Shopping in La Jolla and wondering if your mortgage will be considered jumbo? You are not alone. Prices along the coast often push loan amounts beyond standard limits, which changes how lenders underwrite and price your loan. In this guide, you will learn what counts as a jumbo loan in San Diego County, how jumbo loans differ from conforming loans, and how to prepare a strong file so you can move forward with confidence. Let’s dive in.
What is a jumbo loan?
A jumbo mortgage is any loan amount that is higher than your county’s conforming loan limit. Conforming loans meet limits set by the Federal Housing Finance Agency (FHFA) and are typically eligible for purchase by Fannie Mae or Freddie Mac. Anything above the county limit is considered non-conforming, or jumbo.
In La Jolla, many homes require jumbo financing because purchase prices often exceed the San Diego County conforming threshold. The exact cutoff changes each year, so you should verify it for the current year.
How to check San Diego limits
To see if your loan will be jumbo:
- Look up the current FHFA conforming loan limit for San Diego County for this year.
- Estimate your loan amount: purchase price minus your down payment.
- If the estimated loan amount is above the county limit, it is a jumbo loan. If it is at or below the limit, it is conforming.
Some lenders also offer “super-conforming” or high-balance products with limits above the baseline but below jumbo. Your lender can tell you which products apply to your price point and property type.
Jumbo vs. conforming: what changes
Rates and pricing
Jumbo rates vary by lender and market conditions. Sometimes jumbo rates are slightly higher than conforming, and other times they are competitive or even a touch lower. It pays to compare quotes from multiple sources, including regional banks, national lenders, and private or portfolio lenders.
Down payment and PMI
- Primary homes: 10 to 20 percent down is common. Many borrowers put 20 percent or more to improve pricing and reduce scrutiny.
- Second homes and investment properties: 20 to 30 percent down is typical.
- Private mortgage insurance: Standard PMI programs are tied to conforming loans. Jumbos often do not use conventional PMI, so you may need a larger down payment or a structured option like lender-paid insurance or a second lien.
Credit, DTI, and reserves
- Credit score: Strong credit is important. Many lenders look for mid to high 700s for best pricing, though some accept high 600s with compensating factors.
- Debt-to-income (DTI): Jumbo loans often cap DTI around 43 to 50 percent. Some portfolio programs allow higher with strong assets and reserves.
- Cash reserves: Expect larger reserves. Six to 12 months of principal, interest, taxes, and insurance is common for primary homes. Second homes or investment properties may require 12 to 24 months.
Documentation you will need
Jumbo underwriting usually requires full documentation. Be ready with:
- Government ID and Social Security or ITIN.
- Two years of federal tax returns. Include business returns if applicable.
- Recent pay stubs and W-2s, or year-to-date profit and loss for self-employed borrowers.
- Two months to two years of bank and investment statements.
- 4506-T authorization so the lender can verify tax transcripts.
- Asset documentation for down payment and reserves. Include gift letters and source of funds if receiving gifts.
- Explanations for large deposits, credit inquiries, or credit events.
Product options
Jumbo products include fixed-rate and ARMs. Some lenders offer interest-only periods, asset-based or asset-depletion options, and bank-statement programs for self-employed or retired buyers. Portfolio lenders can sometimes tailor solutions to complex financial profiles.
La Jolla-specific factors
Appraisals on coastal homes
Luxury and coastal properties often have fewer close comparables and wider price dispersion. Lenders may require a full interior and exterior appraisal, a second valuation review, or even a second appraisal for higher-value or unique homes. Build time into your contract for this step.
Condos and HOAs
Jumbo lenders closely review condo and HOA projects. They will look at budget reserves, insurance coverage, litigation status, and owner-occupancy ratios. Early access to HOA documents helps prevent last-minute delays.
Insurance and risk
Coastal homes may face higher insurance costs. Your lender will require hazard insurance, and flood insurance if the property is in a FEMA flood zone. Earthquake insurance is not typically required by lenders, but it is a real consideration in California and can affect your cash planning.
Property taxes and assessments
San Diego County property taxes, special assessments, and any Mello-Roos in newer developments will factor into your monthly payment and your DTI. Your lender will review the tax records and escrow analysis when qualifying you.
Timing and closing
Jumbo files can take longer to underwrite. Plan for 30 to 45 or more days, especially if your financial picture is complex. In competitive La Jolla scenarios, strong preapproval and coordinated timelines help you write a winning offer.
Foreign nationals and out-of-country buyers
International buyers are active in California coastal markets. Jumbo financing may require larger down payments, extra documentation, and specialized lenders. Start early and expect more verification.
How to prepare a strong file
Before you write an offer
- Speak with a local lender who regularly closes jumbos in San Diego County. Confirm whether your expected loan amount is above the current county limit.
- Get a full preapproval, not just a prequalification. A robust letter helps you compete.
Documentation checklist
- Two years of tax returns and W-2s or K-1s, as applicable.
- Recent pay stubs and year-to-date income documents.
- Bank and investment statements for the last two months or more, depending on lender.
- Proof of down payment and reserves, with source and seasoning of funds.
- Gift letters and verification for any gifted funds.
- Explanations for any non-typical deposits or credit items.
- HOA documents if buying a condo, including insurance and budget.
Strategies for complex income
- Asset-depletion programs can convert investment assets into qualifying income.
- Bank-statement programs can help self-employed buyers whose tax returns do not mirror cash flow.
- Portfolio lenders and private banks can consider your broader financial picture and may offer custom solutions.
Appraisal readiness
Ask your agent to prepare a comp packet with recent, relevant sales in the immediate area. Share it with your lender and the appraiser as early as allowed.
Insurance and title readiness
Request homeowner and, if needed, flood quotes early. For coastal properties, start insurance conversations as soon as you go under contract. Be prepared to address title items such as easements or coastal access.
Reserves and contingencies
Maintain liquid reserves beyond your down payment. If you plan to liquidate securities, start early and document the transfers so underwriting goes smoothly.
