What Do Appraisers Use For Comparables? Appraisers rely on comparable sales data, or “comps,” to determine the fair market value of a property, and this information is crucial for making sound real estate decisions. At COMPARE.EDU.VN, we understand the importance of accurate property valuation, so let’s dive into the specifics of how appraisers choose and use comps, ensuring you have a clear understanding of the appraisal process and can make informed decisions; understanding these factors is vital for buyers, sellers, and real estate professionals alike, contributing to more transparent and equitable property transactions. To gain comprehensive insights into property valuation, explore related topics like market analysis, property assessment, and real estate appraisal methods.
1. Understanding Comparables in Real Estate Appraisal
1.1. Defining Comparables: What Makes a Property a “Comp”?
In real estate appraisal, a comparable property, often called a “comp,” is a recently sold property that shares similar characteristics with the subject property being appraised. These characteristics include location, size, style, age, condition, and amenities. Appraisers use comps to estimate the market value of the subject property by analyzing the prices at which similar properties have recently sold. The goal is to find properties that are as alike as possible to the subject property, making any necessary adjustments for differences to arrive at an accurate valuation.
1.2. The Role of Comparables in Determining Property Value
Comps play a vital role in the appraisal process. They provide tangible evidence of what buyers are willing to pay for properties with similar features in the same market. By analyzing several comparable sales, appraisers can establish a range of values for the subject property. This range is then refined by making adjustments for any differences between the comps and the subject property. For example, if a comp has an extra bathroom or a larger lot, the appraiser will adjust the comp’s sale price downward to reflect the value of those features. Conversely, if the subject property has features that the comps lack, the appraiser will adjust the comp’s sale price upward.
1.3. Key Characteristics Appraisers Look For in Comps
Appraisers consider a variety of characteristics when selecting comparable properties. These characteristics can be broadly categorized into:
- Location: Comps should be located in the same neighborhood or a similar market area as the subject property.
- Physical Characteristics: Size, style, age, condition, and construction quality should be similar between the comps and the subject property.
- Features and Amenities: The number of bedrooms and bathrooms, the presence of a garage or swimming pool, and other amenities should be comparable.
- Sale Date: Comps should have been sold recently, ideally within the past few months, to reflect current market conditions.
- Sale Conditions: The sale should be an arm’s-length transaction, meaning it was conducted between unrelated parties under normal market conditions.
1.4. Why Accurate Comps are Crucial for a Fair Appraisal
Accurate comps are essential for a fair and reliable appraisal. If the comps are not truly comparable or if the appraiser fails to make appropriate adjustments, the resulting valuation may be inaccurate. This can have significant consequences for both buyers and sellers. An inflated appraisal can lead to overpaying for a property, while an undervalued appraisal can result in a lost sale or missed opportunity. Therefore, it is crucial for appraisers to use sound judgment and follow established guidelines when selecting and analyzing comps.

2. The Appraiser’s Toolkit: Resources and Methods
2.1. Multiple Listing Service (MLS) and Other Real Estate Databases
The Multiple Listing Service (MLS) is a comprehensive database of properties listed for sale, as well as recently sold properties. It is the primary tool used by appraisers to find comparable sales data. The MLS contains detailed information about each property, including its address, size, features, sale price, and sale date. Appraisers can search the MLS using specific criteria to identify properties that are similar to the subject property.
In addition to the MLS, appraisers may also use other real estate databases, such as public records databases and commercial data providers. These databases can provide additional information about property sales, such as tax assessments, ownership history, and property characteristics.
2.2. Public Records and Government Data Sources
Public records, such as county assessor records and deeds, can provide valuable information about property ownership, tax assessments, and property characteristics. Appraisers often use these records to verify information obtained from the MLS and other sources. They may also use government data sources, such as census data and economic reports, to analyze market trends and economic conditions that may affect property values.
2.3. Appraisal Software and Data Analysis Tools
Appraisers use specialized software to manage and analyze the data they collect. This software can help them organize comps, make adjustments, and generate appraisal reports. Data analysis tools, such as statistical software and mapping software, can help appraisers identify patterns and trends in the market. These tools can also help them assess the impact of various factors on property values, such as location, amenities, and economic conditions.
2.4. On-Site Property Inspections: Gathering Firsthand Data
An on-site property inspection is an essential part of the appraisal process. During the inspection, the appraiser visually examines the subject property to assess its condition, features, and amenities. The appraiser takes measurements and photographs of the property to document its physical characteristics. They also look for any factors that may affect its value, such as deferred maintenance, renovations, or environmental hazards. The data gathered during the on-site inspection is used to verify information obtained from other sources and to make informed adjustments to the comps.

2.5. The Importance of Local Market Knowledge
Local market knowledge is crucial for appraisers. They must be familiar with the specific characteristics of the local market, such as neighborhood trends, zoning regulations, and economic conditions. This knowledge helps them identify appropriate comps, make accurate adjustments, and interpret market data effectively. Appraisers often develop their local market knowledge through experience, networking with other real estate professionals, and ongoing education.
3. Key Factors Appraisers Consider When Selecting Comps
3.1. Location, Location, Location: Neighborhood and Proximity
Location is one of the most important factors that appraisers consider when selecting comps. Comps should be located in the same neighborhood or a similar market area as the subject property. The closer the comps are to the subject property, the more reliable they are likely to be. Appraisers typically prefer to use comps that are within one mile of the subject property, but this may vary depending on the density of the area and the availability of comparable sales.
3.2. Similarity in Property Characteristics: Size, Style, and Age
Comps should be similar to the subject property in terms of size, style, and age. Appraisers typically look for comps that are within 20% of the size of the subject property. The style of the property should also be similar, such as a single-family home, a townhouse, or a condominium. The age of the property should be comparable as well, as newer homes may command higher prices than older homes.
3.3. Condition and Quality of Construction: Accounting for Upgrades and Repairs
The condition and quality of construction of the comps should be similar to the subject property. Appraisers consider factors such as the overall condition of the property, the quality of the materials used in construction, and the presence of any upgrades or repairs. If a comp has been recently renovated or upgraded, the appraiser will adjust its sale price accordingly.
3.4. Date of Sale: Using Recent Sales Data to Reflect Market Trends
The date of sale is another important factor to consider. Comps should have been sold recently, ideally within the past few months, to reflect current market conditions. Appraisers typically use the most recent sales data available, but they may also consider older sales data if there are not enough recent sales to provide a reliable basis for comparison. The strongest indicators of current value are those comps that have closed within the past 90 days. Pending sales and listings are only used on the appraisal report to show what the current market is doing; appraisers do not consider these comps in their final opinion of value.
3.5. Lot Size and Features: Adjusting for Differences in Land Value
The lot size and features of the comps should be similar to the subject property. Appraisers consider factors such as the size of the lot, its shape, its topography, and its access to utilities. They also consider the presence of any features that may affect its value, such as a swimming pool, a garage, or a view. The appraiser must also consider the lot size and lot utility in the valuation. If the subject and all comps have flat usable lots, the appraiser will adjust for large variances in lot size. In areas where lots are sloped, appraisers will estimate a lot’s usable area or “utility” and adjust accordingly. The important thing to remember is that a 40,000 square foot sloped lot will often not have any more value than a 10,000 square foot flat lot.
4. Making Adjustments: Quantifying Differences Between Properties
4.1. Understanding the Need for Adjustments
Even when appraisers find comps that are similar to the subject property, there are likely to be some differences between them. These differences may include variations in size, condition, features, or location. To account for these differences, appraisers make adjustments to the sale prices of the comps. The goal of these adjustments is to estimate what the comps would have sold for if they were identical to the subject property.
4.2. Common Adjustment Factors: Size, Condition, and Features
Appraisers use a variety of factors to make adjustments to the sale prices of the comps. Some of the most common adjustment factors include:
- Size: Adjustments are made for differences in the square footage of the properties.
- Condition: Adjustments are made for differences in the condition of the properties, such as the presence of deferred maintenance or recent renovations.
- Features: Adjustments are made for differences in the features of the properties, such as the number of bedrooms and bathrooms, the presence of a garage or swimming pool, and the quality of the finishes.
4.3. Location Adjustments: Accounting for Neighborhood Differences
Location adjustments are made to account for differences in the desirability of the neighborhoods where the comps and the subject property are located. These adjustments may be based on factors such as school quality, crime rates, and access to amenities. If the subject is on a busy street or abuts a school, freeway, railroad, industrial area, cemetery, etc., the appraiser must include at least one comparable in the report with a similar location influence. This is necessary to determine if an adjustment is required for the adverse influence.
4.4. Market Condition Adjustments: Reflecting Changes Over Time
Market condition adjustments are made to reflect changes in market conditions that may have occurred between the sale date of the comps and the date of the appraisal. These adjustments may be based on factors such as changes in interest rates, unemployment rates, and housing inventory levels.
4.5. How Appraisers Determine the Size of Adjustments
Appraisers use a variety of methods to determine the size of the adjustments they make to the sale prices of the comps. These methods may include:
- Paired Sales Analysis: This method involves comparing the sale prices of two similar properties that differ in only one characteristic. The difference in sale prices is then used as the basis for the adjustment.
- Cost Approach: This method involves estimating the cost of replacing the feature that is different between the properties. This cost is then used as the basis for the adjustment.
- Market Data: This method involves analyzing market data to determine the typical value of the feature that is different between the properties. This value is then used as the basis for the adjustment.
5. Common Challenges in Finding and Using Comps
5.1. Limited Availability of Truly Comparable Sales
One of the biggest challenges that appraisers face is the limited availability of truly comparable sales. In some markets, there may be very few properties that are similar to the subject property. This can make it difficult to find comps that are reliable and accurate.
5.2. Dealing with Unique or Custom Properties
Unique or custom properties can be particularly challenging to appraise because there may be very few comparable sales available. In these cases, appraisers may need to rely on other appraisal methods, such as the cost approach or the income approach, to estimate the value of the property.
5.3. Market Fluctuations and Rapidly Changing Conditions
Market fluctuations and rapidly changing conditions can make it difficult to find comps that accurately reflect current market values. In a rapidly rising market, comps that sold even a few months ago may no longer be representative of current market conditions. Appraisers need to be aware of these fluctuations and make appropriate adjustments to the sale prices of the comps.
5.4. Data Accuracy and Verification Issues
Data accuracy and verification issues can also pose challenges for appraisers. The information contained in the MLS and other real estate databases is not always accurate or complete. Appraisers need to verify the information they obtain from these sources and correct any errors or omissions.
5.5. Overcoming Appraisal Bias and Maintaining Objectivity
Appraisal bias can be a significant concern in the appraisal process. Appraisers need to be objective and unbiased in their analysis and avoid any influences that may lead them to inflate or deflate the value of the property. To maintain objectivity, appraisers should follow established appraisal guidelines and standards and avoid any conflicts of interest.
6. Guidelines for Realtors: How to Help the Appraisal Process
6.1. Understanding Appraisal Guidelines and Standards
Realtors can play a valuable role in helping the appraisal process by understanding appraisal guidelines and standards. By familiarizing themselves with these guidelines, realtors can provide appraisers with relevant information and avoid submitting comps that are unlikely to be used.
6.2. Providing Accurate and Relevant Information to Appraisers
Realtors should provide appraisers with accurate and relevant information about the subject property and the local market. This information may include details about recent renovations, upgrades, and sales trends. Realtors should also be transparent about any potential issues that may affect the value of the property, such as environmental hazards or zoning restrictions.
6.3. Selecting Appropriate Comps: Focus on Similarity and Proximity
Realtors can assist appraisers by selecting appropriate comps. When selecting comps, realtors should focus on similarity and proximity. The comps should be similar to the subject property in terms of size, style, age, condition, and features. They should also be located in the same neighborhood or a similar market area as the subject property. Comps should ideally be within 20% of the size of the subject property (unless no other comps are available). For example, appraisers usually cannot use a 1,300 sf comp for a 1,000 sf subject property. Likewise, appraisers cannot use a 700 sf comp for a 1,000 sf property. Appraisers also cannot simply employ a “price per square foot analysis” like some agents and homeowners often do; appraisers are required to correlate to similar-sized homes. Comps should ideally be within one mile of the subject property and not over any major barriers like a freeway, a river, or railroad tracks. Comps need to be in the same city as the subject property in most cases, even if a comp in another city is less than a block from the subject property.
6.4. Avoiding Inflated or Unrealistic Comps
Realtors should avoid submitting inflated or unrealistic comps to appraisers. These comps are unlikely to be used and may damage the realtor’s credibility. Instead, realtors should focus on providing appraisers with comps that are well-supported by market data and reflect the true value of the property. Valid comps need to “bracket” the appraised value. Hence, at least one comp needs to be priced higher than the appraised value, and one should be priced lower. Additionally, the appraiser must “bracket” each amenity of the home with the comps. For example, the appraiser must include homes that are larger and smaller than the subject to “bracket” the size of the home.
6.5. Communicating Effectively with Appraisers
Realtors should communicate effectively with appraisers and be responsive to their requests for information. They should also be respectful of the appraiser’s professional judgment and avoid pressuring them to inflate the value of the property.
7. Homeowner’s Guide to Understanding Comparables
7.1. How Comps Affect Your Home’s Value
As a homeowner, understanding how comps affect your home’s value is essential whether you’re planning to sell, refinance, or simply want to know your property’s worth. Comparables, or “comps,” are recently sold properties similar to yours in terms of location, size, style, age, condition, and features. Appraisers use these comps to determine the fair market value of your home. The higher the sale prices of comparable properties, the higher your home’s value is likely to be. Conversely, if comparable properties have sold for lower prices, your home’s value may be lower as well.
7.2. Researching Comps: Where to Find Sales Data
If you want to get an idea of your home’s value, you can research comps yourself. There are several sources of sales data that you can use, including:
- Online Real Estate Portals: Websites like Zillow, Redfin, and Realtor.com provide information on recently sold properties in your area.
- County Assessor Records: You can access property records, including sales data, through your county assessor’s office.
- Real Estate Agents: Local real estate agents can provide you with information on comparable sales in your area.
7.3. Evaluating Comps: What to Look For
When evaluating comps, focus on properties that are as similar to your home as possible. Consider the following factors:
- Location: Look for properties in your neighborhood or a similar market area.
- Size: Compare the square footage of the properties.
- Style: Look for properties with the same architectural style as your home.
- Age: Compare the age of the properties.
- Condition: Consider the overall condition of the properties.
- Features: Compare the number of bedrooms and bathrooms, the presence of a garage or swimming pool, and other amenities.
7.4. Understanding Adjustments: Why Comps Aren’t Always Identical
Even when you find comps that are similar to your home, there are likely to be some differences between them. Appraisers make adjustments to the sale prices of the comps to account for these differences. For example, if a comp has an extra bathroom, the appraiser will adjust its sale price downward to reflect the value of that feature.
7.5. Preparing for an Appraisal: Tips for Homeowners
If you are planning to have your home appraised, there are several things you can do to prepare:
- Clean and Declutter: Make sure your home is clean and well-maintained.
- Make Necessary Repairs: Address any deferred maintenance issues.
- Highlight Upgrades: Provide the appraiser with information on any recent renovations or upgrades.
- Provide Comps: If you have researched comps yourself, provide them to the appraiser.
- Be Present During the Inspection: Be available to answer any questions the appraiser may have.
8. Appraisals in a Changing Market: Adapting to New Realities
8.1. The Impact of Economic Factors on Comparables
Economic factors, such as interest rates, unemployment rates, and inflation, can have a significant impact on comparables and property values. In a rising interest rate environment, for example, borrowing costs increase, which can dampen demand for housing and put downward pressure on prices. Conversely, in a low interest rate environment, borrowing costs decrease, which can stimulate demand for housing and drive up prices. Similarly, high unemployment rates can reduce demand for housing, while low unemployment rates can increase demand. Appraisers need to be aware of these economic factors and adjust their analysis accordingly.
8.2. Adjusting for Foreclosures and Short Sales
Foreclosures and short sales can distort market values and make it difficult to find reliable comps. These properties are often sold at a discount, which can skew the data. Appraisers need to be careful when using foreclosures and short sales as comps and make appropriate adjustments to account for their distressed nature.
8.3. The Role of Technology in Modern Appraisal
Technology is playing an increasingly important role in modern appraisal. Appraisers now have access to a wide range of online tools and databases that can help them find comps, analyze market data, and generate appraisal reports. Automated valuation models (AVMs) are also becoming more sophisticated and are being used to supplement traditional appraisal methods.
8.4. Maintaining Accuracy in a Fast-Paced Market
In a fast-paced market, it can be challenging to maintain accuracy and keep up with rapidly changing conditions. Appraisers need to be proactive in monitoring market trends and adjusting their analysis accordingly. They also need to be vigilant about verifying data and avoiding reliance on outdated information.
8.5. The Future of Comparables in Real Estate Valuation
The future of comparables in real estate valuation is likely to be shaped by several factors, including technological advancements, changing market conditions, and evolving regulatory requirements. As technology continues to advance, appraisers will have access to more sophisticated tools and data sources. This will enable them to perform more accurate and efficient appraisals. However, the human element of appraisal will remain critical. Appraisers will still need to exercise sound judgment and apply their local market knowledge to arrive at credible valuations.
9. Case Studies: Real-Life Examples of Comp Analysis
9.1. Case Study 1: Appraising a Single-Family Home in a Suburban Neighborhood
In this case study, we examine the appraisal of a single-family home in a suburban neighborhood. The appraiser identified three comparable sales in the same neighborhood that had sold within the past three months. The comps were similar to the subject property in terms of size, style, age, and condition. However, there were some differences in features, such as the presence of a swimming pool and a finished basement. The appraiser made adjustments to the sale prices of the comps to account for these differences and arrived at an estimated value for the subject property.
9.2. Case Study 2: Appraising a Condominium in an Urban Setting
In this case study, we examine the appraisal of a condominium in an urban setting. The appraiser faced challenges in finding comps due to the limited availability of similar properties in the immediate area. The appraiser expanded the search area and identified three comparable sales in nearby buildings. The comps were similar to the subject property in terms of size, layout, and amenities. However, there were differences in the views and the level of building amenities. The appraiser made adjustments to the sale prices of the comps to account for these differences and arrived at an estimated value for the subject property. The appraiser should ideally include comps from inside and outside of the complex. If either are missing, underwriters often call for appraisal reviews.
9.3. Case Study 3: Appraising a Rural Property with Acreage
In this case study, we examine the appraisal of a rural property with acreage. The appraiser faced challenges in finding comps due to the unique characteristics of the property, such as its large lot size, its rural location, and its agricultural zoning. The appraiser expanded the search area and identified three comparable sales of similar rural properties with acreage. The comps were similar to the subject property in terms of lot size, land use, and access to utilities. However, there were differences in the quality of the homes and the presence of outbuildings. The appraiser made adjustments to the sale prices of the comps to account for these differences and arrived at an estimated value for the subject property.
9.4. Key Takeaways from the Case Studies
These case studies illustrate the importance of finding appropriate comps, making accurate adjustments, and applying sound judgment in the appraisal process. They also highlight the challenges that appraisers may face in different types of markets and with different types of properties.
10. Ensuring Appraisal Accuracy and Fairness
10.1. The Role of Appraisal Regulations and Standards
Appraisal regulations and standards play a crucial role in ensuring appraisal accuracy and fairness. These regulations and standards, such as the Uniform Standards of Professional Appraisal Practice (USPAP), provide guidelines for appraisers to follow in their analysis and reporting. They also help to prevent fraud and bias in the appraisal process.
10.2. Understanding the Uniform Standards of Professional Appraisal Practice (USPAP)
The Uniform Standards of Professional Appraisal Practice (USPAP) is the generally recognized ethical and performance standards for appraisers in the United States. USPAP sets forth requirements for appraisers in areas such as competency, independence, and objectivity. It also provides guidelines for developing and reporting appraisals.
10.3. What to Do if You Suspect an Inaccurate Appraisal
If you suspect an inaccurate appraisal, there are several steps you can take:
- Review the Appraisal Report: Carefully review the appraisal report to identify any errors or omissions.
- Contact the Appraiser: Contact the appraiser and discuss your concerns.
- Obtain a Second Opinion: Obtain a second appraisal from a different appraiser.
- File a Complaint: File a complaint with the state appraisal board.
10.4. The Importance of Independent Appraisals
Independent appraisals are essential for ensuring fairness and objectivity in the appraisal process. An independent appraiser is one who has no financial interest in the transaction and is not influenced by any of the parties involved.
10.5. Promoting Transparency and Trust in the Appraisal Process
Promoting transparency and trust in the appraisal process is crucial for maintaining confidence in the real estate market. This can be achieved through clear communication, ethical conduct, and adherence to established regulations and standards.
