• Don't go alone: This is true especially if you're a woman. Sorry, I know this stinks because I always have to bring someone along too, but safety is always the first priority.  Not only will you get the job done faster if you're out on a bid and bring someone else, you have both an extra set of eyes and hands as well as a witness in case anything happens.

• Look for signs of occupancy before entering.  Common indicators of a vacant property include overgrown yards, disheveled or empty interiors when looking inside through a window, etc.  You should also listen for the sounds of pets inside, although sadly, sometimes people will leave their pets inside the foreclosed home (I know, unreal).  If the inside clearly looks like someone still lives there, you must re-verify occupancy with the bank and let them know you think someone might still be there.  It's the bank's job to evict them, not yours.

• Document, Document, DOCUMENT!  You may be in a situation where you have to prove that you were diligent in determining that the house was vacant.  Photos certainly help prove a lot (overgrown yard, disheveled interior, rotting food in the fridge), as will your notes that indicate you followed proper procedure (properly opening the door - no smashing windows!, verbally annoucing your arrival, record-keeping of the items removed, etc.)

Above all else, do not get into a confrontation with a homeowner, neighbor or other person on or near the property.  You job is to clean out the property, not to evict people or to represent the bank.  I always tell people, "I'm just the cleaning company trying to do my job.  I'm sorry, I don't know anything or have any other information for you".  If they become aggressive, get outta there!  Notify the asset manager and let them know that THEY have to take care of the situation before you'll return.
