Two buyers close on McKinney homes within a few weeks of each other. Both pay right around $550,000. Both think they've done their homework: they compared price per square foot, they walked the same three neighborhoods, they ran the numbers with a lender. Then the first full property tax statement arrives, and one of them owes several thousand dollars more than the other, on a home that cost the same amount to buy.
That gap has nothing to do with negotiating skill. It has everything to do with a line on the county tax bill that most people don't read until they're already living with it: which taxing district the address sits inside.
The Price You See Isn't a Fixed Number to Begin With
Before getting to taxing districts, it's worth admitting that even the "median price" a buyer sees for McKinney depends entirely on which site they're looking at and what stage of the sale it's measuring. Sold-price data from local MLS records through the fourth quarter of 2025 put McKinney's median residential sale price at $440,000, with an average closer to $478,000 once luxury sales in West McKinney and Craig Ranch are factored in. Sale-price tracking through May 2026 put the three-month median closer to $505,000. Active list prices in August 2026 were running higher still, with a citywide median list price around $591,000.
None of those numbers are wrong. They're measuring different things at different moments: homes that already sold months ago, homes that sold more recently, and homes currently sitting on the market waiting for an offer. A buyer who anchors on one number and assumes it describes the whole city is already working with an incomplete picture. And that's before the taxing structure underneath any specific address enters the conversation.
Why a Water District Can Tax You More Than McKinney City Hall Does
Here's the part that catches people off guard. If you buy in Trinity Falls, you are not inside the City of McKinney's taxing jurisdiction at all. The community sits within McKinney Municipal Utility District No. 1 and No. 2, both located in the city's extraterritorial jurisdiction rather than inside city limits. That means Trinity Falls homeowners don't pay the City of McKinney's tax rate. They pay the MUD's rate instead, and it's not small.
McKinney MUD 1's adopted tax rate has actually been declining as bonds get serviced: $0.992525 per $100 of assessed valuation in 2023, $0.987525 in 2024, and $0.9847 in 2025. Compare that to the City of McKinney's own municipal tax rate, which runs around $0.4155 per $100. The MUD rate alone is more than double what the actual city charges for streets and downtown upkeep. Most of that MUD rate isn't discretionary spending either. In 2025, water and sewer debt service accounted for $0.43825 of the rate and road debt service another $0.38150, with only $0.165 going to maintenance and operations. It's almost entirely bond repayment, which is why it doesn't disappear quickly. MUD bonds can take up to three decades to retire.
Layer county taxes (around $0.149 per $100) and McKinney ISD's school rate (around $1.259 per $100) on top of that MUD rate, and a Trinity Falls buyer is looking at a materially heavier annual tax bill than a buyer at the same price point in a community that isn't inside a utility district at all.
The Alternative Structure: A Fixed Fee Instead of a Rate
Not every McKinney community handles infrastructure funding the same way. Some, like Craig Ranch, use a Public Improvement District instead of, or alongside, a MUD. A PID typically works as a flat assessment rather than a percentage of home value, in Craig Ranch's case adding somewhere in the range of $0.15 to $0.50 per $100 for parks and sidewalks specifically. The distinction matters for two reasons. First, a PID assessment is fixed once the bonds are sold, so the homeowner can generally know the schedule from the outset rather than watching a rate fluctuate with reappraisals. Second, PID assessments are widely treated as tax deductible, while HOA dues are not, which changes the math for a buyer weighing two otherwise similar payments.
Then there's a third structure entirely, one with no utility district math at all. Stonebridge Ranch, an established master-planned community inside McKinney's city limits, funds its amenities through a flat annual HOA assessment rather than a bonded tax district. The 2024 flat-rate fee was $953, and the community's governing documents cap annual increases at 5 percent. A buyer here pays standard city, county, and school taxes, full stop, plus a predictable, capped association fee.
Four McKinney Addresses, Four Different Cost Structures
| Community | Funding mechanism | How it's billed | What it typically funds |
|---|---|---|---|
| Trinity Falls | McKinney MUD 1 and MUD 2 (bonded utility district, outside city limits) | Percentage of assessed value, on top of county and school taxes, no city tax | Water, sewer, drainage, and road infrastructure; can run for decades until bonds retire |
| Craig Ranch | Public Improvement District | Fixed assessment, roughly $0.15-$0.50 per $100 | Parks and sidewalks; assessment ends when bonds are paid, generally 20-40 years |
| Stonebridge Ranch | HOA flat-rate assessment, no MUD | Fixed annual fee ($953 in 2024), capped at 5% yearly growth | Pools, trails, and shared amenities; standard city/county/school taxes apply otherwise |
| Historic Downtown McKinney | None; inside city limits | Standard city, county, and school property taxes only | No district assessment; older housing stock predates the master-planned MUD/PID model |
The homes in these four places can list at nearly identical prices. The ongoing cost of owning them will not be identical, and the difference shows up every year on the tax statement, not at the closing table where most people are paying attention.
How to Actually Check Before You Fall for a Floor Plan
The information is public and knowable before you write an offer. It just isn't printed on the listing sheet.
- Pull the Collin County Appraisal District's parcel search for the specific address and see every taxing entity listed, not just the headline property tax line.
- Ask for the district's tax rate history, not just this year's number, since MUD rates shift as bonds are serviced and homes are added.
- If a PID is involved, request the service and assessment plan, which spells out exactly what the assessment funds and when it ends.
- Review the HOA governing documents separately from any district paperwork. A MUD and an HOA are legally distinct, and one dissolving doesn't affect the other.
- Confirm whether the assessment is billed on the property tax statement or separately, since lenders sometimes treat these differently for escrow purposes.
None of this shows up when you're scrolling listings by price. It shows up when someone who already knows which questions to ask pulls the parcel report before you get emotionally attached to a lot.
A Few Questions Worth Settling Early
Does a MUD tax ever go away? The rate can decline as more homes are built and share the debt load, which is exactly what's happened with McKinney MUD 1 over the past few years. Full retirement of the tax happens only once the underlying bonds are paid off, which can take up to 30 years from formation.
Is a PID assessment better than an HOA fee? They fund different things and aren't directly interchangeable, but PID assessments are generally tax deductible while HOA dues are not, which is worth running past a tax professional when comparing two otherwise similar total costs.
Why would two homes on the same McKinney street have different total tax bills? It happens when a subdivision has multiple phases with different assessment terms, or when one home sits on an original "tax value" lot inside an HOA structure like Stonebridge Ranch's while its neighbor has already converted to the flat rate. The lot type isn't always obvious from the listing.
The median price got you interested in McKinney. The taxing district is what determines whether the home you fall in love with actually fits the monthly budget you built around that median.
