South Coast Real Estate Market Update: A Look at the August 2026 Numbers

As we transition out of the summer months, the South Coast real estate market continues to be defined by nuanced, localized activity. At the Bernadette Kelly Group, we know that broad headlines rarely capture what is actually happening in your specific neighborhood. Our August 2026 data reveals a market where inventory constraints heavily influence monthly averages, making it more important than ever to look at the context behind the numbers.

Key Takeaways Our overarching theme for August is “inventory-driven averages.” In our higher-volume towns, we are seeing steady activity and value appreciation. However, in our smaller coastal communities, extremely low transaction volumes mean that a single sale can dramatically skew the monthly percentages. Understanding this market composition is crucial for both buyers planning their offers and sellers pricing their homes for the fall.

A Deeper Dive: Town by Town

• Marion: August saw incredibly limited inventory turnover in Marion, with only 1 closed sale for the month, representing an 80% decrease in volume year-over-year. Because of this limited data set, the $1,250,000 average price and the 22 days on market are reflective of this single property’s specific market journey, rather than a definitive shift in overall town property values.
• Mattapoisett: We observed solid, decisive buyer activity in Mattapoisett. With 8 closed sales (matching last year’s volume), the average sale price reached $840,375—a 21% year-over-year increase. Notably, homes spent significantly less time waiting for an offer; the average Days on Market dropped by 61% to just 44 days, and sellers received an average of 96% of their list price.
• Rochester: Rochester recorded 5 closed sales in August. You may notice a striking 629% year-over-year increase in Days on Market, bringing the average to 124 days. With such low transaction volume, this is a clear example of market composition at work; the average was skewed by a small number of listings that required longer marketing periods, rather than a sudden freeze in buyer demand. The average price here sits at $778,180.
• Wareham: Wareham provided the highest volume of data this month with 24 closed sales, a slight 4% increase over last year. This volume allows for a reliable view of market trends, highlighting a steady 18% increase in average price to $667,246. Sellers in Wareham are also capturing excellent value, securing 98% of their list prices on average.

What It Means for You If you are tracking the value of your home, remember that a single month’s data in a low-volume market requires an expert eye to interpret accurately. A sudden drop or spike in a town’s average price or market time often reflects the specific mix of homes that happened to close that month—not necessarily the value of your own property. Navigating this environment requires a tailored, logical strategy rather than relying on generalized data points.
