Introduction to Commercial Real Estate Appraisal: The Sales Comparison Approach

What Is The Sale Comparison Approach?

When we consider how to value a commercial real estate property, many factors play a role in determining true market value. There are generally three approaches that an appraiser takes when valuing a property. The Sales Comparison Approach, the Income Approach, and the Cost Approach. One particular method stands out as a cornerstone for determining property values – the Sales Comparison Approach (SCA). This widely used method relies on the principle of comparison to assess the fair market value of a property. In this blog post, we’ll delve into the intricacies of the Sales Comparison Approach, understanding how it works and its crucial role in valuing properties.

What is the Process of the Sales Comparison Approach?

The Sales Comparison Approach, also known as the market data approach or the comparable sales method, is based on the simple concept of comparing similar properties to the one under appraisal. At it’s core, the sales comparison approach is based on the principle of substation that states: a prudent buyer will pay no more for a property than the purchase price of a similar and equally desirable property. The underlying assumption is that a property’s value can be estimated by analyzing the prices of similar properties recently sold in the market. The below steps outline the process of how an appraiser can value a real estate asset using the sales comparison approach:

  1. Selection of Comparable Properties:

The appraiser begins by identifying comparable properties, or “comps,” that share similar characteristics with the subject property. These characteristics may include location, size, age, condition, and features.

  1. Adjustments for Differences:

Since no two properties are identical, adjustments are made to account for differences between the subject property and the chosen comparables. For instance, if the subject property has superior parking, the appraiser might add a certain amount to reflect this difference.

  1. Data Analysis:

The appraiser carefully analyzes the sales data of the comparable properties, considering factors such as the date of sale, financing terms, and any unique conditions that might have influenced the transaction.

  1. Reconciliation of Values:

After making adjustments to the comparable properties, the appraiser reconciles the values to arrive at a final estimate of the subject property’s market value. This involves weighing the significance of each comparable and reaching a well-informed conclusion.

Advantages of the Sales Comparison Approach:

  1. Ubiquity:

The Sales Comparison Approach is widely used because it reflects the way buyers and sellers typically make decisions in the real estate market. People often look at recent sales of similar properties to gauge the value of a prospective purchase or sale.

  1. Adaptability:

This approach is adaptable to various property types, including industrial, retail, multifamily, and specialty properties such as churches and marinas, and vacant land. Whether appraising a suburban home or a downtown office building, the Sales Comparison Approach can be applied with suitable adjustments.

  1. Market-Driven:

By relying on recent market transactions, the Sales Comparison Approach reflects the current dynamics of the real estate market. This makes it particularly valuable in areas where market conditions are rapidly changing.

The Challenges and Considerations of the Sales Comparison Approach

No approach to value is perfect, and the sales comparison approach has its own specific advantages and disadvantages when valuing a property. Two drawbacks of the sales comparison approach may be the inability to find comparable sales and that adjustments are based on the individual appraiser’s experience and subjective opinion.

  1. Availability of Comparable Sales:

In some cases, finding truly comparable sales can be challenging, especially in unique or specialized properties. Appraisers must use their judgment to make reasonable adjustments in such situations.

  1. Subjectivity in Adjustments:

The process involves subjective judgments in adjusting for differences between properties. Appraisers need to rely on their experience and expertise to make accurate adjustments.

What is the Importance of the Sales Comparison Approach?

The Sales Comparison Approach remains a fundamental tool in the real estate appraiser’s toolkit. By drawing upon the market’s own data and dynamics, this method provides a robust and transparent way to estimate the fair market value of a property. As with any appraisal method, the key lies in the appraiser’s ability to select appropriate comparables, make accurate adjustments, and analyze the data effectively. The Sales Comparison Approach, when executed diligently, not only enhances the accuracy of property valuations but also contributes to the overall transparency and reliability of the real estate market.
