10. Measure key pieces of furniture ... and check if they fit through the door. If you have not accumulated much furniture yet, or you don't mind swapping a few things out, this may not be an issue. But if you do have a special piece, like a canopy bed, large sofa or piano, it would be heartbreaking to find out it won't make it through the door after you've signed the lease. Bring a tape measure with you to each open house, and check doorway and stairwell measurements to be sure your beloved pieces will make it in.
