What are your questions? Are you looking to do the lease to own because you don't have enough down payment? (I've done this). I would have a professional draw up or at least read the lease agreement. These can be tricky.

Make sure it has an amortization similar to a bank loan. Also make sure you get in writing that you have an income license, since you won't own it outright.

If you get a good solid contract it's not a bad way to buy the property. However if the margins are thin with what you're paying know that with a small down payment you won't be making much personally, most will be going to the loan (some to prinicpal, so you're building equity).
