This Mount Sinai house once belonged to Long Island artist William M. Davis, who lived from 1829 to 1920. In fact, the historic home, built in 1873, is very similar to the house depicted in his painting "Long Island Homestead." It's unclear, however, if this is the same house. The three-bedroom, three-bath home, which is on more than an acre of property, is on the market with the Ronkonkoma office of Prudential Douglas Elliman Real Estate for $399,000. While there is antique detailing, the house has updated appliances and a double oven. Davis, who was born in Port Jefferson, was known for his Hudson River School style of realism. But his Civil War-style paintings were popular -- one huing over the desk of President Abraham Lincoln.
