Jumbo loans: what happens when you borrow above the conforming limit

Where the line sits in 2026

FHFA, which regulates Fannie Mae and Freddie Mac, sets the limits each year. For 2026, the baseline limit for a one-unit home is $832,750. In high-cost areas the limit is higher, up to a ceiling of $1,249,125 for one-unit homes, and special rules apply in Alaska, Hawaii, Guam and the U.S. Virgin Islands. Limits are higher for two- to four-unit properties.

The limit applies to the loan amount, not the price. A $950,000 home can carry a conforming loan if your down payment brings the loan below your county's limit.

How jumbo lending differs

Because Fannie Mae and Freddie Mac do not buy jumbo loans, their guidelines do not apply. Each lender sets its own standards for credit scores, down payments, debt ratios and cash reserves, and those can differ a lot from one lender to the next. Expect closer scrutiny of income and assets, and ask each lender what it needs.

Pricing differs too. The CFPB notes that a jumbo loan may cost more than a conforming one. At times, though, some lenders price jumbo loans competitively, so get quotes rather than assuming.

Consumer protections still apply

Jumbo loans are not a regulatory free-for-all. The CFPB explains that lenders must make a good-faith effort to determine your ability to repay any mortgage. Unlike government-backed loans, jumbo loans must meet special requirements to count as qualified mortgages, which rule out features such as interest-only periods, negative amortization and terms longer than 30 years.

Jumbo loans also have their own threshold for being classed as higher-priced. The CFPB says a first-lien jumbo loan is generally higher-priced if its APR is 2.5 percentage points or more above the average prime offer rate, compared with 1.5 points for other first liens. Higher-priced loans come with added protections such as escrow and appraisal requirements.

Options near the limit

• Put more down. As in Lena's case, a modest increase can keep a loan conforming.
• Negotiate the price. A lower price reduces the loan for the same percentage down.
• Pair a conforming first with a second loan. Some buyers combine a first mortgage at the limit with a second mortgage. The CFPB warns that second mortgages often carry higher rates and add to your total debt, so compare the combined cost.
• Choose a jumbo loan. If reserves matter more, a jumbo loan may be the better trade.

Cash reserves

Jumbo lenders often look closely at the money you will have left after closing. Even if a lender does not require much, keeping reserves protects you from repairs and income disruptions in a more expensive home.

The bottom line

A jumbo loan is any mortgage above your county's conforming limit, which in 2026 starts at $832,750 for one unit. Jumbo loans follow lender rules rather than Fannie Mae and Freddie Mac guidelines, so compare several lenders, and check whether a bit more down could keep you conforming.
