The value of a luxury apartment in Dazhi has dropped by half its original price amid the slipping property value of other buildings and apartments in greater Taipei. According to a Taiwan Realty statement released Wednesday, a top-of-the-market Dazhi luxury apartment sold recently for NT$1.445 million per ping last December, whereas it sold for 50.28 percent more, at NT$2.906 million, at its peak.
