Conforming vs. Jumbo Loans
There's a dollar line running through every mortgage market. At or below it, your loan is conforming; above it, it's a jumbo. That single line changes who can buy your loan — and the rate can move right at it.
Where the line is
For 2026, the baseline conforming limit for a one-unit home in most of the U.S. is $832,750 — up 3.26% from 2025's $806,500. High-cost counties get a higher "high-balance" ceiling, up to $1,249,125. The FHFA resets these every November to track home prices, so the exact figure drifts year to year; the current values are published on the FHFA's conforming loan limit page.
Why the line matters
A conforming loan fits Fannie Mae / Freddie Mac rules, so the lender can sell it into the agency market. That liquidity is why conforming loans usually carry the market's lowest, most standardized rates — it's the headline rate our board tracks. A jumbo can't be sold to the agencies, so the lender (often a bank) keeps the loan and its risk on the books, and prices and qualifies it on its own terms.
Jumbo isn't automatically more expensive
The intuition is "bigger loan, higher rate," but it isn't always so. Banks court affluent borrowers and sometimes price jumbos below conforming to win the relationship and the deposits that come with it. What's reliably true is that jumbos ask more of the file: bigger down payments, higher credit scores, and more months of reserves. Because there's no agency rulebook, terms vary widely from lender to lender — shopping matters even more than usual.
The tier in between
In expensive counties, high-balance conforming loans sit between the two: they're still agency-eligible (so easier to qualify than a jumbo) but price a touch above standard conforming. Which bucket you fall into depends on your loan amount and your county's limit — run your numbers on the calculator, and check your metro on rates by city.
