If you’re shopping for a luxury home in San Diego, chances are you’ve already realized one thing—standard mortgages don’t always cut it. That’s where jumbo loans in San Diego come into play.
I’m Trevor Sanders, owner of SD-Loans, and as a San Diego mortgage broker, I specialize in helping buyers like you finance San Diego’s most desirable homes. Let’s talk about what makes a jumbo loan different, how they work, and what you need to know to navigate this part of the luxury real estate world with confidence. Whether you’re eyeing a modern blufftop home in La Jolla or a sprawling coastal estate in Del Mar, I’ve got you covered.
💰 What Is a Jumbo Loan?
A jumbo loan is a mortgage that exceeds the conforming loan limits set by Fannie Mae and Freddie Mac. In 2025, that limit for most of San Diego County is $1,149,825.
So if you’re buying a home priced above that—and not putting down a huge chunk—you’ll likely need a jumbo loan.
📍 Why San Diego Buyers Need Jumbo Loans
The San Diego luxury market is booming. In many top-tier neighborhoods like Rancho Santa Fe, Coronado, or Del Mar, home prices easily climb well past $2M, even $5M+. In those cases, jumbo financing isn’t just an option—it’s the norm.
Common Scenarios Where Jumbo Loans Make Sense
- Buying a primary or secondary residence in a high-end area
- Investing in luxury properties as part of a long-term portfolio
- Relocating executives needing housing that fits their lifestyle
- Self-employed or high-net-worth individuals with complex income

🔍 How Jumbo Loans Differ From Conventional Loans
It’s not just the size that’s different. Jumbo loans have their own rules, and understanding them is key to avoiding surprises.
1. Higher Credit Requirements
Most jumbo lenders look for credit scores of 700 or higher, though exceptions can be made depending on assets and reserves.
2. Larger Down Payments
You’ll typically need at least 10% to 20% down, and in some cases more—especially if the loan amount creeps toward $3M+.
3. Lower Debt-to-Income (DTI) Ratios
Most lenders want to see your DTI under 43%, but a cleaner number around 36% makes for a much smoother approval.
4. More Scrutiny on Assets
Underwriters want to see substantial cash reserves, typically 6–12 months’ worth of mortgage payments in the bank.
🏦 The Jumbo Loan Process—What to Expect
The application process for a jumbo loan is similar to a conventional loan, but it comes with more documentation and tighter verification.
What You’ll Likely Need
- Two years of tax returns
- Recent bank statements
- Proof of reserves
- A detailed breakdown of assets and investments
- Possibly a second appraisal (for ultra-high-value homes)
At SD-Loans, we walk you through all of this step by step. We’re local, we’re experienced, and we know exactly how to package your file to make it shine in front of a lender.

📈 Interest Rates on Jumbo Loans—Are They Higher?
Not always. In fact, jumbo loan rates have become much more competitive in recent years. Sometimes, they’re even lower than conventional rates, depending on the lender and your overall financial profile.
That’s why shopping for the right jumbo loan—with the right broker—can make a huge financial difference.
🔧 How to Strengthen Your Jumbo Loan Application
If you’re preparing to buy in the luxury market, here’s how to put yourself in the best position:
1. Keep Credit Tight
Avoid large purchases, don’t co-sign, and don’t open new accounts in the months leading up to your application.
2. Build Your Reserves
Having 6–12 months of payments in liquid assets shows lenders you’re low risk.
3. Prep Your Financial Paperwork
The cleaner and more organized your file, the faster we get approved. We’ll help you gather and polish every detail.
4. Work With a Local Expert
San Diego’s luxury market moves fast. I know what local lenders want to see, and I know how to make your offer stand out—even before your loan is finalized.
🏡 Jumbo Loans for Second Homes and Investment Properties
Want to buy a vacation home in Mission Beach or an investment duplex in Pacific Beach? Jumbo loans aren’t just for primary residences—they can also finance high-value second homes and rentals.
Just know that guidelines are even more conservative, and down payment minimums will likely be higher.
❓ FAQs
Q1: Can I get a jumbo loan with less than 20% down?
Yes, in some cases—especially with strong credit and income—but expect to pay for private mortgage insurance (PMI) or receive a slightly higher rate.
Q2: Do jumbo loans take longer to close?
Not necessarily. With the right documentation and a proactive broker, you can still close in 30 days or less.
Q3: Can I use a jumbo loan for new construction?
Absolutely. Many of my clients use jumbo financing to build or buy luxury new builds across San Diego.
Q4: Are there jumbo loan programs for self-employed buyers?
