The Priestley property, purchased in 1794 at a total cost of £500 (£  in ) from Reuben Haines, who had secured the patent to the land for Northumberland, comprised four lots of the original village plan (numbers 29–32). Currently, the house and grounds occupy 1 acre (4,000 m²) at 472 Priestley Avenue. (The address of the house was originally "North Way", but the street was later renamed in honor of Joseph Priestley.) This street forms the northwest boundary of the property; the other boundaries are Hanover Avenue to the northeast, Wallis Street to the southwest, and the North Shore Railroad to the southeast. Beyond the railroad line is a baseball field, and beyond that lies the Susquehanna River, which was the original southeastern boundary of the property. The confluence of the West Branch Susquehanna River with the main (or North) branch of the Susquehanna is a short distance southwest of the property, which is at an elevation of 456 feet (139 m).
