Interior Wall & Door Damage
This picture illustrates several kinds of damage.
On the left you can see the vinyl covered wall board has been patched but the seams were not sealed. Since you can’t buy matching replacement wall board your repair choices are limited. The easiest process for most people will probably be to fill the seams with drywall compound and then prime and paint the walls.
The door may have to be replaced. If it were me, I would try scraping off the stickers and then painting the door. However, I suspect it will be hard to get to a smooth surface. Paint will probably show lines where the edges of the stickers were. If you want to keep the look of natural wood, scraping followed by a belt sander and stain might do the job. I guess the quickest method would be to test that on a small area. If it works, great. If not, buy a new door.
I looked at my high resolution original image to confirm that really is a keyed entry lock on the door. That plus the stickers makes an interesting statement about the interpersonal dynamics of the former owners.
