A vacant land transaction coordinator runs a file whose critical path sits outside the contract. On a house, nearly every deadline belongs to somebody who signed something. On land, three of the deadlines that decide whether the deal closes belong to a county health department, a county appraisal district, and a stack of records filed decades before anyone in your file was born. None of the three read your contract. All three can be checked on the day the file opens.
This is the part of land work that surprises coordinators who are otherwise very good at their jobs. The residential template assumes the transaction owns its own calendar. Land removes that assumption quietly, and the removal does not announce itself.
Nothing turns red. The feasibility period simply runs out against a test that could not have been scheduled, or a tax bill arrives eight months after funding, addressed to a buyer who has never heard the words rollback tax.

The calendars a house file never has to ask about
Our guide to property type requirements covers what substitutes for what when a file is not a resale house: which contract form governs, what the inspection examines, whether the deed conveys the whole asset. Land breaks those assumptions harder than any other property type, and it breaks one more that the substitution test does not reach.
Call it the outside calendar problem. A residential resale file has one calendar, negotiated in the contract and enforced by people who are parties to it. A land file has that calendar plus three others. Each of the three belongs to an entity with no obligation to your closing date, no awareness that a closing date exists, and in two cases, no way to be hurried.
Every vacant land transaction coordinator eventually learns these three the expensive way. Learning them at intake is cheaper.
Calendar one: the health department decides when your feasibility period is real
If a parcel has no sewer, the buyer needs an on-site system, and sizing one requires a percolation or soil evaluation test. Where the water table is high, that test is only meaningful when groundwater sits at its seasonal peak, because a system designed against August soil may fail in March.
So health departments run testing seasons. Anne Arundel County, Maryland is a useful example because it publishes its dates. Its Environmental Health Bureau performs wet season evaluations in the months when groundwater is highest. On April 15, 2026 the department announced it had stopped scheduling percolation tests for the season, because monitoring wells showed water levels receding.
Appointments already on the calendar would still be honored, but against declining groundwater. New appointments were finished for the year.
Read that as a coordinator rather than as a property owner. A contract signed in late April with a 45-day feasibility period contains a contingency the buyer cannot satisfy. Not a slow one. An impossible one. The next chance at a valid wet season result is roughly nine months out, and no amount of follow-up moves it, because the constraint is groundwater rather than staffing.
The intake question is one line. Does this parcel have public sewer, and if not, has a valid perc or soil evaluation already been performed, with the report in hand? If the answer is no and the calendar sits outside the local testing window, the feasibility period in the draft contract is decorative, and somebody needs to know before signatures rather than after.
Calendar two: the appraisal district bills your buyer after closing
Agricultural, timber, and open space appraisal programs tax land on what it produces rather than what it would sell for. The gap is enormous, which is the point of the program. It is also a liability that sits dormant in the file until the buyer does the ordinary thing a buyer does with land, which is change what it is used for.
Texas states the mechanism plainly. Under Texas Tax Code section 23.55, when the use of land appraised under the agricultural subchapter changes, an additional tax is imposed. It equals the difference between the taxes imposed and the taxes that would have applied at market value, for each of the three years preceding the year of the change.
A tax lien attaches to the land on the date the change of use occurs. The chief appraiser, not the parties, decides that a change happened. The lookback dropped from five years to three effective June 15, 2021, and the automatic seven percent interest came out, so interest now applies only if the additional tax goes delinquent.
Run the numbers on a real parcel. Take 15 acres carrying an agricultural productivity value of $800 per acre against a market value of $25,000 per acre, in a jurisdiction with a combined rate of 2.2 percent.
| Line | Figure |
|---|---|
| Annual tax at agricultural value ($12,000 x 2.2%) | $264 |
| Annual tax at market value ($375,000 x 2.2%) | $8,250 |
| Annual difference | $7,986 |
| Three-year additional tax at change of use | $23,958 |
Roughly twenty-four thousand dollars, secured by a lien, triggered by the buyer breaking ground. And the contract has usually already decided who pays it.
The Texas Real Estate Commission’s Unimproved Property Contract, TREC form 9-18, handles this in its prorations paragraph. If the sale or the buyer’s use of the property after closing results in the assessment of additional taxes, penalties or interest for periods prior to closing, those assessments are the obligation of the buyer.
That allocation is defensible. It is also invisible to a buyer who has read the price and the closing date and skimmed the rest. A vacant land transaction coordinator who flags the exemption status at intake, records the rollback allocation in the file summary, and puts the number in front of the agent before the option period expires has done something a residential checklist would never have prompted.
Calendar three: the records were severed long before your file existed
The third calendar is the strangest, because it already closed. Across much of the country, and heavily in Texas, Oklahoma, Colorado, Pennsylvania and West Virginia, the mineral estate has been severed from the surface estate by a deed reservation somewhere back in the chain. The seller may own every square foot of dirt and none of what sits beneath it.
This matters in the file, not just in a law review. The Texas Real Estate Research Center at Texas A&M explains that the mineral estate is dominant over the surface for exploration and production. A mineral lessee has an implied right to use as much of the surface as is reasonably necessary, without asking permission first.
The accommodation doctrine, established in Getty Oil v. Jones in 1970, gives the surface owner some relief. It is narrower than most buyers assume. In Merriman v. XTO Energy in 2013, the Texas Supreme Court held that the surface owner carries the burden of proving no reasonable alternative exists for their own existing use.
Where this surfaces in the file is Schedule B of the title commitment, as an exception, alongside any recorded oil and gas lease. Standard owner’s policies exclude coverage on minerals, so the commitment discloses the problem rather than insuring against it. Deed language is the other tell. Phrases such as “reserving all oil, gas and other minerals” or “less and except all minerals” mean a prior owner kept them.
The coordinator’s job is not to resolve severance. It is to get the commitment ordered early enough that Schedule B is read during the diligence window rather than three days before funding, and to raise the question in writing when the buyer’s stated plan is a house with a well and a barn.
The three calendars side by side
| Calendar | Who controls it | When it opens | What missing it costs |
|---|---|---|---|
| Septic feasibility | County health department | Seasonal, often winter into spring where the water table is high | The feasibility contingency cannot be satisfied, which usually means a months-long delay or a terminated contract |
| Rollback assessment | County appraisal district | Triggered by change of use, determined after the fact | Several years of back tax secured by a lien, in many states allocated to the buyer by contract |
| Mineral severance | The county records, already closed | Visible when the title commitment is issued | Surface access rights the buyer did not price and cannot undo |
Six questions that route a land file at intake
None of this needs a separate checklist per property type, which is a maintenance trap. It needs six questions asked once, on the day the file opens, before the calendar starts consuming itself.
- Is the correct form in use? Most states promulgate a distinct land contract, and routing a parcel to the residential resale form produces the wrong paper before anyone reaches a checklist.
- Public sewer, or on-site system? If on-site, is a valid perc or soil evaluation already in hand, and does the local testing season overlap the feasibility period as drafted?
- What is the current tax appraisal status: agricultural, timber, open space, or market? If it carries a productivity exemption, what does the rollback exposure calculate to, and who does the contract say pays?
- Has the title commitment been ordered, and does Schedule B disclose a mineral reservation or a recorded lease?
- Is there legal recorded access from a public road, and is it an easement of record rather than a driveway everyone has always used?
- What financing is contemplated? Raw land does not clear a conventional residential product, and a financing contingency copied from a resale template may reference a loan that will not exist for this parcel.
Four of the six are answerable from documents rather than opinions. That is what makes them a routing test instead of a judgment call. A vacant land transaction coordinator can run all six in the time it takes to set the file up, and the ones that come back wrong earn an immediate conversation.
Where this breaks in the file
The failure is rarely ignorance. Coordinators who work land know about perc seasons and rollback taxes. The failure is that these three items live in three different systems, none of which is the transaction management system: a health department portal, an appraisal district record, and a title commitment PDF that arrives by email.
Nothing connects them to the deadline that depends on them. So the septic question gets answered correctly in a note that no task is watching, and the deadline that needed the answer comes due anyway.
That is a coordination problem rather than a knowledge problem, and it is the same one that shows up in our breakdown of the 41-step transaction timeline and in the master closing checklist. ReBillion is built as an AI control plane that orchestrates your stack, so a fact established once, such as a parcel carrying an agricultural exemption, reaches every downstream step that depends on it instead of sitting in a note.
Practice varies a great deal by state. Coordinators working Texas land should read our Texas transaction coordinator guide alongside this one, and our manufactured home title conversion checklist when land and a dwelling arrive in the same file. Our pricing page shows how the coordination layer is priced.
Frequently asked questions
What does a vacant land transaction coordinator do differently from a residential file?
The core administrative work is the same, but three deadlines move outside the contract. Septic feasibility runs on the health department’s seasonal testing calendar, rollback tax exposure is determined by the county appraisal district after closing, and mineral severance is fixed in records already filed. A vacant land transaction coordinator checks all three at intake rather than at the deadline.
When can a percolation test be scheduled?
Where the water table is high, only during a defined wet season, because a system sized against dry soil may fail when groundwater peaks. Anne Arundel County, Maryland concluded its 2026 wet season scheduling on April 15, 2026. Testing windows commonly run winter into spring, so confirm the local window before agreeing to a feasibility period.
Who pays rollback taxes when land loses its agricultural appraisal?
It depends on the contract, and many promulgated land contracts assign it to the buyer. The TREC Unimproved Property Contract provides that additional assessments resulting from the sale or the buyer’s post-closing use are the buyer’s obligation. Confirm the allocation in the governing form rather than assuming, since it varies by state and by contract.
How far back do rollback taxes reach?
It varies by state. Texas Tax Code section 23.55 imposes the additional tax for the three years preceding the year the change of use occurs, reduced from five years effective June 15, 2021, with a lien attaching on the date of the change. Other states use different lookback periods, so verify against the local statute.
How do I find out whether the mineral rights were severed?
Start with Schedule B of the title commitment, where mineral reservations and recorded oil and gas leases appear as exceptions, and read the deed for reservation language such as “less and except all minerals.” A definitive answer requires a mineral title opinion from an attorney, which is worth raising with the buyer when the parcel sits in an active production region.
Does title insurance cover mineral rights on vacant land?
Standard owner’s policies generally exclude coverage on minerals. The commitment discloses what is severed rather than insuring the buyer’s ownership of it, which is why Schedule B needs to be read inside the diligence window rather than treated as closing paperwork.
