I think a lot of potential buyers with bad credit view the lease option as a pathway to home ownership. It rarely works that way as most lease options end up being just leases.
Keep in mind that if you do not qualify for a loan before your option term expires you will have spent a lot of extra money for a lease option on a home you will not be able to purchase. Since tenants typically don't have a home inspection or do a title search before entering a lease option, you may find the homes has issues you don't know about until later on. You can also find yourself making the option and rental payments on time each month only to find out the landlord/seller is in foreclosure.
Rent to own scams are common, so look at a lease option situation very carefully.
