         communities and land acquired or disposed by the Company subsequent to

         in the near future and the investment by the Company in a participating
         mortgage note had occurred as of January 1, 1997. The adjustments for
         Prior Offerings assumes the sale of all Common Stock, Preferred Stock
         and Fixed Rate Unsecured Senior Notes (and the related repayment of
         amounts outstanding under the Company's Unsecured Credit Facility)
         subsequent to December 31, 1996 had occurred as of January 1, 1997.

                  communities acquired;
         (ii)     the additional interest expense on debt at weighted average
                  interest rates ranging from 6.5% to 6.8%, incurred for the
                  acquisitions and interest expense on assumed debt;
         (iii)    the depreciation expense based on the new accounting basis of
                  the rental properties based on a 30 year useful life; and
         (iv)     the historical general and administrative expenses, provision
                  for unrecoverable deferred development costs, equity in income
                  of unconsolidated joint ventures, interest income and minority
                  interest of Avalon Properties, Inc.

3.       DISPOSED COMMUNITIES ADJUSTMENTS

         (i)      the elimination of historical operating revenues and expenses
                  of the communities sold;
         (ii)     the reduction of interest expense from the repayment of debt
                  using the net proceeds; and
         (iii)    the elimination of historical depreciation expense of the
                  communities sold.

4.       PROBABLE ACQUISITIONS ADJUSTMENTS

                  acquisitions; and
         (iii)    the depreciation expense based on the new accounting basis of
                  the rental properties based on a 30 year useful life.

5.       PRIOR OFFERINGS ADJUSTMENTS

         Adjustments reflect the reduction in interest expense and additional
         preferred dividends associated with the paydown of amounts outstanding
         under the Company's Unsecured Credit Facility with the proceeds from
         the sale of Common Stock and Preferred Stock, and the change in
         interest expense associated with the sale of Fixed Rate Unsecured 
         Senior Notes subsequent to December 31, 1996.
