open house compensation

[Muriel Hair]

i did an open open house for a coworker  .  if a visitor to open house person is currently working with an agent and they purchase the property after attending the open house, am i entitled to a commission

[Craig Wilcox]

Short answer, no, unless you are the procuring cause of the sale.  

Generally, the listing agent and the buyers agent will get a commission no matter who hosts an open house.  Most agents consider hosting an open house as an opportunity to find prospective buyers that do not yet have an agent.
