June housing-affordability reading leaves buyers a narrow cushion

The national housing-affordability margin narrowed again in June, with the fixed-rate Housing Affordability Index falling to 102.3 after three consecutive monthly declines. The June data were released July 9, 2026, but they remain useful context as mortgage rates moved higher later in July.

The measure is produced by the National Association of Realtors and published through the Federal Reserve Bank of St. Louis’ FRED database. It is not a federal affordability standard. Its value is that it offers a consistent national benchmark for how income, home prices and mortgage rates are changing together.

Affordability fell each month from March through June

The index stood at 112.0 in March, 108.0 in April, 105.1 in May and 102.3 in June. That is a 9.7-point decline from March to June and a 2.8-point drop from May to June.

FRED says a reading of 100 means a family earning the national median income has exactly enough income to qualify for a mortgage on a median-priced home under the index’s assumptions. A reading above 100 indicates more qualifying income than required for that calculation.

The fixed-rate measure assumes a 20% down payment. That assumption is important: Buyers putting down less may face a tougher monthly-cost calculation because of mortgage insurance, a larger loan balance or both. A reading above 100 also does not guarantee that a lender will approve a particular borrower.

Prices and mortgage rates are squeezing purchasing power

The median existing-home price reached $440,600 in June, up 1.8% from a year earlier, according to the National Association of Realtors. That figure is a national midpoint, not the typical price in every state or metropolitan area, but it illustrates the price level used in the national benchmark.

The average 30-year fixed mortgage rate was 6.49% in June, up from 6.44% in May but below 6.82% a year earlier, according to the Realtors’ report citing Freddie Mac data. Even modest rate changes can alter the monthly principal-and-interest payment and the price a household can afford within lender qualification limits.

Rates were higher after the June average. The Associated Press reported that Freddie Mac’s weekly 30-year rate rose from 6.58% to 6.66% in a later update. Those are weekly figures, not the June monthly average, but they provide more current context for people shopping for a mortgage now. Higher rates can reduce purchasing power and cause some buyers to delay a purchase.

Inventory was substantial but growth stalled

National inventory totaled 1.56 million existing homes in June, down 0.6% from May and up 1.3% from June 2025. That represented 4.6 months of supply, unchanged from a year earlier.

More listings can give buyers more choice and reduce pressure on prices. But the June data did not show a large expansion in supply. NAR warned that stalled inventory growth could make longer-term affordability improvement harder if prices accelerate.

The national picture is mixed

Affordability was still better than a year earlier. The index was 95.5 in June 2025 and 102.3 in June 2026, and NAR reported year-over-year improvement in all four regions.

The shorter-term trend is less favorable. The three-month slide has reduced the national cushion above the qualifying threshold, even though the index remains above 100. That makes the latest rate movement especially important because the June index is a lagging monthly measure rather than a real-time estimate of what a buyer will receive from a lender today.

Actual affordability varies with household income, credit history, debt, down payment, taxes, homeowners insurance, mortgage insurance, closing costs and lender rules. Local prices can also differ sharply from the national median.

For prospective buyers, the practical test is to compare current lender quotes and calculate the full monthly payment and cash needed at closing. The national index can show the direction of the market, but it cannot replace a local price comparison or a household-specific estimate.
