I have a home, because I was mining and found a decent diamond/iron/redstone spot. I recently finished what i wanted to do there, but i no longer want my home. I dont have multihomes, so I only have one, but I dont know how to unset it as my home. Is that possible? I saw that you can use /dehome <homename>, but I never named my home I only typed in /sethome, sooooo do i need multihomes to get rid of my home? I hope i dont, but we'll see, I guess.
Once you find the next place you want to set a home, just do "/sethome" again. It will save the new location over the previous location. You don't need to have multi home to be able to change the location of your home. Hope this helps
