I suggest you develop a fairly detailed scope of responsibilities for that PM, including how often you expect him to be there and exactly what kind of interactions, inspections, reporting and other activities & responsibilities you expect of him. 

 @Dave Foster, Solid answer.

All I can say is, keep reading and interacting on the forums with others.

I'm probably missing a few obvious things so please let me know if this fosters additional questions or discussion.

@Dave Foster, you've nailed my issue precisely. 

If you have a talented PM company in place, there shouldn't be too terribly much interaction with your tenants.

How many hours would it take to get general information about dozens of Baltimore neighborhoods through personal interactions?

Even the LADWP is a pain to deal with and anything electric can linger for months if not years in this cityFor that reason, i would recommend to absolutely avoid any interaction with the city unless you do really heavy work that would have significant impact on the appraisal like maybe adding bedrooms and bathrooms or adding lots of square feetThe current system doesn't reward doing the things by the book; you actually will be way ahead doing things on your own and just comply if you get an order to comply one day (very unlikely anyway).

But I would be circumspect about how I requested the records (need them for personal research project), how the information appeared when disseminated (all indications that it came from the State would be removed), and how I phrased my interactions with property owner's who were identified through use of public records (I'd never mention that the owner's identity or address was obtained from the State or County, only that obtained the information legally at considerable cost).

So in case you need one, @Dave Foster is your guy for that.Good luck!
