Incidentally, the $80,000 houshold income, as would be represented at the 75th percentile in our region, could swing a mortgage of $310,000, leading to the $345,000 median housing price. That is, of course, assuming no move-up equity and the aforementioned 6% mortgage interest rate. At an 8% interest rate the PITI payment drops to support a $260,000 mortgage and the sale price (median) drops to $290,000. Should the sky fall and we end up with 10% interest rates again that mortgage drops to ~$215,000 and a sale price of ~$240,000.
