San Diego County's real estate market split hard in August. Prices kept climbing — the county median hit $965,000, up 7.1% year-over-year, its strongest gain of 2026 — but the transaction side of the market cooled sharply. Closed sales fell 17.1% and pending sales dropped 12%. Fewer deals happening. Higher prices on the ones that did.
The story underneath the headline is the widening gap between property types. Detached inventory is down another 20.7% year-over-year, keeping supply painfully tight for single-family buyers. Attached inventory is up 4.6% and finally hit a full 4.0 months of supply — the closest San Diego has been to a balanced condo market in years. If you're transacting right now, the property type matters more than any headline number.
The two-speed market at a glance
| Metric | Detached (SFH) | Attached (Condo/Townhome) |
|---|---|---|
| Median Sales Price | $1,120,000 + 4.7% | $670,000 + 0.1% |
| Closed Sales | 1,118 − 17.6% | 596 − 16.3% |
| Pending Sales | 1,158 − 14.0% | 672 − 8.2% |
| Inventory (end of August) | 2,883 − 20.7% | 2,767 + 4.6% |
| Months Supply | 2.3 − 23.3% | 4.0 0.0% |
| Days on Market | 35 − 10.3% | 44 + 2.3% |
| % of Original List Received | 98.0% + 1.4% | 97.2% + 0.2% |
| Housing Affordability Index | 38 − 5.0% | 64 0.0% |
The most important line in that table is the closed-sales gap: detached down 17.6% year-over-year, attached down 16.3%. Sales activity dropped across the board. What's holding prices up isn't buyer enthusiasm — it's the fact that detached inventory is at 2,883 homes (down 20.7% YoY) and there simply isn't much to compete for. Scarcity is doing the work.
The attached market flipped in a meaningful way this month. Inventory is up 4.6% year-over-year to 2,767 units and months-supply held at exactly 4.0 — well into balanced-market territory. Prices are essentially flat ($670K median, +0.1% YoY), and days-on-market ticked up slightly to 44 (+2.3%). Condo buyers who felt priced out earlier in the year have more room to negotiate and more choice than they've had in months.
Why sales dropped even though prices didn't
New listings in August were roughly flat year-over-year (+1.3% overall — detached down 2.9%, attached up 7.5%). But pending sales dropped 12% and closed sales dropped 17.1% — a much bigger cooling than listings would suggest. That gap tells you buyers pulled back too. It's not just a supply problem this month; demand softened alongside it.
A few likely drivers for the demand pullback:
- Sticker shock at $1.12M detached: the median single-family price is at an all-time high, and the year-over-year jump (+4.7%) is meaningfully higher than wage growth
- Mortgage rates still elevated: the affordability index for detached homes sits at 38, meaning median household income covers just 38% of what's needed to qualify for the median home at current rates
- Late-summer seasonality: August has historically been softer than July, and this year that pattern amplified rather than moderated
- National sentiment weakened: U.S. existing-home sales edged down 1.7% month-over-month, per NAR, with buyers watching rate trajectory rather than jumping in
The result: a market where the few well-priced homes still get multiple offers, the merely-decent ones sit longer, and the overpriced ones don't move at all. That dynamic is intensifying, not easing.
Days on market: detached still moving fast; condos taking longer
Detached homes sold in a median 35 days in August, down 10.3% year-over-year. Attached homes were at 44 days, up 2.3%. Detached is actually moving faster than a year ago despite the sales pullback — another sign that the properties that DO trade are trading briskly, but many potential buyers are staying on the sidelines.
Price adherence stayed strong: detached sellers are getting 98.0% of original list price, up 1.4% year-over-year. Attached is at 97.2%. When inventory is this scarce on the detached side, the well-priced homes are the ones getting multiple offers — the overpriced ones sit and eventually reduce. "List smart" still beats "list high."
What this means if you’re buying
Your experience depends heavily on which side of the market you're shopping on:
Detached buyers: The competition is still there for well-priced homes, but the softer sales month gives you a small window. Inventory is 20% tighter than a year ago and homes are selling in 35 days at 98% of original ask, so you still need pre-approval, ready financing, and street-level comps. But with buyer volume down, you're not always facing the 6-8 offer bidding wars we saw in spring. If a home has been sitting for 30+ days, that's often now an opportunity to negotiate rather than a signal something's wrong.
Attached buyers: Better environment than you've had in a long time. 4.0 months of supply is a balanced market by any traditional definition. Prices are essentially flat year-over-year, days-on-market is 44 days, and inventory grew 4.6% while sales fell. That's the definition of buyer's leverage. Well-priced condos still move, but you have time to see multiple properties, ask questions about HOAs, and structure a smart offer instead of stretching to compete.
Affordability reality check: The Housing Affordability Index for detached homes fell to 38 (down 5% YoY) — meaning the median household income is just 38% of what's needed to qualify for the median detached home at current rates. For condos, it's 64. That 26-point gap explains most of the two-speed dynamic: buyers who can't stretch to a $1.12M detached home are moving into the attached market by pure math, and even they are being more cautious this month.
What this means if you’re selling
Selling a detached home: Still a favorable environment despite the sales slowdown. Low competition, prices at all-time highs, homes moving in 35 days at 98% of ask. The catch is buyer volume: fewer buyers are actively shopping in August than in July, so your first-two-weeks window matters more than usual. Price it right the first time and present it well — the market rewards that combination more than aggressive pricing right now.
Selling a condo or townhome: More patience required than any point in the last 18 months. You're competing with more inventory (+4.6% YoY), sales are down 16.3%, and buyers know they have leverage. Presentation, price, and HOA transparency are the three variables that separate homes that sell in 30 days from ones that sit for 90. Updated units in walkable pockets like Little Italy, Downtown, and Hillcrest are still the fastest movers.
General rule: The 12-month average days-on-market is now 38 days for detached and 44 for attached — both up modestly from a year ago. Well-priced homes still take about six weeks from list to close on the single-family side, closer to two months for condos. Build that into your timeline.
YTD 2026: how the year is stacking up
Zooming out to the year-to-date view:
- Total closed sales YTD: 15,464 (+1.7% vs. YTD 2025)
- Median sale price YTD: $925,000 (+2.2%)
- Total dollar volume YTD: $18.84 billion (+4.4%)
- Detached YTD median: $1,100,000 (+2.6%)
- Attached YTD median: $665,000 (−0.7%)
2026 is still on pace to close ahead of 2025 on transaction count and dollar volume — but the August slowdown narrowed that lead. The stronger YTD dollar volume (+4.4%) on modest sales growth (+1.7%) reflects the price appreciation showing through, especially on the detached side.
National context
Nationally, existing-home sales edged down 1.7% month-over-month in August to a seasonally adjusted annual rate of 4.06 million units, according to the National Association of REALTORS®. The national median was $431,400, with inventory at a 4.6-month supply. Year-to-date national sales are up 2.4%.
San Diego is still running well ahead of the national median — both on price and on how tight the detached picture is. Our 2.3 months supply on the detached side is roughly half the 4.6-month national supply. That said, our attached supply now matches national norms almost exactly. Two distinct markets under one banner.
The bottom line
August was the sharpest divergence yet between the two San Diego markets. If you're transacting on the detached side, you're facing tight inventory, rising prices, and homes that still move quickly — but a thinner pool of active buyers than we saw in spring. If you're on the condo/townhome side, you have real leverage for the first time in years: more choice, flat pricing, and time to think.
For owners deciding whether to sell now or wait: detached prices are at record highs but buyer demand cooled this month, and September usually cools further. If you're planning to buy back into the same market, timing matters less than getting your specific property positioned well. If you're moving out of San Diego, this is still a favorable window on the detached side. Talk through the specifics before deciding.
