Suing you for what?

You don't sound like bad tenants. Your landlord sounds like a loon - I had one of those once. He served me with an eviction notice the day I was moving out of my apartment and into my house, and told me he could have me evicted from the house I bought because I moved before he gave me permission.

No kidding.

If you're packing, I presume you've found a new place and are in the process of getting out of this one?
