if so, make sure you really understand what is involved in that kind of arrangement.
There are not a lot of options out there as most sellers who want to sell, and can sell, sell not, not ater. This arrange favors the seller NOT the buyer.
If you're not qualified for a loan now, you better make sure you are at the end of the lease term, or you stand to LOSE money.
You will be expected to give an upfront deposit and also pay rent over and above the usual rent (only that "extra" rent will be applied to the purchase, not the entire rent you have paid in) - usually, that extra rent and deposit is forfeited if you do not buy the home for ANY reason.
So, if you have financial issues, I suggest working on them first, renting now in the normal way, and then buying when you know you will be able to qualify for a loan.
You will also have a full selection of homes from which to choose.
