Susan, and investor is usually looking for what they would consider a good deal.
Could the investor be scamming you? Yes that is possible...because they are looking for someone in a situation where they are in a hurry to get out of their property.
It is in your best interests to be represented by an Agent that you choose for your self, not one recommended by or working with the investor. Maybe try an internet search for agents in your zip code area. I wish you well.
