Sexual Offender

We lost a sale yesterday as the potential buyer looked up our address on the Sexual Offender website and found we have one in the park. We have known about this guy since he moved in but that was probably around 2000. We would never let another one in if we can help it.( We believe if we can run criminal on new home owners we can find out if they are a sexual offender). it was reported that he just got out of jail for the same thing again. Our manager talked with the wife and made an appointment to talk with him on Monday to see why he was in jail this time or if he was in jail. We believe we can evict him but not sure since we let it go for so long. What’s your thoughts and experience with this subject?
