Short answer: A jumbo loan in California is used when the loan amount is above the conforming loan limit for the property area. Approval usually depends on credit, reserves, income documentation, assets, property type, down payment, occupancy, and lender guidelines. High price does not automatically mean hard approval, but jumbo files need clean structure.
2026 conforming loan limits in Southern California
A jumbo loan is used when the loan amount is above the conforming loan limit for the property county. The Federal Housing Finance Agency (FHFA) sets those limits each year. As of November 12, 2026, the official one-unit limits for calendar year 2026 are below. In most of the United States the 2026 baseline one-unit limit is $832,750. The high-cost ceiling is $1,249,125, which is 150 percent of the baseline. Los Angeles County and Orange County are at that ceiling. Riverside County and San Bernardino County use the baseline. A loan above the county one-unit limit is a jumbo loan. In high-cost counties, a loan can still be conforming, often called high-balance, up to the county limit. Figures are from FHFA's Conforming Loan Limits for Calendar Year 2026 official county list, announced November 25, 2025, and confirmed from the official CSV on November 12, 2026. All options are subject to qualification and program guidelines.

FHFA has not announced 2027 conforming loan limits as of November 12, 2026. The agency typically publishes the next year's limits in late November, to take effect on January 1. We will update this table when FHFA posts the official 2027 county list. Until then, do not rely on unofficial estimates.
Who jumbo loans may help
Jumbo loans are common in Southern California because home prices can push borrowers above conforming loan limits. These loans may be used for primary homes, second homes, certain investment properties, purchases, and refinances.
In San Bernardino County, we also review jumbo loans in Rancho Cucamonga, including higher-priced Alta Loma and Etiwanda purchases that sit above the county conforming limit.
What jumbo lenders usually care about
- Credit score and credit depth
- Debt-to-income ratio
- Reserves after closing
- Down payment or equity
- Property type and appraisal
- Income documentation
- Occupancy
- Assets and liquidity
Why structure matters
Jumbo loans are less forgiving than basic conventional files. Reserve requirements, documentation, pricing, and property type can change the outcome. A borrower with strong income can still run into issues if reserves, appraisal, condo review, or income calculation do not fit the guideline.

Self-employed jumbo borrowers
Self-employed jumbo borrowers should review tax-return, bank statement, and non-QM options early. The loan that looks best by rate is not always the one that can actually document the income cleanly.
