Nobel Prize winner Robert Shiller says that despite a strong housing market since 2012, homebuyers do not seem as excited.
A low unemployment rate in the U.S. is helping drive the market up.
Shiller also says Donald Trump and his family's lifestyle might be contributing to people feeling like, they too, can live in extravagant homes.
However, he says, "there could be a change in sentiment toward housing which could bring prices down."
He also addresses housing affordability as a global issue.
