New Home Unaffordability Rises Despite Lower Mortgage Rates

New homes became more unaffordable for the typical American household in November 2023. Even though mortgage rates dipped almost two-tenths of percentage point from their October 2023 high, as expected, the median new home sale price rebounded by more than enough to offset both the potential reduction in mortgage payments from those lower rates and the increase in median household income for the month.

The rest of the story is all about the numbers that underlie that outcome. Here's a quick summary of the relevant numbers for November 2023:

  • The average interest rate for a conventional 30-year fixed rate mortgage in the U.S. during the month was 7.44%. This rate was a decrease from the previous month's average mortgage rate of 7.62%.
  • Median household income was $76,791, which was up from October 2023's initial estimate of $76,588.
  • The U.S. Census Bureau's first estimate of the median new home sale price for the month was $434,700. This figure is $19,800 higher than the revised estimate for October 2023.

All these figures together mean the monthly mortgage payment for the median new home sold in November 2023 with zero-percent down would consume 47.2% of the income for a household at the exact middle of the income spectrum in the U.S. The following chart confirms that mortgage payment is well-elevated above the affordability thresholds that lenders set when determining how much they will allow a household to borrow to buy a home.

Looking forward, we already know the average interest rate on a conventional 30-year fixed-rate mortgage dropped to 6.82% in December 2023. We'll find out next month if that will be enough to reverse the upward trend in unaffordability for home ownership that has come to define the Biden era in the United States.
