A title company ordering a resale certificate on a Stone Oak contract does not always get one invoice back. Depending on the address, it might get two, one from the neighborhood's own homeowners association and a second from the Stone Oak Property Owners Association, the master body that governs the entire master-planned community. On some streets, a third certificate shows up from a separate association that runs nothing but a pool and a clubhouse. None of this appears on the MLS listing sheet. It surfaces later, usually during the option period, when a buyer who assumed "HOA fee: $XXX" was the whole story finds out it was the first of several lines.
This is not a defect in any one listing. It is how Stone Oak was built, and it explains something that a single median price on a housing-data tracker cannot: why two homes that both say "Stone Oak" on the sign can carry different governance structures, different closing costs, and different price trajectories, even when they sit a few blocks apart.
One Name, Two Invoices
Stone Oak is not one homeowners association. It is a master-planned community made up of dozens of individually platted subdivisions, each with its own HOA, all of them layered under a single master association: the Stone Oak POA. If a property sits inside the POA's boundaries, the owner pays a residential assessment to the master association on top of whatever dues the neighborhood HOA charges. The Stone Oak POA's own numbers put that master assessment at $116 a year for residential owners, billed in January with payment due by the end of February. That fee funds the things a single subdivision HOA never would, including the upkeep of roughly 11 miles of landscaped medians that run through the whole community and the architectural review that keeps signage and exterior changes consistent across dozens of unrelated builders.
Some neighborhoods add a third layer. The POA's own FAQ notes that certain subdivisions maintain a separate HOA just to run a private pool or recreation area, meaning a buyer in one of those pockets is technically paying into three associations at once: the subdivision HOA, the pool HOA, and the Stone Oak POA. None of the three replaces the others. Each bills separately, and each shows up on its own resale certificate.
The subdivisions carrying this structure are not abstractions. The Heights at Stone Oak, Canyons at Stone Oak, Champions Springs, and Villages of Stone Oak are all active, named communities inside the POA's boundaries, each with its own covenants and its own board, each still writing a check to the master association every January.
The Split Nobody Updated on the Portal
Sonterra complicates the picture further, and it is the part most buyers never hear until they are already under contract. Real estate listings and neighborhood directories routinely lump Sonterra in with Stone Oak, treating it as another named pocket of the same community. It is not. Sonterra has its own Property Owners Association covering 15 subdivisions and commercial members, and according to the Stone Oak POA's own history page, Stone Oak and Sonterra shared office space and management for years until January 2013, when the two dissolved their partnership and became, in the association's own words, two totally separate entities.
The irony is that Stone Oak's governance still runs through Sonterra's front door. The Stone Oak POA's 2026 annual meeting of members was held at the Club at Sonterra, the clubhouse that belongs to the neighboring, legally separate association. A property owner attending that meeting to vote on Stone Oak business walks into a building that Stone Oak POA does not govern.
For a buyer comparing homes, the practical difference shows up at closing. A Sonterra property's paperwork runs through the Sonterra POA rather than the Stone Oak POA, with its own resale certificate and transfer fee schedule, filed separately with the Texas Real Estate Commission under Sonterra's own management certificate. A Stone Oak POA property runs a different fee schedule entirely. Two homes marketed under the same neighborhood name can close through two entirely different sets of paperwork, timelines, and costs.
| Stone Oak POA | Sonterra POA | |
|---|---|---|
| Subdivisions covered | Dozens of individually platted neighborhoods | 15 subdivisions and commercial members |
| Residential assessment | $116 annually, billed in January | Set by its own board, separate from Stone Oak's schedule |
| Governing status | Independent since the 2013 split | Independent since the 2013 split |
| Meeting location | Annual meeting held at the Club at Sonterra | Governs the Club at Sonterra itself |
| Third-layer HOA possible | Yes, some subdivisions add a pool or rec-area HOA | Governed within Sonterra's own 15-subdivision structure |
What One Median Hides
This governance patchwork lines up with something visible in the price data, and it is the part that matters most to a buyer comparing neighborhoods rather than just comparing houses. Broader housing-market trackers have shown the wider Stone Oak area sitting anywhere from roughly $480,000 to the low $520,000s across different 30-day windows in the first half of 2026, a range wide enough that the trackers themselves do not agree on whether the area's median moved up or down year over year in any given month.
Inside that same MLS footprint, one named subdivision told a much sharper story. Over the three months ending March 2026, The Heights at Stone Oak sold at a median price of $475,000, down 13.6 percent from the same period the year before, with homes averaging 83 days on the market compared to 65 days a year earlier. That is a meaningfully different trend line sitting inside the same neighborhood name that the wider tracker uses to report a flat-to-rising median.
A single blended number cannot show that difference, and it is not because the data is wrong. It is because "Stone Oak" as a label covers subdivisions with different HOAs, different price histories, and in some cases entirely different associations governing the streets around them. A buyer who only reads the headline median is comparing an average of averages, not the specific subdivision they are actually about to write an offer on.
Before You Write the Offer
A few questions are worth asking before a contract goes in on anything marketed as Stone Oak:
- Which HOA governs this specific subdivision, and is the property also inside the Stone Oak POA boundary, the Sonterra POA boundary, or neither
- Is there a third association tied to a pool or recreation area that will show up as a separate line
- What does the resale certificate actually list for assessment amount, transfer fee, and any pending special assessments
- How does the subdivision's own recent sale history compare to the headline number being quoted for "Stone Oak" as a whole
Ordering the resale certificate early, rather than waiting until deep into the option period, gives a buyer time to see exactly which entities are billing and to fold those costs into the offer rather than discovering them at the closing table.
FAQ
Does every home in Stone Oak pay the same HOA fees? No. Each subdivision has its own HOA with its own dues, and residential owners inside the Stone Oak POA boundary pay an additional annual assessment to the master association on top of that.
Is Sonterra part of Stone Oak? Not legally. The two operated together for years but formally split into separate associations in January 2013. They are often marketed together because they sit next to each other and share history, but each is governed and billed independently today.
Why would a subdivision inside Stone Oak have a different price trend than the overall area? Because "Stone Oak" as reported by housing trackers blends dozens of subdivisions with different builders, ages, and buyer pools into one number. A single subdivision's recent sales can move in a different direction than the blended figure without contradicting it.
Buying into Stone Oak means buying into a specific subdivision first and a neighborhood name second. The governance layers, the fee schedules, and the recent price history all live at that subdivision level, not at the level of the sign on the parkway.
