You sometimes need to be careful, depending on climate and construction specifics, what sort of paints you apply to the walls in modern buildings. Using vapor-closed paints (or worse, vinyl wallpaper) will not allow the drywall to dry to the interior and can result in mold and mildew growth. I don't know the characteristics of acrylic artists' paint, but there might be reason to be careful. One thing I've also been wondering about is if repainting every other year, even with vapor-open paints, would have a similar effect. So many rental properties just end up with layers and layers of paint.
