Buy warm clothes and coats and see how many houses you can buy 6 months after we get a cold snap where it hits -20 to minus 30 degrees and doesn't get above zero degrees for 3 or 4 weeks . 

@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. 

.- Nice coat of paint and/or murals- Extra Amenities such as jacuzzi, pool, basketball court, bocce ball, arcade games, and etc

I credit that to having a slick hard many coats of enamel paint AND I did cure the source of excess moisture needless to say.

Most of the time, they just want a fresh coat of paint.

You'll pretty much know it WAS if the house was built in the 60s.Either way, we put 2 to 3 coats of oil-based polyurethane on the floor and lay something overtop, LVP is my go-to, and read that we wouldn't have any issues.

When you're done with the popcorns, get a pole sander (again, wear a dust mask), give the ceiling a light sanding, then coat with primer and a flat coat of paint (or just primer, if you prefer).

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

At full retail in my area you are looking at 2500-2800 for Sheetrock and a plaster skin coat for the 19 boards that you would need.

I know it's a lot more money than nail polish, but I'm just using that to illustrate the 'Your Thing" concept.Unless she is just dead set against it of course...in which case you will need to be a better salesman...You could always try the old "Mink Coat" analogy (or something along those lines).It goes like this, "I know you would like me to use this money to buy you a new Mink Coat (or vacation in Tahiti, or whatever), but if I do, the money will be gone forever.
