Only members of MLS and Houston Association of Realtors can schedule open Houses. If you're a realtor, then through matrix or through your HAR app . you can manage your open houses. If you're the seller ~ talk to your licensed real estate professional.
When in Matrix, click on the Add/Edit (Input) button on the main bar. Then select a listing. Find the home you want to hold open, then fill out the information. As another agent mentioned, your open house date/time will also show up on the real estate search portals such as Realtor.com and Trulia.com.
Always advisable to do this early, 4-6 days before the open house so everyone will see it. Don't forget to promote on other sites like social media This is the Dashboard (not Matrix) under Agent Tools. Look for Facebook Ads. They have made it easy for you to create an ad.
