In my area, CL is flooded daily. No matter what you post, it's gone off the page in about an hour.
Where else can you advertise. I've seen my PMs advertise online in renter sites-which all cost money. A lot of money. That's why it's always been worth it for a PM to find us a tenant while we take over after that. They charge a month's rent but it works out to the same price for us to advertise plus they do all the showing of the place. I think they get most of their tenants from people walking in and looking for a rental rather than advertising, which wouldn't work for a regular landlord. So how else can it be done without being so costly?
