Cupertino SFH up 33% but multi-family down 23% — anyone else seeing this split?

Question

Something caught my eye in my weekly data pull for Santa Clara County and I wanted to get some perspective from other multi-family investors.

Cupertino's overall residential market is on fire right now — median sale price hit $3.24M, up 33.4% year over year, with homes selling in just 10 days. But the 2-4 unit segment there tells the opposite story: median sale at $2.19M, down 23.2% YoY, sitting on market for 104 days on average.

And the days-on-market spread across the South Bay for multi-family is wild. San Jose duplexes are moving in 9 days. Mountain View multi-family? 94 days. Saratoga? 182 days. It's like two completely different markets depending on which city you're in.

My working theory is that buyers in the premium suburban markets at those price points just default to single-family, so multi-family inventory lingers. Meanwhile San Jose still has enough investor demand (and lower entry points around $1.43M median) to keep velocity up.

Would love to hear from anyone actively investing in South Bay or similar high-cost metros — are you seeing this kind of SFH vs. multi-family divergence in your market too? Or is this just small sample noise in the pricier suburbs?

I dig into this data every week for Santa Clara County — happy to pull numbers for specific cities or ZIPs if it'd be useful.

Still a limited number of SFRs for people to live in.

The tenant protection laws at both state and local levels are out of balance coupled with increased expenses (insurance up 60-100% in a lot of cases) giving people pause to invest in Multi-family properties.  The risks are higher and the returns are lower.

Is no SFR buyer there enough of a visionary to buy the SMF for a $1M discount and turn it in to their dream SFR? Maybe they’re much smaller, or older? Or are they just in bad neighborhoods?

I understand saving $1M in CA isn’t like saving $1M in a reasonable state. But they still have to earn almost $2M before taxes to get that same $1M. Seems like a no brainer, unless the properties aren’t really comparable, in which case maybe they’re shouldn’t be.

@Ryan Winston I can't say what insurance changes have been for medium to large multi-family properties as I don't manage that class.   I was speaking about 3-8 unit residential and commercial properties (think strip malls (3-10 spaces) and industrial).

The SFR market is doing well.  No price pull backs in that area for sure. Instead of 10 offers you are getting 2-3.  Both still in a relatively short period of time, less than a month.

Use real data when analyzing your deals, not the data provided by sellers.  If you need to call insurance agents with a property address to get an accurate number do that.

The only other item I can think of that is fairly new in San Jose is soft-building compliance.  Basically tuck-under parking needs to be evaluated to pass the new laws. May be a very expensive fix if not compliant.

As a boots on the ground agent, I can confirm - Cupertino and Sunnyvale markets are insane. We are seeing multiple cash offers well above asking on a regular basis.Many of these are AI-driven wealth with demanding jobs and are just getting started in real estate, so naturally SFHs are their top priorities. For small multi-family (<4 units), the numbers just don't pencil out for small funds and investors at those premium zip codes. Especially in Mountain View, there are upward pressures from builders. Several large apartment complexes were recently approved by the city.

Ryan Winston · Answer

Wilson, that agent-level context is super helpful. The data I pull weekly backs up exactly what you're describing. Sunnyvale multi-family is sitting at 42 days on market, while the overall residential market there moves in 9 days. That's a massive liquidity gap within the same city, and the AI-wealth-to-SFH pipeline you're seeing explains it.

The Mountain View builder pressure is really interesting, too. Only 4 multi-family listings there right now, but they've been sitting for 94 days. If new large complexes are getting approved, that incoming supply could keep pushing small multi-family values down further. Are you seeing any of those tech buyers start looking at San Jose for a second property, or is multi-family demand mostly coming from a different buyer profile entirely down there?

Also, I'm relatively new to all this and looking for more data to pull. Let me know if you have any suggestions on what else would be interesting to dig into.

Chad, the insurance numbers you're quoting are eye-opening. 60-100% increases completely change underwriting for a small multi-family, even when rents are holding. I've been focused on the gross yield side in my weekly data pulls, but that expense pressure explains a lot about why the multi-family correction is steeper than I'd expect from demand alone.

Your point actually connects to something I looked at recently on the regulatory side. The AB 1482 owner-occupied duplex exemption is a plus for house hackers, but it doesn't help with the insurance line item. I'm curious... with your experience managing in San Jose, are you seeing that insurance spike hit 2-4-unit properties harder than larger complexes? Trying to figure out if the pain is worst exactly at the scale where first-time investors like me are looking to buy.
