Here's what you should know about the double stamp duty

Easing of DSD favours primary launches.

The double stamp duty (DSD) measure, imposed in February 2013 to rein in soaring property prices, was eased in May 2014.

According to a research and forecast report from Colliers International on 2Q 2014, buyers purchasing partially built properties can take advantage of an extended period in which to sell their existing homes and benefit from the DSD rebate.

The DSD amendment boosted buyer sentiment and increased home sales, particularly benefiting developers looking to target upgraders.

Here's more from Colliers International:

The amendment exempts upgraders from paying DSD of up to 8.5% if their existing unit is sold within six months of the completion of their new home sale (signing formal assignment).

The easing of DSD undoubtedly favours primary launches with owners no longer needing to offer aggressive price discounts to lure buyers.

With the stamp duty amendment in place, and no oversupply at present, those interested in upgrading are less rushed to sell their properties, resulting in a market with more resilient secondary residential prices.
