December 2025 Data What It Signals for 2026
San Diego’s housing market is heading into 2026 with a familiar (and powerful) theme: inventory is tight, pricing is holding firm, and the “pace” of the market depends heavily on interest rates and consumer confidence. The December 2025 Monthly Snapshot (San Diego MLS, current as of January 5, 2026) gives us three headline numbers that tell the story clearly.
The three key one-year changes (all property types)
From page one of the report, here are the year-over-year changes for All Properties:
- Closed Sales: down 6.3%
- Median Sales Price: up 3.0%
- Homes for Sale (Active Inventory): down 50.6%
If you only read one paragraph, read this: Sales volume fell, prices rose, and inventory got cut in half. That combination is the clearest explanation for why San Diego can feel “slow” in activity while still remaining “strong” in values.
1) Closed sales down 6.3%: demand didn’t disappear — the market’s flow got restricted
A 6.3% decline in closed sales year-over-year tells us fewer transactions completed, but it does not automatically mean the market is weak.
In a low-inventory environment, closings often fall for two reasons:
A) Fewer homes are available to buy
When the number of homes for sale drops as dramatically as it did (more on that below), the market’s “capacity” shrinks. Even when motivated buyers are present, there are simply fewer acceptable options to purchase.
B) The market becomes more rate-sensitive
San Diego buyers are payment-driven. When rates rise, many buyers pause; when rates ease, many buyers re-enter—fast. That creates “start/stop” behavior that can reduce total annual closings even when prices are steady.
What this tends to mean for 2026:
If inventory stays low (likely), closed sales in 2026 will be heavily influenced by two swing factors:
- whether mortgage rates trend lower, and
- whether consumer confidence improves amid global uncertainty.
2) Median sales price up 3.0%: the market still has pricing power
Despite fewer closed sales, the median sales price rose 3.0% year-over-year for all properties. That is a big clue about “where the leverage” is in San Diego:
A) Low supply puts a floor under prices
When homeowners don’t list (or can’t afford to give up a low mortgage rate), supply stays constrained. That tends to reduce the chance of broad price declines because buyers compete for a small pool of quality homes.
B) San Diego is a “sticky” pricing market
Even in slower periods, many sellers in San Diego don’t need to sell. That matters because discretionary sellers often choose to wait rather than cut aggressively—especially when they have strong equity positions and fixed low payments.
What this tends to mean for 2026:
If rates ease and more buyers return, pricing pressure can reappear quickly—not necessarily across every neighborhood equally, but especially in well-located, move-in-ready homes and properties with desirable features (views, lot size, ADU potential, walkability, etc.).
3) Homes for sale down 50.6%: this is the headline that shapes everything
The most important number on page one is the inventory shift: Homes for Sale down 50.6% year-over-year (all properties).
A decline of this size is market-moving. It impacts:
- buyers (fewer choices, more competition on the “good ones”)
- sellers (stronger negotiating position when the home is priced correctly)
- prices (supportive environment, because scarcity creates leverage)
- days on market (often splits: great homes move fast; “compromises” sit)
And it also explains the contradiction many people feel:
- “It doesn’t seem that busy,” and also
- “Prices aren’t really coming down.”
With inventory reduced this sharply, the market can feel quieter simply because fewer homes are available to transact—yet prices can still rise because the supply-demand balance stays tight.
What this points to in 2026: low inventory + uncertainty + the rate wildcard
Heading into 2026, I’d frame San Diego’s market outlook like this:
1) Inventory is likely to remain low (unless something forces more listings)
The data already shows an extremely constrained environment, and this is often reinforced by the “lock-in effect” — homeowners holding onto low mortgage rates and choosing not to sell unless they have a strong life reason. With homes for sale down 50.6%, the baseline expectation is a continuing shortage unless a major catalyst changes seller behavior.
2) Global events and economic uncertainty are the “confidence” variable
Uncertainty tends to delay decisions—especially for discretionary buyers and sellers. In 2026, confidence could be affected by global events, inflation expectations, employment trends, and market volatility. When confidence drops, activity slows. When confidence rises, activity rebounds.
3) Lower interest rates could spark demand quickly
Rates are the accelerant in San Diego. If interest rates move lower, a few things usually happen fast:
- buyers who paused re-enter the market,
- purchasing power improves,
- demand concentrates on the best inventory first,
- competition increases—often before inventory has time to rebuild.
In a market where inventory has already been cut in half, lower rates can create a quick shift from “patient buyers” to “urgent buyers.”
Practical takeaways for San Diego buyers and sellers in early 2026
If you’re buying in 2026
- Expect limited options and be ready to act when the right home appears (inventory is the constraint, not demand).
- Watch rates closely. If rates drop meaningfully, you may see more competition almost immediately.
- Strong preparation matters: underwriting, clear terms, and knowing your “must-haves vs. nice-to-haves” before you shop.
If you’re selling in 2026
- A low-inventory environment can be a major advantage if your home shows well and is priced realistically.
- The market can be less forgiving on homes that feel overpriced or need substantial work—buyers may have fewer choices, but they’re still value-conscious.
- Timing can matter: if rates soften, demand can rise quickly, often improving showing traffic and offer quality.
Bottom line: 2026 is shaping up to be a “tight-supply market” with a rate-driven upside
The page-one metrics tell a consistent story:
- Closed sales down (–6.3%) suggests a market that’s been constrained in transaction volume.
- Median price up (+3.0%) shows San Diego still has pricing resilience.
- Inventory down (–50.6%) is the core driver—this is what keeps the market supported and sets the stage for a potential demand surge if rates fall.
If 2026 delivers lower interest rates, San Diego has the ingredients for a more active market—even with global uncertainty—because demand doesn’t need to explode to create competition. With inventory this limited, it only takes a modest increase in buyer urgency to spark noticeable movement.
