There are many reasons. Firstly you have to look at the current economic situation and the fact property is dropping in value rather rapidly. Long term it will recover but where do you really want your money tied up? In a house that may drop by 30% next year? Or maybe you would prefer to build modular which could also allow you to adapt and expand as your budget allows rather than trying to find large amounts of cash you can literally do this in segments depending on your design. Big advantage of that being you don’t owe the bank! There are a lot of properties within container designs that make them an ideal starting point for a new house or cheap accommodation for renting out. But first you have to decide is it what you want..
