Raw land doesn't come with disclosures the way a house does. There's no seller's disclosure statement, no inspection report, no previous owner to call with questions about the water heater. When you buy undeveloped land, you're buying what you can verify — and that makes due diligence the most important step in the process.
Unlike a home purchase where the bank handles much of the verification through appraisals and title insurance requirements, owner-financed land transactions often skip the institutional guardrails. The seller lists, you apply, you close. Between application and closing is where due diligence lives — and it's your responsibility.
The good news: land due diligence is systematic. Work through these 10 items before you sign anything, and you'll catch the problems that would otherwise become expensive fixes after you've already handed over your down payment.
1. Title Search
A title search confirms who legally owns the property and whether there are any claims against it. A cloud on the title — a lien, a disputed boundary, a conflicting deed — can make the land uninsurable and unsellable.
Why it matters: If a previous owner's debt was secured against this land, the creditor may have a claim. Without a clean title, you don't really own what you think you bought.
How to check: Hire a title company or real estate attorney in the county where the land is located. A basic title search typically costs $200–$500. Ask for a preliminary title commitment — it shows what the title company is willing to insure and what exceptions they're flagging.
2. Property Survey
A survey establishes the physical boundaries of the parcel. Without one, you don't know where the property actually ends and a neighbor's land begins.
Why it matters: Land boundaries are commonly disputed, especially in rural areas with old deeds and no fence lines. A neighbor who's been using a strip of your parcel for 20 years may have a claim to it under prescriptive easement laws.
How to check: Commission a boundary survey from a licensed surveyor in that county. Ask specifically about encroachments — any structures, fences, or improvements that cross the property line. Expect to pay $400–$1,200 depending on parcel size and terrain. If the seller already has a recent survey, get a copy and verify it matches the legal description in the deed.
3. Zoning & Land Use
Zoning determines what you can legally do with the land — what structures you can build, whether you can camp on it, subdivide it, or run a business.
Why it matters: Buying 10 acres in an agricultural zone when you planned to run a small event venue is a problem you can't solve after closing. Zoning restrictions can kill a land-use plan entirely.
How to check: Call or visit the county zoning or planning office. Provide the parcel's tax ID or legal description and ask for the zoning designation and any applicable overlays (conservation easements, flood zones, historic districts). Most counties have this information online.
4. Easements & Encumbrances
An easement is a legal right for someone else to use a portion of your land — a utility company running power lines, a neighbor accessing a road that cuts through your property, a drainage district maintaining a ditch.
Why it matters: An undisclosed easement can make land nearly unusable for its intended purpose. A utility easement across the middle of your building envelope is a layout problem you'll wish you'd known about before closing.
How to check: The title search should surface recorded easements, but verify them independently by reviewing the plat map and asking the county recorder about any additional recorded instruments. Ask the seller directly: "Are there any easements, rights-of-way, or shared-access agreements on this parcel?"
5. Soil & Perc Test
A soil analysis and perc test (percolation test) tell you whether the ground can support a septic system. If you're planning to build or camp long-term, this is non-negotiable.
Why it matters: Not all soil can accommodate a standard septic drain field. Clay-heavy or rocky ground may require an engineered system that costs $15,000–$30,000. In some cases, septic isn't feasible at all.
How to check: Contact a licensed perc test provider or soil scientist in the county. The test involves digging holes and running water through the soil to measure drainage rate. Results typically take 1–2 weeks. Your county health department can provide a list of certified testers. Cost: $300–$600.
6. Flood Zone Status
FEMA designates flood zones based on historical flood data. If your parcel falls in a high-risk zone (Zone A or AE), federally backed lenders will require flood insurance — and it can be expensive in rural flood-prone areas.
Why it matters: Flood insurance on rural land with no structures can still be required if any part of the parcel is in a flood zone and you're financing through certain channels. For raw land, this cost is ongoing and often overlooked.
How to check: Look up the parcel on FEMA's Flood Map Service Center (msc.fema.gov) using the property address or GPS coordinates. Check the county property appraiser's site — many list flood zone designation. If the property is partially in a flood zone, ask a local flood insurance agent for a premium estimate before you close.
7. Road Access
Legal road access means there's a legally documented way to enter and exit your property — either a public road frontage, a private road you own, or a deeded easement granting access to a public road.
Why it matters: Landlocked parcels exist. If the only access to the land runs through a neighbor's property and there's no formal easement, you're dependent on their goodwill — and that can change. "Prescriptive access" is a legal concept, but it requires years of documented use and court action to establish.
How to check: Ask the seller to provide documentation of access. Confirm with the county road department whether the parcel has frontage on a public road. If access is via a private road, confirm the road is maintained and that you have legal right to use it. A real estate attorney can verify access rights from the chain of title.
8. Utilities Availability
For rural parcels, "utilities" may mean none at all — no electric grid connection, no county water, no sewer. Understand what's actually available before you factor it into your budget.
Why it matters: Running electric service to a rural parcel can cost $10,000–$30,000 depending on distance from the nearest transformer. If county water isn't available, you're looking at $5,000–$15,000 for a well. These costs are real and often underestimated.
How to check: Call the county utility or electric co-op and ask about the nearest hookup point and estimated cost to serve the parcel. Ask neighbors whether they have wells and what depth they drill to. For septic viability, see item 5 above. Confirm cell signal by checking coverage maps from your carrier on-site or with a neighbor.
9. Property Taxes & Outstanding Liens
Unpaid property taxes create a lien on the land that survives the sale. The county can foreclose on a tax lien — even after you've purchased the property if the seller had outstanding obligations.
Why it matters: In many states, property tax liens have priority over all other liens, including mortgages and seller financing. You could pay the seller, and then discover six months later that the county has a claim against the property for three years of unpaid taxes.
How to check: Look up the parcel on the county property appraiser's website and check the tax status. Confirm whether there are any outstanding delinquent taxes. Ask the seller for a tax certificate from the county showing current status. If there are back taxes owed, negotiate for the seller to pay them at closing or reduce the purchase price by that amount.
10. Environmental & Contamination
This covers a range of potential issues: old underground storage tanks, illegal dumping, chemical storage, asbestos from prior structures, or proximity to contaminated sites that could affect groundwater or require cleanup.
Why it matters: Environmental contamination can be expensive to remediate and, in extreme cases, can make land unusable. If the parcel was previously used for industrial purposes, farming with heavy chemical use, or had structures with old heating oil tanks, these are issues you want to know about before you own them.
How to check: Search the EPA's ECHO database and your state's environmental agency database for the parcel address. Look for any recorded contaminations or cleanup orders. Drive the parcel and surrounding area — look for old tanks (metal tanks partially buried), piles of debris, or staining that suggests dumping. Ask the seller directly about prior use. If anything raises concern, commission a Phase I Environmental Site Assessment from a licensed environmental consultant ($800–$2,000).

The full cost of due diligence on a raw land parcel typically runs $1,500–$4,000 depending on location, parcel size, and what the seller has already provided. That's a meaningful investment — and it's the best money you'll spend before closing on any land purchase. If a seller is reluctant to allow due diligence, that's a signal worth paying attention to.
