Arlington Heights is a bit vague, perhaps, but frequently encompasses the area centered around the intersection of Mass Ave and Park Ave, and then everything from there toward Route 2. Many people will reference anything “further out” than Arlington Center as being “up the Heights”. The real estate is a combination of Victorians around the Arlington Reservoir area and the immediate Park Ave area, early 20th century closer to Mass Ave and post war homes as you move toward Route 2.
