Current student here and I went there for undergrad.
The other OSUCOM person gave some solid advice about housing. I found my roommate via the facebook group and that worked out great. Tons of people met roommates at second look, dunno if you went or not.
As for places to live, there are many houses near campus students live in. A good place to look is down neil and down king avenue. I would not live east of high street, it is a very, very sketch place. Some people live in the south campus gateway apartments, but they are expensive. Don't look at central campus, that's near the frats and is very undergrad-ish.
There are a few communities you can live in, some are close, some are farther away. The farther away ones tend to be cheaper.
Close: Meridian. Many classmates will live here, small apartments for the huge price, IMO. Easy to bike in.(

Further away: Runaway bay. These are near hilliard, middle ground price for decent sized places. (

Governor's Square. (

University village (

I would get a car. You will likely use it for learning community dinners and also you will more than likely need it for rotations third year. I know almost no one who doesn't own a car, but a few people have made it work.
Hope this helps!
