We have considered these and other factors in determining whether the taxpayer's characterization is unreasonable. The other factors so considered include: (a) Whether the undertakings are conducted at the same place; (b) whether the undertakings were part of the taxpayer's efforts to find sources of revenue from his or her land; (c) whether the undertakings were formed as separate activities; (d) whether one undertaking benefited from the other; (e) whether the taxpayer used one undertaking to advertise the other; (f) the degree to which the undertakings shared management; (g) the degree to which one caretaker oversaw the assets of both undertakings; (h) whether the taxpayer used the same accountant for the undertakings; and (i) the degree to which the undertakings shared books and records.
