At an open house, look past the staging and check the bones of the home: signs of water damage, foundation cracks, the age of the windows and roof, and the electrical panel. Then walk the layout, storage, natural light, and noise. Ask smart questions, take notes, and keep your budget and your excitement to yourself.
Below is a checklist you can save on your phone and run in any home you tour.
What should you inspect at an open house?
The finishes are easy to notice and cheap to redo. The expensive problems hide in places sellers hope you skip. Slow down and look for the things that cost real money later.
Bring your phone for photos and notes, wear socks or shoes you can slip off, and give yourself time in each room. If a home is busy, come back near the end when it is quieter.

The big-ticket items: water, foundation, roof, and electrical
Start in the basement. Water is the most common and most expensive problem in a home. Look for stains at the base of walls, a musty smell, or a white chalky residue that signals moisture pushing through concrete.
