@Robert Bodmer Well first Robert I would like to say congrats on getting your first house hack completed. Where exactly in Baltimore did you find your property? I only ask because I live in Alexandria, VA and I am looking for a less expensive local market to get my first deal done before looking outside of the DMV area. I know all about Baltimore and I know that can be a hit or miss area due to Baltimore trying to get itself together outside of just the Harbor.
My advice for you would be to ask yourself is your current goal to have a certain amount of properties first before expanding to less well known areas? Does the Baltimore market meet your current criteria for your investment strategies? Staying local does have its advantages and it seems like you have your team in place in Baltimore already. However, knowing there are markets close by that may meet your criteria as well, I see no harm in venturing out and Lancaster, PA as you said is not too far away. Maybe if you do go out there, consider getting a local Property Manager on your team which could put your mind at ease if driving out there over and over again, although understanding it is additional costs.
Hope this helps!!
