A buyer closes on a new home in one of Celina's master-planned communities. The payment on the builder's financing sheet looks reasonable, close enough to a resale home a few miles away that the decision feels easy. A few months later, an escrow adjustment notice shows up in the mail. The new monthly payment is several hundred dollars higher than the figure everyone agreed to at the table. Nothing went wrong at closing. The tax bill simply caught up.
That gap is not a builder mistake and it is not a surprise fee. It is a predictable feature of how new construction gets financed in a city growing as fast as Celina, and it is worth understanding before you write an offer, not after your first escrow statement arrives.
The Price Tag Isn't Lying, It's Incomplete
Celina has been the fastest-growing city in the country for two consecutive years, according to U.S. Census Bureau data cited by D Magazine in its reporting on Hillwood's Ramble development. Growth at that pace needs roads, water lines, sewer systems, and drainage in places that had none of it a decade ago. Developers do not wait for the city to build that infrastructure. They finance it themselves through two structures that show up constantly in Celina listings: Municipal Utility Districts and Public Improvement Districts.
Texas Water Code Chapter 54 allows a Municipal Utility District to issue bonds to fund water, sewer, drainage, and road infrastructure ahead of city buildout, then repay those bonds through an added property tax rate that can run for two to three decades. A Public Improvement District funds amenities such as parks, trails, and landscaped entrances through an annual assessment, as described on Celina's Public Improvement Districts page.
Both are legal, common, and not a reason to rule out a community on their own. The problem is that neither one is necessarily included in the number a builder hands you at the sales table, and the online payment estimate you saw before you toured the model home almost certainly does not include it either.
Where This Shows Up on the Ground
This is not an abstract risk in Celina, it is standard practice. The city's own Public Improvement Districts page lists active PIDs including Cambridge Crossing, Chalk Hill, Creeks of Legacy, Edgewood Creek, and Glen Crossing, each governed by its own service and assessment plan filed with the city. Established communities like Mustang Lakes and Light Farms carry district structures that fund their amenity centers and internal infrastructure. And the newest large entrant, Ramble by Hillwood, opened its first phase in May 2026 on 1,380 acres between Preston Road and Custer Road, delivering homes from American Legend Homes, Coventry Homes, Drees Custom Homes, Highland Homes, and Perry Homes across lots ranging from 40-foot in width to a full acre. When the project was first announced, homes were expected to run from roughly $400,000 to $1 million depending on phase and builder, though buyers should confirm current pricing against the specific phase now selling rather than that original range.
A development at that scale, built on raw land two miles north of downtown Celina, is exactly the kind of project that typically requires a MUD, a PID, or both to fund the infrastructure a city that size cannot absorb on its existing tax base alone.
The dollar figures involved are not small. In parts of Collin County, MUD rates commonly run $0.50 to $1.00 or more per $100 of assessed value, which adds roughly $2,500 to $5,000 a year on a $500,000 home. Across the broader DFW new-construction market, combined MUD and PID costs typically add $300 to $400 a month on a $450,000 home, which works out to $40,000 to $50,000 over a decade. PID assessments alone often run $1,500 to $4,000 a year.
How to Actually Check Before You Write an Offer
The information exists, it just does not arrive automatically. Before you sign anything on a Celina new-construction lot, do these four things:
- Pull the property's tax certificate on the Collin County Appraisal District site at collincad.org and look for every taxing entity listed against that specific address, not just the ones the builder mentions.
- Ask the builder or the district's assessment administrator for a projected year-two tax bill once the structure is fully assessed, not only the current land-based estimate used to qualify you.
- Request the PID's service and assessment plan directly from the city for that specific phase. Celina publishes these by district on its Public Improvement Districts page, and the plan will show the actual per-lot assessment rather than a general range.
- Add up total monthly cost yourself: mortgage, base property tax, any MUD rate, any PID assessment, and HOA. Do not rely on the builder's advertised payment or a third-party portal estimate as your final number.
Comparing Ramble, Mustang Lakes, and Light Farms on the Same Basis
This matters more when you are cross-shopping communities that look similarly priced on paper. Mustang Lakes and Light Farms have enough closed transactions and tax history that you can pull actual current bills from Collin CAD and see exactly what a district costs a real homeowner today. Ramble, having opened its first phase in May 2026, does not yet have that track record. For a community this new, ask the developer directly, in writing, for the anticipated per-lot assessment for your specific phase and lot size, since the wide range of lot widths and price points across the community means the proportional tax burden will not be uniform from one homesite to the next.
None of this makes new construction a poor choice in Celina. It makes the sticker price an incomplete number, and incomplete numbers are exactly where good decisions go wrong.
A Few Questions Worth Asking Directly
Will a MUD or PID show up in an online payment calculator? Frequently not in full. Portal estimates commonly reflect only the base property tax rate, which is one more reason to verify the actual taxing entities on Collin CAD before you rely on any number you did not pull yourself.
