How to Search Miami County Property Records

Start at the Auditor's website and use the property search page. Type in an owner name, street address, or parcel ID. Results come up fast. Each record shows the owner, property address, legal description, land use code, and current values. You can also check building details like square footage, room count, year built, and construction type. Sales history shows past transfer dates and prices going back several years.

The GIS map system gives you a visual way to find Miami County parcels. Zoom into a specific area and click on any lot to see its information. The map shows property lines over aerial photos. These are approximate boundaries for tax purposes. They are not surveys. If you need exact lines, hire a licensed surveyor.

For recorded documents like deeds and mortgages, check the Recorder's search system. Look up records by grantor name, grantee name, document number, or recording date. Under ORC Section 149.43, all Miami County property records are public and free to view during business hours.

When land changes hands in Miami County, the new deed must be recorded here. That recording gives public notice of the transfer.

Miami County Property Tax Records

Property taxes in Miami County fund local schools, police, fire, roads, and government services. Tax bills are calculated by applying local mill rates to each parcel's assessed value. One mill is $1 of tax per $1,000 of assessed value. The Ohio Property Tax Rate Database lists current rates for all taxing districts in Miami County including townships, school districts, and special levies.

A full reappraisal occurs every six years with a triennial update at the midpoint. The Ohio Department of Taxation certifies value changes based on sales ratio studies. Property owners who believe their valuation is wrong can file a complaint with the Board of Revision. The filing deadline is the end of March for the prior tax year.

Apply at the Miami County Auditor's Office by December 31st of the year you want coverage to start. Sign the form under penalty of perjury.
