A riverfront mansion in Rumson may put a new spin on the concept of real estate teardowns. The 12,000-square-foot house at 8 Navesink Avenue, with eight bedrooms and 12 bathrooms, was razed recently. The property was the subject of a live auction in July, 2013, when it failed to attract a single offer at the minimum bid of $2.6 million. Four months later, however, it sold for $5.6 million to Dennis and Marshall Lynch, according to Monmouth County records. The Lynches won planning board approval in April to build a new residence on the 1.9-acre site. (Photo above by Michael McMahon. Click to enlarge)
