Homeowners insurance for multi family owner occupied in PA

[Rob Snyder]

I am in the process of purchasing my first investment property.  It is a 4 unit multi family where I intend to live in 1 of the units and rent the other 3.  I am having difficulty finding a homeowners insurance plan.  Does anyone know of any insurance companies serving southeast PA that would insure this type of property?  Ideally, I'd be looking to bundle auto insurance with the homeowners policy as well.  Finally, any thoughts on any additional insurance that may be needed or recommended?  I'm thinking 'landlord' insurance, a liability or umbrella policy?

Thanks in advance!
