California is the largest jumbo loan market in the United States, and it's not even close. When the median home price in cities like Palo Alto exceeds $3.5 million, San Francisco tops $1.35 million, and even suburban communities like Pleasanton and Dublin approach $1.5 million, jumbo loans are simply how most California homebuyers finance their purchases.
What Makes a Loan "Jumbo"?
Any mortgage exceeding the conforming loan limit set by the Federal Housing Finance Agency is classified as jumbo. For 2025, that limit is $1,209,750 for single-family homes in California's high-cost counties — which includes essentially every major metro area in the state.
Multi-unit property limits are higher: $1,548,975 for duplexes, $1,872,225 for triplexes, and $2,326,875 for four-unit properties.
This means a buyer purchasing a $1,400,000 home with 20% down needs a $1,120,000 mortgage — which fits within the conforming limit. But a buyer putting 10% down on the same home needs a $1,260,000 mortgage — that's jumbo territory.
Requirements and Qualification
Jumbo loans have stricter requirements than conforming loans because lenders keep these loans on their own books (or sell them to private investors) rather than selling them to Fannie Mae or Freddie Mac. This means each lender sets their own guidelines.
Most jumbo lenders require credit scores of 700 or higher, with the best rates at 740 and above. Down payments range from 10% to 20% — some lenders offer 10% down jumbo programs with no PMI for strong borrowers. Cash reserves of 6 to 12 months of the total housing payment must remain after closing. DTI ratios are typically capped at 43%, and income documentation must be thorough and verifiable.
Jumbo Rates — Better Than You Think
One of the biggest misconceptions about jumbo loans is that they always carry higher rates. In practice, jumbo rates for well-qualified borrowers often match or beat conforming rates in California.
Why? Banks compete aggressively for high-value clients. A borrower purchasing a $2 million home likely has high income, significant assets, and other banking needs. Lenders offer competitive jumbo rates as a relationship-building tool, hoping to also capture your deposits, investments, and other financial business.
The key is shopping multiple lenders. Jumbo rate variation between lenders is much wider than conforming rate variation — on any given day, the difference between the best and worst jumbo rate you'd be offered might be 0.50% or more. Working with a broker who accesses multiple wholesale jumbo lenders gives you a significant advantage.
Jumbo Loan Strategies for California Buyers
Piggyback loans split the financing into a conforming first mortgage and a smaller second mortgage (HELOC or home equity loan). For example, on a $1,600,000 purchase with 20% down, you could take a $1,209,750 conforming first at the lower conforming rate and a $70,250 HELOC for the remainder. The blended rate may be lower than a single jumbo loan, depending on market conditions.
Asset-based qualification helps borrowers with significant liquid assets but irregular income (common in California's tech and entertainment industries). Some jumbo lenders allow asset depletion — dividing liquid assets by the loan term to create a qualifying income stream.
Interest-only options are available on many jumbo products, providing lower initial payments. On a $1,500,000 loan at 7%, the difference between interest-only ($8,750 per month) and fully amortizing ($9,981 per month) is over $1,200 monthly. For borrowers with variable income or those planning to sell within 5 to 10 years, this flexibility is valuable.
California Jumbo Markets
Every coastal California market is essentially a jumbo market. In Southern California, Newport Beach, Beverly Hills, Malibu, Manhattan Beach, and Santa Monica all have median prices well above the conforming limit. In the Bay Area, Palo Alto, Cupertino, San Francisco, and Pleasanton are solidly jumbo territory. Even traditionally more affordable areas like Long Beach, Pasadena, and Walnut Creek are approaching or exceeding the conforming limit.
The practical implication: if you're buying on the California coast, your lender needs jumbo expertise. Not all lenders are created equal in this space — some have limited jumbo options, slow processing, or unfavorable terms. Save Financial works with a deep network of jumbo lenders specifically because California's market demands it.
