Refund if the STR or VRBO visitor leaves earlier than expected?

[Angela Davis]

What is reasonably expected if a traveling contractor leaves one of our apartments/houses earlier than expected? Do we refund that money per diem? Is it not our issue if their contract with a company ended earlier than they thought? We always want to do the right thing, but if they've booked the property that means we might have missed out on another renter wanting those days they've now canceled? Thanks for the advice.......
