Vacant lot help

[William Thomas]

Hi all first post on BP. Well here it goes. There is a lot in my neighborhood that had a house that burned down in 2007. In 2009 the lot got sold and permits pull for the property. Now it still sits with nothing on the lot and it's overgrown. I looked up the property on the state website and saw the guy hasn't paid the taxes on the property since 2011. If I want this lot which is the best way to go about doing it? I heard I could pay the taxes and he would have time to pay me back with interest and if he doesn't I would get the rights to it. Any advise would be great thanks again.
