The house that the film's plot supposedly occurred in still stands in Amityville, Long Island. While it remains a popular walk-by spot, especially on Halloween, the iconic wedge windows have been replaced and the paint is different, to make it look less like the popular image of the house.
The house built for the movies in Toms River, New Jersey has been extensively remodeled (the wedge windows are gone and the gambrel roof has been replaced with a regular one) and repositioned on the property as to not make it visible from the street.
Christine Belford, who played Regina Cunningham in the film adaptation of Christine, lived in the house at 112 Ocean Avenue from 1960-1965. Her parents sold the home to the DeFeos.
