#1) taking a guess when you should say “I don’t Know but let me find out”.
An experienced agent should know most of the answers they are asked, but when they don’t, guessing can be the undoing of a sale. This is especially true if it’s a material fact associated with the property (square footage, age of roof, various costs of ownership).
Simple Solution
You will win the buyer respect (and have a reason to call them back) by getting the correct answer later, and you will reduce the clients liability by getting the facts right.

#2) being responsible for every detail of the transaction “let me take care of that”.
Ok we all do it, but haven’t you found yourself apologizing for the plumber or waiting for the cable company because you said you would take care of it. Worse yet having your new buyer mad because the home inspector (you recommended) missed something.
Simple Solution
Delegate if you can, your job is to find buyers for your clients’ property. Or compile a list of Plumbers, electricians, home inspectors, and all the utilities phone numbers and put it in a nice package that the buyers’ can take with them (include your info for referrals).

#3) talking instead of listening is the kiss of death; we all fall into the trap of being the tour guide and spouting information that can turn your buyers’ off. I once said that “the locals come here to skinny dip” I had read the buyers’ wrong and they were not thrilled by what I thought was an amusing story (or the possibility of trespassers after the sale).
Simple Solution
Ask questions that get the buyers’ talking, find out what is important to them and how the property you are trying to sell can fulfill their needs, desires and long term goals. Then and only then tell them why they should buy this property.

The list of mistakes and solutions will continue, let me hear from you about your experiences, and amusing stories.
