Page "Consumer price index" Paragraph 54

Statisticians in a country lacking a good dwelling price index ( which is required for all except the rental equivalent method ) will go along with a proposal to use such an index only if they can obtain the necessary additional resources that will enable them to compile one.

Even obtaining mortgage interest rate data can be a major task in a country with a multitude of mortgage lenders and many types of mortgage.

Dislike of the effect upon the behaviour of the Consumer Price Index arising from the adoption of some methods can be a powerful, if sometimes unprincipled, argument.
