@Pat Aboukhalen was the agent there sorting it all out for him there after his previous agent missed it - so if you don' already have an investor-friendly agent there that's who I would use. 

There are a couple of things that come to mind, if a payment is missed the lender cares, if the servicer goes out of business or misses a substitution of trustee, the lender cares, if the borrower goes to the lender to try to get removed from the loan (usually to buy another house) the lender cares, if the property gets caught up in a bankruptcy or divorce, the court cares and that means the lender gets involved.

Every time I change cleaners, I spend at least 3-5 hours retraining on my processes and expectations and even then things are missed.

That's often what I found to be missing...

I’d love to take you out for a drink!

I've seen people who meet everyone of my qualifications and turned out to be night mare tenants and also people who missed the mark of certain criteria and turned out to be my golden tenants. 

If they fail to pay the new full amount send a pay or quit for the missing amount with late fees.

I've been caught in my PJs, chasing my kids around in the front yard, drinking with a neighbor, etc.  

I only have one tenant who never missed a payment and was never late; coincidently, he is the only one who uses no assistance.

I currently have $350 dollars that is missing from a chargeback reversal from a tenant that has a document case with Amex and a statement to prove the money was sent back to me.
