Insurance Agent vs Broker

[Account Closed]

Would it be best to choose an agent while building a rental portfolio, so that all properties are insured by the same company (and possible reap the benefits of multiple policies under one company)? Or is it best to use a broker to find the best value?

I'm thinking long term it might be best to use a major company and perhaps their quotes would be very competitive if I had multiple properties with them. On the other hand, an agent works for the insurance company, while the broker works for his/her clients...right?
