I always try to do as much "due diligence" up front when buying businesses, and if there is a broker like you're explaining where they won't share any additional data that is common (even after signing an NDA), then I'll just walk since I've wasted my time multiple times getting deeper into the process to only find out the information I had requested was not sufficient for my criteria (usually involves financials like in your case).

I'm planning on starting a thread about this duplex as its my first real dive into RE.

It's not until you would get to the actual underwriting phase of applying for the loan where they would dig deeper into your background and see what exactly it is you are trying to do with these multifamily units.  

Reading is great but I find that going out and just looking at properties will start giving you a deeper understanding.  

Don't rely on them giving you a credit check either, pay your $35.00 (or whatever it is), get them to sign a release and deep-dive into their credit history. 

Thank you @Rachel C.Thanks for digging deeper. 

The covid19 pandemic has caused me to take a deep dive in to looking at all aspects of my finances and motived me to pursue financial freedom. 

@Orly Howard, without doing a complete deep dive into the analysis, I like the 2 separate homes. 

Not sure how far along you are in the process of learning but make sure you educate yourself prior to diving in.

Last year I came out to SLC with the intention of picking up an investment property and the deeper I dug into it the more nuanced I noticed the local market being.
