They have lowered my taxes every year since I signed up with them (around 5years). This cost is very reasonable and is based on a set percentage of the money saved. They are easy to contact and have a newsletter filled with information on saving money on your property taxes as well as step by step procedures on how to do it yourself. They do automatically protest yearly tax, unless you notify in writing and in timely fashion, that you no longer require their services. I receive every year a notice from them stating they will be protesting unless notification is given not to. I’m waiting to see how they do, as property taxes have really taken a leap.
