Real estate appraisers and attorney can help you file your appeal application to make sure you are approved. However, there are companies that are charging up to 50% of your savings to file the application which can average to as little as $1000. A company that I used this year to reduce my property taxes is Pacific Coast Securities, The Tax Reduction Specialists. They were very affordable and efficient. They only asked for a one time fee of $79 to file the application. I saved about $1300 in property taxes with their company.
