Flooded slab ranch house - issues?

[Christian Carson]

I just looked at an auction property with about a 100k ARV. Someone removed the water meter and there is no shutoff on the supply pipe--when I walked in, there was water gushing out and 4 inches of water in the whole house!

The house is a 3bd/2ba 1969 slab home with forced air ducts in the slab. It's got good potential with new windows and doors. The house sits on a hill so the lot has good drainage.

The temperature is currently below freezing, so I'm also concerned about the water freezing in the house.

I'm wondering if anyone else has had experience remediating flooded homes. I don't think the house has been flooded for more than a week and the auction is happening at the end of the week.

I'm not afraid of complete tearouts, but I'm wondering if I'm going to run into problems with a sinking slab or under-slab utility problems. Can anyone give me any insight into this? Thanks!
