One strategy effectively used by developers to move otherwise stagnant inventory is that of the “loss leader”. They price one or two units in a building below market to generate interest, traffic and press. As a result, buyers attracted by value get acquainted with the building and may even get into bidding wars over those specific units. After losing out on the initial opportunity of the below-market apartments, they often opt for any of the remaining apartments.
The key is to recognize these opportunities when they arise while remaining disciplined about your original pruchase intention.
