Make sure it explicitly explains the process for termination if you are unhappy with their services, especially if they violate the terms of your agreement.3.

(look up my detailed posts on the benefits of MTM here on BP)  How about getting a plumber to triage the leak, serve them a notice of termination (or not renew their term), and then you kill two birds with one proverbial stone? 

Currently you can terminate your lease on a SFH for any reason you want.  

In that case, if they can provide us with proof of contract cancelation, we terminate their lease without a fee and refund their full deposit (assuming there isn't any property damage).

He can terminate if he likes and you can let him out without damages might be best for both of you.

I also recommend you start figuring out how to terminate a lease when the tenant is consistently late, or how to evict if they fail to pay by a certain date.

I would check out the long term strategy as well (But have a clause that you can terminate the lease if you sell the house). 

Need an advice.My tenant has a lease till the end of 2024.He wanted to terminate and since the end of May we agreed he will pay 3 months for termination, which he did.

Do you have grounds to terminate PM and change? 

Yes, you can terminate a lease based on their violations.
