Choose your depth. The data doesn't change — just the explanation.
When you try to buy a house, you might be competing against a giant company with billions of dollars that can pay all cash, no inspection, above asking price. In some cities, these companies were buying 1 in 4 houses for sale. When big companies own most of the homes, they can charge whatever rent they want — because there's nowhere else to go.
Institutional investors (REITs, private equity, hedge funds) used near-zero interest rates in 2020-2021 to build massive portfolios of single-family rentals. Invitation Homes (Blackstone spinoff) owns 90,000+ homes. AMH (American Homes for Rent) owns 58,000+. In markets like Atlanta and Phoenix, investors bought 40%+ of available homes at peak. All-cash offers eliminate first-time buyers who need mortgage contingencies. The result: rising home prices, rising rents, and declining homeownership rates in the most affected markets.
CoreLogic Q3 2021 data: institutional investors (>10 properties) purchased 18.4% of homes nationally; including mid-size investors (3-9 properties) brings total investor share to 24%. Market concentration: HHI analysis by MSA shows Atlanta (HHI 1,800+) and Phoenix (HHI 2,100+) in "highly concentrated" territory. Drago et al. (2023) NBER: 10% increase in institutional ownership → 4.2% rent increase in same zip code. Antitrust concern: DOJ/FTC opened inquiry 2022, no action to date. SFR-REIT dividend structure creates structural incentive to maximize rents; REIT tax treatment subsidizes concentration. RealPage algorithmic pricing investigation (DOJ 2024): coordinates rent increases across 4M+ units.

The Market Concentration Machine
When institutional capital can pay all-cash at scale, individual buyers can't compete. The result is a transfer of homeownership from families to corporations.

The RealPage Cartel
In 2024, the DOJ sued RealPage — software used by 4 million+ rental units — for algorithmic price coordination. Landlords who use RealPage's "YieldStar" system collectively share occupancy and pricing data, effectively coordinating rents in violation of antitrust law. This is how Wall Street controls rent at scale: not just through ownership, but through technology that turns competing landlords into de facto price-fixers.
