I'd first create a task list of what needs to be done that will serve you whichever way you decide to go.Then divide the list to: things you MUST sub out (that may require license, knowledge, experience you don't have) and to things you can do yourself.Then further divide the list of things, you can do to worthwhile. ex painting can be easy but maybe getting a crew to do it will save lots of time and be done better?

National firms tend to serve large, institutional clients that need a firm that can handle multi-jurisdiction projects. 

Typically after missing a few payments the property will go into Pre-Foreclosure and the time between this and Notice of Sale being served are the golden hours (or. . . um . . . months or years?)

My question is how can I best add value to my mentor's business serving as general manager?

The only thing it does is weaken your negotiating position.I suspect that an attorney could use that to your advantage as there was no meeting of the minds, nor is there a contract in effect.One thing you might try is to send him a demand letter and have it served by a sheriff or constable, depending on how things are done in NC.  

I wouldn't try to serve a cease and desist to Checch and Chong directly. 

Apart from the ethics of serving my client’s best interest, by doing so my business grows and my own goals are met.

@Ashley BudyakI am currently in the same situation I recently got back from serving an LDS mission a for two years in the pacific islands and only have 3 months of work under my belt since.

@Dani Beit-Or to be clear you rolled out the red carpet to be terrified, all I am doing is serving your request to better live in fear for your properties, lol. 

This was not part of the original deal borrowers signed up for, but when you take Uncle Sam's money, you play by HIS rules, and he's been known to change those rules at a whim to serve his interests.
