A Seattle software company provides a web based service that checks whether your property valuation is too high for free and then helps you appeal your valuation and generates an appeal report. ValueAppeal claims 40% of property owners overpay their property taxes. Appealing your property valuation can be a painful process, to find the information, understand it and organize it in a way to make your appeal successful. That also assumes that you have enough information to know that your property is over valued in the first place. ValueAppeal seeks to take the uncertainty and pain out of the process. From their web site, you can enter your address and get an evaluation of whether your valuation is too high in seconds for free. Then, for $99 they walk you through a 10 minute online process to generate a property valuation appeal report that you can use to appeal your property valuation. If your appeal is not successful, ValueAppeal will refund their $99 fee. Their report provides data on other comparable sales that support reducing your valuation as well as unequal assessment information. It also has an area where you can put in unique aspects of your property, such as something like fire damage, that the assessor may not have taken into account. Unfortunately, the service is not yet offered in Chelan County. The company is working on expanding the county coverage area, with an announcement slated for later this month. It currently offers service in King, Pierce and Snohomish counties of Washington state, as well as most of California. The company also compiles detailed information on property tax information in the areas that it covers. For example, earlier this year ValueAppeal issued a report which said that West Seattle's Fauntleroy neighborhood was most overassessed neighborhood in Seattle.
