Although most assets would be reported as two sales (average personal percentage and average business percentage), one of the Publications seems to indicate that does not apply to real estate (I don't remember which one right now).

Here is an example if it is reported as one sale:

Purchase price $300,000.   Depreciation of $50,000.  Sale price of $280,000.

In that example, they have $30,000 of "Unrecaptured Section 1250 Gain" (capital gain taxed at ordinary rates, up to 25%).
