Advisory fees  totaled approximately $26,000 for the quarter ended September
30, 1997.

The Company also entered into two servicing agreements with the Bank for the
servicing of the commercial and residential mortgage loans.  (The Bank in its
role  as servicer under the terms of the servicing agreements is herein
referred to as the "Servicer").  Pursuant to each servicing agreement, the Bank
performs the servicing of the Mortgage Loans held by the Company, in accordance
with normal industry practice.  The Servicing Agreements can be terminated
without cause upon a thirty day advance notice given to the Servicer.  The
servicing fee is 0.375% of the outstanding principal balance for the
residential mortgage loans and  commercial mortgage loans.

The $20,000 due from affiliates at September 30, 1997 consists primarily of
mortgage loan payments of principal received by the Servicer, for the benefit
of  the Company.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

     The principal business of the Company is to acquire and hold and manage
residential and commercial mortgage loans ("Mortgage Loans") that will generate
net income for distribution to stockholders.  The Company currently intends to
continue to acquire all its Mortgage Loans from The Bank consisting of whole
loans secured by first mortgages or deeds of trust on single-family residential
real estate properties or on commercial real estate properties.

     On July 17, 1997, the Company offered and sold 1,210,000 shares of the
Company's 9.00% preferred stock, Series A, $25 par value per share, totaling
$30,250,000  (the "Series A Preferred Shares"), and sold to D&N Bank  31,781
shares of the Company's common stock, $300 par value per  share, totaling
$30,250,000 (the "Common Stock").  All shares of common stock are held by the
D&N Bank.  The Series A preferred shares are traded on NASDAQ as DNFCP.
        
     The Company used the net proceeds raised from the initial public offering
of the Series A Preferred Shares and the sale of the Common Stock to the Bank,
to purchase from the Bank, the Company's initial portfolio of $60,524,000, of
residential and commercial mortgage loans ("Mortgage Loans") at their estimated
fair values.

     The Bank administers the day-to-day activities of the Company in its role
as Advisor under the Advisory Agreement.  The Bank also services the Company's
Mortgage Loans under each of the Servicing Agreements.

     It is the intention of the Company and the Bank that any agreements and
transactions between the Company, and the Bank, are consistent with market
terms, including the price paid and received for Mortgage Loans, upon their
acquisition or disposition by the Company, or in connection with the servicing
of such Mortgage Loans.  The requirement in the Certificate of Designation
establishing the Series A Preferred Shares that certain actions of the Company
be approved by a majority of the Independent Directors is also intended to
ensure fair dealing between the Company and the Bank.

RESULTS OF OPERATIONS

The Company reported net interest income for the quarter ended September
30,1997 of approximately $898,000.   Interest income from residential and
commercial mortgage loans was $765,000 and $128,000, respectively.  After a
deduction of approximately $26,000 in advisory fees and $11,000 in other
administrative expenses,  the Company reported net income of approximately
$861,000 for the quarter ended September 30, 1997.
                                    - 9 -
<PAGE>   10
The Company reported net income per common share of $10.19 for the quarter
ended September 30, 1997.

For the quarter ended September 30, 1997, the Company paid $537,000 in
preferred stock dividends.  Dividends on the common stock are paid to the Bank
when, as and if declared by the Board of Directors of the Company out of funds
available.  The Company expects to pay common stock dividends at least annually
in amounts necessary to continue to preserve its status as a real estate
investment trust ("REIT") under the Internal Revenue Code of 1986, as amended
(the "Code").


MORTGAGE LOANS

Residential mortgage loans consist of Adjustable Rate Mortgages ("ARMs"), and
Fixed Rate Mortgages ("FRM's").  The commercial mortgage loans consist of fixed
and variable rate loans, a majority of which have balloon payments.
Reinvestments in mortgage loans have been and will continue to be consistent in
maintaining an approximate 90% and 10% ratio between residential and
commercial mortgage loans, respectively.  All Mortgage Loans are  purchased
from the Bank.

For the quarter ended September 30, 1997, the Company purchased replacement
mortgage loans having an outstanding principal balance of approximately
$2,646,000 from the Bank.  In addition, the Company received approximately
$2,755,000 of principal payments on its portfolio from the Servicer.


INTEREST RATE RISK

The Company's income consists primarily of interest payments on Mortgage
Loans.  If there is a decline in interest rates (as measured by the  indices
upon which the interest rates of the residential ARM and variable rate
commercial mortgage loans are based), then the Company will experience a
decrease in income available to be distributed to its shareholders.  There can
be no assurance that an interest rate environment in which there is a
significant decline in interest rates over an extended period of time would not
adversely affect the Company's ability to pay dividends on the Series A
Preferred Shares.

SIGNIFICANT CONCENTRATION OF CREDIT RISK

Concentration of credit risk arises when a number of customers engage in
similar business activities, or activities in the same geographical region, or
have similar economic features that would cause their ability to meet
contractual obligations to be similarly affected by changes in economic
conditions.  Concentration of credit risk indicates the relative sensitivity of
the Company's performance to both positive and negative developments affecting
a particular industry.

Approximately 90% of the Company's total Mortgage Loan portfolio are loans
secured by residential real estate properties located in Michigan.
Consequently, these residential mortgage loans may be subject to a greater risk
of default than other comparable, geographically diverse, residential mortgage
loans in the event of adverse economic, political or business developments and
natural hazards in Michigan.


In addition, the majority of the commercial mortgage properties underlying the
Company's commercial mortgage loans are located in the Detroit metropolitan
area.   Consequently, these commercial mortgage loans may be subject to greater
risk of default in the event of adverse economic, political or business
developments in the Detroit metropolitan area.


LIQUIDITY RISK MANAGEMENT

The objective of liquidity management is to ensure the availability of
sufficient cash flows to meet all of the Company's financial commitments and to
capitalize on opportunities for the Company's business expansion.  In managing
liquidity, the Company takes into account various legal limitations placed on a
REIT as discussed below in Other Matters.

The Company's principal liquidity needs are to maintain the current portfolio
size through the acquisition of additional Mortgage Loans as Mortgage Loans
currently in the portfolio mature, or prepay, and to pay dividends on the
Series A Preferred Shares.  The acquisition of additional Mortgage Loans is
intended to be funded with the proceeds obtained from the  repayment of
principal balances by individual borrowers.  The Company does not have and does
not anticipate having any material capital expenditures.

OTHER MATTERS

As of September 30, 1997, the Company believed that it was in full compliance
with the REIT tax rules and that it will continue to qualify as a REIT under
the provision of the Code.  The Company calculates that:

*    its Qualified REIT Assets, as defined in the Code, are  approxiametly 
     100% of its total assets, as compared to the federal tax requirements 
     that at least 75% of its total assets must be Qualified REIT assets.

*    97% of its revenues qualify for the 75% source of income test and 100% of
     its revenues qualify for the 95% source of income test under the REIT    
     rules.

*    none of the revenue was subject to the 30% income limitation under the   
     REIT rules.


The Company also met all REIT requirements regarding the ownership of its
common and preferred stocks and anticipates meeting the 1997 annual
distribution and administrative requirements.
