I intended it to be a BRRRR that was unlikely to extract entire investment.  

It is by taking equity, extracting out via HELOC/REFI/Sale, that you effectively grow your net worth.When you monitor ROE, you can see which properties are doing well and which ones aren't.

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

Tertiary markets in KY with an abundance of brick 4plexes built in the 70's, for which I had to hire a software engineer to forcibly extract property data from county sites because the records are not available on any batch data services, just one off searches on county records. 

A good real estate agent will bring value to a property owner and get their property sold for the highest price.A good wholesaler will get the lowest price and extract the most value away from the property owner for themselves and the investor.If a property never hits the open market there is no way its true value will ever be determined.

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

I talk with him/her and ask them after they have written up the appraisal, and say... okay so you say based on the condition and comps this property is worth 100K what in your opinion will I need to do to this property to get it to (x amount) usually equal to current purchase price plus budget plus a minimum of 25% more..ie: purchase at 100K20K down payment80 K mortgageRenovation cost of 15K100 + 15 = 115 x 1.25 =  144KThis means I can now open up the back end of the mortgage product for the 144K and extract my full down payment and reno costs.

So as not to shill for him, I'll let you extract that info on your own.
