If you're buying a home in a Cypress municipal utility district, the seller has to hand you a one-page form titled "Notice to Purchaser of Special Taxing or Assessment District." It names the district and gives one tax rate per $100 of value. Then it lists two sets of dollar figures that most buyers skim past. The first set is the bonds voters have approved. The second is the bonds the district has actually sold.

The rate is the number people compare between subdivisions. The second paragraph is where the future shows up.

The form arrives before the contract, and its rate is already a year old

Texas Water Code §49.452 says the seller must give you this notice before you sign a binding contract, either as a separate document or inside the contract itself. If it shows up late but before closing, your right to terminate can come into play. At closing, a second notice with current information is signed and recorded in the county deed records. The statute text is short and easy to read.

The timing matters because of what the form can and can't tell you in October. Every rate on a Cypress notice today is a 2025 rate, and 2026 rates are being set right now. As of August 13, 2026, the tax assessor's page for Harris County MUD 501 in Towne Lake listed its proposed 2026 rate as "N/A." On September 8, 2026, the board of MUD 500, Towne Lake's master district, had the 2026 rate and a public hearing date on its agenda. Nearby, Cypress Creek Utility District has proposed $0.3959 for 2026, up from $0.393 in 2025, with a hearing on October 8, 2026.

So the rate is already history by the time you read it. The bond figures are more forward-looking, because they show how much borrowing a district can still do.

Towne Lake's notice, figure by figure

HCMUD 501's notice, dated April 1, 2026, reads in part:

The total amounts of bonds payable wholly or partly from property taxes... approved by the voters are: $191,310,000 for water, sewer, and drainage facilities; $66,810,000 for road facilities; and $10,200,000 for parks and recreational facilities.

The same notice lists bonds issued of $25,765,000 for water, sewer, and drainage, $12,670,000 for roads, and $0 for parks. The current rate is $0.5972.

That works out to about $268.3 million approved and $38.4 million sold. The district's April 2026 bond offering document confirms the remainder. After that sale, MUD 501 can still issue $54.14 million in road bonds, $165.545 million for water, wastewater, and drainage, and $10.2 million for parks, "from time to time as needed." State rules cap road bonds at 25% of the district's taxable real property value.

There's a second layer on top of that. MUD 501 is one of four Towne Lake districts that share the debt on regional water, sewer, drainage, park, and road facilities built by MUD 500. Each district's share is based on its assessed value. The master district had $173.3 million of those contract revenue bonds outstanding. MUD 501's notice lists $1,169,810,000 in total authorization for the regional system. That contract obligation was the largest single piece of MUD 501's 2025 rate, $0.39 of the $0.5972.

None of this is unusual for a growing master-planned community. Every new road, pipe, and detention pond gets paid for somehow. The notice tells you how much of that bill is still waiting to be sent.

How a 2009 agreement became a 2026 bond sale

The Towne Lake road bonds also show how that remaining borrowing gets used, sometimes in ways nobody planned for.

My Neighborhood News reported in January 2026 that MUD 501 and Towne Lake's developer, CW SCOA West, L.P., signed a financing agreement in 2009. The developer would front the cost of public roads and landscaping, and the district would repay it later through road bonds. Back then, only major thoroughfares and regional roads qualified, and MUD 500 typically handled those. In 2019, the Texas Legislature widened the definition of road facilities to include public streets and landscaping in rights-of-way. A 2022 Texas Attorney General opinion confirmed that the change applied to existing districts. At its September 3, 2025 meeting, MUD 501's board learned of a $13 million reimbursement request.

The board planned up to about $15 million in road bonds. It agreed with the developer that no interest would be paid on the reimbursement, even though state law usually allows it. The two sides also ended the existing utility and park financing agreements, so this would be the developer's only reimbursement. The final issue closed on May 7, 2026, at $12.67 million. The money covers paving, grading, street lighting, landscaping, and right-of-way land for 16 Towne Lake sections.

Think about someone who bought in Towne Lake in 2018. Their Notice to Purchaser would have shown a road bond authorization they had no reason to worry about. Then a change in state law made a decade-old agreement cover streets that were already built and already being driven on. Voters had approved the borrowing capacity years earlier, and the law change gave it a new use.

What the bond documents say about the debt rate

The offering document also does the math on the new debt. Assuming 2025 values with no growth and no use of cash on hand, MUD 501 would need a debt service rate of about $0.18 per $100 to cover its average yearly payment through 2051. Covering the peak year, 2041, would take about $0.19. The 2025 debt service rate was $0.145.

On $500,000 of taxable value, that gap comes to roughly $175 to $225 a year. That's a scenario, not a forecast. Rising home values, new construction, and the district's fund balances can all close it. As of March 4, 2026, MUD 501 reported $2.68 million in its water, sewer, and drainage debt service fund. The board itself said the rate might change depending on certified values and financial needs, and that it would try to keep any increase small.

The board's next regular meeting is October 7, 2026. Watch for the 2026 rate there.

Fairfield shows a district near the end of its borrowing

Fairfield, a master-planned community a few miles away, shows what the later years look like.

*The Fairfield figures come from year-end 2025 audits. MUD 501's direct debt stood at $31.435 million after the 2026 road bond sale, plus its share of the master district's contract debt.

MUD 354 paid down $703,925 of debt during 2025, ending the year with $1,409,026 left. It has $7.7 million in water, sewer, and drainage bonds that are approved but unsold. Its rate dropped from $0.39 in 2023 to $0.275 in 2024 and stayed there for 2025. MUD 396, in the same community, went from $0.43 to $0.40 to $0.385 over those same three years. It still has $23.355 million approved and unsold, and $9.12 million in debt payable.

Taken at face value, the 2025 MUD rates for 354 and 501 differ by $0.3222 per $100. That's about $1,611 a year on $500,000 of taxable value, before exemptions. The bond figures explain more about which way each rate is likely to move. One district has nearly paid off its debt. The other has borrowed less than a sixth of what its voters approved. For a sense of scale, Cypress-Fairbanks ISD adopted a 2025 rate of $1.0669, so the MUD layer alone can add a quarter to more than half of that school rate again.

A short reading routine for any Cypress notice

1. Subtract bonds issued from bonds approved for each category. A large remainder means the district has room to borrow more, especially if construction is still going on.
2. Look for a contract tax or regional system paragraph. That's where master-district debt shows up, and in Towne Lake it was the largest part of the rate.
3. Check the date at the bottom of the notice. MUD 501's says 4/1/26, and the rate it lists is the 2025 rate.
4. Pull the district's most recent audit or bond offering document. Those show debt payable and the district's own rate projections. The notice only shows initial amounts issued, not what's still owed.
5. In October, look up the 2026 hearing notice or agenda before your option period ends.

The form itself says it plainly: "The cost of District facilities is not included in the purchase price of your property."

A few questions we hear often

Can a MUD issue approved bonds without another election? Yes. MUD 501's offering document says its remaining voter-approved bonds can be issued as needed, and that the district can also issue bond anticipation notes and revenue bonds without a vote.

Is there a cap on the tax rate for these bonds? The notice says the district can levy an unlimited tax rate to pay its bonds. In practice, the board sets the rate each year based on certified values and what the debt requires. This post is general information, so check your own numbers with a tax professional.

Does a low rate mean a district is in better shape? Not by itself. A low rate can mean the debt is nearly paid off, as in Fairfield's MUD 354. It can also mean the borrowing hasn't happened yet.
