When you submit the funds to the state for a tax lien certificate or tax deed and receive the document what are the steps that need to be taken for the investor to keep the future taxes on the property paid?

Some information I have read seems to lead that there can be multiple tax liens on properties. Does the investor notify or record the document in the county the property is located in? Basically, how does the tax lien holder (investor) pay the future due taxes until the property is redeemed or the title is quieted?

The investor assesses the  property in his own name and pays the taxes as they come due each year.

The only place that has multiple tax liens and multiple tax sales for the same property and the same year is Selma. There is NO guidance in the law, or by asking local attorneys or officials, about what happens if one person has the Selma tax sale certificate and a different person has the Dallas County tax sale certificate.  My take-away:  Don't invest in Selma tax liens unless you are REALLY confident you know who will will in a lien fight and/or you buy both liens.
