Capital gains only hits a percentage (20% or less) of the price increase. Yeah, it sucks. But it shouldn’t wipe out any profit. Unless you played risky games with the depreciation…It has paid for my daughters college, with a little left over. You can make money on them but I'd have to have 100 units to make a living at it. At that point it would be a full time job.
Sad part is, capital gains taxes could easily wipe out any money you make on the sale of the property.
