Immovable property valuation form requires registered valuer to complete questionnaire, state valuation approach and sign declaration. Form O-1 requires a registered valuer to complete a detailed questionnaire on the property (ownership, location, land area, tenure, covenants, development notifications, improvements, occupancy, rents, taxes and sales evidence), set out the valuation approach with supporting calculations (Part II), and sign a declaration affirming accuracy, no interest in the property, and personal inspection (Part III). An annexure mandates technical building specifications and allows modifications to suit the property.
