Description
23 years of property sales data from the State of Connecticut, covering transactions with a price of $2,000 or more. The Office of Policy and Management collects this information annually for each grand list year from October 1 to September 30. Records include town, property address, sale date, property type, sales price, and assessment value.
Use Cases
Analyze sales price trends by town and property type over the 23-year period.
Model property assessment values against actual sales price to evaluate assessment accuracy.
Identify commercial and industrial property sale patterns across different Connecticut municipalities.
Track annual sales volume and price fluctuations within each grand list year from October to September.
Strengths
Covers a 23-year time span from 2001 to 2023, providing long-term trend analysis.
Includes six key data fields per record: town, address, date, property type, sales price, and assessment.
Data is collected under specific Connecticut statutes (10-261a, 10-261b), ensuring a legal reporting framework.
Available in multiple machine-readable formats including CSV, JSON, RDF, and XML.
Limitations
Data completeness varies as municipalities are exempt from reporting for 12 months after a property revaluation.
The dataset only includes sales of $2,000 or more, potentially omitting very low-value transactions.
The exact row count and total data volume are unspecified, making scale assessment difficult.
