How soon to evict current tenant

[Shawn M.]

I am buying a property to renovate but it is coming with an existing tenant on a month to month lease that I need to get out as soon as possible. Since I do not own it yet I do not think there is much I can do yet and I have to wait until I close.

With that being said, the day close I am going to give them a '30 day to vacate' letter stating that I am not renewing the lease and to please move out.

My question is should I be a pr*ck and back it up with an eviction letter? just in case they do not move out in 30 days i'll have the process started. or should i give them the benefit of the doubt and no piss them off and hope they move out in the 30 days?

Has anyone gone through this before? I could also do a cash for keys to be out in 30 days.

Any good strategies?
