Not renewing a lease - do you owe tenant an honest explanation?

[Sam Leon]

One year lease about to be up and I am not renewing.  Tenant has been a real pain to deal with.  Too many lies and excuses, you know what I mean.

Now do you tell the tenant why you won't be renewing?  Or do you make something up like you are considering moving in yourself, or you need to do some major renovations, or you might make it a short term rental, etc etc etc...it's not the confrontation I worry about but I don't want to risk property damages out of spite.
