And can you capture longer stays through the slower times for less, when others are closed, boosting your income?

Non conforming units give a price bump, especially if they are nice units in my experience also and can be awesome for boosting rents during a house hack.

There are a million and one different ways to do "wholesalling", some of them are honorable and legal, while some of them are morally despicable and illegal, would you agree?

Moral: Formica makes it possible to change the look relatively cheaply.That said, on my next property I'm considering something different.

  $480K + $90K (near $110K) = $570K would have seemed more legit of an appraisal.I know he sold, but I do not know any of the details on how they handled the lower appraisal.The moral is that it is cheaper to buy a property with an existing ADU than to buy a property and add an ADU.Good luck

but i never get that kind of ARV boost with a 10K rehab.

You are MORALLY liable for maintenance and insurance, albeit not legally.  

"Wholesalers exist because the market needs them"- I have no moral objection to wholesaling, but can we at least be honest about it.

@Jay Hinrichs Developers definitely get presales to satisfy lenders and (they hope) to boost sales.
