Andover Properties
The Firm
Andover Properties is a private real estate firm founded in 2003 by Brian and William Cohen and run from New York, with offices in Miami and San Francisco. It invests across alternative real estate, including manufactured housing, RV parks, small-bay industrial, and car washes, but its largest platform is self-storage, operated under the Storage King brand.
The self-storage portfolio spans more than 14 million net rentable square feet across over 170 facilities in twenty states. Andover grows it by acquiring individual facilities and small portfolios from independent owners, folding them into Storage King with its own management and capital. It builds regional density: in North Carolina alone it reached its seventeenth location in 2026.
For a searcher looking at a single storage facility, Andover is the kind of buyer already active in the same local markets, and a plausible eventual exit. Its recent purchases, from a 487-unit site in Garner to another in nearby Cary, are the owner-operated facilities an independent buyer would also bid on, so its density in a metro signals how much competition to expect there.
What It Buys
New York, New York. A New York self-storage owner-operator with more than 170 facilities across twenty states under the Storage King brand, growing by buying independent facilities from their owners and rebranding them.
