Contra Costa County Property

Current market value of my property has falls below taxable value, What should I do?

I live in Northern California (Contra Costa County). Because of the Housing Crisis, I believe that the current market value of my property has falls below taxable value as shown on your tax bill.

I heard you can actually lower the Tax of the property, by filling out a form.
But, I do NOT know where the form or who i should contact with.

Could someone give me some guideline or steps, which shows what I should do in order to lower my property tax?

Property taxes are assessed annualy at your local appraisal district office. Google your local appraisal district and log on to their site. You should be able to find a dispute form. Fill out the form and submit it. You will be called to stand in front of a dispute committee and explain your reason. You should be prepared to answer their questions.

There is a yearly deadline to dispute, find out what it is. Ours in Houston, TX was on June 2nd.
