Need help with evicting a buyer with Warranty Deed

[Harsh Desai]

I created a warranty deed along with a promissory note on a low income property in High Point and sold it to a buyer. The buyer didn't make the payments and at one point went to jail abandoning the property. Now the buyer comes back after almost a year and wants the property back saying that the warranty deed is still in his name (which it is). How do I get this person to drop all their rights to the property? So far I have had to pay the property taxes myself and also pay for cleaning the property when it was left in a bad state.

Really desperate for help.
