*Open House Saturday 5/9 from 10am to Noon!!* White Mountains Contemporary Luxury 5 Bedroom, 3 Bathroom Home With Separate 1BR, 1.5 BA In-Law Apartment. With an Exceptional Short Term Rental History, and approximately 5,000 square feet of high-end features and finishes, including a chef's kitchen, maple walls, a wet bar, stone fireplace, in-ceiling multi-room audio speakers, Bose-powered TV room, study area, and an extensive wrap-around steel deck, this home excels at entertaining and is in a great central location to access skiing, hiking, fishing, boating, and everything the White Mountains and neighboring Lakes Region have to offer. In addition to the successful short-term rental history, there is a basement level 1BR and 1.5 BA In-Law Apartment with separate, ground level entrances.

The home is being sold furnished, and fiber-optic internet is available as well. Due to the busy rental schedule, select showings by appointment only.
