Why did commercial real estate sales volume spike 127% in August if individual property deals are slowing down?

August commercial real estate total sales volume reached $107B, a 127% year-over-year increase, driven by $70B in M&A-type deals, according to MSCI. Excluding M&A, single-asset sales volume fell roughly 21% compared to the prior year. The AvalonBay Communities and Equity Residential merger, creating Vivmark Residential with an enterprise value around $70B, was the primary driver.

Commercial real estate sales volume reached $107 billion in August, up 127% from the prior year, according to MSCI. Merger and acquisition activity accounted for $70 billion of that total. Excluding M&A, sales fell roughly 21% compared to August last year.

M&A deal volume set a record for a single month in August, MSCI analysts wrote. The data reflects a highly liquid market, but one where the expansion of deal volume is slowing, the analysts said.

The merger of AvalonBay Communities and Equity Residential to create a new REIT called Vivmark Residential with an enterprise value around $70 billion was the main driver of August deal volume. The combination lifted multifamily transaction volume for the month by 402% compared to last year.

Industrial asset sales volume rose 14% year-over-year to $11.5 billion, and senior housing sales climbed 8%. Every other asset class saw volume slip. Data centers recorded no asset sales in August. Hotel sales fell 45%. Office, retail and development site sales volumes were all down compared to the prior year.

Prices barely moved in August, with the RCA CPPI U.S. National All-Property Index up 0.1% from the prior year. The average capitalization rate across all transactions in August was 6.01%, down 80 basis points from the prior month.

Rising interest rates and the shifting capital markets environment were unlikely to have scuttled many deals in August but could put pressure on activity in the months ahead, analysts at JPMorgan Chase wrote in a note to investors. The leg up in interest rates on both the long and short end of the curve occurred later in the quarter, and there was likely little impact on deals in motion from a transaction timing point of view, the analysts wrote.

Investors are adjusting to expectations that interest rates will remain elevated, but current costs have not derailed deals so much as they have slowed down decision-making, the analysts wrote. The multifamily sector, where capitalization rates are already relatively low, faces the most risk that elevated debt service costs could scuttle deals, they said. Despite the moderation in activity, year-to-date sales volume is up 53% from last year at $483 billion, driven by a 221% increase in portfolio and entity-level deals. Single-asset sales volume is up 12% through August compared to last year.

The Deployment Angle

Family Office Real Estate Daily Desk · our analysis, not the source's

The 80-basis-point compression in average cap rates from July to August—from 6.81% to 6.01%—signals that the megadeals closed at tighter pricing than the single-asset market would support. Family offices evaluating co-investment alongside sponsors in portfolio or entity-level transactions should discount headline pricing by at least that spread when modeling standalone acquisitions. The divergence means a platform recap priced at a 6% cap may imply 6.8% or higher for the underlying assets if sold individually.

Multifamily remains the sector most vulnerable to financing risk. If cap rates are already relatively low and debt service costs rise further, sponsors may struggle to maintain agreed equity returns without repricing or walking from deposits. Family offices writing co-GP cheques into multifamily deals should insist on financing contingencies that survive the due diligence period, or structure preferred equity with a lookback right if the sponsor cannot close on the original debt assumption. The 402% year-over-year surge in multifamily volume came entirely from the AvalonBay-Equity Residential merger, not from organic buyer appetite.

Industrial's 14% volume increase and senior housing's 8% gain suggest those sectors still clear at current pricing. Family offices with dry powder should tilt toward industrial separate accounts or programmatic joint ventures with established operators, where the bid-ask spread has narrowed enough to sustain deal flow. Avoid opportunistic hotel or data center exposure for now—hotel sales fell 45% and data centers recorded zero transactions in August, indicating that sellers and buyers remain far apart on terminal value assumptions in those asset classes.
