A home in Massachusetts, which had not been listed on the MLS, was sold to a buyer who was represented by an agent. Interestingly, this very agent proceeded to list the same home on the MLS for sale, just one day after the new deed had been officially recorded. What's worth noting is that the current listing does not display any historical sales information. Now, a question arises: Is the listing agent obligated to disclose the sale, considering they are the same agent who handled both sides of the transaction?
