Should I inherit a tenant of a mother in law suite?

[Nicu Parente]

Hello BP,

I am looking at a property that has an attached mother in law suite with a separate entrance, kitchen, full bath and a 3 year tenant.  It looks like this SFH was rented out as two separate units, the main floor being unit 1 and the basement as unit 2 (they even have separate mailboxes), I will be occupying the main floor.

From what I can tell, the tenant is a single young working professional. My plan is to get the tenant into a month-to-month lease at least for the first 6-12 months then go to a yearly lease. 

So the question of is it a good idea to inherit a tenant from a mother in law suite?

Thanks,

Nicu
