Pretty much, on your application you express that you want to only rotate at Inova for your last two years. Then, depending on how many people do the same, they let you know where you stand. Generally, most people want to stay in the Richmond area (especially if you're from out of state and don't have family near Inova) because to pick up and go after establishing yourself here for two years is too bothersome and the main campus is here. It's usually people who want to go back to be closer to family who want those spots. I think they're around 34 or so and most who request it seem to get it.
Something I have heard floating around though is that all OB/GYN rotations will start to be at Inova, no matter which campus you said you preferred. I'm assuming VCU will set you up with housing for those weeks if you're not assigned to Inova.
