Your lender says they need a mortgage survey before closing. You’re buying a townhome. It shares two walls, sits on a lot the size of a parking space, and the HOA controls half of what you can see out the window. So what exactly is the surveyor drawing?

That question comes up on nearly every townhome deal. The answer matters, because a mortgage survey covers less than most buyers assume.

What a Mortgage Survey Actually Is

A mortgage survey is field work ordered to satisfy a lender before a loan funds. The surveyor locates the unit, the lot lines and the visible improvements, then puts them on a drawing. The lender wants proof the building sits where the paperwork says it does.

The name varies by state, and that trips people up. Some places call it a location survey. Others call it a mortgage inspection, which in certain states is not a boundary survey at all and carries much weaker protection. Ask your lender and your surveyor what product you’re actually getting, in writing, before you pay for it.

Scope is the part buyers misread. A mortgage survey answers the lender’s question, and the lender’s question is narrow. It is not a full investigation of your rights, your HOA rules or your future plans.

Townhomes Break the Standard Lot Picture

A detached house sits in the middle of a lot with air on all four sides. A townhome does not. That single difference changes what the drawing shows and what it can’t show.

Your lot may be smaller than your home feels

Many townhomes sit on a fee simple lot that stops at the exterior walls, or close to it. Everything else, meaning the drives, the greenbelt, the visitor parking, belongs to the association. Your survey shows a narrow rectangle, and buyers are often shocked by how small it looks on paper.

Other townhome projects are set up as condominiums instead. In that case you may own an air space unit and no dirt at all. The ownership structure decides what a surveyor can even draw, so read your declaration before you assume.

Party walls live on the line

The wall between you and your neighbor usually sits on or near the shared lot line. The survey shows where that line runs, but it doesn’t tell you who maintains the wall or who pays when it fails. That answer lives in the party wall agreement or the declaration, not on the drawing.

The association owns more than you think

Roofs, exterior siding, driveways and fences are frequently association property or limited common elements. A surveyor can show you a fence and its location. Whether you’re allowed to move it is a governing document question.

The Questions That Come Up Every Time

Same list, deal after deal. Here’s what buyers actually ask and what the survey can honestly tell them.

Does my patio or enclosure belong to me? The survey shows whether the structure sits inside your lot lines. It does not confirm the HOA approved it or that a permit was pulled, and unapproved enclosures are extremely common in townhome projects.

Why does my fence not match my lot line? Because fences get built for convenience, not accuracy. The survey shows the gap. Fixing it is a conversation with the association and possibly the neighbor.

Do I own the roof over my unit? Usually not in a townhome setup. A surveyor cannot answer this at all, since roof ownership is a legal question answered by the declaration.

Can I add on later? The survey shows setbacks if you order that item. It does not tell you what the HOA architectural committee will allow, and that group often says no long before the city does.

Is my parking space on the survey? Only if it’s part of your lot. Assigned spaces in common area are typically shown on the plat or the declaration exhibits instead.

What a Mortgage Survey Will Not Do for You

This is where townhome buyers get hurt. The survey protects the lender first and you second, and there’s a real gap between those two jobs.

It won’t interpret your HOA documents. It won’t confirm permits. It won’t tell you whether the previous owner’s improvements were legal. And in states where the product is a mortgage inspection rather than a boundary survey, it may carry no reliance for you whatsoever.

Certification matters here too. Read the block on the drawing and see whose name appears. If only the lender and title company are listed, you’re looking at somebody else’s protection.

What to Do With the Drawing Once You Get It

Read it during your inspection window, not the night before closing. That timing is the difference between negotiating and signing.

Do four things with it:

• Compare the improvements shown to what you walked through
• Flag any structure that crosses a line or sits in common area
• Match the lot lines against the recorded plat
• Take anything odd to your title company before closing

Then ask the association for the architectural approval file on your specific unit. Compare that file to the survey. Mismatches between the two are the single most common townhome problem, and they become your problem the moment you take title.

When You Should Order Something Better

A mortgage survey is fine for a clean unit in a well-run project where you plan to change nothing. That describes a lot of buyers. It doesn’t describe all of them.

Order a full boundary survey, or add scope, if the unit has an enclosure or added structure, if a fence looks wrong, if you plan to build anything, or if the project has a history of disputes. Paying a bit more during diligence beats inheriting a violation.

Cash buyers should pay attention here. No lender is ordering anything for you, so nobody is checking unless you do it yourself.

Frequently Asked Questions

Who orders the mortgage survey on a townhome purchase?

The lender requires it, but the buyer usually pays and the closing agent often places the order. That arrangement means the product gets picked to satisfy the lender rather than to answer your questions. Ask early whether you can add scope for a modest fee. Doing it during the original field visit costs far less than a second trip.

Is a mortgage survey the same as a boundary survey?

Not always, and the difference is worth understanding. In some states a mortgage survey is a full boundary survey performed to lender requirements. In others, a mortgage inspection is a lighter product with limited liability and no property corners set. Ask your surveyor which one you’re buying and what it does and does not certify.

Do townhomes even need a survey if the HOA owns everything?

It depends on how the project is structured, and that varies widely. Fee simple townhome lots usually get surveyed like any other lot. True condominium units often rely on the recorded condominium plat instead, so the lender may waive field work. Your title company can tell you which category your unit falls into.

How much does a mortgage survey cost for a townhome?

Fees vary by market, parcel complexity and how much record research the job requires, so a firm number here would be a guess. Townhome work is often cheaper than a detached lot because the parcel is small and the boundary is short. Additional scope like setbacks or improvement detail adds cost.

What if the survey shows an encroachment?

Take it to your title company and your agent right away, since timing decides your options. Some encroachments get resolved with an agreement, an endorsement or a seller fix before closing. Others are minor enough that everyone accepts them and moves on. Closing first and discovering it later removes all of your leverage.
