Is it normal that i think buying property is unwise?
Unless you are extremely rich, buying property usually involves getting a loan. You have to pay back loans. The only way to do that is to either do so slowly over a very long period of time, or to sell the property. Given that you cannot predictably sell a house whenever you choose (especially in today's economy), buying property is potentially like giving yourself a prison sentence. If you wanted or had to move, you might not be able to.
