I'm doing what I believe to be the first and more affordable net-zero renovation home in the area through my company Attainable Home, and all the numbers worked not only for that (energy efficiency measures + solar) but also as a pure rental/BRRRR/investment or however you'd like to slice it depending on investor-type goals.

He said it’s not as easy as it looks because of measurements which I understand.

ROE is one metric for sure and it is important to measure correctly.

I'm assuming you would need to have a notepad with some general estimates like this:Replace kitchen cabinets:  $X per linear footRehab bathroom: $X per square footLaminate or eng. hardwood:  $X per square footPainting and sheetrock:  $X per square footThen when you are looking at the property you will need to do quick measurements of rooms.Is this the general way or is it much more general than this?

You know things are ridiculous when the judge makes a comment like that.I just hope the newly assigned judge can see all the delays and skumbag measures their attorneey has been taking to get all the adjournments for the last year at least???

In addition I never buy doors, trim, casing, or windows from Home Depot or Lowes as my local buidling supply houses are much cheaper and provide better service: they'll come out and measure everything and delivery is free if I spend $500 which is nothing in this business. 

I know there are many on here who would argue for a more measured "buy and hold" approach (this is a Bigger Pockets forum, afterall), but my guess is your average hotelier would argue the opposite (though I doubt many are on here to read this in the first place).For me personally, I started out relatively agnostic on which path to take.

The amount of stress that it’s eliminated from my life can’t be measured.

In that case, I request to review prior to purchase to check specs, measurements and dimensions (depending on materials of course) only because I have been in situations where the homeowner selected materials and it became a disaster because they did not measure anything. 

I'm leaning towards their service because they measure actual use instead of hot water use based rubs based, which seems to be the other option here in Oregon.
