To be fair that is how the house in sports betting tries to work. They adjust the odds, the payouts, the spread, or whatever they else need to do to make money irrespective of the result of the game. The house just takes their cut.

It has already happen. Look what happen in 08. The banks did the foreclosures and then just sat on the properties or sold them in mass to someone else. There wasn’t any auctions on the courthouse steps for the local populace to bid only a dollar.

No. The auctions wouldn’t happen in person but online. Some reit or foreign money or both will bid more than the locals could afford.
