Protest property tax assessment

[Simon Stahl]

I just got the 2019 assessment for a tri-plex that I bought in SA last year. Last years assessment was 93k and they want to jack it up to 116k for this year. The purchase price that I payed last May was 104k, but when I look at the filed deed, it shows only $10. There are no other tri-plexes in the area that have sold within the last year to compare to.

The increase feels excessive, but I have no experience in protesting assessments. What value would you recommend I should shoot for and with what argumentation?
