Final answer:
A reverse directory allows an agent to access past sale prices of properties and upcoming property listings. a) Past sale prices of properties is correct option.
Step-by-step explanation:
A reverse directory allows an agent to have access to the past sale prices of properties. This means that the agent can find out how much similar properties in a particular area have sold for in the past, which can help them determine the market value of a property.
It can also provide insights into market trends and help the agent negotiate a fair price for their client.
In addition, a reverse directory may provide information on upcoming property listings. This can be useful for agents who are looking for new properties to add to their portfolio or for buyers who are interested in seeing what properties will be available in the near future.
However, a reverse directory does not typically provide access to buyer preferences or seller credit scores. These types of information are usually obtained through other means, such as credit checks or surveys.
