Freddie Mac's results of its Primary Mortgage Market Survey® shows that "Mortgage rates set several record lows over the last few months and have remained low into September. While there is room for rates to decrease even more, higher home prices and low inventory could potentially stifle the high demand that we’ve been seeing."
