Your goal is to extract the most money as possible per month from as many people you can.

I agree that different operators can extract varying levels of value from the same property.

I don't see much wrong if an individual wants their barber to perform a tooth extraction or a blood letting, but the state wants dentistry, medicine...and even barber's to be licensed and to perform only the activities that they are licensed to do in order to protect the public interest.

Assuming no spending of the extracted equity on personal items (new motorcycle or motorhome for example) means that you could increase the portfolio equity position while expanding the cash flow in addition.2%/50%/30%+ seem to be the rules plus not spending equity on personal consumables.

In this case, you might want build in a prorated sliding scale commission for how much equity you are able to extract from each refinance. 

You cannot march into their homes any more than the bank can march into your mortgaged home either.Rather than get angry take this as a learning opportunity, an "oops" moment, than extracting revenge.If you're into the business of revenge, then there are much better opportunities in land lording than this.

This is generally reserved for national tenants as I want mom and pop to go up every year in case they go out early I have extracted maximum rent.  

There is a lot to consider in analyzing a property and cash flow is only one criteria as my initial cash neutral property has had all of my investment money pulled out and significant profit extracted (even with a bad appraisal), has had the rent increase from $2500 to $3135 (both market and rehab increase but one unit is $200 below market so market rent is currently $3335), and, even when ~cash neutral, was increasing my net worth (not counting market appreciation) $400/month via principle paydown.  

Owners who begin exit planning a few years before a sale can begin to extract themselves by putting more responsibility on key employees, which eases the transition between owners.

I had a tooth extracted this am, under the ibfluence of some good meds (LOL) so that's my short version, bottom line, I suggest your time will be well spent looking at your own long term properties.
