Yo bro, you must be busy with your new born, congrats.
It seems that for those taking a grant, it only make sense if the levy is below the amount of grant taken. However, the resale levy is to put a stop to those looking at flipping a HDB flat.
I think if buyers continue to speculate in a basic HDB flat, hoping to make a windfall out of it then this might be a problem (don't make as much with the levy). For those who are just looking at a roof over the head, this levy may mean nothing.
Point is, most 2nd timers usually either buy a resale HDB, wait for a new BTO/EC or switch over to a private property. I don't have the numbers but a second new BTO flat for a second timer with the levy added is still reasonable.
