Much of the country is at high risk between fires, hurricanes, tornados, tidal waves, earth quakes, rising tides, etc.  

Quote from @Chris Wilson: @James HamlingNot trolling but just trying to provide some context about why states and other countries like CA have such stringent earth quake codes that keep getting updated.I will never really understand the power of a Cat4 or Cat5 hurricane until I experience one.

Nobody remembers the just start, only the infantile tirade and the destruction it wrought.

I experienced the 1989 Loma Preita quake on the 3rd floor of an office building along SR 92.

I have tenant that is from CA that is worried, they're used to earth quakes and fires.

And anything within a block or so of the ocean is going to take an incredible beating from the winter weather salt air etc etc.. and then you have the Tsunami that is coming with teh massive earth quake that will come and that will wipe out whole towns on the Oregon coasts.

If there is earth quake and property falls into ocean or anything else that brings value to $0, you can at most lose 30% of property value 3) most investors do not irresponsibly spend the all the extracted value.
