$50-75k clean up? Yeah right. Nothing a little cleaning wouldn't fix. No actual structure damage, just rubbish.

I don't know who the bigger arseholes are ..renters, for being such disgusting abussive slobs, who should pay for the actual damage, or the owners coming up with such a stupid estimate of damage. I expected to see half the house caved in with all furniture and appliances floating in a leaking swimming pool

Estimates don't come from the homeowners, they come from the insurance company. Doi.
