Open Question: How to shop for this insurance bundled?

I am not happy with my current agent and would like to shop for new. I need 3 types of insurance: 1 - a home I own in another state that I currently rent out. 2 - renters insurance for my current residence. 3 - auto insurance. The agents I have contacted have an easy enough time with my auto and renters, but when it comes to including my home in another state, they say they can't help me. I'd like one agent, one company. Any suggestions?
