What Is a Jumbo Loan? Requirements, Rates, and How They Work
February 23, 2026
You've found the right home, but it's priced at $950,000. With 10% down, you need a $855,000 mortgage. Your lender explains that this exceeds the conforming loan limit, so you'll need a jumbo loan. Suddenly, the rules change.
A jumbo loan is a mortgage that exceeds the conforming loan limit, meaning it can't be backed by Fannie Mae or Freddie Mac. Because the lender takes on more risk by keeping these loans in their own portfolio, the qualification standards are higher and the rates are typically less favorable than conforming loans.

When You Need a Jumbo Loan
For 2026, the conforming loan limit is $806,500 in most of the United States and up to $1,209,750 in designated high-cost areas. Any mortgage above your area's limit is a jumbo loan.
Here's when borrowers typically encounter jumbo territory:
- Buying a home priced above $1 million with a standard down payment
- Purchasing in an expensive market where even average homes exceed the limit
- Buying a second home or investment property with a larger loan amount
- Refinancing an existing jumbo loan
In some high-cost markets like San Francisco, New York City, or Honolulu, the elevated conforming limit means you can borrow up to $1,209,750 before entering jumbo territory. Check your county's specific limit before assuming you need a jumbo loan.
Jumbo vs. Conforming Loans
The key differences come down to risk. Without Fannie Mae and Freddie Mac backing, lenders set their own guidelines for jumbo loans, and those guidelines are almost always stricter. For a deeper look at how these two loan types compare, see our jumbo vs conforming loan guide.
| Conforming Loan | Jumbo Loan | |
|---|---|---|
| Maximum loan amount | $806,500 (standard) | No hard limit |
| Minimum credit score | 620 | 700-720 (sometimes higher) |
| Maximum DTI | 45-50% | 38-43% |
| Minimum down payment | 3-5% | 10-20% |
| Cash reserves required | 0-2 months | 6-12 months |
| Interest rate | Lower | Higher by 0.25-0.5% |
| PMI availability | Standard | Varies by lender |
These are general ranges. Individual lenders set their own jumbo criteria, so requirements can vary significantly. Some lenders specialize in jumbo lending and offer more competitive terms.

Jumbo Loan Requirements
Credit Score
Most jumbo lenders require a minimum credit score of 700, with many preferring 720 or higher. A score of 740+ will get you the best jumbo rates.
Compare this to conforming loans, where the minimum is 620. Lenders want more confidence in your creditworthiness when the loan amount is larger, because the potential loss from a default is greater.
Down Payment
Expect to put down 10% to 20% on a jumbo loan. Some lenders offer jumbo loans with as little as 10% down, but 20% is more common, especially for loan amounts well above the conforming limit.
On a $1 million home:
- 10% down = $100,000
- 15% down = $150,000
- 20% down = $200,000
That's a significant amount of cash, which is why jumbo borrowers tend to have higher incomes and more substantial savings.
Income and Asset Documentation
Jumbo underwriting requires extensive documentation:
- Two years of tax returns (both personal and business, if self-employed)
- Recent pay stubs and W-2s
- 2 to 3 months of bank and investment account statements
- Proof of cash reserves (6 to 12 months of mortgage payments in liquid assets)
The reserves requirement is particularly important. Lenders want assurance that if something goes wrong (job loss, medical emergency), you can keep making payments for months while you figure things out.
Debt-to-Income Ratio
Jumbo lenders typically cap your DTI at 38% to 43%, lower than the 45% to 50% sometimes allowed for conforming loans. With larger loan amounts, lenders want a bigger buffer between your monthly obligations and your income.
Second Appraisal
Some jumbo lenders require two independent appraisals instead of one. With more money on the line, they want extra assurance that the property is worth what you're paying. This adds $400 to $700 in costs and some time to the process.
Jumbo Loan Interest Rates
Historically, jumbo loan rates were significantly higher than conforming rates. That gap has narrowed considerably in recent years, and sometimes jumbo rates have even dipped below conforming rates.
As of early 2026, the typical spread is:
- Conforming 30-year fixed: around 6.0% to 6.5%
- Jumbo 30-year fixed: around 6.25% to 6.75%
That 0.25% to 0.50% premium may seem small, but on larger loan amounts, the dollar impact is significant:
| Loan Amount | Rate | Monthly Payment |
|---|---|---|
| $900,000 (conforming in high-cost area) | 6.25% | $5,541 |
| $900,000 (jumbo) | 6.50% | $5,688 |
| Difference | 0.25% | $147/month ($52,920 over 30 years) |
That's nearly $53,000 more in interest over the life of the loan, just from the rate premium. This is why borrowers near the conforming limit often look for ways to keep their first mortgage within conforming territory.
Strategies to Avoid a Jumbo Loan
If your mortgage amount is close to the conforming limit, there are several approaches to consider:
Increase Your Down Payment
The most straightforward approach. If the home costs $900,000 and the limit is $806,500, putting down $93,500 (about 10.4%) instead of the minimum keeps you in conforming territory.
Piggyback Loan Structure
Use two loans: a conforming first mortgage at or below the limit, plus a smaller second mortgage (typically a home equity line of credit) for the rest. For example:
- First mortgage: $806,500 (conforming rate)
- Second mortgage: $93,500 (higher rate, but small balance)
- Down payment: the remainder
The blended rate might still be lower than a single jumbo loan, depending on current pricing.
Choose a High-Cost Area Lender
If you're buying in a designated high-cost area, make sure your lender is using the correct, higher conforming limit for your county. Some online lenders default to the standard limit when a higher one applies.
Jumbo Loan Options
Jumbo loans come in the same flavors as conforming loans:
Fixed-rate jumbos: The most popular choice. Your rate stays the same for 15 or 30 years. Predictable payments make budgeting straightforward.
Adjustable-rate jumbos (ARMs): These start with a lower rate that adjusts after an initial fixed period (typically 5, 7, or 10 years). Jumbo ARMs are more common than conforming ARMs because the rate savings on a larger loan amount can be substantial. A 7/1 ARM on a $900,000 loan might save $200 to $300/month compared to a fixed rate during the initial period.
Interest-only jumbos: Some lenders offer interest-only periods (typically 5 to 10 years) on jumbo loans. During this time, your payment covers only interest, and the principal balance doesn't decrease. This lowers your initial payments but means you're not building equity through amortization. These are most common among high-income borrowers who want cash flow flexibility.
Jumbo Loan Refinancing
Refinancing a jumbo loan works the same way as refinancing any other mortgage, but with the same stricter qualification requirements. You'll need the higher credit score, lower DTI, and larger reserves.
One potential benefit: if your home has appreciated and the conforming loan limit has increased, you might be able to refinance into a conforming loan. For example, if you originally borrowed $830,000 (jumbo) and have paid it down to $790,000, and the conforming limit is now $806,500, you could refinance into a conforming loan at a lower rate.
Shopping for a Jumbo Loan
Because jumbo loans aren't standardized by Fannie Mae or Freddie Mac, rates and terms vary more from lender to lender. Shopping around is especially important.
Get at least three quotes. The spread between the best and worst jumbo offer can be 0.5% or more, which translates to hundreds of dollars per month.
Consider different lender types. Large banks, credit unions, and specialty lenders all offer jumbo loans with different strengths. Credit unions sometimes offer the most competitive jumbo rates because they keep loans in their own portfolios.
Compare the APR, not just the rate. Jumbo loans can have higher origination fees and closing costs. The APR gives you the true cost comparison.
Negotiate. With larger loan amounts, lenders are often more willing to negotiate on rates and fees. You represent more revenue to them, so use that as leverage.
Shop Harder Than You Would for a Conforming Loan
Jumbo loans make it possible to finance homes that exceed the conforming loan limit. The tradeoff is higher rates, stricter qualification standards, and larger down payment requirements. If you're buying in the $800,000+ range, understanding the jumbo threshold for your area helps you plan your down payment and financing strategy.
Where possible, structuring your financing to keep the first mortgage within conforming limits saves money over the long run. But if a jumbo loan is your best option, shop aggressively across multiple lenders. The lack of standardization in the jumbo market means there are bigger differences between lenders, which works in your favor as a savvy borrower.
