Floods: First, don't wait too long. If you know your area floods, learn the signs and get out while you can. You may also want to have some sort of water craft, particularly the inflatable kind. Documents, including your Flood Insurance, may be a good idea to take with you.
As much as it's advisable for you to have broad coverage, too much coverage isn't advisable either. Take stock of your valuables on a regular basis and take note of their present market value. This exercise may show you that you have to buy more coverage but it could also show you have too much and therefore result in savings as you reduce to the right coverage limit for the time.
You'll realize bigger savings if you buy a house as close as you can to a police station. This as well will help in lowering your homeowners insurance premium.
A burst pipe, a leaky roof or appliance, a hurricane or strong storm. All of these scenarios are seen everyday around the world. If you think that it can never happen to you, you could be in for a horrible surprise.
It's not enough to prepare for a flood when you first hear the flood watch. Advance preparation for a flood can save your life and the lives of your family, as well as reduce the financial impact that can tie your family up for years.
At times, rather then provide housing for ourselves, it would be so much easier and cost effective, if we could just find a hole in a huge tree to sleep in but then scavaging for food would be almost a fulltime job! So in conclusion, I guess our basic need for housing as humans isn't so bad after all.
