The NAHB priced-out model uses the ability to qualify a mortgage to measure housing affordability, because most home buyers finance their new home purchase with conventional loans, and because convenient underwriting standards for these loans apply.
According to the association, the standard it adopts for its priced-out estimates is that the sum of the mortgage payment (including the principal amount, loan interest, property tax, homeowners’ property, and private mortgage insurance premiums (PITI), is no more than 28% of monthly gross household income.
Using the NAHB’s methodology, 39 million (about 31%) of the 126.7 million U.S. households can afford to buy a new median-priced home at $412,505 in 2022. But a $1,000 home price increase will take about 117,932 households out of the market.

Both the NAHB and National Lumber and Building Material Dealers Association continue to lobby the White House and Congress over the issue of housing affordability and the need for corrective measures.
