Want to make $70,000 a year? Well, listen up. First, you’ll need to invest in this bluest of blue-chip properties. Built in 1915, “Holly Court” is a “classic” center-hall Colonial with more than 9,000 square feet of living space, including eight bedrooms and nine-plus bathrooms. With high ceilings throughout, a large living room, an eat-in kitchen and, outside, an in-ground swimming pool and tennis court, the home is great for both family and guests. And if you know a few who want to stay on a more permanent basis, the 10-acre property includes two cottages with a potential annual rental income of $70,000.
