An interesting thing for me right now would be to check on people who are being foreclosed upon.
We've all seen or heard of houses being stripped. I've asked, "why aren't these guys being prosecuted?"
The answer is that you have to prove who did it. And if you do that, they can always say they were in the middle of a remodeling project, then the house was suddenly taken away from them.
Anyway, I would bet that between the owner/occupier and the banks, someone is reporting a theft.
Maybe the homeowner removes all the appliances, furnace, etc. and reports a theft and turns it into his insurance.
Maybe the bank has insurance for this. They get a house back with everything intact and go and strip it and report a theft and collect.
Maybe a realtor lists a house and all the appliances show up missing and they call in a theft. That would only be theft, not insurance fraud. But maybe they are in bed with the bank, and the bank gets the insurance claim and splits it.
So check into that end of it.
