Most of an open house's value arrives after the doors close, and it decays fast. A visitor who toured a house on Saturday is a warm lead on Sunday, lukewarm by Tuesday, and by the following weekend they've toured three other houses with somebody else.
Capture something worth following up on
The sign-in sheet gets you a name and an email. The two-minute conversation gets you the thing that actually matters: their timeline, and whether they're buying, selling, or just live around the corner. Write it down between visitors. A contact list without context turns into one generic blast, and generic blasts get deleted.
The first 24 hours
Message everyone by the next morning. Short and specific beats long and polished: thanks for coming, one detail from your conversation, one useful next thing. For a serious buyer that's comparable listings or a showing time. For a neighbor it's a market update for the street. For the just-looking crowd it's nothing but a friendly note and a promise not to pester them.
Where it goes wrong
- Waiting until midweek. The lead didn't die; it just met another agent.
- Sending one identical message to the whole sheet.
- Following up like a closer. Nobody owes you a transaction for touring a house.
None of this is complicated. It just competes for the same evening energy as everything else on open house day, which is a good argument for making the rest of the day as light as possible.
