NJ Month to Month Lease Termination

[Mike Savage]

Happy new year everyone. 

Is it easy enough to terminate a month to month lease in 1 of the units in 3 family house that is not owner occupied?
Location : Weehawken, NJ. 

Issues: has been difficult with this tenant forever. tenant is not paying increased rent from the last 2 months even after increased rent letter sent by normal and signed mail, is ignoring texts & phone calls apart from other issues like having pet in non pet unit, parking bike in side alley etc.  

If so, can I do it on my own or need a lawyer for it?
Do I need to provide all the reasons in the letter?

Thanks.. Mike
