They have all kinds of methods for pricing a house, but the most common among them is the Sales Comparison Approach (SCA), where you find out how much a similar home has sold for. Knowing how this works can help you make wiser decisions in buying a home, investing in real estate, or getting an assessment.

The sales comparison approach in real estate is what this article focuses on, and we will examine how it is applied, its advantages and disadvantages, and how it measures up with other property valuation approaches.

Understanding The Sales Comparison Approach in Real Estate

The sales comparison method is primarily founded on the substitution idea. This idea says that an informed buyer will not pay more for a property than it would cost to buy an identical value-in-use property. Appraisers can also deploy comparable sales to get value for the property.

The approach involves finding comparable properties, examining how they compare and differ with the subject property, and making changes to account for these variations. The adjusted cost of the comparable offers a range of values that the assessor uses to get the final figure of worth.

Key Steps in the Sales Comparison Approach

Market Research: Start with market research, such as finding the recent sales, listings, and pending sales of similar properties to the subject property. And it is the process of gathering data on properties sharing common location, scale, design and use.
Confirmation of Information: Ensure the news you’ve found is real. This means being verified by a buyer, seller, or broker of the sale price, conditions of sale, and terms.
Comparable Selection: The appraiser selects homes most similar to the subject. Physical features, physical condition, location, and market conditions are considered when deciding what comparable properties to utilize. Ideally, the comparable property would share the same highest and best use with the subject.
Adjustments for Differences: Adjustments to the comparable sale prices are applied to compensate for differences in attributes like location, size, condition, and amenities. These adjustments can be expressed in dollar amounts or percentages.
Reconciliation: The adjusted sale prices of the comparable are analyzed to determine a range of values. The appraiser reconciles these values into a single opinion of value, considering the quality and quantity of the data.

Importance of Sales Comparison Approach

The sales comparison method is valuable in itself as it actually reflects what buyers and sellers actually do in the marketplace. It employs data that exists within the market, thus making it a valid measure of value. This approach can be especially effective in occupied markets with a large number of similar sales.

For residential properties, the sales comparison method can be the most appropriate. It is also frequently used for commercial and industrial buildings, if there is enough sales data. However, the strategy may be less effective in impoverished markets or for unusual homes with few comparable sales.

How the Sales Comparison Approach Works

Here’s a simple step-by-step look at how the sales comparison approach is used in real estate:

Find Similar Properties
Professionals look for three to five homes that are close by and similar in size, features, and condition. These homes should have sold recently, usually in the past three to six months.
Make Adjustments for Differences
Even homes that look alike often have some differences. For example:

If the subject home contains an extra bathroom compared with a similar home sold, then the price of the bathroom would be added to the price of the sold home.

If the other home has been equipped with a very good kitchen compared to the other one or a bigger yard, then the price will go down a little.

Adjust the Prices
Each sale price is changed based on these differences so that it's as if those homes were exactly like the one being valued.
Figure Out the Value
After adjustments, the professional compares the new prices of similar homes and comes up with an average or most likely value for the property.

Challenges and Best Practices.

While the sales comparison method is a successful instrument, it is not without disadvantages. Appraisers may come into situations in which there is a paucity of recent sales data or the subject property is unique. In these situations, appraisers must use their judgment and creativity to produce trustworthy results.

Some common issues are:

Insufficient Market Data: Finding similar homes in markets with little sales activity could prove tricky. Appraisers may need to broaden their search regionally or evaluate older transactions, making adjustments that are needed over time.
Dissimilar Alternatives: When the subject property has unique features, it might be difficult to identify comparable transactions. Appraisers must carefully consider these variations.
Unsupported Adjustments: Any adjustments must be based on market facts.

Adjustments that are not demonstrated or made unilaterally could undermine the appraisal's trustworthiness.

To address these concerns, evaluators should:

Conduct thorough market analysis to determine the most appropriate equivalents.
Use qualitative as well as quantitative evaluation to argue for adjustments.
Their reasons and methods should be clearly documented in the evaluation report.

Example of the Sales Comparison Approach

Let’s say you're trying to value a 3-bedroom, 2-bathroom home with 1,800 square feet.

You find these three recently sold homes:

Home A: Sold for $360,000 — same size and layout, but has a bigger backyard.
Home B: Sold for $355,000 — similar features, but with a new kitchen.
Home C: Sold for $370,000 — very similar, but on a quieter street.

You adjust these prices by adding or subtracting based on the differences. For example, if Home B’s new kitchen adds $5,000 in value, and your home doesn't have it, you subtract that from its sale price. After all the changes, you average the adjusted prices. Let’s say that comes out to $362,000—this is your estimated value.

How Does It Compare to Other Methods?

Cost Approach.
This is an estimate of what it would cost to build an identical home today, excluding wear and tear. It's often used for new or unique homes.
Income Approach.
This approach considers how much money a property may generate (through things like rent) and is often used for rental or company properties.

In Comparison:

Apply the sales comparison method to typical residences.
Use the cost technique while building a custom or new house.
For rental properties or commercial structures, apply the income method.

The sales comparison approach in real estate is one of the most straightforward and trusted ways to determine a property's value. Examining what comparable homes in the area have sold for recently and adjusting for differences helps buyers, sellers, and appraisers make better, more informed decisions. This is usually more effective in markets with more recent data available, but it is still a practical method at hand to value residential and even some commercial properties. Understanding how this approach works allows you to make confident decisions in your buying, selling, or investing process.
