Connecticut House Price Index Based on Repeat Mortgage Transactions

Connecticut's house price index measures average price changes in repeat sales or refinancings on single-family properties. The index uses a weighted, repeat-sales statistical technique on mortgage transaction data from Fannie Mae and Freddie Mac, extending back to January 1975.

Use Cases

• Model house price trends in Connecticut using the repeat-sales index methodology.
• Analyze correlations between the state-level house price index and broader economic indicators.
• Benchmark property value fluctuations in Connecticut against other geographic levels available in the FHFA HPI collection.

Strengths

• Index methodology is fully transparent and based on a weighted, repeat-sales technique.
• Data extends back to January 1975, providing long-term historical coverage.
• Derived from a broad sample of mortgage transactions purchased or securitized by Fannie Mae or Freddie Mac.

Limitations

• Limited to single-family properties with mortgages backed by Fannie Mae or Freddie Mac, excluding other transaction types.
• Sample data and specific row counts for Connecticut are unavailable, limiting granular analysis.
• Data is aggregated to an index, lacking underlying transaction-level details like sale price or property characteristics.
