Buying a Home in San Diego County in 2026: A Mortgage Broker's Guide
The short answer
Buying a home in San Diego County in 2026 means planning for prices that sit around or above the $1 million mark for a typical single-family home, a 2026 conforming loan limit of $1,104,000 for a one-unit home, and an insurance and property tax picture that is different from most other states. The buyers who do best get fully pre-approved before they shop, understand which loan category their price range falls into, and budget for the full cost of ownership, not just the price tag.
I'm Peter Seroter, an independent mortgage broker with 25 years in the business. I live in North Phoenix, but I'm licensed in both Arizona and California, and I spend a fair amount of time in San Diego because my brother lives there. Every time I visit, I end up doing the same thing: driving past open houses, checking listing prices on my phone, and doing quick mental math on what it actually takes to buy in this market.
This guide is the conversation I'd have with you over coffee if you told me you wanted to buy a home in San Diego County this year. No sales pitch, just how the market looks, how financing works here, and where buyers tend to get tripped up.
Where San Diego County Home Prices Stand in 2026
San Diego is one of the most expensive housing markets in the country, and 2026 hasn't changed that. The exact "median price" you see depends on who is measuring and what they're counting, so here's what the numbers looked like as of mid-2026:
The California Association of Realtors reported a median price for existing single-family homes in San Diego County of about $1.085 million in June 2026, up roughly 5.9% from a year earlier.
Redfin's June 2026 report, which includes all home types, put the county's median sale price closer to $950,000, up about 3.5% year over year.
Redfin also reported homes selling in a median of about 27 days, with roughly 2.5 months of supply, which is still a seller-leaning market.
Prices also vary a lot by city. Using Redfin's spring 2026 averages, the City of San Diego ran just under $1 million, Chula Vista, Escondido and Oceanside generally landed in the low-to-mid $800,000s, Carlsbad was around $1.5 million, and coastal spots like Encinitas and Coronado ran well above $2 million. In other words, "San Diego County" is really several different markets wearing the same name.
When I'm visiting my brother, I notice how much the home itself changes as you move inland. Closer to the coast you're often paying for location and lot, and the homes can be older and smaller. Head toward North County inland or the East County, and you'll typically find newer construction, bigger floor plans, and more yard for the money, traded against a longer drive to the beach or downtown.
Know Your Loan Category Before You Shop
In a market priced like San Diego, the single most useful thing you can know before touring homes is which loan category your target price range falls into. That affects your documentation, your reserves, and which lenders compete for your file.
Conforming and high-balance loans
Each year the Federal Housing Finance Agency (FHFA) sets the maximum loan amount Fannie Mae and Freddie Mac will buy. For 2026, the national baseline for a one-unit home is $832,750. San Diego County is designated a high-cost area, so its 2026 limit for a one-unit home is $1,104,000. Loans between the baseline and that county limit are often called "high-balance" conforming loans.
For two- to four-unit properties the county limits are higher: about $1,413,350 for two units, $1,708,400 for three units, and $2,123,100 for four units.
Jumbo loans
If your loan amount goes above the county limit, you're in jumbo territory. Jumbo guidelines are set by each lender rather than by Fannie and Freddie, so credit, reserve and documentation requirements can vary quite a bit from one lender to the next. This is exactly where shopping a wide range of lenders matters. I have access to more than 180 wholesale lenders, and jumbo is the category where those differences tend to show up the most.
FHA, VA and other options
Government-backed programs are also available in San Diego County, and there are low down payment options for qualified buyers. Each program has its own limits, property standards and costs, and the right fit depends on your full picture. I'd rather run your real numbers side by side than guess.
First-Time Buyers: Down Payment Help Through CalHFA
The California Housing Finance Agency (CalHFA) is the state's affordable housing lender, and it doesn't lend directly to the public. It works through approved lenders. Its MyHome Assistance Program is a deferred-payment junior loan that can help with down payment and closing costs when it's paired with a qualifying CalHFA first mortgage.
The basics, at a high level:
It's designed for first-time homebuyers who will live in the home as their primary residence.
Borrowers must fall within CalHFA's income limits for the program.
Homebuyer education is required, completed through an approved provider.
Eligible properties include single-family homes and approved condos, among others.
Program details change, and funding and guidelines get updated, so always confirm the current terms with a CalHFA-approved lender before you count on assistance in your plan.
Budget for the Full Cost of Owning
This is the part I see buyers underestimate most, especially people coming from out of state. The purchase price is only the starting point.
Property taxes and Mello-Roos
Under Proposition 13, California's base property tax rate is 1% of assessed value, and your assessment is generally reset to your purchase price when you buy. On top of that base, many properties carry voter-approved charges and special assessments. One to watch for in San Diego County is Mello-Roos, a special tax that repays bonds used to fund local public improvements like roads, fire protection and libraries. The San Diego County Assessor's office has a lookup process using the parcel number, so you can find out whether a home sits in one of these districts before you write an offer.
Homeowners insurance
California's home insurance market has been tight for several years, with some carriers pulling back and more homeowners turning to the California FAIR Plan, the state's coverage option of last resort. There are signs of improvement in 2026: the state's Sustainable Insurance Strategy allows insurers to use updated rate-setting tools in exchange for commitments to write more policies in higher-risk wildfire areas, several major carriers have said they'll expand in California, and FAIR Plan growth slowed sharply in early 2026. Even so, my advice is to get an insurance quote on a specific property early in your escrow, not at the end. Lenders need proof of coverage to close, and depending on location, wildfire exposure can change your options.
HOA dues
Condos, townhomes and many newer planned communities in San Diego County come with HOA dues. Those dues count in your debt-to-income calculation the same way your housing payment does, so get the HOA figure early and factor it in when comparing homes.
How I Help California Buyers From Arizona
People sometimes ask why a broker based in North Phoenix is talking about San Diego. Fair question. I'm licensed in California as well as Arizona, and mortgage work today is mostly digital: documents, disclosures and e-signatures move the same way whether you're in Mission Valley or Moon Valley. What doesn't change is how I work. I personally handle every file from start to finish, so you're not handed off to a call center after your first conversation. I lived in Southern California for 10 years and have family still in San Diego, so I have many contacts from real estate agents to other home owner related services.
And when I'm out visiting, I'm usually the guy pulling up listings at dinner and talking through what a given price range really buys. I know San Diego as someone who keeps coming back, and I know California lending as someone who does it for a living.
A Simple Game Plan for San Diego Buyers
Get fully pre-approved, not just pre-qualified. In a market with homes selling in under a month, sellers want to see that your income, assets and credit have been reviewed.
Find your loan category. Know whether your target price range lands you in conforming, high-balance or jumbo, and plan your reserves accordingly.
Check for assistance early. If you're a first-time buyer, ask about CalHFA programs before you set your budget.
Get insurance quotes on real addresses. Do it as soon as you're seriously considering a home.
Look up Mello-Roos and HOA costs. These can change your budget more than a small difference in purchase price.
Run your real numbers. Generic online calculators can't account for your taxes, insurance, HOA and loan type. Let's run them together.
