Hi, cos eample if i have excess $20K in OA, if used for prepayment, it will reduce principal by $20K, thus interest saved is 2.6% of $20K. but if i leave $20K in CPF OA, it collects 2.5% in interest. Like not much difference isn't it? Cos i thought that since hdb got insurance, anything happens, the remaining loan may be covered partially. So no need to clear off the loan so quickly. Pls correct me if my understanding is wrong, thanks.
