home owner insurance on rental property

[Vinothkumar Arumugam]

I have a home with a regular conventional home loan as a primary home with a home owner Insurance policy, recently bought one more property and during this process i have informed, my previous insurance (Geico) saying, i gave to primary home to rental. now they called up and said to go as landlord insurance instead of regular homeowner insurance and they plan not to renew the current home owner insurance.

Will my mortgage company require homeowner insurance as proof?

or 

shall i call the insurance company again and say, i am going to be primary insurance on that property 

or

I will handle the escrow myself by this way I can get the landlord insurance still do the mortgage company mind about home insurance proof?
