Almost 100% it is because of one of two reasons: either the door gets broken and the tenant tosses it out rather than letting us know, or they take them off so they can use the closet without the doors (such as a nook office) and then put the door somewhere where it gets ruined (outside is popular, in the rain) or gets nabbed by hobos cruising neighborhoods looking for things to steal.

:)now, here's something... when we bought our house 13 yrs ago i knew nothing about remodeling. so when taking the wall paper off on one wall, 4 layers of wallpaper came off and some of the plaster. had no idea how to patch it, so we bought a bhear texture paint in a can that you apply with a special roller. and then we painted on top, so the bumps are smooth.so now, we have one accent wall in the house that's texture and everyone that walks in thinks it looks like art because we added some shapes that do not have the texture. even plasterers have commented on stealing that technique.. :)
