Your land’s tax value is one clue, but it isn’t a current offer. Start with similar land that has sold, then check the acreage, road access and home-site records for your tract. Chatham County links a comparable-sales tool and public records you can use. The most useful matches have a similar use and similar work still needed.

Start with Chatham’s comparable-sales and parcel tools
The Appraisal Division links Comper to locate comparable sales, plus tax records and a land map. A comparable sale is a sold property you can use to judge a similar one. Start with land-only sales when your tract has no buildings.
Save the sale date, price and land IDs. Check the acres and what changed hands. One deed may cover several lots or include a house. Don’t divide the full deal price by one lot’s acres and call it a land price.
Keep asking prices in a separate list. They show what owners hope to get. A completed sale shows what was paid, but it still needs a close look before you use it as a match.
Read the date behind the tax value
Chatham’s Appraisal Division says its most recent countywide tax reappraisal took effect January 1, 2025. Reappraisal means updating values across the county for taxes. The office says that schedule used sales from 2023 and 2024.
That date matters when you price land today. The tax record does not promise what a buyer will pay now. Check more recent useful sales and the land’s current condition. Ask the Tax Office about a record that includes the wrong acres or buildings.
If you see two different values, first ask what each includes and which date it uses. A land value and a total value with a house are different numbers. Keep the tax figure labeled in your notes so it doesn’t become a supposed sale price.
Use the recorded survey when acreage records differ
The Land Records Division links deed and plat searches. A plat is a survey map. Its guidance says a changed-acreage survey must be recorded before the county updates the map and tax record. Acreage changes take effect for taxes on January 1 of the next year.
If you had a recent survey or split, gather the recorded papers and tell the buyer why an older tax bill may differ. Ask Land Records what has been updated. Ask the closing team which description the sale agreement should use.
Keep each land ID on the offer sheet. If you’re selling only part of a tract, make that clear before comparing it with a sale of the whole property. A proposed split and a recorded lot are different things.
Know which septic approval you actually have
Chatham’s septic permitting guide describes separate steps under its public option. Septic treats household wastewater on the land. The Improvement Permit follows a suitable site and soil review. Construction Authorization is the step for installing the system. The Operation Permit follows installation and approval.
Don’t describe all three as “a perc test.” That phrase is often used loosely for soil checks. Tell the buyer which document you have and what home plan it covers. Ask the office about its date, conditions and any layout change.
A soil review alone doesn’t show that a working system is in place. For a sale match, compare the same stage of readiness. Ask about costs still needed rather than assuming a permit removes all site work.
Find old well and septic papers before guessing
The county’s wastewater and septic page links a public-records request for well and septic permits. It also lists an existing-system approval option. Start there if papers are missing.
Gather the land ID, address if there is one, and any old owner or permit details you have. Ask whether the record fits the exact tract and planned home. If no record has been found yet, say that. It is different from proving that no record exists.
Put the home, driveway, well and septic areas on the same sketch when discussing the plan. Nearby utility service does not prove a connection is available to this parcel. Get a provider’s answer and estimate before counting it as ready.
Choose sales that fit the same buyer and use
A wooded recreation tract and a home lot can appeal to different buyers. Compare road rights, usable layout, water and the septic stage, then look at size and location. A nearby house sale may say little about a vacant tract.
Try writing a one-sentence reason for each match: “Both have road access and an approved three-bedroom home site, but mine still needs the system installed.” Use only facts supported by the records. If a key fact is unknown, leave it marked unknown.
If you can’t find enough close matches, ask a local land agent or appraiser for help. A broad price range may be more honest than a precise number built from unlike land.
Compare the price, open checks and money you keep
- Land being sold
- Land IDs, recorded acres, deed and plat references.
- Sold-land evidence
- Sale dates, prices, buildings and reasons the parcels fit yours.
- Home-site records
- Exact septic stage, planned use and questions still open.
- Sale terms
- Review deadlines, who pays for checks and what must happen before closing.
- Money you keep
- Offer less seller costs, loans and unpaid taxes.
Ask whether the buyer’s offer depends on a new site check and how long that review may take. Put the answer in the agreement. You don’t need to buy a new test before asking which records a buyer needs.

Questions About Chatham County Land Value
Is my Chatham County tax value a current sale price?
No. The county’s latest general reappraisal took effect January 1, 2025. Compare useful completed sales and the land’s current features before choosing a price. Keep the tax value labeled separately.
Where can I find comparable sales in Chatham County?
The Appraisal Division links its Comper sales tool. Check the sale date, land IDs, acres and what the price included. Choose land with similar access, use and home-site readiness.
Is an Improvement Permit the same as an installed septic system?
No. Under the county’s public process, site approval, permission to install and approval after installation are separate steps. Show the buyer the exact document you have and ask Environmental Health about its current use.
Why might my tax bill show different acres from a recent survey?
Land Records explains that the survey must be recorded before map and tax updates. Changed acres take effect for taxes the following January 1. Share the recorded papers and ask the office to check the difference.
