Homebuyers in the country’s most expensive metro areas just got more room to borrow at conventional rates. The Federal Housing Finance Agency set the 2026 baseline conforming loan limit at $832,750 for single-unit properties, up from $806,500 in 2025. In high-cost counties across California, New York, and the Washington, D.C., region, the ceiling rises to $1,249,125, calculated as 150% of the baseline. The annual adjustment, driven by a 3.26% increase in national home prices, determines which borrowers qualify for loans backed by Fannie Mae and Freddie Mac and which get pushed into the jumbo market with its higher rates and stricter underwriting.
How the 3.26% home-price gain reshaped 2026 borrowing power
The size of the annual increase ties directly to FHFA’s House Price Index. The agency used the nominal, seasonally adjusted expanded-data HPI to measure how average U.S. home values changed over four quarters, arriving at the 3.26% figure that produced the $832,750 baseline. That formula is not discretionary. It follows the Housing and Economic Recovery Act, or HERA, which requires FHFA to recalibrate the limit each year based on measured price appreciation. The high-cost ceiling then locks in at exactly 150% of whatever baseline the index produces.
For a buyer in a county where median prices sit between the old and new baselines, the practical effect is immediate. A loan that would have required jumbo terms in 2025 can now be underwritten as a conforming mortgage, typically carrying a lower interest rate and smaller down-payment requirement. In counties where local median prices push the limit all the way to the 150% cap, such as Los Angeles and parts of the New York metro area, borrowers can now access conforming pricing on loans up to $1,249,125. Last year those same counties topped out at $1,209,750, as FHFA detailed in its 2025 release.
The gap between conforming and jumbo rates varies by lender and credit profile, but even a quarter-point difference on an $800,000 mortgage translates to tens of thousands of dollars over the life of the loan. That is the core reason the limit adjustment matters to individual households, not just to the agencies that guarantee the paper. A slightly larger conforming window can also expand the pool of eligible buyers in expensive neighborhoods, potentially supporting prices at the margin in markets where affordability is already stretched.
Because the HERA formula is backward-looking, based on the prior year’s price data, the 3.26% increase does not signal where prices are headed in 2026. It simply codifies what has already happened in the housing market and translates it into new borrowing thresholds. If home prices were to flatten or fall in a future year, the statute would allow for a smaller increase or even a freeze in the baseline, though FHFA has historically applied the formula consistently rather than trying to smooth market cycles.
Which counties hit the $1,249,125 ceiling and why others did not
FHFA publishes downloadable county-by-county files on its data hub that show exactly where each county’s limit lands. Those loan-limit tables confirm that not every county reaches the 150% cap. The formula assigns a county its own limit based on local median home values, but that limit cannot exceed 150% of the baseline and cannot fall below the baseline itself. Counties in expensive coastal markets, where median prices far exceed the national figure, consistently hit the ceiling. Los Angeles County and New York County both reached the prior cap of $1,209,750 for 2025, and they will sit at $1,249,125 for 2026 under the updated schedule.
Counties in less expensive regions simply adopt the $832,750 baseline because their local median prices do not justify a higher figure under FHFA’s methodology. In many parts of the Midwest and South, for example, typical sale prices remain far below the national average, leaving ample room between prevailing home values and the conforming cap. In those markets, the limit change is more symbolic than transformative: it increases theoretical borrowing capacity but does not immediately pull a large number of buyers out of the jumbo category because relatively few were near the old ceiling to begin with.
There is also a middle tier of counties where the limit falls somewhere between the baseline and the 150% maximum. These include fast-growing suburbs around major job centers, mountain resort communities, and select Sun Belt metros where home values have climbed quickly but not enough to trigger the full high-cost designation. In these areas, the 3.26% adjustment still raises the local cap and can meaningfully expand access to conforming loans, especially for move-up buyers and households purchasing new construction.
For lenders and real estate professionals, the 2026 limits will shape product offerings and marketing strategies over the next year. Mortgage originators often design rate sheets, underwriting overlays, and lock policies around the conforming thresholds, while builders and listing agents in high-cost markets may price homes with an eye toward keeping them inside the most favorable financing bands. For borrowers, the key takeaway is straightforward: checking the new county-specific limit before shopping can clarify how much they can borrow with conforming terms and whether stretching into jumbo territory is worth the added cost and documentation burden.
