If the lease has expired, provide the proper notice for the rental increase or termination...and she can choose. 

I would give them a choice: pay the animal violation fee ($200 upon discovery, $50 per day until the animal is removed) and remove the animal forever, or terminate their lease within 14 days, refund their deposit, and find a new tenant that follows my rules.

Hello, quick question about terminating/not renewing the month-to-month lease.In GA, the landlords are required to give 60-day notice, but our lease agreement (attached below) states that "either party can give 30 day notice."

2) What happens if one of the partners wants to terminate the business relationship and wants their investment out now?

And if things don't go well are JVs easy to just terminate?

Your Property Management Agreement should spell out how to terminate and if there are any penalties for early termination.

If your sales contract has a "time is of the essence" clause or other language allowing you to terminate it if the buyer misses their contractually obligated dates then I would do that and just let your listing contract expire in 2 weeks.

If they fail to respond with an option, we automatically send them notice of termination and expect them to be out by 11:59PM on the final day.

Mind you no termination has been signed.

When they refused, you could have terminated their lease.
