As housing affordability remains a critical challenge across the country, mortgage rates continue to play a central role in shaping homebuying power. Mortgage rates stayed elevated throughout 2023 and early 2024. Recent data, however, shows a slight decline in mortgage rates. Even modest declines can have a significant impact on housing affordability, pricing more households back into the market. New NAHB Priced-Out Estimates show how price increases affect housing affordability in 2025 and how interest rates affect the number of households that can afford a median priced new home.
At the beginning of 2025, with the average 30-year fixed mortgage rate at 7%, around 31.5 million households could afford a median-priced home at $459,826. This requires a household income of $147,433 by the front-end underwriting standards[1]. In contrast, if the average mortgage rates had remained at the recent peak of 7.62% in October 2023, only 28.7 million households would have qualified. This 62-basis point decline has effectively priced 2.8 million additional households into the market, expanding homeownership opportunities.
The table below shows how affordability changes with each 25 basis-point increase in interest rates, from 3.75% to 8.25% for a median-priced home at $459,826. The minimum required income with a 3.75% mortgage rate is $110,270. In contrast, a mortgage rate of 8.25%, increases the required income to $163,068, pushing millions of households out of the market.
As rates climb higher, the priced-out effect diminishes. When interest rates increase from 6.5% to 6.75%, around 1.13 million households are priced out of the market, unable to meet the higher income threshold required to afford the increased monthly payments. However, an increase from 7.75% to 8% would squeeze about 850,000 households out of the market.
This exemplifies that when interest rates are relatively low, a 25 basis-point increase has a much larger impact. It is because it affects a broader portion of households in the middle of the income distribution. For example, if the mortgage interest rate decreases from 5.25% to 5%, around 1.5 million more households will qualify the mortgage for the new homes at the median price of $459,826. This indicates lower interest rates can unlock homeownership opportunities for a substantial number of households.
