It is a bit tough to find out about there programs, as they have less-than-ideal websites and aren't mentioned as much. I don't think either program is considered that weak or that good. My general sense is that they are fairly average programs that are somewhat competitive to match into b/c of location. I would not recommend Howard.
On a Resident salary and work schedule, I don't think living in DC would be that much fun. You can definitely have enough money for a modest life, but you'll be priced out of some things and working through some of the enjoyable times (happy hours, weekends, etc.) It can be tough to meet people and make connections outside of work if you don't have a lot of outside-of-work friends coming in. I would not want to hang out only with other Residents and Healthcare workers.
