While I respect the "fight" of these 90210 mansion owners... the real question is what do you do with that much square footage?
I mean it isn't that much when you think about it... 27,000 feet are for a guest house... so that isn't really usable space at all... which really only leaves you with the roughly 42,000 square foot main house. So let's see a full sized basketball court is around 95 x 50 or 4750 square feet. So I could take maybe 5 of those and still have roughly 20k left....
I would need a source of income (and keep my demographics up) so I would put maybe ten 500 square foot apartments in my house... for some extra income.
I still have 15k left which leaves me with JUST enough to put my Olympic sized pool, Skyline Chili Restuarant, Stone Cold Creamery, and Red Robin inside and still have 7k to live in.
What would you do with 85k?
