Legal Question in Real Estate Law in Georgia

You should not be purchasing property at sheriff's sales without legal advice, and your post reveals you made that potentially catastrophic mistake. You cannot convert a sheriff's deed to a warranty deed. When you bought the property, you bought it with all the defects in title it may have had. With a lawyer, you would have done a search and determined if that risk was worth it. You can sell the property, subject to the problems you bought, which may or may not be fixable and may or may not scare off buyers.
