Answer: I tried using the URA website to get transaction data before. It was quite difficult (at least from my personal experience).
I have designed the RED portal to be easier to use. I hope that visitors will find it easier to get all relevant information about a condo or housing project from the RED portal.
I also developed the concept of BMP (benchmark pric), AMX (amenity index) and comparables (i.e. similar projects in the same postal sector).
