How is the Interest Rate factored into this type of loan ......

So many questions.Is it manufacturing suits, office space, retail, etc.There are many factors but mostly you look at sustainability.How long are the leases, would you be able to cover all expenses and pay yourself?

I can throw out some general numbers for you, knowing that it will depend on a variety of factors for your individual situation.

You need to factor for property management.The goal is good, just make sure the math works.

I can tell that you are a numbers guy.I would encourage you to spend a few minutes with every deal working on your gut-check factor. 

Properties in high crime areas aren't worth much so you can't buy them for the appreciation factor.
