Asbestos test?

Well you are not alone. If possible the easiest fix is to cover it with new thin gyproc and paint or you can go the cheaper route and scrape it all off it is a huge mess and if it has been painted a couple of times will probably not work. Good luck

If it's not asbestos (which it probably is) and it hasn't been painted it is easy to remove, but be aware that popcorn ceilings were popular because the drywall didn't have to be installed and finished all that well and the popcorn hid it. I had a 2400 sq foot ranch that didn't have asbestos scraped a few years ago. It makes a huge mess, so do it prior to moving in, and unless you enjoy re-taping drywall and sanding I would probably hire a painter to paint the ceilings. Also, I had a neighbor that just painted theirs white and honestly, it looked a million times better, the popcorn just gets so dirty and there is no way to clean it. It needs to be painted with a sprayer though, or it will come off in chunks with a roller.
