Realtors who knock on your door are clearly out to get to know both neighborhoods and people. It’s called prospecting. Do you really want someone representing you who just waits around for the phone to ring, or someone who actively makes an effort to meet new people and prospects every day?
I’d rather have a Realtor who knocks on doors and looks under rocks for someone to buy my house, than have someone who spends all day at the salon having her nails done. Wouldn’t you?
