Everything you need to verify before closing on raw land — because you can't see problems through a window.

When you buy a house, the inspection tells you what's wrong. When you buy raw land, silence is the status quo — and that silence can cost you thousands. Raw land transactions carry unique risks precisely because there's no structure to hide behind. A cracked foundation signals a problem; bare dirt signals nothing at all. That asymmetry is why due diligence on land isn't optional — it's the entire game.

Why Due Diligence Matters More for Land

Residential buyers get mortgage contingencies, home inspections, and appraisal requirements that collectively surface most major problems before closing. Raw land buyers enjoy none of those safeguards. Land loans typically don't require appraisals in the traditional sense. There is no structure to inspect. And because land transactions move more slowly and attract fewer buyers, sellers are less accustomed to negotiating repairs or credits.

The result: a raw land purchase can look clean on paper and still leave you holding a parcel you cannot develop, sell, or access. A 2021 survey by the American Land Surveyors Association found that over 30% of disputed land transactions involved boundary or title issues that a proper due diligence review would have surfaced beforehand.

Title Search and Chain of Title

Start with the title. Hire a title company or real estate attorney to conduct a full title search. You want to know:

Request the seller's title commitment or existing title policy, if one exists. This document identifies exactly what the title company is willing to insure against — and what it is excluding. Exclusions are your warning signs.

Plat Survey vs. Boundary Survey

Do not confuse a plat survey with a boundary survey. A plat survey — often on file with the county — shows how a parcel was subdivided and carved out of a larger tract. It is drawn from public records, not from physical measurement. A boundary survey is a professional surveyor's physical examination of the land, with iron pins placed at each corner based on on-the-ground measurements.

If the county plat shows your north boundary as 300 feet but the adjacent landowner has been mowing up to what they believe is the line, you need a boundary survey before closing. The cost — typically $500 to $3,000 depending on terrain and parcel size — is trivial compared to a boundary dispute that ends up in litigation.

Zoning and Permitted Uses

Call the county or municipal planning department. Confirm the current zoning designation and what it permits. Raw land may be zoned agricultural, residential, commercial, or forest/recreational — and each designation comes with different rules about building, drilling, logging, and land use.

Ask specifically about:

A parcel that looks like a bargain may have a minimum 5-acre lot size requirement, leaving you unable to build anything meaningful on your 3-acre purchase.

Soil and Percolation Tests

If you plan to build — even a simple septic system — you need to understand what's underground. A perc test (percolation test) measures how fast soil absorbs water, which determines whether a conventional septic system is viable or whether you'll need an alternative wastewater solution.

Many counties require a perc test before issuing a building permit for land without municipal sewer access. Failing a perc test is not uncommon in clay-heavy or rocky terrain. If the land fails, you cannot install a standard septic system without expensive engineering alternatives.

Access and Easements

You cannot assume you have the right to drive to your land. Verify legal access — a dedicated right-of-way, easement, or public road frontage. If the only access is over a neighbor's property, you need a formal easement agreement recorded in the chain of title. Unwritten, informal access arrangements are legally fragile and often unenforceable.

Utilities Availability

Call the utility companies. Ask about the nearest points of connection for electricity, water, and gas. Rural parcels may be miles from the nearest power line, and extending service can cost $10,000 to $50,000 depending on terrain and distance. If the property has no nearby municipal water, you will need a well — and that requires a water table test and, in many states, a registered water well contractor.

Environmental Concerns

Check FEMA flood zone maps (floodprep.com or the FEMA Map Service Center). Check the National Wetlands Inventory (fws.gov). A parcel in a flood zone or wetlands area faces severe restrictions on development and may require expensive mitigation before any construction can begin. Your lender may also require flood insurance as a condition of any financing.

HOA, Covenants, and Deed Restrictions

Even raw land can have a homeowners association and restrictive covenants. If the subdivision was recorded with deed restrictions, those restrictions run with the land — meaning they bind you and all future owners, not just the current seller. Review any CC&Rs carefully before purchasing.

Final Walkthrough Checklist

Before closing, physically walk the property. Bring a printed copy of the plat survey. Verify that:

Due diligence on raw land is not glamorous. It requires phone calls, document reviews, site visits, and patience. But it is the process that separates successful land investors from those who discover, months after closing, that their dream property cannot be developed, accessed, or sold. Treat every parcel as guilty until the records prove otherwise.
