What CMi does

CMi (Cantrell McCulloch, Inc.) is a privately held Texas professional corporation founded in 2001 that provides ad valorem (property) tax consulting services to commercial real estate owners and business personal property owners. The firm operates two core service lines: Real Estate Property Tax Consulting — covering multifamily housing, office, retail, industrial, hotel, and vacant land properties through strategic planning, research, case preparation, expert witness testimony, and litigation support across the entire appeal process; and Business Personal Property (BPP) Tax Consulting — covering equipment appraisals, inventory valuation, renditions, and audits for assets ranging from startups to Fortune 500 businesses.

Underpinning service delivery is a proprietary technology stack anchored by the PTS Tax Software System, which maintains property data files on more than 9,000 tax parcels nationwide, supplemented by a deep database of comparison figures used in BPP reduction consulting. CMI also operates an online client portal for account management. The firm runs a relationship-based, sales-led go-to-market model led by founding partners Mark J. Cantrell and Robert A. (Bobby) McCulloch, supported by ~15 senior vice presidents and vice presidents bearing professional designations (MAI, ASA, CCIM, CPA, CMI).

CMi generates revenue through professional service fees on a quote-based, engagement-by-engagement basis, with a customer base that includes AT&T, Verizon, McWane, Wilsonart, Bain Capital, Carlyle Group, and Baylor University, among 30+ named enterprise clients. The firm is the second-largest property tax consulting group in Texas and operates in 29 states through its affiliation with the National Property Tax Group, representing over $52.5 billion in commercial property assessments and delivering more than $135 million in client tax savings in 2023. Growth has been entirely organic with no external funding or institutional ownership.
