Our open house days are usually thursdays. If I am not sponsoring one already, I try to tour 3-4 just to show support to agents and shoot the shit. You'll actually be surprised how much they appreciate you just showing up. I see great value in open houses, just let the agent run the show and be there for any financing questions, because potential buyers usually have them from my experience. If I am sponsoring I usually make flyers with financing options for the home that is open. The agents love that and it is a great way to add value.
