Yellow tag fail.
As a Realtor, you probably get questions about everything from where the clay came from for the roof tiles (seriously, this has been asked), if the home has heated floors underneath the carpet, what year the new windows were installed, what brand of fan the secondary bedroom has, down to the energy star rating of appliances. The real estate practice is a constant pop quiz and therefore, you should know that not all LG models meet Energy Star standards, so you should cover your butt by knowing this tidbit of knowledge as you just might get that question!
