San Diego Real Estate Market Update September 2026

A detailed analysis of August 2026 San Diego County housing data

Prepared for DawnSellsSanDiego.com | September 2026

The August 2026 numbers show a San Diego housing market that remained expensive and supply-constrained, but noticeably slower in transaction volume. The countywide median sales price reached $965,000, up 7.1% from August 2025. At the same time, closed sales fell 17.1% and pending sales declined 12.0%. Buyers were still willing to pay for the right property, but fewer purchases reached the closing table during the month.

That combination matters. Rising prices alone can make a market appear stronger than it is, while falling sales alone can make conditions appear weaker than they are. In August, both were true: values held up, especially for detached homes, while affordability and financing costs limited the number of buyers able or willing to act. This was not one uniform market. Detached homes and attached homes produced very different inventory, pricing and negotiation conditions.

After more than 35 years working in San Diego real estate, I have learned that countywide headlines are only a starting point. A home's neighborhood, property type, price range, condition and competition determine its actual market. The August data provides an important guide, but sellers and buyers should apply it to the specific part of San Diego County in which they plan to move.

San Diego County Market at a Glance

Year to date, the market was steadier than the August snapshot. Through August, closed sales were up 1.7%, pending sales were up 2.1%, the median price was up 2.2%, and closed dollar volume was up 4.4% compared with the same period in 2025. New listings, however, were down 4.2%. This indicates that August's sharp decline in closings should be read in the context of an otherwise modestly positive year, not as proof that the entire 2026 market had reversed direction.

Prices Increased Even as Sales Slowed

The countywide median sales price increased from $901,000 in August 2025 to $965,000 in August 2026. The average price rose from $1,219,823 to $1,249,153. Median and average prices measure different things. The median identifies the midpoint of all sales, while the average can be pulled higher by expensive coastal and luxury transactions. Both measures moved upward, but the stronger increase in the median suggests that price support extended beyond a handful of high-end sales.

Price strength was concentrated in detached homes. Their August median reached $1,120,000, a 4.7% annual increase, while their average price rose 3.3% to $1,477,488. Attached properties, including condominiums and townhomes, had a median price of $670,000, only 0.1% above the prior year. Their average price declined 0.2% to $815,393.

The year-to-date figures reinforce that divide. The detached median was $1,100,000, up 2.6%, and the detached average was $1,455,391, up 3.7%. The attached median was $665,000, down 0.7%, while the attached average was $805,501, down 1.3%. San Diego homeowners should therefore avoid treating the countywide 7.1% August median increase as the appreciation rate for every property. Detached and attached homes were following different paths.

Sales Activity Lost Momentum in August

San Diego County recorded 1,714 closed sales in August, down from 2,068 one year earlier. Pending sales fell from 2,079 to 1,830. Because pending sales generally lead closings, the 12.0% decline in accepted offers suggested that early fall closings could remain restrained unless buyer activity improved.

Detached closed sales declined 17.6% to 1,118, and detached pending sales fell 14.0% to 1,158. Attached closed sales declined 16.3% to 596, while attached pending sales fell 8.2% to 672. Lower activity did not automatically translate into lower prices because the number of available detached homes also declined sharply.

The total dollar volume of August closings fell 15.1% to approximately $2.13 billion. Detached volume declined 14.7% to $1.65 billion, and attached volume declined 16.8% to $479 million. These figures reflect fewer transactions, not a broad 15% decline in individual home values.

Inventory Revealed Two Different Markets

At the end of August, San Diego County had 5,650 homes for sale, 10.0% fewer than a year earlier. Overall supply measured 2.9 months, down from 3.3 months. A months-supply calculation compares active inventory with the pace of pending sales during the previous 12 months. It is a useful measure of market balance, although conditions can vary considerably by community and price range.

Detached inventory dropped 20.7% to 2,883 homes. Supply fell from 3.0 months to 2.3 months. That remains a relatively tight market and helps explain why detached prices rose even though fewer homes sold. Buyers competing for desirable single-family homes still faced limited selection, particularly when a property was well located, updated and priced correctly.

Attached inventory moved in the opposite direction. There were 2,767 attached homes for sale, up 4.6%, with supply holding at 4.0 months. New attached listings increased 7.5% during August and were up 3.6% year to date. Buyers shopping for condos and townhomes generally had more choices and more room to compare value, condition, homeowner association costs and financing requirements.

New Listings Did Not Tell One Simple Story

Countywide new listings increased 1.3% in August to 3,125, yet they remained down 4.2% year to date. Detached new listings declined 2.9% for the month and 9.2% year to date. Attached new listings increased 7.5% for the month and 3.6% year to date.

For detached-home sellers, reduced competition could be an advantage, but only if the home entered the market with a sound pricing and presentation plan. For attached-home sellers, rising competition made it more important to understand recent comparable sales, current active listings, HOA dues, insurance considerations, owner-occupancy rules and any assessments that could affect a buyer's decision.

Homes Sold Close to Asking Price

Across all property types, sellers received an average of 97.8% of their original list price, compared with 96.7% a year earlier. Detached homes received 98.0%, up from 96.6%. Attached homes received 97.2%, up from 97.0%. These percentages do not account for seller concessions, so they should not be interpreted as the seller's net proceeds.

The improvement is meaningful, but it does not mean sellers could choose any price and expect to receive nearly all of it. The statistic includes homes that may have adjusted their asking price before selling, and it is an average across the county. A property priced above its supportable range can still lose valuable exposure, accumulate market time and invite buyers to question why it has not sold.

Market Time Varied by Property Type

The typical closed sale took 38 days to sell countywide, three days faster than August 2025. Detached homes averaged 35 days, down 10.3%. Attached homes averaged 44 days, up 2.3%. Year to date, attached market time was 44 days, 10.0% longer than the same period in 2025, while detached market time held at 35 days.

These figures measure the time until a property went under contract, not the full period through closing. They also combine homes that sold immediately with those that required weeks of exposure or price adjustments. A well-prepared property can outperform the average, while a home with deferred maintenance, weak presentation or an aggressive price can take much longer.

Affordability Remained the Main Constraint

The countywide Housing Affordability Index declined from 48 to 44. The index estimates whether the median household income is sufficient to qualify for the median-priced home under prevailing interest rates; a higher number indicates greater affordability. The detached index fell from 40 to 38, while the attached index held at 64.

The gap helps explain why attached properties remain an important entry point for many buyers, even as HOA dues and other ownership costs must be evaluated carefully. For detached buyers, monthly payment sensitivity remained significant. A modest change in mortgage rates, insurance premiums or property taxes can alter purchasing power more than a small movement in the asking price.

What the August Data Means for San Diego Home Sellers

Detached-home sellers entered September with less competition than they had a year earlier, but also with fewer active buyers completing purchases. That market can reward a strong listing, yet it can expose an overpriced or poorly presented home quickly. The first two weeks on the market remain especially important because that is when a listing receives its greatest concentration of attention from active buyers and agents.

Attached-home sellers faced a more balanced environment with 4.0 months of supply and more listings than a year earlier. Buyers could compare similar units, buildings and communities more easily. Sellers should provide complete HOA documents promptly, address obvious condition issues, explain meaningful improvements and price against both recent closed sales and current competition.

A successful September listing strategy should include a property-specific market analysis, thoughtful preparation, professional photography and marketing, direct communication with showing agents, and a disciplined review of buyer feedback. Price should reflect the home's actual location, condition, lot, view, upgrades and competitive set rather than a countywide headline.

What the August Data Means for San Diego Home Buyers

Buyers should recognize that slower sales did not produce a countywide price decline. Waiting for a broad collapse that is not visible in the data could mean missing a home that fits both the buyer's needs and long-term budget. At the same time, buyers had more leverage in parts of the attached market and on listings that had been available longer, needed work or were priced above recent comparable sales.

For a desirable detached home with 2.3 months of supply, preparation still mattered. Buyers should obtain a fully reviewed loan approval, understand their cash requirements, study comparable sales before writing, and decide in advance which terms they can adjust. Price is only one part of an offer; the deposit, contingencies, closing schedule, appraisal risk and the seller's moving needs can also affect acceptance.

Condo and townhome buyers should examine the complete cost and risk picture. That includes monthly dues, reserve funding, pending assessments, litigation, insurance coverage, rental restrictions and lender eligibility. A lower purchase price does not necessarily mean a lower or safer monthly obligation.

The September 2026 Market Outlook

August's pending-sales decline points to a potentially slower closing pace in early fall. Seasonal moderation is also common after the summer market. Even so, detached supply remained too limited to support a blanket prediction of falling prices. If mortgage rates ease, demand could respond quickly because many prospective buyers have postponed rather than abandoned their plans.

The most likely near-term pattern is continued variation. Properly priced detached homes in desirable San Diego neighborhoods may continue to sell quickly and close near asking price. Attached homes and properties with condition, HOA or pricing challenges may require more time and negotiation. Interest rates, new-listing volume and the number of price reductions will be important indicators to watch in September.

No countywide report can predict the result for a particular property. A coastal home, an East County single-family residence, a North County condo and a South Bay townhome can experience different levels of demand during the same week. Local analysis is essential before making a pricing, offer or timing decision.

Should You Buy or Sell Now

For sellers, the decision depends on the property's competitive position and the owner's next move. Limited detached inventory can create a favorable opening, but buyers remain payment-conscious and selective. Sellers who need to buy another home should coordinate the sale, financing and replacement purchase before going on the market.

For buyers, August offered more negotiating room in certain segments without eliminating competition for the best homes. A buyer with stable finances, a comfortable payment and a long-term reason to own may find worthwhile opportunities. The right question is not whether every San Diego home will rise or fall next month. It is whether a specific home is fairly priced, financially sustainable and appropriate for the buyer's plans.
