The latest NAHB/Wells Fargo Cost of Housing Index, released in early March 2026, shows nahb data maps modest gains in housing affordability for 2025 as prices ease and mortgage costs retreat in the second half of the year. The index tracks whether a typical family can afford a median priced home by measuring the share of income needed for a monthly mortgage payment.
The improvement is modest, but it marks a departure from the sequence of early 2020s tightness. In 2023 the index showed the affordability squeeze at its worst, with households spending a larger slice of income on mortgage costs. By late 2025, declines in new home prices and a moderation in rates contributed to a softer overall burden for buyers.
Key numbers from the nahb data maps modest gains in 2025
- The fourth quarter of 2025 shows the average family dedicating 34 percent of income to a mortgage for a median priced, new single family home. That is up from 34 percent in the second quarter and down from 35 percent in the third quarter, signaling a flat but improved affordability trajectory.
- Across 2023, the index peaked at 41 percent, underscoring how far affordability had fallen before the late-2020s stabilization.
- New home prices cooled in December 2025, with the median price for new homes sold dropping 2.0 percent year over year to $414,000 from $423,000 a year earlier.
- Mortgage rates have eased, with a typical 30-year fixed rate around 6.0 percent in late 2025, down from a high near 6.7 percent reached last May.
- Existing homes also saw relief, with the share of income needed falling from 37 percent in mid-2025 to 34 percent by the end of the year.
- Regionally, the Sun Belt continues to face an oversupply in new homes balanced against a wave of speculative construction following the pandemic, a dynamic that keeps affordability uneven across markets.
What the data means for buyers and lenders
For homebuyers, the nahb data maps modest gains in affordability for 2025 signal gradual relief rather than a dramatic turn lower in monthly payments. The improvement hinges on a combination of price concessions from builders and a retreat in financing costs that had previously weighed on demand.
Lenders and policy watchers say the stabilization in rates and prices could help stabilize demand in 2026, though affordability will remain a work in progress in many metros. Builders have continued to offer buyer incentives in markets where price relief is most needed, underscoring the ongoing balancing act between supply and demand.
Regional dynamics and market implications
The Sun Belt’s growth story remains mixed. While some cities benefit from job and population gains, others struggle with a backlog of new homes tied to rising construction costs and financing constraints. In markets with meaningful oversupply, price cuts and incentives continue to be a tool to move inventory, which in turn helps the nahb data maps modest gains across the broader index.
Analysts note that the regional divergence is likely to persist into 2026, limiting the breadth of affordability gains. Homebuyers in southeastern and southwestern markets may see smaller improvements than those in areas with tighter inventories, where price declines and rate relief can translate into meaningful monthly savings.
Industry voices and the outlook for 2026
Robert Dietz, chief economist at NAHB, commented on the latest results: the data 'points to a turning point for affordability, though gains remain modest and uneven across markets'. His assessment aligns with broader market signals that while purchasing power is improving, the pace varies widely by region and property type.
Real estate economists expect the trend to continue into 2026 with rates expected to hold near current levels for most of the year and home price growth staying modest. Some forecasters caution that any uptick in inflation or a shift in mortgage rate expectations could compress the gains seen in 2025.
What to watch next
- Mortgage rate momentum: If rates stabilize around 6.0 percent, monthly payments could drift lower as prices fail to surge above inflation-adjusted levels.
- Price dynamics: A continued cooling in new-home prices would provide a deeper lift to the nahb data maps modest gains and could expand buyer enrollment in 2026.
- Supply shifts: Persistent oversupply in the Sun Belt could dampen regional affordability gains, while tight markets elsewhere may see more pronounced relief.
- Policy environment: Any changes to mortgage underwriting standards or housing subsidies could impact the pace of affordability improvements.
Closing view
The nahb data maps modest gains over 2025 offer a cautious narrative for buyers: affordability is inching higher, but the path remains gradual and uneven. For households seeking a hinge point to begin homeownership, the year ahead could bring incremental relief rather than a sudden reset. As the data mature into 2026, lenders, builders and policymakers will watch whether this modest improvement translates into stronger demand and healthier housing markets.
In short, the nahb data maps modest gains reflect a cautious recovery in housing affordability, with a clear message: relief is on the way, but it will take time to spread evenly across regions and price tiers.
