It's not unusual for rentals here to include your basic utilties like electric, water and gas (if it's available), so check on that too. I don't know if OSU would make you live on campus after going to a JC and coming in as a Junior. I know that as a Freshman they do have to live on campus but after the first year, I think you can move off if you like. I had a Freshman living here one year because she got there and found out they'd messed up and had too many freshman for the dorms and didn't have room. So, she rented a room from us and had a huge bedroom 1.5 baths and free use of the kitchen if she wanted though I think she had a meal plan and just ate on campus, I don't remember her ever using the kitchen. Not something I do often but for a real good kid who wasn't a partier, it worked out fine.
For the board, right now because of the drought I'm at $300 for 'pasture' though the only difference between my pasture boarders and full boarders at this point is the stall. Everyone gets free choice grass hay round bales, Strategy 2X/day and bermuda grass at night if stalled over night. I have enough stalls that even the pasture boarders go inside in really nasty weather. And if I'm short a stall or 2, I have a couple horses who are mellow enough that they can play "aisle monitor" and give up their stalls to someone else if need be. (MY horses only, obviously, if you pay for a stall, it's yours.)
I'm hoping the drought will quit pretty soon and grass will be plentiful again so I can lower my prices. Right now it's almost like boarding in So. CA or AZ because I have no actual pasture anymore. I'm also full right now, so not taking in any new boarders until I either sell a couple or someone else moves a horse.
