* Home price changes are calculated by HKU Real Estate Lab using the the repeat-sales method.  Further information can be found in Appendix B of the paper Policy Responses to an Overheated Housing Market: Credit Tightening versus Transaction Taxes. The district-based repeat-sales indices have been utilized in various studies, including those on Covid-19 vs SARS, developers’ market power, and urban renewal. For monthly price indices across the entire city, please refer to HKU-REIS.
