48% of Buyers Use Open Houses, Yet the Sign-In Sheet Ends Up in a Drawer. The Text Follow-Up That Turns Visitors Into Clients (HighLevel for Realtors)

TLDR

• According to the National Association of Realtors 2025 Profile of Home Buyers and Sellers, 48 percent of all buyers used open houses as an information source. The people walking through the door are actively buying.
• Most open house follow-up stops at a paper sign-in sheet that never gets typed up.
• GoHighLevel replaces the sheet with a QR code that opens a form on the visitor's phone.
• The form triggers an instant text with the listing details and the agent's contact card.
• A buyer or seller tag routes each visitor into the right 30-day nurture.
• A calendar link books private showings. Tasks remind the agent to call.
• Listing-alert emails keep the conversation alive after the nurture ends. The build fits inside the 30-day free trial.

Who This Is For

• Realtors who host open houses and cannot remember who came through last Sunday.
• Agents whose sign-in sheets are photographed, filed and forgotten.
• Teams that want every open house visitor in one CRM with the same follow-up.
• Brokers who want to see which open houses actually produce clients.
• Agencies serving real estate clients who want a HighLevel for realtors Snapshot with the open house form and nurture already built.

The Sign-In Sheet in a Drawer Problem

Open houses draw people who are in the market. According to the National Association of Realtors 2025 Profile of Home Buyers and Sellers, 48 percent of all buyers used open houses as an information source. Nearly half of buyers walked through a door like yours.

Then the follow-up breaks. Here is the cost chain.

• A couple visits your open house on Sunday. They write their name on the sheet.
• Their handwriting is hard to read. The email has a typo.
• Monday is busy. The sheet goes in a folder.
• Wednesday you type up the names. Two are unreadable. Three are not typed at all.
• You send one email on Thursday. It says "Thanks for visiting".
• No reply. You move on.
• Three weeks later they buy through the agent who texted them the same afternoon.

The visitor was not lost at the open house. They were lost in the gap between the sheet and the first message.

Why Paper Sign-In Fails

• Nobody follows up the same day.
• Data entry adds a delay and errors.
• Every visitor gets the same message, whether they are buying, selling or browsing.
• The agent has no reminder to call, so the call never happens.
• There is no record of which open house produced which client.

The fix is a form, a text and a nurture. Per visitor. From the doorstep.

What GoHighLevel Sets Up

Seven components. Together they are the open house follow-up.

1. QR code to a HighLevel form at the door. A Sites > Forms page with name, mobile, email, timeframe and a question: are you buying, selling or both? Printed as a QR code on a stand at the entrance. Why it matters: the visitor types their own details on their own phone. No handwriting, no typing later. Example: "Scan to sign in and get the listing details sent to your phone." Impact: every visitor becomes a clean contact before they leave the hallway.
2. Instant SMS with listing details. The form submission triggers a text within seconds. It contains the address, price, a photo link and the agent's name. Why it matters: the visitor now has your number saved in their phone with the house they liked. Example: "Thanks for visiting 14 Elm Street. Here are the details and photos: [link]. Reply with any questions. Sarah." Impact: you are the first agent in their messages, on the same day.
3. Buyer or seller tagging. The form answer applies a tag: buyer, seller or both. A seller tag also creates a task to call about a valuation. Why it matters: a seller walking through an open house is checking out the competition. That is a listing lead. Example: a neighbour ticks "selling" and the agent has a call task by the time the open house ends. Impact: listings come from open houses, not only buyers.
4. 30-day nurture by tag. Buyers get a sequence about the area, financing steps and similar homes. Sellers get a sequence about pricing, preparation and a valuation offer. Alternating SMS and email, spaced over 30 days. Why it matters: most visitors are not ready on Sunday. They are ready in three weeks. Example: day 3 text, "Two similar homes just listed nearby. Want the details?" Impact: you stay present until the visitor is ready to act.
5. Calendar link for private showings. Every message carries a link to a Calendars booking page. Why it matters: a visitor who wants a second look can book it without calling. Example: the day 5 text says "Want a private showing? Pick a time here." Impact: showings appear on the agent's calendar with no back-and-forth.
6. Task reminders for the agent. The workflow creates tasks: call within 24 hours, call again at day 7, check in at day 21. Why it matters: automation handles the texts, but a human call still closes. Example: Monday morning the agent opens HighLevel and sees eight call tasks from Sunday's open house, with the form answers attached. Impact: the calls happen because they are on a list.
7. Listing-alert emails. After the 30-day nurture, buyers move to a long-term list that receives an email whenever a matching listing goes live. Why it matters: the visitor may take months. Example: a monthly "new listings in your range" email built as a reusable template. Impact: the relationship continues past the first month at no extra effort.

For agencies: the form, QR code template, tags, nurture and task workflow go into one Snapshot. Every realtor client gets the same open house engine. Only the agent's name, calendar and listing links change.

Niche Starting Point

HighLevel publishes a Real Estate Agent Playbook bundle for real estate agents. It ships pre-built forms, workflows and page templates you can load into a fresh account and adapt to the setup below. Start the account from the 30-day link at the end of this post rather than the bundle page's own trial button. The trial is longer and the bundle loads the same way.

Step-by-Step Setup

1. Settings > Phone Numbers. Buy or port a local number. Complete A2P 10DLC registration before the first open house. Unregistered numbers get filtered or blocked on US carriers.
2. Settings > Tags. Create tags: open-house-visitor, buyer, seller, buyer-seller, showing-booked, long-term-buyer.
3. Settings > Custom Fields. Create a text field called Open House Address and a dropdown called Timeframe with values 0-3 months, 3-6 months, 6+ months, browsing.
4. Sites > Forms. Build the open house sign-in form: first name, mobile, email, buying or selling or both, timeframe. Add an SMS consent checkbox with plain wording. Hide a field that pre-fills the Open House Address from the URL.
5. Generate the QR code. Take the form URL with the address parameter and turn it into a QR code. Print it on a stand for the entrance. Make one per listing.
6. Calendars. Create a Private Showing calendar with 30-minute slots, buffers and the agent's availability. Copy the booking link.
7. Automation > Workflows, instant text. Trigger: form submitted, open house form. Actions: apply open-house-visitor tag, send SMS with listing details and photo link, send email with the same content, create a task for the agent to call within 24 hours.
8. Automation > Workflows, tagging. In the same workflow, add if/else branches on the buying or selling answer. Apply buyer, seller or buyer-seller. For seller and buyer-seller, add a task titled "Valuation call".
9. Automation > Workflows, buyer nurture. Trigger: tag added, buyer. Send a 30-day sequence alternating SMS and email, each with the Private Showing calendar link. Add tasks at day 7 and day 21. Exit condition: appointment booked on the Private Showing calendar.
10. Automation > Workflows, seller nurture. Trigger: tag added, seller. Send a 30-day sequence on pricing and preparation, with a valuation booking link. Exit condition: appointment booked.
11. Automation > Workflows, long-term list. At the end of the buyer nurture, apply long-term-buyer. Build an email template for listing alerts. Send it to the long-term-buyer tag whenever a new listing goes live.
12. Test. Scan the QR code yourself. Confirm the text arrives with the right address. Confirm the task appears. Book a showing and confirm the nurture exits.

Compliance notes. Register A2P 10DLC before texting US numbers. Put SMS consent on the form. Include opt-out wording in the first text. Do not text visitors who did not consent. Check your state's real estate advertising rules for what a listing text must include.

FAQ

What is open house follow-up in HighLevel? It is a QR code form at the door that captures each visitor, an instant text with the listing details, a buyer or seller tag and a 30-day nurture with a showing booking link and agent call tasks.

Do I need a special app for the QR code sign-in? No. The QR code points to a standard Sites > Forms page. The visitor opens it in their phone camera and submits. The workflow does the rest.

How fast does the visitor get the text? Within seconds of submitting the form. The workflow trigger is form submitted. The first action is the SMS.

Which HighLevel plan does a realtor need? The $97 Starter plan covers forms, workflows, calendars, tags and SMS for a single agent or small team. The $297 Unlimited plan suits brokerages with several agents and agencies serving multiple realtors.

Is there a free trial? Yes. HighLevel offers 30 days free. You can build the form, the QR code and the nurture inside the trial and run it at your next open house before paying.
