Automated valuation models (AVMs) are growing in acceptance. These rely on statistical models such as multiple regression analysis, machine learning algorithms or geographic information systems (GIS).[17] While AVMs can be quite accurate, particularly when used in a very homogeneous area, there is also evidence that AVMs are not accurate in other instances such as when they are used in rural areas, or when the appraised property does not conform well to the neighborhood.

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.
The Florida Constitution and Florida Statutes §119 and §286 safeguard every Floridian’s right of access to government meetings and public records. In Florida, disclosure is the standard, unless the Legislature allows an exemption or the records are otherwise confidential. Every citizen has the right to obtain public records that are not exempted or confidential. Citizens and the media can easily request public records from Pinellas County government. The requester is responsible for any cost of providing the documentation, which includes staff time, cost of copies and other costs that are associated with the request.
