California's Investor-Owned Homes Crisis: A Growing Affordability Concern

Strategic Insights

— 2 min read

California's housing market has reached a boiling point, with one in five homes owned by investors, highlighting a deepening affordability crisis that shows no signs of abating. According to data from BatchData and analyzed by the Orange County Register, the state's mountain regions are particularly affected, with Sierra county boasting an astonishing 83% share of investor-owned homes. While the trend is not unique to California, it exacerbates the state's acute housing shortage, with home prices surging 50% in the past six years and an estimated 4.5 million homes short in the US.

Key Takeaways:

  • California's overall percentage of investor home ownership sits at 19%, with some mountain regions like Sierra county having 83% of their homes owned by investors.
  • Seven California counties – Sierra, Trinity, Mono, Alpine, Plumas, Modoc, and Calaveras – have seen investors own more than 50% of homes.
  • The state's most urban counties, such as Los Angeles, San Francisco, San Diego, and Orange, have lower shares of investor-owned homes, ranging from 15% to 16%.
  • Investor-owned homes account for 26.8% of all national residential property sales in the first quarter of 2025, up from the previous five-year low.
  • The doubling of mortgage rates in 2022 significantly cut homebuyer purchases, leading to investors' increased market share.
  • Omar Ocampo, a researcher at the Institute for Policy Studies, argues that "mega investors and small investors" are not reducing housing prices, but rather putting upward pressure on them.
  • California ranked second in the country by quantity of investor-owned homes, with 1.45 million, after Texas (1.66 million), and ahead of Florida (1.21 million).
  • Investors owning between one and five properties account for 90% of investor-owned homes, while those owning six to 10 properties account for another 5%.
