Nobody signs a purchase agreement expecting to rewrite it. But once an ALTA survey lands on the table, that’s often exactly what happens.
A purchase agreement gets written before anyone has walked the property with instruments. It relies on the deed description, the seller’s word, maybe an old plat pulled from a file drawer. The ALTA survey is where those assumptions meet the ground. When the two don’t match, deal terms can shift right along with them. Not just the closing date. The price, the exhibits, sometimes the whole scope of what’s being bought.
Here’s what buyers and sellers should watch for once that survey shows up mid-contract.
1. The Survey Objection Period: A Contract Clock Most Buyers Don’t Track Closely
Most commercial purchase agreements include a set number of days for the buyer to review the survey and raise objections in writing. This window is short. Ten to fifteen business days is common, though every contract is different.
Miss that window, and the buyer may lose the right to object later. It doesn’t matter what the survey shows. If the deadline passes without a written objection, the buyer often has to accept the property as surveyed.
This is why the survey should never sit unread in an inbox. As soon as it arrives, someone on the buyer’s side, usually the attorney or a project manager, needs to read it line by line. Flag anything unclear. Send questions to the surveyor early. Waiting even a few days can eat into the response window and leave no time to negotiate.
2. How a Discrepancy Between Legal Description and Survey Can Reopen Price Negotiations
Sometimes the survey shows less usable land than the buyer expected. Maybe a floodplain eats into the buildable area. Maybe a utility easement runs through the middle of what was supposed to be parking. Maybe the total acreage is smaller than the deed implied.
When that happens, the numbers change. A buyer who priced the deal per square foot or per acre now has real grounds to ask for a lower price. This isn’t usually a reason to walk away from the deal. It’s a reason to sit back down at the table.
Sellers should expect this conversation if their property has never been surveyed to ALTA standards before. Old deed descriptions, especially ones written decades ago, are often less precise than what a current survey reveals.
3. Survey-Triggered Contingencies: When Findings Give Either Party an Exit Clause
Many commercial contracts include a survey contingency. This works differently from a financing or inspection contingency. It’s tied specifically to what the surveyor finds on the ground, not the condition of a building or a buyer’s loan approval.
Things that commonly trigger this clause include an encroachment from a neighboring building, a structure that sits too close to a setback line, or an access point that doesn’t legally exist the way everyone assumed. If a finding like this shows up and it’s serious enough, either party may have the right to walk away.
More often, though, this clause becomes leverage. The buyer uses the finding to ask for a fix, a credit, or new terms. The seller decides whether solving the problem is worth keeping the deal alive.
4. Escrow Holdbacks and Indemnification Clauses Born From Survey Findings
Not every survey issue needs to stop. A lot of deals move forward with the problem still unresolved, just handled differently.
One common approach is an escrow holdback. A portion of the sale proceeds sits in a separate account until the issue is fixed. Say a shed from the neighboring lot sits three feet over the property line. The parties can close the sale and hold back enough money to cover removing that shed later.
Another option is an indemnification clause. Here, the seller agrees in writing to take responsibility if the issue causes a loss down the road. Title insurers sometimes get involved too, adding a specific endorsement that covers a known survey issue instead of excluding it from coverage entirely.
These tools let a deal close on schedule while giving the buyer real protection against a problem that isn’t fully solved yet.
5. Amending the Purchase Agreement: What Changes When New Boundary or Easement Data Surfaces
When survey findings are significant enough, the purchase agreement itself often needs an amendment. This isn’t the same as starting over.
An amendment usually touches a few specific parts of the contract. The legal description might get corrected to match the surveyed boundary. Exhibits or attachments might be replaced with updated maps. The purchase price might be adjusted based on the acreage difference. Closing conditions might be added, like requiring proof that an encroachment was removed before funds are released.
Attorneys typically handle this by redlining the original agreement rather than drafting a brand new one. It keeps the paper trail clean and shows exactly what changed and why. For anyone involved, that trail matters if a dispute comes up later.
The Real Lesson Here
A survey doesn’t cause problems. It uncovers ones that were already there, hiding behind an old deed or a handshake assumption nobody double checked.
The deals that survive a scope change aren’t the ones without surprises. They’re the ones where someone actually read the survey on time, understood what it meant, and knew which lever in the contract to pull. That’s not luck. That’s just paying attention at the right moment.
