Aero Country Airport is a privately owned, public use airport. In other words, the on-airport structures are owned by individuals and the common property (runway, taxiways, access roads) are owned and managed by the property owner's association. The "public use" aspect has to do with aircraft not based at Aero Country having use of the runway without having to obtain prior consent. See the Airport Facilities Directory for additional info.
The property owner's association (ACPOA) does not track available rental properties or real estate for sale. The Classified Ads Page on this web site section has some postings of such available properties.
