No. Rent to own is a terrible deal for the buyer. Typically:
1. You have to come up with a large sum of money (option) to enter into the agreement. If you default, or ultimately do not purchase the home, you lose it.
2. Your landlord will put a small, pre-determined amount of your monthly rent payment towards your down payment.
3. You may be responsible for all the repairs and maintenance throughout the life of the lease.
4. You may decide after a year that you don't like the area, the house is ultimately to small/large, bills are too much, job make have moved, etc. etc. etc.
You would be better served renting a place within your means traditionally, and saving the down payment on your own. "Rent to own" isn't a way to circumvent using a lender or the approval process, it's simply a way to "force" saving for your down payment. You ALWAYS will have to ultimately qualify for a loan at some point unless you are paying cash, or the owner is lending you the money themselves.
