I bought my duplex in November 2017. I moved in immediately. I bought the property from a distant landlord who was paying 6% Property tax which worked out to be $2,265.60 a year.

I filed for 4% property tax since this is my primary residence, I was denied the 4% on the entire property but was told I will have to pay 6% on the rental side and 4% for my side....This makes sense so I did not think anything of it... Well yesterday, I got a letter in the mail from my loan company, that said I had a escrow shortage and my payment was going up $263!!! I looked on the accessors website and my property taxable value has not changed. As you can imagine, I am really trying to find out what I am missing here. The increase is due to a "Property tax increase"....

Somethings not right...my property tax was supposed to go down, not up!

Anyone have any advice on what to do? I am going to call the accessors office to figure out whats going on, but does this sound wrong or am I missing something here? 

Your Rate should go down slightly but perhaps the assessed Value went up?

Is that 263 per month or per year?

@Caleb Heimsoth $263 per month

I think I figured it out...They are charging me for 4% for the whole property as well as 6% for the whole property. 

See below for the screenshots I took of my neighbors information from the tax accessors webiste verses mine. Look under "Land". (My neighbors is a duplex as well)
