I might agree to a clearly defined short term lease contract (quite ironclad, of course) for a small PERCENTAGE of it. But even that would be a sublease because as others have already said, it's not really mine. It belongs to The Guy In The Head Office Upstairs.
As for what I'd want in return...
To be 22 again,or accepted as being that age, but with my current memories, knowledge, and skills, and to be a freshly commissioned 2nd Lieutenant in the U.S. Air Force, in training to fly F-16's, and on a guaranteed fast track to the Pentagon and multiple stars...and to remain on flying status for my entire career. And guaranteed perfect health to the day I die at some ridiculously old age, dying by misadventure only. And a marvelous woman to share it all with, forever.
Not bad, huh?
