Yes, this is only legal way

Cash for key is another way, but I would not do that to spoil the tenant.  Eviction is hard for you, but also hard on the tenant who has good/ok credit score.  The consequence is much hard for tenant than your loss.

Rental is a business, do your calculation based on the trade-offs.  But you should budget the eviction in your business, or the cash for key (I do not like it in your case).
