Real estate agents often use a combination of market knowledge, research, and experience to make educated guesses about which potential buyers are more likely to move forward with a purchase. Additionally, many real estate agents use professional tools, such as buyer profiling, to help identify potential buyers and understand their needs and preferences. Ultimately, the decision to buy a property is often influenced by a variety of factors, including personal finances, lifestyle, and the availability of suitable properties, making it difficult to predict with certainty who will ultimately purchase a property.
