This folder contains correspondence and other documents relating to Edison's real estate holdings, along with unsolicited letters offering to sell land or construction services. Among the correspondents for 1915 are William Carman, Edison's former bookkeeper at Menlo Park; Isaac W. England of the Passaic Metal Ware Co.; and real estate broker Alfred D. Hyde. The selected documents include a plan to combine and sell several lots in Menlo Park, where Edison and Carman both continued to own property. Also included are letters pertaining to the availability of mineral rights on Edison-owned lands and to the valuation and possible sale of properties owned by Edison's businesses at Glen Ridge, New Jersey, and 10 Fifth Avenue in New York City.

Approximately 10 percent of the documents have been selected. The unselected items consist primarily of unsolicited offers of land or factories for sale in various cities and states, which were generally marked "no ans" by Edison.
