Motivation is an emotional state. 2 people subjected to the same environment will inherently act differently and thus proves it is not possible to target motivation.A motivated seller is not someone in foreclosure or is an absentee owner or is in tax trouble.A motivated seller is anyone willing to sell their house below market value no matter the reason.Everyone, please stop telling others to stay consistent.Let me tell you something, coming from a (NASA) scientist and engineer.When something does NOT work, you don't "do more" you don't stay consistent.

Feel free to reach out with any questions!
