Keeping old owner occupied house buying duplex.

[Kirk R.]

Hi,

-I am planning to buy a duplex and rent out some rooms.  I will be owner occupying the duplex.

-I currently owner occupy a property and rent out some rooms.  I am planning to keep this property and continue renting rooms.

How do I most economically insure both places?

Will my current insurer cancel my policy if they know it's a rental?  Is there a cheap way to go?  My current policy is about $820 per year.
