Not really. If it's viable for you then buy your first property as soon as possible and keep saving. When you want to move just buy another and rent the previous one.

In most cases people will need to get a half decent job and save for a few years first but they can keep saving and have enough for another property in few years.

And if you really have to move - then you can still sell that property. People are getting new cars every 2-3 years and it's not that different from swapping real estate.

This presumes that the value of the property doesn't go down. I had more than one friend who bought before the 2008 financial crisis who was pretty stuck with their home. And who the hell has a second down payment for a home after a couple years of mortgage payments, upkeep, and fixing the "surprises" one finds after buying a home?

Of course it is. I think the average American car age is 11 years or something like that. But, if I wanted to swap cars like that, I can go into a dealer and basically transact it in 30 minutes. Good luck doing that with a house.
