A CFD is not the way to go, but putting in the offer that the Realtor gets the commission at signing an installment purchase, by modifying the listing agreement, will improve your chances.A listing doesn't have to be made for an installment offer to be made......unless the listing says no installments or specifies the offers to be accepted.

There is a spray foam that can be installed too, but that will be two to four times the price of other alternatives.
