Congrats, and welcome to the fold!
I applied to grad house, because it's not that expensive compared to most downtown Toronto housing, and its likely a lot easier than some other buildings, most of which have a lot of horror stories about poor management, pests, or robberies. Also, it's not a guarantee, just another option. So, I figured it couldn't hurt to apply! That said, I'm not banking on Grad house, merely exploring all options!
That said, if anyone's who has accepted the program is looking for a room mate somewhere in Toronto for next year, PM me, perhaps we could chat and see if it's something we're both interested in, or maybe try and get a group of us together if possible!
