What are the types of AVMs?

The choice of AVM type depends on the available data, market conditions, and specific valuation requirements. Different AVMs may be more suitable for various property types, regions, or purposes, and the accuracy of the valuation may vary depending on the chosen AVM approach. There are several types of AVMs, each employing different methodologies and data sources.

Hedonic AVMs
• Price Index AVMs
• Tax assessors AVMs
• Comparative AVMs
• Hybrid AVMs

What are Hedonic models?

Hedonic models, also known as hedonic regression models, are statistical models used in real estate valuation to analyze the relationship between the characteristics of a property and its market value. These models assume a property’s value is derived from its various attributes or characteristics.

In a hedonic model, the value of a property is expressed as a function of its observable attributes, such as location, size, number of bedrooms and bathrooms, amenities, condition, and other relevant factors. The model quantifies each attribute’s contribution to the property’s overall value.

The key concept behind hedonic models is that buyers and sellers in the real estate market consider the different attributes of a property and are willing to pay more or less based on their preferences and perceived value. By analyzing a large property sales dataset, the hedonic model estimates the value of each attribute and how it influences the overall market value.

Hedonic models are typically developed using regression analysis, where historical sales data is used to identify the relationships between property attributes and sale prices. The model estimates the impact of each attribute by calculating coefficients that represent the marginal contribution of that attribute to the property’s value.

These models are widely used in Automated Valuation Models (AVMs) to estimate property values. By incorporating a range of attributes and their corresponding values, hedonic models provide a more comprehensive and detailed approach to property valuation, accounting for the factors that buyers and sellers consider when determining the value of a property.


• Can be very accurate in predicting property values.

• Can be used to analyze a wide variety of property characteristics.


• Can be complex and time-consuming to develop.

• Requires a large amount of data.

What are Tax assessor models?

Tax assessor models, also known as assessment models or mass appraisal models, are statistical models used by tax assessors or government agencies to determine property values for the purpose of property taxation. These models aim to estimate the fair market value of properties within a specific jurisdiction.

Tax assessor models differ from traditional appraisal methods, focusing on assessing many properties simultaneously rather than conducting individual appraisals for each property. They are designed to handle the assessment process efficiently and consistently across various properties.

These models typically use a combination of statistical techniques, property data, and market information to estimate property values. The data used in tax assessor models can include property characteristics, such as size, location, construction type, number of rooms, and other relevant factors. They also incorporate sales data and valuation ratios to establish a baseline for property values.


• Simple and easy to use.

• Based on historical data, so can be relatively accurate.


• May not be as accurate as hedonic models.

• May not take into account recent market trends.

What are Price index models?

Price index models, also called index-based models, are statistical models used to estimate property values based on changes in price indices. These models rely on the relationship between property prices and general market trends captured by various price indices.

Price index models assume that property values are influenced by broader market movements rather than individual property characteristics. These models track changes in price indices over time and apply these trends to estimate the current value of a property.

The key component of price index models is the selection of an appropriate price index. Commonly used indices include housing price indices, consumer price indices, or regional-specific indices that capture local market trends. These indices serve as benchmarks for property value fluctuations.

To estimate the value of a specific property using a price index model, the model analyzes historical data on the relationship between the chosen price index and property prices. By identifying patterns and correlations, the model determines how price index changes correspond to property value changes.

Once the relationship between the price index and property values is established, the model applies the latest available price index data to estimate the property’s current value. The estimated value is derived by multiplying the property’s previous value by the percentage change indicated by the price index.


• Simple and easy to use.

• Based on recent sales data, so can be relatively accurate.


• May not be as accurate as hedonic models.

• May not take into account all property characteristics.

In conclusion, Automated Valuation Models (AVMs) have become a valuable tool for real estate professionals, offering numerous benefits in property valuation. AVMs provide speed, efficiency, and cost-effectiveness by automating the valuation process, saving time and resources. They offer objective and consistent estimates, leveraging advanced algorithms and large databases of property information.

It’s important to note that there are different types of AVMs, each with its own advantages and disadvantages. Hedonic models offer great value-prediction accuracy and can analyze a wide variety of property characteristics. In contrast, price index models rely on price indices to estimate property values and are simple to use. In addition to, models like tax assessor models with their simplicity in use and accuracy when it depends on historical data.

Choosing the best type of AVM for a particular situation depends on the user’s specific needs. Factors such as property type, location, market conditions, and valuation requirements should be considered.
