Get the house back on the market and speak with your agent about how you can better pre-qualify a potential buyer.

Again, depending on the reason the buyer walked I would recommend (after you and your agent determine what's happening with the deposit) that you sign a mutual release and get on with getting your home back on the market. For future reference make sure you have a sizeable deposit to hopefully avoid a repeat.
