What Ad Valorem Advisors does

Ad Valorem Advisors (AVA) is a Texas-based property tax advisory firm founded in 1999 that specializes exclusively in serving homebuilders and land developers. The firm operates from two offices — Katy (greater Houston) and McKinney (Dallas/Fort Worth) — and serves clients across Houston, Dallas/Fort Worth, San Antonio, and Austin metropolitan areas, covering 50+ Texas counties. Its service portfolio includes property tax appeals, consulting on budgeting and valuation, agricultural exemptions, rollback taxes, business personal property filings, MUD/PID account management, and ownership corrections. The firm manages 70,000+ accounts for 45+ builder and developer clients.

The firm's core differentiator is its proprietary TaxPro client portal, which provides a centralized dashboard for tracking assets under management, property values, appeal statuses, tax payments, and savings, supplemented by a searchable Value Estimates tool for closing prorations. The underlying technology is positioned as a custom-built platform leveraging live value estimates integrated with the firm's protest and consulting workflow. Distribution is entirely direct — sales-led via two Texas offices — with no channel partners, resellers, or external sales infrastructure. The team of approximately seven named professionals includes President Toby Ware (former Deloitte valuation/appraisal), Vice President Brad Colliander (formerly of Metrostudy, John Burns Real Estate Consulting, and Ryland Homes), and several consultants who previously held finance roles at national homebuilders including Pulte Homes, Toll Brothers, Taylor Morrison, and History Maker Homes.

The business model is professional services: custom, quote-based consulting engagements on multi-year contracts with homebuilder and developer clients. Pricing is not publicly disclosed. No external funding, no M&A activity, and no parent company involvement is evidenced; the firm appears to be founder/management-owned (Toby Ware is described as owner and operator) and has grown organically over 25+ years. Marketing is constrained to the company website (avatx.com), direct outreach, and the client portal for retention.
