Back to the premise in the first post.
My ATF does an overnight with me for about $3000, and that's about 20% less than her advertised rate for 12 hours, but I get almost 24 hours for that. So hypothetically, if I wanted to book her for a whole month, she'd probably charge me something like $60k. Maybe $300k for a whole year.
So hypothetically, if I had $50M in the bank, I could invest very conservatively, and live off $1.5M/yr, and my balance would keep going up as it earned interest. I don't know if I'd want to give her 20% of my income, but I'd be fine giving her $150k for the year, and having a non-exclusive arrangement, where I can see her unlimited, but she still takes as many other clients as she wants.
