Not all properties for sale show up on Trulia, and it's simply because your agent/office doesn't feel the need to invest their advertising dollars here. But you're searching Trulia, so you can bet that most potential buyers are as well. It's critical to my clients that I expose their home to as many buyers as possible, so Trulia (and many other websites) are a big part of my marketing plan. And I'm far from unique in that regard, as most agents I know use Trulia as well. Talk to your agent to see if you can arrange to get more exposure for your home.
