August inverted the usual relationship between volume and price. Fewer San Diego homes changed hands than in any August in recent years, and the ones that did sold for materially more. Closed sales fell 17.1 percent year over year while the month's median price rose 7.1 percent. Here is what the data says, and what it means for your investment strategy.
The August 2026 snapshot
These are the trailing twelve-month figures, the same basis we track month to month.
| Metric | August 2026 | Year-over-year |
|---|---|---|
| Overall median sales price | $910,000 | +1.1% |
| Single-family homes median | $1,075,000 | +2.4% |
| Condos & townhomes median | $665,000 | −0.7% |
| Active listings (countywide) | 5,650 | −10.0% |
| Months supply (single-family) | 2.3 | −23.3% |
| Months supply (condo & townhome) | 4.0 | 0.0% |
| Fastest-selling price range | $750,001 to $1,000,000 | 36 days |
| Slowest-selling price range | $5,000,001 and above | 81 days |
Fewer sales, higher prices
The month's own numbers are where the story lives.
| August-only metric | Figure | Year-over-year |
|---|---|---|
| Closed sales | 1,714 | −17.1% |
| Pending sales | 1,830 | −12.0% |
| New listings | 3,125 | +1.3% |
| Median sales price | $965,000 | +7.1% |
| Dollar volume of closed sales | $2.13B | −15.1% |
Transactions dropped by roughly one in six, dollar volume fell 15.1 percent, and the median still climbed to $965,000 from $901,000 a year ago.
That combination is a mix shift, not a broad repricing. Sales fell hardest at the affordable end of the market while the expensive end held up, which pulls the median upward even when no individual house is worth more. The detached median rose 4.7 percent to $1,120,000. The attached median moved 0.1 percent, to $670,000. Almost all of the headline price gain came from what sold, not from across-the-board appreciation.
One month is not a trend, and the year-to-date figures say so plainly: closed sales are still up 1.7 percent on the year and dollar volume is up 4.4 percent. August was a sharp single month inside a year that remains slightly positive.
The detached squeeze tightened again
Single-family supply keeps contracting. Detached inventory finished August at 2,883 listings, down 20.7 percent. Months supply fell from 3.0 to 2.3, a 23.3 percent decline, and that is genuinely tight by any historical standard.
Sellers are not replenishing it. Detached new listings came in at 1,778, down 2.9 percent for the month and down 9.2 percent year to date. Fewer than 16,000 detached homes have come to market all year, against more than 16,600 by this point last year.
The homes that did list moved well. Detached properties sold in 35 days, four days faster than last August, at 98.0 percent of original list price, up more than a point. Sellers on the detached side are still setting terms.
Condos are the other side of the ledger
Attached inventory rose 4.6 percent to 2,767 listings. It is the only segment in the county adding supply, and condo sellers are the only ones actively bringing product: attached new listings were up 7.5 percent for the month and 3.6 percent year to date.
Months supply sat flat at 4.0, nearly twice the detached figure. Days on market ticked up to 44, two and a half days slower than last August, and the median gained just 0.1 percent. Condo pricing is going sideways while condo supply grows.
It is also the only affordable entry left. The housing affordability index reads 64 for attached homes against 38 for detached. Buyers priced out of a house are not leaving the county; they are landing here.
The top of the market is running on its own clock
Over the trailing twelve months, pending sales in the $5,000,001-and-above band are up 19.9 percent, the strongest gain of any price range in the county. Homes of 6,001 square feet and above are up 9.7 percent.
That is a reversal worth noting. In July the leader was the $250,001 to $500,000 band at 13.0 percent. It has since cooled to 8.7 percent while the top of the market accelerated. The luxury tier is also the slowest to transact, at 81 days, against 36 days for the $750,001 to $1,000,000 range, which remains the most liquid part of the market.
The investor takeaway
A 20.7 percent contraction in detached inventory against a 4.6 percent increase in condo inventory is the single most actionable fact in this report. Those two segments are no longer in the same market.
On the detached side, competition for acquisitions is severe and getting worse. Supply is at 2.3 months, listings are selling in 35 days at 98 percent of original asking, and new inventory is down 9.2 percent on the year. Winning here requires speed, clean terms, and a willingness to transact off-market. It is not a segment where patience is rewarded right now.
Condos are the mirror image, and that is where the opportunity sits. Supply is building, pricing is flat, days on market are lengthening, and the affordability gap is pushing displaced buyers directly into the segment. Growing supply and flat pricing in an asset class with a structural demand tailwind is the setup disciplined investors look for. Underwrite to current rents, not to appreciation, and let the seller's holding costs do the negotiating.
The volume collapse deserves a clear eye. A 17.1 percent drop in closings with a 12.0 percent drop in pendings means fewer transactions are being created, not just fewer closing. If that persists into the fall it changes the picture. One month does not.
Looking ahead
September data will show whether August was a seasonal air pocket or the start of something slower. The specific number to watch is pending sales, which lead closings by roughly a month and are the earliest honest signal of demand. Watch whether condo inventory keeps building, and whether detached new listings finally respond to how tight that segment has become.
If you want this run against your own holdings or a target submarket, that is the conversation we have every month with clients.
