Every mortgage in America is, at bottom, either conforming or jumbo, and which side of that line your loan falls on shapes almost everything about it: the down payment you need, the reserves you must show, who ends up owning the loan, and sometimes the rate. The line is a single dollar figure, reset every year, and it is worth knowing precisely where it sits.
The 2026 limit, and the high-cost exceptions
For 2026, the Federal Housing Finance Agency set the baseline conforming loan limit for a one-unit property at $832,750, up from $806,500 in 2025 — a 3.26% rise tracking national home-price growth.
In designated high-cost areas — much of California, the New York metro, and similar expensive markets — the limit rises above the baseline, up to a ceiling of $1,249,125. The exact figure is set county by county. Alaska, Hawaii, Guam and the U.S. Virgin Islands get a higher baseline again. Always confirm the limit for the specific county you are buying in, because the number that matters is the local one, not the national baseline.
Why the line exists at all
The limit is the maximum loan that Fannie Mae and Freddie Mac — the government-sponsored enterprises that stand behind most U.S. mortgages — are permitted to buy. A loan at or under the limit “conforms” to their rules and can be sold to them, which makes it liquid, standardised, and cheap to fund. A loan over the limit cannot be sold to them, so the lender must either keep it or sell it to private investors — a smaller, pickier market. That single fact is the source of every difference that follows.
What changes the moment you cross into jumbo
A jumbo loan is not a conforming loan with a bigger number. Because it cannot lean on the GSEs, it is underwritten more conservatively, and the requirements step up:
- Larger down payment. Where conforming loans go down to 3–5%, jumbos commonly want 10–20%, and the best terms often require 20% or more.
- Higher credit bar. Jumbo lenders typically want stronger scores than the conforming minimum — frequently 700 and up, sometimes 740+ for the best pricing.
- Cash reserves. This is the one that surprises people: jumbo lenders often require you to have several months — sometimes six to twelve — of full mortgage payments sitting in reserve after closing, proven in your accounts.
- Tighter debt-to-income and more documentation. The whole file is scrutinised harder, because no standardised agency is buying the risk.
None of this makes a jumbo loan bad — above the limit it is simply the tool for the job. But it means a buyer near the line should know exactly where it is, because nudging just over it can trigger all of the above at once.
Where the cliff falls on a real purchase
The limit applies to the loan amount, not the purchase price — so your down payment determines which side of the line you land on.

That $1,050,000 buyer is over the line by $7,250 — and for that trivial margin faces the entire jumbo rulebook: bigger reserves, higher credit bar, stricter file. It is precisely the situation where a small adjustment is worth considering.
Staying under the line: the piggyback
The classic way to avoid tipping into jumbo is the piggyback — splitting the borrowing into a conforming first mortgage and a smaller second loan, so the first stays at or under the limit.
The structure is often written as 80/10/10 or similar: a first mortgage, a second, and a down payment. It can also be used to avoid PMI on a conforming purchase by keeping the first mortgage at 80% of value. The cost is a second loan, usually at a higher rate and often adjustable, so weigh the second-lien terms against what the jumbo would have demanded. A piggyback trades jumbo's reserve-and-credit requirements for the interest and complexity of a second loan.
Do jumbos really cost more?
The old assumption was that jumbo loans always carry higher rates. That is no longer reliably true. Because jumbo borrowers tend to be affluent and well-qualified — and because banks like holding their loans as a way to win wealthy customers — jumbo rates are sometimes equal to or below conforming rates. It moves with the market and the lender.
So the rate is not the reason to avoid a jumbo. The reasons, where they exist, are the qualification hurdles: the larger down payment and the reserve requirement can be genuine obstacles even for buyers who can comfortably afford the monthly payment. If you are close to the line and short on liquid reserves rather than income, staying conforming may be the difference between approval and denial — not merely a matter of a slightly better rate. Check the affordability calculator to see how the numbers work on your side of the line, and confirm your county's exact limit before you assume which side you are on.
Frequently asked questions
What is the conforming loan limit for 2026?
$832,750 for a one-unit property in most of the United States, up from $806,500 in 2025. In designated high-cost areas the limit rises to a ceiling of $1,249,125, and Alaska, Hawaii, Guam and the U.S. Virgin Islands have a higher baseline of $1,249,125. Confirm the figure for your specific county.
What makes a loan jumbo?
A jumbo loan is one that exceeds the conforming loan limit for its county, so it cannot be bought by Fannie Mae or Freddie Mac. That single fact drives the differences: larger down payments, higher credit requirements, and cash-reserve rules that conforming loans do not impose.
Do jumbo loans have higher interest rates?
Not necessarily anymore. Because jumbo borrowers are typically well-qualified and banks value them as customers, jumbo rates are sometimes equal to or even below conforming rates. The harder part of a jumbo is usually qualifying — the larger down payment and the reserve requirement — not the rate.
How can I avoid a jumbo loan?
A piggyback structure splits the borrowing so the first mortgage stays at or under the conforming limit, with a second loan or HELOC covering the rest — often written as 80/10/10. This avoids jumbo underwriting on the main loan, at the cost of a second lien usually carrying a higher, sometimes adjustable, rate.
Does the loan limit apply to the price or the loan?
The loan amount, not the purchase price. Your down payment determines which side of the line you land on, so a larger down payment can keep an expensive home's loan within the conforming limit. A $1,050,000 home with 20% down produces an $840,000 loan, which is jumbo; a larger down payment could bring it under $832,750.
