When you hear the phrase mortgage survey vs. boundary survey, it is easy to assume they mean the same thing. Both involve a licensed surveyor. Both produce a drawing of your property. But they serve different legal purposes, and mixing them up can cause real problems at the bank or in court.
What Is a Mortgage Survey?
A mortgage survey shows the approximate location of structures on a lot. Lenders require it at closing to confirm that buildings sit within the property lines. It does not set legal boundary lines and cannot resolve disputes or be used in court.
A mortgage survey is mainly a tool for lenders. It answers one simple question: Are the buildings on the lot where they should be? If the answer is yes, the lender moves forward. If a structure crosses a line, the loan may pause until the issue is resolved.
What a Mortgage Survey Includes
- Approximate lot line positions based on existing deeds and plats
- Location of the house and other structures on the lot
- Visible easements already recorded in county records
- Basic features such as driveways and concrete slabs
What a Mortgage Survey Does Not Include
- Physical corner pins or iron markers placed in the ground
- A legal determination of where boundary lines fall
- Research into title disputes or conflicting deed descriptions
- Court-admissible boundary documentation
What Is a Boundary Survey?
A boundary survey legally establishes the exact edges of a property. A licensed surveyor researches deeds, measures the land, and sets physical corner markers. The certified plat is admissible in court and required for land splits or subdivision filings.
A boundary survey goes much deeper than a mortgage survey. The surveyor studies old deeds, checks county records, and measures the land with GPS and total station equipment. Then they place iron pins at every corner of your property. This type of survey is needed when the location of a property line carries real legal or financial weight.
What a Boundary Survey Includes
- Full research of recorded deeds, plats, and easements
- Precise field measurements using GPS and total station equipment
- Iron pins or concrete monuments set at every corner
- A certified plat stamped and signed by a licensed PLS
- Any encroachments or overlaps identified and noted on the plat

Which One Do You Actually Need?
If your lender requires a survey at closing, a mortgage survey is usually enough. If you need legal proof of where your property ends, such as for a title dispute, a land split, or a permit application, only a boundary survey qualifies. The two are not interchangeable in Mississippi courts or county offices.
The simplest way to decide is to ask one question: Does the result need to hold up legally? If not, a mortgage survey works. If yes, you need a boundary survey.
Get a Mortgage Survey When…
- Your lender or title company requires it at closing
- You are refinancing and need a current property drawing
- There are no known disputes and the title is clean
- You need a quick check that no obvious encroachment exists
Get a Boundary Survey When…
- A title exception must be cleared because an encroachment was flagged
- You are splitting or re-platting land
- Your deed has an old legal description with missing landmarks
- A neighbor placed an improvement that appears to cross onto your lot
- You are applying for a permit that requires a certified plat
What Mississippi Law Requires
Under Mississippi Code Section 73-17, any survey that locates or retraces a property boundary must be performed by a licensed Professional Land Surveyor. Only a PLS can certify a legal boundary determination in Mississippi. Surveys done by anyone without a valid PLS license cannot be recorded with the Lee County Chancery Court.
A mortgage survey may or may not involve a licensed PLS depending on what the lender requires. A boundary survey always requires one by law. Always ask to see a surveyor’s active license number before hiring them for any boundary work.
Properties in older sections of Tupelo where plat records are aging may need extra title research before a boundary survey can be completed. Ask your surveyor about this upfront so there are no delays.
Frequently Asked Questions
What is the difference between a mortgage survey and a boundary survey?
A mortgage survey shows where structures sit on a lot and satisfies a lender at closing. A boundary survey is a certified legal document that establishes exact property lines. Only the boundary survey holds legal standing and is admissible in Mississippi courts.
Do I need a boundary survey to buy a house?
Most lenders only require a mortgage survey to close. A boundary survey is not required unless your title commitment flags an encroachment or a survey exception that must be cleared before closing.
Can a mortgage survey be used instead of a boundary survey?
No. A mortgage survey has no legal standing for boundary disputes, permits, or land split applications. Only a certified boundary survey prepared by a licensed PLS qualifies for those purposes.
Who can perform a boundary survey in Mississippi?
Under Mississippi Code Section 73-17, only a licensed Professional Land Surveyor registered with the Mississippi Board of Licensure for Professional Engineers and Surveyors can certify a boundary survey in the state.
