General Election might be over but the real implication has just begun. Will HDB flats located in opposition-held wards stand to lose? Hypothesis testing between two means at a 95% confidence level shows there is insufficient evidence of price difference for HDB flats between PAP-held and opposition-held wards .
Take Potong Pasir, for example. Housing prices of HDB flats sold in 2010, when the ward was still held by opposition Singapore People’s Party, were found to be comparable.

In status quo, the outcome of the general election may not have a significant impact on HDB prices in the constituency.

In terms of price upside, the average transacted price for 4- and 5-room flats in the previously opposition-held Aljunied GRC ward surged by 43% and 45% between 2009 and 2013 at the trough and peak of the property cycle, according to our study on a basket of HDB flats located along Ang Mo Kio Avenue 3. Similarly, four and five-room flats along from PAP-held Ang Mo Kio GRC increased comparably in the same period by 39% to...
