I guess if you are listing 15 properties a month, you not only have your hands full with work, but also have the income to be able to ignore the possible double-dip.
Personally, I wouldn't let other agents hang their riders on my signs. I have my own. The phone number goes to a toll-free number that rings me. If the buyer isn't interested in my listing, I REFER that buyer out and get a referral fee.
The day I get too busy to do the above, I'll hire an assistant to handle the referring and have the toll-free number ring the assistant. Theoretically, busier means more listings and more referral business, so the assistant should pay for him/herself.
I mean, the yard sign is one of the most powerful sources of all sorts of leads. Why would you just give that away?
