Real Estate Brokers and Virtual Offices

[Mark Arnold]

A client asked this question and I have received a bevy of answers and they all differ.  I can't locate the answer on the TREC (Texas Real Estate Commission) website either.  The old law is that a broker had to "hang" their license on the wall where they did business.

I know for a fact that there are brokers who have a Virtual Office but doesn't that contradict the Texas law?  Thanks!
