When a prospect announces that he has already made a large number of visits, it is important to exercise a certain amount of judgment to assess his credibility. While this may indicate a high level of interest in purchasing a property, there are a few things to consider:

1. Credibility of the prospect: The credibility of a prospect depends on his reputation, his previous behavior, and his ability to provide accurate information. If the prospect has already had positive interactions with your agency or if you are dealing with an established client, it is more likely that their statements will be credible.
2. Motivation: Ask the prospect why he has made so many visits without having found a property that suits him. There may be valid reasons, such as very specific needs or special circumstances.
3. Level of market knowledge: If the prospect is well informed about the real estate market, he may have a clear idea of ​​what he is looking for, which could justify a high number of visits. However, if he does not appear to have adequate market knowledge, this may raise doubts about the credibility of his statements.
4. Consideration of advice: It is important to know whether the prospect has considered the advice of real estate agents during their previous visits. If a prospect has made numerous viewings and is not open to recommendations or adjustments in their search criteria, this can make finding the perfect property more difficult.
5. Documentation: Ask the prospect to provide proof of past visits, such as showing reports or communications with other real estate agents. This can help establish the credibility of one's statements.
6. Specific requirements: Make sure you understand the prospect's specific requirements. If they have very specific property needs, this may explain the high number of viewings. Make sure these requirements are well documented.
7. Openness to Collaboration: Discuss the prospect's willingness to collaborate with you as a real estate agent. Make sure the prospect is willing to listen to your advice and work together to find the perfect property.

Ultimately, the credibility of a prospect who claims to have made a large number of visits will depend on several factors, and it is essential to ask questions, listen carefully, and gather information to evaluate the situation. Open and transparent communication with the prospect is also important to establish a relationship of trust and understand their specific needs.
