What is a jumbo loan?

What makes a loan "jumbo"?

Fannie Mae and Freddie Mac buy most U.S. mortgages from lenders. Each year their regulator, the Federal Housing Finance Agency (FHFA), sets the maximum loan size they can buy. Loans at or under that size are called conforming.

A loan above the limit for your county is a jumbo loan. Fannie Mae and Freddie Mac cannot buy it, so the lender either keeps it or sells it to private investors. That is why jumbo loans follow each lender's or investor's own rules instead of one national standard.

The limit is based on the loan amount, not the home price. A $1.2 million home with a large down payment can still have a conforming loan.

What are the 2026 conforming loan limits?

FHFA announced the 2026 limits on November 25, 2025. They apply to loans acquired starting January 1, 2026.

• Baseline: $832,750 for a one-unit home, up $26,250 from 2025. This applies in most U.S. counties.
• High-cost ceiling: $1,249,125 for a one-unit home, which is 150% of the baseline. Counties with higher home values get a limit between the baseline and this ceiling.
• Alaska, Hawaii, Guam and the U.S. Virgin Islands: the one-unit baseline is $1,249,125, and the ceiling is $1,873,675.

Freddie Mac describes the 2026 increase as 3.26%, based on FHFA's house price index. FHFA said limits rose in all but 32 counties or county equivalents. To find your county's exact figure, use FHFA's conforming loan limit map or ask a loan officer.

What is a high-balance or "conforming jumbo" loan?

In a high-cost county, a loan can be above the $832,750 baseline but still at or below the county's higher limit. The CFPB calls this a "conforming jumbo" loan. Many lenders call it a high-balance loan.

These loans can still be sold to Fannie Mae or Freddie Mac, so they follow agency rules, not jumbo rules. Pricing on them can differ from standard conforming loans, depending on the lender. Only once you go above your county's limit are you in true jumbo territory.

How is jumbo underwriting different?

The CFPB puts it simply: rules vary by lender, but jumbo loans usually need good credit and a high down payment. The items below are typical. Every one of them varies by lender and investor.

• Down payment (varies by lender): many jumbo programs ask for more down than conventional conforming loans, and the required amount often rises as the loan gets larger.
• Credit score (varies by lender): jumbo programs commonly set higher minimum scores than agency loans, and pricing tiers are steeper.
• Cash reserves (varies by lender): expect to show several months of mortgage payments in savings or investments after closing. Larger loans and second homes often need more.
• Documentation (varies by lender): full income documentation is standard. Lenders often ask for two years of tax returns, and self-employed borrowers can expect a deeper review.
• Appraisal (varies by lender): some lenders require a second appraisal on larger loans.
• Debt-to-income ratio (varies by lender): limits are often tighter than on conforming loans.

Because the rules differ, two lenders can give very different answers on the same file. That is one reason borrowers compare jumbo offers from more than one lender.

Do jumbo loans have higher rates?

Not always. Jumbo pricing is set by each lender and its investors, so it can be higher, lower or about the same as conforming rates depending on the market and your profile. The CFPB notes that for non-conforming loans, eligibility, pricing and features can vary widely by lender.

Ask each lender whether it allows a down payment under 20% on a jumbo loan and, if so, whether mortgage insurance or a higher rate applies. Practices vary by lender.

How do you prepare for a jumbo loan application?

Since each lender sets its own jumbo rules, preparation matters more than with an agency loan. A few practical steps:

• Confirm your county's limit first. If your loan would sit only slightly above it, a larger down payment could keep you in conforming territory.
• Gather full documentation early. Pay stubs, W-2s, tax returns, and bank and investment statements are commonly requested. Self-employed borrowers should have business returns ready.
• Know where your reserves are. Lenders look at money left after closing, not just your down payment. Ask how each lender counts retirement and investment accounts, since that varies.
• Avoid new debt before closing. A new car loan or credit line can change your debt-to-income ratio.

Ask each lender for its written program requirements so you can compare them directly.

Are there alternatives to a jumbo loan?

• Put more down to bring the loan under your county's conforming limit.
• FHA: FHA's 2026 one-unit ceiling is also $1,249,125 in the highest-cost areas, but limits are lower in most counties, and FHA has its own mortgage insurance costs.
• VA: eligible borrowers with full entitlement have no VA loan limit, though the lender must still approve the amount.
• Two loans: some buyers pair a conforming first mortgage with a second loan. This adds complexity and a second payment.
