[Donta' Collins]

Hello all, While investigating a couple of property that have tax liens I noticed a unoccupied house that was in awesome condition. The house does not have a tax lien on it. There was a notice the door.  The notice stated " This property has been determined to be vacant/ abandoned. This has been reported to the mortgage servicer. This property may have its locks replaced and/or plumbing system winterized. Do anyone know how can I purchase it. I know the house was built in 1998 and have an appraisal value of $70,000.
