This Prospect Heights townhouse has plenty of space. It is an especially large double duplex — 20 feet by 50 feet — on an extra-deep, 128-foot long lot. It also has some details: a stripped mantel, molding, a pier mirror peaking out of the edge of one image. But all of the interior photos are of the parlor floor. The write up touts the renovated kitchens and baths, but without the photos its impossible to know what kind of job the owner did. Also, some prospective buyers might take issue with the layout. The kitchen in the lower duplex is on the garden level leaving the parlor floor, which opens into one massive room, as the only place for bedrooms. The ad says it can be delivered vacant. It was an open house pick last month. Did anyone see it? In this market, will it fetch the $2,790,000 asking price?
