I moved from TIAC to State Farm about 4 years ago.  The first year the rate was great.  The second year they doubled my rate for the same coverage.  I had to go back to TIAC.

I had wildly professed State Farms rates on SOT and lots of abstractors switched over and had their rates double too.  (I was embarressed)  

Have you been with State Farm very long?  They may do the same thing to you.
