The year’s biggest apartment deal never hit the open market, yet it reshaped the 3rd quarter sales totals almost on its own.

  • Annual apartment sales volumes jumped 28.1% from 2nd quarter to $208.1 billion, the highest total since 1st quarter 2023.
  • Coastal metros added $45.9 billion, more than the entire national gain, as the AvalonBay and Equity Residential merger entered the data.
  • Deal count slipped 2.1% to 6,424, the first quarterly decline since 2nd quarter 2024.
  • Cap rates held at 5.4% for an eighth straight quarter, just 5 basis points above the 10-year Treasury yield.

One Merger Rewrites the Annual Total

According to MSCI Real Capital Analytics and referenced against the Realpage Top 150 markets, apartment sales totaled $208.1 billion in the year-ending 3rd quarter 2026. That is $45.6 billion more than the prior quarter and 39.8% above a year earlier.

Most of that jump traces back to August 17, when AvalonBay Communities and Equity Residential closed their all-stock merger to form Vivmark Residential, a REIT with roughly 184,000 apartments and an enterprise value near $70 billion. MSCI counts the combination as each company selling its portfolio to the new entity, which helped push national apartment volume in August alone to $80.5 billion.

Coastal Markets Carried the Quarter

Coastal metros in California, the Pacific Northwest, the Northeast and Washington, DC added $45.9 billion in annual volume, and their combined $109.8 billion total doubled from a year ago. Everywhere else, annual volume slipped $0.2 billion to $98 billion and deal count fell 8% in a single quarter.

Washington, DC, where the two REITs owned more than 24,000 apartments between them, shows the pattern most clearly. Annual volume there doubled to $16.1 billion, making it the top market in the country for dollar volume.

Pricing Holds as Treasury Yields Catch Up

Average price per unit rose 0.9% from 2nd quarter to $228,777, essentially flat from a year ago, and cap rates held at 5.4% for an eighth straight quarter. The pressure now is coming from the bond market.

The 10-year Treasury yield climbed to 5.35% on October 7, its highest level since 2002, according to CNBC. That leaves cap rates just 5 basis points above the 10-year, compared with about 125 basis points a year earlier, when the yield sat near 4.14%.

A Federal Reserve rate hike in September, higher oil prices tied to the Iran conflict and heavy federal borrowing have all pushed long-term rates higher. When an apartment yields about the same as a Treasury, buyers need stronger rent growth to justify current pricing, and financing no longer adds to returns.

The Five Biggest Apartment Deals of 3Q 2026

The quarter’s five largest single-asset trades ranged from $206 million to $347 million, and Arlington, VA, claimed two of them.

  1. Lynhaven, San Jose, CA, $346.5 Million. KKR paid about $544,800 per unit for the 636-unit community, completed in 2020, buying from Greystar and Goldman Sachs in late August.
  2. The Kensington, Boston, MA, $234 Million. Pontegadea, the investment firm of Inditex founder Amancio Ortega, paid roughly $614,200 per unit for the 27-story, 381-unit tower in July, the highest per-door price in the group.
  3. The Point National Landing, Arlington, VA, $211.5 Million. Pantzer Properties bought the 25-story, 440-unit tower from Kimco and CPP Investments in mid-August for about $480,700 per unit.
  4. Portofino Place, West Palm Beach, FL, $208.0 Million. Fairfield Residential paid about $256,200 per unit for the 812-unit garden community built in 2003. Cortland paid $130 million in 2016, so its exit came in 60% higher.
  5. Central Place Residential, Arlington, VA, $206.3 Million. Berkshire Group bought the 377-unit tower, completed in 2017, from JBG Smith on the first day of the quarter at about $547,100 per unit.

What to Watch

The merger stays in the annual totals until 3rd quarter 2027, so deal count and activity outside coastal markets are the better read on the market for now. If the 10-year holds above 5%, expect sellers to face more pressure to accept higher cap rates in the coming quarters.
