I'm the listing agent for this property. There's a floor plan for this house but for some reason Trulia didn't capture it from the Multiple Listing Service site. Just so you know, this property is under agreement so I'm not sure why it's in Trulia as I changed the status to under agreement last week. My web site has a direct feed from MLS with accurate and up to date information.
Some of the third party sites, while user friendly and easy to navigate, don't have accurate info because not all MLS subscribers (i.e. Realtors) share their listings on the third party sites ( like Trulia).
