Reducing Property Taxes in Seattle area

[Victor Quan]

I was looking at property records for my rental and found that my appraised value is 48k more than my next door neighbor who has the exact same house and lot size.  I'd even push to say that the conditions are the same as well.

Is there a way to reduce the appraised value on my property so my property tax can be less? This is a property I plan to keep for a long time so re-selling is not an option.

Pros/cons to this strategy in reducing management expenses?
