Don't hassle the LL clause in lease?

[Alan Bosca]

Hi -

Has anyone ever put language to the effect of "if tenant threatens legal action against landlord or causes landlord to have to seek an attorney's advice, this agreement can be terminated as LL's discretion."  My concern is that I've had tenants who seem great at the outset and total nightmare, constant threats about every little thing after a month or two.  Often due to unforeseen personal issues they have, not actual property condition issues.  

So, of course, one can screen as well as possible, but in the event you get a Jeckyl/Hyde, it would be nice to have language to opt out.  

Month to month doesn't really work for me, I'm talking about a year min lease.

Thx for any input!
