Which factor does NOT contribute to a decrease in property value?

The factor that does not contribute to a decrease in property value is the scarcity of housing in the area. In fact, scarcity can have the opposite effect on property values. When housing is limited and demand remains high, it usually drives property prices upward as buyers compete for the available homes. This phenomenon often occurs in desirable locations where the supply of housing cannot keep pace with the number of buyers looking for homes, thus enhancing property value rather than decreasing it.

In contrast, increased noise levels from nearby commercial developments, changes in zoning laws that may negatively affect the character of a neighborhood, and increased traffic from commercial development typically lead to decreased property values by making areas less desirable for potential buyers. Increased noise and traffic can create an unpleasant living environment, while unfavorable zoning changes may result in a loss of residential appeal or lower quality of life for the community.
