I would like to check the rental history on a property that I'm looking at. I'm in Oregon if that makes a differcence.

What does the currant owner say? How are vacancy rates in your area?

Ask to see his schedule E from his federal tax returns for as far back as you can get. While not foolproof, this will at least let you see what he is reporting in terms of income and expense, and hence occupancy.
