Private equity and other institutional investors now hold roughly 13% of apartment units across the United States, according to real estate data compiled by CRE Daily, and one 2024 transaction shows how a single buyer can reset rent expectations for thousands of households at once: global investment firm KKR closed on 5,200 apartment units spread across 18 properties for $2.1 billion, a deal it called its largest-ever apartment acquisition.

What the deal covered

• 5,200 units across 18 multifamily properties concentrated in Coastal and Sunbelt markets
• $2.1 billion purchase price, announced in mid-2024
• Four U.S. senators formally pressed KKR on how the acquisition would affect existing tenants’ rent
• Institutional investors now hold roughly 13% of U.S. apartment units, per CRE Daily’s tracking

Senators Elizabeth Warren, Raphael Warnock, Ron Wyden and Peter Welch sent KKR a letter, later published as a joint press release, stating: “We are deeply concerned that KKR’s multi-billion dollar real estate purchase could result in even higher rents, exacerbating America’s housing crisis.” The senators noted that a KKR executive had separately described the firm as optimistic about rent growth given what the company called a structural shortage of housing.

The mechanics matter as much as the dollar figure. When one owner controls an entire complex, every lease tends to run on the same centralized rent-setting schedule and renewal notice, which means a resident who wants to negotiate is negotiating with a portfolio manager overseeing thousands of units elsewhere, not a landlord down the street. NBC News reporting on the broader institutional-landlord trend describes renewal notices arriving with a single percentage increase applied across units of similar size, with little room for individual tenants to push back before the option window closes.

The KKR letter was not an isolated inquiry. Warren’s office has separately pressed other large corporate landlords over rental practices through the Senate Banking Committee, and the original KKR letter itself tied the deal to a wider pattern, noting that private equity ownership has “disproportionately pushed people of color out of affordable single-family homes.” The same consolidation dynamic applies just as directly to apartment complexes bought and repriced in bulk: once a single firm controls every unit in a building, the tenants inside lose the one thing that used to give them any leverage at renewal time — a landlord they could actually negotiate with.

The KKR letter is not an isolated flashpoint. The Private Equity Stakeholder Project, which tracks large-scale rental acquisitions nationally, has documented a steady stream of similar bulk purchases in recent years, and lawmakers are now examining multiple firms using comparable strategies. For tenants inside buildings that change hands this way, the practical result looks the same no matter whose name is on the deed: a renewal letter that reads less like an offer than a notice, with the number already decided before it reaches the mailbox.
