In the UK, real estate appraisal is known as property valuation and a real estate appraiser is a land valuer or property valuer (usually a qualified chartered surveyor who specializes in property valuation). Property valuation in the UK is regulated by the Royal Institution of Chartered Surveyors (RICS), a professional body encompassing all of the building and property-related professions. The RICS professional guidelines for valuers are published in what is commonly known as the Red Book. The 2011 version was the RICS Valuation Standards 7th Edition (2 May 2011), superseding an edition published in 2007 with later amendments. The RICS Valuation Standards contains mandatory rules, best practice guidance and related commentary. Changes to the standards are approved by the RICS Valuation Professional Group Board, and the Red Book is updated accordingly on a regular basis. While based in the UK, RICS is a global organization and has become very active in the United States in recent years through its affiliation with the Counselors of Real Estate, a division of the National Association of Realtors.
Federal law requires appraisers to have a state license or certification when working on federally related transactions, such as appraisals for loans made by federally insured banks and financial institutions. The Appraisal Foundation (TAF) offers information on appraisal licensing. There is no such federal requirement for assessors, although some states require certification. For state-specific requirements, applicants should contact their state board.
The cost approach was once called the summation approach. The theory is that the value of a property can be estimated by summing the land value and the depreciated value of any improvements. The value of the improvements is often referred to by the abbreviation RCNLD (for "reproduction/replacement cost new less depreciation"). Reproduction refers to reproducing an exact replica; replacement cost refers to the cost of building a house or other improvement which has the same utility, but using modern design, workmanship and materials. In practice, appraisers almost always use replacement cost and then deduct a factor for any functional dis-utility associated with the age of the subject property. An exception to the general rule of using the replacement cost is for some insurance value appraisals. In those cases, reproduction of the exact asset after a destructive event like a fire is the goal.
When everything goes smoothly, the home appraisal is just another box to tick on a closing checklist. When the appraisal value is lower than expected, the transaction can be delayed or even canceled. Regardless of which situation you encounter in your home buying, selling or refinancing experience, a basic understanding of how the appraisal process functions can only work in your favor.
Thus, the definition of value used in an appraisal or Current Market Analysis (CMA) analysis and report is a set of assumptions about the market in which the subject property may transact. It affects the choice of comparable data for use in the analysis. It can also affect the method used to value the property. For example, tree value can contribute up to 27% of property value.
With effect from the 1st of August 2017, new amendements to the Federal Valuation Law came to impose the compulsory certification of valuers by a state-affiliated testing centre. Consequently, this 2 hour written-exam certification measure, aimed to counter a perception of wide-spread malpractice among the members of the national valuation profession, provides for 3 valuer-specializations: real estate valuers, plant and machinery valuers, and business and intanglble asset valuers, with the exam content requirements varying substantially for each specialization. Valuers would lose a right to practice, unless they comply with the requirement to take this compulsory certification exam at or before March 31, 2018. A general assessment of this measure is that the numbers of certified valuers in Russia are set to dwindle down to some 2000-3000 valuers nationwide (across all the specialisms mentioned), i.e. decimating some 80% of the current Valuer SRO's membership, due to the complexity of the certification exams.
As mentioned before, an appraiser can generally choose from three approaches to determine value. One or two of these approaches will usually be most applicable, with the other approach or approaches usually being less useful. The appraiser has to think about the "scope of work", the type of value, the property itself, and the quality and quantity of data available for each approach. No overarching statement can be made that one approach or another is always better than one of the other approaches.
