Hosts express concern that owners who sold to Air Pros and rolled 20-50% equity on the promise of a lucrative second bite will walk away with far less than projected following the bankruptcy, cautioning sellers to vet acquirers carefully.
“that's one of the sadder parts of the story is the owners that have sold. You know they rolled in equity. 20, 30, 40, 50 % who knows how much.”

They want to grow as fast as they can. They want to outpace the debt. This is an example of what happens when that doesn't work out.”
