My 14 year old now makes over $100/month passive income from her % owned and my 10 year old is at like $65/month.In this process we are building their interest in real estate, teaching them the value of putting their money to work for them, and all the while growing our investment if we need it for their college money some day! 

Depending on your flavor, this could be good or bad.Connect with a great property manager early on, as many won't work just any property in any part of the City.Being an east coast city, our housing stock is fairly old and unless it's been properly rehabbed, will have typical "old house" maintenance.None of this is meant to discourage you from investing in multi units in Baltimore, but I'd try to set realistic expectations about the market here.TLDR; we have a wide variety of "multi-unit" structures in Baltimore.

My name is Hudson Brannon and I am 18 years old.

When searching for clients I usually suggest starting with ones inner circle and good old grass roots marketing. 

@Kasi V. how old are the homes that you are purchasing?

The deals you're looking at, how much longer on the contract and how old is the building? 

But besides that, what are y'alls opinion/concerns on me buying a condo right out of school? 

This could lead to higher tax bills for businesses and renters, who do not benefit from the homestead exemption [5].Local Jurisdiction AutonomyThe amendment allows counties, consolidated governments, municipalities, or local school systems to opt out of the exemption if they choose to do so.

My son currently lives in the townhouse b/c he is going to school and works in the area.Since he is young and starting out in life, I would like for him to only cover the basic costs (taxes, HOA, utilities) just enough for me to break even (I believe that will put him slightly little lower than market rent rates).
