Losing $50k through this is not ideal, but I’m fortunate that it is not a painful sum to lose.What I am seeking is advice on how to leave evidence in the public record that could be found by future landlords and limited partners vetting the GP, who’s seeking $8M total / $250k each from accredited investors per facility as he seems to have a plan to move around the country opening facilities.A $57k bill could be a devastating to many landlords, and I want to help prevent them from experiencing a similar situation.
