1st...there is a rural medicine requirment at UofM during fourth year; howver, it is currently 2 months and the students are pushing for a reduction to one month.
2nd...UofM has the state's level 1 trauma center, so it sees cases from all over the state, parts of PA, and parts of DE. They just built a brand new ER. A multi-million dollar research building is planned and construction of a brand new school of dentistry in underway. There is a lot of money being pumped into UMB; this means research funding will go up and ur MD will continue to gain value as years progress.
Also, cost of living is MUCH, MUCH higher in DC. You can find 2 and 3 BR townhomes within blocks of UMB for 1,000-1,200/month.
Good luck in your decision erin.
