Automated valuation models estimate real estate value using a mathematical model and a database of known property values. They use repeat sales index and hedonic models to determine value. Advantages include saving time and resources, but drawbacks include less accuracy for new builds and not considering all variables.
An automated valuation model is a service that estimates the value of real estate. The estimation is done almost entirely on the computer. The computer comes up with an estimate of the value using a mathematical model and a database of known property values. Other sources of data can also be used, such as the opinions of appraisers who have appraised the home in the past and information on the value of work done on the home. The automated valuation model is used on Wall Street and by appraisers and lenders to decide both how much a piece of real estate is worth and how much to lend against that property.
The automated valuation model uses two methods to obtain an estimate. First, access a repeat sales index. This index measures price changes over the years as property and others like it have been sold and refinanced.
The automated appraisal model also uses a hedonic model to determine the current absolute value of the home. A hedonic model finds the value of something by breaking it into parts and assigning each part a value. All values are then added together. In real estate, property valuation is based on variables such as the number of bedrooms, square footage and the age of the building.
Real estate experts have pointed out several advantages of the automated valuation model over lower-tech valuation methods. The automated assessment model saves time, money and resources as it can be done entirely online. It is also more difficult to commit real estate fraud using this method because fewer people are involved. Automated appraisal templates are accessible to the average homeowner. Some companies offer automated appraisal modeling services to Internet homeowners.
As with any technology, automated pricing models also have drawbacks. The computer can only make an educated guess about the value of the property. Some variables are not taken into consideration. For example, the condition of the property is not considered. This can lead to a higher appraised value for the property than is justified.
The automated evaluation model is also less accurate when evaluating a new build. New construction is more difficult to value because there is less data to compare it against. The model can only use similar homes in that area instead of drawing on data for the specific property in question.
