This is actually quite interesting. I ran into Stefan Ingves on the street in Stockholm, the former Governor of the Swedish Riksbank, and asked him why the Swedish inflation calculations did not include housing prices.

The short answer is that they're waiting on a harmonised EU wide system for that will include housing in some measure, but that has been taking longer than expected and they didn't want to change the system in Sweden before the new system was finished...

Quite frustrating given the massive increase in housing prices since '08. Would probably have been much lower with a higher interest rate.
