New EC and how much to pay

The new EC at Buangkok is asking for $730-$750 psf and the buyers are those within the $8k-$10k income group. The average price of a 3 bedroom unit is around $850k. Presumably those earning more than $10k pm are too rich to buy these cheap flats.

What would this amount mean to a young couple who probably have worked for less than 5 years? Assuming they could cough out $100k for the initial sum,
