I prefer corporate rentals precisely because there is less idiosyncratic risk. They boringly have a strong incentive to keep you renting the same place as long as possible.

The cost of owning absolutely does increase over time. The mortgage payment is just one part of the fully burdened cost. Furthermore, there is a real risk of an unexpected $20k expense that you have to pay for. Owning is less predictable than renting because the liability and risk surface area is much larger.
