How often to get new lists?

[Tyler Lay]

Hello everyone!

I was hoping someone could point me in the right direction. I pulled a tired landlord list of about 500 contacts, I'm wondering how many times you attempt to call them before you get a new list? Also how often should you call the same list? Once a day? Once a week? I'm not really sure at what point you stop and move on to another list. Any help would be appreciated!
