anyway, just few points.
1. rental insurance usually carry 12month, I would suggest tenant move out or to another property, to avoid further liabilities.
2. insurance will send their adjustors out, don't do anything before they arrive.
3. cost of fire truck run/ board up house, usually separate coverage item, just forward bill to insurance when you get it.
4. most insurance company use standard estimate software, usually pretty close, you can still debate on individual items.
5. you can hire your own construction company for construction, yes you entitle to 10% overhead and 10% profit, to your policy cap.
6. if you have mortgage against it, check will issue to bank and you, and bank will open escrow for your construction company.
7. if no mortgage, check will issue to you and construction company.
8. congrats to your 50+% profit on the fire.
