in Oregon the public cannot bid on tax sales they escheat to the state and then are sold as surplus.. but its so rare to have anything go in that state.CA will have a lot but 99.9% of the parcels that go are bare land.. with the majority of it pretty worthless strips or unbuildable lots.Wa you can buy at tax sale but again very few real parcels of value go and virtually no improved properties..In your area..
