VA loans are the easiest loans to use with installment contracts since they were assumable, which means that with the interest rate being assumable, the lender lacks the basis of the interest rate risk under the due on sale clause.It's easy to check with the lender, just ask if the loan is still assumable.

They may decide to buy a house or get a job of high enough quality that they do a background check on them and they need to get the judgment released in order to qualify.

What we are thinking of now doing is hiring a mold inspection company to check out their unit and make sure their claims are valid.
