this is relative. If you are buying a big ticket item, it make sense to pay by installment so that you can re-invest the money to generate income. If you are looking at small value item, it is better to save on the interests to lower the cost of ownership. Again I say this is relative to different people. i have friends who buy car paying in one lump sum cos they can afford to. Imagine the amount of money they can save.
In TS case, I am sure he is not taking up a loan to generate income with the remaining money. He is taking up a loan to pay for the purchase by installment. In other words, spending money that is not in his possession. This is a bad habit that should be avoided, else it is the beginning of the love and hate relationship you have with the bank. The bank will send you love letters to entice you to BBB. Then when you default on your payment, they will send you hate letters to PPP.
If one thinks he can be so discipline and sound in managing money, then wouldn't going to the loan sharks be even better? They offer higher credit limit, lower interest rates, allows you to pay in cash and they come to collect money from you. why need to use credit card for interest free payment? One need to know the modus operandi of credit cards is no different from loan sharks.
Anyway, TS enjoy your lens.
frankly speaking, its not that i dun have the cash for lump sum payment.
diff ppl diff mode of payment. diff thinking
