This just shows that properties are actually becoming more and more affordable.
In 1970, a Katong Seaview Palace semi-detached at Lucky Crescent was asking $90,000 but the President was earning only $4,000 per month (or $48,000 per year) so it would have taken the President 1.9 years of salary to buy this house at 41, Lucky Crescent.
Today, an equivalent semi-detached (49 Lucky Heights) was transacted at $3.8 million on 28 Dec 2009 but the President is earning $3.2 million per year. So it would take the President only 1.2 years of salary to buy an equivalent house.
The President's salary is one of the best benchmarks to use because there is only one President (we can also use the Prime Minister or Ministers, or the any other job with a limited number).
What many people have wrongly done to claim that properties have become unaffordable is to use graduates' pay as a benchmark.
There are 40 times as many graduates today as in the past but instead of seeing their pay reduced by 40 times because that would have caused a riot, what happened was that property prices went up by 40 times.
However, there is no change to the type of house(s) owned by the top doctor in each field, top lawyer in each major law firm, or top towkay in each business, compared to 40 years ago.
