Start with sales a buyer would compare with your land. Farm ground, a rural home site and a lot in town aren’t the same thing. Match the size, location, access and what sold. Then use those matches to build a price range instead of relying on a countywide price per acre.
1. Gather the Record for Your Tract
Find your tax statement, deed and any old survey. Save the parcel number, acreage and nearest road. The parcel number is the county’s ID for the piece of land. If you own several tracts, give each one its own line in your notes.
The Whitman County Treasurer’s page links to two different tools. TaxSifter is for looking up property and tax information. REETSifter is labeled Excise Affidavits Lookup. An excise affidavit is a form filed with a property transfer; it can help you research a sale.
Save both the land ID and the record reference for a possible match. Don’t assume a familiar road name means you’ve found the right tract. Compare the acreage and deed details too.
Need help finding the record? The Assessor’s Office lists 509-397-6220 and 400 N. Main Street, Suite 101, in Colfax. Have your tax statement or old papers ready when you call.
2. Compare the Same Kind of Land
Make a short description of your tract before you collect prices. This helps you set aside sales that look useful at first but don’t fit.
- Farm ground: Compare size, current use and access. Write down any lease, who farms it and which parts of the sale include buildings or equipment.
- Rural land: Compare the drive, slope, flatter areas, water and power. An easy-to-reach tract may attract different buyers from one reached across other land.
- Town lots: Compare lot size, shape, street access and services. Don’t treat a house sale as the price of a vacant lot.
Share any written access agreement, lease or water papers you already have. For unknown details, write “not checked yet.” You can ask for help before making a promise to buyers.
A large farm sale and a small rural lot may have very different prices per acre. Use the likely buyer’s choices to decide which sales belong on your sheet.
3. Check What Each Completed Sale Included
For each possible match, save the sale date, total price, acres and parcel number. Ask whether it was vacant land, land with a home, or a package of several tracts. Keep the complete package price separate from the price of one parcel.
If you see the same location in several entries, check the parcel numbers and recorded transfer before counting them as different sales. Different road wording can describe the same deal.
The county’s Recording Searches page explains how to look up summaries by name, parcel number or Auditor File Number. That file number identifies the recorded document. Public Login shows summaries; viewing a full document online requires registration.
You can ask the Auditor’s Office about copies instead. Its official directory lists 509-397-6270. The search page says records filed before 1982 aren’t available online. Ask what to bring and what a copy or search costs before making a trip.
A deed reference helps confirm which land changed hands. If the sale details are unclear, ask a land agent, appraiser or closing professional to review them before relying on the price.
4. Make a Simple Price Comparison
Give each good match one line: date, parcel number, acres, total price and what sold. Add one similarity and one difference. Keep a note about where the record came from.
In a made-up example, 80 vacant acres sold for $240,000. Dividing the price by 80 gives $3,000 per acre. That doesn’t mean a five-acre lot nearby is worth $15,000. A smaller tract, different access or a different use can change the comparison.
Start with the closest matches. Set aside sales with buildings if you can’t tell what part of the price was for the land. Also separate special transfers, such as gifts, from ordinary sales between a buyer and seller.
Use a range rather than one exact number. If you find too few good sales, ask a local land agent or independent appraiser for help. Ask them to show the records behind their suggested price. Our land value guide explains more ways to compare.
5. Keep Tax Values and Asking Prices in Context
A tax value, a seller’s asking price and a completed sale price answer different questions. Check the year and whether buildings are included before using a tax figure in your notes. Ask the Assessor’s Office if the land details don’t match your papers.
The county’s GIS page directs users to TaxSifter for more current parcel information. GIS is the county’s map system. Use a map to help locate the land; get help if the boundary is uncertain rather than treating a map line as a measured survey.
Active listings show your competition. Keep them on a separate sheet from completed sales. A seller may ask for more than a buyer will pay, and a listing may change before it closes.
6. Choose a Selling Plan You Can Compare
An agent can help gather sales, set a price and handle buyer questions. Ask about their land experience, marketing plan and fees. If you sell yourself, plan for photos, calls, visits and help with the contract and closing.
A direct buyer is another option. Ask for the price, costs, conditions and target date in writing. For any offer, compare the money you keep after your costs and balances paid from the sale. Our land offer worksheet helps keep those terms together.
Before spending on improvements, gather clear papers, directions and photos. Ask what work would matter to likely buyers. If you’re helping settle a loved one’s estate, start with the papers you have and ask the closing professional which signatures are needed.
Our Whitman County land selling guide covers more sale steps. If you’d like a direct offer to compare, tell Reelvest about your land. You decide whether it fits.
Questions About Whitman County Land Value
Is my tax value the right asking price?
It’s useful background, not a guaranteed sale price. Check the year and what property is included. Compare recent completed sales of similar land before setting an asking price.
What is REETSifter for?
The Treasurer’s page labels it Excise Affidavits Lookup. Those transfer records can help with sale research. Still check the parcel, included property and nature of the transfer before using a price.
Can I see a full recorded deed without registering online?
The county says Public Login shows document summaries and full online documents require registration. You can call the Auditor’s Office about another way to get a copy and ask about any cost.
Should I use one price per acre for a farm and a small lot?
No. Size, access, services and likely use can differ. Compare each tract with land a buyer would consider as an alternative.
