Being a good cook isn't necessary. Being a functional cook is easy. Hell, I had to teach a friend how to cook dried pasta a while ago. He'd never even boiled a pot of water. He's in his 40's.

Are you building a dorm?
I'm having trouble seeing where a fortune could be made with kitchenless houses. Location, kitchen, and bathrooms are probably the highest on the list of driving a property value up. I'm not even sure it's legal to sell or lease out a property as residential here if there isn't a kitchen available (can be communal, as in renting out a room in a house).
