A properly secured property, where you make sure all windows are repaired and doors and windows are locked, is basically safe from squatters
A common tactic is to do it in two passes. First one dude comes along, smashes in the locks and walks away. Then a couple of night later a second group of dudes come along and find the house unlocked and 'legally' move in. So you basically have to have security people check your buildings at least once a night.
