Advise on larger loans for multi unit

[Chris Powers]

I am looking to move away from flipping and into multi unit buy and hold.  I have done quite a few flips and been very blessed to do well on them.  As the market tightens up and my knowledge and big picture idea grows I am looking at getting into a quality multi unit up to 1.5 million.  I have enough cash to put down 20% or more on the right deal.  I own a couple of businesses and have no debt to speak of.  All that said, does anyone have any experience with obtaining larger loans on these types of properties and a good way to find a lender to build a relationship with aside from the bank I do my other business with.  I'm sure I will need to provide current documents on the property in question etc.  Any advise or experience is greatly appreciated. Thanks in advance.
