For any property near Midvale, the Washington County property owner search returns who the tax bill goes to. This county guide covers: which viewer to use, what trusts, estates and LLCs mean, and how to confirm with the deed, at least around Boise National Forest.
Running a Washington County property owner search step by step
Open the Washington County ArcGIS parcel map to start; search by address, owner name or parcel ID.
The viewer Washington County publishes
Begin with the Washington County ArcGIS parcel map; it includes each assessed parcel from Boise National Forest to Cambridge. When a rural tract has no street number, pan along the nearest road and click the parcel itself, which applies near Deer Flat National Wildlife Refuge as much as anywhere. With a lot near Cambridge, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Trusts, estates and LLCs
For acreage around Cambridge, the record lists the owner of record, and that isn't always a person. An estate listed as owner near Cambridge often points to an open probate, so the personal representative is the contact.
Sections, lots and bearings
Idaho uses the Public Land Survey System, so deeds around Payette National Forest reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Deer Flat National Wildlife Refuge can be irregular. Copy the legal description from the record for the parcel near Weiser when you talk to a surveyor.
Deeds, plats and who keeps them
Before you sign anything, pull the recorded deed from the County Recorder (the county clerk serves as recorder); the parcel map near Payette National Forest only summarizes it. For property near Weiser, use the document number shown in the record panel to skip a name search.

Taking the map into the field

Getting answers from the right desk

Tax data in the record

Reaching an owner
A short letter to the mailing address on the record works better than knocking unannounced about a tract near Weiser.
