A 2024 UC Berkeley Haas study found that a one-standard-deviation increase in long-term-rental company market-share growth causes an additional 2.11 percentage points of annual house-price growth and 2.19 percentage points of rent growth in U.S. census tracts.
Philadelphia Fed economists estimated that the rise of institutional buyers explained 58% of the increase in real single-family house-price appreciation rates between 2006 and 2014, and 75% of the contemporaneous decline in homeownership rates.
A 2024 GAO review found that institutional investors collectively owned 170,000 to 300,000 single-family homes by 2015, rising from zero entities owning at least 1,000 homes as of late 2011.
A 2025 study across 57 cities in 15 countries found that pension-fund-driven residential-equity REIT capital inflows increase multifamily house prices while correlating with declining rents.

The Federal Reserve's first MBS purchase program, running from November 25, 2008 to March 31, 2010, purchased $1.25 trillion of agency MBS and reduced mortgage rates by an estimated 85 basis points immediately upon announcement.
Fannie Mae in August 2009 and Freddie Mac in September 2010 launched First Look programs granting owner-occupants and non-profits a 15-to-30-day exclusive bidding priority on REO homes before offering them to institutional investors.
