no need so strict la. if subsale, sometime the seller can close one eye.
i think mine was 1 month or 1 1/2 month

end of the day, its up to the seller whether they want to enforce some of the rules of the snp like demand of interest for late payment of proceed. Just make sure the day u sign the booking slip date does not exceed 14 business days. Always follow up with your banker and remind them to release payment before the due date, specifically mention u are not going to bear the interest if the fault due to the banker side. On the safe side,u can write them down in a letter and state your intention. The point is chase them until they release the payment, any hiccups in between ask for reason. Call up everyday then they will know u mean business.
