This is very different because what the previous comment is suggesting is that it will be impossible to rent out a property without losing ownership of it after x years. This would make it very unappealing to rent out a property and it would cause property prices to crash. On the other hand, mortgages only cause property prices to go up because it allows people who could otherwise not afford a house to buy one outright (creating higher aggregate demand). At the same time, it makes it more appealing to own a house because you can collect rent on it and prices always go up because banks keep making loans to people to drive up your property's price.
