This guide is a working reference to ad valorem property taxation, assessment appeals, exemptions, and the delinquency process that can cost an owner the property. It begins with how a bill is computed and how mass appraisal produces the value that drives it, then sets out the two independent grounds for appeal and the evidence that establishes each. Valuation chapters cover the sales, income, and cost approaches, adjustment methodology, sales ratio analysis, and the valuation date. Exemption chapters catalogue homestead, senior, disability, veteran, agricultural, and hardship programs, including retroactive claims. Procedural chapters follow the informal review, the local board, the state tribunal, and judicial review, noting the federal jurisdictional bar. Delinquency chapters set out liens, lien sales, redemption, and tax deeds, with the constitutional notice and surplus proceeds decisions that decide these cases. Further chapters address mortgage escrow effects, commercial and income property, tangled title, and discriminatory assessment patterns. Reference tables and practice pointers close the guide, with all authorities linked to their text.
