In Royal Parke Corp. v. Town of Essex, 145 Vt. 376, 488 A.2d 766 (1985), where the Court considered the fair market value of seventy-two identical condominium units, we held that the fair market value was "sufficiently established" when two had sold and seven others were under contract for sale at the same price. 145 Vt. at 379, 488 A.2d at 768. The Court observed that, beyond the requirement of a bona fide sale, "the tax statute is not concerned about the reasons either buyer or seller attributed the agreed value to the property." Id.
