For residential, the impact is only on new properties launching where the raw materials are subject to 6% GST.
For commercial, besides the impact described above, according kastam latest information, sales be individual owned commercial properties not more than 2 in a year will not require to include 6% GST on selling price. However, property owned by company is subject to GST. Hence, this created advantage for personal owned property owner as their selling price will be more attractive by 6%.
Please verify this fact as I am just sharing what I have learned from recent seminar briefed by kastam. Thanks
