The remark I was responding to was "can you live in the same property for 30 years". Changing homes is not living in the same property, so I believe I chose the correct metric. Home ownership does not guarantee that you will be in the same place for 30 years.

All of this isn't even to consider the fact that most homeowners don't literally "own" their home in that timespan, as 30-year mortgages are very common. A lot of people buy homes because mortgage payments are oftentimes cheaper than rent payments (there are exceptions, obviously.)

The point is living in 7 different homes for 30 years, means at the end your home is paid off and you have no rent. Of course that is ideal, most people extend their loan terms often.

As you said - that's ideal. The home people trade-up to is usually more expensive than the home they move from (not counting empty-nesters) and - ideally - there will be a myriad of factors that can help one finish paying off their new more-expensive home within the same timespan, like more income or selling at a profit. But those aren't necessarily givens, as they're determined by things like your locale and the state of the housing market.
