When should I let tenant know that I am not offering a renewal...

[Steve DellaPelle]

Hello BP,

My tenants lease is expiring on November 1, 2018. I do not want to sign a new lease with them but rather go on a month-to-month agreement since I will eventually be ending my tenancy with them early 2019 (March, April, etc).

I do not want to give them too much information, just the fact that I am not sending a renewal lease and will be going month to month instead.

When would be the best time to communicate this to them? Now or closer to the end date?
