Don't need to think so much everyone should have realized. It
doesn't cost more than 50k to build a HDB flat unit. In fact,
people in the industry have said that it cost around 20k-30k cost
per unit. 3,4,5 room unit, how much space bigger only? Just that
have more cramp rooms mah. 
If you can't afford, rent. Makes no difference from a 99yr
leasehold from HDB. Your house will still be your liability unless
you intend not to live there and sold it for a profit. Can we be
100% sure that we could sell it at profit in the future?
If you are struggling to make ends meet, isn't it better to pay
$600 rent per month than $800 monthly instalments?
If your income is not very high, you would most likely stay in
the house you bought for life. So would your life be better if you
had paid $600 than $800?
Of course there are other good reasons to buy your own house.
Leave it to everyone to think about it. It's just an example.
