I am talking about a situation where a developer is unable to repay their debts due to an unsuccessful project. The assets may still have some value, but probably far less than the debt. And any buyer would have to believe that they can succeed where the original developer failed. That may still be possible but the list of potential buyers is very limited.

Also, the amounts of money are so vast that they would stretch most companies. Without massive cash reserves you are back to raising capital and the problems discussed.
