Websites like Zillow.com claim to provide estimates of what your home is worth, and while this estimate might be somewhat accurate, the only way to get a true assessment of the value of your home is to have an appraisal done by a certified third-party professional. There are some situations where an appraisal is mandated, such as when you are buying or selling a home, refinancing or applying for a loan using real estate as security. The appraiser's assessment of your home and the surrounding area is a fine tuned report compared to what you get from a website.
