Trulia (and others like Zillow) typically generate their estimates with limited data from public record. They may not take into account things like condition, upgrades, and other factors. Their estimates are rather hit or miss. There are two much better approaches. The first is getting an appraisal from a licensed appraiser, but that may be costly. The second is getting a Market Analysis from a local Realtor. In both cases, we personally look at the property and others in the neighborhood. This is typically FREE! If you're interested in selling and would like such a Market Analysis I'm happy to do so with no cost or obligation.
