thank you njrookie, please one more question below

Is this right?
your net sales price of $500,000 and subtracting your adjusted tax basis of $290,920 (which is original cost, $400,000, minus accumulated depreciation, $109,080). The result is your $209,080 capital gain. At the 15 percent tax rate, your long-term capital gain tax liability is $31,362.

My understanding is just 500k minus cost base 400k=100k as capital gain, so 100k X 20% as long term capital gain tax, then recap $109080 X25% as recap tax, Right?
