Property Tax Appeal in San Mateo County

[Anwar Mai]

I purchased my home in San Mateo County last year for $1,525,000 in a private party sale. The county assessed it at $1,700,000. It was on the open market for a month with no takers. There were 2 homes in my development that sold for $1,700,000, but at least 2 other homes in the area at 3 months earlier with the same size sold for $1,545,000. Do you think I can win my appeal? 

I'm bringing my comps and the appraisal that was done at the time of purchase showing compatibles at that time. I'm also bringing an estimate on new replacement of 30 windows in the home to replace some failed windows that show $120,000 for the estimate. Is there anything else I should bring?

The assessor asserts that they have fair market value because the seller saved on commission and that saved commission is getting added to the value on the purchase price as part of their appraisal.
