Notice the rectangular mark under the address, there used to be a mailbox there.

When you have to evict someone in the zone (orange placard on door) you are going to lose money. However, you can get a little bit of joy out of this situation by removing the mailbox. Former tenants are SERIOUSLY pissed off when they return to find they have no way of getting their 'check'. I'll try getting this reaction on video for you!
