From the standpoint of an IRS lien then yes I would say you are in the clear, you do not have to worry about a redemption, (in which you would be paid whatever you paid for the home plus interest by the IRS if you didn’t want to cure the lien).
As far as the property taxes then yeah just go and pay them and you will be fine. Check out the recordings on the home at the assessors office as well, that is a wise step… and free also.
