How does the Bexar Central Appraisal District determine my upcoming proposed market value for property taxes in Oak Hollow Park?
The Bexar Central Appraisal District (BCAD) determines the upcoming proposed market value of your home using a method known as mass appraisal. Rather than sending an individual appraiser to inspect each of the 295 homes in Oak Hollow Park, BCAD uses statistical modeling and a Computer Assisted Mass Appraisal (CAMA) system to value entire groups of similar properties simultaneously.
The automated calculation process follows specific criteria to decide your home’s proposed value:
- The Neighborhood Code Assignment
BCAD groups properties into specific geographic and statistical boundaries using a unique neighborhood code. All 295 homes within Oak Hollow Park are linked under a shared profile. This tells the system that these properties share the same location premium, general economic trends, school district boundaries, and localized market environment.
- Standardized Property Characteristics
The CAMA system tracks data points specific to your individual property structure. To determine your baseline footprint, the mass appraisal formula applies fixed cost schedules to attributes such as:
- Total Living Square Footage and lot size.
- Age of the Structure (which calculates standard depreciation).
- Construction Quality and Class (e.g., brick vs. siding, roof style).
- Permitted Improvements reported via city records, such as added decks, patios, or pools.
- The Sales Comparison Approach (Market Data)
Texas law mandates that property be appraised at 100% of its fair market value as of January 1 of each tax year. To satisfy this, BCAD applies a computerized sales comparison approach:
- Gathering Area Sales: The system evaluates recorded real estate transactions (sold homes) within your specific neighborhood code over the preceding calendar year.
- Mathematical Adjustments: The software selects recently sold homes (comparable sales or “comps”) and applies automated formulas to align them with your property’s specific dimensions.
For example, if a sold home down the street is slightly larger or newer than yours, the algorithm mathematically adjusts that sales price downward to estimate what your specific home would have sold for under prevailing market conditions.
Where Mass Appraisal Can Miss the Mark
Because this process relies heavily on an automated system, it only evaluates properties from the outside. The algorithm assumes every home in Oak Hollow Park is in average condition for its age and type. It cannot automatically account for internal realities like dated interiors, hidden foundation issues, major deferred maintenance, or unique property damage.
* If your specific home has localized layout disadvantages or repair needs that a mass system overlooks, filing an official protest before the annual deadline allows you to present individualized evidence to correct that valuation.
If I protested my property taxes and got a reduction based on no improvements and still having deferred maintenance, would the Appraisal District remember the following year?
The short answer is no, you will not automatically get the same reduction the following year, and you will most likely need to protest again.
In Texas, property tax valuations reset every single calendar year based on the market conditions
on January 1. Because your previous reduction was based on temporary or subjective factors—rather than a structural permanent change—the automated mass appraisal system will likely overwrite your hard-earned discount when the new notices go out.
Here is why your reduction doesn’t carry over automatically, and what you should know:
- The Computer Doesn’t Remember Your Maintenance Issues
The Bexar Central Appraisal District (BCAD) uses automated software to value your neighborhood. When the next appraisal cycle begins, the computer algorithm completely resets your home to “average condition” for its age and size. It does not automatically carry over deductions for uncompleted repairs, cracked tile, or a failing roof from the previous year’s protest.
What You Must Do the Following Year
To maintain your tax savings, treat the upcoming tax season as a fresh start:
- File the Protest: File your notice of protest before the deadline (typically May 15) to preserve your rights and freeze any automatic increases.
- Get new contractor estimates: If you still haven’t fixed the deferred maintenance, take fresh, time-stamped photos of the issues to prove they still exist.

Title: The “Amnesia” Trap: Why Last Year’s Property Tax Win Won’t Save You This Year
For our Oak Hollow Park homeowners who successfully protested last year;
- The Big Misconception: “I proved my house needed a new roof last year and got my value lowered. I’m safe for this upcoming year, right?”
- The Cold Reality: In Texas, property tax valuations completely reset every single year on January 1.
Why the System “Forgets” Your Reduction
- The Mass Appraisal Reset: The Bexar Central Appraisal District (BCAD) uses computers, not human eyes, to value homes. Every spring, the computer wipes the slate clean. It automatically assumes your home has been repaired and is back to “average condition.”
- No Automatic Carryover: Deductions for deferred maintenance, dated interiors, or foundation cracks never automatically roll over to the next year.
