Andover Properties acquired a self-storage facility at 123 First Street in Leominster, Massachusetts, on September 10, 2026, per PR Newswire. The deal adds nearly 62,000 net rentable square feet and almost 800 units to a portfolio that already exceeds 14 million square feet across more than 175 facilities in 20 states.
The property will operate under Storage King USA, Andover's self-storage brand. President and CEO Brian Cohen framed the trade as a textbook value-add acquisition: buy a well-located facility from an independent owner, then run it through Andover's in-house operating stack.
What Did Andover Acquire in Leominster?
The Leominster facility is not a greenfield box on the urban fringe. The building dates to 1901, which makes it an adaptive reuse or multi-phase conversion asset rather than a purpose-built 2010s climate-controlled prototype.
That vintage matters for underwriting. The property mixes climate-controlled units with convenient drive-up access, a combination that serves both residential overflow storage and small-business inventory needs in Central Massachusetts. Amenities include elevator and freight lift access, loading docks, and video surveillance.
| Attribute | Detail |
|---|---|
| Address | 123 First Street, Leominster, MA |
| Net rentable SF | ~62,000 |
| Units | ~800 |
| Vintage | Built 1901 |
| Product mix | Climate-controlled + drive-up |
| Amenities | Elevator, freight lift, loading docks, video surveillance |
Leominster sits northwest of Worcester in a corridor where household growth and limited new supply support stabilized occupancy, even as national advertised rates remain down 1.6% year over year through July 2026.
Why Does Andover Keep Buying Mom-and-Pop Assets in 2026?
Andover's September 10 release restates a strategy the firm has executed all year: acquire well-located facilities from independent owners and unlock value through operational scale.
Cohen cited Leominster's market fundamentals and Andover's ability to improve performance through targeted marketing, revenue management, and Storage King USA's customer service platform. That language matches the firm's June 2026 Denver-Lakewood two-property closing, where Cohen emphasized below-replacement-cost basis in supply-constrained submarkets.
This acquisition exemplifies Andover's core investment strategy of acquiring well-located facilities from independent owners and leveraging our robust operating platform to unlock value.

The private platform model differs from REIT balance-sheet buying. Andover does not need to justify a $1.2 billion cross-border platform close like Public Storage's Canada acquisition. It needs repeatable 400-to-800-unit trades where rebranding, revenue management, and centralized marketing produce measurable NOI lift within 12 to 18 months.
Inside Self-Storage's June 2026 acquisitions roundup documented the same pattern across U-Haul, Merit Hill Capital, and regional operators. Andover's Leominster buy is another data point in a year when liquidity exists below the billion-dollar headlines.
How Does the Northeast Fit Andover's Geographic Strategy?
Andover is headquartered in New York City with offices in Miami and San Francisco. The Leominster acquisition deepens Northeast density alongside prior Massachusetts activity and the firm's broader alternative-asset portfolio.
The Northeast offers a different demand profile than the Sun Belt markets where supply headlines dominate. Yardi Matrix's August 2026 report shows improving occupancy nationally even as advertised rates fall year over year. Coastal and Northeast metros often show tighter supply pipelines than Phoenix, Orlando, or Tampa.
For Andover, the Leominster trade is a bet that Central Massachusetts household stability and limited entitled land outweigh the operational complexity of a 1901-vintage building. Elevator access and loading docks suggest commercial tenant mix potential that pure drive-up suburban boxes cannot capture.
What Does September 2026 Deal Flow Look Like Around This Trade?
September opened with institutional-scale closings at both ends of the market. Public Storage finished its Canada platform. Marcus & Millichap moved an 861-unit Wisconsin portfolio. Basis Industrial closed a $20.5 million construction loan for a 707-unit ground-up project in Arizona.
Andover's Leominster buy sits in the middle: too small for REIT earnings call headlines, too large for a single-facility mom-and-pop exit without institutional buyer interest. It confirms that private platforms with operating infrastructure still compete aggressively for regional assets while public REITs focus on joint ventures, share repurchases, and platform-scale M&A.
What Should Operators Take From the Leominster Closing?
Independent owners still have exit liquidity. Andover's release does not disclose price, but the public announcement itself signals competitive bidding for well-located Northeast assets with operational upside.
Mixed-format vintage assets trade. Not every 2026 acquisition is a 2021 Class A climate-controlled prototype. Operators with elevator service, loading docks, and drive-up options serve a tenant base that newer suburban boxes ignore.
Vertically integrated platforms win repeat deals. Andover runs property management, marketing, revenue management, and construction in-house. That integration is the pitch to sellers who want a clean exit without watching a passive buyer strip staffing and let occupancy drift.
The Numbers Worth Writing Down
- Announcement date: September 10, 2026
- Address: 123 First Street, Leominster, Massachusetts
- Units: ~800
- Net rentable square feet: ~62,000
- Vintage: 1901

- Buyer HQ: New York City (offices in Miami and San Francisco)
Operating Scale Beats One-Off Exits
Andover did not buy Leominster for a trophy address. It bought an 800-unit asset where Storage King USA's revenue management, marketing, and in-house construction can compound over a hold period measured in years, not quarters.
That is the September 2026 private-market story in one sentence: REITs chase platforms and billion-dollar closes, while vertically integrated operators keep aggregating mom-and-pop assets one well-located facility at a time. Leominster is Andover's latest proof that the playbook still clears.
