How to research land before buying: the free tools I use
You need five free sources and about an afternoon: the county assessor, the county recorder, the FEMA flood map, satellite imagery, and the subdivision's own recorded rules. Between them you can answer most of what matters on a rural lot without paying anyone or leaving your desk.
The question people usually ask is which platform is best. The useful answer is that there is no platform, there are counties.
Why there is no single platform for US land data
Land records in the United States are held at county level. Each county assessor keeps its own roll, each county recorder keeps its own books, and neither of them was designed to talk to anything outside the courthouse.
Commercial platforms sit on top of that. They pull county data, normalise it, draw it on a map and charge for the convenience. That convenience is real. What it is not is a separate, better source. Every platform inherits the county's lag, the county's typos and the county's gaps, and adds a layer where you can no longer see which is which.
So the rule I work by is simple. Use the aggregator to find things quickly. Confirm anything you are going to rely on at the county.
How to research land before buying, source by source
Five passes, in this order, because each one produces the key the next one needs.
| Pass | Source | What it gives you | What it cannot give you |
|---|---|---|---|
| 1 | County assessor | Parcel number, legal description, acreage, assessed value, owner of record, tax bill | Anything about condition, and it lags the deed |
| 2 | County recorder or clerk | The deed, the recorded plat, recorded easements and instruments | Rights created by use rather than by writing |
| 3 | FEMA flood map service centre | The mapped flood zone the lender will ask about | Whether this particular lot drains after heavy rain |
| 4 | Satellite and aerial imagery | Tree cover, cleared area, road surface, neighbouring use | Current condition, since imagery is often a year or more old |
| 5 | Recorded bill of assurance for the addition | Minimum dwelling size, use restrictions, what may be built | County level permitting, which is a separate call |
Pass one is where everything starts. For Izard County, Arkansas the assessor record is public and free at actDataScout. Search the parcel number and read off the legal description, because plats and recorded instruments are filed by legal description and not by street address. On one of my lots the mailing address is on Pavilion Lane, the area is known locally by a third name, and the legal description is Tract D, Lot 3, Block 15. Only the last one opens the next door. I unpacked that in how to read a plat map.
Pass two is the deed and the plat. My first parcel's deed was signed on April 15, 2026 and recorded on April 28, 2026 in Book 2026, Page 6725 of the Izard County record. Ten minutes of reading, and it is the document that decides what you are actually buying.
Pass three takes five minutes and answers a question your lender will ask before you do. The detail, including what the map genuinely does not settle, is in how to check if land is in a flood zone.
Pass four is imagery, and the trap is date. A photograph that looks like a cleared lot may be showing you 2023. Check the imagery date before you plan a driveway around it.
Pass five is the one nobody mentions in the forum threads and the one that decides what you may build. Three of my additions carry three different minimum dwelling sizes: 1,100 square feet in North Shore, 1,000 in Spring, 550 on Tract D. Same town, same county. No mapping platform shows that, because it lives in a recorded document rather than in a data layer.
What five free passes still leave open
Two things, and I would rather be blunt about them than sell a checklist as a guarantee.
The first is timing. The assessor updates from the county recording rather than from the closing, so there is a lag between owning a parcel and appearing as its owner. One of my lots still showed the seller's name at the assessor after the sale, which reads alarming until you check the recorder and see the deed sitting there. A mismatch is a question. The deed is the answer.
The second is the ground itself. Slope, drainage after a heavy week, what the access road is like in winter, whether the lot next door stores three dead vehicles. None of that is a record. I bought all seven of my Izard County parcels remotely and I am not going to claim documents closed that gap for me, because they did not. What I did instead is in buying land sight unseen.
Do you need a paid tool for one purchase?
For a single lot, my answer is no, and I say that as somebody who sells lots.
Everything above is public and free. The whole sequence costs an afternoon, and the two calls it may take to the clerk's office are usually the fastest part. Paid data tools earn their money when the constraint is volume, when you are filtering thousands of parcels and need speed more than certainty. That is an acquisition problem, not a buyer's problem.
If you want to run the five passes against a real parcel rather than a hypothetical one, every lot page on this site prints the parcel number next to the legal description, for example the Ranchview Road lot. Take the number, go to the county, and check me. The rest of the pre purchase sequence is in the rural land due diligence checklist.
FAQ
What is the best platform for researching US land data?
There is not one. Records are held county by county, so the assessor and the recorder for that county are the primary sources. Commercial platforms repackage the same records with better maps, and inherit the same lags.
How do I look up land records by parcel number?
Start at the county assessor. In Izard County, Arkansas that is public and free at actDataScout. Read off the legal description, then use it at the recorder for the deed, the plat and any recorded instruments.
Can you research land properly without visiting it?
You can settle ownership, boundaries, easements, flood zone, subdivision rules and taxes from documents. Slope, drainage and the state of the road are not documents. Treat that half as unknown until somebody stands on the lot.
Are paid land data tools worth it?
For one purchase, usually not. The public sources cover a buyer's questions and cost an afternoon. Paid tools solve volume, which is a seller's or a wholesaler's problem.
Why does the assessor still show the previous owner?
The assessor updates from the county recording rather than from the closing, so a gap is normal. Check the deed at the recorder. That is the record that settles ownership.
Before you buy
Get the parcel number first. Everything else in this post is downstream of it, and every one of those five sources is free. If a seller cannot give you a parcel number, you have already learned something.
This is not financial or legal advice. County records, mapping data and subdivision rules vary by parcel and change over time. Confirm the assessor record, the deed, the plat and the bill of assurance with the Izard County assessor and clerk, and have your own attorney review anything you sign.
