Jumbo Loans in San Diego: What You Need to Know in 2026
In San Diego, jumbo loans aren't a niche product for the ultra-wealthy. They're the standard financing tool for a significant portion of the market.
San Diego County's 2026 conforming loan limit is $1,104,000 (FHFA). Any loan above that threshold — on any property type, in any neighborhood — requires jumbo financing. In La Jolla, Del Mar, Carmel Valley, Coronado, Rancho Santa Fe, and much of coastal North County, virtually every single-family purchase is a jumbo transaction.
This guide covers what jumbo loans are, what they require, how rates work in 2026, and why working with a broker who can compare multiple jumbo lenders matters more on a jumbo loan than on any other program.
What Is a Jumbo Loan?
A jumbo loan is any mortgage that exceeds the conforming loan limit set annually by the Federal Housing Finance Agency (FHFA). Conforming loans can be purchased by Fannie Mae and Freddie Mac — jumbo loans cannot. They are held by portfolio lenders or packaged into private-label securities, which means lenders set their own underwriting criteria rather than following Fannie Mae and Freddie Mac guidelines.
In San Diego County, the 2026 conforming limit for a one-unit property is $1,104,000 (FHFA). Any loan above $1,104,000 is a jumbo loan — regardless of property type, neighborhood, or borrower profile.
This has meaningful practical implications:
A conventional loan at $1,000,000 follows Fannie Mae guidelines and can be underwritten by virtually any lender.
A jumbo loan at $1,150,000 follows whichever guidelines the specific portfolio lender has set — and those guidelines vary significantly from lender to lender.
This variation is exactly why jumbo borrowers benefit from working with a broker who can submit the same scenario to multiple jumbo lenders and compare terms.
San Diego Jumbo Loan Requirements in 2026
Jumbo loan requirements are set by individual lenders, not by Fannie Mae or Freddie Mac. The following represents typical program parameters — your specific lender's requirements may differ.
Credit Score:
Most jumbo programs require a minimum credit score of 700 to 720 for standard approval. The best pricing — lowest rates and most favorable terms — generally requires 740 or higher. Borrowers below 700 typically need significantly larger down payments or will not qualify for standard jumbo programs.
Down Payment:
Down payment requirements vary by loan amount and lender:
- 10% down: available on some programs for loan amounts up to approximately $1,500,000, typically requiring 740+ credit and 12 months reserves
- 15% to 20% down: standard for most jumbo programs and loan amounts
- 20%+ down: required for larger loan amounts or borrowers with lower credit scores; eliminates mortgage insurance on most programs
Reserves:
Jumbo lenders require significantly more reserves than conforming programs. Typical requirements:
- 6 to 12 months PITIA for standard jumbo programs
- 12 to 24 months for super jumbo (above $2,500,000)
- Reserves must be liquid or near-liquid — retirement accounts typically count at 60% to 70% of value
Debt-to-Income Ratio:
Most jumbo programs cap DTI at 43%. Some programs allow up to 45% to 49% with strong compensating factors (high credit score, large down payment, significant reserves).
Income Documentation:
Standard jumbo loans require full income documentation — two years of tax returns, W-2s, pay stubs, and year-to-date income verification. Self-employed borrowers with documentation challenges should look at jumbo Non-QM programs — see below.
Jumbo Loan Rates in San Diego in 2026
Jumbo loan rates in San Diego have been trending in the range of 6.4% to 6.9% for 30-year fixed programs (SafeRate, July 2026). Individual rates depend on credit score, loan amount, down payment, reserves, and whether you pay discount points.
One important nuance: jumbo rates are not always higher than conforming rates. Because jumbo borrowers typically have stronger credit profiles and larger down payments than the average conforming borrower, portfolio lenders sometimes price jumbo loans at or near conforming rates — or even below them on well-qualified scenarios.
The spread between jumbo and conforming rates has historically averaged approximately 0.25% to 0.50% (JVM Lending, March 2026), though this varies with market conditions and by lender.
Because jumbo lenders each set their own rate sheets independently, rate variation across lenders on the same scenario can be significant — sometimes 0.25% to 0.50% or more. On a $1,500,000 loan, a 0.25% rate difference translates to approximately $375/month and over $135,000 over the life of a 30-year loan.
This is why comparison shopping matters more on a jumbo loan than on a conforming loan, where rates cluster more tightly around the same Fannie Mae benchmark. Run your own numbers with our mortgage calculator.
Jumbo Non-QM — For Borrowers Who Can't Document Income Conventionally
San Diego's jumbo market includes a significant population of borrowers who have the assets and cash flow to support a large mortgage but cannot document income through conventional channels — self-employed business owners, tech executives with concentrated stock positions, founders post-liquidity event, real estate investors.
For these borrowers, jumbo Non-QM programs provide jumbo financing above $1,104,000 using alternative documentation:
Bank Statement Jumbo: qualifies on 12 to 24 months of personal or business bank deposits rather than tax returns. Available for loan amounts up to $3,000,000 to $5,000,000+ through select wholesale lenders.
Asset Depletion Jumbo: qualifies based on liquid assets divided over a set number of months — typically 84 — to produce monthly qualifying income. A borrower with $8,000,000 in eligible liquid assets produces approximately $95,238/month in qualifying income — sufficient to support a very large San Diego jumbo mortgage with strong credit and reserves.
Jumbo Non-QM rates carry a premium above standard jumbo rates — typically 0.5% to 1.0% — reflecting the alternative documentation structure. For borrowers who cannot qualify conventionally, it is typically the only path to jumbo financing. See also our high-net-worth mortgage options.
VA Jumbo — The Zero-Down Option for Veterans
One of the most powerful and underutilized tools in San Diego's jumbo market is the VA loan for eligible veterans and active duty service members.
Since January 1, 2020, full-entitlement VA borrowers face no county loan limit. An eligible San Diego veteran can purchase a $2,500,000 home in La Jolla, Coronado, or Rancho Santa Fe with zero down payment and no PMI — regardless of the loan amount.
On a $2,000,000 San Diego jumbo purchase:
- Conventional 20% down: $400,000 out of pocket at closing
- VA with full entitlement: $0 down
- VA funding fee (first use): $43,000 (2.15%) — financeable into the loan
- PMI: $0
Source: VA.gov / 38 CFR Part 36
Veterans with a service-connected disability rating of 10% or higher are exempt from the VA funding fee entirely.
Cascada Mortgage Advisors, Inc. arranges VA jumbo loans through multiple wholesale lenders for eligible veterans throughout San Diego County.
Why Brokers Outperform Banks on Jumbo Loans
Jumbo loans are where the broker model creates the most value.
A retail bank offers its own jumbo program — one set of rates, one set of underwriting guidelines, one set of reserve requirements. If your scenario doesn't fit their box, you're declined.
A mortgage broker submits your scenario to multiple jumbo portfolio lenders simultaneously and returns the best combination of rate, down payment requirement, reserve requirement, and underwriting flexibility for your specific situation.
On a $1,500,000 San Diego jumbo loan, finding a rate 0.25% lower than the first lender quoted saves approximately $375/month — or $4,500/year. Over a 10-year holding period, that's $45,000 in interest saved by submitting to multiple lenders instead of one.
Cascada Mortgage Advisors, Inc. (NMLS #2470941, CA DRE #02206556) arranges standard jumbo, jumbo Non-QM, and VA jumbo loans through 100+ wholesale lenders — not as a direct lender.
