Majority of these higher income homes are most likely on no call list. Do you think I would have any success sending a hand written note stating I will be stopping by on a certain date between these hours. If they would prefer me not to, call me and say no thanks. Im wanting to focus on household incomes above 200K and thinking of doing 5 a day after Ieave office and before going home for the day. Would I be better off just cold knocking and forgoing the advanced notice?
