I was accepted to DMU in mid november. There is NO on-campus housing at des moines university. However, there are lots of housing options around the school and the des moines area. The 3000 Grand (apartment complex) is literally right next to the campus and there are some (the imperial i believe) across the street.
Coming from long island, the cost of living in des moines is amazing to me. I really could not get over the prices for renting an apartment (or even buying a house/condo).
