I could pay $20k to dry one out, or I can save $20k and be like every other place.

As you probably already know, entity protection is not really a cut and dry standard, it's a cross reference between the value of the asset, the risk or liability the asset possesses. 

My house is not 100 years old and has wood siding on it.I replaced a couple of pieces from dry rot 6 months ago and now I have a couple more pieces.

Be proactive now to make sure all the water soaked areas are dried out. 

Then dry the cloths in the drier.

With flooded homes do I need permits, inspections, etc or would just replacing the damaged dry wall, and flooring (fixing the damages) work?

@Paul Leech - My understanding is that program had dried up. 

Mold needs moisture and food, dry it up.

If you keep leaving cash in the deal your bucket will eventually dry up.
