How many years must commission members reside in Delaware before being appointed?

The correct answer is that commission members must have resided in Delaware for five years before being appointed. This requirement helps ensure that members of the commission have a significant understanding of the local real estate market, laws, and community needs, which is crucial for making informed decisions that affect real estate practices in the state.

Having a five-year residency requirement ensures that the appointed individuals are familiar with the specific challenges and opportunities within Delaware, allowing for informed governance and oversight of the real estate profession. This residency requirement can promote local representation and accountability, as commission members are likely to be more in touch with the needs and interests of Delaware residents.

The other options representing different lengths of residency do not align with the established requirements, thus reinforcing the importance of this specific duration to fulfill the role effectively.
