Rudey, National or International Organizations Do Not Own Chapter Houses!
I can only Speak for LXA, but we have a Group that is volanteer who will help in financing. Each Chapter has a Housing Corporation that either owns the Chapter Houses or have authority over them.
Your questions seem to be redundint.
They Do Not Own the Houses, how about Yours?
Does Your Greek Organization OWN ALL OF YOUR CHAPTER HOUSES?
Da I say NO!
