Property Value Estimator

This estimator takes a property value you provide and works it through the value chain of the state you choose — assessment ratio, exemptions, taxable value — and, if you supply the tax rate from your own bill, an estimated annual property tax.

It is an educational calculation, not an appraisal and not an automated valuation model: the tool does not estimate what a property is worth. Each state’s edition uses that state’s own verified rules, because assessment systems differ far more than they resemble each other.

Choose your state

Seven states are supported, each with rules verified from official sources. A state without an edition does not yet have enough verified numeric data — the site does not publish a generic page pretending otherwise.

• Texas Property Value Estimator — See how a Texas property's appraised value becomes a taxable value, and estimate the property tax that follows — using the homestead exemption rules verified from the Texas Comptroller.
• Florida Property Value Estimator — See how a Florida property's just value becomes a taxable value — with the two-tier homestead exemption computed exactly — and estimate the property tax that follows.
• Ohio Property Value Estimator — See how an Ohio property's true value becomes the taxable value the levies are applied to — the fixed 35% ratio computed exactly — and estimate the property tax that follows.
• Georgia Property Value Estimator — See how a Georgia property's fair market value becomes its assessed value at the 40% ratio, apply the state standard homestead exemption, and estimate the property tax that follows.
• Arizona Property Value Estimator — Arizona taxes the limited property value at a 10% assessment ratio — not the full cash value. Enter the values from your notice of valuation and estimate the property tax that follows.
• Nevada Property Value Estimator — Nevada taxes 35% of the assessor's taxable value. Enter the taxable value from your assessor's record and estimate the property tax that follows — with the tax-cap abatement explained where it applies.
• Michigan Property Value Estimator — Michigan assesses at 50% of true cash value and taxes taxable value. See how the two figures relate, when a transfer of ownership uncaps the taxable value, and estimate the tax that follows.

What this tool can and cannot do

• Can: compute assessment ratios, exemption amounts and taxable values from verified state rules, and estimate a tax at the rate you supply.
• Cannot: value your property, verify your inputs against official records, model every local exemption or special assessment, or replace your tax bill.

Where the state rules come from

Every ratio, exemption amount and cap mechanic in the calculators is cited to the official source it was verified from — statute text, departments of revenue, or county officials. See our methodology and the evidence and sources page. For the rules that limit how fast values can rise, use the assessment checker (Texas and Florida).
