What makes a loan a 'jumbo' loan?

Any loan amount above the conforming limit for the county where the property is located is technically a jumbo loan. The 2026 baseline conforming limit is set by FHFA, and high-cost counties have raised caps. Above that ceiling, you're in jumbo territory.

What credit score do I need for a jumbo loan?

Most jumbo lenders want 700 or higher, and the best pricing usually starts at 740. Some portfolio lenders go lower with strong compensating factors (large reserves, low DTI, relationship pricing).

How much down payment is required?

10–20% is typical on a primary residence. Some lenders offer 5% down jumbo for very strong borrowers, while second homes and investment properties usually require 20–30%+.

Do jumbo loans have PMI?

Some jumbo programs require PMI when LTV exceeds 80%, others use a piggyback structure or lender-paid MI. Many full-doc jumbo programs from depository banks simply price the risk into the rate rather than charging separate PMI.

How many months of reserves do jumbo loans require?

6 months of full PITI is a common baseline for primary residences, 12 months for second homes and investment properties. Retirement assets typically count at 60–70% of vested value, and brokerage assets count at face value.

Can I get a jumbo loan if I'm self-employed?

Yes. Full-doc jumbo programs use two years of tax returns plus a YTD P&L. Non-QM jumbo programs offer bank-statement or asset-based qualification for borrowers whose tax returns understate cash flow.

Are jumbo loans assumable?

Most jumbo loans are not assumable — they're typically held in the lender's portfolio or sold to private-label investors who don't allow assumption. Government loans (FHA and VA) are the assumable categories.
