Before you walk in
Sign-in sheets are standard, and most listing agents will ask for your name and contact info, sometimes your own agent's name if you have one. There's no obligation to give an email you don't want added to a mailing list, but giving at least a name and phone number is normal and expected; refusing outright can come across oddly in a small open house. Take your shoes off if there's a mat and a request at the door, and leave strollers and large bags in the car if the home is tight.
What to actually look at while you're there
It's easy to get swept up in paint colors and staging and forget to check the things that actually matter in six months. Walk the house with a short mental list:
- Water stains on ceilings or around windows, which can hint at roof or flashing issues.
- How doors and windows open and close, since sticking can point to foundation settling.
- Water pressure and drainage in sinks and showers, which is easy and quick to check.
- Cell signal and any obvious road noise, both of which are hard to un-notice after you've moved in.
- The age of major systems, if a disclosure sheet is available at the door; a furnace or roof near the end of its life is a real cost to plan for.
Questions worth asking the listing agent (and ones to save for your own)
The listing agent at the open house represents the seller, not you, which is worth remembering before you share anything you wouldn't want repeated. Fair game to ask them directly: how long the home has been listed, whether there have been other offers, why the owners are selling, and whether anything on the disclosure needs explaining. Better saved for your own buyer's agent, in private: your top price, how motivated you are, or any weaknesses you've noticed that you'd want leverage on later.
A 20-minute walkthrough, step by step
- Minutes 0–2 — Sign in and get the disclosure sheet.
Grab any printed property details and disclosure summary before you start walking.
- Minutes 2–10 — Walk every room once, unhurried.
Open closets, run a faucet, check outlets near where furniture would go.
- Minutes 10–15 — Go back to the room that worried you.
A second look at a small kitchen or an odd layout tells you more than the first pass.
- Minutes 15–18 — Step outside and look at the roof, gutters, and grading.
Water should slope away from the foundation, not toward it.
- Minutes 18–20 — Ask your questions and note the listing agent's name.
You'll want this if you make an offer later.
Common etiquette mistakes
A few things reliably annoy listing agents and other buyers alike: showing up in a large group that crowds small rooms, opening a refrigerator or medicine cabinet (yes, people do this), letting kids run through the house unsupervised, and lingering long past when you've seen everything while other buyers wait outside. None of these will get you kicked out, but they make the agent's job harder and can color how they describe you to the seller if an offer situation ever gets competitive.
A subtler mistake is narrating your opinions out loud while you walk through. Sellers, or a neighbor who's curious about the new listing, occasionally drop by during the open hours, and a loudly negative comment about the wallpaper or the layout has a way of getting back to the people who have to decide whether to negotiate with you later. Save the real reactions for the car.
What a strong turnout actually signals
Listing agents watch open house traffic closely, and the numbers tell a story worth knowing if you're seriously interested in the home. A busy first weekend is one of the clearest early signs that a property is about to generate competing offers:
If you walk into a house with a sign-in sheet already half full by noon and agents fielding calls at the door, that's useful information: it usually means you don't have the luxury of a slow decision, and it's worth deciding before you leave whether this is a home you'd actually compete for.
Should you bring your own agent?
For a casual Sunday-afternoon look, going alone is fine. If you're seriously considering the home, bringing your own buyer's agent, or at least calling them before you leave, means you get an advocate in the room who's working for you rather than the seller, and someone who can start the comparable-sales research immediately if you want to move toward an offer.
There's a practical reason beyond advocacy, too. Many listing agents will ask, right at the sign-in table, whether you're already working with an agent, partly to route you appropriately and partly because it affects how the sale gets structured. Walking in without an answer to that question, if you already have an agent, can create a bit of unnecessary confusion later about who represents you in a transaction. If you don't have one yet and you like what you're seeing, that's a reasonable moment to ask the listing agent for a recommendation of agents who aren't involved in this particular sale.
