Websites like Trulia are an extra that could help get your home sold.
Obviously since we're on the Trulia website lots of people here like it and use it.
My question would be why would you hire an agent not well-versed in current internet marketing. With all due respect to Trulia, what if your home is not on Yahoo real estate? Depending upon your market, my sellers expect me to put their property EVERYWHERE, not just the MLS. Savy home sellers KNOW where to look. A savy listing agent will show them where there home will be listed.
