Two of the largest apartment real estate investment trusts in the U.S. are merging in a $71 billion deal that will create the country’s biggest multifamily landlord.
The largest REIT merger in history
Equity Residential and AvalonBay Communities announced the all-stock merger on May 21, forming a new company called Vivmark Residential. The combined entity will own more than 180,000 rental apartments across over 600 communities, primarily in coastal cities like New York, San Francisco, Boston, and Washington, D.C. Another 10,800 units are under construction, with half designated as affordable or mixed-income housing.
The transaction surpasses the 2022 merger of Prologis and Duke Realty, valued at $26 billion, making it the largest public REIT merger ever. Equity Residential owns 85,000 apartments and holds $20.5 billion in assets, while AvalonBay manages 98,000 apartments with a $25 billion market capitalization. Both operate in nearly identical markets, with analysts noting a 95% overlap.
Allan Swaringen, president and CEO of JLL Income Property Trust, called it a “true merger of equals.” “These are the two biggest gorillas in the multifamily marketplace who decided to come together,” he said.
Matt Frankel, a stock market analyst at the Motley Fool, compared the deal to a hypothetical merger between Visa and Mastercard. “They’re businesses of the same size and specialize in the same markets and price points,” he said. “The combination just makes a whole lot of sense.”

The merger arrives after years of low interest rates allowed both companies to expand easily. Before and immediately after the COVID-19 pandemic, cheap capital enabled growth without urgency. Higher borrowing costs and moderating rents have since pushed them to seek efficiencies.
The firms expect $175 million in cost savings within 18 months of closing but did not respond to requests for comment.
The deal reflects broader consolidation in real estate. While Vivmark will control less than 1% of U.S. housing, its dominance in key coastal cities could draw regulatory scrutiny. In New York and San Francisco, the new company may control over 30% of apartment supply in certain submarkets, potentially triggering antitrust reviews.
Experts say the merger is unlikely to face major opposition. The Hart-Scott-Rodino Antitrust Improvements Act includes exemptions for direct real estate asset acquisitions, and regulators have historically been lenient with multifamily deals. However, the current political focus on housing affordability could complicate matters.
Cultural and operational challenges
Equity Residential and AvalonBay have distinct histories. Equity Residential, founded in the 1960s by the late Sam Zell, built its reputation on acquiring existing properties in high-barrier markets. AvalonBay, formed in 1998 from a merger between Bay Apartment Communities and Avalon Properties, focuses on developing luxury, Class A properties.

Vince Norris, executive managing director of multifamily investment sales at Northmarq, described the differences. “Avalon is an upper middle-class operator known for client services and a larger development pipeline,” he said. “Equity Residential preferred buying existing communities in markets with high entry barriers.”
Merging these approaches will not be simple. The companies have operated independently for decades, and combining their corporate structures—including dual headquarters and a split board—could create friction. Layoffs are expected to eliminate redundancies, which may further strain morale.
David Auerbach, chief investment officer at Hoya Capital, said the merger will improve operating density in core markets while broadening the growth runway across newer expansion regions. “The only thing I see working against them is the loss of human capital. There will unfortunately be some expandable people when it comes to this,” he said.
Brad Dillman, founder of Florey Street Advisors, noted their heavy exposure to coastal markets leaves them vulnerable to demand shifts. “They overlap in 95% of their geographies, and the industry has focused on generating returns through operational improvements, usually achieved through local scale,” he said. “This merger increases concentration in coastal areas, and they may need to shift focus to the Sun Belt as it grows.”
The merger’s immediate impact on renters remains uncertain. Analysts say cost efficiencies could help stabilize or lower rents in some markets, but the combined company’s market power may work against that.

Investors have reacted cautiously. Since the announcement, Equity Residential’s stock rose about 2.7%, while AvalonBay’s increased by 2.5%, matching broader sector performance. “No investors have treated this as a must-buy opportunity,” said Swaringen.
The merger is expected to close later this year, pending regulatory approval. If successful, it could change the rental market, though risks—including regulatory hurdles, cultural clashes, and pressure to deliver faster earnings growth—remain significant.
Alexander Goldfarb, managing director at Piper Sandler, emphasized that scale alone is not enough. “The merger must drive faster earnings growth, and that remains to be seen,” he said.
Auerbach also warned of potential regulatory hurdles. “The immediate reaction is that this will be held up by the government. The government won’t let these two get together,” he said.
