I tend to look at the insurance company's take on these kind of things for a more clinical rational analysis. Compare rates and try to ferret out why they are what they are. Yes, its come to that..
I'm starting to think about ditching earthquake insurance.
I'm in a modern home, so I'm not making much of a claim if there's a smallish earthquake. But if there's a big one, I assume the insurance company will just go under, leaving me out the premiums and with no recourse.
