Tips for Tenant-Occupied Purchases?

[Jean Carlo Vilalta]

Hey BP! I'm on my way to purchasing my first multifamily to househack, and a few of the properties I've looked at are currently tenant-occupied. I've been reading up on BP and otherwise and understand the need to get things like their existing leases along with as much information as possible about them in order to best gauge how to proceed and if the deal is even worth it to start in that regard. That said, there are several factors that I'm wondering about as I explore this as an option. My first question has to do with rent as there are many descriptions of "long-standing tenants" who are potentially paying a lower rent than the market calls for. If I were to purchase such a property, would I have to wait for their current lease to expire prior to making any changes? If so, would evicting them be an option? I'd obviously want to steer clear from burning any bridges or inciting potential harm to a property by jumping right to an eviction. 

I'm curious if anyone has any insight on the matter or perhaps has gone through a tenant-occupied purchase/experience and can share some lessons learned.

Thanks!
