TOWARDS A STANDARD PROPERTY INCOME VALUATION MODEL: RATIONALISATION OR STAGNATION?

Abstract

In a previous paper Sykes derived a mathematically consistent investment valuation model for freehold properties which he referred to as the Rational Model. This new model overcomes certain serious failings of other methods commonly in use. The present paper readdresses the arguments of the earlier paper in a manner rather more familiar to a practising valuer and compares current methods of valuation with the Rational Model. It is also shown that the Rational Model can be simply adapted for the valuation of leasehold interests without resorting to a separate (and usually quite artificial) ‘sinking fund’ rate.
