San Jose Property Tax YoY change so wild

[Bei He]

I thought in California the property tax can go up max 2% every year. Never really paid much attention until today. 

My condo I bought in 2011. owned 2 years then rented out as long term rental. 

Today I plugged in historical property tax payment data and found the year of year change is wild...

How can this possible? Someone with experience please help to shed some light. 🥺
