Often delinquent tax parcels are unaddressed parcels that are not located on a public road or do not have an assigned address. In such cases, most localities have an online Geographic Information System (GIS) that allows the real estate to be looked up online. NOTE the GIS is not a survey and those lines depicted are created by the locality using best efforts to show the location and layout of the parcel, but reliance should not be placed on this information as an exact representation of the location, size or shape of the parcel.
