Grace Porritt ,it is illegal to host an open house for a Realtor all by yourself without a license.Under the law you can do everything for the Realtor except talk to the visitors about the property or attempt to persuade anyone to buy that property or any other property.You can serve food and drinks,set up and take down the signs around the neighborhood,Greet guests and have them sign the registry,keep their children occupied while the Realtors work with the adults,and basically guard the front door while the Realtor walks through the property with the guests.You can never answer any questions whatsoever about the property.You basically have to say " the Realtor will be with you shortly" and "Thanks for visiting today".

They can rip the entire property to pieces and there is many reported stories of them hurting or killing children.

You should probably furnish the house with furniture that can hold up well to rough handling (no dainty fabric furniture).
