San Diego County
October 2026 Market Update
Based on September 2026 sales and market activity
Shirin’s Take
Sales slowed in both markets, but inventory told different stories.
Detached inventory was 12.5% below last September, while attached inventory was 5.8% higher. Closed and pending sales declined in both categories. The detached median remained above last year’s level, while the attached median was slightly lower. Those differences matter more than a single countywide headline.
September 2026 Statistics
Detached Homes
San Diego County
The detached median was $1,075,000, up 5.4% from September 2025. At the same time, sold listings declined from 1,292 to 1,135 and pending sales fell from 1,300 to 1,076. The higher median should not be read as evidence that sales activity strengthened.
Active listings were down 12.5% year over year, although they increased from 2,911 in August to 2,962 in September. New listings were almost unchanged from last September at 1,777, up 0.7%. Supply was 2.4 months on a closed-sales basis and 2.5 months on a pending-sales basis.
Average market time was 37 days, down from 41 last September but up from 35 in August. Sellers received 97.7% of original price on average. The median also declined from August’s $1,108,525, illustrating why the comparison period needs to be clear when discussing price changes.
For Buyers
There were fewer detached homes available than last September, but slower sales mean conditions still need to be assessed property by property. Compare asking prices with recent similar sales, condition and current competition before deciding how aggressively to offer.
For Sellers
Lower inventory does not guarantee a quick sale or a particular price. With closed and pending sales below last year, preparation and realistic pricing remain important. The higher county median is not a percentage increase to apply to your own home.
September 2026 Statistics
Attached Homes
Townhomes, Rowhouses + Condos · San Diego County
The attached median was $665,000, down 1.0% from last September. Sold listings declined from 727 to 632, while pending sales fell from 722 to 622. New listings increased 3.9% to 1,230.
Active inventory was 5.8% higher than last September, although it declined from 2,783 in August to 2,732 in September. Supply was 4.0 months on both the closed-sales and pending-sales measures. That remains higher than detached supply, giving buyers a different set of conditions to evaluate.
Average market time was 44 days, compared with 42 last September. Sellers received 97.2% of original price on average, unchanged year over year. The median’s modest decline does not mean every attached home changed in value by the same amount.
For Buyers
Attached homes offer more supply and a longer average market time than detached homes countywide. Compare units, HOA costs, condition and recent sales carefully. Negotiating room still depends on the specific property.
For Sellers
Inventory remained above last year while sales declined. Review the units buyers can choose instead of yours and price accordingly. A nearly steady county median does not remove the need for a property-specific analysis.
Looking Ahead
Pending activity deserves attention.
September pending sales were below last year in both categories. I will be watching whether that continues and how inventory responds. Detached homes still had less supply than attached homes, so buyers and sellers should look beyond the county headline to their neighborhood, property type and price range.

This October 2026 update uses September 2026 monthly SDMLS data exported from InfoSparks on October 14, 2026. Filters: San Diego County; Detached and Twnh/Townh/Rwh/Attch, reported separately. Year-over-year changes compare September 2026 with September 2025. August comparisons use August 2026 values from the same exports. Percentage change equals (September 2026 value minus September 2025 value) divided by September 2025 value, multiplied by 100, rounded to one decimal. Original-price ratios are converted from decimals to percentages; their changes are percentage-point differences: detached 97.7% minus 97.0% equals +0.7 points, and attached 97.2% minus 97.2% equals 0.0 points. Headline months supply uses the Actual (Closed) series. Forecast (Pending) supply is stated separately in the commentary; these are distinct source measures. Average Market Time and Average Active Market Time retain the export labels and are not combined. Medians describe the mix of properties sold and do not measure appreciation of an individual home. County figures differ from ZIP-code and neighborhood statistics. Data deemed reliable but not guaranteed. InfoSparks © 2026 ShowingTime Plus, LLC. Each office independently owned and operated.
