I attempted to write in as well regarding the Additional Housing Grant. The lady replied me said that we MUST produce the ROM cert when collecting the key date.
If ROM is planned 2.5 months after booking of flat, but key is ready let say 1.5 months later..we can postponed the collection of key until 2.5 months later... but we must take the key within 3 months.
In another word, no further deferment is allowed if you want the grant. I was thinking if i did not apply for the grant, and HDB also don't allow me to extend my ROM until end 2008 to do it with customary, then in the end i still had to hold my ROM separately. I will lose both this way.
My friend told me to ask HDB to defer over 6 months after the collection of key is very hard. Depends on your district, i heard the pioneer district very NIAO with deferment. My friend recently got a flat elsewhere and only request for 1 month further deferment, and had to appeal again to get it.
I guess the safest is to go through the ROM within 3 months from your booking of flat. That's going to be quite rush!
