Say for example you buy a building, and you buy insurance. The insurance costs you 10% of the amount of money you make.
Then a natural disaster strikes and the insurance companies in the area all bump up the price of insurance to say 70% of the amount of money you're making. Is that about "proper preparation" or is this just 9a changing world and bad luck?
Proper preparation can, in many cases, make that difference, but at the same time there is an element of luck about everything. People buy a home in a nice area. Ten years later property prices have dropped massively, happened in Detroit.
How do you properly prepare for that?
