Rent to own is BS. All that happens is that you are given credit for the money paid to the principle of the loan while you were a renter. If it is a loan less then 10 years old then they are basically making your first mortgage payment for you after you have been paying them rent for 2 years and allowing them to own a house for free while it appreciates in value and since you are trying to get that little pittance of money that they are promising to give you they will demand a higher price for the house that you have been paying for already. Just buy a house right off the bat and don't deal with A hole scammers.
