You would pay short term capital gains tax on the sale, so it would depend on your tax bracket. If you are single, you would probably be in the 15% bracket without the sale, and the gain on the sale would probably go into the 25% bracket - so you'd likely pay 15% on some of the gain, and 25% on the part that went over - maybe around 22% overall for the gain on the house sale, plus your normal income tax on your salary.
