When it comes to determining the value of a property, two common methods are used: Comparative Market Analysis (CMA) and Appraisal.

While both methods aim to estimate the value of a property, they differ in their approach, scope, and purpose.

Comparative Market Analysis (CMA)

A Comparative Market Analysis (CMA) is a report prepared by a licensed real estate agent or broker to estimate the value of a property. The report compares the subject property to similar properties that have recently sold in the same area, known as “comps.” The CMA takes into account various factors, including:

• Location
• Size
• Age
• Style
• Condition
• Features (e.g., number of bedrooms, bathrooms, fireplaces)
• Recent sales data

The CMA provides an estimated value range for the subject property, which can help sellers set a competitive asking price and buyers make informed offers.

Appraisal

An Appraisal is a more formal and detailed process conducted by a licensed and certified appraiser. The appraiser visits the property, inspects its condition, and gathers data on its features and amenities. The appraisal report includes:

• An estimate of the property’s value based on its physical characteristics and market conditions
• A detailed description of the property’s condition, including any defects or needed repairs
• A list of comparable sales data used to support the estimated value
• An analysis of market trends and conditions

Appraisers are trained to provide an unbiased opinion of value, making them a reliable source for lenders, buyers, and sellers.

Key Differences

• Purpose: A CMA is used to estimate the value of a property for listing or buying purposes, while an Appraisal is used to determine the value of a property for lending or insurance purposes.
• Scope: A CMA typically focuses on recent sales data and market trends, while an Appraisal includes a detailed physical inspection of the property and an analysis of its condition.
• Expertise: A CMA is prepared by a licensed real estate agent or broker, while an Appraisal is conducted by a licensed and certified appraiser.
• Accuracy: Appraisals are generally considered more accurate than CMAs, as they are based on a detailed physical inspection and analysis of the property’s condition.
• Cost: CMAs are often provided free or at a low cost by real estate agents, while Appraisals can be more expensive, typically ranging from $300 to $1,000 or more, depending on the location and complexity of the appraisal.

In summary, while both CMAs and Appraisals aim to estimate the value of a property, they differ in their approach, scope, and purpose. A CMA is a useful tool for real estate agents and clients, while an Appraisal is a more formal and detailed process used for lending and insurance purposes.

A Comparative Market Analysis (CMA) in real estate is a report that estimates the value of a property by comparing it to similar properties that have recently sold or are currently listed for sale in the same area. The CMA is typically prepared by a licensed real estate agent or broker and is used to help sellers set a listing price for their property and to help buyers make informed offers.

A CMA typically includes the following information:

• A list of comparable properties (comps) that have recently sold or are currently listed for sale in the same area
• The sale prices and other relevant details of the comps, such as square footage, number of bedrooms and bathrooms, and lot size
• An analysis of the similarities and differences between the subject property and the comps
• An estimated value of the subject property based on the analysis of the comps

The CMA is a useful tool for real estate agents and brokers because it helps them to:

• Determine a fair and competitive listing price for a property
• Identify potential buyers and their price ranges
• Negotiate the best possible price for a buyer
• Provide valuable information to clients about the local real estate market

Here are some key points to consider when it comes to CMAs:

• A CMA is not an appraisal, which is a more formal and detailed evaluation of a property’s value.
• A CMA is typically prepared by a real estate agent or broker, while an appraisal is typically prepared by a licensed appraiser.
• A CMA is based on recent sales data and market trends, while an appraisal is based on a physical inspection of the property and a review of its condition.
• A CMA is usually less expensive than an appraisal, but it may not be as detailed or comprehensive.

The accuracy of Property Automated Valuation Models (AVMs) is a crucial aspect of the real estate industry. AVMs are designed to estimate the value of a property based on various data points, including historical sales data, property characteristics, and market conditions. While AVMs have improved significantly over the years, their accuracy can vary depending on several factors.

Challenges in AVM Accuracy

• Data Quality: AVMs rely heavily on data accuracy and completeness. Inaccurate or outdated data can lead to flawed estimates.
• Unique Property Features: AVMs may struggle to account for unique or non-standard features of a property that can significantly impact its value.
• Local Market Conditions: AVMs may not fully capture local market conditions, such as changes in supply and demand, which can affect property values.
• Lack of Human Judgment: AVMs are based on statistical models and may not consider human judgment and expertise in property valuation.

Measuring AVM Accuracy

AVM accuracy can be measured using various metrics, including:

• Hit Rate: The percentage of properties for which the AVM finds a match in its database.
• Record Count: The total number of properties the AVM has data for.
• Mean Error: The average difference between the AVM’s estimate and the selling price.
• Accuracy Rate: The percentage of valuations that fall within a specific range (e.g., 5%) of the selling price.

Conclusion

While AVMs have improved significantly, their accuracy can vary depending on the data quality, unique property features, local market conditions, and lack of human judgment. Industry-leading AVM providers, such as HouseCanary, have achieved exceptional accuracy ratings, but it is essential to consider these limitations when using AVMs for property valuation.

Zestimate Accuracy From Their Website:

How accurate is the Zestimate?

The nationwide median error rate for the Zestimate for on-market homes is 2.4%, while the Zestimate for off-market homes has a median error rate of 7.49%.

The Zestimate’s accuracy depends on the availability of data in a home’s area. Some areas have more detailed home information available — such as square footage and number of bedrooms or bathrooms — and others do not. The more data available, the more accurate the Zestimate value will be.

If you are thinking of selling and would like to dial in your home’s value in today’s market let me know and I will prepare a Comparative Market Analysis for you.

An Automated Valuation Model is a software-based tool that uses statistical modeling and a database of existing properties and transactions to calculate the value of a residential or commercial property. It is similar to a real estate agent’s comparative market analysis (CMA), which compares the values of similar properties at the same time.

However, unlike a CMA, an AVM uses data provided by the user, as well as existing data, to automate and streamline the process, and the results are only as good as the data available.

How does it work?

An AVM uses a wide array of publicly-available and user-submitted data, such as property type, size, general location, and comparable sales data (when available), to provide an immediate value estimate. This data is then analyzed using mathematical or statistical modeling and a combination of existing databases to estimate property value.

Types of AVMs

There are two main types of AVMs: Comparables Based AVMs and Hedonic Models.

• Comparables Based AVMs select comparables for each individual valuation based on the characteristics of the property to be valued. They operate similarly to how an appraiser would work when valuing properties through the sales comparison approach.
• Hedonic Models try to isolate the impact of individual property characteristics in the form of pre-calculated parameters. They do not select comparables based on the individual property to be valued, and the valuation result cannot be traced.

Advantages and Limitations

AVMs have several advantages, including:

• Time-saving: AVMs can provide an estimate of a property’s value in a matter of seconds, without the need for manual effort.
• Objective: AVMs are objective, as they are based on data, which increases the accuracy and reliability of the valuation.
• Cost-effective: AVMs can be more cost-effective than traditional appraisal methods.

However, AVMs also have some limitations, including:

• Limited data: AVMs are only as accurate as the data available, and may not take into account unique property characteristics or local market conditions.
• Inaccurate estimates: AVMs may produce inaccurate estimates if the data is outdated, incomplete, or incorrect.
• Lack of physical inspection: AVMs do not consider the condition of the property when estimating its market value, which may not be entirely accurate.

Overall, AVMs are a valuable tool for real estate professionals, investors, and lenders, providing a quick and cost-effective way to estimate the value of a property.

A: Most properties have three property lines setting the common boundaries with adjacent properties owned by others. A fourth property line usually sets the frontage on a public right of way, such as a street.

The location of the common property lines is typically represented by common boundary improvements such as shrubbery or trees. When setting up, maintaining or removing common boundary improvements, the
adjacent property owners’ rights depend on the type of improvement.

Common boundary improvements, other than trees, located on a property line between adjacent properties are called party walls. Types of party walls
include:

• boundary fences;
• driveways; and
• ditches.

Owners of adjoining properties are presumed to benefit equally from boundary fences. Under this legal presumption, all adjoining owners are equally responsible for constructing, maintaining and replacing
boundary fences.

The responsibility for constructing, maintaining or replacing boundary fences may be altered or removed only by:

• a written agreement between all affected owners; or
• an adjoining owner’s judicial petition to remove or alter their responsibility.

When trees mark a common boundary, each tree’s ownership is determined by the location of its trunk. Solely owned trees belong to the owner of the property on which the entire trunk is growing. Trees growing on government-owned parcels, such as a right of way for streets and sidewalks, belong to the local government, and thus the government is responsible for maintenance.

However, shrubbery or trees whose trunks stand partly on the land of two adjacent property owners belong to both adjacent owners. These trees are called line trees or common boundary trees.

Similar to maintaining a boundary fence, adjacent owners who own line trees are jointly responsible for maintaining the trees and, unless they agree to an alternate arrangement, share equal costs. To avoid disputes, adjacent property owners need to consider entering into an agreement detailing how they will handle the maintenance of boundary trees.
