<p id="">A Chicago student housing investor is trying out something new in Lincoln Park: a dorm that caters to both college students and young professionals.</p> <p id="">A joint venture including the Scion Group bought a 580-bed student housing complex at 1237 W. Fullerton Ave. that now mainly rents to DePaul University students. Scion President Robert Bronstein plans to change that by marketing the property, called 1237 West, to recent graduates who aren&#39;t quite ready to give up the communal living of their college years.</p> <p id="">&quot;I&#39;ve had this idea for years, and I really want to test it,&quot; he said.</p> <p id="">Called &quot;co-living&quot; by some, it&#39;s an idea gaining currency in big cities where apartment rents have soared, offering a low-cost alternative for young grads who don&#39;t make enough money yet to afford their own place.</p>
