Mortgage company withholding insurance proceeds
Have you found a general contractor to rebuild your home? I would imagine that someone with a bit of expertise in the area is used to dealing with insurance companies, floating the money for a rebuild, and hitting the gates to receive payment for work accomplished.   Business are used to not receiving payment when work is accomplished and it is part of the risk of being in business.  They have to buy materials and pay employees with the expectation of payment in the future.  Much like workers go to work on a Monday for the work that day, three Friday's later, business often have to float costs but for longer periods of time. If you are looking to be your own general contractor then you will have to float the money on your own. The money should not be used for living expenses or mortgage payments, it should be used for down payments in order to get the work of rebuilding started.
