I think most of us here not so visionary, we just want a good investment or a nice place to retire without worrying about leaks, floods, burglars and Mozzies(not just the insect itself but the dengue it carries). Those are something we really need to think about if buying a property in Johor.
That is why people buy houses or invest all over in different parts of world and in various form of investments.
So that if one is flooded, there's always another one which is not. Everything got risks, even in safe Singapore. But it is how you spread out the risks so that eventually you still have something to hold on.
