I spent the last few days helping my parents clean up. Only 2 or 3 inches of water in the house. Thankfully, the power was on when the water started receding. My Dad had a shop vac going to draw out the water. Water was only in the house for 4 or 5 hours. Looks like they don't have to tear out any sheet rock. Most damage was confined to stuff on the floor. The flooring downstairs is all tile or vinyl on concrete. It is might need replacement at some point. We spent a couple days emptying out closets and moving furniture and cabinets to make sure there was no water left. They have several fans blowing, 2 or 3 dehumidifiers, and all the A/C's blasting to make sure things are dried out.
My Mother had a small mountain of craft materials and books in her shop from sewing, porcelain doll making, painting, etc, etc. It took the better part of a day getting most of the stuff pulled out and hidden water cleaned up. That was the lowest spot. I joked that I think my Dad may have run a garden hose into her shop just to make sure. My Dad's fairly new tractor was okay as well as all the vehicles.
Could have been worse.
