In San Diego County, a mortgage becomes a jumbo loan once it goes above $1,104,000 on a one-unit home. That is the 2026 high-balance conforming limit, according to Community First Mortgage's county breakdown. The limit applies to the loan amount, not the price. A $1.4 million home with a large enough down payment can still be financed with a conforming loan.
This guide explains where the line sits, what changes when you cross it, and how to plan around it whether you are buying or selling.
TL;DR
- The 2026 one-unit limit in San Diego County is $1,104,000. The "low-balance" baseline is $832,750.
- Loans between $832,750 and $1,104,000 are high-balance conforming loans. Above $1,104,000 is jumbo territory.
- Jumbo loans can bring stricter requirements, such as reserve funds and lower maximum debt-to-income ratios.
- Veterans with full VA entitlement face no county loan limit for a no-down-payment VA loan, though they must still qualify.
- Sellers should know the limit, because it shapes which financing your buyers can use at your price.

The 2026 limits for San Diego County
Every year the Federal Housing Finance Agency sets the conforming loan limit, the largest loan Fannie Mae and Freddie Mac may buy. FHFA explains that loans above this amount are known as jumbo loans. The limit is higher in expensive counties, and San Diego County is one of them.
For 2026, the national baseline for a one-unit home is $832,750. Fannie Mae's lender letter confirms that figure, a 3.26% increase over 2025. San Diego County sits above the baseline because of its home prices. Its high-balance limit is $1,104,000, as reported by Community First Mortgage.
| Loan amount (one-unit home, 2026) | Category |
|---|---|
| Up to $832,750 | Conforming (baseline) |
| $832,751 to $1,104,000 | High-balance conforming |
| Above $1,104,000 | Jumbo |
Two cautions. First, these numbers are for one-unit properties. Duplexes, triplexes and fourplexes have higher limits, so check FHFA's limit lookup before you plan a multi-unit purchase. Second, limits reset every year. FHFA announced the 2026 values on November 25, 2025, and the 2027 figures are not due until later this fall. If your closing could slip into January, ask your lender which year's limit applies to your loan.
Conforming, high-balance and jumbo: what actually changes
The difference is who can buy the loan after it closes. Conforming and high-balance loans can be sold to Fannie Mae and Freddie Mac. Jumbo loans cannot, so the lender sets its own rules and carries more risk.
That shows up in a few places:
- Qualifying. Community First Mortgage notes that jumbo loans can have tougher requirements, including mandatory reserve funds and lower maximum debt-to-income ratios.
- Down payment. High-balance loans often allow a lower down payment than pure jumbo loans, according to the same source. Terms vary by lender, so get written quotes for both.
- Pricing and programs. Each jumbo lender sets its own menu. Local lenders such as SDCCU publish their own jumbo programs, and credit unions, banks and mortgage brokers all price differently.
A useful way to think about it: the $1,104,000 mark is a threshold between two underwriting systems, not a price cap on the house.
Worked examples: price versus loan amount
Buyers often assume that a home over $1.1 million means a jumbo loan. The loan amount is what counts.
| Purchase price | Down payment | Loan amount | Category |
|---|---|---|---|
| $1,200,000 | 20% ($240,000) | $960,000 | High-balance conforming |
| $1,400,000 | 20% ($280,000) | $1,120,000 | Jumbo, by $16,000 |
| $1,400,000 | 25% ($350,000) | $1,050,000 | High-balance conforming |
| $1,800,000 | 20% ($360,000) | $1,440,000 | Jumbo |
The $1.4 million row is the one worth studying. At 20% down, you land $16,000 over the line. Putting down an extra $70,000 (25% total) moves the loan back under it. Whether that is smart depends on the rate difference between the two products, your reserves and what else you could do with that cash. A lender can run both scenarios in an afternoon, and it is worth asking for both.
The same logic applies to a rate buydown. If you are weighing points against a bigger down payment, our guide on recouping points in 5 to 7 years with a San Diego rate buydown walks through the break-even math.
If you are buying: how to plan around the limit
- Get pre-approved on both sides of the line. Ask for a high-balance quote and a jumbo quote at the same price. The comparison tells you what the extra down payment buys.
- Check reserves early. Jumbo lenders may require reserve funds after closing. Know the number before you write an offer, not after.
- Look at your debt-to-income ratio. If jumbo caps are lower than conforming caps, paying down a car loan before applying can matter.
- Keep the loan amount in view when negotiating. A price reduction of a few thousand dollars, or a seller credit, can pull a loan under $1,104,000 in the right situation.
- Ask about assumable loans. In some cases, taking over a seller's existing VA or FHA loan avoids new-loan limits entirely. We cover how to bridge the equity gap to assume a VA or FHA loan in San Diego.
First-time buyers in San Diego rarely hit jumbo territory, but many land in high-balance range. Our first-time home buyer guide for San Diego in 2026 covers the broader steps, and the home buying tips for first-time buyers cover the basics of budgeting.
Veterans: the county limit works differently
This is the part many San Diego buyers miss, and in a city with a large military community it matters. The VA announced that, starting January 1, 2020, borrowers with full entitlement can use the VA home loan benefit with no down payment regardless of the home's cost. The county loan limits were eliminated for these borrowers under the Blue Water Navy Vietnam Veterans Act of 2019.
There are two caveats:
- You still have to qualify. Lenders apply their own credit, income and debt-to-income standards to VA loans.
- Partial entitlement is different. If you still have an active VA loan or have not had your entitlement restored, the county conforming limit comes back into the calculation to determine whether a down payment is needed, per the VA.

If you are selling: why the limit matters to your price
Sellers rarely think about loan limits, but buyers' financing shapes your offers. Community First Mortgage points out that a seller's pool of potential buyers is sensitive to these thresholds.
Here is what that means in practice. Suppose your home is worth around $1.4 million. A buyer putting 20% down needs a $1,120,000 loan, which is jumbo. A buyer putting 25% down is in high-balance territory. Neither is better or worse, but they face different underwriting, and your price point decides how many buyers sit in each group.
Three things we would do as a seller:
- Price with the financing in mind. If your home sits just above a threshold, think about how the buyer's loan lands at typical down payments.
- Expect jumbo appraisal and underwriting scrutiny. A well-documented sale price and clean comps help any loan, and matter more at higher loan sizes.
- Know your buyers' alternatives. Cash buyers, VA buyers with full entitlement and buyers assuming an existing loan are not constrained by the same limit.
Homeowners 55 and older sometimes compare selling with other equity options before they list. Jumbo reverse mortgage options are one example for higher-valued properties, though programs, rules and availability differ by state, so speak with a lender licensed in California. If you do decide to sell, start with an honest number: our home valuation gives you a local price opinion before you plan around any financing threshold.
Our perspective on loan limits
We have worked San Diego for more than two decades, and the limit conversation comes up the same way each time. A buyer sees a price above $1.1 million, assumes jumbo, and either panics or stretches. The better move is to slow down and ask what the actual loan amount will be.
We do not set rates or approve loans, and we are not lenders. What we can do is make sure you walk into a lender's office with the right questions: what is the loan at 20% down, what is it at 25%, what are the reserves, and how does the monthly payment compare? Then we write offers that fit the financing you chose, and we price listings with the likely buyer's loan in mind.
The other thing we tell clients: the limit is a planning tool, not a verdict. A home a little over the line is not a bad deal, and a home under it is not automatically a good one. The right choice is the one that fits your cash, your timeline and the neighborhood you want.

Checklist before you make an offer
- Confirm the current county limit with your lender, and ask whether your closing date affects which year's limit applies.
- Get two quotes at the same price: one near the high-balance limit, one jumbo.
- Ask each lender for reserve requirements and maximum debt-to-income in writing.
- If you are a veteran, confirm your entitlement type (full or partial) before you shop.
- Decide in advance how much extra cash you would put down to stay under $1,104,000, and what you would rather keep in the bank.
- Pick a property type with the right unit count in mind, since multi-unit limits differ.
FAQ
What is the jumbo loan limit in San Diego County in 2026?
For a one-unit home, a loan above $1,104,000 is jumbo. Loans between $832,750 and that figure are high-balance conforming, per Community First Mortgage. Limits for two to four units are higher, so confirm them with your lender.
Is the conforming loan limit the same as the jumbo threshold?
In San Diego, the relevant conforming limit is the high-balance figure of $1,104,000, and the jumbo threshold starts just above it. The $832,750 baseline is the national number, which Fannie Mae confirmed for 2026. Loans between the two figures still count as conforming.
Can I buy a $1.5 million home without a jumbo loan?
Only if the loan stays at or below $1,104,000, which means putting down roughly $396,000 or more. Otherwise you would need jumbo financing, a VA loan with full entitlement, cash, or an assumable loan. A lender can model each version for you.
Do VA loans have a limit in San Diego?
Not for veterans with full entitlement, who can get a no-down-payment VA loan at any price, as the VA explains. Lenders still apply credit and income standards. Veterans with partial entitlement should ask about how the county limit affects their down payment.
Will the limit change next year?
Probably, because FHFA resets it annually. The 2026 values were announced in late November 2025, so expect the 2027 numbers around the same time. Until then, plan with the 2026 figures.
