inherited tenants' lease doesn't specify renewal terms?

[Sean Haardt]

I'm trying to buy a duplex and the tenant's original lease is an annual lease originally from July 1st 2014 to June 30th 2014 but doesn't specify a renewal term. I want to move into one of the units, so if it just renews automatically, does it renew annually? If it does, am I out of luck if I want to move one of the tenants out and house hack? Thanks BP.
