Tenants upset about utilities

[Michael Dallas]

I am a 1st time house hacker and my tenants which were also teammates were signed to a lease from Aug of last year to July of this year. Since it’s now summer and they all moved back home and are also graduating they are no longer staying at the house. I have also moved back home for the summer, so the house is empty. Should they still be responsible for splitting the utilities (which we have done the whole year) or should I shut everything off and be responsible for anything I leave on. I am worried about cutting off the power and then there be mold grow as we are in Alabama. Thank you so much for the insight!!
