How to Read a Property Survey (And Why It Matters)

When you're buying vacant land, there's one document that tells you more about a property than almost anything else — the property survey. Yet for many first-time buyers, it's also one of the most confusing.
If you've ever stared at a survey and thought, "What am I even looking at?" — you're not alone. At KPA Land, we want every buyer to feel confident and informed before they sign anything. So let's break down exactly what a property survey is, how to read one, and why it should be one of the first things you review when considering a land purchase.
What Is a Property Survey?
A property survey is an official document prepared by a licensed land surveyor that defines the exact boundaries of a piece of land. Think of it as the legal "fingerprint" of your property — it tells you precisely where your land begins and ends, what's on it, and how it relates to neighboring parcels and roads.
Surveys are used for:
Confirming boundary lines so there are no disputes with neighbors
Verifying lot size — making sure you're getting the acreage you're paying for
Identifying easements — areas where someone else may have the legal right to cross or use part of your land
Supporting title insurance and financing
Planning any future construction or improvements
Types of Property Surveys
Not all surveys are the same. Here are the most common types you'll encounter when buying vacant land:
Boundary Survey The most common type for vacant land. It establishes the exact corners and edges of your property using legal descriptions and physical markers.
Topographic Survey Shows the physical features of the land — elevation changes, slopes, waterways, and natural landmarks. Especially useful if you're planning to build.
ALTA/NSPS Survey A more detailed and standardized survey often required for commercial transactions or by lenders. It includes everything a boundary survey does, plus easements, encroachments, and other title-related details.
Subdivision Plat If your parcel is part of a larger subdivision, it may reference a recorded plat map — a master survey of the entire development showing all lots, roads, and common areas.
For most rural vacant land purchases, you'll be working with a boundary survey or a subdivision plat.
How to Read a Property Survey
At first glance, a survey can look like a maze of lines, numbers, and abbreviations. Here's how to make sense of it:
1. Find the Title Block
In one corner of the survey (usually the bottom right), you'll find a title block. This contains:
The property owner's name
The legal description of the land
The surveyor's name, license number, and signature
The date the survey was completed
Always check the date — an old survey may not reflect recent changes to the land or neighboring properties.
2. Locate the North Arrow and Scale
Every survey has a north arrow showing which direction is north, and a scale bar showing the ratio of the drawing to real-world measurements. This helps you understand the orientation of the property and estimate distances on the map.
3. Read the Boundary Lines
The bold outer lines of the survey represent your property boundaries. Along each line, you'll see:
Bearings — directions expressed in degrees, like "N 45° 30' E" (North, 45 degrees, 30 minutes East). This tells you the angle of each boundary line.
Distances — the length of each boundary line, usually in feet.
Together, these measurements define the exact shape and size of your parcel.
4. Look for Monuments and Markers
Survey corners are marked with physical monuments — often iron pins, rebar, or concrete markers driven into the ground. On the survey, these are typically shown as small squares or circles at the corners of the property. You may see notations like "IRF" (Iron Rod Found) or "IRS" (Iron Rod Set).
5. Identify Easements
Easements are areas within your property where another party has legal rights — for example, a utility company's right to run power lines across your land, or a neighbor's right to use a shared road. Easements are usually shown as dashed lines with a label describing their purpose and width.
Pay close attention to easements. They don't take away your ownership, but they can affect what you're able to build or do in those areas.
6. Check for Encroachments
An encroachment happens when something — a fence, a building, a driveway — crosses over a property boundary. Surveys will often note if a neighboring structure is encroaching on your land, or if something on your land crosses onto a neighbor's property. These can become legal issues, so it's important to know about them upfront.
7. Read the Legal Description
Every survey includes a written legal description of the property — a formal text version of where the land is located. You'll often see two types:
Metes and Bounds — describes the boundary by starting at a point and following specific directions and distances all the way around the perimeter
Lot and Block — references a recorded plat map with a simple lot number and subdivision name
The legal description on the survey should match the legal description in the deed. If they don't match, that's a red flag worth investigating.
Why a Property Survey Matters When Buying Land
Here's the bottom line: without a survey, you're essentially buying land on faith.
You might think you're purchasing 5 acres when the actual boundary gives you 4.2. You might build a fence right where a utility easement runs. You might discover a neighbor's shed has been sitting on your corner for the past decade.
A survey protects you from all of that. It gives you:
Peace of mind — you know exactly what you own
Legal protection — boundary disputes are much easier to resolve with a survey on record
Planning clarity — you can make informed decisions about building, fencing, or improving the land
Better negotiating power — if the survey reveals issues, you can negotiate the price or ask the seller to resolve them before closing
What to Do If There's No Existing Survey
Some rural parcels — especially older ones — may not have a recent survey on file. In that case, you have a few options:
Ask the seller if they have any prior survey records
Contact the county — many counties have recorded plat maps available online or at the recorder's office
Order a new survey — a licensed land surveyor can conduct a boundary survey for you, typically ranging from a few hundred to a couple thousand dollars depending on the size and complexity of the parcel
Use owner financing to your advantage — with KPA Land's owner financing, you have flexibility to get a survey done before or shortly after purchase without the pressure of a bank timeline
Final Thoughts
A property survey might not be the most glamorous part of buying land — but it's one of the most important. Taking the time to understand what you're looking at gives you confidence, clarity, and protection as a buyer.
