Selling a McKinney Home on Acreage: Septic, Well and Ag Exemption Issues
McKinney's eastern and southeastern edges still have properties on genuine acreage — a house on two, five or twenty acres, often with a septic system, sometimes with a well, and frequently with an agricultural valuation on part of the land.
Selling one of these is not the same as selling a suburban house. Three things routinely complicate the transaction.
1. The Septic System
On-site sewage facilities in Texas are regulated at the county level under state rules. When a property transfers, the system's condition and permitting become a live issue.
Buyers using financing will generally require a septic inspection. If the system is undersized for the house, unpermitted, or failing, that becomes a condition to be resolved before closing. Replacement of a conventional system runs from roughly $8,000, and an aerobic system on difficult soil can run considerably more. Texas Commission on Environmental Quality guidance on on-site sewage facilities sets out the regulatory framework.
2. The Well
Properties on well water need the well tested for both flow rate and water quality. A well producing insufficient flow, or water failing bacterial testing, complicates a financed sale. Some lenders have specific requirements for well-served properties.
There is also the question of whether the well is properly registered and whether any abandoned wells on the property have been plugged to standard. An unplugged abandoned well is a liability that surfaces during due diligence.
3. Agricultural Valuation and Rollback Tax
This is the one that catches sellers hardest. If part of your McKinney acreage carries an agricultural or wildlife management valuation, the property is being taxed on its productivity value rather than its market value — often a very large saving.
When that land use changes, Texas law provides for a rollback tax recovering the difference between what was paid and what would have been paid at market value, for a set number of prior years, plus interest. The Texas Comptroller's property tax assistance division publishes the current rules on agricultural appraisal and change-of-use tax.
A rollback tax liability on a McKinney acreage property can run into tens of thousands of dollars. Who pays it — and whether the sale itself triggers it — depends on the transaction and the buyer's intended use. Get this answered by your attorney or the Collin Central Appraisal District before you sign anything, not after. |
Why the Buyer Pool Is Smaller
Acreage buyers are a narrower segment to begin with. Add septic and well due diligence, potential rollback exposure, and lender caution around rural properties, and the pool narrows further. Some conventional lenders limit acreage or apply additional requirements on properties above a certain lot size.
This is why McKinney acreage properties often take considerably longer to sell than suburban homes at similar price points.
How a Cash Sale Changes It
A cash buyer has no lender imposing septic, well or acreage conditions. We assess the property including the systems and the tax position, factor it into the offer, and close without the financing obstacles that stall these transactions.

Frequently Asked Questions
Do I have to disclose a failing septic system?
Yes. A septic system's condition is a material condition of the property and must be disclosed on the Texas Seller's Disclosure Notice if you are aware of problems. Non-disclosure of a known failing system creates significant legal exposure.
Who pays the agricultural rollback tax when land changes use?
It depends on the contract terms and the circumstances of the change in use. This is genuinely complex and varies by situation. Speak to a real estate attorney and the Collin Central Appraisal District before agreeing contract terms on an ag-valued property.
Will a cash buyer still want a septic inspection?
We assess the system as part of our due diligence before making an offer, but we do not make the sale conditional on the outcome the way a lender does. What we find is reflected in the offer price rather than becoming a repair condition you must fund.
Can I sell McKinney acreage with an unregistered well?
Yes, though it should be disclosed. Well registration and abandoned well plugging requirements in Texas are handled through the relevant groundwater conservation district. A cash buyer can take this on; a financed buyer's lender may require it resolved first.
