Water dripping in and onto the carpet. The wet spot grew even larger than that and has happened many times after.
This is a water stain, it wasn't on the wall when we did the walk through. But was there the day we went to move in. I guess it's not a priority for the builder to fix it. It's going to lose them a sale of a house! We're allergic to mold and I shudder to think what's growing inside the walls.
