Do you need a new survey to buy a home in Flower Mound?
Not always. In most Texas resale purchases, the title company can reuse the seller's existing survey if the seller signs a T-47 Residential Real Property Affidavit swearing nothing has changed on the property. That reuse typically saves you $500 to $700, since a new residential boundary survey runs about $400 to $700. You need a brand-new survey when no existing survey is available, when the property has changed since the last one (a pool, addition, fence, or new structure), or when the seller will not sign the T-47.

Somewhere between your accepted offer and closing, the word "survey" is going to come up, and for a lot of Flower Mound buyers it is the first line item they do not fully understand. It is also one where a few hundred dollars and a signature can go either way depending on how the contract is written and how fast everyone moves.
Here is how surveys actually work in a Texas purchase, and how to avoid overpaying or, worse, getting stuck with a title issue at closing.
What the survey and the T-47 actually do
A property survey is a drawing that shows the boundaries of the lot, where the home and other structures sit on it, easements, encroachments, and where the fence lines fall relative to the actual property line. Your title company needs an acceptable survey to issue title insurance without a boundary exception.
Here is the key point most buyers miss: the survey does not always have to be new.
Texas gives the title company two paths. It can require a brand-new survey, or it can accept the seller's existing survey paired with a signed, notarized T-47 Residential Real Property Affidavit. The T-47 is the seller swearing, under oath, that the existing survey is still accurate and describing any changes made since it was done. That affidavit is what lets the title company rely on an older survey.
Reusing the existing survey with a T-47 is the cheaper path, and it has become the more common choice in Texas resale transactions.
The money side
The savings are real and specific.
- A new residential boundary survey in the Flower Mound area typically runs $400 to $700 for a standard single-family lot.
- Reusing the existing survey with a T-47 generally saves the buyer or seller $500 to $700 on a residential deal, and much more on an acreage property.
So the difference between "new survey" and "existing survey plus T-47" is usually a few hundred dollars. Not huge, but not nothing, and on a tight closing it is worth getting right rather than defaulting to a new order out of habit.
Who pays for it
In a standard Texas transaction, the buyer typically pays for the survey. The promulgated TREC contract assigns the survey cost, and it is handled in Paragraph 6 of the contract. Who pays for a new survey is negotiable between buyer and seller, but the default in most Flower Mound offers puts it on the buyer, and it is rarely negotiated away at the offer stage.
There is a timing wrinkle worth knowing. The contract gives a set number of days, usually three to five after the effective date, to deliver the existing survey and the signed T-47. Miss that deadline and the responsibility can flip, meaning the seller may end up owing a new survey instead. That is a small detail with real dollars attached, which is exactly why the contract's survey paragraph deserves attention rather than a quick skim.
When you actually need a new survey
Sometimes the existing-survey-plus-T-47 route simply is not available, and a new survey is the right call. The most common reasons:
- There is no existing survey. Nothing to reuse, so a new one gets ordered.
- The property changed since the last survey. A new pool, room addition, deck, outbuilding, driveway, or moved fence line can all make an old survey inaccurate. The T-47 asks the seller to disclose exactly these changes.
- The seller will not sign the T-47. Without that affidavit, the title company has no basis to rely on the old survey.
- The lender or title company requires a current one. Some lenders or title underwriters insist on a new survey regardless, especially on certain loan types or when the old survey is very dated.
- New construction. On a brand-new Flower Mound build in a community like Furst Ranch, Whyburn, or Lakeside, there is no prior survey of a finished home, so a new one is standard.
If any of these apply, paying for a new survey is not a mistake. It is buying certainty about exactly what you own, which on a move-up home is worth far more than the survey fee.
Why this matters more than it looks
A survey is easy to treat as a formality, but it is often the document that catches real problems: a fence built two feet over the line, a neighbor's shed encroaching, an easement running through the exact spot you wanted a pool. Finding that out before closing is a gift. Finding it out after is a headache you paid to avoid and did not.
This is one of those small contract details I make sure every buyer understands before we get to the closing table, because a clean survey and a correctly handled Paragraph 6 keep the title clean and the closing on schedule.
Frequently Asked Questions
What is a T-47 in Texas?
The T-47 is a Residential Real Property Affidavit, a notarized document the seller signs swearing that an existing survey is still accurate and disclosing any changes made to the property since it was done. It allows the title company to rely on the older survey instead of requiring a new one.
How much does a new survey cost in the Flower Mound area?
A standard residential boundary survey typically runs about $400 to $700 for a single-family lot. Acreage and larger or irregular properties cost more. Reusing an existing survey with a T-47 usually saves $500 to $700 on a residential deal.
Who pays for the survey when buying a home in Texas?
In most Texas transactions the buyer pays for the survey, and it is addressed in Paragraph 6 of the TREC contract. It is negotiable between buyer and seller, but the buyer paying is the common default and is rarely changed at the offer stage.
Do I need a new survey if the seller has an old one?
Often no. If the seller signs a T-47 confirming the existing survey is still accurate and nothing significant has changed, the title company can usually reuse it. You need a new survey if the property has changed, no survey exists, the seller will not sign the T-47, or the lender or title company requires a current one.
What happens if the survey and T-47 are not delivered on time?
The contract sets a deadline, usually three to five days after the effective date, to deliver the existing survey and signed T-47. If that deadline is missed, responsibility for obtaining a new survey can shift to the seller. Watching that date matters.
Bringing it together
For most Flower Mound resale purchases, you will not need a brand-new survey as long as the seller has one and signs the T-47, and that can save you several hundred dollars. When the property has changed or no survey exists, a new one is worth every penny for the certainty it buys. Either way, the survey paragraph in your contract is not a place to autopilot.
