Mitigation: The tenant who wants to move out 2 weeks early informed me too late (during the last month), and by that time I had already rented the house to a new tenant who will move in and take over utilities on the 1st of the month.
Utilities: Since the lease was to expire on the 30th of the current month and new tenant arrives on the 1st of the month, there would have been no gap in utilities between tenants.
Question: Should I make the current tenant (final month rent has been fully paid), the one who wants to vacate 2 weeks early, keep utilities in his name and pay for AC + lawn mowing during the final 2 weeks? Excellent tenant for 2.5 years.
Cost: about $400 total for -- transferring and paying set up fees for utilities, running a SFH AC for 2 summer weeks (90s weather), and paying for 2 lawn cuts.
Pros and Cons:
Pros:maintain good relationship, don't have to worry about whether tenant is keeping up with utilities, extra time to do maintenance and repairs that I did not have before.
Cons: $400 in extra costs, risk that the tenant could argue I let him leave early and try to get a refund in rent.
Thank you again for all the helpful advice.
