Looking to purchase a rowhome/owner occupied rental in Baltimore

My wife and I own a townhouse in Calvert county but we're looking to purchase a row home in Ridgley's Delight/Pigtown area, as my wife has recently opened a boutique in downtown Baltimore.

Our plan is to purchase a 3 br owner occupied rental and rent out the other two rooms, preferably to medical professionals/residents from UMMC. 

I'm not familiar with the Baltimore market at all; it seems that Pigtown is an area that is currently being gentrified and prices are lower than Fed Hill/Fells Point/Dundalk, etc. - I know that Baltimore City doesn't have the greatest reputation...if anyone has any intel/advice on buying an investment property in this area, please share.

Thanks!
