Vivmark Residential Pays $742M for Bay Area Apartments

Vivmark Residential, the real estate investment trust formed by the merger of Equity Residential and AvalonBay Communities, closed its first acquisition since the deal completed, paying $741.8 million for seven Northern California apartment communities totaling 1,843 units. That works out to roughly $402,600 per unit, a figure institutional sellers and buyers across the multifamily market will now treat as a live comp set by the country’s newly largest apartment landlord.

Why it matters

Every developer underwriting a Bay Area multifamily exit, or pricing a bid against Vivmark anywhere else, now has a fresh data point from the company itself. The portfolio spans Campbell, Mountain View, Fremont, Dublin and Union City, all Silicon Valley and East Bay submarkets where AvalonBay already operated under its Avalon and eaves brands. Records checked against AvalonBay’s own SEC filings show most of these communities, including Avalon Campbell and eaves Union City, were already wholly owned and consolidated on the company’s balance sheet as of December 31, 2025, before the merger closed on August 17. That makes this less a new market entry and more a repricing and recapitalization of assets Vivmark already controlled, a distinction that matters for anyone reading it as fresh coastal demand. We covered the merger’s formation on August 10.

The numbers

The seven communities total 1,843 units for $741.8 million. Avalon Campbell in Campbell sold for $147.3 million on 348 units, the largest single property in the group. Analyst Brad Dillman of Florey Street Advisors said the combined company “decided to double down on the coasts.” AvalonBay’s FY2025 10-K carried Avalon Campbell’s gross investment basis at roughly $77.7 million, built in 1995, underscoring how much value the national multifamily market has added to older Bay Area stock over three decades.

What’s next

Vivmark has not disclosed the seller or financing structure for the deal, and no additional 8-K describing the transaction had appeared on EDGAR as of this writing. Developers competing for institutional multifamily capital should expect Vivmark to keep pricing off its own back book as it integrates two of the largest apartment platforms in the country, rather than chase entirely new geographies in its first months as a combined REIT.
