot Note.
As of September 30, 2013 and December 31, 2012, we did not have an outstanding balance in mortgage notes receivable or accrued interest receivable associated with the TR Paper Lot Note.  We did not recognize any interest income associated with the TR Paper Lot Note for the three or nine months ended September 30, 2013 or 2012.  As of September 30, 2013 and December 31, 2012, UDF IV had a participation interest associated with the TR Paper Lot Participation of approximately $12.9 million and $10.6 million, respectively.  The UDF IV participation interest is not included on our balance sheet.
Luckey Ranch Note
In November 2008, we purchased a $1.7 million secured promissory note (the “Luckey Ranch Note”) from San Antonio Holding Company, Ltd., an unaffiliated Texas limited partnership (“SAHC”).  SAHC originated the loan in October 2006 with Luckey Ranch Global Associates, an unaffiliated Texas general partnership (“Luckey Ranch”).  The Luckey Ranch Note was initially secured by a second lien on approximately 610 acres of land located in Bexar County, Texas.  The interest rate on the Luckey Ranch Note was 12% and the Luckey Ranch Note matured on September 30, 2012, in accordance with the Tenth Modification Agreement entered into in September 2011.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.
Effective May 2011, we entered into a loan participation agreement with UDF LOF pursuant to which UDF LOF purchased a participation interest (the “Luckey Ranch Participation”) in the Luckey Ranch Note.  The general partner of UDF LOF is a wholly-owned subsidiary of our general partner, and our general partner serves as the asset manager for UDF LOF.  Pursuant to the Luckey Ranch Participation, UDF LOF was entitled to receive repayment of its participation in the outstanding principal amount of the Luckey Ranch Note, plus its proportionate share of accrued interest thereon, over time as the borrower repaid the Luckey Ranch Note. The Luckey Ranch Note and Luckey Ranch Participation were subsequently paid in full in October 2012.
As of September 30, 2013 and December 31, 2012, we did not have an outstanding balance in mortgage notes receivable or accrued interest receivable associated with the Luckey Ranch Note.  We did not recognize any interest income associated with the Luckey Ranch Note for the three or nine months ended September 30, 2013.  For the three and nine months ended September 30, 2012, we recognized approximately $18,000 and $49,000, respectively, of interest income associated with the Luckey Ranch Note.  The UDF LOF participation interest is not included on our balance sheet.
Buffington Brushy Creek Note
In May 2008, we originated a $4.7 million secured promissory note (the “Buffington Brushy Creek Note”) with Buffington Brushy Creek, Ltd., an unaffiliated Texas limited liability company, and Buff Star Ventures, Ltd., an unaffiliated Texas limited liability company, as co-borrowers (collectively, “Buff Star”).  The Buffington Brushy Creek Note was secured by a pledge of ownership interests in Buff Star. Buff Star owns partnership interests in a limited partnership that owns finished lots and entitled land in a residential subdivision in Travis County, Texas.  The interest rate under the Buffington Brushy Creek Note was 16%.  Pursuant to the Second Amendment to Secured Promissory Note entered into in May 2011, the maturity date of the Buffington Brushy Creek Note was May 19, 2013.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.
Effective May 2011, we entered into a loan participation agreement with UDF LOF pursuant to which UDF LOF purchased a participation interest (the “Brushy Creek Participation”) in the Buffington Brushy Creek Note.  The general partner of UDF LOF is a wholly-owned subsidiary of our general partner and our general partner serves as the asset manager for UDF LOF.  Pursuant to the Brushy Creek Participation, UDF LOF was entitled to receive repayment of its participation in the outstanding principal amount of the Buffington Brushy Creek Note, plus its proportionate share of accrued interest thereon, over time as the borrower repaid the note.  The Buffington Brushy Creek Note and Brushy Creek Participation were paid in full in May 2012.
As of September 30, 2013 and December 31, 2012, we did not have an outstanding balance in mortgage notes receivable or accrued interest receivable associated with the Buffington Brushy Creek Note.  We did not recognize any interest income associated with the Buffington Brushy Creek Note for the three or nine months ended September 30, 2013 or 2012.  The UDF LOF participation interest is not included on our balance sheet.
CTMGT Note
In December 2007, we originated a $25.0 million secured promissory note (the “CTMGT Note”) with CTMGT, LLC, an unaffiliated Texas limited liability company and its subsidiaries, who are co-borrowers of the CTMGT Note.  The CTMGT Note was subsequently increased to $50.0 million pursuant to an amendment entered into in July 2008, and to $64.5 million pursuant to an amendment entered into in November 2011.  The CTMGT Note is a co-investment loan secured by multiple investments.  These investments are cross-collateralized and are secured by collateral-sharing arrangements in second liens covering finished lots and entitled land, pledges of the ownership interests in the borrowing entities, and guaranties.  The collateral-sharing arrangements with our affiliates and our borrowers allocate the proceeds of the co-investment collateral between us and our affiliates.  Under these collateral-sharing arrangements for the CTMGT Note, we are entitled to receive 75% of collateral proceeds.  In the event of a borrower’s bankruptcy, we are entitled to receive 100% of the collateral proceeds after payment of the senior lenders, ahead of payment to our affiliates.  The CTMGT collateral is located in multiple counties in the greater Dallas-Fort Worth area and surrounding counties.  The interest rate on the CTMGT Note is 16.25%.  Pursuant to the amendment entered into in November 2011, the maturity date of the CTMGT Note was July 1, 2012.  Pursuant to a second amendment entered into in July 2012, the maturity date of the CTMGT Note was extended to July 1, 2013.  Effective July 1, 2013, we entered into a Third Extension and Modification Agreement with CTMGT, LLC, pursuant to which the maturity date of the CTMGT Note was further extended to July 1, 2014.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.

UDF NP Note
In December 2007, we originated the $6.0 million UDF NP Loan with Northpointe LLC.  In December 2008, Northpointe LLC was purchased by an unrelated third party which assumed the UDF NP Loan.  In May 2009, Northpointe LLC assigned its obligations associated with the UDF NP Loan and its interests in the collateral by special warranty deed to Northpointe II, a subsidiary of UDF I.  Concurrent with this assignment, Northpointe LLC entered into a contract for deed with Northpointe II whereby Northpointe LLC agreed to make payments to Northpointe II for all debt service payments in consideration for Northpointe II transferring ownership and possession of the collateral back to Northpointe LLC.  The secured promissory note, which bears an interest rate of 12% per annum, is initially collateralized by a second lien deed of trust on 251 finished lots and 110 acres of land in Texas and was payable on December 28, 2010.  The maturity date was extended to December 28, 2013 pursuant to a modification agreement effective as of June 30, 2011, which also increased the UDF NP Loan to a maximum of $15.0 million, pursuant to a second secured promissory note in the principal amount of $9.0 million.  In determining whether to modify this loan, we evaluated the economic conditions, the estimated value and performance of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors.  The second secured promissory note bears the same interest rate and is secured by the same collateral as the original promissory note.

Credit Enhancement Fees – Related Parties
From time to time, the Partnership enters into guarantees of affiliates’ borrowings and provides credit enhancements for the benefit of senior lenders in connection with the Partnership’s affiliates and investments in partnerships (collectively referred to as “guarantees”).  In connection with related party guarantees, as required by the Partnership Agreement and the NASAA Mortgage Program Guidelines, the Partnership obtained an opinion from Jackson Claborn, Inc., an independent advisor, stating that these guarantees are fair and at least as reasonable to the Partnership as a guarantee to an unaffiliated borrower in similar circumstances.

	L.  Concentration of Credit Risk
	Financial instruments that potentially expose the Partnership to concentrations of credit risk are primarily mortgage notes receivable, mortgage notes receivable – related parties and participation interest – related party.  The Partnership maintains deposits in financial institutions that may at times exceed amounts covered by insurance provided by the U.S. Federal Deposit Insurance Corporation (“FDIC”).  The Partnership has not experienced any losses related to amounts in excess of FDIC limits.
	At September 30, 2013, approximately 95% of the outstanding aggregate principal amount of mortgage notes originated by the Partnership are secured by properties located throughout Texas, approximately 3% are secured by properties located in Colorado and approximately 2% are secured by properties located in Arizona.  All of the Partnership’s mortgage investments are in the United States.  At December 31, 2012, approximately 95% of the outstanding aggregate principal amount of mortgage notes originated by the Partnership are secured by properties located throughout Texas, approximately 3% are secured by properties located in Colorado and approximately 2% are secured by properties located in Arizona.  All of the Partnership’s mortgage investments are in the United States.

	M.  Subsequent Events
	Effective October 1, 2013, the maturity date of the UMT loan was further extended to December 31, 2014 and the interest rate was reduced to 9.25% as evidenced by a Fifth Amendment to Third Amended and Restated Secured Line of Credit Promissory Note with UMT.  See Note K, “Related Party Transactions” for further discussion of the Economic Interest Participation Agreement in the UMT Loan.
	Effective October 31, 2013, UDF IV Finance II entered into the Second Amendment to Amended and Restated Loan Agreement with F&M, pursuant to which F&M increased its commitment under the loan from $10.0 million to $15.0 million.  In connection with this Second Amendment to Amended and Restated Loan Agreement with F&M, the Partnership revised the UDF IV Finance II Guaranty to reflect the increase in its guaranty to $15.0 million.   See Note I, “Commitments and Contingencies” and Note K, “Related Party Transactions” for further discussion of the UDF IV Finance II Guaranty on the F&M loan.
	Effective November 4, 2013, UMTH Lending refinanced the UTB-UMTH Lending Loan with City Bank.  In conjunction with this refinance, the Partnership deposited approximately $1.4 million into a deposit account (the “City Bank Deposit Account”) with City Bank for the purpose of providing collateral to City Bank for the benefit of REO PC. UMT Services serves as the general partner for both REO PC and the Partnership’s general partner. The City Bank Deposit Account replaced the UTB Deposit Account.  The Partnership provided City Bank a security interest in the City Bank Deposit Account as further collateral for a loan obtained by REO PC from City Bank (the “City Bank Loan”).  In consideration of the Partnership providing the City Bank Deposit Account as collateral for the City Bank Loan, REO PC agreed to pay the Partnership a monthly fee equal to 1/12th of 1% of the outstanding principal balance of the City Bank Loan at the end of each month. See Note I, “Commitments and Contingencies” and Note K, “Related Party Transactions” for further discussion of the UMTH Lending Deposit Accounts and the Lending Credit Enhancement.

	Basis of Presentation
	The accompanying unaudited financial statements were prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information, with the instructions to Form 10-Q and with Regulation S-X.  They do not include all information and footnotes required by GAAP for complete financial statements.  However, except as disclosed herein, there has been no material change to the information disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, which was filed with the Securities and Exchange Commission  on April 1, 2013 (the “Annual Report”).  The accompanying interim unaudited financial statements should be read in conjunction with the financial statements filed in our Annual Report.  In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting solely of normal recurring adjustments, considered necessary to present fairly our financial position as of September 30, 2013, operating results for the three and nine months ended September 30, 2013 and 2012 and cash flows for the nine months ended September 30, 2013 and 2012.  Operating results and cash flows for the nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
Notes Receivable [Policy Text Block]	'
	Mortgage Notes Receivable and Mortgage Notes Receivable – Related Parties
	Mortgage notes receivable and mortgage notes receivable – related parties are recorded at the lower of cost or estimated net realizable value.  The mortgage investments are collateralized by land and related improvements to residential property owned by the borrowers and/or the ownership interests of the borrower. Currently, the mortgage investments have terms ranging from 5 to 36 months.  None of such mortgages are insured or guaranteed by a federally owned or guaranteed mortgage agency.  We originate and/or acquire all mortgage notes receivable and intend to hold the mortgage notes receivable for the life of the notes.
Loan Participation Interest Related Parties [Policy Text Block]	'
	Participation Interest – Related Party
	Participation interest – related party is recorded at the lower of cost or net realizable value.  Participation interest – related party represents an Economic Interest Participation Agreement with United Mortgage Trust, a real estate investment trust organized under the laws of the state of Maryland (“UMT”), pursuant to which we purchased (i) an economic interest in an $82.0 million revolving credit facility (the “UMT Loan”) from UMT to UDF I, and (ii) a purchase option to acquire a full ownership participation interest in the UMT Loan. See Note K, “Related Party Transactions” for further details.  Our general partner serves as the asset manager for UDF I.  An affiliate of our general partner serves as the advisor to UMT.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	'
	Allowance for Loan Losses
	The allowance for loan losses is our estimate of incurred losses in our portfolio of mortgage notes receivable, mortgage notes receivable – related parties and participation interest – related party.  We periodically perform a detailed review of our portfolio of mortgage notes and other loans to determine if impairment has occurred and to assess the adequacy of the allowance for loan losses.  Our review consists of evaluating economic conditions, the estimated value of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral, and other relevant factors. This review is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
	In reviewing our portfolio, we use cash flow estimates from the disposition of finished lots, paper lots (residential lots shown on a plat that has been accepted by the city or county, but which is currently undeveloped or under development) and undeveloped land as well as cash flow received from the issuance of bonds from municipal reimbursement districts.  These estimates are based on current market metrics, including, without limitation, the supply of finished lots, paper lots and undeveloped land, the supply of homes and the rate and price at which land and homes are sold, historic levels and trends, executed purchase contracts, appraisals and discussions with third party market analysts and participants, including homebuilders. We base our valuations on current and historic market trends on our analysis of market events and conditions, including activity within our portfolio, as well as the analysis of third-party services such as Metrostudy and Residential Strategies, Inc. Cash flow forecasts also are based on executed purchase contracts which provide base prices, escalation rates, and absorption rates on an individual project basis. For projects deemed to have an extended time horizon for disposition, we consider third-party appraisals to provide a valuation in accordance with guidelines set forth in the Uniform Standards of Professional Appraisal Practice. In addition to cash flows from the disposition of property, cost analysis is performed based on estimates of development and senior financing expenditures provided by developers and independent professionals on a project-by-project basis. These amounts are reconciled with our best estimates to establish the net realizable value of the portfolio.
	We charge additions to the allowance for loan losses to current period earnings through a provision for loan losses. Amounts determined to be uncollectible are charged directly against, or “charged off,” and decrease the allowance for loan losses, while amounts recovered on previously charged off accounts increase the allowance.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition
	Interest income on mortgage notes receivable, mortgage notes receivable – related parties and participation interest – related party is recognized over the life of the loan and recorded on the accrual basis.  Income recognition is suspended for loans at the date at which, in the opinion of management, a full recovery of income and principal becomes more likely than not, but is no longer probable, based upon our review of economic conditions, the estimated value of the underlying collateral, the guarantor, adverse situations that may affect the borrower’s ability to pay or the value of the collateral and other relevant factors. Income recognition is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Any payments received on loans classified as non-accrual status are typically applied first to outstanding loan amounts and then to the recovery of lost interest.  As of both September 30, 2013 and December 31, 2012, we were suspending income recognition on 2 mortgage notes receivable with an aggregate unpaid principal balance of approximately $2.2 million.
	We generate mortgage and transaction service revenues and mortgage and transaction service revenues – related parties by originating and acquiring mortgage notes receivable and other loans.  In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 310-20, Receivables – Nonrefundable Fees and Other Costs, we defer recognition of income from nonrefundable commitment fees paid by the borrowers and recognize such amount on a straight-line basis over the expected life of such notes.  In addition, credit enhancement fee income is generated by fees charged to parties for credit enhancements provided to lenders by the Partnership on behalf of the parties.  Income related to credit enhancements is earned as fees are paid, based on the terms of the credit enhancement agreement.  As of September 30, 2013, the Partnership was providing 10 credit enhancements to related parties (see Note K for further discussion).
	The Partnership also expenses acquisition and origination fees (“Placement Fees”) paid to the general partner to provide for processing and origination costs (including, but not limited to, legal fees and expenses, travel and communications expenses, costs of appraisals, accounting fees and expenses, and title insurance funded by us) associated with mortgage notes receivable or participation interest held by the Partnership on a straight-line basis.  As of September 30, 2013 and December 31, 2012, approximately $1.9 million and $2.5 million, respectively, of such net deferred fees are included in mortgage notes receivable. Approximately $530,000 and $698,000 of net deferred fees are included in mortgage notes receivable – related parties as of September 30, 2013 and December 31, 2012, respectively.  As of September 30, 2013 and December 31, 2012, approximately $371,000 and $489,000, respectively, of deferred fees are included in participation interest – related party.  See Note K, “Related Party Transactions” for further details.
Cash Flow Distributions [Policy Text Block]	'
	Cash Flow Distributions
	Cash available for distributions represents the cash funds received by us from operations (other than net proceeds from a capital transaction) that produce proceeds from (i) the repayment of principal or prepayment of a mortgage to the extent classified as a return of capital for federal income tax purposes, (ii) the foreclosure, sale, exchange, condemnation, eminent domain taking or other disposition of a mortgage loan or of a property subject to a mortgage, or (iii) insurance or a guarantee with respect to a mortgage, including, without limitation, interest, points, revenue participations in property appreciation and interest or dividends from interim investments or proceeds from borrowings, if appropriate, less all cash used to pay Partnership expenses and debt payments and amounts set aside to create a retained earnings reserve (currently at 9.5% of our net income; the retained earnings reserve is intended to recover some of the organization and offering expenses incurred in connection with our public offering of our units of limited partnership interest).  Our general partner receives a monthly distribution for promotional and carried interest from the cash available for distributions, in addition to the payments made to our general partner and related parties.  See Note K for further discussion of related party transactions.
	A “carried interest” is an equity interest in us to participate in all distributions, other than distributions attributable to our general partner’s promotional interest, of cash available for distribution and net proceeds from a capital transaction that are distributable under the distribution priority for net proceeds from a capital transaction described below.  If our general partner enters into commitments to investments in mortgages in excess of 82% of the gross proceeds of our public offering of our units of limited partnership interest, our general partner will be entitled to a carried interest equal to (a) 1% for the first 2.5% of commitments to investments in mortgages above 82% of the gross proceeds of our initial public offering, as declared effective on May 15, 2006 pursuant to a Registration Statement on Form S-11 (File No. 333-127891) under the Securities Act of 1933, as amended (the “Offering”) (or if commitments to investments in mortgages are above 82% but no more than 84.5%, 1% multiplied by the fractional amount of commitments to investments in mortgages above 82%), (b) 1% for the next 2% of additional commitments to investments in mortgages above 84.5% of the gross proceeds of the Offering (or if commitments to investments in mortgages are above 84.5% but no more than 86.5%, 1% multiplied by the fractional amount of commitments to investments in mortgages above 84.5%) and (c) 1% for each additional 1% of additional commitments to investments in mortgages above 86.5% of the gross proceeds of the Offering (or a fractional percentage equal to the fractional amount of any 1% of additional commitments to investments in mortgages). By way of illustration, if 85.5% of the gross proceeds of the Offering are committed to investments in mortgages, then our general partner would be entitled to a carried interest of 1.5% (1% for the first 2.5% of commitments to investments in mortgages above 82% of the gross proceeds of the Offering and 0.5% for the next 1% of additional commitments to investments in mortgages above 84.5% of the gross proceeds of the Offering) of any amount otherwise distributable to the limited partners after deduction of any promotional interest payable to our general partner.
	In order for proceeds to be considered “committed” for purposes of calculation and payment of a carried interest, we must be obligated by contract or other binding agreement to invest such proceeds in mortgages, to the exclusion of any other use for such proceeds or no use at all.
	“Investments in mortgages” are the aggregate amount of capital contributions from investors used by us to make or invest in mortgage loans or the amount actually paid or allocated to the purchase of mortgages, working capital reserves (but excluding working capital reserves in excess of 3% of the aggregate capital contributions) and other cash payments such as interest and taxes but excluding our organization and offering expenses, selling commissions, wholesaling fees, marketing support fees, due diligence fees, acquisition and origination fees, and any other front-end fees.
	Our general partner’s “promotional interest” is our general partner’s right to receive:
	·      prior to the return to the limited partners of all of their capital contributions plus an 8% per annum, non-compounding, cumulative return on their unreturned capital contributions, 10% of all cash available for distribution;
	·      following the return to the limited partners of all of their capital contributions plus an 8% per annum, non-compounding, cumulative return on their unreturned capital contributions, 15% of all cash available for distribution; and
	·      following the return to the limited partners of all of their capital contributions plus an 8% per annum, non-compounding, cumulative return on their unreturned capital contributions, 15% of all net proceeds from a capital transaction.
	Monthly distributions are currently paid to our limited partners at a 9.75% annualized return, assuming a purchase price of $20.00 per unit, on a pro rata basis based on the number of days in the Partnership.  Retained earnings would contain a surplus if the cash available for distributions less the 9.5% reserve exceeded the monthly distribution to the general and limited partners.  Retained earnings would contain a deficit if cash available for distributions less the 9.5% reserve is less than the monthly distribution to general and limited partners.  It is the intent of management to monitor and distribute such surplus, if any, on an annual basis.
	The chart below summarizes the approximate aggregate amount of distributions to our general partner and limited partners and the retained earnings deficit as of September 30, 2013 and December 31, 2012:
		As of September 30,				As of December 31,

Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	Fair Value of Financial Instruments
	In accordance with the reporting requirements of FASB ASC 825-10, Financial Instruments-Fair Value, we calculate the fair value of our assets and liabilities that qualify as financial instruments under this statement and include this additional information in the notes to the financial statements when the fair value is different than the carrying value of those financial instruments.  The estimated fair value of restricted cash, accrued interest receivable, accrued interest receivable – related parties, accounts receivable – related parties, accounts payable, accrued liabilities, and accrued liabilities – related parties approximates the carrying amounts due to the relatively short maturity of these instruments. The estimated fair value of mortgage notes receivable, mortgage notes receivable – related parties, participation interest – related party, and line-of-credit approximates the carrying amount since they bear interest at the market rate.
Guarantees, Indemnifications and Warranties Policies [Policy Text Block]	'
	Guarantees
	The Partnership from time to time enters into guarantees of debtors’ or affiliates’ borrowings and provides credit enhancements for the benefit of senior lenders in connection with the Partnership’s debtors and investments in partnerships (collectively referred to as “guarantees”), and accounts for such guarantees in accordance with FASB ASC 460-10, Guarantees.
