Help what am I doing wrong xD

I have ownership of a fc which houses a bunch of my alts. I have no other alts in any other fc's on this service account and no personal housing at all anywhere.

I've tried to relocate my house but it says I've reached the limit of houses I can own on this service account. Why can't I? What am I missing. I've read Squares rules on the situation and I def don't own more than one fc house on this service account. Just trying to relocate.
