This I can get behind, in spite of my earlier snarky comment. I've lived car-free in Baltimore for 12 years. Choosing a neighborhood carefully is important (though sounds like you'll still have a car). Biggest hassle is groceries- Baltimore has a real challenge in access to groceries, so look where the grocery stores are in order to start looking for housing- some popular neighborhoods have no grocery access, so you end up still basically car dependent. It's great to be walkable to groceries, and even if you still have a car you'll want a decent transit line or two nearby, you can download the Transit app to see what your transit options are near where you are looking. Walkable neighborhoods with grocery stores and some transit access could include Hampden, Charles Village, Mt. Vernon/Midtown, Station North, Downtown, Locus Point (parts of Fed Hill as well, groceries being the issue here); parts of Fells (again, groceries are a problem); Canton.
