The downside is it takes time and a lot of money for it to produce results.

How much income is the property currently producing? 

Lot rents at $250 and running at a 40% expense ratio produces only $16k/year net  Is it worth it for the massive amount of work this place will require?

I own 30 properties in western PA that produce cash flow, but no appreciation. 

They are all in c class areas and produce very well.If you plan to enter the C class investment world, I would suggest that you have a plan to scale up.

Just ball parking on the numbers you gave, in which it appears that 11 units are producing the current income.

Long-term I'm hoping to build a portfolio of cash-flowing properties that produce enough income to live off of! 

Do not try to be an innovator in Detroit or anywhere else.
