Va. Code Ann. § 58.1-3202

Beginning with assessments effective on January 1, 1984, the fair market value of multi-unit real estate leased primarily to residential tenants shall be determined without regard to its potential for conversion to condominium or cooperative ownership. A sale of apartment property shall not be presumed to be for such conversion unless overt action which is a prerequisite to conversion by the buyer has been taken within three months from the recordation of the deed.
