I have a lease with them, but I rented to them almost 3 years ago, so I understand that they are now in a month-to-mounth position. They owe over 18 months rent. Originally the rent was 1600/mo. In April I told them that they could pay $1200 per month. Since then they still have not paid the full month's rent, only partial payments. I have found out that the husband is on drugs and it is suspected that he is dealing with stolen property from the premises. The neighbors see him leaving late at night and comming in at 2 or 3am with a trailer load of stuff and putting it in my shop building. He told me that he gets free stuff from abandon storage lockers. If that were the case he wouldn't be picking it up at 3 am. He went to jail 5 yrs ago for stealing, I think he doing it again.Can I give him 3-day notice or does it have to be 20?
