I think going with the auto policy 1st would be easier to market. Everyone wants to save on auto insurance. Maybe headline a doorhanger with "Find Out How To Get "Free" Renters Insurance" Ask me how I can get your auto and renters insurance for the same price as you pay now for just auto insurance.....
Good idea...add in there that it only takes 15 minutes to find out. 15 minutes=free renters insurance or X amount of savings.
