Which of the following is NOT a source of rental income data?

Internet listings are typically not a reliable source of rental income data. While they provide a wealth of information about available properties for rent, they often only reflect current listings rather than actual rental income achieved. Many listings may be inflated or not indicative of the true market conditions, as they can change rapidly and may not represent typical rental values over time.

In contrast, commercial property managers are actively involved in the market and have firsthand knowledge of rental income from their properties. They can provide accurate and detailed data based on their direct experiences and management practices. Similarly, sellers of comparable properties can offer insight into how much rent they have been able to command, which is typically based on actual financial performance rather than projected by listing prices. Public records also serve as a valuable source, as they can include historical rental rates and information on leases that have been recorded, thereby providing a more grounded understanding of rental income in the area.

Understanding the reliability and context of the data is crucial for appraisers, as they need to ensure they are using sources that reflect actual market conditions rather than speculative or variable information.
