In 2025, the average and median condo sale prices in the Boston area generally fell or remained flat, marking a shift toward a more balanced market after years of rapid growth.

Market Summary for 2025

Greater Boston: The median price for condominiums fell by 0.9% year-over-year through September 2025, settling at approximately $620,000. This followed four consecutive months of year-over-year declines during the summer.
City of Boston: Citywide pricing showed high volatility by neighborhood. While some reports noted a modest 3% increase in average sale price to roughly $1.09 million by fall, other key metrics such as price per square foot were down citywide in the second quarter.
Inventory Impact: A significant rise in inventory—up roughly 26.3% for condos—gave buyers more negotiating power and led to roughly 30% of listings in Boston seeing price drops.

Neighborhood Performance (Median Prices)

Neighborhoods experienced “bifurcated” results, with luxury areas softening while affordable entry points remained competitive.

Neighborhood	2025 Median Price (Approx.)	Trend vs. 2024
Midtown	$2,387,500	Cooling / Higher Days on Market
Seaport District	$1,799,500	Significant Decline (-24%) in some quarters
Back Bay	$1,455,500	Down ~5%
South Boston	$870,000–$905,000	Active / Holding steady
Jamaica Plain	$708,500	Moderate growth/Fast sales
Dorchester	$520,000–$615,000	Strong demand for affordable units

Key Takeaway for Buyers and Sellers

Buyers: You have significantly more leverage than in previous years due to increased inventory and longer “days on market” (averaging 38 days vs. 34 in 2024).
Sellers: Pricing accurately is now critical, as roughly half of all Boston homes sold below asking price in certain months of 2025.
