The tail end of the housing bust brought a frenzy of real estate investors to the Sacramento region, including multi-billion-dollar hedge funds.
Now that the dust has settled, investors own about 80,000, or roughly one in four, detached, single-family homes in Sacramento County, according to a Bee review of parcel data from the county assessor's office.
Before the recession, investors owned about one in six homes in the county.
Investors have effectively taken over the real estate market in several economically depressed neighborhoods. In south and central Oak Park for instance, investors own about 55 percent of single-family, detached homes.
The flurry of investor activity helped raise home prices by increasing demand. Investors often refurbished homes long left vacant. But they also pushed out would-be homeowners who couldn't compete with cash buyers.

Data for Sacramento County current as of November 2013. The Bee determined which homes were owned by investors by isolating parcels where the property tax bill goes to a different address than the home itself. Data for suburbs comes from U.S. Census Bureau and covers the three-year period between 2010 and 2012.
