It's been my experience that Trulia retains information on homes offered by real estate agents even after the home comes off the market. This frequently causes confusion among consumers and agents.
Most likely, this home is not currently for sale through a real estate company. In general, if the home is actively for sale, there will be one or both of these links available. "Contact Agent" and/or "View Details".
Another way to look is to search by address in quotation marks "111 Tamarack Cir" In this case, there is an active ad on another website indicating the home is/was available at $285,000. I cannot verify this is accurate.
The real estate agents in the website below would be able to look and verify information for you.
