You know the mortgage does not go away just because the house is destroyed. In fact, current mortgage contracts are written so if there is any insurance it is paid to the mortgage holder and IF they decide you can rebuild, they release money in stages to do it on a big rebuild. If they decide not to do it, then the insurance is just paid to the mortgage subservicer and applied to the mortgage loan. The homeowner has to pay for any estimates and plans to get a plan together to present to see if they will get to rebuild. A lot of people trying to pay the mortgage and the cost of their temporary housing just cannot stretch that far. Even if they have insurance, if there is a shortfall, the homeowner is still
personally liable for the shortfall. So, the insurance company decides how much they will pay, the mortgage company gets to control it and effectively gets to make the decisions. The homeowner still retains personal liability even if they do not have a habitable property. Most people cannot pay housing costs twice at the same time!
That's the first chapter. The second chapter is that since the homeowner has made a claim on their insurance, their name goes into a "C.L.U.E." database.

If they make huge insurance claims or too many, they cannot get insurance or they have to go to a high risk market which is horribly expensive. So, no insurance, no mortgage -- and as it is becoming more common. It doesn't stop there. No rental either because landlords want their tenants to carry insurance.
Also, just making an insurance claim and getting put in the CLUE database as a claimant can lower your credit score. A lower credit score means paying higher mortgage rates. I think it takes something like 7 years for a negative CLUE entry to fall off the database. I have also heard some people are hiring attorneys to cut deals with the mortgage companies and insurance companies to pay a premium so they will not be entered into a CLUE database.
Thinking that just not reporting a loss will shield you? Nope. If the insurance company or mortgage company finds out you have a loss that you did not report, it goes down quite poorly for the insured/borrower.
And you thought a good credit history was all you needed for a good credit rating? Not anymore.
I am very empathetic for all those caught in storms or in any loss situation -- whether or not the local government declared an emergency. (Generally, that is required to get any assistance.)
