Come up with your own "rule of thumb" based on your criteria and your market(s).1%, 2%, 50%, rules don't, and shouldn't apply to REI...they should apply to milk...as in,1% = Milk only a mother would love.2% = Milk that is growing in popularity50% = the increase per year in the number of people drinking 2% milk (I'm told this)

I cleaned a lot of barns and stalls, milked a cow daily, fed cattle, sheep, horses, and sometimes chickens when no one else was available.

If I want a certain skim coat depth on the drywall, I say that.

They also don't understand that the main purpose of the guru seminar they went to was to recruit cheap bird dogs and milk their personal networks for the guru's more established pals.Sooner or later, though, the burgeoning REIs DO happen on what they feel is a good flip opportunity.

@Jared SutherlandTo the best of my knowledge, you have a few choices, none really great) to address a popcorn ceiling (and asbestos notwithstanding):1)  Tear it down and re-rock (tape, spackle, etc)2)  rock with 1/4" board right over it.3)  There are commercial sanders to sand it all down (so you get lots of dust but don't need to hand board)4)  you "skim" coat the crap out of your ceiling..Also, to remove asbestos I think you legally need to use an EPA certified Contractor. 

Another option is to leave the popcorn ceiling in place and skim coat it with joint compound.

I've also seen good contractors skim coat right over the popcorn.

You might pick up the book “Guerrilla Marketing” (if it’s still in print) and skim through it.  

I don't support the idea of running large Airbnb operations which skim off too much inventory and lack the personal touch of local hospitality.

It felt like Edward was just skimming the surface without providing any real value or in-depth understanding of the subject.
