Take a bigger loan at a low interest rate

Hi Mr. Tan,
I am in the process of looking for a housing loan. My friend advised me not to pay off the loan so fast, but to use my available cash for investments. Is it a wise thing to do? He showed me some calculations, to convince me that I would be better off taking loans and investing my cash. But won't I be losing from the high interest the bank charges?

If the interest rate on your loan is low (say 2.6% for HDB loan), you should be able to earn more than than this interest rate from your invetment, if it is invested wisely. You should avoid investment that has a high charge, especially if it is marketed to you by an agent or financial adviser.

However, if the interest rate is more than 4%, it is not worthwhile to take the investment risk.
