Chava and I recently attended a client party in Buffalo. (A Coaching Client)  It was really nicely done.  Over a hundred and fifty people, a live band with a female singer that made every song sound like the original artist, a delicious buffet, good wine, all in a town park cabin that was beautifully decorated. 
Chava asked me a good question.  “Will the Agent get any business directly from this party?” 
So today on our coaching call, I asked the Agent that question.  In the past couple of weeks since the party has she gotten any business that she can say came directly from her party. Her reply was that she got four listing appointments directly from the party.
In fact, the caterer had come up to her and said, “You really love what you do, don’t you? These people are really clients of yours aren’t they?”  Then they said, “I’m going to move to a bigger place this year and I want you to be my Agent.” 
I have always been a strong proponent of throwing Client Parties.  You have to really want to have one, not just do it for the business. To me the benefits out way the cost. You create good will and camaraderie with your clientele. It will get your more referrals and repeat business. 
By the way, this Agents party cost her nearly $5,000.  So far the business generated from the party is over $15,000.  And we all had a great time.
I often discuss Client Parties on the 1st Fifteen Daily Coaching  Calls which are free.
