Which of the following best illustrates the Principle of External Factors?

• A. The quality of interior finishes
• B. Proximity to a noisy street reduces value
• C. Brand-new appliances
• D. The number of bedrooms

Answer: (B)

External factors are elements outside a home's walls that influence what buyers are willing to pay. Being near a noisy street is a classic external factor because it affects desirability and calm living conditions, which can lower how much buyers are willing to offer—even if the interior is high quality. So this example best illustrates how things outside the property can impact value.

The other options describe internal characteristics: interior finishes, brand-new appliances, and the number of bedrooms all relate to what’s inside the home and its layout or features, not to external influences on value.
