Match the sale to the parcel as it existed when sold. Guilford County's map and tax bill can lag behind a split, and its GIS map doesn't draw easements. Check the deed and survey before you decide that two pieces of land are good price matches.
Start With Current County Links
The Guilford County GIS Online Services page links to the data viewer, Parcel Research, appraisal records and sales-research resources. GIS means an online map with information about land. Save your parcel ID, listed acres and location before you collect sale prices.
The older Property Sales Research Tools link currently leads to the county's 2026 Reappraisal page. That page links to Comper Citizen for sale comparisons and to the property listing system. Use the current county links rather than assuming an old bookmark opens the same tool.
A reappraisal is an update to property values used for taxes. Guilford says its 2026 values took effect on January 1, 2026. Keep the value date with your notes. A tax value and a current selling price answer different questions.
Check a Split Parcel and Its Access Papers
The county's Mapping and Ownership Transfer page says tax bills reflect property as of January 1. A later split or combination is reflected in the following year's bill. Newly recorded documents can also take time to appear online.
The same page says GIS lines are for information and may shift against aerial images. It also says easements are noted in land records but aren't mapped. An easement is a right to use part of someone else's land, such as a route to reach your lot. An empty spot on the map doesn't prove there is no written access right.
- Check the parcel ID on the tax record and deed.
- Note any split or combination and its date.
- Read the sale deed for all land included at that time.
- Gather the survey and any written access document.
- Ask Land Records about a mismatch instead of choosing the acreage that gives the nicest price per acre.
Compare the Same Land, at the Same Stage
For example, a seller may own a new two-acre piece cut from a larger tract. The old tax bill still describes the larger tract. A past sale price for the whole tract won't show the value of the new two-acre piece. Keep the old parcel, new parcel and date of the split separate.
Then compare what a buyer could actually use. A road-front lot with confirmed services may not be a close match for land reached by a shared lane. Write down whether road entry, water, sewer or septic plans have been checked. Septic is the waste system used where a sewer isn't available.
- Land included: One parcel or several? Before or after a split?
- Added value: Did a house, barn or other building come with it?
- Use: Does the buyer need a home site, farm ground or another use?
- Access: Is the road route backed by the right papers?
- Open work: What checks and costs remain before the buyer can use the land?
Choose a few sales with clear records and useful similarities. If a tax tool suggests a match, review it instead of accepting it automatically. A tool can help find records; it can't explain every difference between two lots.
Keep the evidence beside each price and explain the biggest difference in one sentence. That makes a price discussion easier to follow and helps you spot when you need more help from an agent or appraiser.
A Simple Sheet for Comparing Sales
Make one row for each deal you can check. Keep asking prices in a separate list; they show what a seller wants, not what a buyer paid.
- Land ID and deed number
- Check that you're counting the same parcel and transfer only once.
- Sale date and full price
- Write down where you found them. Leave a blank if you can't confirm them.
- Total acres and what was included
- Note buildings, other parcels, and any separate rights.
- Access, use, and site work
- List the biggest differences from your land.
- Keep or leave out?
- Write a short reason. Choose close matches over a longer list.
How to Work Out Price Per Acre
Divide the checked sale price by the acres included. For example, a made-up sale of 20 acres for $120,000 works out to $6,000 per acre. This shows the math; it isn't a local sale or an estimate for your land.
Use that number only after checking the match. It doesn't show the cost of a new road, the value of a house, or whether your land can serve the same use.
Use Your Research to Compare Your Options
You can use close sales to discuss an asking price with an agent or appraiser. You can also ask a buyer for a direct offer. Compare the price, costs, terms, and work involved. A higher headline price may leave you with less money after those costs.

Questions Sellers Ask
Why does my Guilford tax bill still show the parcel before a split?
The county says bills reflect the property as of January 1. Splits or combinations after that date show in the following year's bill. Check the current deed and ask Land Records about a mismatch.
Does a missing easement on the GIS map mean I have no road access?
No. Guilford says easements aren't mapped, though they are noted in land records. Gather the written access papers and check what route and rights they cover.
Where does the old Guilford sales-tool link go now?
It currently leads to the county's 2026 Reappraisal page. That page links to Comper Citizen and the property listing system. Start with current county links and check the record details.
Can I use a large tract sale to price a piece split from it?
Only with care. The older sale covers the land included at that time. Match the right acres, access, buildings and parcel history before treating it as a useful comparison.
