Tech Buyers Only Small Portion of San Francisco’s Cash Transactions.

With so much attention focused on the billion-dollar Bay Area tech company valuations and San Francisco rents and home prices that have escalated to all-time highs, we decided to build a profile of the most affluent home buyers—those who are paying all cash. 323 cash transactions were analyzed from February to June this year, with some very surprising findings.

Diversified Buyer Intent
66% of the cash buyers purchased a primary residence, while 31% purchased long-term investments and 3% purchased homes to flip.
Tech Buyers a Minority
The profile was far less international and tech industry than expected.

  • 6% international buyers. Only 18 buyers came from overseas, and only 8 (2%) of those were from China
  • 12% tech buyers. Only 40 of the 323 buyers came from the tech industry, and 24 of those 40 purchased in the City of San Francisco (28% of the all-cash activity in the City).
  • 42% white collar professionals. Investment bankers, consultants, and other white collar professionals purchased 136 homes.
  • 40% other buyers. Retirees, athletes, artists, and students with family money bought 129 of the homes. Retirees were the largest group.

More on the Tech Buyer
Not surprisingly, the tech buyer was geographically concentrated. Of the all-cash transactions in each market, tech buyers made up:

  • 33% of the Silicon Valley transactions
  • 27% of the San Francisco transactions
  • 10% of the Marin County transactions
  • Small percentages in Alameda, Contra Costa, Sonoma, and Napa Counties

Long-Term Investor Profile
Exactly 110 purchases by investors composed 34% of the activity and was split as follows:

  • 3% to flippers. Flippers purchased 10 of the 323 homes.
  • 7% investors to rent. 24 of the 323 transactions were completed by investors who intended to rent it out. This group included no international buyers and was all affluent domestic individuals.
  • 24% investors to hold. Exactly 76 of the 323 all-cash transactions were completed by investors who intend to use the property as a second home, with the invest-to-hold pool split as follows:
    • 2% overseas: 7 overseas buyers including 4 from China
    • 2% tech: 7 buyers from the tech industry bought vacation homes
    • 10% domestic professionals: 33 white collar professionals
    • 10% other domestic investors: 29 other investors

Primary Resident Profile
The 213 primary residents who paid all cash for their house had a very similar distribution as the investor profile, with a slightly higher likelihood of being in the tech industry. The primary resident profile is as follows:

  • 5% international
  • 15% tech
  • 42% white collar professional
  • 38% other buyers

The Venture Capital Impact Is Still Quite Large
Following the dot-com crash of 2000, San Francisco and San Jose apartment rents fell 34% and 41%, respectively, and we think another decline this time around is inevitable. One of the best leading indicators we’ve come across in trying to identify inflection points in Bay Area apartment rents is venture capital (VC) funding patterns. As seen in the chart below, the average VC deal size for Silicon Valley / Bay Area-based companies rose from $4.9 million in 1997 to a peak of roughly $17 million in 2000, equating to a 243% increase. In addition, apartment rents in San Francisco and San Jose increased a staggering 52% and 60%, respectively. Over the next three years, VC funding to local companies plummeted in lockstep with apartment rents. Fast forwarding to the current tech sector upswing, the relationship between VC funding and apartment rents is once again presenting itself clear as day.

After bottoming in 2010 at $6.9 million, the average VC deal size for Silicon Valley / Bay Area-based companies has since jumped to $23.5 million, equating to a 240% increase (almost on par with the 243% run-up of the last tech upswing in 1997–2000). During this time span apartment rents in both San Francisco and San Jose have shot up a staggering 71%. At $3,200 and $2,800, rents in San Francisco and San Jose have respectively eclipsed prior dot-com bubble peaks of roughly $2,300 by a double-digit margin.


In conclusion, the San Francisco Bay Area is on our watch list for a correction. It is a strong belief that San Francisco has become a permanently more expensive place to live and should be one of the most expensive places to live in the world, the recent increases in home prices and rents have also been fueled by speculation.

Americans who do not work in the tech industry are purchasing approximately 82% of the all-cash homes in the San Francisco Bay Area. Approximately 34% of the all-cash buyers are purchasing as an investment. The tech industry represents as much as 33% of the all-cash buyers in Silicon Valley and 27% in San Francisco, but much less elsewhere. International buyers are only 6% of the activity. Affluent older buyers, often for investment reasons, have identified San Francisco as a place they want to own or live and have driven up prices dramatically.
