The Number Prosper's New-Construction Price Tags Leave Out

Two model homes, same builder tier, same square footage, same $600,000 price stamped on the sign out front. One sits in Artesia along US-380. The other sits in Mosaic, a few miles up the growth corridor toward Celina. A buyer touring both on a Saturday afternoon could walk away thinking the choice comes down to floor plan and lot size.

It doesn't. The number that actually separates these two homes never makes it onto the sign. It shows up months later, on the first property tax bill, and it can run two or three hundred dollars a month apart depending on which financing tool built the streets, sewers, and lakes those homes sit next to.

That tool has a name. Sometimes it's a Municipal Utility District. Sometimes it's a Public Improvement District. Almost nobody shopping new construction in Prosper asks about it before they fall in love with a kitchen island.

Two Ways to Pay for the Same Infrastructure

Every new master-planned community needs water lines, drainage, roads, and increasingly, the parks and lakes that make the brochure photos work. A developer building outside the reach of existing city infrastructure has to fund all of that before a single house closes, and the two standard tools for doing it work very differently.

A Municipal Utility District, created under the Texas Water Code and overseen by the Texas Commission on Environmental Quality, issues bonds to build the infrastructure and then repays them through an ongoing property tax levied on every home inside the district. Artesia runs on this model. A 2025 tax record for an Artesia home showed a property tax bill of $13,361 on a $586,000 assessed value, plus HOA dues of $516 a year, with the parcel carrying separate MUD charges for sewer and water. Across Prosper-area MUDs generally, published mid-2026 figures put the added rate at roughly $0.20 to $0.65 per $100 of assessed value on top of the standard city and county rate, which on a $550,000 home works out to somewhere between $1,100 and $3,575 a year depending on where that community sits in its bond repayment schedule.

A Public Improvement District, authorized under Chapter 372 of the Texas Local Government Code, works differently. Instead of an ongoing tax rate, it charges a fixed special assessment tied to the cost of specific amenities, typically repaid over 20 to 30 years. Mosaic runs this way. Its PID assessments fund landscaping, lakes, fountains, parks, shade structures, and pedestrian paths across the community, and the total published tax rate there runs about 2.04%, which comes to roughly $11,220 a year in total property taxes on a $550,000 home before HOA dues are even added. Mosaic's HOA runs $148 a month for single-family homes and $438 a month for townhomes.

Neither structure is a defect. Both let a developer build the kind of amenity package that competes for buyers without pricing the base home out of reach on day one. A community with $30,000 of enhanced landscaping and open space per lot can either fold that cost into the sale price today or spread it across a quarter century of assessments. Developers routinely choose the second option because it keeps the advertised price competitive against a neighbor who built more cheaply and skipped the lake.

The Address Doesn't Always Match the Taxing Authority

Here's where it gets easy to miss. Light Farms, a community that draws a lot of family buyers to the area, sits directly across the line where Prosper meets Celina, and its MUD financing follows the actual boundary of the district, not the marketing label on the entrance sign. Mosaic markets itself into that same Prosper-Celina growth corridor. The lesson isn't which side of a line either community falls on. It's that "Prosper" as a search term and mailing address covers ground that sits under several different taxing authorities, and the financing tool attached to a given lot depends on which one actually built the pipes underneath it, not on which town name shows up on the community's welcome sign.

That's a question worth asking directly, because the answer changes what a tax certificate will show for the life of the loan.

The Communities Betting the Other Way

Not every builder in the area uses either tool. Windsong Ranch funds its common areas and lifestyle programming through a standard HOA rather than a MUD or PID. Star Trail bills its HOA dues quarterly with no special district attached. Dominion at Brookhollow runs an HOA at $133 a month and carries neither a MUD nor a PID.

Lined up against each other, the math tells a clearer story than any single number does on its own. Using recently published figures built on the same kind of tax and HOA records cited above, a $600,000 home in a no-MUD, no-PID community like Dominion runs about $13,536 a year in combined taxes and HOA dues. A comparable $600,000 home in Mosaic, where the PID funds the lake and trail system, runs closer to $16,096 a year, about $213 more a month. The gap narrows considerably for a MUD community: an Artesia-style home at roughly $13,871 a year in taxes and HOA lands only about $51 a month above the no-district comparison.

The takeaway isn't that one structure is better. It's that the same $600,000 price tag can carry three different real monthly costs depending entirely on which financing tool sits behind the address, and the size of that gap is large enough to change a mortgage qualification conversation.

These Tools Have a Lifecycle

One town over, Frisco is already living the back half of this story. As of March 2025, the city was in the process of closing out its original PID 1 and PID 2, the districts that financed some of its earlier master-planned growth. That's the natural end state for a well-run district: the improvements get built, the bonds get retired, and the special charge eventually disappears from the tax bill.

Prosper's active MUDs and PIDs are still early in that cycle, which means the assessments a buyer sees on a 2026 tax certificate reflect a community still paying down its original infrastructure debt, not one coasting on a paid-off system. That's useful context for anyone assuming the number they see today is close to its final form. It usually isn't, at least not for another decade or two.

A builder's price sheet tells you what the home costs to buy. It says nothing about what the district behind it will still be billing you in year eleven.

What Follows the House at Resale

Texas law requires that a MUD or PID be disclosed to a buyer before closing, whether through the seller's disclosure or a separate notice, and builders selling new construction are required to disclose the same information. That protects the next buyer from surprise, but it also means the obligation follows the house. Whoever buys from you down the line will see the identical assessment on their tax certificate, calculated the same way, tied to the same bond schedule. A PID assessment is a fixed lien that can be paid off in full at any point if an owner wants to clear it before selling. A MUD tax generally can't be paid off early in the same way. It simply continues until the district's bonds are retired, which is the same lifecycle Frisco's PID 1 and PID 2 have been winding down toward.

Questions Worth Asking Before You Compare Two Price Tags

• What is the total combined tax rate on this specific address, not just the base city and county rate?
• Is the property inside a MUD, a PID, both, or neither, and which government body actually authorized it?
• How many years remain on the bond or assessment schedule, and has the district published that timeline?
• What does the HOA cover here that a PID might be funding in a neighboring community, and does that change what the HOA fee actually buys?
• What will a title company's tax certificate show a future buyer, and how does that compare to a similarly priced home without a special district?

A Few Direct Answers

Does a MUD tax ever go away? It generally continues until the district's bonds are repaid, which can take decades, and even after that the maintenance and operations portion typically remains to cover ongoing utility upkeep. It rarely drops to zero.

Can I pay off a PID assessment early? Usually yes. A PID assessment is a fixed lien, and owners can pay off the remaining balance in full at any time rather than continuing the annual installment.

Does having a MUD or PID mean a home is a worse deal? Not by itself. It means part of the community's cost sits in the tax bill instead of the sale price. The only way to know which arrangement actually costs less for a given household is to run the combined number, not just compare the price on the sign.

Comparing two builder price sheets in Prosper takes more than a calculator for square footage. It takes knowing which taxing authority stands behind each address and what that authority is still collecting on. That's the kind of detail that only shows up when someone pulls the actual tax certificate rather than the marketing brochure, and it's the difference between comparing two homes and comparing two very different long-term obligations that happen to look identical on a Saturday afternoon.
