It can also lead to the many horror stories of assessments of thousand and thousands of dollars because they need to put on new a new roof or do some other capex project and the HOA is broke.But with all that said, don't let it discourage you, I just want to make sure you go in with your eyes wide open and are not distracted by potential returns.

I hire an agent, even though I am in the top 1% of agents nation wide.

The property is a ~12 foot wide and ~33 foot deep 1914 brick rowhome in Baltimore City.
