why you should not show addresses - NAR stats
Thought that would get your attention 
Was just looking at the NAR stats for internet users, what blew me away was that the highest % by far of actions was "drove by / viewed home" at 75%
How are these people driving by? They were able to access the address the property address from the internet.
Actions taken as result of using Internet site:
Drove by/viewed a home - 75%
Walked through a home viewed online- 57%
Found agent used to search/buy home - 21%
Now I am not totally against giving address information to a visitor, because obviously it is what they want - however I just wanted to cite these stats and state my opinion that it is IMPERATIVE that you capture the visitors information before you provide address details. Otherwise you run the risk of losing a prospect to the agent sign that is in front of the home.
This has been said before many times, but I hadn't seen the stat, and so wanted to share it with you.
