I communicate often during the buying and selling process.  Do I call everyone of my clients on a set schedule?  NO, I call when I can communicate what we can do or need to be doing in the near future.  

You are right, Communication is the key to happiness.

Great post thanks for sharing. I especially like to establish the preferred method of communication in the beginning along with what times are most convenient. This prevents 'missed connections' and ensure a smoother process.
