Frequently Asked Questions
What is a jumbo mortgage in 2026?
A jumbo loan exceeds the conforming limit set by the Federal Housing Finance Agency — $806,500 for most counties in 2026, higher in designated high-cost areas. Jumbo loans are not eligible for purchase by Fannie Mae or Freddie Mac, so lenders hold more risk and often require stronger credit, lower DTI, larger down payments, and higher reserves.
Are jumbo mortgage rates higher?
Jumbo rates are often 0.25% to 0.75% above conforming rates, though spreads vary with credit markets. Enter a base rate plus jumbo premium in this calculator to see payment impact. Well-qualified borrowers with large down payments may secure narrower spreads. Shop multiple lenders — jumbo pricing is less standardized than conforming.
How much down payment does a jumbo loan need?
Many lenders require 10-20% down on jumbo loans; some high-balance programs allow less with excellent credit. A larger down payment reduces monthly payment and may improve rate offers. This calculator accepts any down payment percentage — verify minimums with your lender for your loan amount and property type.
Does jumbo include PMI?
Jumbo loans typically do not use standard PMI but may require private mortgage insurance alternatives or lower LTV instead. This calculator omits PMI and focuses on principal, interest, tax, and insurance. If your lender requires insurance or piggyback structures, adjust inputs or use the standard mortgage calculator for blended scenarios.
Jumbo vs conforming — which should I choose?
If your loan amount fits within conforming limits, conforming loans usually offer lower rates and easier qualification. If the home price requires borrowing above the limit, jumbo is necessary unless you increase down payment or use a piggyback second mortgage. Compare payment and total interest at both rate tiers using this calculator.
