Just be cautious about buying a house then wanting to 100% stay in Lewisburg for rotations. I'm a first year resident now in emergency medicine and WVSOM grad but when we did site selection a few years back Lewisburg was one of the most popular sites for that reason, people bought houses or had families and wanted to stay local. There were a handful that were forced to go to a site much farther away from Lewisburg. Buying a house isn't a terrible idea if you can get roommates to pay your monthly mortgage, but you have to go into it knowing that you might have to move away third year.
The workaround is to have say Beckley as your base site then end up doing most of your rotations in Lewisburg anyway, which is possible. I can't speak on the EM experience in Lewisburg but my base site was in Huntington, WV and my EM rotation there was awesome. You can do your EM rotation at Cabell Huntington Hospital which is a level 2 trauma center and they don't have an EM residency so you get to do everything under the sun.
