@Jim K.I’m a big fan of the Socratic method.

Have another plumber run a camera to verify the work was completed and the issue has been solved.

If they bring me something else, the onus is on them.By the way, I work with a number of REA, and none of them have a problem with this, and all of them agree this method is one they prefer because it wastes far less time...and all of the agents are very experienced...and all of them are very good at filtering out properties before they bring them to me, so I rarely (less than 5% of the time), back out of a deal due to the inspection.

I'm particularly focused on those of us utilizing the Brrrr method. 

Its likely the most costly of the 3 options, however if time is more valuable than money, you can solve your problem.

I know this seems pretty broad but I have contacted the wholesaler I know to look for these but am unsure if that is the best method to go with. 

I like the idea of the brrr method.

Make sure that they have a good relationship with companies that will refinance the loan for you if you are using a BRRRR method.

You are relying on pure luck to get a deal with these methods.So again, why are you choosing these methods.

@Dave Foster - I love the Buy, Fix, Rent, Evaluate method you described.
