Boston Realty Advisors markets 16-property Beacon Hill and Back Bay portfolio

Boston Realty Advisors has been retained to sell Sentry XVI, a 130-unit portfolio of 16 separately deeded residential properties in Beacon Hill and Back Bay. The offering puts one of Boston’s rare large-scale neighborhood collections on the market, with appeal for buyers seeking immediate scale near Mass General Hospital and downtown.

Why it matters: - Sentry XVI gives buyers a rare chance to acquire 16 Boston multifamily buildings in one transaction. - The portfolio sits in two of the city’s most supply-constrained neighborhoods, where assets often trade one building at a time. - The properties are near major demand drivers, including Massachusetts General Hospital, the Financial District, and public transit.

What happened: - Boston Realty Advisors was retained as exclusive advisor for the sale of Sentry XVI. - Sentry XVI is a 130-unit multifamily portfolio made up of 16 separately deeded residential properties. - The properties are in Beacon Hill and Back Bay. - Fifteen buildings are in the Beacon Hill Historic District. - One property is 503 Beacon St. in Back Bay.

The details: - The Beacon Hill buildings are concentrated along Myrtle, Joy, Temple, Phillips and Anderson streets. - The portfolio includes buildings with 3 to 20 units each. - The properties were built between 1880 and 1920. - Studios and one-bedroom units make up 71% of the portfolio. - Boston Realty Advisors said the collection would be difficult to assemble through separate acquisitions. - Jason S. Weissman, founder and senior partner of Boston Realty Advisors, said the firm has never seen a Beacon Hill portfolio of this scale. - Kevin Benzinger, managing director at Boston Realty Advisors, said the portfolio offers potential buyers multiple business plans, including long-term hold or adaptive reuse. - The marketing team includes Weissman, Benzinger, Senior Associate Daniel Alper and Associate Dylan Steinberg. - Managing Director Jonathan Schneider is advising on debt financing. - The portfolio borders Massachusetts General Hospital and the Mass General Brigham campus. - Mass General Brigham is building a two-tower, $1.8 billion adjacent expansion. - The properties are within walking distance of the Financial District, Charles Street, Boston Common and the Charles River Esplanade. - The portfolio is one Red Line stop from Kendall Square via the Charles/MGH station. - The Sentry XVI name comes from its 16 addresses and Beacon Hill’s original name, Sentry Hill.

Between the lines: - Boston’s top neighborhoods remain fragmented ownership markets, which makes bundled offerings like Sentry XVI unusual. - The proximity to Massachusetts General Hospital and downtown Boston broadens the buyer pool beyond traditional multifamily investors. - Adaptive reuse interest suggests the portfolio could attract buyers with different operating or redevelopment strategies, not just long-term landlords.

What’s next: - Boston Realty Advisors will market the portfolio to prospective buyers. - The sale is expected to draw attention from investors looking for scale in a high-barrier Boston submarket. - Any buyer will inherit a portfolio positioned near major employment, medical and transit hubs.
