If you believe the assessed value of your property is too high or if you believe you should have received an exemption that does not show, you should contact the Property Appraiser’s office at once. The matter can be discussed and probably be resolved at that time. If you still feel your value is too high, you can file a petition with the Value Adjustment Board. 

No. you must own the property on which you make an application. If you own a mobile home, but not the land on which it sits, you would not qualify for the homestead exemption. The mobile home would not be assessed on the tax roll. You would be required to purchase an annual mobile home tag through the Tax Collector’s office.
