The average 30-year fixed mortgage rate fell to 6% last week, the lowest level in nearly three years, according to data released Friday. However, the decline has not translated into a significant surge in home affordability, leaving many prospective buyers still priced out of the market.
The shift comes after a period where rates climbed sharply, peaking in late 2023, and coincides with a change in the composition of homeowners with different mortgage rates. As of the end of 2025, the number of homeowners with mortgage rates above 6% surpassed those holding rates below 3%, according to real estate investor Nick Gerli, CEO of Reventure. This marks the end of an era characterized by exceptionally low financing costs for existing homeowners.
The “lock-in effect,” where homeowners were reluctant to sell and forfeit their low rates, has begun to dissipate. This had previously constricted housing supply, driving up prices and intensifying competition for available homes, particularly among first-time buyers. In 2025, the average age of a first-time homebuyer reached 40, and the share of first-time buyers fell to a record low of 21%, according to the National Association of Realtors.
Despite the recent rate decrease, affordability remains a substantial hurdle. The median price of a new home currently stands at $413,595. A 25 basis-point reduction in mortgage rates, from 6.25% to 6%, would allow an additional 1.42 million households to afford a home at that price, according to estimates from the National Association of Home Builders. However, this improvement is largely attributable to the concentration of household incomes within specific affordability thresholds.
Approximately 79.8 million households earn less than $105,880, and an additional 14 million households earn between $105,881 and $132,350. Declining rates have a more pronounced impact on affordability when they fall to near long-term averages, as they are now, due to the fact that they bring more households into these key income ranges. A similar rate cut at higher interest rate levels would have a comparatively smaller effect.
The current situation reflects a broader trend of increasing housing costs relative to income. Both home prices and interest rates have risen sharply in recent years, creating a significant affordability gap. The increase in the cost of homeownership, relative to income changes, is the most substantial since the early 1980s.
The National Association of Realtors acknowledged the challenges, stating that the historically low share of first-time buyers “underscores the real-world consequences of a housing market starved for affordable inventory.”
The Federal Reserve is closely monitoring the impact of potential rate cuts on the housing market. No further announcements regarding future rate adjustments have been made.
