Two Fair Oaks Ranch homes can share a floor plan, a builder, and a street name, and still arrive at closing with different property tax bills, different appraisal notice dates, and a different number of envelopes in the November mail. The reason has nothing to do with square footage or upgrades. It has to do with which county line the foundation happens to sit on.
If you are under contract in Fair Oaks Ranch, or close to it, this is the piece of due diligence that most portal-driven searches skip. The thesis is simple: in this city, the county boundary under a home is a larger driver of first-year carrying cost surprises than the sale price itself, and the medians published on national real estate sites obscure the effect rather than explain it.
The map that isn't on the MLS listing
The City of Fair Oaks Ranch lies within three counties, Bexar, Comal and Kendall, and by law appraisals are conducted by the county where the property is physically located. That single sentence is the beginning of every complication that follows. The City sets one municipal rate. Each county sets its own appraisal calendar and its own protest deadline. Each school district that reaches into the city collects on its own schedule.
For fiscal year 2025-26, the City Council adopted a municipal property tax rate of $0.2853 per $100 of taxable value, a rate that the adopted ordinance notes will effectively raise maintenance and operations revenue by 5.49% over the prior year. The rate itself is not the interesting part. The interesting part is the collection mechanic: the City contracts with the Bexar County Tax Office for the billing and collection of all city property taxes, regardless of the county of residence, and city tax statements are mailed in October and become delinquent the first day of February.
So a Kendall County homeowner in Fair Oaks Ranch still receives a Bexar County envelope every fall. It is easy to assume a mistake and set it aside. It is not a mistake.
Three billing scenarios, side by side
The number of separate bills a Fair Oaks Ranch owner receives depends entirely on which county and which school district their address falls into. The City of Fair Oaks Ranch property tax servicing page lays out the combinations. Here is what actually lands in the mailbox:
| Where the home sits | Appraisal notice from | Bills received in November |
|---|---|---|
| Bexar County, Boerne ISD | Bexar Appraisal District | Bexar TAC (Bexar County + city + other Bexar entities); Kendall AD (Boerne ISD) |
| Kendall County, Boerne ISD | Kendall Appraisal District | KAD (Boerne ISD + Kendall County); Bexar TAC (city) |
| Comal County, Comal ISD | Comal Appraisal District | Comal TAC (Comal County + Comal ISD); Bexar TAC (city) |
| Comal County, Boerne ISD | Comal Appraisal District | Comal TAC (Comal County); Kendall AD (Boerne ISD); Bexar TAC (city) |
That last row is the one the City itself flags. Some Comal County residents live within the Boerne Independent School District boundaries, so they receive a bill from the Comal County Tax Assessor-Collector for their Comal County property taxes, a bill from Kendall AD for their Boerne Independent School District taxes, and a bill from the Bexar County Tax Assessor-Collector for city taxes. Three envelopes, three deadlines, three offices to call when something looks off.
For a physician or military family relocating on a compressed timeline, this matters less as trivia and more as operations. A lender's escrow analysis has to enumerate every taxing unit correctly the first time. When it doesn't, the shortage shows up in year two, usually in a letter that raises the monthly payment without warning.
The number the portals are not showing you
Ask three sites for the Fair Oaks Ranch median price and you will get three different answers, because they are not measuring the same geography. Recent snapshots put the city-level median sale price at roughly $774,500 in May 2026, up more than 11% year over year, while the broader 78015 ZIP code, which spills well outside the city limits, shows a median listing closer to $637,000. Movoto's April 2026 read on the city put the median at $712,000 with about 51 days on market, down from 62 days a year earlier.
Those figures are all technically accurate. They also describe different places. A move-up buyer benchmarking their budget against the ZIP-code number is planning for a house that is not, on average, inside the city of Fair Oaks Ranch. That distinction shapes not only price expectations but which appraisal district will send the first notice next April.
The first-year escrow trap
The friction that catches buyers off guard is rarely the total tax bill. It is the timing and the composition. A representative Fair Oaks Ranch homeowner on the Kendall side carries a median annual bill of about $10,390 at an effective rate near 1.01%, while Bexar-side bills across the city commonly range from roughly $10,300 at the 25th percentile to more than $15,600 at the 90th, according to Ownwell's tracking. The spread within the same city is wide enough that a lender working from an incorrect county assignment can underestimate the escrow requirement by thousands.
Before closing on a Fair Oaks Ranch home, verify the following in writing:
- Which county appraisal district the parcel sits in, confirmed by the district's own parcel search rather than the listing agent's data sheet. The three districts are Bexar Appraisal District, Comal Appraisal District, and Kendall Appraisal District.
- Which school district the address falls within, because Boerne ISD and Comal ISD reach into different parts of the city and their rates are not interchangeable.
- That the lender's escrow analysis includes a separate line for the city portion collected by Bexar TAC, in addition to the county and school district lines.
- The appraisal protest deadline for the applicable district, which is not uniform across Bexar, Comal, and Kendall.
- Whether any homestead cap from the seller will reset at your purchase price, changing the taxable value in year one.
None of these are exotic requests. They are simply not automatic in a market where the standard closing checklist assumes one county per city.
A quirk that only matters if you sell later
There is one more line item that shows up rarely but is worth knowing. The Fair Oaks Ranch Municipal Development District, which collects a local sales tax that supports city projects, does not cover the entire city. The district's boundaries include the portion of the city in Bexar County and the Fair Oaks Ranch extraterritorial jurisdiction area in Bexar county where San Antonio MTA sales and use tax is collected, and the Fair Oaks Ranch extraterritorial jurisdiction area in Kendall County, and the district excludes any portion of the city or its extraterritorial jurisdiction in Comal County.
That has no direct effect on your homestead tax bill. It does affect how the city funds amenities on your side of town over the long horizon, which is worth understanding if you are buying with a fifteen- or twenty-year hold in mind.
FAQ
If I live in Kendall County, why is the city tax bill coming from Bexar County?
The City contracts that service out. Bexar County collects the money and forwards it to Fair Oaks Ranch. A couple of years ago, the Kendall County Appraisal District, which had historically collected city property taxes regardless of which county you live in, decided they no longer wanted to provide this service, which caused the city to find a new service provider, the Bexar County Tax Assessor-Collector office.
Can I protest my appraisal with the City?
No. The Tax Appraisal Office in the county where your home or property is located sets your appraised value, and the City has no role in this. Protests go to Bexar, Comal, or Kendall depending on where the parcel sits.
Are HOA dues and country club membership the same thing here?
They are not. The master association and the Fair Oaks Ranch Golf & Country Club maintain separate dues structures, and buyers should budget for them independently rather than assume one includes the other.
When are tax bills mailed?
City tax statements go out in October, and county and school district bills follow in November. All become delinquent on February 1 of the following year.
The tax mechanic in Fair Oaks Ranch is not a warning against buying here. It is a reason to work with a team that has closed transactions on all three sides of the map and knows which questions to ask before the appraisal notice arrives.
