Rent Credits on RTO

[Lawson Ott]

I am in Indiana, as some of you may know. As far as I can tell, it is not possible to offer rent credits on a Rent - To - Own house and still cover my assets should the buyer act a fool.

creative mind that i am, i am wondering about doing a lease-option so that:
if i rent it to them with the understanding that for every "ON TIME" rent payment, i will mail them a receipt and COUPON for $XXX.xx off the purchase price when (if ever) they decide to buy.

what do you guys think? is this a good idea? or would the law interpret it as rent credits?
