San Diego Housing Market Update: September 2026

September is here, and the San Diego housing market is in a place I have not seen in a while: rates are climbing while inventory stays frustratingly tight, a combination that rewards preparation over rushing. If you have been waiting for a clear signal on whether to buy, sell, or invest, the latest data points one way, so let me walk you through it honestly.

After 18+ years as an agent, investor, and military spouse across San Diego County, I have learned that the market is always telling you something. Right now the story starts with mortgage rates and ends with a simple truth: opportunity in San Diego has not disappeared, it has moved. Let me show you where.

The September 2026 Market Snapshot: What the Data Says Right Now

Let us start with the number driving every conversation in my office. The 30-year fixed rate is at about 6.70% to 6.72% in the first week of September, according to NerdWallet, Money.com, and MortgageDaily, with Freddie Mac's weekly average near 6.66% at the end of August. That is well above the high-5-percent range of early 2026, and forecasts expect it to hold through September. For buyers, every half point costs real buying power. For sellers, it anchors would-be trade-up owners to the financing they already have.

The rest of the picture comes from Redfin, the St. Louis Fed's FRED database, and local MLS reports.

Prices are high and holding. The county-wide median sale price was about $952,000 for the three months ending June 2026, up 3.9% year over year. July's median came in near $1.02 million after the record-setting June figure of roughly $1.05 million, and the median listing price in July was about $922,500. The takeaway is that prices are not collapsing. They are stabilizing at a level that is simply unaffordable for many, which shapes everything else about this market.

Inventory is still scarce. San Diego County runs at roughly 2.4 months of supply, and active listings were about 8,100 in the mid-summer count, down 2.5% from a year earlier. New listings are down double digits year over year because owners with low-rate mortgages will not give them up. It is the lock-in effect, the single strongest force holding supply back.

Days on market are stretching. Redfin's data shows homes selling after about 27 days, while FRED's listing-based measure shows a median of 45 for the county. Either way, homes are taking longer to sell than a year ago, which gives buyers breathing room and means sellers cannot count on a quick sale.

Sales are happening, with concessions. Closed sales ran about 9.5% higher than a year ago in June, and sellers are increasingly offering 1% to 3% in credits or concessions to close near asking. That is a normalizing California market: not crashing, just requiring more skill.

Why Rates Are the September Story

The early-2026 hope was that rates would ease toward 5.9%. Instead they spiked to the mid-six-percent range and are sitting there now. That cools demand just enough to take the edge off bidding wars, and it deepens the lock-in: families with 3% and 4% mortgages will not reborrow at 6.7%, so the best-priced listings stay off the market.

I wrote more about the Federal Reserve's rate path in my breakdown of the Fed's decision and what it means for buyers and sellers. The short version: rate-sensitive buyers are staying careful but active, and that is exactly what makes the buyers who move now competitive.

What This Means for Buyers: More Room, Same Edge

This is quietly one of the better buyer windows we have had since the pandemic. Competition is down, homes sit long enough to think, and seller concessions are back on the table. The challenge is financing: at 6.7%, the payment on a $950,000 median-priced home stretches budgets, so get pre-approved, know your non-negotiables, and be ready to move when the right home appears.

For first-time buyers, the path usually runs through attached homes in neighborhoods like Mission Valley, North Park, Normal Heights, or Chula Vista, where you can enter well under the median and build equity from there. My Buying Guide walks through pre-approval, offers, and negotiation built for this exact market.

For military buyers, your advantage is even bigger right now. VA loans still offer a zero down payment, no private mortgage insurance, and some of the strongest rates in the market, and with homes sitting longer, you finally have time for the VA appraisal without racing contingencies. If you are PCSing to Camp Pendleton, Naval Base San Diego, or MCAS Miramar this fall, this is a strong window. The Military and Veterans page has the neighborhood and financing strategy from someone who has done the moves herself.

What This Means for Sellers: Pricing and Preparation Win

If you have been waiting to sell, hear me on this: the market has not crashed, but it no longer rewards listing overpriced and hoping for a bidding war. The first two weeks of a listing are still the most critical. That is when you get the most showings, and homes that are priced right, staged smartly, and photographed professionally are still selling close to asking within 30 days. Homes that are not sit.

Pre-sale repairs matter more now, because buyers with choices will not overlook deferred maintenance when they can ask for a credit. My article on pre-sale home repairs that actually pay off in 2026 covers what is worth doing, and the full playbook, from pricing and staging to concessions and negotiation, is on my Selling Guide.

What This Means for Investors: Patience and Creativity

Investors are facing the same rates as everyone else, and that has cooled the rush to buy at the top. That is not bad news. The hurried deals fall away, serious buyers find better entry points, and sellers are more willing to negotiate.

The rental side has softened with new apartment supply, so long-term hold numbers deserve care. That is where my investor and commercial contracting background comes in: when I look at a fixer, I can price the work in a few hours, and that margin between list price and true value is where the September opportunity lives. Start with value-add properties and neighborhoods near bases, transit, and hubs like the RADD District.

If you are deciding whether to hold, sell, or buy a San Diego investment, I would love to run the numbers with you the same way I run them for my own portfolio. The Investment Properties page walks through how that analysis works.

Where Are You Headed Next?

Here is how I think about September. The rates are not your friend, but the supply is, and that trade-off has quietly produced the most negotiable market we have seen in years. If you are a buyer, come prepared and use the timing. If you are a seller, price with honesty and prepare like the results depend on it. If you are an investor, the edge belongs to people who see what others miss and structure financing creatively.

What is your biggest challenge? Where are you headed next? That is where I start every conversation, because the right decision depends on your situation, not on what the market is doing for your neighbor. Clear data, honest guidance, and a relationship built on trust are how I have served every client for 18+ years, and how I would serve you.
