Baltimore City is a challenging city to do rehabs from a regulatory perspective and tenant placement is also a big challenge given the economics and demographics. 

In some of the towns that have been thrown out above, you often have only a $100 spread in the rents for a nice vs. dumpy place with the same measurable features, such as SQ FT, bedrooms, etc.What this pushes landlords in these areas to do is focus on doors/volume, instead of focusing on the things that really build value.The lack of regulatory oversight, I get - as a business owner.

However, the long term rents would still make this property a viable investment so I was OK with regulatory risk.

Or just hire a good LOCAL civil consulting firm that can quarterback all of that for you while preparing your permit and construction drawings for regulatory agency approval.
