A jumbo loan is a mortgage that's larger than the conforming loan limit — the maximum size Fannie Mae and Freddie Mac are allowed to buy, which federal regulators adjust over time and set higher in expensive housing markets.
Why does that ceiling matter? When a loan conforms, the lender can sell it to Fannie or Freddie and offload the risk. A jumbo loan doesn't qualify, so the lender is holding more risk itself — and it prices and screens accordingly.
In practice, jumbo borrowers face a higher bar:
- Stronger credit scores and lower debt-to-income ratios
- Larger down payments than a typical conforming loan
- Proof of cash reserves, often several months of payments
Jumbo rates can be higher or lower than conforming rates depending on the market, so it's worth comparing rather than assuming. If you're close to the limit in your county, putting more down to squeeze under it can unlock easier qualification. Before you shop at the top of your budget, sanity-check the payment with the mortgage calculator and read up on how much house you can afford.
