What's My San Diego Home Worth?

Automated estimates work by pattern: they look at recent sales of statistically similar homes and interpolate yours. In a newer tract suburb where every fourth house is the same floor plan, that works pretty well. Central San Diego is the opposite of that. The housing stock is seventy years old and every house has lived its own life: one got a permitted second story in 1998, the next is untouched since 1962, the third had its garage converted without a permit sometime during the Reagan administration. Same street, same square footage on paper, three very different values.

The algorithm also can’t see what decides deals here. It doesn’t know your kitchen was gutted in 2022 or that your “updated” neighbor’s update was a flip with unpermitted plumbing. It doesn’t know the freeway hum on your side of the block, or that your back fence is a canyon rim with a Mission Bay view. It reads county records and listing photos, and in a market of one-off mid-century homes, that’s a guess wearing a decimal point.

Use the portal number the way I do: as a rough anchor and a trend line. Just don’t price a sale, a divorce settlement, or a refinance argument on it.

When I value a home, these are the levers that swing the number, roughly in order of force:

1. Location inside the neighborhood. West of the 5 carries a premium. So does a canyon-rim lot on Tecolote or Marian Bear, a view of the bay, or a quiet interior street versus a cut-through. In Clairemont, even the zip matters: 92117 addresses price ahead of comparable 92111 ones, and locals search by zip.
2. School boundary. The blocks feeding Holmes Elementary, a 9 on GreatSchools, sell measurably stronger than blocks two streets over. Boundaries are block-specific and they shift, which is exactly why an algorithm averaging across a whole zip gets this wrong.
3. Condition and era of the systems. Roof, sewer lateral, electrical panel, plumbing. On 1950s and 60s housing stock, the invisible systems can swing a negotiation $30,000 to $60,000, and buyers’ inspectors will find them whether the estimate did or not.
4. Permit history. Permitted additions count at full value. Unpermitted square footage counts at a discount, sometimes at zero, and occasionally as a liability. This is public record, and I pull it on every valuation.
5. Lot and ADU potential. A 6,000+ square foot lot with alley access is worth more than the same house on a hemmed-in lot, because the ADU math works. A permitted ADU already in place, earning rent, moves the number further. Appraisers credit ADUs inconsistently, which is worth knowing before you build one purely for resale; the ADU guide covers that trade-off.
6. The market’s direction. Values drifted down about 2.3 percent citywide over the past year as of mid-2026. A comp from nine months ago isn’t a comp; it’s history.

CMA stands for comparative market analysis, and it’s what an agent does instead of an algorithm. Mine runs like this.

I start with sold prices, not list prices, because asking is an opinion and selling is a fact. I pull closed sales from the last three to six months in your immediate pocket, not the whole neighborhood: the same side of the freeway, the same school boundary, the same kind of street. In Point Loma, a comp from the wrong sub-neighborhood can be off by hundreds of thousands; the median there ran about $1.695M as of Q3 2026, but La Playa and Loma Portal are different markets wearing the same zip.

Then I adjust for what the records can’t say, which requires actually standing in your house. Condition, light, layout, the remodel’s quality, the systems’ age, the noise at 5 pm. My construction background does real work here: I can tell a $150,000 renovation from a $40,000 cosmetic pass, and I know which one the buyer’s inspector will unmask.

What you get is a range and a strategy, not a single magic number. “Your house should sell between X and Y; here’s the pricing approach for each, and here’s the one repair that moves you from the bottom of the range to the middle.” A valuation that ends in one proud number is a sales pitch. A valuation that ends in a range and a plan is work product.

A quick decoder, because the headlines mix these up constantly. The citywide average sits near $1,007,800 as of mid-2026. Clairemont’s single-family median ran $1,142,500 early in the year, with condos and townhomes near $535,000. Point Loma’s median is around $1.695M. None of these contradict each other; they’re different neighborhoods and different math. Medians also move when the mix of what sold moves: a quarter heavy with fixer sales drags the median down without your house losing a dollar.

The practical takeaway: neighborhood-level numbers tell you the weather. Only comps from your blocks tell you your house. When a headline says the market fell, and your pocket had three renovated sales close strong that quarter, the headline is true and irrelevant.

Sellers ask this constantly, so, opinions:

Reliably worth it before selling: paint, landscaping cleanup, fixing the small stuff, and light staging. Cheap, fast, photographs well.

Worth it over your ownership, partially recovered at sale: kitchens, baths, and systems done with permits. You’ll enjoy them for years and recover a share, not all, of the cost. Doing them purely to sell usually loses money; the selling guide goes deeper on fix-versus-skip.

Undervalued by sellers, valued by buyers: the boring systems. A replaced sewer lateral, a new panel, a newer roof. They don’t photograph, and they defuse the exact inspection items that cost sellers real credits in escrow. On a 1950s house, “sewer replaced 2024” in the listing remarks is worth more than a quartz countertop.

Consistently overvalued by owners: pools, expensive personal-taste finishes, and unpermitted additions. That unpermitted bonus room you count at 400 square feet, an appraiser may count at zero and a buyer’s agent may count against you.

Pricing off the neighbor’s asking price. Their list price is a hope, not a comp. Wait for the sold price; it’s often a different conversation.

The agent with the flattering number. Some agents win listings by quoting high and cutting later. Ask for the sold comps behind any number an agent gives you, including mine. If the comps aren’t from your pocket and the last six months, keep interviewing.

Counting unpermitted square footage at full value. Covered above, but it’s the most common gap between what owners believe and what escrow proves.

Valuing from the 2022 peak. “We were worth $1.3M in 2022” may be true and doesn’t matter. The market has drifted down since; your buyer lives in 2026.

How accurate is the Zestimate for San Diego homes? Good enough for a trend, not for a decision. Automated estimates struggle with central San Diego’s one-off mid-century housing stock, where permits, condition, views, and school boundaries swing values block by block in ways county records don’t capture.

How much is my San Diego home worth right now? The citywide average is about $1,007,800 as of mid-2026, down 2.3 percent year over year, but your pocket may sit well above or below that. The only reliable answer comes from sold comparables on your blocks, adjusted for your home’s condition and permits.

What is a CMA, and what does it cost? A comparative market analysis: an agent’s valuation built from recent sold comps in your immediate area, adjusted in person for condition, systems, and location. Mine is free, with no listing agreement attached and no follow-up campaign afterward.

Does an ADU increase my home’s value? Usually, especially a permitted one that’s already rented, though appraisers credit ADUs inconsistently. Lot potential itself adds value too: a 6,000+ square foot lot with alley access is worth more than the same house without it. Unpermitted conversions can subtract value.

Should I get a valuation if I’m not selling yet? Yes. Knowing your real number helps with refinancing, insurance, ADU decisions, and timing. Most sellers I work with started with a valuation a year or more before they listed, and the ones who did made cheaper, calmer decisions.

Send me your address and I’ll put together a proper CMA: sold comps from your blocks, a walk-through if you’ll have me, and an honest range with the reasoning shown. Free, no listing agreement required, and no drip campaign afterward. If the honest number is lower than you hoped, you’ll hear that too, along with the one or two things that would change it.
