I'm a long time Real Estate Broker, and Property Manager (any Large So Cal Properties need management, get in touch with me please) @! 

I understand that, but my closing was delayed by one week, and it was communicated by me and the mortgage broker, multiple times that we will close at the specified date; yet the Seller still would not relent on the per diem.

My old broker only buys places in cash because he wants the cashflow.

A commercial broker in your area would really help guide you on your first deal.Roughly it looks like this property has a big risk of losing all tenants.

you talk to a Commerical broker in the area 

That said, some attorneys advise that a comparative market analysis or a broker's price opinion is sufficient.

Early on in my research, I'm seeing that in the state of NJ you need to have your broker's license in order to legally be able to manage other people's properties.

Make relationships with brokers and they can help you find MHPs if you give them your preferences.

There are occasionally banks or independent mortgage brokers that can go up to 80% or more on LTV.

Once you find that market reach out to an investor friendly real estate broker that can guide you.
