An open house can be one of the most powerful tools for attracting buyers, generating leads, and closing deals — but only if it's done right. Even experienced real estate agents can fall into common traps that sabotage their efforts. Here’s a look at the biggest mistakes agents make during open houses — and how you can avoid them to maximize your success.

One of the most important steps during an open house is collecting visitor information — yet many agents forget or fumble this part. Without guest registration, you lose valuable leads and have no way to follow up later.

The good news? Showable makes guest registration effortless. You can create a simple sign-in form that visitors can fill out from their phones, no clipboards or awkward conversations required.

It’s one thing to collect visitor info — it’s another to actually use it. Many agents fail to promptly add open house guests into their CRM, meaning follow-up gets delayed (or forgotten altogether). When you use Showable, your open house leads are automatically synced to your CRM, saving you time and ensuring no one slips through the cracks.

The open house doesn’t end when the last guest leaves. If you’re not following up quickly — ideally within 24 hours — you’re missing a huge opportunity to turn interest into action. A simple thank-you message, a personalized listing recommendation, or an invitation to another showing can make a big difference.

An open house is about more than just the property — it’s a chance to build trust. Agents who rush through conversations or treat guests like transactions often miss out on future opportunities. Focus on being helpful, personable, and genuinely interested in your visitors' needs.

Especially after recent legal changes and settlements, it’s critical to stay compliant with the National Association of Realtors (NAR) rules. Make sure you’re clearly communicating representation, avoiding misleading statements, and protecting client data.

You can’t expect people to show up if they don’t know the event is happening! A few social media posts the night before aren’t enough. Start marketing your open house at least a week ahead of time through email blasts, social media ads, online listings, and your personal network.

Visitors appreciate takeaway materials like feature sheets, neighborhood guides, or mortgage information. It gives them something to review later and keeps your listing top of mind. Plus, it subtly reinforces your professionalism.

Timing matters. Hosting an open house during work hours or on a holiday weekend can drastically reduce turnout. Typically, Saturday or Sunday afternoons between 1-4 PM work best — but always consider your specific market and season.

An open house isn’t just about putting a sign out front and hoping for the best — it’s a strategic opportunity to connect with buyers, build relationships, and generate serious momentum for your listings. By avoiding these common mistakes and putting the right systems in place, you’ll not only make your open houses more effective, but you'll also stand out as a trusted, professional agent in a competitive market.
