Sloane Stanley v Mundy and others (“the Hedonic Regression case”)

Summary

The claims involved the valuation of premiums under the Leasehold Reform Housing and Urban Development Act 1993. The UTLC listed three applications for the specific purpose of considering the validity of a hedonic regression model (“the Parthenia model”) to determine leasehold relativity. The Tribunal indicated the approach to be adopted for assessing relativity for different lease lengths and commented on the use of published relativity graphs.
