Fewer flat owners are jumping at the chance to sell their Housing Board unit once they can, as weak resale prices make it more worthwhile to hold on.
Two years ago, almost one in five of those who turned eligible to sell their flat - having stayed for the minimum five years - promptly did so within the year.
But last year, amid a cooling market, only 5.5 per cent who had met the minimum occupation period (MOP) did so.
Of 8,521 possible flats, 470 changed hands within a year of meeting MOP, HDB figures showed.
