My house is fully paid. So is my car. My other 2 investment properties are also self financing as the rental can cover the mortgage instalments. Other non liquid assets are some shares, plus of course unwithdrawalable rubbish CPF monies.
After all that, I have still S$150,000 savings sitting in the bank earning meagre interest rate.
Wat should I do with this idle cash???
If you think the business model works, can consider starting a licensed moneylender business.
