Buying property is always good, because in the long run the property price goes up compared to fiat currency. However if need to take a loan from the bank to buy a property, then it may no longer be a good purchase. When taking a loan from the bank, one is at the mercy of the rich who deposits with the bank. When the rich withdraws the cash, the bank can call back the loan immediately or raise interest rate to attract other rich depositor. Problem is when the rich withdraws the cash, it is because they have found a better investment elsewhere. So the bank will not be able to attract cash unless they can beat the other investments with better rates. Normally that will be too drastic an increase for the debtor to bear.
