What Nobody Tells You About Del Webb at Union Park — 8 Facts

In the Order They Hit Your Budget

1. The HOA quote you receive is missing the second HOA

Del Webb’s sub-association bills $429 a quarter (~$143/month). The Union Park master association bills $120–135 a month on top. The combined charge of ~$263–278/month is the real number; single-layer quotes that circulate in listing descriptions and buyer conversations understate the carrying cost by nearly half the HOA line. Both associations exist, both bill, neither is optional.

2. "Little Elm" on your address does not mean Little Elm ISD

The community sits in Little Elm with a Little Elm mailing address. The school district serving the 55+ section is Little Elm ISD — but confirm the specific street’s district assignment before pricing anything. Parts of the broader Union Park master plan cross into different ISD territories, and rate spreads in this area are real money annually.

3. The over-65 math here is the best in the Del Webb lineup

Mid-$300s entry means the flat $200K senior shield erases roughly 53% of your school-taxable value — the highest ratio of any major Del Webb community in DFW. The school line then freezes on a very modest remaining base. The budget benefit of buying at this price point rather than Trinity Falls at mid-$400s is compounding over every year of ownership.

4. The community is nested inside a family master plan

Union Park is the 55+ enclave within the larger Union Park master-planned community. The master HOA funds shared infrastructure the whole development uses — including the amenities your grandchildren will enjoy far more than the retirement calendar events. The dual-HOA is partly a consequence of this nesting structure. For buyers who want a sealed 55+ world, the nesting model delivers something different: a multigenerational neighborhood with an age-restricted pocket inside it.

5. PIDs exist in this corridor — your lot\u2019s entity list is not optional

The Little Elm growth belt carries Public Improvement District assessments by development section. Union Park’s core 55+ section may or may not carry one — the only way to know is the lot’s taxing entity list from Denton CAD, requested before contract. This is the trap the Over-65 Guide names specifically: special district assessments ignore every senior protection and ride appraisals forever.

6. Trinity Falls is twenty minutes away and carries a MUD

Buyers comparing Del Webb options in the northern corridor frequently consider both Union Park and Trinity Falls. The structural distinction that dwarfs all others: Trinity Falls sits outside McKinney city limits served by a MUD at ~$1.00/$100 that ignores the over-65 freeze; Union Park has no identified MUD on current listings. The decade comparison puts that difference at ~$30,000–$40,000 in Union Park’s favor over ten years.

7. It is still building — which is the opportunity and the caveat

New Del Webb construction means warranty coverage, design center choice, and current incentive packages — but also construction traffic, phased opening of amenities sections, and the builder-to-resident HOA handoff that often coincides with the first fee increase. Get the current incentive package in writing and understand which amenities are fully operational versus under development at the time of contract.

8. Denton County is the quiet tax advantage

The Del Webb brand spans Collin and Denton counties in DFW. Union Park sits in Denton — which means no hospital district on the tax bill (~$0.22/$100 savings versus the Tarrant County baseline) and filing through Denton CAD. In a decade of ownership that hospital-district absence saves a Tarrant-equivalent household $8,000–$12,000 in floating levies. The full picture: Union Park true cost · Denton County guide
