A jumbo loan is a mortgage that exceeds the conforming loan limit set each year by the Federal Housing Finance Agency. Because these loans are too large to be bought by Fannie Mae and Freddie Mac, lenders carry more risk and apply stricter standards. If you are buying an expensive home, understanding jumbo requirements is essential.
The conforming limit and what crosses it
Each year the FHFA sets a baseline conforming loan limit that rises with home prices; in 2025 the baseline was $806,500, with higher ceilings up to roughly 150% of that in high-cost counties. A loan above the applicable limit for your area is a jumbo loan and cannot be sold to Fannie Mae or Freddie Mac. Lenders either hold jumbo loans on their own books or sell them to private investors. That lack of a government-sponsored buyer is why the underwriting is tougher.
Stricter qualifying standards
Because the lender shoulders more risk, jumbo loans typically demand higher credit scores, often 700 or above, and lower debt-to-income ratios. Down payments are frequently larger, commonly 10% to 20% or more, though some programs allow less for very strong borrowers. Lenders usually require substantial cash reserves, sometimes several months to over a year of payments held in the bank. Expect more documentation of income and assets than a conforming loan requires.
How rates and costs compare
Jumbo rates were historically higher than conforming rates, but they have at times matched or even dipped below conforming rates for the strongest borrowers, since jumbo customers tend to be affluent and low-risk. Appraisal requirements can be more rigorous, and some lenders require two appraisals on very large loans. Closing costs scale with loan size, so the dollar amounts are larger even at similar percentages. Shopping multiple lenders matters even more in the jumbo market because pricing varies widely.
Alternatives to going jumbo
If your loan is only slightly over the limit, a larger down payment can bring it back under the conforming ceiling and simplify approval. Some buyers use a piggyback structure, pairing a conforming first mortgage with a second loan to cover the gap. Buyers in high-cost counties should confirm their local limit, since it may be far above the national baseline and avoid jumbo status entirely. Weigh the extra reserves and stricter terms of a jumbo against these alternatives.
Imagine buying a $1 million home in a county where the conforming limit is $806,500. Financing $850,000 would be a jumbo loan requiring, say, a 720 score, 20% down, and a year of reserves. Putting down $200,000 instead would drop the loan to $800,000, potentially keeping it conforming and easing approval.
Key takeaways
- A jumbo loan exceeds the FHFA conforming limit and cannot be bought by Fannie Mae or Freddie Mac.
- The 2025 baseline conforming limit was $806,500, with higher ceilings in expensive counties.
- Jumbo loans usually require higher credit scores, larger down payments, and bigger cash reserves.
- Jumbo rates can be comparable to or below conforming rates for very strong borrowers.
- A larger down payment or a piggyback second loan can keep you under the conforming limit.
Common mistakes
- Assuming any large loan is automatically jumbo without checking your county's specific limit.
- Underestimating the cash reserves a jumbo lender expects on top of the down payment.
- Skipping rate shopping in the jumbo market, where pricing varies widely between lenders.
FAQ
Are jumbo loan rates always higher?
Not anymore. Jumbo rates sometimes match or fall below conforming rates because jumbo borrowers are typically low-risk, though pricing varies by lender. Always compare offers.
Does the conforming limit vary by location?
Yes. High-cost areas have higher limits, up to roughly 150% of the baseline. Check the FHFA limit for your specific county before assuming a loan is jumbo.
