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.

While the Uniform Standards of Professional Appraisal Practice (USPAP) has always required appraisers to identify the scope of work needed to produce credible results, it became clear in recent years[when?] that appraisers did not fully understand the process for developing this adequately. In formulating the scope of work for a credible appraisal, the concept of a limited versus complete appraisal and the use of the Departure Rule caused confusion to clients, appraisers, and appraisal reviewers. In order to deal with this, USPAP was updated in 2006 with what came to be known as the Scope of Work Project. Following this, USPAP eliminated both the Departure Rule and the concept of a limited appraisal, and a new Scope of Work rule was created. In this, appraisers were to identify six key parts of the appraisal problem at the beginning of each assignment:
While no appraiser is infallible, his or her opinion of the value of your home is informed by rigorous training, numerous tests, several years of on-the-job experience and required continuing education. They are also required to substantiate every finding in their reports that could influence a home’s value. Appraisers and their employers (often appraisal management companies) are heavily regulated. Consequences of issuing deliberately misleading or biased reports can be severe, so appraisers work hard to remain impartial and keep personal value judgments and prejudices out of their work.
