Answer:
For banks, it depends on their regulatory agency is. Banks regulated by the Federal Reserve must use the words "Equal Housing Lender". FDIC and OTS regulated banks can use either "Equal Housing Lender" or "Equal Opportunity Lender."
Technically there is no requirement for the Equal Housing Lender logo for OCC regulated banks, but it is certainly advisable to use one of the two. While I couldn't find a specific citation, I believe a broker would fall under HUD, which requires the Equal Housing Opportunity and housing logo found here.
