Terminating Month to Month

[Mark Bookhagen]

Hi BP,

I'm looking for some advice. I think I should terminate a m2m lease for one of my units because I keep getting (valid/serious) complaints about them. It has caused one tenant (good) tenant to move out. My question is, should I or do I have to cite the reason for my terminating the lease in the termination letter? Also, can someone recommend a template for the letter? Thanks! 

Note: I'm in New York State.
