About the Gresham Property Market
Gresham is a city located in Multnomah County, Oregon. Every property inside the Gresham city limits is assessed by Multnomah County Assessment & Taxation, which applies Oregon property tax rules uniformly across the county.
Because Gresham property values are set at the county level, the $450,000 county median home value and 1.12% effective tax rate apply to homes throughout the city. Homeowners who believe their Gresham home is over-assessed have the right to file a appeal directly with Multnomah County Assessment & Taxation before the December 31 deadline.
Oregon allows the assessor to defend or adjust the assessed value during a appeal, so Gresham homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Gresham Property Market Context
As a city in Oregon, Gresham inherits the state's assessment framework — which shapes how over-valuations occur and how homeowners can fight them.
Oregon market character
Oregon uses a permanent rate system (Measure 50) that caps annual assessed value increases at 3%. Assessed value is usually well below real market value, but if real market value drops below assessed value, homeowners can petition for relief.
How Oregon handles appeals
Oregon homeowners file a petition with the county Board of Property Tax Appeals (BOPTA), then the Magistrate Division of the Oregon Tax Court. The state is procedurally friendly and evidence-driven.
When to file in Gresham
BOPTA petitions are due by December 31 of the year the tax statement is received. This is one of the latest deadlines in the country.
