Inheriting nightmare tenants?

[Account Closed]

I'm currently looking at multi-family properties to buy. A lot of them already have tenants in it, so I'll have to inherit the lease. I heard that some sellers like to intentionally put "bad" tenants in prior to selling, and raise the rent (because those bad tenants get rejected elsewhere) to make the property look like it's performing better. Is that an actual risk or exaggerated? And how do I protect myself from these situations?
