We also had to replace:
Drywall due to mold issues
Leaking Laundry Valves (see above)
A leaking hose bib which necessitated sweating on new fittings
New fittings on the hot water heater (to add a shutoff)
Various other electrical work (replace outlets, retorque loose neutral, brought grounding most of the way up to modern code - house had no buried ground rod)
To make my point further - I've had many of these issues at an apartment, in my time living in apartments I've had the following work done in or around my unit:
Replacement of in wall heater
Replacement of Garburator
Replacement of Hot Water Heater
Replacement of Shower Vales
Replacement of AC Condenser
Replacement of Dishwasher
Replacement of Hot Water Heater (and remediation of the water damage from it)
Replacement of Water Faucets
Replacement of Load Center (Fuse Box)
Repair of Refrigerator and Stove
Installation of new landscaping (new sod, bushes, etc)
Repair/Replacement of Sprinklers
Repaving of parking area
Replacement of Roof
Painting
Replacement of Siding
Cleaning of HVAC Ducting
The total cost to me on all of these issues was zero dollars - and thats my point. Those multitude of repairs are not free when you own your home, and can often be quite costly.
