Non traditional seller takeback: Originial contract sales price was a $230k. Buyer was approved for $198k loan by ABC mortgage company. Contract was amended changing the sales price to $198k. The Settlement Statement will reflect the new contract sales price of $198k only. After settlement, the seller would like the buyer to execute a promissory note and Deed of Trust for $32k and that Deed of Trust would be filed in second lien position. Is such an arrangement legal?
