First Open House (days after receiving my license)- Help ! :)

[Westin Hudnall]

Good evening everyone !

I received my real estate license today and was given my first open house by another realtor in our firm to be held Sunday ; 2 days from now.

It also happens to be a 5000 sq ft $400,000 property which is upper end for the Midwest.

Need advice on what to do to host the open house and to help market myself at the open house ?
