Bernie and Arnold and Hef, Oh My!

We hope young Petra Ecclestone is taking good care of her papa this Father's Day. It's not every day that a dad buys his 22-year-old daughter a house listed at $150 million (that's it above). Not even Hugh Hefner has been that generous with his daughters -- er, we mean ex-fiances.

On this Father's Day weekend, we'd like to single out a few dads who deserve special recognition, at least in the real estate world, for being generously spirited in the giving of houses. We pass no judgment on the wisdom of other choices they've made in the course of their lives.
