Good idea to Seller Finance My Vacant Lot?

[Christine Hull]

I own a vacant residential lot and considering offering a land contract (where I keep the deed until the land has been fully paid off by the buyer). One of the potential pitfalls I see is if the buyer decides to build a house on it. If that buyer then defaults on the land payments to me, how would I get my land back if they put a house on it? Yes, this is a lawyer question but thought I'd throw this out there first.
