The Raw Land Buyer's Due Diligence Checklist

Never confuse physical access with insurable legal access. If the two-track dirt road traverses your neighbor's timber plot without an expressly recorded, perpetual easement appurtenant running with the land, that neighbor can legally erect an iron gate tomorrow morning and there is nothing a title policy will do about it.

Prescriptive access rights — established by years of continuous open use — are explicitly excluded from standard title insurance policies. CLTA and ALTA title policies both carry Schedule B exceptions for matters that would be shown by a survey or matters of which a buyer had notice. An appraiser who walked the road is not the same as a recorded easement. If the seller points to "we've always used that road," terminate the deal or require a recorded easement as a purchase condition, full stop.

The fix is a boundary survey with access easement determination, or a quiet title action — either route costs time and money the seller should bear before you close. Require this as a non-waivable contingency.

Do not accept a perc test older than three years — state sanitary codes change, and a test conducted under 2019 regulations may not meet 2026 requirements for system design. More critically, many sellers present a single perc hole result from a dry-August test. That is not the standard.

A proper evaluation requires two 8-foot backhoe excavation pits timed during the wet season — when the seasonal high water table is at its worst. Saturated clay loam soils or shallow bedrock shallower than 48 inches below the absorption field will disqualify standard gravity-fed drainfield systems. You'll be looking at an engineered mound system, an aerobic treatment unit, or a drip-irrigation subsurface dispersal field — any of which runs $18,000 to $35,000 more than a conventional system.

In some counties, a soil scientist or licensed site evaluator must conduct the morphological soil examination in addition to the perc test. Budget for the full assessment, not the shortcut. Granite caprock at 36 inches has ended more rural homestead dreams than any other single soil condition.

In most Western states, the mineral estate is legally dominant over the surface estate. If an oil company, railroad, or timber corporation reserved mineral rights in 1941 — or 1908 — that reservation travels with the deed in perpetuity. The mineral rights owner holds implied legal authority to enter your property, construct access tracks, and operate drilling equipment on your surface without requiring your consent or compensating you beyond a narrow "reasonable use" standard.

The phrase "severed minerals" appears nowhere on MLS listings and is never volunteered by sellers. You discover it in a 60-year mineral deed run — a title search specifically examining the chain of mineral title going back six decades. Major mineral severances were common between 1900–1960 when railroads, federal land grants, and oil companies purchased surface parcels while explicitly reserving subsurface rights. A parcel that has changed hands twelve times since 1940 may still carry a 1938 Standard Oil mineral reservation.

If minerals are severed, request a Surface Use Agreement from the mineral rights holder before closing. This is a negotiated document limiting where and how subsurface access may be exercised. It does not guarantee protection but provides contractual recourse if mineral operators damage improvements.

"Power at the road" is the single most misunderstood phrase in rural land listings. It typically means a high-voltage distribution line passes along the road right-of-way — not that a service drop and meter base are anywhere near your parcel. Installing a single pole-mounted transformer and 200-amp service drop from a roadside distribution line often runs $6,000–$12,000 before you pull the first permit.

If the parcel sits 600 feet off a county road, or the distribution line must be extended to reach your building site: overhead single-phase extension runs $12,000–$25,000 per quarter-mile. Underground trenching through open soil averages $18–$35 per linear foot. Through granite substrate — common in the Sierra Nevada, Colorado Rockies, and Pacific Northwest ranges — trenching may require explosive blasting, pushing costs to $65+ per foot.

Call the serving rural electric cooperative directly with the parcel APN and ask for a "new service extension estimate." They will tell you what the extension will cost under their current tariff schedule. Do not assume, and do not rely on the seller's estimate. Solar-plus-battery as a substitute must also be modeled at full panel + inverter + battery bank cost — often $35,000–$70,000 for a full residential off-grid installation.

Water rights law in the United States splits along a geographic fault line at roughly the 100th Meridian. Understanding which doctrine governs your parcel determines whether the creek running through your property is a resource or an irrelevance.

Western states (17 states from the Dakotas westward): Prior Appropriation. The governing principle is "first in time, first in right." Water rights are issued as adjudicated decrees by the state engineer's office, tied to a priority date and a specific beneficial use. A stream that bisects your parcel may belong entirely to a rancher upstream who obtained a water right decree in 1887. In a drought year, that 1887 decree calls first, your parcel calls last, and "last" may mean zero water. Adjudicated basins — particularly in Montana's Clark Fork drainage, Idaho's Snake River basin, and most of Colorado — are fully allocated. New rights are simply unavailable at any price in fully appropriated systems.

Eastern states (east of the 100th Meridian): Riparian Doctrine. Landowners whose property abuts a natural watercourse have a right to reasonable use of that water, so long as it doesn't unreasonably interfere with other riparian users. Water rights generally travel with the land rather than being separately deeded. This is meaningfully more favorable for rural buyers — a stream crossing your property in Tennessee is a genuine asset.

Domestic well permits carry state-specific exemptions and caps. Wyoming permits exempt domestic wells to 35 GPM; Idaho limits exempt domestic use to 13,000 gallons per day; Montana's exempt well regime applies below specified depths but varies by basin. In all cases, request written confirmation from the state engineer's office — not from the seller's agent — before treating a well permit as a given.

FEMA flood maps are notoriously outdated — the agency acknowledges a lag of 10 to 20 years between actual floodplain conditions and updated map panels. Zone AE designation means high-risk, mandatory purchase of federal flood insurance on any financed structure. Zone X means low-to-minimal risk. But Zone X in 2004 may be Zone AE in 2026, particularly in river valleys that have experienced watershed development upstream. Pull the current Flood Insurance Rate Map (FIRM) from the FEMA Map Service Center and compare it to recent Google Earth Pro historical imagery, checking for evidence of inundation.

Army Corps of Engineers wetlands jurisdiction is the more dangerous issue for buyers. Under the Clean Water Act, the Corps has regulatory authority over "waters of the United States," which includes not just navigable rivers but seasonal wetlands created by stormwater drainage, isolated prairie potholes, and ephemeral streams in arid zones. A parcel that appears to be dry grassland nine months per year may contain federally jurisdictional wetlands that prohibit fill, grading, or structure placement. Violating Section 404 of the CWA carries civil penalties exceeding $50,000 per day.

A jurisdictional wetland corridor bisecting a parcel can effectively eliminate the buildable envelope entirely. The Army Corps Nationwide Permits (NWP) program allows some minor impacts under categorical approvals, but anything beyond minimal fill triggers an individual Section 404 permit — a multi-year process with no guarantee of approval.

Use the USFWS National Wetlands Inventory mapper and the Corps' Regulatory In-lieu Fee and Bank Information Tracking System as a preliminary screen, then hire a qualified wetlands delineator for any parcel with seasonal water features.

"Agricultural" zoning is not a building permit. In many Western counties, A-1 or AG zoning requires a minimum lot size of 35 acres before a county building permit will be issued for a principal residence. If your 15-acre parcel is zoned A-1 in a county with a 35-acre residential minimum, it cannot be built on without a variance — and variances are discretionary, not guaranteed.

State law and county planning codes operate independently. A state that broadly permits rural residential use may have individual county ordinances that impose stricter setbacks, wildland-urban interface construction standards, or conservation overlay districts. Call the county planning department directly, give them the parcel APN, and ask what uses are permitted by right and what requires a conditional use permit.

CC&Rs (Covenants, Conditions & Restrictions) run with the land, not with the seller. A parcel in a 1972 ranchette subdivision may carry private deed restrictions that prohibit manufactured housing, limit livestock counts, require architectural committee approval, or ban short-term rental use — none of which appear in county zoning records. These are found in the recorded subdivision plat and Declaration of Restrictions at the county recorder. A defunct HOA still has its covenants; the restrictions remain enforceable by adjacent parcel owners even if no HOA board exists to enforce them.

Road associations — separate from HOAs — are particularly hazardous. A private road maintained by a non-incorporated association may assess unpaid road dues as a lien against individual parcels. Confirm whether an active or dormant road association exists and whether any current assessments are unpaid.

The recorded survey on file with the county may be 50 years old. The legal description in the deed may reference corner monuments that no longer physically exist or have shifted. "Paper roads" platted in 1928 subdivisions may have been physically vacated in 1955 but never formally removed from the plat — leaving easement corridors that cross your buildable area on paper.

Public Land Survey System (PLSS) corner monuments — the government brass caps that define section, township, and range corners — shift over time due to frost heave, erosion, and vandalism. A rural parcel described as "the NW¼ of the SW¼ of Section 12" contains the implicit uncertainty of where those section corners actually sit on the ground today. A licensed land surveyor (PLS) can re-establish corners from witness monuments and recorded bearings, but the results sometimes differ from what the seller has been representing.

Do not buy what you can see. Buy what the legal description says — and confirm those two things match. The fence line is almost never on the legal property line. Livestock fences are practical, not cadastral. Neighbors who have used land up to a fence line for 20 years may have adverse possession claims if that fence encroaches on your legal boundary.

A boundary survey is the minimum; for lender requirements and the strongest title insurance position, the ALTA/NSPS Land Title Survey is the gold standard. It locates all easements, encroachments, improvements, and monuments to a standard acceptable to the title insurer. Cost ranges from $2,000 on a small rural parcel to $8,000+ on complex terrain.

A title search examines the chain of ownership going backward in time, looking for gaps, errors, and encumbrances. For raw land — particularly in the American West — a 40-year search is the minimum. The reason: railroad land grant patents, federal homestead acts, and BLM disposal patents from the late 1800s through the 1930s frequently carried mineral reservations, right-of-way grants for future federal projects, and timber easements that were never extinguished. A 20-year search from a typical residential title plant will miss these.

Heirship gaps are common on rural parcels. A landowner dies intestate in 1963; the property changes hands by informal agreement among heirs but is never formally conveyed through probate. The recorded chain breaks at 1963, and subsequent deeds are of questionable validity. A quiet title action may be required to establish marketable title — a process that can take 12 to 18 months.

Read the Schedule B exclusions on your title insurance commitment before closing. Schedule A covers what you own. Schedule B covers what the insurance does NOT insure — and this is where most raw land surprises live. Common Schedule B items on rural parcels include: pipeline easements, power line easements, road easements of record, unrecorded survey stakes, and matters that would be disclosed by a current survey. If a Schedule B item concerns you, ask the title company to insure over it, or require the seller to cure it before closing.

Raw land generates $0 in income while relentlessly consuming capital. The naive analysis looks only at purchase price and ignores the compounding annual cost of simply holding title. Most buyers do not run this math before signing a purchase agreement, and many are surprised when their $15,000 "affordable" parcel costs more to own each year than a financed vehicle.

The components of annual holding cost on raw land: property tax (calculated on assessed value, which on rural land often diverges significantly from purchase price — confirm the actual assessed value and millage rate, not the seller's estimate); loan interest at 9–14% annualized (raw land loans rarely have 30-year terms; expect 5-year balloon notes or 15-year amortizations with 25–35% down payment requirements); road maintenance reserve (shared private roads require annual gravel resurfacing); fire and weed mitigation (many Western counties mandate defensible space and noxious weed control with lien authority for non-compliance); agricultural rollback tax liability (if the parcel previously held a special-use agricultural valuation, changing the use to residential triggers retroactive taxes with interest — sometimes spanning 5 years of back taxes at unexempted rates).

The infrastructure math compounds the holding cost picture. The $15,000 parcel that requires $94,700 in baseline infrastructure — well drilling, engineered septic, private road construction, and power extension — effectively costs $5,485 per usable acre by the time you break ground on a structure. A $120,000 parcel with established utilities and permitted access may represent better capital efficiency by an order of magnitude. Run the full cost model before your earnest money check clears.
