Two identical Trinity Falls floor plans can sit half a mile apart, price the same on the listing sheet, and still carry a different tax bill every single year. Not because of school ratings or lot size. Because of which side of an invisible line they happen to sit on.
Trinity Falls looks like one community from the road. On paper, it's two.
A Community Split Between Two Tax Districts
Trinity Falls sits inside McKinney Municipal Utility District No. 1 and McKinney Municipal Utility District No. 2, and the two districts do not charge the same rate. Under MUD 1's 2025 adopted rate, the most recent on file, the district levies $0.9847 per $100 of assessed value, split across maintenance and operations, water and sewer debt service, and road debt service. MUD 2's 2025 adopted rate runs $1.05 per $100, broken into a similar three-part structure but weighted differently, with a larger share going toward water and sewer debt.
That gap sounds small until you attach it to a real home. On a $500,000 house, MUD 1's rate works out to roughly $4,924 a year. The same house in MUD 2 runs about $5,250. Push the price point up toward Trinity Falls' higher-end estate homes, closer to $900,000, and the annual gap between the two districts grows to nearly $590, because both rates scale with the home's assessed value rather than staying fixed.
That scaling matters more than the dollar figure itself. A Public Improvement District, the financing tool used in several other McKinney and Celina communities, typically locks in a flat per-lot assessment at the time the bonds are sold. It doesn't move with home value, and a homeowner can pay it off early and remove it from the tax bill permanently. A MUD tax doesn't work that way. It rises and falls with the appraisal district's number every year, for as long as the district carries debt.
The Line Between the Districts Isn't on the Marketing Map
Here's the detail that rarely makes it into a listing conversation: McKinney MUD 2 holds its board meetings at the Del Webb Amenity Center, the clubhouse built for Trinity Falls' age-restricted 55-plus section. That's not proof every Del Webb lot sits in MUD 2, but it's a strong signal that the district lines run through the community in a way that has nothing to do with builder brand, phase name, or price point.
The two districts jointly encompass the Trinity Falls residential community, according to MUD 2's own public filings. Which one applies to a specific address isn't something a buyer can guess from the street name.
If you're comparing two Trinity Falls listings, or comparing Trinity Falls to a neighboring community, the district a given lot sits in is worth confirming before you compare payments, not after.
Why the City Isn't Part of This Bill at All
There's a reason Trinity Falls' tax picture leans so heavily on MUD math in the first place: the City of McKinney has no property tax jurisdiction here. The community sits in the city's extraterritorial jurisdiction, outside its formal boundary, which means residents pay no city tax line at all. The infrastructure that a city tax would normally fund, streets, water lines, drainage, gets financed instead through the district's own bonds and repaid through the MUD tax rate.
That trade cuts both ways. No city tax is a genuine savings compared to a home inside McKinney's incorporated limits. But the MUD rate that replaces it is also considered a property tax for IRS purposes, which means it behaves like one on the appraisal roll: it scales with value, it shows up every year, and it doesn't disappear once you've paid it off the way a PID lien can.
The Rate Direction That Only Shows Up If You Track It Year Over Year
MUD 1's adopted rate has stepped down in each of the last three years on file: $0.992525 in 2023, $0.987525 in 2024, and $0.9847 in 2025. That's the pattern district officials point to when they explain how MUD financing is supposed to work: as bond debt gets retired and more homes come online to share the operating and debt service costs, the rate per $100 should ease downward.
MUD 2 hasn't followed the same path over the same window. Its rate held at $1.05 across both 2023 and 2025, flat rather than declining. Both districts are still building out, both are still adding rooftops, and both carry the same stated commitment to lower the rate when the numbers allow it. They're just not moving at the same pace, which means a lot's tax trajectory over the next five years depends on which district it sits in, not just on how the community as a whole is trending.
What a Flat "Trinity Falls Price Range" Actually Papers Over
Layer the district split on top of Trinity Falls' builder lineup and the picture gets more complicated, not less. The community's own builder page counts seven partner builders, including Del Webb's age-restricted 55-plus section. Individually, listings tie names like Ashton Woods, Beazer, Highland Homes, Meritage, Chesmar, and Coventry to different sections and price tiers across the community, with the overall range running roughly the $400s up through the $900s and beyond for the largest estate sections. Chesmar's Trinity Falls section has listed a starting price of $589,990. One new-home marketplace has listed entry-level inventory in the community starting as low as $338,990.
A single "Trinity Falls median price" quoted on a portal search averages across all of that: a starter home from one builder, a Del Webb 55-plus plan, and a river-lot estate from another builder entirely, each carrying a different MUD exposure depending on where its lot falls. Two buyers comparing the same headline price range can end up looking at genuinely different monthly numbers once taxes are added in.
What This Changes If You're Comparing Trinity Falls to a PID Community
For a buyer cross-shopping Trinity Falls against a community that finances its amenities through a Public Improvement District instead of a MUD, the comparison isn't as simple as stacking one line item against another. A PID assessment is fixed at closing, doesn't move with appraised value, and can be paid off and removed for good. A MUD tax moves with the county's valuation every year and keeps applying for as long as the district carries debt, though it can also decline as that debt shrinks, the way MUD 1's rate has in each of the last three years on file.
That means the honest comparison isn't "which number is bigger today." It's "which trajectory do you want to be exposed to." A buyer planning to stay ten or fifteen years might prefer a district with a demonstrated pattern of falling rates. A buyer more focused on a predictable, fixed number might lean toward a PID structure instead, even if the flat assessment looks larger on day one.
Before You Compare Two Listing Sheets
A few things worth confirming before treating any two Trinity Falls listings as apples to apples:
- Which MUD district the specific lot sits in, MUD 1 or MUD 2, since the rate difference is real and compounds with home value.
- Which builder section the home belongs to, since price points across the seven builders vary enough that "Trinity Falls" alone tells you very little about what you're actually being asked to pay.
- Whether the district's rate has been trending down or holding flat over the past few years, since that trajectory says more about your long-term carrying cost than the current year's number does on its own.
None of this shows up automatically on a listing sheet. It takes a phone call, a look at the appraisal district record, or a conversation with someone who tracks these district filings as part of working this specific market.
Frequently Asked Questions
Does every Trinity Falls home pay both MUD 1 and MUD 2 taxes? No. The two districts jointly cover the community, but a given lot falls within one district's boundary, not both.
Are Trinity Falls' MUD taxes deductible the way property taxes are? Yes. The districts' own materials note that these levies are treated as property taxes for IRS purposes, the same treatment as a standard county or school tax bill.
Will the MUD rate keep declining every year? Not automatically, and not evenly across both districts. MUD 1's rate has stepped down in each of the last three adopted years through 2025. MUD 2's rate, by contrast, held flat at $1.05 in both its 2023 and 2025 adopted filings. Each district's trajectory depends on its own remaining bond debt and how quickly new homes join to share the cost.
If you're weighing a Trinity Falls floor plan against something in Stonebridge Ranch, Painted Tree, or another McKinney-area community, the district a specific lot sits in is one of the first things worth checking, not the last.
