How do I find out if back taxes are owed on property

Call the county assessors office but you may need to know the tax ID # not just the address. Is this your property?

In many areas, you merely look it up on the property tax office web site, Where I live you see who owns it, what they paid for it, and what the taxes are and if any taxes are due.

I have to ask, why do you care, is it a home you rent that you are afraid is going to be sold ?

You can not just go pay back taxes and own a property, if that is what you were thinking
