Knowing the jumbo loan limits in California is a necessity for some buyers. Here’s why.
California’s real estate market continues to be one of the most expensive in the nation, with property values soaring in metropolitan areas like Los Angeles, San Francisco, and San Diego. As home prices climb, many prospective buyers find themselves looking at properties that exceed the conforming loan limits established by the Federal Housing Finance Agency (FHFA).
In these situations, jumbo loans become a vital financing option for California homebuyers.
What Is a Jumbo Loan?
A jumbo loan is a mortgage that exceeds the conforming loan limits set by the FHFA. Unlike conventional loans, jumbo loans cannot be purchased by Fannie Mae or Freddie Mac, making them non-conforming loans that are held by private lenders.
Jumbo mortgages are designed for high-value properties and cater to high-net-worth individuals, entrepreneurs, freelancers, and self-employed professionals who need larger loan amounts.
These loans typically come in both adjustable-rate and fixed-rate terms of 15 or 30 years, depending on the lender’s offerings.

One important clarification: conforming loan limits are agency thresholds. They determine whether a Full Doc loan can be sold to Fannie Mae or Freddie Mac, and nothing more. They do not govern Defy Mortgage’s Non-QM products — DSCR, Bank Statement, P&L, and Asset Depletion loans are qualified on their own guidelines and are not capped by the county figures in this table.
Any mortgage loan exceeding these county-specific limits would be classified as a jumbo loan.

Eligibility Requirements for California Jumbo Loans
Due to the higher risk associated with larger loan amounts, jumbo loans have more stringent eligibility requirements than conventional mortgages:
Credit Score Requirements
Most jumbo loan lenders in California require a minimum FICO score of 700. For properties valued at $2,000,000 or above, a credit score of 720 or higher is often recommended to secure the best terms and highest loan amounts.
Down Payment Expectations
While conventional loans may allow down payments as low as 3%, jumbo loans typically require 10-20% down for single-family homes. The exact percentage may be higher for:
- Multi-family units
- Second homes
- Investment properties
- Particularly high loan amounts
Larger down payments reduce the lender’s risk and may help secure better interest rates.
Debt-to-Income Ratio (DTI)
Most jumbo loan lenders cap the debt-to-income ratio at 43%, similar to conventional mortgages. This means your total monthly debt payments (including the new mortgage) should not exceed 43% of your pre-tax monthly income. Keeping your DTI below 35% is ideal for obtaining the most favorable loan terms.
Cash Reserves
Jumbo lenders typically require borrowers to demonstrate liquid assets covering at least 6-12 months of mortgage payments. This reserve requirement ensures you can maintain payments even if your income is temporarily disrupted.
Financial Documentation
Expect to provide extensive documentation, including:
- Asset statements
- Bank statements
- Investment account statements
- Tax returns (2-3 years)
- W-2s or 1099s
- Gift letters (if applicable for down payment funds)

Before applying, ensure you meet all eligibility criteria:
