Property tax delinquent Property

[Daniel Fierros]

Hello BP (Sry about the sideways profile pic, I've honestly tried to fix that to no avail) I have an elderly couple who is motivated to sell their home because they are behind $23k on their property taxes in the Greater Third Ward area in Houston TX 77004.  If I were to buy their property from them, is there any way I can reach a settlement with the county on the amount of delinquent taxes owed?  Has anyone had experience negociating or coming to an agreement with the county?  Public records say that the it's under suit.  All replies are much appreciated.  Thank you
