I did a background check and uncovered a crime from 20 years ago, but that he did time 5 years ago due to failure-to-report.

But who knows unless it is uncovered. 

Went through an inspection and uncovered a lot of things that should have been updated but was not.

Learning to let the other party break the silence has saved me so much money over the years and uncovered critical details that helped me close deals. 

For help uncovering all the risks and retards associated with lending your money out to other active investors, check out the book I co-authored called Lend to Live: Earn Hassle-free Passive Income in Real Estate with Private Money Lending published by BiggerPockets.com/lendtolive last summer.

Just like you did before, have a natural conversation with them and see what else you can uncover.

My online research has uncovered 5 firms.

and the end of at least one line uncovered.  

I would personally never waive inspections since there is no telling what can be uncovered during an inspection that would really change the quality of a given deal.

I don't mean to rant about Spain -I realize I do it often here- but I think there is value in uncovering the stark differences as a means to inform and slowly bring change...Un saludo,Dani
