If I sold a rental property , I need to pay taxes? or if I use this money for pay my main house and other rental property still I need to pay taxes .

[Hal_Al · Accepted solution]

Yes. It doesn't matter what you did with the proceeds. The sale is reportable and will result in a reportable  capital gain or loss. A portion will be depreciation recapture; which is not subject to favorable long term capital gains tax rates.
