Why does a listing agent need a large office front: SHE DOESN'T!
Why - The agent will have an established system to send her hundreds of active clients your listing information automatically. 95% of buyers start looking on the internet to purchase a home and ask a friend in the area who they used.
SIGN CALLS: Agent should be available to show your home to potential client/caller immediately with a sign call. Agents who live in the sellings community have a higher probability of selling your listing.
