Because the appraisal primarily protects the lender's interests, the lender will usually order the appraisal. According to the Appraisal Institute, an association of professional real estate appraisers, a qualified appraiser should be licensed or certified (as required in all 50 states) and be familiar with the local area. Federal regulations state that the appraiser must be impartial and have no direct or indirect interest in the transaction. Fannie Mae requires appraisers to certify that they have experience appraising similar properties in the same geographic area.
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.

Real estate valuation in New Zealand is regulated by the New Zealand Institute of Valuers ('NZIV') and the Valuers Registration Board of New Zealand ('VRB'), both of which are statutory bodies established under the Valuers Act 1948 (NZ). The NZIV remains the statutory professional body for valuers in New Zealand, with perpetual succession under the Act (which is under review as at 2015). The NZIV can make Rules as lower level legislation and has a Code of Ethics. The NZIV Rules were last changed in 2012 and remain current. The VRB has jurisdiction in relation to serious matters affecting the registration of a valuer including discipline where a valuer has acted in such a way as to meet the threshold. The Valuers Act 1948 sets the threshold under s31 as matters where a valuer could be struck off the register of valuers. The NZIV has power for discipline for relatively more minor matters. The NZIV governs NZIV members and has power to discipline members and fine them up to $500, admonish members or terminate their membership. The designations "Registered Valuer" and "Public Valuer" are legally protected under the legislation, being reserved for Valuers Registered under the Act. The NZIV, under the Act, can admit non-valuer members (such as non-valuer land economists).
To qualify, the homestead property must have been uninhabitable for at least 30 days and affected owners must file a sworn application for Abatement of Taxes for Homestead Residential Improvements (DR-463) along with supporting documentation to the Property Appraiser.  If approved, the Property Appraiser will issue an official written statement to the Tax Collector, who will calculate and issue the credit. 
WertV's general regulations are further supported by the Wertermittlungsrichtlinie (abbr. WertR, "directive on the determination of value").[21] The WertR provides templates for calculations, tables (e.g., economic depreciation) and guidelines for the consideration of different influences. WertV and WertR are not binding for appraisals for nonofficial use, nonetheless, they should be regarded as best practice or Generally Accepted (German) Valuation Practice (GAVP).

In the course of evaluating a property, an appraiser is expected to be alert and take notice of aspects and characteristics of the property, as well as the surrounding area, that could affect the value. This can include assessing the overall noise levels of the area, proximity to sources of recurring loud disturbances such as an airport or a railroad line, as well as the view offered by the property. Obstructions by neighboring buildings, for instance, could reduce the value of a property.
Other leading appraisal organizations include the National Association of Independent Fee Appraisers and the National Association of Master Appraisers, which were also founding sponsor-members of the Appraisal Foundation.[29] The Massachusetts Board of Real Estate Appraisers (MBREA), founded in 1934, is the only state appraisal association that has been named a sponsor of the Appraisal Foundation.[30] In recent years, the Royal Institution of Chartered Surveyors (RICS) has become highly regarded in the United States, and has formed a collaboration with the Counselors of Real Estate, a division of the National Association of Realtors. RICS, which is headquartered in London, operates on a global scale and awards the designations MRICS and FRICS to Members and Fellows of RICS. The Real Estate Counseling Group of America is a small group of top U.S. appraisers and real estate analysts who have collectively authored a disproportionately large body of appraisal methodology and, the National Association of Real Estate Appraisers (NAREA), founded in 1966, with the goal to elevate the professionalism and success of the Appraisal Industry.
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.
For example, single apartment buildings of a given quality tend to sell at a particular price per apartment. In many of those cases, the sales comparison approach may be more applicable. On the other hand, a multiple-building apartment complex would usually be valued by the income approach, as that would follow how most buyers would value it. As another example, single-family houses are most commonly valued with the greatest weighting to the sales comparison approach. However, if a single-family dwelling is in a neighborhood where all or most of the dwellings are rental units, then some variant of the income approach may be more useful. So the choice of valuation method can change depending upon the circumstances, even if the property being valued does not change much.
