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.

Obstructions by neighboring buildings, for instance, could reduce the value of a property.
A new construction home will require an appraisal if it's being financed. This appraisal will enable the mortgage lender to determine if the property's value is commensurate with the size of the loan being requested. New construction homes can be difficult to appraise. With existing homes, comparable properties are used to establish value. With many new construction homes, comparable properties do not exist, and this can present valuation challenges.
