Yes, the university bought several houses last year, I believe. Paid something like $3 mil for 12 houses, I think. I'll see if I can find the info.
Fastest thing I could find googling..
"Duke University actually bought the house that the team captains lived in. Duke owns the house where this alleged gang rape occurred. They tried to buy several houses in the community and sell them to single families, who would agree to fix up the houses and live in the community so that the other residents in the community wouldn‘t have to continuously call police about drunken parties and all kinds of disorderly conduct."

But it has been reported many times elsewhere, including on this site.
