Sentinel Buys 2 DC-Area Luxury Properties
The suburban properties total 797 units.

New York-based Sentinel Real Estate has expanded its multifamily holdings in the Mid-Atlantic region with the acquisition of two luxury apartment communities totaling nearly 800 units in the greater Washington, D.C., suburbs. The properties, purchased in separate deals, are located in Gaithersburg, Md., and Tysons Corner, Va.
The transactions align with the real estate investment management firm’s strategy of investing in well-located and highly amenitized properties in areas with strong economic and population growth fundamentals. The communities, built between 2022 and 2023, will give the company immediate scale and penetration into the high-barrier-to-entry D.C. suburbs.
