This is an illustrative, hypothetical example, not a report of one specific verified customer transaction. It walks through realistic Multnomah County numbers: a home assessed at $1,052,250 against comparable sales showing a market value of $738,038 -- a $314,212 overassessment worth $5,648 per year in excess taxes. Here is how that kind of case gets built and what it means for Portland homeowners dealing with Measure 50 and Oregon's unique assessment system.
| County Assessed Value | $1,052,250 |
| Market Value (from comps) | $738,038 |
| Overassessment | $314,212 (29.9%) |
| Effective Tax Rate | 1.80% |
| Potential Annual Savings | $5,648 |
| 10-Year Savings | $56,480 |
Portland's SW hills neighborhood sits above downtown with views, mature trees, and home values that have swung dramatically over the past few years. During the pandemic-era boom, prices in this area surged past $1 million for properties that previously traded in the $700K-$800K range.
The market has since corrected in this scenario. But the county's assessment has not.
Picture a homeowner whose assessment notice arrives showing $1,052,250, while homes selling nearby are going for significantly less. The question is whether the data backs up that instinct.
In this scenario, it does -- by $314,212.
Oregon has one of the more unusual property tax systems in the country, thanks to Measure 50 (passed in 1997). Here is how it works:
In this case, the RMV of $1,052,250 was the controlling value. If it were corrected to $738,038, the tax savings would be immediate and substantial.

Portland's SW hills present a challenge for comparable sales analysis: the homes vary widely in size, lot, view, and condition. Finding true comparables requires careful matching.
Three strong comparable sales were identified, all meeting the core criteria:
The median sale price of these comparables came in at $738,038 -- roughly 70 cents on the dollar compared to what the county claimed the property was worth.
Three comps may sound like a small sample, but in a neighborhood where homes are highly individual, three well-matched sales carry more weight than fifteen loosely matched ones from miles away. Quality over quantity is what review boards look for.
Several factors contributed to this $314,212 gap:
Oregon's appeal process runs through the county Property Value Appeals Board (PVAB, formerly BOPTA):
The key is presenting a clear, evidence-based case. PVAB members see hundreds of petitions. A well-organized packet with relevant comparable sales, adjusted for differences, stands out immediately.
At nearly $500 per month in excess taxes, the financial impact is significant:
For a $49 evidence packet, the return on investment is 115x in the first year. Even a partial reduction -- say the board meets halfway and lowers the value by $157,000 -- still yields $2,824 in annual savings.
In this illustrative scenario, a Portland homeowner is paying taxes based on a $1,052,250 valuation when comparable homes in the same neighborhood are selling for $738,038. The 29.9% overassessment translates to $5,648 in excess taxes every year -- $56,480 over a decade.
Gaps like this show up in real market data. When the county's number is wrong, it just takes someone to compile the evidence and present it.
