Article II Section 28 of the Tennessee Constitution states: "…all property real, personal or mixed shall be subject to taxation…" Your property tax dollars are used by city, county, and state governments to provide funding for roads, parks, fire and police protection, public schools, and many other local services. "Market Value" is defined as the most probable price, as of a specified date, in cash, or in terms equivalent to cash, or in other precisely revealed terms for which the specified property rights should sell after reasonable exposure in a competitive market under all conditions requisite to a fair sale, with the buyer and seller each acting prudently, knowledgeably, and for self-interest, and assuming that neither is under undue duress.
