Be sure to emphasize that you are a team member in the property sale process, but will not neccessarily agree with them on a home's value, just because it has a signed contract for a certain price. Ask them to restrict criticism of you if your value is different. Remind them that their, the seller, the RE agent perspective and your perspective and responsibility when it comes to a property value are different
Help them understand that 'someone else's' value is not necessarily the accurate value, and that they should not count on their next Beamer payment being made by your appraisal.
Pass out your cards, and brochure if you have one.
Explain your knowledge of the area, the thoroughness of research you do, and the confidence you have in establishing a supportable value for the properties you appraise.
If they give you 20 minutes, use 8, then open it up for questions. If few questions, be prepared to discuss items not covered in the first 8 minutes.
Don't dress in a suit and tie...but in your normal attire. If they are dressed better than you, explain that you have to negotiate cob webs once in awhile while measuring .... they'll get the idea!
Attempt to come across confidently and knowledgeable. Nervousness will be evident if you talk too much with prepared statements. Keep your presentation short. Let them respond to you with questions, relax, and you'll have a good time. And don't drink a bunch of coffee before hand...........I think you know why!
Use prepared notes on a tablet or cards if you need to. But DO NOT read your presentation. Just chat with them.
Have fun! You'll do fine.
