Sellers in Cypress brace for the wrong villain. They worry about the inspection report flagging a hairline crack in the garage slab. They worry about the appraisal coming in short. They worry about a buyer's financing falling through in the final week. All reasonable fears, and all mostly out of a seller's hands once a contract is signed.
The document that actually has the power to unwind a signed Cypress contract, right up to the morning of closing, is a one-page government form almost nobody outside a title office calls by name: the Notice to Purchaser of Special Taxing or Assessment District. It covers a Municipal Utility District, or MUD, and Texas law treats it as a live trigger, not a formality filed away with the rest of the closing packet.
What the Law Actually Requires
Texas Water Code Chapter 49 requires the seller of any property inside a MUD to hand the buyer a specific written notice before the contract is signed, not after. The notice has to state the district's tax rate, its bonded indebtedness, and any standby fee, and it has to carry the header "NOTICE TO PURCHASER OF SPECIAL TAXING OR ASSESSMENT DISTRICT" in type no smaller than 24-point bold, a detail the Texas A&M Real Estate Research Center points out specifically because sellers so often miss it.
The Texas Legislature rewrote the requirement in 2023. Two bills, HB 2815 and HB 2816, took effect in June and September of that year and repealed the old fixed-form notices in favor of a single set of required content under Section 49.4521. There is no more pre-printed template to grab and reuse. The information in the notice has to be current to that specific district, which is where Cypress sellers run into trouble.
Why the Same Neighborhood Can Carry Two Different Tax Bills
Cypress is unincorporated. There is no city hall collecting a city tax, which means the MUD is doing work a city government would otherwise do: financing water, sewer, drainage, and roads through bonds that get repaid on the tax bill. Large master-planned communities rarely sit inside a single MUD. Bridgeland and Towne Lake are each carved into multiple districts, and each district carries its own bond position and its own rate.
That produces a spread most buyers never see coming. Within Towne Lake, the original district and a newer one on the opposite side of the community have historically run well over half a percentage point apart in combined rate, same amenities, same schools, materially different monthly payment. Across the broader area, the pattern holds:
- Bridgeland: combined rates commonly run in the 3.0% to 3.4% range depending on section and MUD, with newer villages toward the top of that band
- Towne Lake: a similar overall range, but split unevenly between its original and newer districts
- Fairfield and Coles Crossing: generally lower, often in the mid-2% range, because those districts have had more years to pay down bond debt
On a $500,000 home at 3.2%, that is roughly $16,000 a year before any homestead exemption. On a comparable home in an older, paid-down section, the same math can land closer to $12,000. Two houses can list for the same price and carry a monthly tax difference of $300 or more, which is exactly the gap a generic mortgage calculator does not know to account for. The Harris County Appraisal District is the source of record for confirming which district applies to a specific address.
The District Isn't Standing Still
It is tempting to treat a MUD's tax rate as a fixed historical fact, something set once when the district formed and left alone. Cypress is proof that isn't how it works.
Harris County MUD 500, which serves Towne Lake, has spent years coordinating a genuine infrastructure project: extending Greenhouse Road north of Mound Road to connect to US-290, alongside a new underpass pump station and a fire station site planned near the Greenhouse Road and Mound Road intersection. According to the district's own public filings, TxDOT awarded the construction contract to Harper Brothers on February 28, 2026, with a pre-construction meeting scheduled for early May and construction expected to begin that summer and continue through late 2029 or early 2030.
That is an active, multi-year, bond-adjacent project running right now, not a line item from a decade-old master plan. Districts that are actively building carry different obligations than districts that finished their infrastructure years ago and have simply been servicing debt on a predictable schedule. A MUD Notice photocopied from a neighbor's sale, or pulled from a seller's own purchase file a few years back, does not reflect that. It has to be current to the district's latest published information, which is precisely why the 2023 rewrite tightened the requirement instead of leaving it alone.
What Happens If the Notice Is Wrong or Missing
Here is the part that catches experienced sellers off guard. The buyer's right to walk away over a missing or defective MUD Notice does not close out at the end of the option period. It survives all the way to the closing table.
The clock does not stop at the option period. It stops at the closing table.
If a seller never delivers the notice, the buyer can terminate the contract at any point before closing and recover their earnest money. If the seller catches the mistake and delivers a corrected notice before closing, and the buyer proceeds to close anyway, the buyer is presumed under the statute to have waived both the termination right and any damages claim. That waiver only covers a notice that was late but eventually correct. It does not retroactively excuse a notice that was inaccurate or incomplete when it finally arrived.
Texas law also gives a wronged buyer a narrow window to sue after the fact: a damages claim under the statute has to be filed within 90 days of the buyer receiving the district's first tax notice, or within four years of the sale, whichever comes first. That is not a long runway, which is one more reason sellers benefit from getting the notice right the first time rather than relying on a later cure.
Before You List in Bridgeland, Towne Lake, Fairfield, or Coles Crossing
None of this makes a MUD a reason to avoid Cypress. MUDs are the financing mechanism that built the roads, water lines, and drainage for nearly every master-planned community in this part of Harris County, and buyers here generally expect to see one. The Texas Real Estate Commission's own notice form exists precisely because the requirement is common enough to standardize.
The practical move for a seller is straightforward: confirm the correct district for the exact address, pull the district's current notice rather than an old one, and have that figure checked against the Harris County Appraisal District before the contract goes out. For a home inside a district with active construction underway, that verification matters even more, because the numbers a buyer finds three months from now on their own tax statement need to match what they signed off on in the notice.
If you are weighing new construction against resale in Cypress, or comparing a Bridgeland section against Towne Lake or Fairfield, the tax structure is part of the real cost of ownership, not a footnote to it. Callis & Co Realty works through that math on a per-address basis as part of buyer and seller guidance across Cypress and the wider Houston area, including our new construction guidance for buyers comparing builder communities.
A Few Direct Questions
Does the MUD Notice apply to resale homes, or only new construction? It applies to any conveyance of property inside a district's boundaries. The obligation is not limited to the builder's original sale.
What if the property sits in both a MUD and a Public Improvement District? Both notices are required, and one does not substitute for the other. A MUD Notice covers tax rate, bonded debt, and standby fees under the Water Code. A PID notice covers assessment amounts under a separate section of the Local Government Code.
Can closing still happen if the notice went out late? Yes, if the seller delivers a corrected notice before closing and the buyer chooses to proceed. That closes out the termination right for lateness alone. It does not cover a notice that still gets the numbers wrong.
If you are preparing to list, or you are under contract on a home in one of Cypress's master-planned districts and want the tax picture confirmed before you sign anything else, reach out to Callis & Co Realty. Let's connect and get the numbers right before they become someone else's problem at the closing table.
