Frequently Asked Questions
What is a jumbo loan?
A jumbo loan is a mortgage that exceeds the conforming loan limits set by the FHFA. For 2026, the baseline conforming limit is $832,750 in most U.S. counties, and the high-cost ceiling is $1,249,125 (Alaska, Hawaii, and high-cost metros). Any loan above the applicable county limit is jumbo and cannot be purchased by Fannie Mae or Freddie Mac, which is why jumbo underwriting is stricter and pricing varies more by lender.
How is a jumbo loan payment calculated?
The payment math is identical to any other fixed-rate mortgage: M = P × r × (1+r)^n / ((1+r)^n − 1). A $1,000,000 jumbo loan at 6.5% over 30 years runs roughly $6,320 per month in principal and interest. The calculator returns P&I; jumbo borrowers should also budget for property tax, homeowners insurance, and possibly flood/HOA dues, which on high-value properties can add $1,500 or more per month.
How much down payment do I need on a jumbo loan?
Typical jumbo down payments range from 10% (for very strong borrowers) to 20%–30% (mainstream). Some private banks will go to 5% down for relationship clients, but expect rate premiums and tighter reserve requirements. Above 20% down, you avoid PMI and access the most competitive jumbo pricing — for a $1M home, that's $200,000 down.
Are jumbo loan rates higher than conforming?
Historically jumbos carried a 25–75 basis point premium over conforming because they could not be sold to the GSEs. In 2026 the gap has narrowed and well-qualified borrowers can sometimes get jumbo rates at or below conforming. The reason is that private investors who buy jumbo securities like the credit profile of jumbo borrowers (typically 740+ FICO with significant assets). Shop at least three lenders — jumbo pricing spreads much more than conforming.
What credit score and reserves do I need for a jumbo loan?
Most jumbo lenders want 700+ FICO and 6–12 months of post-closing reserves (cash, retirement, or brokerage balances that could cover principal, interest, taxes, and insurance if your income stopped). Debt-to-income typically caps at 43% but flexibility exists for borrowers with strong reserves. Self-employed borrowers should expect to provide two years of tax returns plus year-to-date P&L.
