Cambridge Median Residential Sales Prices by Property Type

Median sales prices for condominiums, three-family, two-family, and single-family homes are derived from arms-length transaction records at the Middlesex South Registry of Deeds. Cambridge Community Development Department staff analyze these records to filter for unrelated-party sales, which are considered the best indicator of true market value. The dataset was last updated in November 2025.

Use Cases

• Modeling the relationship between property type (Single Family, Condominium) and price over Year.
• Analyzing price divergence between multi-family (Two Family, Three Family) and single-family housing markets.
• Forecasting future median prices for Condominium or Single Family units using historical Year trends.

Strengths

• Prices are calculated specifically from arms-length sales to reflect true market value.
• Data covers four distinct residential property types (Condominium, Three Family, Two Family, Single Family).

Limitations

• The exact number of sales transactions and row count is unknown.
• Geographic coverage is limited to properties recorded at the Middlesex South Registry of Deeds.
