“Where the particular hereditament is let on what is plainly a rack rent or there are similar hereditaments in similar economic sites so let which are truly comparable, that evidence should be classified in respect of cogency as a category of admissible evidence properly described as superior: in some but not all cases that category may be exclusive. Any indirect evidence, albeit relevant, should be placed in a different category: reference to the latter category may or may not be proper, or indeed unnecessary, according to the degree of weight of the former kind of evidence.”
“Where open market rental evidence exists for the subject property or similar properties, and that evidence conforms to the statutory definition of rateable value (net annual value in Scotland and Northern Ireland), or can be made to do so without adjustments of such a nature that its reliability is affected, a valuation based upon such evidence will provide the preferred method of valuation.”
