Does an 18 year house price cycle predict a rise? (Podcast cut)

House prices move in an 18 year cycle. That is the theory of Fred Harrison, who used his cycle to forecast the 2008 slump after the financial crisis.

Does that stand up to scrutiny? Simon Lambert and Georgie Frost discuss the 28 year property cycle on this excerpt from the This is Money podcast.
