Home affordability improved slightly in June as both mortgage rates and monthly housing costs eased, even though median household income slipped a touch. The median monthly housing cost fell to $2,397, down $27 from May, while the gap between what households earn and what they need to comfortably afford a home narrowed to its tightest level since March.
At a Glance
- Median monthly housing cost dropped to $2,397 in June, down from $2,424 in May
- The home affordability index rose to 0.88 from 0.87
- Monthly income needed to afford a median priced home fell to $7,991
- The affordability gap narrowed to $980, the smallest since March
- Typical home price slipped to $369,147 while average mortgage rates fell 12 basis points
Why the Numbers Moved
Two things happened at once in June: home prices eased and mortgage rates cooled. The typical home price dropped $630 to $369,147 from $369,777 in May, a modest but real pullback. At the same time, average monthly mortgage interest rates fell by 12 basis points. Combined, those two shifts trimmed the monthly cost of principal and interest enough to pull the overall housing cost down by $27, to $2,397. That figure includes principal, interest, taxes and insurance, the standard PITI calculation lenders use to assess what a household actually pays each month.
The housing cost to income ratio, which measures what share of income goes toward housing, improved to 34.19% from 34.56%. That is still well above the 30% threshold the federal government uses to define a household as cost burdened, a standard that traces back to research from the Harvard Joint Center for Housing Studies. Anyone tracking affordability month to month should treat that persistent overshoot as the real story: a small improvement doesn't erase a structural affordability problem, it just softens it marginally.
What the Affordability Index Actually Measures
The affordability index compares housing costs against income, with a reading of 1.0 or higher signaling that housing is broadly affordable and anything below 1.0 signaling the opposite. June's reading of 0.88 means the typical household is still short of the income needed to keep housing costs at or below that 30% benchmark. It's an improvement over May's 0.87, but it's worth being skeptical of how much weight to put on a one point move in an index that has sat below 1.0 for an extended stretch. A single month's uptick doesn't establish a trend, and the index remains solidly in unaffordable territory.
Quick Facts
- June housing cost ratio: 34.2%, above the 30% federal affordability threshold
- Income required to afford a median priced home: $7,991 per month, down from $8,082 in May
- Actual median monthly household income: $7,011, down $5 from May's $7,016
- Narrowest affordability gap on record: $649, in September 2024 when mortgage rates hit a recent low
- Average affordability gap since June 2023: $1,128
The Income Side of the Equation
Affordability isn't just about home prices and mortgage rates. Income matters just as much, and June's data shows income actually moved in the wrong direction, if only slightly. Median monthly household income came in at $7,011, down $5 from May. That's a rounding error in isolation, but it underscores that the improvement in affordability this month was entirely a function of falling costs, not rising paychecks. If income had kept pace or grown, the affordability gap would have narrowed by more than it did.
The gap itself, the difference between what a household actually earns and what it would need to earn to spend no more than 30% of income on housing, fell to $980 in June. That's down from a wider gap in prior months and marks the narrowest reading since March. Still, $980 a month is not trivial. That's money a median income household would need to find, on top of current earnings, just to bring housing costs into what regulators consider a sustainable range. For context, the gap has averaged $1,128 since June 2023, so June's reading sits modestly below that longer run average.
Breaking Down the Monthly Housing Bill
The components of the typical monthly payment shifted only at the margins between May and June, but the direction is instructive.
| Date | Mortgage Payment (Principal and Interest) | Property Taxes | Insurance | Monthly Total Cost |
|---|---|---|---|---|
| 2025 to 06 | $1,945 | $237 | $215 | $2,397 |
| 2025 to 05 | $1,972 | $237 | $215 | $2,424 |
Property taxes and insurance held flat month over month, which means the entire $27 decline in total housing cost came from the principal and interest line, the piece most sensitive to both home price and mortgage rate movement. That's a useful reminder for anyone modeling their own numbers: taxes and insurance tend to be sticky in the short term, while the rate environment and purchase price are where the real swings happen.
Insurance and property taxes together still add roughly $450 a month to the typical housing bill, a cost that doesn't show up in headline mortgage rate discussions but meaningfully affects the total burden. Homeowners and prospective buyers evaluating affordability should factor in these carrying costs rather than anchoring purely on the advertised mortgage rate.
Rate Shopping and the Cost of Not Comparing Lenders
The 12 basis point decline in average mortgage rates during June is a market wide figure, but individual borrowers have more control over their own rate than that number suggests. Freddie Mac data cited in industry research indicates borrowers who obtain at least four rate quotes save an average of $600 to $1,200 annually compared with those who accept the first offer. Separate research from the Federal Reserve Bank of Philadelphia found that getting even one additional rate quote produces an 18 basis point reduction on average, rising to a 28 point reduction for lower income borrowers specifically.
That's a meaningful spread when set against the market's 12 basis point monthly movement. In other words, the difference between shopping around and not shopping around can dwarf the natural month to month drift in national average rates. Anyone using an index like this one to time a purchase should weigh that against the more controllable variable: how many lenders they actually get quotes from before signing.
How the Data Is Built and Where It Could Mislead
The affordability figures rely on the Zillow Home Value Index for typical home prices, chosen because it updates frequently and spans single family homes, condos and co-ops. Mortgage rates come from daily rate reporting tied to Zillow data, based on loans with a loan to value ratio of 80% or less (meaning at least a 20% down payment) and credit scores in the 680 to 739 range. That's a specific and fairly narrow borrower profile. Buyers with smaller down payments, lower credit scores, or jumbo loan needs will see materially different rates and payments than the ones reflected in this index, so the headline numbers should be read as a benchmark rather than a personal estimate.
Property tax estimates come from Tax Foundation data averaged across states, and insurance estimates come from Insurify. Median income is built from Census Bureau American Community Survey data for 2023, adjusted upward using Bureau of Labor Statistics wage growth figures to approximate current income levels. That adjustment introduces some lag risk: if wage growth has decelerated or accelerated faster than the BLS series captures, the income figure could be running slightly ahead of or behind reality. It's a reasonable methodology, but worth flagging for anyone treating the $7,011 income figure as precise rather than estimated.
What This Means for Buyers Weighing Their Options
A household can check its own position using the same logic: divide total monthly housing payment, including principal, interest, taxes and insurance, by monthly income. If that ratio exceeds 30%, the household is cost burdened by the same standard used in this analysis. Prospective buyers can run their own numbers through a mortgage calculator to see how a specific rate and price would affect that ratio before committing.
Whether June's improvement holds into the summer will depend on whether mortgage rates continue easing and whether home prices keep drifting down in the face of still constrained income growth. The $980 gap is the smallest since March, but it remains well above the $649 low from September 2024, and income itself actually lost ground this month. That combination suggests affordability is improving at the margins rather than resolving, and buyers weighing a purchase should treat this month's data as a modest tailwind rather than a green light.
