Do I have to honor prior owner's contract with tenant?

[Ian Briggs]

Hello everyone! I'm new to BP, and love the forums.

My question is this: I'm looking to purchase an owner occupied multifamily property. Many of the properties are fully rented already. My question is this: once I close on a property, do I have to wait until the tenant's current lease is up in order to move into the property? Or do I have to look for properties that aren't at fully rented? I'm not trying to put the current tenants into a bad situation or anything. Does it vary state to state? I'm in Texas.

Thanks for your help!
