January is traditionally the quietest month in Silicon Valley real estate. Fewer listings hit the market, and many buyers are still in planning mode after the holidays. But January 2025 tells a different story. Demand has carried over from a strong fall market, and the limited inventory that defined 2024 shows no signs of easing. Here is what the data reveals.
January 2025 by the Numbers
- Median sale price: $1,780,000, up 4.2 percent year-over-year.
- Active inventory: Just 0.9 months of supply, the lowest January reading in three years.
- Average days on market: 12 days for single-family homes, with well-priced homes in top neighborhoods going pending in under a week.
- Sale-to-list price ratio: 104 percent, indicating most homes are selling above asking price.
- New listings: Down 18 percent compared to January 2024, reflecting the ongoing lock-in effect.
What Is Driving Early-Year Demand
Tech Sector Strength
The AI boom continues to fuel housing demand in Santa Clara County. NVIDIA, headquartered in Santa Clara, saw its stock price triple in 2024, creating significant paper wealth that is now translating into home purchases. Apple, Google, and a growing ecosystem of AI startups are generating new high-income buyers entering the market with urgency.
Rate Lock-In Suppressing Supply
An estimated 80 percent of homeowners in Santa Clara County hold mortgages with rates below 4 percent. Moving would mean taking on a 6.5 percent rate on a new purchase, effectively doubling their monthly payment even if the home price remained the same. This dynamic keeps inventory artificially low and gives the limited number of listings outsized negotiating power.
Pent-Up Buyer Demand
Many buyers who were outbid or sidelined in the fall of 2024 entered January with renewed determination. Pre-approval activity among my own clients picked up markedly in the first two weeks of the year, suggesting a competitive spring market ahead.
City-Level Highlights
- Cupertino: Median $3.0 million. The tightest inventory of any South Bay city, with just 12 active single-family listings countywide in the Cupertino school district.
- Los Altos: Median $3.9 million. Lot-value teardowns and mid-century homes on larger lots continue to attract builders and affluent families.
- Sunnyvale: Median $2.0 million. Strong demand in the $1.6 to $2.2 million range from dual-income tech families.
- Mountain View: Median $2.1 million. Proximity to Google's campus sustains premium pricing, with townhomes offering entry points around $1.3 million.
- San Jose: Median $1.35 million countywide, but the Willow Glen submarket commands $1.6 million plus for character homes on tree-lined streets.
What to Expect in the Coming Months
January's data strongly suggests that the spring market will be competitive, possibly more so than 2024. Inventory is unlikely to increase meaningfully until mortgage rates drop below 5.5 percent, which most economists do not expect before late 2025 at the earliest.
For buyers, the strategy is clear: get pre-approved now, define your target neighborhoods, and be prepared to move decisively when the right listing appears. For sellers, the window from mid-February through May will offer the strongest buyer traffic and the best conditions for achieving a premium sale price.
The Bottom Line
Santa Clara County's January 2025 market data confirms what agents on the ground already know: demand is strong, supply is tight, and well-prepared participants on both sides of the transaction are being rewarded.
