Id really focus on the neighborhood there are many homes in Baltimore for cheaper but that doesn't make them good investments.I really wouldn't buy a multi on your budget unless you dont plan on reno in decent parts of Baltimore in can be ok but remember you will be paying the gas bill on a boiler unless its split which tenants will get in a pissing contest over if there are too many the same will be true for water.  

It's good for beginners because it doesn't cost anything besides gas. https://www.biggerpockets.com/member-blogs/10015/88489-real-estate-research-on-the-cheap-driving-for-dollars

But the taxes are really high in the area ($15k per year) not to mention high gas and electric bills. 

If you quote new construction, how do you leave out the water line, water heater connecting the sewer, and the gas line, to name a few?

The listing says tenant pays both electric and gas (which I know are the two big local utility expenses), so that seems like a selling point.  

My last tenant smoked big gas in my apartment and just left 5 days ago.

Rental is located in Albuquerque New Mexico So my tenant was not home and her dog broke out of the kennel and dragged things all over the house including a couch cushion over the gas floor furnace.

Maybe you can show her that if she buys a new car she will have no money to insure it or put gas in it.
