If you are a broker who welcome agents with non-affiliation with board of realtor, or know of a broker who operates like this, could you please connect with me? 

Hi Elizabeth, BiggerPockets has a Featured Property Management Finder, which can be a good way for you to find some local experts to initiate conversations with.

It is essential that you consult with an experienced cross-border team including attorney(s) and tax expert(s) to ensure that you access the right advice!

Who can I contact for best rates and terms for non-primary home, NEW build for STR? 

Hopefully you will have some cash flow to throw at the non real estate debt. 

I ended up doing conventional (non-FHA) and it worked out great.  

With some creativity and some carpentry work (usually not that expensive), you can create value by turning a non-optimal unit into one that maximizes the square footage.

They're a little trickier than normal owner/occupied loans so you want an expert walking you thru it.  

They don't have it it's non existent. 

Best decision I ever made. they went on to basically lose the portfolio as 2 steps one back.. theft  non pay trashed units.. simply not a sustainable model.I then switched to no debt A class only takes a few of those to hit that magic 10k a month NET cash flow with basically zero drama.. and only a handful of props  to manage  .. owing 50 houses has major work load if they are section 8..
