                           NOTE TO FINANCIAL STATEMENTS


The quarterly financial statements of the Partnership presented herein
are without audit except for balance sheet information as of December
31,1998. Certain information and footnote disclosures normally included
in the annual financial statements have been condensed or omitted from
the accompanying statements.  For such information, reference should be
made to the financial statements and notes thereto included in the
Partnership's annual report on Form 10-K for the year ended December 31,
1998.

In the General Partner's opinion, the unaudited financial statements
reflect all adjustments, which are of a normal recurring nature,
necessary to present fairly the financial position of CSA Income Fund IV
Limited Partnership as of September 30, 1999 and September 30, 1998 and
the results of operations and cash flows for the periods presented
therein.

                                  FORM 10-Q

                  GENERAL PARTNER'S DISCUSSION OF OPERATIONS

Total revenue was $3,397,732 and $4,170,840 and net income was $227,711
and $592,558 for the quarters ended September 30, 1999 and 1998,
respectively.  For the nine months ended September 30, 1999 and 1998,
total revenue was $11,670,923 and $12,563,508, and net income was
$1,133,691 and $2,112,436. The decreases in total revenue and net income were
due primarily to anticipated lease expirations of a few large leases in the
third quarter of 1999. The equipment from these leases is currently being
remarketed, with a portion of the equipment sales completed in the third
quarter.

The Partnership generated cash flow of $11,717,819 from operations and
sales of equipment during the nine months ended September 30, 1999.
During this period, the Partnership used these funds, funds received
from debt financings and cash on hand to acquire additional equipment
of $1,228,380, make payments on notes payable of $7,938,494 and make
distributions to partners of $2,303,527.

The Partnership paid distributions of $.50 per Limited Partnership
unit on the 15th of July, August, and September 1999. CSA Income Fund IV Limited
Partnership increased the October distribution paid on November 15th from an
annualized rate of 6% to 8%. The General Partner will continue to review the
distribution percentage as the Partnership approaches wind-up. Future
distributions will be based on the Partnership's current cash position, as
well as, future cash flow projections.  The General Partner intends to provide
the Limited Partners with the optimal distribution rate throughout the remaining
life of the Partnership.

The General Partner anticipates beginning the wind-up process early next year,
which may continue into calendar year 2002. To date, the Partnership has made
cash distributions to the Limited Partners ranging from 61% to 83% of their
initial investment, depending on when the Limited Partners entered the
Partnership. The objective of the Partnership is to return the Limited
Partner's investment through current distributions and provide a return on this
investment by continued distributions from equipment leasing and ultimate
equipment disposition.

Management reviews the Partnership's projected performance on a periodic
basis. Based on that analysis, the General Partner presently estimates
that the continued cash distributions will return the entire initial
investment of the Limited Partners and a return thereon. However, the
magnitude of the return may be lower than originally anticipated at the
inception of the Partnership. The General Partner will continue to
report on the Limited Partners' return of investment with each cash
distribution and the General Partner intends to pursue additional lease
investment opportunities to increase the Partnership's distributions.
