Some real estate investment experts say an advance sales completion rate of 60-70 % indicates a buoyant market in which house prices will rise, and a rate of 40-50 % shows a stable market. But if the rate drops to 30 % it shows supply is outstripping demand, so house prices are bound to fall.
按照部分房地產投資專家的說法：當預售屋銷售率達六、七成時，顯示市場活絡，房價自然上漲；銷售率在四、五成時，房價平穩；一旦銷售率低於三成，表示市場供過於求，房價就會下跌。
