Seller financing differs from a traditional loan because the seller does not actually give the buyer cash to complete the purchase, as does the lender. Instead, it involves issuing a credit against the purchase price of the home. The buyer executes a promissory note or trust deed in the seller’s favor.
The seller may take back a second note or finance the entire purchase if he owns the home free and clear. The buyer makes a sizable down payment and agrees to pay the seller directly every month.
The interest rate on a purchase money note is negotiable, as are the other terms in a seller-financed transaction, and is generally influenced by current Treasury bill and certificate of deposit rates. The rate may be higher than those on conventional loans, and the length of the loan shorter, anywhere from five to 15 years.
