Stars: They’re just like us, right? (Oops, wrong magazine.) Unlike mere mortals, bold-faced names can really bolster their bank accounts simply by unloading a premier property. Julia Stiles recently did so, pocketing $2.7 million for her three-bedroom duplex with two wood-burning fireplaces at 310 East 15th Street (she purchased it a decade ago for $1.995 million). In SoHo, Jonah Hill’s full-floor Howard Street loft was recently listed for $12,000 a month; it boasts 13-foot ceilings and a fireplace, but no doorman expecting a holiday tip. A few blocks away, Kirsten Dunst’s Canal Street penthouse has just been snapped up by a new tenant.
