I would imagine a real estate appraisal might be a good a place as any to start so you can get a better idea of the worth of the house/property -Realtors do it for free sometimes or for a small fee. Don't know that I would rely on the bank to do an appraisal. Home improvement loans based on equity was a good way to go ,but those banks got pretty iffy on that.
I can go back five years or more on remodel loans- case where the clients bought a building and secured a sizable loan to convert the office building into something more suitable.A matter of changing over from a wing in a high rise to their own commercial building. I think they used Wells Fargo and had a lot of good things to say about that bank along those lines. They also have advisor's on hand at that bank for your situation. Actually the bank you choose for this is important-not just any bank will do. You want the best deal available.
Now on the storm damage issues, I am not at all sure how the banks respond to that. Bin Sober seems to have a handle on what goes on with those banks under the circumstances.
No matter what you do ,you want to put your money in the areas where you will see a return at the time of sale as your home is your greater investment.
A home property appraisal may be the place to start. Because in that appraisal will also be potential worth through upgrades.Where to spend and where not to spend is all and important.
With that a appraisal /assessment separate from the banks assessment/appraisal you would be better positioned to lay out your ideas for upgrades in line with increased value.The worth of the house property after upgrades- renovations ,remodels so on.
The bump outs-dormer-s should add to the worth.A common practice when flipping an old house.
And on a side note- I don't know that I would trust any contractor outfit your insurance company suggest you use.! Usually such outfits work in cahoots with the insurance company which isn't good for you. !
