10 Things Every Buyer Should Know Before Buying a Home in San Diego
San Diego is one of the most competitive and most expensive housing markets in the country. That combination is what makes it so easy to lose money here before you ever write an offer — not because buyers are careless, but because most of the advice floating around online was written for a market that looks nothing like ours.
I put together a video walking through the ten things I want every buyer to understand before they start shopping in San Diego. Here's the written version.

1. You do not need 20% down
This is the single biggest myth that keeps people renting longer than they need to.
Twenty percent down avoids mortgage insurance, and it does help your monthly payment. But it is not a requirement. Conventional loans can go as low as 3% down. FHA is 3.5%. VA loans, which matter a lot in a military town like ours, can be zero down. There are also down payment assistance programs specific to California and San Diego County that a good lender will walk you through.
Loan limits matter here too. For 2026, San Diego County's high-balance conforming limit is $1,104,000, with a baseline conforming limit of $832,750. Staying under those thresholds usually means a better rate and easier underwriting, so it's worth knowing where your price point falls before you fall in love with a house.
The real question isn't "do I have 20%?" It's "what can I put down, what does that do to my payment, and how fast do I get back to a comfortable cash reserve after closing?"
2. The monthly payment matters more than the purchase price
Buyers anchor on price. Lenders and sellers care about payment.
A $950,000 home and a $1,000,000 home can end up closer in monthly cost than you'd think depending on rate, down payment, property tax rate, insurance, and HOA. And two homes at the exact same price can have wildly different payments — one in a Mello-Roos district with a $400 HOA, one in an older neighborhood with neither.
Before you tour anything, ask your lender for a full payment breakdown at a few different price points: principal, interest, property taxes, insurance, mortgage insurance if it applies, HOA, and any special assessments. That number is your actual budget. The list price is just the headline.
3. Interest rates change everything
Rates move your buying power more than almost anything else you control.
As of late July 2026, the 30-year fixed averaged about 6.66% nationally. A one-point swing in rate can change your payment by hundreds of dollars a month on a San Diego-priced home, which in turn changes the price range you qualify for.
Two things follow from that. First, get re-quoted if your search runs long — a pre-approval from four months ago may not reflect what you can actually afford today. Second, don't wait for a perfect rate. If rates drop meaningfully, you refinance. If they drop and you're still renting, you're now competing with every other buyer who was also waiting, in a market with limited inventory. Falling rates in San Diego historically bring more competition, not better deals.
4. Pre-approval is not optional here
In a lot of markets you can look first and get pre-approved later. Not in San Diego.
Listing agents here will not take an offer seriously without a strong pre-approval attached, and in multiple-offer situations a shaky letter is the fastest way to get skipped. There's also a real difference between a pre-qualification (a quick conversation) and a pre-approval (documented income, assets, and credit that an underwriter has actually reviewed). Ask your lender which one you're getting.
The other reason to do it early: pre-approval is where you find the problems. Credit issues, gaps in employment history, a large deposit you can't source, self-employment income that has to be averaged a certain way — all of that is fixable if you find it in month one and painful if you find it in escrow.
5. Closing costs catch people off guard
Down payment is not the only cash you need. Plan on roughly 2% to 5% of the loan amount in closing costs, and understand what's inside that number:
- Lender fees, origination, and any points you buy
- Appraisal and credit report
- Escrow and title fees
- Prepaid property taxes and homeowners insurance
- Prorated interest for your first partial month
- HOA transfer fees and document fees, which can run several hundred dollars in San Diego
- Home inspection, plus any specialty inspections — sewer, roof, termite, foundation
Some of these are negotiable and some can be credited by the seller depending on the market and how the offer is structured. That's a conversation to have before you write, not after.
6. Location matters more than the house
You can renovate a kitchen. You cannot move a house closer to the coast, into a different school boundary, or off a busy street.
San Diego is a collection of very different micro-markets, and they don't move in lockstep. Carmel Valley, North Park, Chula Vista, Bay Park, La Mesa, Escondido — different price points, different buyer pools, different appreciation patterns, different commutes, and very different day-to-day lifestyles. Marine layer alone changes how a neighborhood feels; a house five miles inland can run ten to fifteen degrees warmer in the afternoon.
My advice is to spend real time in a neighborhood before you commit to it. Drive the commute at the actual hour you'd be driving it. Walk it on a weekend evening. Check flight paths, freeway noise, and street parking. The house is a decision you can revisit with money. The location is not.
7. HOAs can make or break the deal
Plenty of great San Diego properties sit inside an HOA, and plenty of buyers sign the disclosure package without reading it.
Things worth knowing before you remove your contingency:
- What the dues are today and what they've been raised to over the last five years
- Whether reserves are adequately funded, or whether the association is one repair away from a special assessment
- What the master insurance policy covers and what it excludes, since coverage costs across California have moved a lot
- Rental restrictions, if there's any chance you'd lease the place out later
- Pending litigation, which can affect your ability to get financing at all
- Mello-Roos, which is separate from HOA dues and shows up on the tax bill in many newer communities
A $500 monthly HOA is $6,000 a year that isn't building your equity. Sometimes it's absolutely worth it. Just make it a decision instead of a surprise.
8. New builds are not automatically the better choice
New construction is appealing for obvious reasons — nothing to fix, modern layout, warranty coverage, energy efficiency.
But go in with your eyes open. Base price is rarely the price you pay once you're through the design center. Lot premiums, upgrades, and landscaping add up fast, and much of that doesn't come back to you dollar for dollar at resale. Builder timelines slip, which is a real problem if you have a lease ending or a home to sell. Builder incentives are usually tied to using their preferred lender, and that trade-off is worth pricing out. Newer communities in San Diego frequently carry Mello-Roos and HOA dues on top of your mortgage. And the community itself may not be finished for years, which means construction traffic and an unsettled resale picture in the meantime.
Also worth saying clearly: you can and should bring your own agent to a new construction sales office, on your first visit. The person at the desk represents the builder.
9. Stop trying to time the market
Every year I talk to buyers waiting for the crash, the correction, or the perfect rate. Some of them have been waiting since 2019, and the homes they were looking at then cost meaningfully more now.
San Diego has structural constraints most markets don't: limited developable land, the ocean on one side, and persistent demand from employers, the military, and universities. That doesn't guarantee prices only go up — the last two years have shown plenty of month-to-month softness, and some submarkets have flattened or dipped. But it does mean the odds of a deep, sustained discount are lower here than the internet suggests.
The better questions are the ones you can actually answer: Are you planning to stay put for at least five to seven years? Is your income stable? Do you have reserves after closing? If those are yes, timing the market matters far less than buying the right property at a payment that works.
10. The agent you choose changes the outcome
In a market this competitive, representation is not a formality.
The difference shows up in the details — knowing which listing agents respond to which terms, structuring an offer that wins without overpaying, spotting a problem in the disclosures before it costs you, knowing what a house is actually worth versus what it's listed for, and having inspectors, lenders, and contractors who pick up the phone.
Ask any agent you're interviewing how many transactions they closed in the last twelve months, how many were in the neighborhoods you're targeting, and how they handle multiple-offer situations. The answers will tell you a lot.
Final thoughts
Buying in San Diego is very doable. It just rewards preparation more than most markets do. Get your financing sorted early, understand your real monthly number, pick your location carefully, read the HOA documents, and work with someone who does this every day in the neighborhoods you're targeting.
