The following is a reconciliation of the beginning and ending balances for assets measured at fair value using significant unobservable inputs (Level 3) during the periods ended March 31,June 30, 2018 and December 31, 2017:

Omaha was precluded from making distributions to its investors until its unsecured loan was paid in full. Omaha’s unsecured loan which, as of December 31, 2017 had a balance of $20,859,322, had a maturity date of December 31, 2017. During 2017, Omaha exercised its one option to extend the maturity date to June 30, 2018. Registrant as of the year ended December 31, 2017 had recognized a value in the Omaha investment equal to Registrant’s 30% portion of the equity reported on Omaha’s balance sheet as of December 31, 2017 less a 25% reserve. During the first quarter of 2018, Omaha sold its garden apartment property in Asheville, North Carolina and its garden apartment property in Fresno, California. Net sales proceeds were used first to paying selling expenses and to pay off the mortgage securing each property. Remaining proceeds were used to fully retire the remaining balance of Omaha’s unsecured loan. Registrant as of March 31, 2018 hashad reduced the reserve to 20%.

Except as discussed below, payments of principal are deferred until Registrant’s investment in Sentinel Omaha LLC pays distributions to the Partnership or the Partnership sells Eagle Lake Business Center IV or its investment in Omaha. Distributions from Omaha or net proceeds from the sale of Eagle IV or Omaha would be used first to pay the outstanding principal balance of Note B. If there are no distributions from Omaha prior to the Note B maturity, principal is due at maturity, subject to the above mentioned extensions. On January 30, 2018, the Partnership sent notice to Holder to exercise its first one year option to extend the maturity date to April 29, 2019, which Holder has acknowledged.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FOR THE THREEAND SIX MONTHS ENDED JUNE 30, 2018 AND 2017

General

The consolidated financial statements for the three and six months ended March 31,June 30, 2018 and 2017 reflect the operations of one wholly owned industrial flex property located in Maple Grove, Minnesota and a 30% interest in Omaha.

Registrant’s wholly owned property located in Maple Grove, Minnesota is 100% leased to a single tenant whose lease expires October 31, 2019. The tenant has an ongoing option to terminate the lease under certain conditions. One of the conditions is the payment of an early termination penalty the calculation of which is based on the remaining time period in the lease. Another condition is the tenant must provide notice twelve months prior to the termination. As of March 31, 2018, Registrant has not received any notice from the tenant. The tenant pays fixed base rent which increases approximately 3% each year. The tenant pays directly or reimburses Registrant for all utilities, real estate taxes, insurance and most of the property operating expenses and property management fees.

On July 26, 2018, Registrant and the tenant executed the Fifth Amendment to the lease agreement which extends the expiration date to October 31, 2024. The tenant’s base rent will continue to increase 3% each year and the tenant’s option to terminate the lease early has been eliminated. All other significant terms of the lease remain the same.

Sentinel Omaha LLC’s portfolio consists of 8eight garden apartment properties and one high rise apartment property. Leases generally are for one year or less. Tenants generally pay fixed rent plus utilities used by tenant.

Total revenues increased due to an increase in base rental income and interest income. Base rental income increased $5,000 to approximately $184,000 for the three months ended March 31,June 30, 2018 as compared to the same period in 2017 due to ana scheduled increase in base rent at Registrant’s property located in Maple Grove, MN.

The Registrant reported a net loss from operations of approximately $126,000$127,000 for the three months ended March 31,June 30, 2018, an improvement of $2,000$3,000 as compared to a net loss from operations of approximately $128,000$130,000 for the same period in 2017.

The decrease of loss from operations was due to higher total revenues partially offset by higher total expenses. Total expenses from operations for 2018 increased $4,000$6,000 to approximately $400,000$404,000 from approximately $396,000$398,000 in 2017, due primarily to an increase in management fee expense of $6,000$7,000 partially offset by a decrease in professional feesamortization cost of $2,000.$4,000.

The Registrant reported a net loss from operations of approximately $253,000 for the six months ended June 30, 2018, an improvement of $5,000 as compared to a net loss from operations of approximately $258,000 for the same period in 2017. Net loss from operations consists of net income from the Maple Grove property offset by partnership income and expenses. The decrease of loss from operations was due to higher total revenues partially offset by higher total expenses. Total expenses from operations for 2018 increased $10,000 to approximately $804,000 from approximately $794,000 in 2017, due primarily to an increase in management fee expense of $13,000 and an increase in repairs and maintenance costs of $13,000. This increase was partially offset by a decrease in administrative expenses of $9,000 and a decrease in amortization cost of $4,000.

The Registrant has a 30% non-controlling interest in Omaha that is accounted for on a fair value basis. Net increase in net assets decreased $7,794,000$10,521,000 to approximately $3,705,000$7,426,000 for the three months ended March 31,June 30, 2018 compared to net increase in net assets of approximately $11,499,000$17,947,000 for the same period in 2017. During 2017, Omaha sold its garden apartment property in Daytona, Florida and sold both garden apartment properties located in Fayetteville, North Carolina. Net sales proceeds in each transaction were used to first pay selling expenses and pay off each property’s secured mortgage. Remaining net sales proceeds were used to reduce Omaha’s unsecured loan. During the twelve months ended December 31, 2017, Omaha reported a net increase in the value of its remaining real estate portfolio of $33,815,000. During the quartersix months ended March 31,June 30, 2018, Omaha sold its garden apartment property in Asheville, North Carolina and its garden apartment property in Fresno, California.

During the threesix months ended March 31,June 30, 2018, Omaha reported a net increase in the value of its remaining real estate portfolio of $1,075,000.$2,775,000.

During 2017 the floating rates on Omaha loans increased as short term LIBOR rates increased. The one month LIBOR rate increased from an average of (0.7164%) during December 2016 to an average of (1.4925%) during December 2017. Fixed mortgage interest rates for multi-family properties of similar class and location as Omaha’s portfolio also increased during 2017 from an approximate range of 4.10% to 4.15% in early 2017 to 4.35% to 4.50% near the end of 2017. Mortgage interest rates are expected to continue to increase in 2018 as the U.S. Federal Reserve continues a policy to increase the Federal Funds Rate. Although increases in fixed mortgage rates do not impact the operating cash flow of the Omaha properties directly, increases in fixed and floating rates on commercial mortgage debt can have a negative impact on capitalization rates and the sales prices Sentinel Omaha may achieve in the future.

As noted above, Registrant’s only wholly owned property is 100% leased to a single tenant. If the tenant does not renew or if the tenant exercises its termination option, the Registrant would have no internal source of funds until the space is released to a new tenant or Registrant receives distributions from Sentinel Omaha. Registrant may have to consider that it would be in the best interests of the limited partners to sell its investment in Sentinel Omaha and/or sell its wholly owned property. Registrant would not have considered a sale of its 30% non-controlling investment in Omaha in prior years due to Omaha’s unsecured debt. Selling the investment in Omaha while Omaha had a significant unsecured loan with an upcoming maturity would have likely realized a sale price for the investment that would be heavily discounted reflecting the unsecured debt risk. However, since SentinelSince Omaha has in the past two years paid off the unsecured debt along withand has shown improving performance at the properties, the debt risk is estimated to be lower. The investment in a 30% non-controlling interest would still be valued at a discount due to the lack of liquidity.liquidity and ownership of a non-controlling (minority) interest. Registrant will continue to report a reserve on the value of Omaha on its books but due to the payoff of Omaha's unsecured loan in 2017, the reserve iswas reduced from 25% as of December 31, 2017 to 20% as of March 31, 2018.

This report on Form 10-Q includes statements that constitute "forward looking statements" within the meaning of Section 27(A) of the Securities Act of 1933 and Section 21(E) of the Securities Exchange Act of 1934 and that are intended to come within the safe harbor protection provided by those sections. By their nature, all forward looking statements involve risks and uncertainties as further described in the Registrant’s latest annual report on Form 10-K. Actual results may differ materially from those contemplated by the forward looking statements.

CRITICAL ACCOUNTING POLICIES

The Registrant’s critical accounting policies are described in its Annual Report on Form 10-K for the year ended December 31, 2017. There were no significant changes to such policies in 2018. There are no accounting pronouncements or interpretations that have been issued, but not yet adopted, that Registrant believes will have a material impact on its consolidated financial statements.

Liquidity and Capital Resources

As of March 31,June 30, 2018, the Registrant had cash and cash equivalents of approximately $1,505,000.$1,467,000. These balances are approximately $55,000$17,000 higher than cash and cash equivalents held on December 31, 2017. Cash and cash equivalents increased slightly during the threesix months ended March 31,June 30, 2018 due to cash flow generated from operating activities at Registrant’s wholly owned property partially offset by partnership expenses.expenses and a partial pay down of Registrant’s Note B.

Currently, Registrant’s only source of cash is rental income received from the tenant who leases 100% of the leasable space at Registrant’s wholly owned property in Maple Grove. The tenant reimburses Registrant for real estate taxes, insurance and most of the properties’ operating expenses leaving a significant portion of the base rent received available to fund capital improvements and partnership administrative expenses. A portion of any remaining annual cash flow is used to pay down the principal balance of Note B in accordance with the Loan Agreement while the remaining cash income is retained by Registrant as cash reserves. As part of Registrant and the Holder restructuring the bank loan in 2011, Registrant set aside $500,000 in escrow to be held and used only to pay the costs to re-tenant the space at Registrant’s wholly owned property if Registrant’s tenant defaults on its lease or exercises its right to terminate the lease early or fails to renew. On July 26, 2018, Registrant and the tenant executed the Fifth Amendment to the lease agreement which extends the expiration date to October 31, 2024. The tenant’s base rent will continue to increase 3% each year and the tenant’s option to terminate the lease early has been eliminated. All other significant terms of the lease remain the same.

Total outstanding debt at March 31,June 30, 2018 consists of Note B at $5,726,590.$5,693,876. Under the terms of the Loan Agreement, when Note A was repaid, interest on the Note B stopped accruing. Note B maturesmatured April 29, 2018. Registrant has three one-year options to extend the maturity date if certain conditions are satisfied. On January 30, 2018, the Partnership sent notice to Holder to exercise its first one year option to extend the maturity date to April 29, 2019, which Holder has acknowledged. If the Registrant does not have funds on hand sufficient to repay its indebtedness at maturity, the Registrant may need to refinance such indebtedness with new debt financing or provide necessary funds through equity offering(s) or other sources, if available. The Registrant may be unable to obtain a loan which will be sufficient to retire the existing loan. If it is unable to refinance this indebtedness on acceptable terms, the Registrant may be forced to liquidate its remaining assets upon disadvantageous terms, which could result in losses to the Registrant and adversely affect the amount of cash reserves. If general economic conditions result in higher interest rates at a time when the Registrant must refinance its indebtedness, the Registrant's interest expense could increase, which would adversely affect the Registrant's results of operations and financial condition. The Registrant has no other debt except normal trade accounts payable and accrued investment management fees.

During the quarter, inflation and changing prices did not significantly affect the markets in which the Registrant conducts its business, or the Registrant's business overall.

Registrant anticipates cash flow generated from the property located in Maple Grove and current cash reserves will be sufficient to cover operating and capital improvement costs and other working capital requirements of the Registrant so long as the tenant remains in place.
