Military Ordnance Locations Disclosure
Federal and state agencies have identified certain areas once used for military training and which may contain live ammunition. A seller of residential property (again, 1 to 4 dwelling units) located within one mile of such a potential hazard must give the buyer written notice thereof as soon as practicable before transfer of title. This obligation depends upon the seller having actual knowledge of the hazard.
