Start with recent sales of land like yours. Match the location, size, access and what a buyer can use the land for. Then compare the whole sale price. Your tax value and nearby asking prices can help you ask questions, but neither tells you what a buyer will pay today.
1. Find Your Land in the County Records
Grab your tax statement or an old deed. A deed is the paper that describes the land and names its owners. Write down the address, tax lot number and county account number if you have them. Vacant land may not have a street address.
Open the county’s property values and improvements page. It links to InterMap, the county’s property map. Search by address, tax lot ID or R number. At your land’s location, look under Additional Information for Assessment & Taxation Information.
The county says this report includes property details, sales and deed information, assessed values and improvements. Save the record or take a screenshot. Check that you found your land, rather than a nearby house with a similar address.
- Write down the acreage. If your deed, survey and tax record show different sizes, keep all three numbers. Ask which area is included before using a price per acre.
- Look for buildings. A sale with a house, shop or barn may be a poor match for your bare land.
- Keep the sale date and deed reference. They help you check whether two results are one sale shown twice.
Missing a document? Start with the land record you can find. You don’t need a perfect file to ask a local land agent or closing company for help.
2. Know Which Tax Value You’re Looking At
Oregon property records can show more than one value. Two numbers matter when you start your price research:
- Real Market Value, or RMV: the assessor’s estimate of what the property would sell for on January 1 for that tax year. Check the year and whether the number includes buildings.
- Assessed Value, or AV: the value used to work out property taxes. It can be lower than the market value.
The county’s property assessment explanation describes how these values work. A low assessed value does not mean you should sell for that amount. The market estimate also has a date. Use recent, similar land sales to help choose an asking price now.
For farm or forest land, also check whether a special tax program applies. These programs can change the tax value. More on that below.
3. Choose Sales a Buyer Would Compare With Yours
A small lot with water and sewer nearby answers a different need from a large field or wooded hillside. County-wide averages mix those needs together. Look for a few sales that fit your land.
Use the county record to check a sale you find. A local agent who sells land can help find recent completed sales and explain the differences. Online listings help show your competition, but an asking price is only what the owner hopes to get.
- Location: Start nearby. Compare similar road access and surroundings, rather than treating every Washington County address as the same market.
- Size and shape: Match smaller lots with smaller lots, and larger tracts with larger tracts. A narrow strip may be harder to use than a wider piece of the same size.
- Access: Check how a buyer would reach the land. A visible track is useful information; written road rights are another part of the question.
- Water and other services: Note what is already on the land, what is nearby and what is still unknown. A water line by the road is not the same as a confirmed connection.
- Allowed use: Compare land with similar uses. Don’t price a field as ready-to-build house lots without checking that idea.
- Buildings and land condition: Separate bare land from sales with a home. Note steep ground, wet areas, trees, cleared space and old improvements.
Try to explain each match in one sentence: “This sale is useful because it has about the same size, road access and allowed use.” If you can’t, keep looking.
4. Clear Up the Questions That Change the Price
You don’t have to order every possible report before selling. First find out what buyers are likely to ask. Clear answers can help them make an offer with fewer guesses.
One important local detail: a tax lot number does not, by itself, prove that the land is a separate lot that can be built on. The county’s map questions page explains that tax lots and legally created lots are different. If a buyer wants a home site, ask the planning office for the land’s location whether that use is allowed.
If the land has a creek, wet area or wooded habitat, save any reports you already have. Washington County has natural resource maps and help. Its urban-area lookup tool covers areas outside city limits; rural land uses different maps and rules. For county planning questions, call 503-846-8761. Give the tax lot number and ask which office can answer for your land.
A mapped feature is a reason to ask a focused question, not a reason to call all the land unusable. Ask what it means for the buyer’s likely use. Keep the answer with your selling notes.
For road rights or unclear boundaries, share the deed and any survey with the closing company. County maps are useful starting points. They aren’t a substitute for checking the papers that apply to your land.
5. Check Farm or Forest Tax Programs Before Comparing Offers
Does your land have reduced taxes because it is used for farming or forest? Ask whether the next owner’s plans could change that treatment.
The county’s farm and forest tax page explains these programs and how to request an estimate of taxes if land loses its qualifying status. For questions, call 503-846-8826.
Ask: “Is my land in one of these programs? What changes could end it? Could extra taxes be due, and who would pay them in this sale?” Bring the answer to the closing company before you agree to the terms. A sale alone does not tell you what the tax result will be.
This matters when comparing offers. A higher headline price may not leave you with more money if you also take on a larger bill.
6. Put Your Best Matches on One Simple Sheet
Make one row for your land and one for each useful sale. A notebook works fine. Use these headings:
- Location and county account or tax lot number.
- Acres and any buildings included.
- Sale date, completed price and deed reference.
- Road access, water and other services.
- Allowed use and important differences.
- Why this sale is a good match—or why you left it out.
Count each sale once. Two listings with similar addresses, acreage and dates may point to the same land. Match the account, tax lot and deed before treating them as two separate sales. Also check whether the price bought one parcel or several together.
A simple example: If a 10-acre tract sells for $200,000, the price is $20,000 per acre. These are made-up numbers to show the math, not a Washington County sale or price estimate. You can’t assume a nearby 5-acre tract is worth $100,000. It may have different access, services or allowed uses.
Use your closest matches to discuss a reasonable price range. If you have very few matches, say so. An agent or appraiser who works with local land can help you decide how much weight to give each sale.
7. Compare the Money You’d Keep and the Work Ahead
Once you have a price range, choose how you want to sell. You can list with an agent, sell it yourself or compare a direct buyer’s offer. Each choice can fit a different need.
- An agent: Ask about their recent land work, price advice, fees and plan to find buyers.
- Selling it yourself: You handle the listing, questions and showing arrangements. Use a closing company to help with the papers and closing.
- A direct offer: Ask for the price and all the terms in writing. Find out what checks the buyer still needs to do and who pays each cost.
Compare the money you expect to keep after fees, loan payoffs, taxes and agreed costs. Then compare the time and work involved. A large asking price is not a completed sale, and an offer can still have conditions.
If you’d like an offer from Reelvest to compare, tell us about your land. You can keep researching or choose another way to sell. For more preparation steps, read the Oregon land seller guide.
What to Gather Before You Ask for Price Advice
Put your tax record, deed, recent photos and any survey in one folder. Add a short note with the acreage, how to reach the land and what you know about water and other services. Mark unanswered questions as “not sure.” That is more useful than guessing.
If you’re handling inherited land or helping settle a loved one’s estate, share the papers you already have with the closing company. They can help work out who needs to sign and what else is needed. You don’t have to sort it all out before asking for help.
Your goal is a clear picture of what you’re selling, a few useful price comparisons and offers you can weigh side by side. Start with those pieces and fill the gaps as you go.
Questions About Washington County Land Value
Is there one price per acre for Washington County land?
No. Size, location, road access, allowed use and services can change the price. Use recent sales of similar land rather than one county-wide number.
Should I use my assessed value as my asking price?
Use it as a tax record, not a ready-made asking price. Oregon assessed value can be below market value. Check the dated Real Market Value and recent similar land sales too.
Where can I find Washington County property and sale records?
The county’s property values page links to InterMap. Search by address, tax lot ID or R number. Look under Additional Information for Assessment & Taxation Information.
Does a tax lot number mean I can sell it as a home site?
No. The county explains that a tax lot and a legally created lot are different. Ask the planning office for the land’s location whether the proposed home use is allowed.
Does farm or forest tax treatment affect a sale?
It can affect the costs and terms. Ask the county whether the land qualifies, what changes could end the program and whether extra taxes could be due. Review the answer before agreeing who pays.
How do I avoid counting the same sale twice?
Check the county account or tax lot, deed reference and sale date. Similar listing addresses alone do not prove two separate transactions. Check whether one price covered several parcels.
Do I need every document before asking for an offer?
No. Start with your land’s location and the records you have. Tell the buyer which details you know and which you are still checking.
Can I compare a Reelvest offer with other ways to sell?
Yes. Compare the price, costs, conditions and expected timing with an agent listing or selling it yourself. You choose the option that fits you.
