Asking the right questions at a showing is one thing. Actually looking at the house — really looking, room by room, system by system — is a separate skill, and it’s one most people don’t practice until they’ve already made a mistake or two.
I used to walk through a house the same way I’d walk through a museum: taking it in, forming impressions, moving on. It wasn’t until I toured a place with beautiful staging and only noticed the water stains on the closet ceiling three weeks later, during a second visit, that I realized impressions aren’t enough. You need an actual checklist, and you need to run through it every single time, even on houses you’re sure you love.
Here’s the one I use now.
Start Outside, Before You Even Ring the Bell
It’s tempting to walk straight in, especially if you’re running behind on a day with several showings back to back. But the exterior tells you a lot before you’ve seen a single room.
I look at the roofline for obvious sagging or missing shingles, check the grading around the foundation to see which way water is likely to flow, and glance at the gutters for standing debris or separation from the house. I also look at the siding or exterior walls for cracking, and at the driveway or walkway for major cracks or settling. None of this makes me an inspector, but it gives me a baseline before I’m distracted by interior finishes.
The Foundation and Structure
Inside, I look for cracks in walls near corners, doors that don’t close flush, and floors that feel uneven or slope noticeably in older homes. A little settling is normal in an older house. Diagonal cracking, doors that stick badly, or floors that visibly dip are worth flagging and asking about, even if the agent brushes them off as cosmetic.
Every Ceiling and Every Corner
I make a point of actually looking up in every room, not just the ones with obvious water fixtures nearby. Discoloration, bubbling paint, or a slightly different texture patch on a ceiling is often the first sign of a past or current leak. Same goes for corners near windows and closets — places that get skipped in a quick walkthrough but tend to show moisture problems first.
Test the Things You’re Allowed to Test
Most listing agents expect this, so don’t be shy about it.
Water Pressure and Drainage
I run the kitchen and bathroom faucets, flush the toilets, and watch how quickly the water drains. Slow drainage in multiple fixtures at once can point to a bigger plumbing issue rather than just one clogged sink. I also check under sinks for staining, warped wood, or a musty smell, since that’s often where a slow leak shows up long before it becomes obvious anywhere else.
Windows and Doors
I open a handful of windows throughout the house, not just the ones in the main living areas. Windows that are painted shut, stick badly, or won’t stay open on their own are a maintenance item worth noting. I also check whether they’re single-pane or double-pane, since that affects both comfort and energy costs down the line.
Outlets and Switches
I don’t bring a tester with me, but I do flip light switches and glance at outlets for obvious signs of age — like ungrounded two-prong outlets in an older home, or a panel that looks like it’s had a lot of unofficial additions over the years. If the electrical panel is accessible, I take a quick look and a photo, mostly so I can ask a more informed question about it later.
Walk the Systems, Not Just the Rooms
HVAC
I look for the age or model info on the unit itself if it’s accessible, and I ask whether it’s been serviced recently. I also just pay attention to whether the house feels evenly heated or cooled while I’m in it, since uneven temperatures room to room can hint at ductwork issues.
Water Heater
Same idea — I check the age if there’s a visible label, and I look at the area around it for rust, corrosion, or any signs of a past leak.
Attic and Basement, If Accessible
These two spaces tend to tell the truth more than any other room in the house. I look for insulation levels in the attic, any daylight coming through where it shouldn’t, and signs of pests. In the basement or crawlspace, I’m looking for moisture, efflorescence on the walls (that white, chalky mineral buildup), and any musty smell that lingers even with the lights on and the space aired out.
Take Photos of Everything, Even the Boring Stuff
I photograph panels, water heaters, ceilings, any cracks or stains, and the general layout of each room. It feels excessive in the moment, especially when you’re touring three or four houses in a day, but those photos become genuinely useful later — both for comparing houses and for showing an inspector or contractor exactly what caught your eye.
Why I Run the Same Checklist Every Time
It would be easy to get looser about this on a house I already like, and skip half the list because I’m mentally further along in picturing myself living there. That’s exactly the situation where things get missed. Running the same checklist regardless of how I feel about the house keeps the process honest, and it means I’m comparing apples to apples when I’m weighing multiple houses against each other later.
Final Thoughts
None of this replaces a real inspection, and it isn’t meant to. But a thorough walkthrough at the showing stage means fewer surprises later, a shorter list of open questions for the inspector, and a much clearer sense of which houses are actually worth pursuing to an offer.
FAQs
Do I need any tools for this checklist, or just my eyes?
Just your eyes, your phone, and a few minutes of patience. A flashlight can help in darker spaces like attics or crawlspaces, but nothing here requires special equipment.
Is it rude to open cabinets, run faucets, or flip switches during a showing?
No — this is completely normal buyer behavior, and agents expect it. It’s a much better use of the showing than a purely visual walkthrough.
What if I notice something concerning — should I bring it up on the spot?
It’s fine to ask about it in the moment, but you don’t need a full explanation right there. A photo and a note to follow up with your agent or inspector later is usually enough.
Does this checklist replace a professional home inspection?
No. This is meant to help you screen houses and ask better questions before you get to that stage, not to substitute for a licensed inspector’s evaluation once you’re under contract.
