Yep I picked up a nice home theatre system 5 satellite speakers & amplifier when my 2nd tenant was deported for myself. Along with some furniture and a lot of other household junk the cleaners disposed of at the tip.
Yep depends on Landlord insurance. Ive had 2 LI claims over the last 15 years and cleaning's covered. For peace of mind best get LI that covers it. Even if it doesnt, cleaners are still the way to go.
