Jumbo Loan
A jumbo loan is a mortgage that exceeds the conforming loan limits established by the Federal Housing Finance Agency (FHFA). Because jumbo loans cannot be purchased by Fannie Mae or Freddie Mac, lenders retain more risk and typically impose stricter underwriting requirements.
What This Means
Loan Limits and Classification
A mortgage becomes a jumbo loan when its amount exceeds the conforming loan limit for the property's county. For 2025, the baseline conforming limit is for a single-unit property, with limits reaching in designated high-cost areas. Any loan above the applicable county limit falls into the jumbo category. These thresholds are adjusted annually based on changes in average home prices nationwide.
Underwriting Standards
Jumbo loans carry more stringent qualification requirements than conforming loans. Lenders typically require credit scores of or higher, down payments of or more, and significant cash reserves (often of mortgage payments). Debt-to-income ratio limits are generally tighter, and borrowers may need to document assets more extensively. Because these loans stay on the lender's balance sheet or are sold to private investors rather than the GSEs, each lender sets its own underwriting criteria.
Rate and Cost Considerations
Jumbo loan interest rates were historically higher than conforming rates due to the increased lender risk. However, the spread has narrowed considerably, and jumbo rates are sometimes competitive with or even below conforming rates depending on market conditions and borrower profile. Jumbo borrowers should expect thorough income and asset documentation, and the appraisal process may involve additional scrutiny given the higher property values involved.
