Jumbo Loan Requirements 2026: Credit, Down Payment, and Reserve Standards

A jumbo loan is any mortgage above the conforming loan limit. In 2026, that threshold is $832,750 for a one-unit property in most of the country and $1,249,125 in high-cost areas. Jumbo loans are portfolio products -- lenders hold them on their own books or sell them to specialized investors rather than to Fannie Mae or Freddie Mac. That means each lender sets its own underwriting requirements, and standards vary significantly.

Standard Jumbo Underwriting in 2026

• ✦FICO: 700 minimum at most lenders; best pricing at 740+; some lenders require 720 minimum
• ✦Down payment: 10-20% standard; 10% down available at select lenders but rare above $2M
• ✦DTI: 43% preferred; some lenders approve to 45-50% with strong compensating factors
• ✦Reserves: typically 12 months PITIA in verified liquid assets after closing; some lenders require more on larger loans
• ✦Two years of tax returns for employed borrowers; additional scrutiny on variable income like RSUs and bonuses
• ✦Self-employed: typically requires 24 months of verified self-employment income; stricter than conforming

Lender Differences on Jumbo

Jumbo programs are not standardized the way conforming programs are. JPMorgan Chase requires 680+ FICO and prefers DTI below 43%, with relationship banking discounts available for existing customers. Rocket Mortgage requires 720+ FICO and 20% down for loans above $2M, with dual appraisal required above $2M. UWM's jumbo product runs through their wholesale broker network with specific state limitations. Regional banks and credit unions often have the most competitive jumbo rates but limited geographic footprints.

Super Jumbo: Above $2 Million

Loans above $2M enter super jumbo territory. Underwriting tightens further: dual appraisals are commonly required, reserves may be measured in years rather than months, and income documentation is more extensive. Some lenders have hard stops at $3M or $5M. Griffin Funding, Deephaven, A&D Mortgage AD Power Jumbo, and Verus Mortgage Capital serve the upper end of the jumbo market with products up to $5M.

Jumbo ARMs vs. Fixed

Jumbo borrowers frequently use adjustable-rate mortgages. A 7/6 or 10/6 ARM on a jumbo loan is common for high-income borrowers who plan to pay down or sell within 10 years and want to minimize initial carrying cost on a large balance. The rate spread between jumbo ARMs and 30-year fixed has varied significantly -- in some rate environments the ARM savings are meaningful; in others the fixed rate is close enough that the risk is not worth taking. Always model both for the borrower.
