I'm an agent. I've worked for one agency, owned two and been involved in one other and none of them have fully closed down over Christmas. In fact, even with skeleton staff and a closed office, the number-one priority is letting what is currently vacant so as to not have landlord have to bear that extra two weeks of dead time over Christmas. So I'm curious if their are any landlords out there who have been told, "sorry we're closed" while your property sits without any prospect of being rented over Christmas. And I'm more curious about what your agent has said to you about why they think it's ok to not show properties.
