Texas doesn't require sale prices to be recorded as public record. That single fact means every price tracker watching Prosper right now, Redfin, Zillow, Movoto, the independent data firm Resideline, is working from a different partial slice of the same market. None of them sees every closing. So when a buyer pulls up four sources in the same afternoon and gets four different answers about what's happening in Prosper, the disagreement isn't a glitch. It's baked into how Texas real estate data works.

But that alone doesn't explain the size of the gap. Redfin's numbers show Prosper home prices down 11.5 percent year over year as of March 2026, with price per square foot down an even sharper 13.5 percent to $236. Zillow's Home Value Index, a different kind of measurement built by tracking the same properties over time rather than whatever happened to close that month, showed a much gentler 5.8 percent decline as of June 2026. Movoto's April 2026 snapshot put the median sale price at $863,843, higher than what Redfin was reporting for the same general window. Resideline's trailing six-month figure through August 2026 landed at $849,900 across 477 tracked closings.

Those aren't rounding differences. They're evidence of something specific happening to what's actually selling in Prosper right now, and the reason traces back to a zoning vote the town council made a year ago.

Four Trackers, One Town

The pattern worth sitting with is that the index built to smooth out month-to-month noise, Zillow's, shows the mildest decline. The raw monthly medians swing much harder. That's the signature of a market where the mix of what's closing is changing, not one where existing homes are simply worth less. A repeat-value index tracks the same houses over time. A monthly median just reports whatever closed, and if a different shape of home starts closing in volume, the median moves even though no individual owner lost equity.

One live MLS-sourced report from April 2026 makes the skew even clearer, showing an average sale price of $979,416 against a median in the $860,000s. That gap between average and median is a signature of luxury closings in established communities like Star Trail, Whitley Place, and Gentle Creek Estates pulling the average up while a growing wave of smaller-footprint product pulls the median and per-square-foot figures down. Both things are true in Prosper at the same time.

The Vote That Changed What Gets Built

In August 2025, Prosper Town Council voted 5-2 to amend the development plan for Gates of Prosper, one of the town's largest mixed-use developments at Preston Road and US 380. Deputy Mayor Pro Tem Chris Kern and council member Marcus Ray voted no. The Planning and Zoning Commission had unanimously recommended denying the changes before council overruled that recommendation.

The amendment did two things. It added 600 multifamily units to Subdistrict 2, bringing that district's total to 1,200 units, with a condition capping two-bedroom apartments at 37 percent of the total and requiring the rest to be one-bedroom. And it converted Subdistrict 3, originally planned as a downtown center of offices and mixed-use buildings, into 150 additional single-family lots, doubling that district's home count to 300.

Blue Star Land, the developer behind Gates of Prosper, made its case plainly through engineering director Scott Shipp, who argued that landing high-end retail and restaurant tenants in Prosper depends on having enough rooftops nearby to support them. Mayor Pro Tem Amy Bartley summed up the tension council was navigating: residents kept saying they didn't want more multifamily, but they also wanted the upscale retail that only comes with density. Ray disagreed with the trade, saying he had "significant heartburn" with the volume of multifamily being added. Kern's objection was about precedent, worrying the town was giving away its negotiating leverage on future projects.

By May 2026, 256 of those 600 approved apartment units were already under construction. That's the timeline that matters here. A vote from a year ago is only now working its way into what closes and what gets counted in a median.

Council Has Been Consistent About One Thing

Development Services Director David Hoover has said publicly that multifamily construction in Prosper is only realistic in three places: downtown, along the Dallas North Tollway, and the Town Center district that Gates of Prosper occupies. Mayor David Bristol has been equally consistent that his preference is to cap additional multifamily along the tollway corridor specifically, treating it as the town's release valve for density rather than something to spread across every parcel.

In 2024, a year before last summer's Gates of Prosper amendment, council raised the maximum allowed height for multifamily buildings from three stories to eight, as one of twelve amendments approved that day to the town's multifamily standards ordinance, including a rule that multifamily can only be approved within a planned development district in the first place. Hoover has framed the overall approach as managing a "density equation," with a standing expectation that each new project has to be better executed than the one before it.

None of this reads like a council throwing open the gates. It reads like a group extracting specific, negotiated concessions, upscale retail commitments, unit-type caps, height limits tied to location, in exchange for each increment of density. That negotiation, project by project, is exactly why Prosper's housing stock is changing shape unevenly instead of uniformly.

What's Still Being Argued Over

Not every project has landed the way Gates of Prosper did. A few for comparison:

• Bella Prosper, a 62-acre mixed-use proposal with 271 multifamily units and 116 townhomes, has been tabled by council multiple times since first appearing in November 2025, most recently pushed to a June 2026 hearing.
• Prosper Oaks, a 373.5-acre proposal off Parvin Road for up to 775 homes, was tabled repeatedly after Planning and Zoning unanimously recommended denial over density and lot-size concerns, before council ultimately approved it in October 2025.
• Merritt Crossing, a 335-unit apartment community on the Prosper-Celina border, is under construction, with a May 2026 update targeting initial move-ins for this summer.
• Mirabella, a 190-acre gated community from Highland Homes and Tellus Group near US 380 and Custer Road, broke ground in September 2025 with 290 homes across a range of lot sizes, and is expected to open for sales later this year.

Some of these add density with resistance. Some add it with none. Some are still homes on individual lots, just smaller and more varied than what Prosper built five years ago. Every one of them will eventually show up as a closing, and every one of them will nudge the citywide median in a slightly different direction depending on when it closes and what it looks like.

Reading Prosper's Numbers Going Forward

If you're comparing Prosper to Frisco or McKinney using a single median price, you're comparing a number that's currently absorbing all of this at once. Days on market have stretched, Redfin puts it at 98 days as of March 2026 versus 83 a year earlier, and one MLS-sourced report shows 7.3 months of supply in April 2026, which shifts real leverage toward buyers in some segments. But that leverage isn't evenly distributed. A buyer looking at an established large-lot section like Star Trail or Gentle Creek Estates is shopping a different supply curve than a buyer looking at new inventory closer to Gates of Prosper.

The practical move is to stop treating the citywide median as a verdict on Prosper and start asking which of these product types a specific listing belongs to. A three-year-old home on a quarter-acre lot in an established section isn't competing against a new townhome twenty minutes away, even if a spreadsheet lumps them into the same number.

Two Questions Worth Asking Before You Trust a Median

Does a falling median mean Prosper homes are losing value? Not necessarily. The property-level index tracking the same homes over time has moved far less than the raw monthly medians, which is the pattern you'd expect when new, differently priced product enters the mix rather than existing homes losing worth.

Will more apartments near Gates of Prosper affect resale value in established neighborhoods? The town's own zoning conditions, including the two-bedroom unit cap and requirement that new hospitality and retail tenants be upscale, were negotiated specifically to protect the character council wanted nearby. How that plays out for any individual subdivision is worth a conversation grounded in that property's specific location relative to the district.

Prosper's numbers are going to keep looking unsettled for a while, because the town itself hasn't settled what it's building next. If you're trying to make sense of a specific address rather than a citywide average, that's a conversation worth having before you rely on any single tracker.
