You are paying $600 or more for the 20 leads.. How much do you figure your time is worth? If $60, that is 10 hours of knocking doors.. The question is can you develop 10 solid prospects in 10 hours of knocking? If you can, you are paying no more than you are paying for leads.. The advantage is you have more control over whom you choose to do business with. You can pass by the really trashy, bug ridden homes. Either way you go, there is a cost involved.My skin is tougher than leather . I'd love to cold knock 5 days a week if it were financially feasible. Time is our most valuable asset . I just believe you can make much more net money working 20 leads were somebody took some type of action to fill out than cold knocking . How is your time best spent to net the most ?The problem now is getting the leads at a reasonable cost .
