How a $0.25 Marble Could Save You Hundreds of Thousands
The simplest tool for spotting big property problems
When you think about inspecting a property, high-tech tools might come to mind. But sometimes, the simplest solutions are the most effective. Here’s one you might not expect: a marble.
That’s right—a $0.25 marble could save you hundreds of thousands of dollars by revealing structural issues before you invest. Whether you’re touring a new property or reevaluating an existing one, this small tool can provide big insights.
How It Works
Using a marble during a property tour is a straightforward way to uncover structural problems. Here’s how:
Place the marble on the floor in any room.
Observe its movement—if it rolls quickly, the floor isn’t level, and you might be looking at a structural issue.
Check multiple rooms to get a comprehensive view of the property’s condition.
