I believe they found that I was very reasonable and understanding of both sides and appreciated how I looked for win-win situations.I put down a $5k deposit and they shared with me their deals.

I may not have enough to win a court case but I have emails of him needing certain documents like the BK balance and loan number which I found before it was too late and saved the deal because I knew it was public record Quote from @Marcus Auerbach: This sounds like a real dumpster fire.

However, if someone sues you and wins, they could take all of your rental properties.Better:Using a separate LLC for each rental property.

Successful investors don't get caught out (insert surprise) to win the long game.

All around win-win.  

If they come back I win, if they don't I don't lose.

Had that been factored in, my guess is floating rate “wins” closer to 90% to 95% of the time.  

No personal money in is a win.

So put up with the late, (put an end to it, tell them you will evict and sue for the entire balance of the lease, and will win ) typically this works. 

Win.
