Here’s a little something I put together following last week’s write-up on the drop in condo rental inventory in the downtown market. The South Loop / 60605 ZIP code saw condo rental listings fall by 27 percent from January 1 to mid-April. According to Redfin‘s weekly reports, condos listed for sale in 60605 rose by more than 20 percent over the same period. Is there a correlation? I don’t know, but who doesn’t like a good line graph every now and then?
