I have a friend who's business partner is seriously loaded, cash-wise.
The guy puts a For Sale sign on everything he buys the day he gets it home with the price he paid for it plus 10%.
The two strangest things I've ever seen him sell were a 200' crane he bought to bid on some tower work that no one else wanted and/or knew about that he used for various odd jobs and rented out to friends for a couple of years, and his Class C motorhome.
The crane made him serious money. He used the crane to remove gear from old tower sites, then purchased two sites with the proceeds from that work. Continued cleanup of the buildings and fixed 'em up, and companies then bought the sites from him at a profit. He's always doing crazy stuff like that. Hopelessly addicted to weird projects only he seems to figure out.
Flipping houses looks easy compared to the commercial properties he flips. Radio tower sites? Yep. My guesstimate was that he made $300K after sitting on them for a couple years. Not including site rents by tenants in-between.
Both the crane and the RV had people call him from the For Sale signs and hand him cash for them. They "had" to have them.
He got to use them both for roughly two years for free even including fuel and maintenance. Maybe his only loss would be insurance.
Crazy. There's a sucker born every minute as P.T. Barnum said.
I doubt this technique works with airplanes very often.
