The sales comparison approach is based primarily on the principle of substitution. This approach assumes a prudent (or rational) individual will pay no more for a property than it would cost to purchase a comparable substitute property. The approach recognizes that a typical buyer will compare asking prices and seek to purchase the property that meets his or her wants and needs for the lowest cost. In developing the sales comparison approach, the appraiser attempts to interpret and measure the actions of parties involved in the marketplace, including buyers, sellers, and investors.
The Property Appraiser Association of Florida (PAAF) has developed a 3rd Homestead Exemption Tax Savings Estimator.  The estimator was developed to help voters determine if they will receive any additional benefit from the proposed 3rd Homestead Exemption (Additional $25,000) on the ballot for the November 6, 2018 General Election.  For additional information please see Understanding the 1st, 2nd, and 3rd Homestead Exemption.
Unlike appraisers, assessors have no federal requirement for certification. In states that mandate certification for assessors, the requirements are usually similar to those for appraisers. For example, the International Association of Assessing Officers (IAAO) offers the Certified Assessment Evaluator (CAE). This designation covers topics that include property valuation for tax purposes, property tax administration, and property tax policy. Applicants are required to have a bachelor's degree prior to obtaining the designation.
"Blockchain will transform the real estate industry. There's no doubt about it, and the earlier entities get on board, the more they stand to gain in terms of security and efficiency," said Tony Franco, CEO of SafeChain. "Starting with something as relatively straightforward as property transfers, blockchain creates a decentralized, near-perfect audit trail that can never be lost or stolen. Eliminating that risk opens the door to completely changing how properties are bought and sold in the U.S., and those changes will ultimately be to the consumer's benefit, as well as the real estate industry's as well."  
Appraisal practice in the United States is regulated by state. The Appraisal Foundation (TAF) is the primary standards body; its Appraisal Standards Board (ASB) promulgates and updates best practices as codified in the Uniform Standards of Professional Appraisal Practice (USPAP), while its Appraisal Qualifications Board (AQB) promulgates minimum standards for appraiser certification and licensing.
In the United States, appraisals are for a certain type of value (e.g., foreclosure value, fair market value, distressed sale value, investment value).
