Consider a shared-appreciation mortgage (SAM) on a $250,000 mortgage with yearly payments. Current market mortgage rates are high, running at 13%, of which 10% is annual inflation. Under the terms of the SAM, a 15-year mortgage is offered at 5%. After 15 years, the house must be sold, and the bank retains $400,000 of the sale price. If inflation remains at 10%, what are the cash flows to the bank? To the owner?
