As announced on 9 Dec 2014, HDB will adopt the Stratified Hedonic Regression method to compute the Resale Price Index (RPI), starting from the flash estimate of the 4th Quarter 2014.
2The Stratified Hedonic Regression method will control for variations in flat attributes of the resale flats transacted, thus better reflecting price changes over time. This allows the index to continue serving its purpose of providing timely and reliable information on resale market movements.
3HDB’s flash estimate of the 4th Quarter 2014 RPI using the revised method is 137.1, a decline of 1.4% over 3rd Quarter 2014 (see Annexes A1 and A2 
(PDF 21KB)). The previous RPI from 1Q1990 to 3Q2014 has been re-scaled to the new base period of 1Q2009, but the quarterly percentage changes remain unchanged.

4The RPI provides an indication of the general price trend of resale HDB flats. Prospective flat buyers and sellers may refer to the transacted prices of individual flats (by block and flat type) which are available in the HDB InfoWEB (online enquiry) for their price negotiation.
5The RPI for the full quarter and more detailed public housing data for 4th Quarter 2014 will be released on 23 January 2015.
