What Nobody Tells You About Trinity Falls — 8 Facts From the Filings

In the Order the Filings Tell It

1. Your McKinney address pays zero McKinney city taxes

Trinity Falls sits in McKinney’s extraterritorial jurisdiction — outside city limits. No city services line, no city rate (~$0.42 forgone). Sounds like a win until fact 2.

2. A Municipal Utility District taxes you at roughly $1.00 per $100 instead

McKinney MUD 1 (~$0.9875, trending down from $1.019) or MUD 2 ($1.05, flat since 2019), depending on the lot. More than double the city rate it replaces — roughly $5,000 a year on a $500K home, and the bill’s single largest line for most owners.

3. The over-65 freeze never touches it

The shield and ceiling are school-tax instruments; the MUD is not a school tax. A buyer who closes believing "my taxes freeze at 65" has protected the smaller half of this particular bill — the trap in full.

4. Which MUD you’re in is a lot-level fact worth real money

MUD 1’s rate has been stepping down as bonds amortize; MUD 2 has sat at $1.05 for years. The difference compounds over a long hold, and only the lot’s taxing entity list — one page from Collin CAD — tells you which district you are buying into.

5. "The HOA" is two HOAs

A Del Webb sub-association and the Trinity Falls master association both bill. Single-number fee quotes here are how budgets go sideways; demand both schedules itemized in writing before contract.

6. The ~$33K incentive package is real — and it expires mid-2026

Roughly $13K in options money plus $20K flex cash at recent publication. Negotiate every dollar — and then notice it equals only six or seven years of the MUD premium over a comparable city address. Incentives are a discount on the entry; the district is the carry.

7. The MUD financed real things you will use

Fairness requires it: the roads, water, sewer, and amenity infrastructure of a master plan this polished were MUD-bond-funded, and the BorrowedBucks-era pattern across Texas is that district rates do decline as bonds retire. A twenty-year owner will likely watch the rate fall. A seven-year owner should price it as-is.

8. Done right, it still pencils — eyes open

Trinity Falls offers new Del Webb construction, a genuine amenity machine, and mid-$400s pricing the established communities cannot match. The decade carry runs $135K–$145K against the Robson/Frisco Lakes band of $106K–$115K — a premium of roughly $25K–$35K a decade for new-and-now, which some buyers will rationally pay. The only wrong way to buy here is without knowing that number. The sibling alternative with no MUD at all: Trinity Falls vs. Union Park, head to head.
