Some might argue that this is a foolish question given the state of the economy the last 4 years. But a conversation I had this morning with a local resident made me rethink why you would want to know if Seal Beach home values had declined. This particular conversation arose because the owner was inquiring about how to appeal his property tax. If values have declined, most would be expect property to follow suit.
To determine if your Seal Beach home value has declined (or not) you will want to contact a local appraiser to conduct an appraisal. Seal Beach resident and appraiser Tom Clasby should be the first call that you make. Tom's knowledge of the local market is superb and he holds the highest certification available, certified general (helpful when presenting your case to the appeals board).
Next you must file an appeal with the Orange County Assessors Office. This must be done during the year which you wish to appeal the taxable value, and should be filed with the clerk of the assessment appeals board between July 2nd and no later the September 15th. From there you would be assigned a date and time to present your evidence to the assessor, hopefully resulting in a reduction.
So while at first you might balk at the idea of your Seal Beach home value declining, it may actually be a blessing in disguise.
