Why Olmos Park Homeowners Are Overpaying
Olmos Park’s city rate of $0.5114 per $100 is 38% higher than Alamo Heights and 43% higher than Terrell Hills. That means every dollar of BCAD overassessment costs Olmos Park homeowners more than their neighbors in the adjacent enclaves. On a median home assessed at $928K, even a small valuation error translates into hundreds of extra dollars per year.
The protest case here is exceptionally strong. Architect-designed, one-of-a-kind homes from the 1920s–1950s — by luminaries like H.H. Hugman, O’Neil Ford, and George Louis Walling — are among the most difficult properties in all of Bexar County for BCAD to value accurately. A 1928 H.H. Hugman Spanish Revival cannot be compared to a 1955 ranch, yet BCAD’s mass appraisal model tries.
Teardown-rebuild distortion is severe. Developers pay $900K for a lot, demolish a historic home, and build a $2.5M new build. Every surrounding owner’s assessment rises. Olmos Park lacks an architectural review board, meaning demolitions face no public review and the pace of teardowns is accelerating.
- Highest enclave tax rate ($2.21/$100) makes every overassessment dollar more costly
- Architect-designed one-of-a-kind homes are impossible to mass-appraise accurately
- Severe teardown-rebuild distortion with no architectural review board oversight
- Foundation issues are endemic in homes built before 1940 on stone and concrete foundations
- Only a $10,000 over-65 city exemption (saving roughly $51/year) and no general city homestead exemption
The 2025–2026 Reappraisal Reprieve
BCAD adopted a biennial reappraisal plan: market values settled through protest in 2025 carry forward unchanged to 2026 unless new construction or clear-and-convincing evidence warrants a change. A successful protest now could lock in lower values for two full tax years.
How We Build Your Olmos Park Case
Olmos Park’s unique housing stock demands a protest strategy built around the specific failures of mass appraisal in this enclave.
Unequal Appraisal Analysis
The #1 strategy — showing similar-era Olmos Park homes assessed at wildly different rates per square foot. Mass appraisal creates systematic inequities in small, architecturally diverse communities.
New-Build Exclusion
We exclude new-construction transactions from comparable sales. A $2.5M teardown-rebuild is not a valid comp for your 1930s Spanish Revival.
Age-Related Depreciation
Homes 80–100 years old warrant significant depreciation adjustments for foundations, original systems, and structural wear that BCAD does not account for.
Condition Documentation
We document foundation cracks, original-era plumbing and electrical, and needed repairs with photo evidence that provides powerful visual support at hearings.
What It Costs in Olmos Park
On a median Olmos Park home assessed at $927,529 with the highest enclave rate of approximately $2.212 per $100, the estimated annual tax bill is roughly $20,517. A conservative 10% reduction in assessed value would save approximately $2,052 per year. Our fee: 40% of that first-year savings, or about $821. With the reappraisal reprieve carrying the reduction into 2026, your net benefit over two years could reach $3,283.
No upfront cost. No minimum fee. No auto-renewal. You only pay 40% of first-year savings. Year 2 and beyond, you keep 100%. See the 5-year math →
Frequently Asked Questions
Can my taxes go up if I protest?+
No. Texas Tax Code §41.43 prohibits the appraisal district from raising your assessed value as a result of a protest. The worst outcome is your value stays the same. There is zero risk to filing.
Why is the Olmos Park tax rate higher than Alamo Heights?+
Olmos Park’s city rate is $0.5114 per $100 compared to Alamo Heights’ $0.3701 and Terrell Hills’ $0.3580. All three share the same school district (AHISD at $0.9572), so the difference is entirely at the city level. The higher rate reflects Olmos Park’s independent police, fire department, and municipal services for a smaller tax base.
How does BCAD handle architect-designed homes?+
It doesn’t, effectively. BCAD’s mass appraisal models use statistical averaging, which works reasonably for tract homes but fails completely for one-of-a-kind architect-designed residences. Each Olmos Park home needs individual assessment — exactly what 77 appraisers for 774,100 parcels cannot provide.
What is the filing deadline?+
May 15, 2026 (or 30 days after BCAD mails your Notice of Appraised Value, whichever is later). Filing can be done online, by mail, or in person.
Does ATD handle the entire process?+
Yes. We handle all four stages: informal hearing, ARB hearing, binding arbitration, and district court. We file the protest, build the evidence package, attend all hearings, and negotiate on your behalf.
Are there any Olmos Park exemptions I should know about?+
Olmos Park offers only a $10,000 over-65 city exemption, which saves roughly $51 per year at the city rate. There is no general city homestead exemption. Your biggest savings opportunity by far is protesting the assessed value, not exemptions at the city level. School district exemptions ($140,000 homestead) still apply.
