Boston Condo Market Update — September 2026

Boston Real Estate Market Snapshot

The September 2026 Boston condo market is giving buyers and sellers something we have not seen consistently in recent years: more choice, more negotiation, and a much greater premium on accurate pricing.

Based on September 1–30, 2026 MLS PIN data covering Back Bay, Beacon Hill, the North End, Seaport District, South Boston and its sub-neighborhoods, the South End, and Waterfront, the market recorded the following results:

Average Sale Price: $1,715,110
Listings Sold: 97
Average Days to Offer: 46 days
List-to-Sale Price Ratio: 97%
Under Agreement/Pending Listings: 77
Price Changed Listings: 142

Those 142 listings underwent 155 total price changes, with an average cumulative reduction of 5.23%, or approximately $83,818. This is an important signal for Boston sellers: buyers remain active, but they are increasingly sensitive to properties that enter the market above perceived value.

What Is Happening in the Boston Real Estate Market Right Now?

Boston entered the fall market with more inventory and a slower pace than a year earlier. September citywide data show active inventory up 16.1% year over year while homes took a median 43 days to sell, six days longer than a year ago. At the same time, new listings declined 1.9%, suggesting that the increase in available inventory is partly the result of properties taking longer to sell rather than simply a surge of new sellers.

Higher borrowing costs are also influencing buyer behavior. Mortgage rates moved above 7% during September, reducing purchasing power and contributing to greater price sensitivity nationally. In Boston, this environment is creating a more selective buyer pool: well-positioned properties can still attract strong interest, while overpriced or compromised properties are more likely to remain available and require adjustments.

Highest-Performing Boston Neighborhoods

Performance varies considerably by neighborhood and price point.

South Boston continues to stand out for transaction activity. Through August, 282 condos had sold in 2026, with median price per square foot reaching $859, up 2.9% from the comparable 2025 period. Properties were taking longer to sell, however, with median market time increasing to 39 days and sales averaging 97.4% of asking price.

Beacon Hill remains a strong luxury market. September data put its median sold price at approximately $1.23 million, up 12.2% year over year, although longer marketing times demonstrate that buyers at higher price points continue to be selective. Realtor

The South End remains one of Boston's most sought-after condo neighborhoods, but September produced a more balanced environment. Its median sold price was approximately $1.05 million and properties sold at roughly 99% of asking price. Realtor

Seaport presents a different opportunity. It remains one of Boston's most expensive condo markets, but buyers currently have substantially more negotiating leverage. Through August, Seaport's median price per square foot was $1,603, down 3.5% year over year, while available supply was estimated at 8.5 months.

Boston Condo Market Overview

Condominiums are central to Boston's urban housing market, particularly in neighborhoods such as Back Bay, Beacon Hill, South Boston, South End, Seaport and Waterfront. September's MLS data show a market that remains valuable but has become increasingly segmented.

The 97 condos sold during September achieved an average sale price of $1,715,110, compared with an average final list price of $1,766,617. The resulting 97% sale-to-list ratio demonstrates that buyers are negotiating, but desirable properties are still retaining most of their asking value.

The difference between initial asking prices and eventual sale prices is even more revealing. September's sold properties had an average original asking price of $1,806,272 and ultimately sold at approximately 95% of original asking price.

Key Boston Condo Market Trends

The defining trend this fall is market segmentation. There is no single Boston condo market. Neighborhood, condition, price point, building quality, outdoor space, parking, amenities and initial pricing can dramatically affect buyer response.

Inventory is giving buyers more alternatives, particularly at higher price points. At the same time, Boston's September MLS statistics show that correctly positioned properties continue to transact: 97 condos closed and another 77 were pending or under agreement during the reporting period.

Price adjustments have also become an important part of the market. With 142 listings recording price changes during September, sellers should view initial pricing as a critical component of their marketing strategy rather than simply a starting point for negotiation.

What Boston Home Buyers Should Expect Right Now

Boston condo buyers have more negotiating leverage than they did in an ultra-competitive market, but opportunities vary sharply by property.

Buyers should pay particular attention to days on market, previous price reductions, comparable closed sales, condo fees, reserves, upcoming assessments and the financial health of the condominium association. Properties that have accumulated market time or undergone price reductions may provide opportunities to negotiate price or terms.

However, buyers should not assume that every property is negotiable. Well-priced condos in desirable locations can still generate strong competition. A neighborhood-specific comparable-market analysis is therefore considerably more useful than relying on Boston-wide averages.

What Boston Home Sellers Should Expect Right Now

For sellers, September's numbers deliver a clear message: pricing accurately from the beginning matters.

Boston condos sold for an average 97% of their final asking prices during September, but the average sale-to-original-price ratio was only 95%. In addition, 142 properties recorded price changes. Together, those figures suggest that sellers who begin too aggressively may ultimately need to reposition their properties before finding a buyer.

Preparation and presentation are equally important. Buyers have more properties to compare, making professional photography, staging, condition, marketing strategy and positioning against competing inventory increasingly consequential.

For homeowners considering selling a condo in Boston, the most useful question is not simply, "What is the Boston market doing?" It is, "What are buyers doing right now for properties like mine, in my neighborhood and price range?"

Working with an experienced Boston real estate agent who understands neighborhood-level inventory, recent comparable sales, buyer behavior and current competition can help determine the pricing and marketing strategy most appropriate for a specific property.
