It's twofold, I think - first is the psychology of "I was here before you so this is my place" or what I like to call the substitute teacher syndrome; second is they were screened (or not) by someone else using different criteria from your business model.Kudos to you for doing this transaction right and using the estoppel!

And there are states that are really starting to crack down on this activity because of the abused seller syndrome... but I am sure since you have other sources you will figure it out...its always good to get both perspectives  you make the choice of how you want to proceed and act based on feedback you get. 

The government takes the money out of the poor tax payers pockets (reverse Robin Hood Syndrome?)

Educate yourself constantly on your market and the business and you’ll beat that feeling of imposter syndrome quickly.

As a criminal they loose their rights and custody is given to the state who then finds a good home where the child will be taken care of and taught properly, thus breaking the cycle of perpetuating the babies we cant take care of syndrome.

I have a condition that is frequently described as burnt out landlord syndrome.. that happens when you are tired of tenants and tired of PM's sending you e mails requesting money..

@Paul Stout -- You're absolutely right about the shiny object syndrome.

And wholesale prices of these houses from owners that have an advanced case of burnt out landlord syndrome and other home sellers have gone up... from what I fund I see price's at wholesale have risen about 20 to 30% in the last 24 months.. and some markets even more Like parts of ATL where wholesale has double.. and Vegas were it tripled
