Frankly speaking, IMHO, HDB income ceiling of $8k don't need to be raised. How many people are affected by that $8k ceiling buying their 1st property? Fresh graduates generally about $3-3.5k pm only, so that $8k ceiling is a good incentive for them to get married and get a HDB flat early.
Instead, they should just increase the supply and ensure that the 4-rm HDB flat price remains affordable to median income families. The rest will scale accordingly.
And the private property market sector only affects like 15-20% people, why should they go and meddle unless there is a property bubble or for some other unknown reason (e.g. got conflict of interest or not?)? And there isn't any bubble for now (since they can't even define what is a bubble properly!). The price increase seems to be inline with the increase in income of the top 20% earners. It is that private properties are just too cheap previously and not that they are too expensive now!
