Tax deed sale percentage buy down in Utah
I'm interested in bidding at a tax sale in Utah county. We are a tax deed state. The county recently changed the bidding process from a typical bid up auction to a percentage bid down auction. How they do it is they start the bidding at 100% of the property for the cost of the back taxes. To compete you bid smaller percentages like 95%, 90% ownership ect. The remaining percentage of the ownership is the original owner. Having two owners on the property is messy and complicated but I've researched what to do there. My question is do the liens on the property that normally disappear in a tax deed sale still disappear if the original owner retains some percentage of the property?
