I don't know Real Estate situation in your market but here in Florida we have about a 3-year supply of homes for sale today precluding what the builders are still pushing out.

Changes I have noticed from the switch to a buyers market from a long run sellers market.

1). All the FSBO's are gone, if it ain't listed with a Realtor it does not sell.
2). All the Listing agents are becoming Buyer's agents.
3). Open Houses no longer attract any action.
4). Most homes are vacant.

You might want to include a few of these things in your discussion. Besides the obvious, when I get in front of agents I discuss pre-listing inspections as a way to set one property apart from another. It allows the seller to control the cost of any obvious repairs that will become apparent during a standard home inspection and removes the adversarial position that normally exists between a home inspector and a seller. All in all it has been good for business.

Good luck with your meeting.
