What Makes PropTaxLab Different

We built PropTaxLab because we were tired of Houston homeowners overpaying — both on taxes AND on protest firm fees.

Full Evidence Transparency

Most firms file your protest and never show you what they submitted. We give you the complete evidence package — equity comps, cost-to-cure, adjusted analysis, market data. You see exactly what HCAD sees.

Cost-to-Cure Analysis (USPAP)

Old HVAC, dated kitchen, foundation issues? Most firms skip these deductions entirely. We estimate repair costs using USPAP-standard methodology and deduct them from your value — often adding $20K-$80K in extra reductions.

Houston-Only Focus

We don't spread across 7 states like OwnWell or across all of Texas like O'Connor. We know HCAD's data, their neighborhood codes, their patterns, and their hearing history inside and out.

Founder Reviews Every Report

At volume firms, your case is one of 50,000. At PropTaxLab, the founder personally reviews every evidence package before delivery. That's why our reports include analyses others don't even attempt.

DIY Option — Keep All Your Savings

No other firm gives you a professional evidence package for a flat fee. Our $199 iSettle Pack includes everything you need to file yourself — pre-written comments, step-by-step screenshots, and evidence formatted for HCAD submission.

Neighborhood Hearing Intelligence

We analyze HCAD's own ARB hearing results for your specific neighborhood — showing historical reduction patterns that prove systematic over-assessment. No other firm includes this data.
