In real estate, what does effective age indicate?

Effective age reflects the perceived age of a property as determined by its condition and any improvements made over time. It is an important factor for appraisers because it provides insight into how well a property has been maintained and how much it resembles a newer structure. For example, a building may be 30 years old in actual age, but if it has received numerous updates or renovations, its effective age could be considered much younger. This concept allows appraisers to assess a property's value more accurately based on its operational functionality and aesthetic appeal rather than solely relying on its chronological age.

The other options do not capture this nuance; the actual age of a building simply states how long it has been since construction, while the total lifespan refers to the expected duration a property can function effectively. Market value, on the other hand, can be influenced by many factors beyond effective age, including location and market trends.
