Eric, best wishes to you if you do move forward and become a Realtor.
I am encouraged that you chose a Best Answer that offered you solid and worthwhile advice.
By dong so, imo, you have already shown a desire to elevate yourself to a higher level, and that's what this business needs to improve our image with the public !
ps Jim, unless I am misunderstanding what you said.........I am sure you mean well, but advising a future agent to hold simultaneous/multiple open houses, and have the SELLERS sitting there as you run from one to the other is terrible "advice" , and just plain wrong.
Yes, you will "stand out" - you will stand out as an agent who isn't covering their own open houses, and left the owners in charge!
If an agent needs to schedule multiple open houses on the same day, for whatever reason, you need to have another agent covering for you.
Sellers are hiring YOU to oversee all aspects of their home's marketing. It's not their responsibility to sit on their own open house...and it's not even good business.
