Leasehold Extension - Valuation
An outline of the valuation principles to determine the price for extending a lease of a flat under the Leasehold Reform Housing and Urban Development Act 1993.
Hedonic regression is a statistical method used to isolate the effect on value of a single variable. In the case of lease extension, it is the unexpired length of the lease.
A hedonic regression model for lease extensions was created by Parthenia Valuation, ‘the Parthenia Model’. It had been used to determine ‘relativity’ i.e. the relative value of a property held on an existing long lease compared to its ‘freehold vacant possession value’; and is intended to provide, as the 1993 Act requires, a ‘no act world’ when it comes to valuing for lease extension.
In Trustees of the Sloane Stanley Estate v Mundy  the Upper Tribunal (Land Chamber) it was held that the Parthenia Model should no longer be used. However, the case is being appealed to the Court of Appeal.
