With so many choices that you have with regard to real estate agents, you may want to check a couple of items.
Ask to see their realtor card - maybe they aren't really real estate agents.
Ask to see if they can lift you off of the ground. This one is important in case you are in a home and it catches fire and you get overcome by smoke inhalation.. They will need to carry you out.
Well... At least make sure they are a realtor )
