Narrative:
After we got airborne while cleaning up the aircraft; the aft cargo door annunciator light illuminated. Since we were still in the pattern; we decided to stay low and complete the QRH checklist and determine whether we should continue the departure. Ran the checklist and could not determine whether the jet was pressurizing normally; so rather than take a risk with something that could go very wrong at altitude (masks/cabin mask jungle/emergency descent; etc.); we decided to err on the side of caution and land the jet to have the door checked by maintenance. As it turned out; the door was slightly open and there was a strap caught between the door and the sensor that was preventing the door from closing properly.
