Due diligence on Marion County land
Start with access for a tract close to Gervais: check road frontage on the map, and read the deed for any access easement. Low ground near Butteville warrants a flood check on FEMA's Flood Map Service Center before you fall for the view. Ask the county or town office in Gates if the land can be built on or divided, before you make an offer.
What the surrounding parcels tell you

What the map won't display
Wetlands on rural ground near Butteville can limit building; the National Wetlands Inventory and a site visit help before you commit in the county. Check cell coverage and internet options at the tract close to Salem before you plan to live or work there.
