Impound Accounts and tax delinquency

[Neal Collins]

I am looking at the tax delinquency list in a county in Oregon and wondering if a person is delinquent more than a year or two, can it be inferred that they own the place free and clear? If they didn't wouldn't the impound account on the mortgage pay the taxes on time (assuming it's not a private lender)? Any guidance on this would be much obliged.
