As long as investment costs are low (with small down payments and low interest rates) and expected benefits are high (with high rates of appreciation and residences that are easy to unload), speculators will boldly "chase the rising wave." Whether housing prices are high or low is beside the point. What's more, investors tend to herd together and pursue a few hot investment targets.
對投資型購屋者來說，只要投資成本低（貸款成數高且利率低）、預期效益高（漲勢凶猛且轉手容易），他們就會勇於「追高」，房價本身的高低反倒不是考量的重點。
