Which sources are generally the least reliable for sales data?

The choice of newspaper articles as the least reliable source for sales data is valid due to several reasons. Newspaper articles may often contain inaccuracies, stale data, or subjective opinions that do not reflect the current market conditions. Unlike primary sources such as appraisers or actual sales records, newspaper articles can lack verification and may be based on anecdotal evidence rather than comprehensive analysis.

In contrast, appraisers and bankers typically rely on factual data and established methodologies when assessing property values. They have access to detailed transaction information and market analytics, which increases their reliability. Sellers, while potentially biased by personal interests, can provide firsthand information about their property and sale experiences. Therefore, newspaper articles are less dependable in delivering the kind of accurate, up-to-date sales data necessary for thorough real estate appraisal.
