There probably was some real grass smoked with the production crew as well.
But that is neither here nor there. The home seems just a bit inflated, (as in someone trying to get a high price just for owning "The Brady" home. In LA, that may indeed happen.)
There is a bunch of stuff on the interwebs about this house, and how the interior is completely different from what was shown on the sitcom. In fact, if you look at the photos of this home (real photos), the floorplan on the tv show makes little sense. But who cares? Absolutely nobody.
I predict someone will overspend for this home based on nostalgia and way too much money in his/her bank account. But if that rings their chimes, more power to them!
