Commercial brokers that can insure knob and tube?

[Cory Binsfield]

Looking for help. 

I've been with State Auto Insurance for years and they decided to raise my renewal premium by $70,000 this year. My insurance broker is currently shopping it out with some carriers right now. The main issue is many of the properties still have knob and tube wiring despite many upgrades to wiring and panels over the years. 

Does anyone work with an established broker in the Twin Cities or MN that can help? No captive agents please. 

Being that the twin cities has tons a multi-family buildings that were built in the 1900s, I'm hoping someone can steer me in the right direction. The current policy limit is 22M or so.
