There were no preferred shares outstanding during any of the periods
above,
and therefore the ratio of earnings to combined fixed charges and preferred
shares dividend requirements would have been the same as the ratio of
earnings
to fixed charges for the periods indicated.

(1)   Mid-Atlantic Realty Trust, the "Company", is the successor to the
operations of BTR Realty, Inc. , the predecessor company. The
computations
above use the Consolidated Financial Statements of Mid-Atlantic Realty
Trust
for the years ended December 31, 1997, 1996, 1995, and 1994 and the
period 
September 11, 1993 (commencement of operations) through December 31,
1993, 
and also includes the Consolidated Financial Statements of BTR Realty,
Inc.
for the periods January 1, 1993 through September 10, 1993.

(2)   Effective January 1, 1996, the Company changed its reporting of 
gains
or losses on sales of properties held for sale. During the year ended
December 31, 1995, and previously, gains or losses on sales of properties
held
for sale had been included in revenues in the consolidated statement of
operations and were therefore included in earnings from operations.  The
Company is not in the business of buying land for resale.  Therefore,
management believes gains or losses on sales of properties held for sale
should not be included in earnings or losses from operations, and should be
an
adjustment to earnings from operations to arrive at net earnings.  The
comparative prior year earnings (losses) from operations have been
reclassified to reflect this change.

(3)  Effective January 1, 1996, the Company changed its reporting of
amortization of deferred financing costs. During the year ended December
31,
1995, and previously, the annual amortization of deferred financing costs
was
reported in the depreciation and amortization of property and improvements
expense line in the consolidated statements of operations.   In 1996, the
Company began reporting the amortization of deferred financing costs in
the
interest expense line in the consolidated statement of operations.  The
comparative prior year interest expense amounts above have been
reclassified
to reflect this change.

(4) Amounts reflect a one-third portion of rentals, the portion deemed
representative of the interest factor.
