No. you can't claim losses on the sale of personal use property.

But if it were a gain, I would have to claim a capital gain?

Stick to your other question.  You said it was a rental?

Your question was answered in the other post ... yes, a gain is taxable .  If you sell a rental then not only is the gain taxable but you also MUST recapture the depreciation allowed or allowable even if you didn't take any.
