With a lease to own,it is really up to the owner as to whether he or she wants to take this on. However,one of the major components of this arrangement is that at the end of an agreed upon term,you must go to a mortgage lender to get financing. There are other components that go into the deal to help you build up a down payment. You will pay the seller a non refundable deposit(usually 10% to compensate them for taking the house off the market) also your monthly payment must be more than current market rent. The deposit and this extra money are put into an escrow account to build up your down payment. At the end of the specified term,usually 12 mos. but negotiable) you take your down payment and go to the mortgage lender. The drawback is that if you do not go through with the purchase(for example,unable to get financing) you lose your escrow funds. Also if the house goes down in value,you are locked in to the original purchase price. in this situation,the house would not appraise and you could not get funding. So,this can be tricky if there is any doubt that you can get financing at the end of the term. i suggest you confer with a local agent who can discuss this in detail with you and protect your interests. If a lease purchase does not work out,you stand to lose a lot of money,so be careful.
