Calculating property tax when analyzing a deal

[AJ Sherman]

I am currrently in the self-education mode, analyzing deals and learning the ropes.  To get the most accuracy, how do most folks estimate property taxes?

The property I'm analyzing is in the Seattle, WA area.  I looked on the county website, and I found info on the "Taxable Property Value" per the lot I'm looking at.  However, I can't find the property tax %.  When I searched online, I was pointed to a "Total Consolidated Levy" on the same county website.  It is 4.2.  Is this what I'm looking for?

My final calucation is:

("Taxable Property Value" / 1000) x "Total Consolidated Levy"

($111k / 1000) x 4.2 = $466/yr

Thanks,

Adrian
