This page helps users complete a property search in Montgomery County, Ohio and understand which official tools can be used for address, owner, parcel, tax, GIS, and related real estate information.

The Montgomery County Real Estate Tax Information site is the main public search resource for real and personal property assessment and tax record information. The Montgomery County Auditor’s Office also provides real estate, GIS, deed transfer, homestead, rental registration, and value appeal information.

For a property search by location, use the Montgomery County Address Search. The search page lets users enter an address number when available and a street name without adding the street direction or suffix.

  • Address number, if known
  • Street name without direction or suffix
  • Optional filters, sorting, and results-per-page settings

Use broad terms when needed. The address search allows an asterisk as a wildcard, and a street name alone can return addresses on that street or addresses beginning with that street name.

  • Enter the street name in the search field.
  • Add the street number only if it helps narrow the results.
  • Leave off terms such as street direction or suffix.
  • Use the search results to select the matching property record.

Search hint: If the system is unavailable due to maintenance, check again later rather than assuming the record is missing.

Other real estate search options

The Montgomery County Real Estate Tax Information site provides read-only access to real and personal property assessment and tax record information. Users can start with the available search types, including address, owner, parcel, and advanced search options.

The county’s Real Estate page also points users to property search resources and related Auditor services, including property value updates, Board of Revision appeals, deed transfer, homestead, rental registration, tax reduction programs, and GIS.

The Montgomery County Treasurer’s Real Estate Tax Information System supports searches for tax records by parcel, owner, or property address. It also lets users select a tax year before searching.

  • Parcel ID, such as A01 00107 0001
  • Owner name in last-name first-name format
  • Property address with street number and street name
  • Tax year selected from the available options

Complete only one search field for best results. When results appear, select the Parcel ID to view the record.

Users who need tax-focused records can use the Treasurer real estate tax search.

GIS and parcel mapping

The Montgomery County Auditor’s GIS resources help users view parcel mapping information. The GIS page directs users to the interactive Auditor parcel map and notes that the county does not guarantee that GIS data is free from errors or inaccuracies.

For map-based property research, use the Montgomery County GIS page or the Auditor interactive GIS map.

Property owners who disagree with a property value can use the Montgomery County Board of Revision process. The Board of Revision filing period is January 1 to March 31, and the board can make changes to property values, not tax rates or tax amounts due.

Related Auditor services include deed transfer, homestead exemption, and rental registration. Deed transfer information includes a conveyance or transfer fee of $3 per $1,000 of the actual sale price and $0.50 for each parcel transferred.
