The Midwest is going to benefit, no doubt. Away from the coast, no hurricanes, fires, floods - we don't even have snowstorms anymore.
People can deny climate change all they want or blame it on sun cycles, and frankly, it does not even matter, the reality is that insurance cost will force the issue.
You can try to rebuild and you can put houses on stilts in flood areas, or fortify them against high winds and fires, but that makes it expensive. And it's not only the homes, you also have to fortify your grocery stores, schools and anything else. Keep your automobiles safe.. This is one of the things that sound a lot easier than they are actually done.
The crazy thing I learned about these CA fires is that the heat radiation is hot enough (1500-2000F) that it will ignite your furniture through the windows. Wood ignites at 700F, fabric a lot sooner. So yes, you can have solid concrete walls, it's still going to burn down.
I have read that worst case up to 80 million Americans will relocate in the next three decades. That seems extreme to me, but even if is only 10% of that, that's more than our States entire population, the implications are supermassive. That would mean entire metro areas would become ghost towns and entire new metro areas would have to be built. For reference, we currently build 1 million homes per year just to keep up with current demand. Now we have to build how many millions extra? And it's not only homes, it's all the infrastructure a city needs.
On the insurance issue, I think this may be the end of national carriers. I am going to see if I can switch to a local Wisconsin insurance that reflects our local risk level in their premiums.
Many of the homes in the Pacific Palisades are 3-5 million, but when you look on Google Street View, most are very modest homes from the 1960s (there are some $20m ultra luxury mansions too), so a lot is the land value, the home replacement value on a 1600sqft may be what - 500k at the most? Most people are not rich there, look at the cars. I am not sure what the means for insurance payouts, replacement value and property value are VERY different - does anyone know?
There are lots of listings currently under contract, I guess the buyers are not going to show up for closing next week..
And also rents! I see two high end homes for rent, 50k, 70k, 210k per month.. I guess not anymore.
