Just ran across this thread when looking for information on residencies and remembered how much I used it for feedback back when I was starting school. I'm currently an OMS III (third year) on rotations and can answer any questions you might be curious about.
Housing: everyone lives everywhere...haha. Our school is diverse in that we have mothers/fathers with kids ranging from 25yo-infants along with singles, newlyweds and currently pregnant. So depending on the lifestyle dictates what area of Tulsa you will want to live in. We have people who live in Claremore, Owasso, Broken Arrow, Sand Springs, and apartments/houses throughout the city. Westport is the apartments that are next to the school along the river that many people choose due to location, but also several students are living out at Stonehaven Villas (Highway 169 and 81st street) because of the easy highway access to school just minutes away and new facilities. Housing to rent/own I would look in the suburbs of Jenks, BA, Owasso, or midtown Tulsa in the neighborhoods of Florence Park, Lewiston, Brookside, or Cherry Street.
You can post on here or private message me if you have any other questions.
