This has not been my experience as a renter and as an owner. The realtor's margins for renting are quite low, which means they try to make things as smooth as possible for everyone, to minimize their work: in particular, they try to get the house/apartment rented as soon as possible, to make as few visits as possible; the also have an interest in the tenant staying the longest time possible. As always, I guess it depends on your real estate agent, though!
