"Property" means one individual hotel. Hotel chains are usually organized into regions. In a large chain, there may be several levels of organization: at the top, South America (where the chain may have a few hundred hotels or properties); within that, Brazil (where it may have 20-30 hotels); within that, Rio de Janeiro (where it may have three or four hotels). Those regional groupings are "above property level." Here, this phrase means that coaching and mentoring can be done at any of those higher levels.
