Getting ready to put the house back on the market

So our short lived tentants are moving out next weekend and our lovely house will be back on the market. I had a couple of comments on why we decided to lease it out in the first place. Well, with this subprime crisis looming, I thought that there would be some people who would have great cash flow but might have a harder time qualifying for a mortgage. We offered a lease to own option which they were very interested in. The deal was that we would collect the rent and then put $300 a month toward closing costs. At the end of the term, we would "give" back the money, the security deposit and a couple of thousand for the closing costs. Anyway, I thought it was a good deal, but only if you could afford the house.
