Mortgage closing survey: mortgage survey cost, location survey, and what your lender actually requires
A mortgage survey, also called a mortgage location survey or location survey, is a lower-cost drawing that shows where the house and improvements sit relative to the property lines taken from the deed. It is prepared for the lender and title insurer, not to set your corners. It is not a boundary survey: the surveyor does not independently determine or monument the lines. A mortgage or location survey typically costs $200 to $700; a full boundary survey runs $450 to $1,000.

What a mortgage survey is, and what it is not
When a lender or title company asks for "a survey" at closing, they usually mean one of a few different products, and they cost very different amounts. The cheapest is the mortgage survey, sometimes called a mortgage location survey, mortgage inspection or simply a location survey. A licensed surveyor plots the house, garage, driveway and fences relative to the boundary lines as taken from the recorded deed, and hands the lender and title insurer a drawing that shows nothing is obviously over a line or an easement.
The key thing to understand: a mortgage survey is deliberately not a boundary survey. On a mortgage or location survey the surveyor does not independently determine the boundary and does not set or recover the corner monuments. The lines come from the paper record, not from field-verified corners. That is why it is cheaper, and why several states require it to be labeled so it cannot be mistaken for a boundary survey. Ohio, for example, codifies the mortgage location survey as a professional opinion for the lender and title insurer in which "boundary lines are not determined," and Oklahoma requires the document to be prominently marked as a mortgage inspection report. Colorado uses an Improvement Location Certificate for the same purpose, again expressly not a boundary survey.
So if your goal is to build a fence, settle a dispute or know exactly where your corners are, a mortgage survey will not do the job. For that you need a boundary survey, where the surveyor field-determines the lines and monuments the corners.
Mortgage survey vs boundary survey vs ALTA survey
The three survey products a closing might involve, cheapest to most rigorous. Match the survey to what the deal actually needs.
| Survey | What it does | Corners set? | Typical cost |
|---|---|---|---|
| Mortgage / location survey | Plots improvements against deed lines for the lender and title insurer | No | $200 - $700 |
| Boundary survey | Field-determines the lines and monuments the corners; holds up for permits, fences, disputes | Yes | $450 - $1,000 |
| ALTA/NSPS land title survey | Commercial-grade survey certified to buyer, lender, title insurer and title company | Yes | $2,000 - $10,000+ |
Full pricing by survey type is in the land survey cost guide. For commercial closings, see ALTA survey.
Do you actually need a survey to close or get a mortgage?
Often, no new survey is required. Whether you need one usually comes down to the title policy's "survey exception." If the title company has not reviewed and accepted a current survey, it lists a survey exception on the policy, which leaves boundary and encroachment matters uninsured. A survey the title company accepts lets it delete or narrow that exception, which is what lenders and investors want. That acceptable survey can be a brand-new one, or an existing survey paired with an affidavit from the seller that nothing has changed.
Texas is the clearest example. A seller can supply an existing survey plus a notarized T-47 Residential Real Property Affidavit swearing no fence, pool or addition has been built since the survey was made. If the title company accepts them, the buyer pays for no new survey. If the seller cannot produce a survey or the affidavit is rejected, a new one goes back on the closing table. Many title underwriters also waive the survey requirement entirely for one-to-four family homes in a platted subdivision up to a value cap, though that does not apply to acreage, new construction, or commercial deals.
The takeaway: ask early in the deal whether the seller has an existing survey and will sign an affidavit. If not, order a survey in parallel with the rest of closing rather than three days before, when rush fees start.
Can you reuse an existing survey at closing?
This is the decision that sets your survey line at closing, and it is decided by facts about the property, not by negotiation. Find your row, then ask the title company to confirm it in writing before you order anything.
| Your situation | What the title company usually does | What it costs you |
|---|---|---|
| Nothing has changed on the ground and the seller signs an affidavit | Usually accepted | Endorsement fee only, no new survey |
| A pool, addition, deck or new fence went in after the survey date | Usually rejected | New survey, $200 to $700 location, $450 to $900 boundary |
| The seller cannot find the old survey | Nothing to rely on | New survey, order it the week you go under contract |
| The seller misses the contract deadline to deliver survey and affidavit | Buyer typically orders one | New survey, sometimes at seller expense under the contract |
| The survey is more than about ten years old | Depends on underwriter and lender overlay | Ask early. Recertification by the original firm is $150 to $400 |
| Cash purchase with no lender involved | Title company decides alone | You may decline the coverage, but you keep the boundary risk |
| New construction, or a lot that was recently replatted | Stale by definition | New survey, plus an as-built at permit closeout |
The money sits in the second column. When an existing survey is accepted, you pay only for the endorsement that amends the survey exception on the policy. Texas prices that as a percentage rather than a flat fee: published schedules put the area and boundary amendment at 5 percent of the owner title policy premium for residential property and 15 percent for vacant land. When the existing survey is rejected, you are buying a survey, and the only question left is how fast. Full detail on the coverage side is on the survey exception in title insurance.
Does your loan require a survey to close?
This is the question behind most closing survey panic, and the answer surprises people: no major loan program mandates a boundary survey as a condition of the loan. The requirement almost always originates with the title insurer, which wants the survey exception removed from the policy, or with the lender's own closing instructions. Knowing who is actually asking tells you whether the requirement is negotiable.
| Loan or closing scenario | Required by the program itself? | Who actually asks, and why |
|---|---|---|
| Conventional purchase | No | The title company, to delete the survey exception from the owner's title policy |
| FHA purchase | No, not automatically | Lender or title company, commonly after the appraiser notes a possible encroachment |
| VA purchase | No, not automatically | Same trigger: an appraisal note, an addition near a line, or a question about access |
| USDA rural purchase | No, not automatically | Frequently asked where boundaries are unclear or the parcel was never platted |
| Refinance | No | Some lenders accept an existing survey with an owner affidavit that nothing has changed |
| Cash purchase, no lender | No | Nobody, unless you want survey coverage on your own owner policy |
| New construction | Often yes in practice | The building department, for setback verification and a foundation location survey |
| Texas residential closings | No | A T-47 affidavit commonly lets the title company rely on the existing survey instead |
What people mean by a "title survey"
"Title survey" is a loose, practical term. It means whatever survey the title company needs to be comfortable insuring your boundaries and removing the survey exception. Depending on the deal, that can be satisfied by an existing survey plus an affidavit, a fresh boundary survey, or, for larger and commercial transactions, a full ALTA/NSPS land title survey.
The ALTA/NSPS land title survey is the specific, standardized version. It is built to minimum standards jointly published by the American Land Title Association and the National Society of Professional Surveyors, updated every five years, with a new edition effective in February 2026. The surveyor certifies it to named parties, typically the buyer, the lender, the title insurer and the title company, and it shows boundaries, improvements, easements, rights of way and encroachments. Every ALTA survey serves a title purpose, but not every "title survey" needs to be a full ALTA survey. On a house, a boundary survey or an accepted existing survey usually does the job; ALTA is for commercial and higher-risk property.
How to get the survey your closing needs
1.
Ask what the title company requires
Before ordering anything, ask your title company or closing attorney exactly what they need to remove the survey exception: a new survey, or an existing survey plus an affidavit. This one question can save you several hundred dollars.
2.
Check for an existing survey
Ask the seller for any prior survey and, in states like Texas, whether they will sign an affidavit that nothing has changed. If the title company accepts it, you may not need a new survey at all.
3.
Order the right product
If a new survey is needed, order a mortgage or location survey when the title company only wants improvements located, or a boundary survey when you also need the corners set for a fence, addition or dispute. Commercial deals order an ALTA survey.
4.
Get quotes early and in parallel
Post the job and compare quotes from licensed local surveyors while the rest of closing proceeds. Ordering three days before closing is how you end up paying rush fees.
Mortgage and closing survey questions
Can I use an old survey for closing?
Often yes, if nothing on the property has changed and the seller will sign an affidavit saying so. Title companies reject an existing survey when improvements went in after its date: a pool, an addition, a deck, a relocated fence. Ask the seller in the first week of the contract, not the week of closing.
Does the lender or the title company require the survey?
Usually the title company, acting for the underwriter. Fannie Mae and Freddie Mac do not universally mandate a survey and defer to individual lender overlays, so the requirement most buyers hit comes from the title side, which needs an acceptable survey to amend the standard survey exception on the policy.
What happens if the seller does not deliver the survey on time?
The contract usually lets the buyer order a new one, and in many standard forms the seller can end up paying for it. Deadlines are short, commonly a few days after the effective date. If you are the buyer, calendar that date on day one, because a missed deadline is what turns a $0 survey line into a $700 one.
Is a mortgage survey the same as a boundary survey?
No. A mortgage or location survey plots the improvements against the deed lines and does not set the property corners or independently determine the boundary. A boundary survey field-determines the lines and monuments the corners. Do not rely on a mortgage survey for a fence, construction or a boundary dispute.
How much is a mortgage survey?
A mortgage or location survey typically costs $200 to $700, the least expensive survey type, because the surveyor works from the deed rather than field-determining and monumenting the corners. A full boundary survey runs $450 to $1,000 for a typical lot, and a commercial ALTA survey starts around $2,000.
Do I need a survey to refinance?
Sometimes. Many refinances do not require a new survey if the title company will accept an existing one. Some lenders or title companies want a recent or updated survey to confirm no new encroachments or setback problems. It varies by lender and state, so ask your title company early.
Who pays for the survey at closing, buyer or seller?
It is negotiable and varies by market and contract. The buyer commonly pays because they benefit, while sellers often provide an existing survey plus an affidavit instead. In Texas, if the seller cannot furnish an acceptable existing survey and affidavit, the contract shifts the cost of a new survey per its terms.
How long is a survey good for?
There is no legal expiration. Title companies and lenders often accept a survey that is a few years old if nothing on the property has changed. Any new fence, addition or subdivision can make it obsolete, which is when an affidavit like the Texas T-47 is used to attest it is still accurate, or a new survey is ordered.
What is a location survey?
A location survey is another name for the mortgage survey: it locates the improvements relative to the deed boundary lines for the lender and title insurer. It does not set corners or independently determine the boundary. In Colorado the same purpose is served by an Improvement Location Certificate, which is likewise not a boundary survey.
