How Jumbo Loans Differ From Conforming Mortgages
Conforming and jumbo loans are underwritten differently because of who ultimately buys or holds the debt.
- Loan limits: Conforming loans must stay below the FHFA cap; jumbo loans exceed it.
- Risk backing: Conforming loans are eligible for purchase by Fannie Mae or Freddie Mac, while jumbo loans are not, so lenders retain more risk directly.
- Qualification standards: Jumbo loans generally call for higher credit scores and larger financial reserves than conforming products.
| Feature | Conforming Loan | Jumbo Loan |
| 2025 Baseline Limit | $806,500 | Above $806,500 |
| Backed by Fannie/Freddie | Yes | No |
| Typical Down Payment | 3 to 5 percent | 10 to 20 percent |
| Credit Score Expectations | Around 620 minimum | 700 or higher preferred |
These figures come from FHFA’s 2025 conforming loan limit data and industry reporting on jumbo underwriting standards.
Credit, Income, and Reserve Requirements
Because jumbo loans are not backed by government-sponsored enterprises, lenders tend to scrutinize a borrower’s full financial picture more closely than they would for a conforming loan.
- Credit score: Most lenders look for a score of 700 or higher, though some programs allow scores as low as 660.
- Down payment: Jumbo loans commonly require a down payment between 10 and 20 percent, compared with the 3 to 5 percent minimum often available on conforming loans.
- Cash reserves: Lenders frequently want to see several months of mortgage payments held in liquid savings after closing.
- Debt-to-income ratio: Underwriters tend to apply tighter limits on how much existing debt a borrower can carry relative to income.
Buyers researching current benchmarks can review the Consumer Financial Protection Bureau’s mortgage resources for general guidance on how lenders evaluate loan applications and disclosures.
