nowadays, inorder to get mortgage from hdb or banks, they will do background check on your debts, see if you owe any credit cards and so on. private property requires 40% downpayment...it only benefit those with high income. sinkieland is really a playground for the richy rich...
Using cash is a good idea but wait, indirectly you are pumping more money into CPF, which is irreversible and taking into account the minimum sum which increases yearly. And with the recent high cost of a new HDB flat, who would have the ready cash to purchase one?
