What to do if nobody wants a piece of your $30 million Bridgehampton castle? Well, if you're Christie Brinkley, you could just put your lesser North Haven spread on the market instead. And that's just what the model has gone and done! According to the Wall Street Journal, Brinkley listed her circa 1843 Greek revival home because "not one potential buyer" stopped by her infamous Tower Hill property on Brick Kiln Road. At $15.75 million, the new listing—a mere drop in the bucket of Brinkley's extensive real estate portfolio—offers 5,500 square feet and 4.5 waterfront acres. It also offers the opportunity to live next store to the entrepreneur, who recently invested in a $9.9 million property "directly across the street." Seriously, how much real estate can one woman own?!
