what could he be taking pics for?

I moved out of my dads house Sunday. We took what we could after a lot of drama ( I have another post explaining it) we did leave a lot of stuff bc all we had was my car to pack. We had some clothes, the bed, vanity, chair, entertainment center, a dresser, and a few small things. Some of those things were my dads. My dad and step mom went into my room early Monday And took pictures. I made sure to not leave trash or anything. What we did leave I cleaned up. I just don't understand what their point was. We still have 30 days to leave just like the police said when they were called. We have to be totally out by may 15th. What could they be trying to do? I took pictures of how we leave things yesterday as well.
