You will owe tax on the capital gains, which is not the same as the cash you get out.
Your capital gains is the difference between the adjusted cost basis and the net selling price.
The net selling price is the actual selling price minus transfer taxes, other legal fees, real estate commission, and buyer's closing costs if you pay them. (Minor pre-sale repairs and staging costs don't count, unfortunately.)
The adjusted cost basis is the price you paid, plus certain closing costs that were part of the original purchase, plus the cost of any permanent improvements you made to the property over the years, and minus any depreciation you took or could have taken when you were renting it out, and minus any casualty loss you may have claimed.
The depreciation recapture is taxed at 25% and the rest of the gain is taxed at the 15% rate for long term capital gains (for most taxpayers).
Considering the tax cost of selling after the deadline, you might want to drop your listing price to get an earlier sale, or offer to pay closing costs. Ask your real estate agent how to get a quicker sale with this in mind.
