1. Make sure you can rebuild all, not just part of, your house

Don’t make the mistake of assuming that just because your home’s value has gone down that the cost of materials and labor have gone down, too. For example, home construction costs rose 1.3% from January 2009 to January 2010, according to construction cost consultants Marshall and Swift/Boeckh, even while many homes were falling in value. Make sure your home owners insurance pays you for full rebuilding costs in the event of a disaster.
