How to run a Columbia County land owner map

Reading owner names on Columbia County records

Before money changes hands near Starbuck, back up the county map with the recorded deed. A deed book and page or instrument number on the record near Dayton is the shortcut.
Writing to an owner near Dayton
If you want to contact a Columbia County owner, a brief note sent to the address on the record is the most reliable approach, since Columbia County records do not list phone numbers. In the letter, cover the basics: which tract close to Dayton, why you're asking, and how to reach you.
