There are times when a property owner is unable to pay the obligation in property tax. When this happen, a property owner becomes a delinquent taxpayer and a governing authority is in charge of collecting the taxes. However, if the authority is not able to collect the required property taxes, they will opt to take the final step to collect the taxes. The public tax lien auction is the final step that will take the delinquent properties to be sold. Tax lien auction is an auction ordered by the court depending on the nature of sales in the form of tax lien certificates or tax deed sales.
