Starter prompt

Build an open house web app for a listing agent who hosts weekend open houses. Each open house has an address, start and end time, host, status and a flyer PDF. Give each one a public sign-in page opened from a printable QR code sign, asking for name, buyer status, whether they have an agent (with that agent’s name, brokerage and email) and an email address with an unchecked opt-in box. Hosts sign in to see the visitor list for their event. Email a feedback form the next morning to opted-in visitors only, and build a seller report that counts price opinions without showing names or emails.

Overview

Who this open house app is for

Most open houses still run on a clipboard by the front door. Half the names are hard to read, nobody noted who already works with an agent, and the thank-you emails go out days later, if at all. An open house app gives every event its own QR code sign-in page, so visitors type their own details on their phones. During the event you see who is unrepresented, who is a curious neighbor and who agreed to hear from you. Afterward, feedback questions reach only the right people and your seller gets a clear summary.

Key features

What your open house app can do

  • QR code sign-in at the door

    Each open house gets its own public sign-in page. Visitors point their phone camera at the printed QR sign, fill in a short form and are saved straight to that event, with no handwriting to decode later.

    • A printable sign with a QR code for each open house
    • Phone-sized form for name, email, buyer status and representation
    • The property flyer shown on screen right after they submit
    • The same page on a tablet for visitors without a phone

  • Visitor list with representation

    Hosts see arrivals in the order they signed in. Back in the collection grid, saved views split sign-ins into unrepresented buyers, visitors with an agent, neighbors and, once feedback lands, private-showing requests.

    • The buyer’s agent’s name, brokerage and email kept with each represented visitor
    • Buyer status from ready now to just starting
    • A private-showing flag taken from the visitor’s feedback answer
    • Hosts sign in and see the open houses they’re covering

  • Feedback questions for sellers

    A short form sent after the visit asks what people thought of the price and the home. Answers roll up into a seller report that shows the pattern without revealing who said what.

    • Price opinion, a 1-to-5 rating, what they liked and any concerns
    • One response per visitor, linked back to their sign-in
    • Seller report with counts and comments but no names or emails
    • Your own notes added before the report goes to the seller

  • Follow-up emails with opt-in checks

    Scheduled jobs send the feedback request the next morning and later price-change notices, but only to visitors who ticked the opt-in box and haven’t unsubscribed since.

    • Feedback request emailed the morning after the event
    • Price-change notices to opted-in visitors of that listing
    • Held-back emails logged with the reason they were skipped
    • An unsubscribe link that marks the visitor as opted out

How it works

From prompt to a live open house app

  1. Describe your open house routine

    Tell Netiva’s AI agent what you ask at the door, how you note representation and what you send afterward. It drafts collections for open houses, visitors, feedback and follow-ups, plus the public sign-in page.

  2. Load this weekend’s events

    Enter each address, time window and host in the collection grid and attach the flyer. Ask the collection assistant to draft a few test sign-ins so the saved views have something to show.

  3. Try the door flow on a phone

    Open the sign-in page in the live preview, submit a test visit and annotate anything that feels slow or unclear. The AI agent reworks it, then you print the QR signs.

  4. Publish before the first open house

    Publish in one click, connect your own domain on the Starter plan or higher and switch on the next-morning emails. Each later edit is checkpointed, so you can roll back a change that misfires.

Examples

Ways teams use it

  • A solo listing agent with Sunday open houses

    Two properties, back to back. Each door gets its own QR sign, the visitor list shows who is unrepresented before the agent leaves, and the seller report is ready by Tuesday’s check-in call.

  • A team whose assistants host for the lead agent

    Assistants and newer agents sign in and see the events they’re covering, each with its own visitor list. On Monday the lead agent reviews every sign-in in the collection grid and decides who gets a personal call.

  • A broker’s open for local agents

    On a weekday preview for other agents, each visiting licensee signs in with Agent as their buyer status and their own brokerage. Their price opinions give the seller a read from working professionals before the public open house.

Good to know

Before you build

  • Say how visitor details will be used

    Sign-ins are personal data from people who are only looking. Put a short notice on the form, leave the opt-in unchecked, ask only for what you’ll use and delete old sign-ins on a schedule. State privacy laws may add duties.

  • Visitor follow-ups count as marketing email

    Under the US CAN-SPAM Act, commercial email needs your valid postal address and a clear way to opt out, honored within 10 business days. Other countries set their own rules — Canada’s CASL expects consent before the first message — so check the rules where you send.

  • Hosting doesn’t create a buyer agreement

    The app records representation; it doesn’t draft or sign agreements. Under NAR’s 2024 practice changes, hosting for the seller needs no agreement with visitors, but an MLS participant who starts working with a buyer needs one before a tour.

  • Visitors need a signal to sign in

    The sign-in page loads in the visitor’s browser, so it needs a data connection and won’t work offline. Keep a paper sheet for rural listings or basements and type those entries into the collection grid later.

Compliance note

An open house sign-in collects names and emails from people who haven’t hired you, plus their agent’s details second-hand. Say on the form how you’ll use them and that you may contact that agent, keep the opt-in unchecked, send visitor follow-ups only to visitors who opted in, put an unsubscribe link and your postal address in every email including the ones to agents, stop when anyone opts out and keep visitor contact details out of anything you share with the seller.

FAQ

Questions about building an open house app

Do open house visitors have to sign a buyer agreement before they walk in?

No. NAR’s consumer guidance says visiting an open house on your own, or asking an agent about their services, doesn’t require a written buyer agreement, and a host acting only for the seller doesn’t need one with visitors. Once an MLS participant starts working with a buyer, for example by finding homes and arranging tours, a written agreement comes before the first tour. The app records representation; your brokerage forms and state rules cover the agreement itself.

How does QR code sign-in work at an open house?

Each open house record gets its own public sign-in page, and the app turns that page’s link into a QR code you print on a sign. Visitors point their phone camera at it, the form opens in the browser and their entry is saved to that event. A tablet on the counter can show the same page for anyone without a phone.

How does the app handle visitors who already have an agent?

The form asks whether the visitor has an agent and, if so, for the agent’s name, brokerage and email. Those visitors get their own saved view, and the follow-up rules can hold marketing emails for them and send the feedback request to their agent instead. NAR’s Code of Ethics asks members to deal with a buyer under an exclusive agreement through that buyer’s agent unless the agent consents or the buyer starts the conversation.

Can I share visitor feedback with my seller without naming anyone?

Yes. The seller report is a page built from the feedback collection that counts price opinions and ratings and lists comments without names, email addresses or representation details. You add your own notes to the open house record first, then send the seller the summary by email or walk through it on your next call.

Can open house sign-ins go straight into my CRM?

If your CRM offers a REST API, describe the connection to Netiva’s AI agent and it can build a step that sends each opted-in visitor there, with the API key stored securely. Check your CRM’s API documentation first. Without an API, filter the visitor list by open house and copy the opted-in contacts across by hand.

Which Netiva plan do I need before printing QR signs with my own domain?

You can build the whole app and test the sign-in flow in the live preview on the free plan, with no credit card. A sign-in page on your own domain needs the Starter plan or higher, and the paid plans add capacity and features. Check Netiva’s pricing page for the current plans, then print signs once the domain is connected, so the QR codes never point to a temporary address.
