A boundary survey marks your property’s corners and lines and is enough for most cash raw-land purchases; an ALTA/NSPS Land Title Survey adds title research, easements, encroachments, and access detail that lenders and title companies require before insuring a mortgage or removing survey exceptions from a title policy.
What’s the actual difference between a boundary survey and an ALTA/NSPS survey?
An ALTA/NSPS Land Title Survey is a boundary survey with a much longer list of requirements layered on top, not a separate type of measurement. Boundary surveys are governed by whatever standard each state’s licensing board sets, while ALTA/NSPS surveys follow a single national standard set jointly by the American Land Title Association and the National Society of Professional Surveyors, according to Cretelligent.
West Virginia’s rule for professional surveyors states this relationship directly: ALTA/ACSM Land Title Surveys “shall at a minimum comply with the minimum standards for a boundary survey,” according to the West Virginia Board of Professional Surveyors. That is the practical way to think about the two: every ALTA survey contains a boundary survey inside it, plus title research, easement documentation, and whatever additional detail the client asks the surveyor to add.
What does a boundary survey cover, and what does it leave out?
A boundary survey establishes where your corners and lines actually sit on the ground, based on a record search of deeds and a field search for existing monuments, and it typically does not extend to easements, rights-of-way, or encroachments unless you ask for them. Under West Virginia’s minimum standards, a boundary survey requires a record search of current and prior deeds and the descriptions of adjoining land, a field search for controlling evidence, monumentation of new or reestablished corners, and a plat showing acreage, adjoining owner names, and the surveyor’s seal, according to the West Virginia Board of Professional Surveyors.
What it usually skips: a boundary survey “usually does not require the surveyor to identify other types of rights in real property, such as easements or encroachments,” and on its own it does “not provide sufficient details to support title exams for insurance,” according to Cretelligent. For a buyer who just wants to know where the fence line should go, or a seller confirming acreage before listing, that scope is usually plenty.
What does an ALTA/NSPS survey add on top of that?
An ALTA/NSPS survey adds the title, access, and improvement detail a title insurer needs to underwrite the property with confidence, going well beyond the corners and lines a boundary survey covers. It documents “all improvements, easements, rights-of-way, and other elements impacting the ownership of the land,” including utility lines and neighboring improvements, and it is built to give “lenders, title companies, and buyers a consistent, reliable survey product” regardless of which state the land sits in, according to Cretelligent.
The reason title companies push for it comes down to what the survey lets them do with the policy. An ALTA survey “combines a boundary survey by graphically showing and describing the physical outline of the land with the location of improvements, possible encroachments, easements, utilities,” and most lenders “require the title insurer to insure over the survey matters as they exist on the ground,” according to Eagle Title. In practice, that means the survey is what allows the insurer to remove or narrow the standard survey exception in the title policy, rather than leaving that exception in place indefinitely. The American Land Title Association maintains the Minimum Standard Detail Requirements specifically so that title insurers, lenders, and surveyors are working from the same checklist rather than negotiating scope from scratch on every deal.
How much more does an ALTA survey actually cost?
An ALTA/NSPS survey typically costs several times what a basic boundary survey costs on the same parcel, because it adds title-document review and a longer field checklist to the work. A boundary survey on an easily accessible lot of an acre or less commonly runs $400 to $700, while an ALTA/NSPS survey commonly starts around $1,000 and can run $2,500 or more, according to Alliance Land Surveyors. On raw acreage, expect both figures to climb: larger tracts take longer to measure and verify, dense vegetation or rough terrain slows fieldwork, and a missing or incomplete prior survey adds research time before anyone sets foot on the property, according to Alliance Land Surveyors.
| Boundary survey | ALTA/NSPS Land Title Survey | |
|---|---|---|
| Primary purpose | Locate corners and boundary lines | Locate boundaries, plus document title-related risk |
| Standard followed | State/local surveyor board rules | National ALTA/NSPS Minimum Standard Detail Requirements |
| Easements & encroachments shown | Not required unless requested | Required |
| Typical starting cost, small acreage | $400–$700 | $1,000–$2,500+ |
| Who usually orders it | Buyer, seller, or neighbor resolving a line dispute | Lender or title insurer, for extended coverage |
| Can remove the survey exception from a title policy | Generally no | Often, subject to the insurer’s review |
When will a lender or title company actually require the full ALTA survey?
A lender or title company is most likely to insist on an ALTA/NSPS survey when the transaction involves financing and the buyer wants extended title coverage rather than a policy that still carries the standard survey exception. Obtaining an ALTA survey is described as “standard due diligence in a commercial transaction,” and the same source warns that skipping it “can be much more expensive” than paying for it if a boundary or encroachment problem surfaces later, according to Eagle Title. Out-of-state buyers, or a group of buyers who don’t all live where the land sits, are also a common trigger, since an ALTA survey gives everyone the same national baseline instead of relying on whatever local standard happened to apply to the last survey, according to Land Surveyors United.
If your lender hasn’t said the word “ALTA” yet, ask directly rather than assuming a plain boundary survey will clear underwriting. Requirements vary by lender and by how the title insurer wants to handle survey exceptions on that specific policy, so a phone call before you pay for either survey can save you from ordering the wrong one.
Why does raw, unsurveyed land make this decision harder than a house would?
Raw land is more likely than a house to have never been surveyed at all, or to have a survey old enough that the methods behind it are no longer considered accurate, which is exactly the situation an ALTA survey is built to sort out. Vacant land “has either never been surveyed or was surveyed long ago when technologies were far less accurate,” which can leave “boundary, ownership or encroachment issues that are unknown at the time of purchase but could come back to haunt you later,” according to Point to Point Surveyors. The same source notes that for vacant land purchases specifically, “an ALTA survey may also be recommended, if not required,” even outside a strictly commercial deal, because the deeper title and record research is what surfaces problems while you still have time to negotiate or walk away.
That is the practical reason the ALTA-versus-boundary question comes up so often for raw acreage and comes up rarely for a subdivision house: a house sits on a lot that was almost certainly surveyed when the subdivision was platted, while forty acres passed down through a family or bought at a tax sale may never have had a professional set foot on it. The lack of a reliable prior survey is itself a reason a title company leans toward the more thorough option.
When is a basic boundary survey genuinely enough?
A boundary survey is genuinely sufficient when you’re buying with cash, the title company isn’t being asked to remove the survey exception, and your main question is simply where the lines and corners fall. Because West Virginia’s rule and comparable state standards treat the boundary survey as the floor that an ALTA survey builds on, ordering the boundary-only version is not a corner-cutting move when nothing beyond the lines is actually in question, according to the West Virginia Board of Professional Surveyors. That covers a lot of raw-land purchases: confirming acreage before closing, resolving a fence-line disagreement with a neighbor, or supporting a legal description before you record a deed.
Buyers who make cash offers directly to landowners, including AMM Land Sales, typically don’t need a lender-driven ALTA survey, since there’s no mortgage underwriting in the transaction. Title is still confirmed through a licensed title commitment and closing happens through a licensed title company either way, so the absence of an ALTA survey doesn’t mean the absence of due diligence, it just means a different party is doing the underwriting.
How do you decide, and what should you ask before you order one?
Start with the party that’s actually requiring a survey, since that answer usually settles the question for you. If a lender is involved, ask them in writing whether they’ll accept a boundary survey or require ALTA/NSPS certification, and ask the title company whether they intend to remove the survey exception from your policy. If no lender is involved and you just need to confirm legal access, an unclear easement, or where a fence should sit relative to the recorded line, a boundary survey from a state-licensed surveyor is usually the right scope and the right price.
Before you call a surveyor, get answers to a short list of questions, since they determine which product you actually need:
- Is a lender financing this purchase, and if so, do they require ALTA/NSPS certification in writing?
- Does the title company plan to remove the survey exception, or will the policy carry it regardless of which survey you order?
- Is there a prior survey on file, and is it recent enough and complete enough for the title company to rely on?
- Do you plan to build, subdivide, or add improvements that depend on knowing exactly where utilities and easements run?
- Are any of the parties to the deal out of state, and do they need a single national standard instead of whatever the local norm happens to be?
If the answers point to a straightforward boundary confirmation, don’t let a surveyor upsell you into paying for title research you don’t need.
Either way, get a written quote before work starts, and confirm what the surveyor will and won’t document, since “no two properties are alike” and pricing swings with terrain, vegetation, and how complete the existing records are, according to Alliance Land Surveyors. If you’re weighing a survey against simply selling the parcel as-is, a buyer offering on raw acreage can sometimes move forward without either party paying for a new survey, though that depends on what the closing title company needs to clear title on your specific parcel.
The short answer
Order a boundary survey when you only need to know where your lines and corners are and no lender is dictating otherwise. Order an ALTA/NSPS Land Title Survey when a lender or title insurer wants extended title coverage, when the deal involves out-of-state parties who need a common standard, or when easements, encroachments, and access all need to be nailed down before closing. The ALTA version costs more because it does more, not because surveyors are padding the bill for the same work.
