I think Jax and Prop will have seen some fun things....
I guess we get to look at more than our 'fair share' - many 1,000's of inspections all up.
Memorable ones:
One guy asleep on a mattress on the bedroom floor with 3 other women with him. This was a 1:00pm Open and because I knew the agent, I went in with him to 'open up'
A double storey house that had a padlocked door downstairs for all the Opens / inspections. When P&B inspector came to do his thing, tenant magically found the key (after the inspector pulled out his trusty screwdriver to beak in). Found shelf after shelf of snakes in glass aquariums, along with mice being bred presumably to feed them. The P&B guy found a live termite nest.
Had a few where you get more than you bargain for. Dirty places where you come away with 100's of fleas biting your legs.
Also a couple where the agent strategically places laminated A4 sheets on the floor, stating "DO NOT STEP HERE". Typically these are terraces in the Inner East or Inner West, where we are looking for 'potential to renovate'. The risk being that you may fall through the floor at that point.
I'm sure some more will spring to mind
