- A jumbo loan starts above your county limit: for 2026 that baseline is $832,750 in most of the country and up to $1,249,125 in high-cost counties.
- The bar is higher: expect a credit score around 700 (many lenders want 720+), 10% to 20% down, and 6 to 12 months of cash reserves after closing.
- Jumbo is not always pricier: in several 2026 weeks the average jumbo rate ran below the conforming rate, so shop both before you assume.
- You may be able to avoid jumbo entirely: an 80/10/10 piggyback can keep your first loan under the conforming cap.
- Reserves catch people off guard: the money you need in the bank after closing is the single most common surprise in jumbo underwriting.
What counts as a jumbo loan in 2026
A jumbo loan is simply a mortgage too big for Fannie Mae or Freddie Mac to buy. The dividing line is the conforming loan limit, which the Federal Housing Finance Agency resets every year. The standard calculation that federal law prescribes produced a 2026 baseline loan limit value of $832,750. That is up $26,250 from the 2025 figure of $806,500, a 3.26% bump tied to national home price growth.
Cross that number and you leave the agency world. Because jumbo loans cannot be purchased by Fannie Mae or Freddie Mac, lenders must either hold them in portfolio or securitize them through private channels without a government guarantee, and that higher risk typically translates to stricter qualification requirements. That single fact explains almost everything else about how jumbo underwriting works.
The limit is not one national number. It varies by county, and in expensive metros it is far higher. In high-cost markets where 115% of the local median home value exceeds the national baseline, higher limits apply, and for 2026 the ceiling for one-unit properties in these areas is $1,249,125, which represents 150% of the new baseline. The local limit is higher wherever 115 percent of the local median home value exceeds the baseline, but it cannot be more than 50 percent above the baseline. To find your exact county figure, the Consumer Financial Protection Bureau points buyers to the official lookup; you can check the conforming loan limit for your county before you fall in love with a listing.
A few places get special treatment. Special provisions set different limits for Alaska, Hawaii, Guam, and the U.S. Virgin Islands, where the baseline and ceiling for one-unit homes are $1,249,125 and $1,873,675, respectively. Multi-unit properties also carry their own, larger limits. The full set of county figures comes straight from the FHFA's 2026 conforming loan limit methodology.
Conforming, high-balance, and jumbo: three tiers, not two
Most buyers think in terms of "conforming or jumbo." There is actually a middle tier that matters a lot in pricey counties: the high-balance conforming loan. Fannie Mae's guide describes high-balance loans as those subject to the FHFA high-cost area limits, so in a county where the limit is the $832,750 baseline there is no high-balance band and a larger loan is simply jumbo.
Why care? Because a high-balance loan is still an agency loan. It follows conforming credit and down payment rules, not the tougher portfolio rules a jumbo lender writes. If your loan lands in that band, you keep the easier path. The table below shows how the three tiers compare on the terms buyers feel most.
| Feature | Conforming | High-balance | Jumbo |
|---|---|---|---|
| Loan amount | Up to $832,750 | Above baseline up to county cap ($1,249,125 max) | Above your county cap |
| Backed by GSEs | Yes | Yes | No (lender holds or privately sells) |
| Typical min credit score | 620 | 620 to 680 | 700, often 720+ |
| Typical minimum down | As low as 3% | 5% to 10% | 10% to 20% |
| Reserves after closing | Often ~2 months | A few months | 6 to 12 months |
Before you assume jumbo: if your county is high-cost, a loan between $832,750 and your local cap is high-balance, not jumbo. That can mean a lower down payment and an easier credit bar. Ask your lender which tier your loan actually falls into. For the full menu, see our guide to the types of mortgage loans.

Enter your target price, your planned down payment, and your county's one-unit limit. The tool flags whether your loan would be conforming, high-balance, or jumbo, then estimates the cash you would need up front and in reserve. Use the $832,750 baseline if you are in a standard county, or your county figure (up to $1,249,125) if you are in a high-cost area.

Match with a top local agentJumbo loan credit score requirements
Credit is where jumbo rules bite first. You need a higher credit score to qualify for a jumbo loan than for a conforming loan; one large bank, for example, requires a minimum of 740 for most jumbo loans compared with 620 for a conforming loan. That 620-versus-740 gap is a useful way to picture how much stricter the private market is.
Most lenders land a little lower than that example. Most jumbo lenders require a minimum credit score of 700, and many prefer 720 or higher. Some programs go lower if the rest of your file is strong. While the baseline for conventional loans is generally 620, you will generally need a credit score of 680 or higher to qualify for a jumbo loan. The lower your score, the more the lender wants to see elsewhere, usually a bigger down payment and fatter reserves.
Your debt-to-income ratio matters just as much. Many jumbo programs stay at or below a 43% DTI, which is also the threshold the Consumer Financial Protection Bureau used for the general qualified mortgage standard. If much of your monthly income is eaten up by debt payments, say more than one-third, you might not qualify for a jumbo loan unless your credit score is excellent or you have a sizable amount of reserves or liquid assets. If your score or DTI is borderline, read our breakdown of what credit score you need to buy a house by loan type and consider which debts to pay off first before buying.
Down payment and cash reserves
The down payment myth cuts both ways here. For conforming loans, 20% is optional. For jumbo, it is closer to the real floor. For jumbo loans, lenders typically require a minimum down payment of 10% to 20% of the home purchase price. Go bigger and the loan climbs. For super-jumbo loans of $2 million or more, 25% to 30% down is common.
Low-down-payment jumbo loans exist, but with strings. Unlike conforming loans, jumbo loans do not have a standardized mortgage insurance structure built into their guidelines, and some lenders may require their own private mortgage insurance for lower-down-payment scenarios. If you are weighing how much to put down, our piece on how much down payment a house really needs is worth a read before you drain your savings.
Reserves: the requirement people forget
This is the one that surprises buyers after they have already scraped together the down payment. Be prepared to show enough reserves, or liquid assets, to cover between six and 12 months of mortgage payments. That is on top of your down payment and closing costs, not instead of them. Reserve requirements typically range from 6 to 12 months, and some lenders ask for up to 18 months on loans above $1.5 million.
Put numbers on it. If you are taking out a $1 million jumbo loan, you will likely need $100,000 to $200,000 for a down payment. Add six to 12 months of full housing payments on top, and the cash-to-close picture for jumbo is dramatically larger than most buyers plan for. The calculator above gives you a rough reserve estimate so the number does not blindside you at underwriting.
Reserves are measured as full payments. Lenders count principal, interest, taxes, and insurance (PITI), not just principal and interest. A $7,000 monthly payment at 12 months is $84,000 that has to stay liquid and documented after you close.
Jumbo vs conforming rates: the assumption worth testing
Here is the counterintuitive part. Buyers assume jumbo always means a worse rate. In 2026 that has often been wrong. The Mortgage Bankers Association tracks separate average contract rates for conforming and jumbo balances each week, and the gap between them swings in both directions.
In the MBA survey for the week ending in mid-October 2026, the average contract rate for 30-year fixed mortgages with conforming balances of $832,750 or less was 7.41%, while the average rate for 30-year fixed jumbo balances above $832,750 was 7.33%. In other words, jumbo was the cheaper quote that week. You can read the detail in the MBA weekly mortgage applications survey.
That was not a one-off. Earlier in the year, for the week ending July 17, the average 30-year conforming rate rose to 6.69% while the average 30-year jumbo rate fell to 6.44%, an even wider jumbo discount. But the spread can flip: for the week ending September 11, 2026, MBA put the average 30-year fixed contract rate at 6.97% for conforming loans and 7.03% for jumbo loans. That week, jumbo cost more.
The lesson is not "jumbo is cheaper" or "jumbo is pricier." It is that the jumbo-to-conforming spread moves with lender balance sheets and the private secondary market, so you have to re-shop it every time.

Find an agent who knows jumbo marketsThe 80/10/10 piggyback: staying under the cap
If your loan is only modestly over the conforming limit, you may be able to sidestep jumbo rules entirely. An 80/10/10 piggyback splits your financing: a first mortgage for 80% of the price, a second loan (often a home equity line) for 10%, and 10% down from you. The goal is to keep that first mortgage at or below the conforming limit so it follows the easier agency rules.
Worked example
You are buying a $920,000 home in a standard county where the conforming limit is $832,750. A single loan at 90% would be $828,000, which squeaks under the cap, but at 80% it is only $736,000. Structure it 80/10/10 and your first mortgage ($736,000) is comfortably conforming, a $92,000 second lien covers the gap, and you put $92,000 down. You avoid jumbo underwriting and avoid private mortgage insurance on the first loan.
The tradeoff is a second loan at a higher rate, usually variable, that you will want to pay down or refinance. It is not free money. But when jumbo pricing is unfavorable or the reserve requirements are out of reach, a piggyback can be the difference between qualifying and not. Walk through the full structure, costs, and exit options in our guide to the 80/10/10 piggyback loan. If you are stretching in a pricey metro, also see six ways to buy in a high-cost market.
Red flags and mistakes that sink jumbo approvals
- Budgeting the down payment and forgetting reserves. This is the number one surprise. Map down payment, closing costs, and six to 12 months of payments as three separate buckets.
- Assuming $832,750 is the limit everywhere. In a high-cost county your cap can reach $1,249,125, and a loan in that band may be high-balance conforming, not jumbo.
- Taking one jumbo quote and locking. Jumbo guidelines are set lender by lender, so terms vary widely. Get at least three quotes.
- Letting your DTI creep near 43%. A new car loan or large credit balance can push you over a lender's ceiling right before underwriting.
- Ignoring the piggyback option. If you are barely over the cap, restructuring may be cheaper than jumbo pricing and easier to qualify for.
Steps to qualify for a jumbo loan
Find your county limit
Look up the exact conforming limit for your county. That number, not the national baseline, decides whether your loan is jumbo.
Pull your credit early
Target 700 or higher, ideally 720+. If you are below, a few months of paydown and clean payment history can move you into better pricing.
Document the full cash picture
Down payment, closing costs, and reserves. Keep reserve funds in accessible accounts with a clear paper trail. After accounting for your down payment and closing costs, you also need to show 6 to 12 months of liquid reserves remaining in accessible accounts.
Shop jumbo and conforming structures
Get quotes for a straight jumbo loan and for a conforming-plus-piggyback version. Compare the all-in cost, not just the headline rate.
Get fully pre-approved
Jumbo underwriting is more thorough, so a strong pre-approval carries real weight with sellers. Our guide to getting pre-approved for a mortgage covers the documents lenders actually want.

What is the jumbo loan limit for 2026?
A loan becomes jumbo when it exceeds your county's conforming limit. The 2026 conforming limit for a one-unit home is $832,750 in most of the country and up to $1,249,125 in high-cost counties, and a loan above your county's limit is a jumbo loan.
What credit score do I need for a jumbo loan?
Most jumbo lenders require a minimum credit score of 700, and many prefer 720 or higher. Some programs accept 680 if you offset it with a larger down payment, lower DTI, or stronger reserves.
How much down payment does a jumbo loan require?
For jumbo loans, lenders typically require a minimum down payment of 10% to 20% of the home purchase price. Larger loans require more: for super-jumbo loans of $2 million or more, 25% to 30% down is common.
How much cash do I need in reserves?
Lenders typically want enough liquid assets to cover between six and 12 months of mortgage payments after your down payment and closing costs. Some lenders ask for up to 18 months on loans above $1.5 million.
Are jumbo rates always higher than conforming?
No. The spread moves both ways. In the MBA survey for a mid-October 2026 week, the conforming rate was 7.41% while the jumbo rate was 7.33%, meaning jumbo was cheaper. Other weeks it runs higher, so shop both.
What is a high-balance loan, and is it the same as jumbo?
No. Fannie Mae describes high-balance loans as those subject to the FHFA high-cost area limits. A high-balance loan is still an agency loan with easier rules; a jumbo exceeds your county cap and follows the lender's own stricter guidelines.
Can I avoid a jumbo loan with a piggyback?
Often, yes. An 80/10/10 structure keeps your first mortgage at or below the conforming limit while a second loan covers the gap above your down payment. It can be cheaper and easier to qualify for than jumbo when you are only modestly over the cap.
Why are jumbo loans harder to get?
Because the government does not back them. Lenders take on more risk because they cannot sell jumbo loans to Fannie Mae or Freddie Mac, so jumbo borrowers have to meet stricter requirements for credit, income, and reserves.
The honest bottom line
A jumbo loan is not inherently a bad deal, and it is not automatically more expensive. It is a different set of rules: a higher credit bar, a bigger down payment, and reserves that trip up buyers who only planned for the down payment. The two moves that pay off most are checking which tier your loan actually falls into (conforming, high-balance, or jumbo) and getting real quotes for both a jumbo structure and a conforming-plus-piggyback structure before you commit. Sometimes jumbo wins on rate. Sometimes staying under the cap wins. The only way to know is to run your own numbers, which is exactly what the checker above is for.
