Known for its rows of meticulously planned—and preserved—Victorian brownstones, the streets of Upper Back Bay offer some of the finest examples of 19th-century urban planning in the country. This fashionable, upscale neighborhood offers a seamless marriage of residential charm and commercial appeal, with abundant dining and shopping options within walking distance of its neighborhood streets.

Upper Back Bay had the most compelling year of them all. Sales volume surged from $165M in 2024 to $224M in 2025, a striking increase that reflects both heightened buyer interest and improved transaction velocity. That growth was paired with a meaningful jump in sales quantity, rising from 39 to 48 transactions year over year. In many ways, Upper Back Bay emerged as the neighborhood’s
quiet momentum play, offering scale, architectural gravitas, and value relative to its Lower Back Bay counterpart, all while capturing a growing share of buyer attention.

On the ground, agents are constantly seeking off market opportunities for clients. Yet in practice, these deals remain relatively rare. Out of 133 Back Bay luxury sales, just 24 traded off market & only 7 of those were identified in Upper Back Bay. When they do surface, a well sourced off market opportunity can create a more seamless buying experience by removing the pressure of open market competition.

The highest priced off market sale this year occurred in Upper Back Bay and was handled by Columbus and Over Group’s very own Kerry D’Ambroise, closing at an impressive $11,750,000. While this marked the top off market achievement, it was not the highest priced transaction in the sub neighborhood overall. That distinction belongs to 410 Beacon Street.

Although 410 Beacon Street sold for more, it represents a fundamentally different product. Still a single family home, it is nearly double the size of 285 Marlborough at 10,255 square feet versus 4,485 square feet. Despite the larger scale, it traded for $1,150 less per square foot than 285 Marlborough, underscoring the nuance behind headline pricing.

And while Upper Back Bay continues to trail Lower Back Bay and the High Spine on a price per square foot basis, it is worth noting that it matched them in one critical measure. The number of sales above $10,000,000 was the same – 6 per sub-neighborhood. Prestige & premium, clearly, are not lost on Upper Back Bay.
