In the real world, it would be pretty expensive to live like Barbie — especially when it comes to housing. Consider Airbnb's life-size Barbie Dreamhouse rental in Malibu, an all-pink mansion decked out in Barbie décor, for example. That's a pretty high credit score; any score between 740 and 799 qualifies as "very good," according to Experian. While the oceanfront estate is privately owned and isn't actively for sale, several real estate companies have given varying estimates of what it may be worth. RubyHome estimates the pink mansion is worth about $10 million, Mariotti says.
