I'm looking to do a cash out refi on a duplex I have, but I cannot find any reviews online or much of an online presence for them.

Take time to learn through military-focused resources like Military House Hacking or Active Duty Passive Income, and connect with other military investors online or on base.

Is it public record that I can find online?

Attend seminars, join online forums, and read up on the latest market trends to stay informed.Remember, real estate investing is not without its challenges.

Your state law and notice can be found online. 

I can provide him with an online log in so he can review the books from his office.

It is not very difficult or complicated to evaluate commercial real estate, there are plenty of good books available that can teach you how, textbooks, online courses, community college classes, even excellent youtube videos etc, and it is actually quite enjoyable in the process to learn.

More of a re-set that seeing the numbers (prices) at which my comp set actually books- leads to.

I can't post the link here, you can dm me or search online. 

For example, say I have a foreclosure, or expired listing lead that I would like to find accurate phone numbers for for prospecting.
