Data is collected on recent sales of properties similar to the subject being valued, called "comparables". Only SOLD properties may be used in an appraisal and determination of a property's value, as they represent amounts actually paid or agreed upon for properties. Sources of comparable data include real estate publications, public records, buyers, sellers, real estate brokers and/or agents, appraisers, and so on. Important details of each comparable sale are described in the appraisal report. Since comparable sales are not identical to the subject property, adjustments may be made for date of sale, location, style, amenities, square footage, site size, etc. The main idea is to simulate the price that would have been paid if each comparable sale were identical to the subject property. If the comparable is superior to the subject in a factor or aspect, then a downward adjustment is needed for that factor.[clarification needed] Likewise, if the comparable is inferior to the subject in an aspect, then an upward adjustment for that aspect is needed.[clarification needed] The adjustment is somewhat subjective and relies on the appraiser's training and experience. From the analysis of the group of adjusted sales prices of the comparable sales, the appraiser selects an indicator of value that is representative of the subject property. It is possible for various appraisers to choose a different indicator of value which ultimately will provide different property value.

Historically, most valuations in Israel were statutory valuations (such as valuations performed for purposes of Betterment Tax, a tax administered on any gains accruing to the property by way of changes to the local planning) as well as valuations performed for purposes of bank lending. Since Israel implemented the International Financial Reporting Standards (IFRS) in 2008, the profession has been engaged in performing valuations for purposes of financial reporting.
Real estate appraisal in Germany is partly codified by law. The federal Baugesetzbuch (abbr. BauGB, "German statutory code on building and construction'") contains guidelines on governing authorities, defines the term market value and refers to continuative rules (chapter 3, articles 192 ff.). Each municipality (city or administrative district) must form a Gutachterausschuss (appraisal committee), consisting of a chairman and honorary members.[18] The committee gathers information on all real estate deals (it is mandatory to send a copy of each notarial purchase contract to the Gutachterausschuss) and includes it in the Kaufpreissammlung (purchase price database). Most committees publish an official real estate market report every two years, in which besides other information on comparables the land value is determined. The committees also perform appraisals on behalf of public authorities.
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.

The Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (FIRREA) demanded all the states to develop systems for licensing and certifying real estate appraisers.[26] To accomplish this, the Appraisal Subcommittee (ASC) was formed within the Federal Financial Institutions Examination Council (FFIEC), with representatives from the various Federal mortgage regulatory agencies.[27] Thus, currently all the real estate appraisers must be state-licensed and certified. But prior to the 1990s, there were no commonly accepted standards either for appraisal quality or for appraiser licensure. In the 1980s, an ad-hoc committee representing various appraisal professional organizations in the United States and Canada met to codify the best practices into what became known as the Uniform Standards of Professional Appraisal Practice (USPAP). The U.S. Savings and Loan Crisis resulted in increased federal regulation via the Financial Institutions Reform, Recovery and Enforcement Act of 1989, which required federal lending regulators to adopt appraisal standards. A nonprofit organization, The Appraisal Foundation (TAF), was formed by the same organizations that had developed USPAP, and the copyright for USPAP was signed over to TAF. Federal oversight of TAF is provided by the Appraisal Subcommittee, made up of representatives of various federal lending regulators. TAF carries out its work through two boards: the Appraisal Standards Board promulgates and updates USPAP; the Appraisal Qualifications Board (AQB) promulgates minimum recommended standards for appraiser certification and licensure. During the 1990s, all of the states adopted USPAP as the governing standards within their states and developed licensure standards which met or exceeded the recommendations of TAF. Also, the various state and federal courts have adopted USPAP for real estate litigation and all of the federally lending regulators adopt USPAP for mortgage finance appraisal.[27]
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.
However, the recent trend of the business tends to be toward the use of a scientific methodology of appraisal which relies on the foundation of quantitative-data,[10] risk, and geographical based approaches.[11][12] Pagourtzi et al. have provided a review on the methods used in the industry by comparison between conventional approaches and advanced ones.[13]

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).[15] 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.
"What is my house worth?"  These real estate appraisers can answer that and much more all over Pinellas County.  Whether it is appraising your home for a property tax appeal if your property taxes are too high, valuing your home for estate work or a divorce or helping you secure a HELOC, a local appraiser is best.  They obviously also appraise new construction homes as well as existing homes, and can do it for a home listing, before or after a sale.  They use the local MLS (Multiple Listing Service) to gather data on sales and listings and use them to professionally tell you what the price per square foot should be for your home and others in your area.  They also can determine if there's any effect on the value of your home from pending foreclosures, REOs, and other "short sales" in Pinellas County.  A licensed and certified appraiser's estimates of value on residential single family homes, condos, townhouses and more are much better than what you'll find when using an AVM (automated valuation model) or a BPO (Broker Price Opinion).  They can do an appraisal for VA, FHA, conventional, jumbo, and Fannie Mae or Freddie Mac purposes, and routinely provide those reports on URAR, drive-by, and 1004 MC (1004 Market Condition) forms as well as others.
