With regards to priority number 2 (that the property is kept in good condition): The landlord rents out a property at an expected degree of risk. They make this determination by screening the renter and drafting an appropriate rental contract (or vice-versa). If a renter plans to sublet out to 20 individuals every given month, risk skyrockets for everything from theft, pet damage, smoke damage, fire, etcetera. The landlord's home/rental insurance may not even cover these scenarios. Had the landlord known about this increased risk, they may have chosen to increase the deposit, amend the rental contract, or chosen another renter altogether.
