Millionaire's Cheap Rent for a Park Ave Penthouse

A new lawsuit filed by an unhappy Park Avenue resident with a seemingly charmed life has us wondering: how many millionaires have fantastic rental deals? Or, more to the point, how many of us have a grandfather who will leave us with a deluxe duplex?

It's hard to say since people in New York City with cheap rents, millionaires or not, tend to have the good sense to not divulge what they are not shelling out each month. But at least one sweet deal has gone public, leaving tongues wagging and real-estate obsessed New Yorkers wondering about other much cheaper-than-expected arrangements.
