The valuer is a pivotal figure in the smooth operation of the property market. Any proposal for development (including putting together a viable site from land in a variety of ownerships and legal interests), application for planning permission, negotiation of a loan, buying and selling of an interest, arranging a letting or settling a rent review to the best advantage is likely to involve one or more valuers, often interacting with other professionals. The ongoing management activity is no less important, ensuring that the investment performs to its full potential and any opportunities to maximize the investment are recognized and reported on.
