According to official sources, the name "Ang Mo Kio" comes from a combination of rambutan trees and some bridge found around that area.
This "ang mo" and that "ang mo" are very different ...
Which "ang mo" do you think will be found at Centro @ Ang Mo Kio, and which "ang mo" at Sui Generis @ Balmoral Crescent?
Even with price movements, there should be a differential between prime and suburban properties.
The situation now seems that the price of suburban condos has shot up very high, while that of prime condos is still very subdued. For example, Ardmore Park, the Creme de la Creme of condos, is going for only around $2,400 psf, barely two times the price of the Centro @ Ang Mo Kio!
I don't think people staying at Ardmore Park earn only two times that of those buying Centro. Ten times would be a closer ballpark.
If it were the stock market, this would present an excellent arbitrage opportunity. Buy one put option for Centro at $1,200 psf and buy one call option for Sui Generis at $1,200 psf.
Whether the market subsequently goes up or down, sure to make money!
