Finding Knox County land for sale on the parcel map
Use the Maine GeoLibrary Parcel Viewer to scan the roads out of Friendship; parcels without structures and with an out-of-area mailing address are commonly the ones owners will talk about. Recent sales on the county record give a rough sense of what land near Matinicus Isle has changed hands for, though a sales price sometimes covers more than the dirt.
Step one: the free Knox County viewer
Knox County parcels are viewed through a statewide map, the Maine GeoLibrary Parcel Viewer; zoom toward Cushing to reach them. Click any Knox County parcel near Cushing to open its record: owner, parcel ID and assessed acreage are most commonly listed.

Deal-breakers to check near Cushing
Start with access for a parcel near Cushing: check road frontage on the map, and read the deed for any access easement. Flood zones change what you can build near Cushing; look up the tract on FEMA's Flood Map Service Center. Check with the office covering Cushing about zoning, minimum lot size and splits, and ask the health department about septic.
Reaching owners of land near Friendship
If an open parcel near Cushing is not up for sale, the county record still gives you the owner's mailing address for a polite inquiry. Before closing on land near Friendship, get a title search and consider a survey; the county acreage is a tax figure.
Carrying costs for land near Isle au Haut
Check the annual property tax on the county record for a parcel near Isle au Haut; it's a recurring cost that a listing may not mention. Look at the neighbors, too: who owns the tracts around a parcel near Isle au Haut tells you a lot about what may happen next door.
On the ground near Friendship
Mineral rights and timber rights near Camden can be sold separately from the surface in some places, so ask the title company what a county deed includes. Ask neighbors near Matinicus Isle about drainage, roads in winter and anything else a county listing won't mention.
