Your question is "what technique should I use?" or "what technique works best?" That depends a little on the "farm" itself, who are they and what they respond to. There is a difference between farmers and condo owners. The key isn't really the technique. The key is what you are going to say. I totally disagree with April, catchy slogans don't work at all and are a waste of money. You want your prospects to think "I'd be an idiot to choose any agent other than Marie Barakat". If they think that they will call you. They won't start to think that because you have a "catchy slogan". They will think that if the technique you use has information that positions you as an "expert". What "expert" information do the people in your farm need? Right here in the home owners association that I live in there has been at least one house in foreclosure or short sale on every street for the last 4 years. Yet no agents have farmed it with info that would be helpful to people who would need to short sell their house. If you were that "expert" on short sales they would think "I'd be an idiot to call a different agent".
