@Joshua Hively your question doesn't make a lot of sense. Corelogic is the company that offers the Listsource produce. The tax bill mailing address goes to the owner of the property. If they are listed, then they are likely the owner, or perhaps acting as agent for the owner.
Bank owned properties? Corelogic does offer tax services - https://www.corelogic.com/solutions/property-tax-services.aspx
