The units in Treasure At Tampines would be able to sell-off eventually with ease for the following reasons. One, the development is located at an housing estate with more than 200,000 HDB dwellers, but has limited condominiums. These HDB dwellers are potential up-graders to private condominiums at some time and most of them would prefer to reside within the same estate as far as possible. With such a big pool of potential buyers, it could be easily transacted, especially without any constrain like that of an Executive Condominium.
Two, as the development has more than 2,000 units, it would generate a higher transaction volume. This would notably translate into higher selling prices, as each transaction would likely to close at a higher selling price than the previous. This is because every seller would not want to sell lower than what they have bought and to make a loss in their transaction. Therefore, they are likely to compare and benchmark with the recent transactions.
Three, at a low entry price when buyers buy direct from the developer, the gain over this purchase is a given. When these buyers decide to sell their units subsequently, they would be able to price their units competitively, despite having already gained in the capital appreciation.
