Shell script that lists files with different owner than the folder

Hello, I'm trying to write a script which is listing files based on different preferences, like filetype or permissions. All is fine, except for one: I want to list files in /home which has a different owner than the home directory it is in.

Here is an example:
/home/UserA is the directory, and /home/UserA/foobar.txt is the file, that is owned by UserB.
If I would have to use a fixed user, this wouldn't be a problem, as I could just do

Code:

find /home/UserA \! -user UserA -exec echo "{}" is not owned by UserA \;

But I don't know, how can I use variables, that modifies the output and the checking based on who's home directory (for a /home/UserB/foobar.txt owned by UserA scenario) it is in. I was thinking about using awk to get the owner of the home directory and the file and compare it, but it doesn't feel right.
Basically I just have to find a way, to cycle through the home directories and replace the 3 UserA in my script, like this:

Code:

/home/UserA
/home/UserB
/home/UserC

find /home/UserA \! -user UserA -exec echo "{}" is not owned by UserA \;
find /home/UserB \! -user UserB -exec echo "{}" is not owned by UserB \;
find /home/UserC \! -user UserC -exec echo "{}" is not owned by UserC \;

I would appreciate any idea.

install

install(1)						      General Commands Manual							install(1)

Name
       install - install binaries

Syntax
       install [-c] [-m mode] [-o owner] [-g group] [-s] binary destination

Description
       The  binary  is moved to destination.  If destination already exists, it is removed before binary is moved.  If the destination is a direc-
       tory then binary is moved into the destination directory with its original file-name.

       The command refuses to move a file onto itself.

Options
       -c		   Copies binary to destination.

       -g group 	   Specifies a different group from group staff for destination.  The destination is changed to group system; the -g group
			   option  may	be used to specify a different group.  The user must belong to the specified group and be the owner of the
			   file or the superuser.

       -m mode		   Specifies a different mode from the standard 755 for destination.

       -o owner 	   Specifies a different owner from owner root for destination.  The destination is changed  to  current  owner.   The	-o
			   owner option may be used to specify a different owner, but only the superuser can change the owner.

       -s		   Strips the binary after it is installed.
