Jumbo Loan Guide 2024

What Is a Jumbo Loan?

A jumbo loan is any mortgage that exceeds the conforming loan limits set by the Federal Housing Finance Agency (FHFA). For 2024, that limit is $766,550 for single-family homes in most U.S. counties (up to $1,149,825 in high-cost areas). Loans above these limits are called jumbo or non-conforming loans because they cannot be purchased by Fannie Mae or Freddie Mac.

Because jumbo loans can't be sold to the GSEs, lenders hold them on their own balance sheets (or sell to private investors). This increases the lender's risk, which is why jumbo loans come with stricter qualification requirements and sometimes higher interest rates than conforming loans.

Jumbo Loan Requirements

Credit Score

Most jumbo lenders require a minimum 700–720 credit score, with the best rates reserved for borrowers with 740–780+. Some lenders require 760+ for the largest loan amounts. The higher the loan amount, the more strictly lenders scrutinize creditworthiness.

Down Payment

Typical jumbo down payment requirements:

• 10% — Available from select portfolio lenders, often with higher rates or stricter reserves
• 15–20% — Standard for most jumbo programs; PMI typically required below 20%
• 20% — Most common requirement; eliminates PMI and gets best rates
• 25–30% — Required by some lenders for very large loans ($2M+)

Debt-to-Income Ratio

Jumbo lenders are stricter on DTI than conforming loan guidelines. Most cap back-end DTI at 38–43%, compared to 45–50% for conventional conforming loans. Some lenders go as low as 36%. If your debt load is high, this can be a significant hurdle for jumbo qualification.

Cash Reserves

A key differentiator from conforming loans: jumbo lenders typically require 6–24 months of PITI (principal, interest, taxes, insurance) payments in liquid reserves. On a $1.5M loan with a $7,000/month payment, that could mean $42,000–$84,000 in documented reserves beyond your down payment and closing costs.

Income Documentation

Jumbo underwriting goes deeper than conforming loans. Self-employed borrowers face extra scrutiny. Expect full tax returns (2 years), business returns, W-2s, pay stubs, and bank statements. Some lenders offer "bank statement" jumbo programs that qualify self-employed borrowers on 12–24 months of bank deposits rather than tax returns.

Jumbo Rates vs Conforming Rates

Historically, jumbo rates ran 0.25–0.75% higher than conforming rates. However, the spread between jumbo and conforming rates has narrowed significantly in recent years, and jumbo rates sometimes temporarily dip below conforming rates when private investor demand for jumbo securities is high.
