That is explained by housing also becoming more valuable. It wasn't that long ago that owning a house was considered a necessary evil at best, not the path to riches as it is recognized as today. Historically, you were lucky if you got your money back out of a house when you decided to sell it. Nowadays, if one doesn't get a double digit percentage return on investment they are crying like it is the end of the world. That shift in mindset allows homeowners to charge more when they sell their home[1]. That is not a product of inflation.

[1] Which also further perpetuates the idea of housing being an investment with said homeowner realizing a tidy return in that ability to charge more, which sees even more people wanting in on the action so that they too can make a fortune; lather, rinse, repeat.

Yes, it became "more valuable" to corporations that want to extract wealth from them instead of living inside them. Another way for the wealthy to extract wealth from the poor.
