Myth #1 - A Listing Agent Who Doesn't Show Your Home to a Boatload of People is a Bum!
I recently acquired a listing from homeowners unhappy with their listing agent because "he never showed our home". Treading gently, I tried to communicate that the primary job of the listing agent is not to sell the home but to get it sold! In fact, it's entirely possible that a first-rate agent will never personally usher a prospect through the home.
When a nervous family, with 60 days to get out of Dodge, entrusts me with the sale of their home, do you think they'd prefer to wait while I desperately massage the relatively small number of prospects I have at any given moment or rather I devote my resources to artfully exposing the home to literally millions of potential buyers?
A responsible agent isn't going to frog march every warm body she encounters into a home just to prove that she's on the job. Instead, she'll be hard at work carefully crafting a marketing program that's attuned to the home and the owners' needs. That marketing should appeal to the eye and the ear, be both wide and deep, include a strong online presence and sometimes takes a couple of weeks to fully implement.
So, if things aren't moving along quite a quickly as you'd like, a better question for your listing agent than "why aren't you showing my home" is "show me what you're doing to get my home sold".
