The reasons to move could be one of many....death, divorce, relocation or change in financial status are just a few possibilities. Only the owner or someone close to them could speak with certainty. The listing agent should know, but due to confidentiality, should not forward the information. From looking at the timing of the listings, we would hazard a guess (and that's all it is) that the owners were enticed by the idea that they could possibly make a tidy profit on the sale. It would be difficult for many people to turn away from $3 million if it was offered. Just our thoughts.
