I guess York is the only university there and I live therer. I'm not so sure about high schools and their residences. Yes I live in a one-bed room with rate:$669 per month but it jumps 2% more every September. THere're apartments for rental around the campus with rate around $900 I guess. You may want to try your luck in these buildings cause it's summer and students are not coming en mass. Regarding campus residences, even students have to line up. Hope it helps.
