I am going to meet with him tomorrow and have some questions I am going to ask him, but I am looking for some suggestions as well.

This can be a conventional loan, so I would suggest that you with conventional lenders for better rates and terms. 

It sounds like they are suggesting to you to establish series LLC = one tax return with multiple entities underneath one parent LLC.

Just a suggestion, I've had some luck using the approach; "obviously you don't like dealing with me, let's come up with a solution that works for both of us so that we can move on with our lives and not have to speak with one another ever again."

I am currently on the hunt for my first small multifamily property in South Jersey (Camden and Burlington counties) as well.While I have not used a property manager yet, a few local investors suggested Mike Williams of Sureway Property Management.  

Suggest you have it appraised.

The lender I am working with suggested a 5-year ARM with interest only payments.  

I am looking for working capital to expand my flipping business and was wondering if anyone had any suggestions or recommendations on this specific thing.

It would be helpful to know: rent growth, exit cap, business plan and your experience with such assets before offering any suggestions.

Does anyone have any suggestions on neighborhoods for good cash flow?
