I was under the impression that Washington property tax rates were higher than Oregon's. True or false?
Braumeister,
Unfortunately, your question does not have an absolute answer largely because property taxes are locally driven both in terms of rates and quality of administration. You really do need to make community to community comparison for a home of a given value. My original comment was based largely on living here in Wash State and the many comments from my Oregon friends.
Here is where you can get some facts about Oregon:
http://www.oregon.gov/dor/STATS/docs/303-405-12/property-tax-stats_303-405_2011-12.pdf
This resource will tell you rates for each county as a ratio of rates per $1000 of RMV (real market value). Eugene is in Lane Co and the rate is 10.67/1000 RMV. In Oregon the range is from 6.45/1000 to 13.54/1000.
The area around Portland being in the top tier. So as you can see almost a 100% difference in Oregon and that is before you try to account for different quality of administration between counties. Metropolitan counties will have the strongest and most "aggressive" assessors who will stay on top of valuations, especially in a rising market. More rural counties, much less so and often have no interest in pushing the valuation until forced by their respective state's Dept of Revenue.
I lived in the Puget Sound area (King Co) for 26 years and can tell you that the Assessor was amoung the most aggressive in the state. Why does this matter--he would "reassess" annually. In contrast, I now live at the Eastern edge of the state, and the assessor has not changed values on our home in the 7 years we have lived here. I have bought rental property in the area and found I can call the assessor and have the value changed to reflect our purchase price immediately (usually at a discount to about 90% of purchase). In King Co, you would have had to file a protest of your assessment and have the Board of Equalization reduce your value--does not happen often and only for the most serious situations-eg major damages or structural change in neighborhood.
One other difference between Oregon and WA true statewide--Oregon caps annual increases in total property tax at 103% while WA is 101%--note this is total property tax revenue and NOT for an individual tract.
You might find this conversation from a City-Data Forum of interest:
Real Estate Taxes (Seattle, Olympia, Port Townsend: sales, real estate market, rental) - City-Data Forum
To get a firmer handle on specifics, I suggest you find similar properties in communities that would interest you in WA & Oregon and then check the actual taxes being paid. Info is all public and often will show in Trulia and Zillow.
Hope that helps you a bit.
