Course information

Valuing property that is subject to some form of contamination is particularly difficult. Much depends on the nature of the contamination/impairment and the type, and cost, of necessary remediation works. Our instructors are experts with considerable experience in dealing with this type of valuation work. They will look at issues concerning the highest and best use of the property as impaired and consider how the three main valuation approaches need to be adapted to reflect the contamination. In addition to looking at the cost of necessary remediation work, they will also consider the liability impacts, use limitations, and possible stigma attaching to contaminated properties. They will also cover how to deal with such properties within a mass appraisal environment. Up to date information about the law concerning contaminated properties and practical guidance on the preparation of valuations relating to such properties will be provided.
