The Lease/Option in my opinion is not the same as Rent to Own.
My past experience with 'Rent to Own' is simple. Only about 5% of the time will the
renter stay long enough to complete the required down payment to obtain the home, and the rental amount is increased to accommodate a portion of the rental going toward the down payment.
Thus all the cash you pay into the rent, over and above the true rent .. will be lost, should you not stay there long enough to actually complete the time required to accumulate the 'down' payment from the additional rent proceeds.
You usually do not get that 'rent' money back.
I suggest you just find a rental and save toward a purchase. Your money will be better spent.
