Boston Condos for Sale

Can I do my own Boston condo for sale comps?

• Real Estate Listing Sites: Platforms like Zillow and Realtor.com allow you to filter for “Recently Sold” properties.
• Public Records: The City of Boston Assessing Department provides official property data and sale prices.
• Market Dashboards: The Greater Boston Association of REALTORS® (GBAR) offers interactive dashboards for tracking historical trends in the Boston condo market. 
   

• Location: Limit your search to within 0.25 to 0.5 miles of your condo. In dense Boston neighborhoods like Beacon Hill or the North End, even a few blocks can significantly change the value.
• Time Frame: Only use sales from the last 3 to 6 months to reflect current market conditions.
• Property Type: Only compare condos to other condos. Comparing a condo to a single-family home or townhouse will yield misleading results.
• Size & Specs: Stay within 20% of the square footage (or roughly 300 sq. ft.) and match the bedroom and bathroom counts. 
   

• Parking: In many Boston neighborhoods, a dedicated parking spot can add tens of thousands of dollars to the value.
• Outdoor Space: Private decks, patios, or roof rights are high-value drivers in the city.
• Building Amenities: Factor in whether the comp is in a “high-rise” with a concierge and gym versus a “walk-up” brownstone.
• Condition: Adjust for recent renovations (e.g., a new chef’s kitchen) versus units with outdated systems or finishes. 
   

1. Find 3 to 5 highly similar, recently sold properties.
2. Calculate the Price per Square Foot for each by dividing the sale price by the living area.
3. Average those figures and multiply by your condo’s square footage to find a baseline market value.
