The cycles work for cashbuyers like sideshow in particular. For people who need a mortgage, affordability depends to a great extent on mortgage rates as well.
I am possibly going to move to another European country within the next 6 months. I checked out places there: buying on a 10-year fixed is substantially cheaper there than renting, and the quality of a renter's life is much better there than in the UK (better flats, more rights etc.). Also, there has been no property bubble. So, ironically enough, I might seriously consider buying there sometime in the not too distant future.
