What Is Comparable Property (Comp)?

A Comparable Property, or Comp, is a property used as a reference to estimate the value of another property, often used in real estate appraisals and market analyses.

Comparable Property (Comp): Estimating Subject Property Values

A Comparable Property (Comp) is a property used as a reference point to estimate the value of another property, often referred to as the subject property. This method is commonly employed in real estate appraisals, market analyses, and by real estate agents to determine fair market value.

Definition in Real Estate

In the context of real estate, a Comparable Property is one that is similar in key attributes to the property being evaluated. These attributes can include location, size, age, condition, and other relevant features. The value derived from comparable properties helps in arriving at a realistic market price for the subject property.

Importance of Comparable Properties in Appraisal

Using comparable properties is a critical element in real estate appraisal and valuation processes.

Factors Considered in Comps

  • Location: Proximity to the subject property plays a significant role, as neighborhood characteristics and local amenities impact property values.
  • Size and Layout: Square footage, number of rooms, and overall layout should be similar.
  • Condition and Age: The physical state and the age of the property must be comparable.
  • Features and Amenities: Presence of features like a garage, swimming pool, or updated kitchen.
  • Sale Date: Recent sales are more relevant, usually within the past six months to one year.

Historical Context

The use of Comparable Properties dates back to when real estate markets first emerged. Landowners and buyers have long sought reliable benchmarks to gauge property values. Formalization into appraisal practice became more prevalent in the 20th century, particularly with the development of standardized appraisal methods and increased regulation of the real estate market.

Methodology

Selecting Comps

The process involves selecting three to five properties that have recently sold or are currently listed that share key characteristics with the subject property.

  • Data Sources: Real estate databases, Multiple Listing Services (MLS), public records, and real estate agents.
  • Adjustments: Minor adjustments are often made to account for differences between the properties to ensure a more accurate comparison.

Example

If evaluating a three-bedroom, two-bath home with 1,500 square feet, an appraiser would look for homes with similar attributes in the same or a similar neighborhood that have sold recently.
