ITEM 2.


                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Capital Resources

The Partnership's capital resources consist primarily of its four manufactured
housing communities. On March 25, 1997 the Partnership borrowed $33,500,000 from
Nomura Asset Capital Corporation (the "Financing"). It secured the Financing by
placing liens on its four communities. As a result of the Financing, the
Partnership distributed $30,000,000 to the Limited Partners, which represented a
full return of the original capital contributions of $1,000 per unit.

Liquidity

As a result of the Financing, the Partnership's four properties are mortgaged.
At the time of the Financing, the aggregate principal amounts due under the four
mortgage notes was $33,500,000 and the aggregate fair market value of the
Partnership's mortgaged properties was $53,200,000. The Partnership expects to
meet its short-term liquidity needs generally through its working capital
provided by operating activities.

The Partnership's long-term liquidity is based, in part, upon its investment
strategy. The properties owned by the Partnership were anticipated to be held
for seven to ten years after their acquisition. All of the properties have been
owned by the Partnership more than ten years. The General Partner may elect to
have the Partnership own the properties for as long as, in the opinion of the
General Partner, it is in the best interest of the Partnership to do so.

The Partnership has a renewable $600,000 line of credit with National City Bank
of Michigan/Illinois (formerly First of America Bank). The interest rate, on
such line of credit, floats 180 basis points above 1 month LIBOR, which on March
31, 1999 was 4.94%. The sole purpose of the line of credit is to purchase new
and used homes to be used as model homes and offered for sale within the
Partnership's communities. Over the past three years, sales of the new and used
model homes has been growing and the General Partner believes that continuing
the model home program is in the best interest of the Partnership. As of March
31, 1999, the outstanding balance on the line of credit was $469,523.

Net Cash from Operations available for aggregate distributions to all Partners
in UMHCIF during the quarter ended March 31, 1999 amounted to $476,752. The
amount available during the same period in 1998 was $320,585. Management
considers Net Cash from Operations to be a supplemental measure of the
Partnership's operating performance. Net Cash from Operations is defined to mean
net income computed in accordance with generally accepted accounting principles
("GAAP"), plus real estate related depreciation

                                      -7-
<PAGE>   8

and amortization. Net Cash from Operations does not represent cash generated
from operating activities in accordance with GAAP and is not necessarily
indicative of cash available to fund cash needs. Net Cash from Operations should
not be considered as an alternative to net income as the primary indicator of
the Partnership's operating performance or as an alternative to cash flow as a
measure of liquidity.

The quarterly Partnership Management Distribution due and paid to the General
Partner for the first quarter was $143,250, or one-fourth of 1.0% of the most
recent appraised value of the properties held by the Partnership.
($57,300,000 x .01 = $573,000 / 4 = $143,250).

The cash available after payment of the Partnership Management Distribution
amounted to $333,502. From this amount, the General Partner elected to make a
total distribution of $84,350 for the first quarter of 1999, 80.0% or $67,500
was paid to the Limited Partners and 20.0% or $16,850 was paid to the General
Partner.

While the Partnership is not required to maintain a working capital reserve, the
Partnership has not distributed all the cash generated from operations in order
to build cash reserves. For the quarter ended March 31, 1999, the Partnership
added $249,152 to reserves. During the same quarter in 1998, the Partnership
added $106,085 to cash reserves. The amount placed in reserves is at the
discretion of the General Partner.

Results of Operations

OVERALL, as illustrated in the tables below, the four properties enjoyed a
combined average occupancy of 97.6% (1,780/1,824 sites) at the end of March
1999, versus 97.5% a year ago. The average monthly rent in March 1999 was
approximately $405, or 2.8% more than the $394 average monthly rent in March
1998.

COMPARISON OF QUARTER ENDED MARCH 31, 1999 TO QUARTER ENDED MARCH 31, 1998

Gross revenues increased $109,115, or 5.2%, to $2,190,982 in 1999, as compared
to $2,081,867 in 1998. The increase was the result of the increase in average
monthly rents. (See table on previous page.)

As described in the Statements of Income total operating expenses decreased
$41,552, or 2.1%, to $1,948,230 in 1999, as compared to $1,989,782 in 1998. The
decrease was primarily the result of lower administrative expenses and lower
interest payments related to the Partnership's mortgage debt.

As a result of the foregoing factors, net income increased to $242,752 as of
March 31, 1999 from $92,085 as of March 31, 1998.


MANAGEMENT EXPENSES

Net Partnership management expenses paid during the quarter amounted to $59,036.
Gross expenses of $68,284 (data processing, accounting and legal expenses,
office supplies and wages to employees of the Partnership) were partially offset
by income of $9,248 generated by interest on the Partnership's reserves and
transfer fees. The figures for last year's first quarter were $115,183, $122,573
and $7,390, respectively.
