Wow! I haven't been in this sub-forum for a while. So, So sorry. I have an idea how you felt and feel. I went through a house fire some 25 years ago. It can really be a bummer. We lost a lot of family treasures. About 8000 to 10000 slides were damaged beyond real use. Many color and b/w negatives as well. I also lost some camera equipment. Furniture, damage to the house, clothes, books, electrical equipment as it get covered with acidic water.
But one must move on. We had a really good insurance agent who agreed they would pay for a complete rebuild rather than the repairs they first authorized; and it actually saved them money even though we got some upgrades.
But none of that was easy to get through, so as I said, I can feel your pain.
Hope all is going well with you. I will just add what others have said. If money does become a crunch factor, many of us here would be happy to send you some help, big or small, as we are able. I know you won't ask if you don't need it, as I have heard many times of your integrity. But it will be there if needed.
I hope all is going well with the rebuild and life adjustment.
