They usually don't cash flow, but a big part of your housing is subsidized by your tenant. 

I will not lose the forest (the fact that I would be buying a property that is deeply negative equity) for the trees (the fact that it might "Cash flow"). - I understand basic tax principles.

It's cash flow what does that look like?

Fully under AC, clean rooms for advanced manufacturing, excellent building in every sense of the word, from a tenant perspective. 

Hi Troy, I recommend starting with a turnkey cash flow rental.

Wondering what, if anything, I could do to spruce up the place to make it more attractive to a potential tenant OR if there are ideas of what I could personally do to it that would create some nice cash flow for me (co-working spaces, etc.).

Are you cash flowing the property?

Since much of the house would be common areas, you might even consider hiring a cleaning service to go through periodically.

Turnkey rentals would be your best option, somewhere with immediate cash flow and some appreciation upside if you hold it.

Some cash flow more than others, but they all cash flow pretty well.
