Why it matters
A buyer scrolling listing photos sees a floor, a ceiling, a wall. Casaroo's job is to tell you when what you are actually looking at is water, or movement, or a structure that has shifted. Get this wrong in the optimistic direction and you budget for flooring when you needed to budget for a foundation.
How to spot it
Look for deformation, staining, and lines. That is the whole rule. Worn is cosmetic. Deformed, stained, or cracked in a line is mechanical.
What it costs
None of its own. This card exists to route you to the right one: mould and moisture, crawl space moisture, sagging and uneven floors, or foundation cracks, all of which sit on the mechanical side and carry the real numbers.
What to do
Do not price the finish. Ask what caused it. If a listing shows any of the five above, that is a Walkthrough or an inspection question, not a decorating budget.
Education and triage, not a home inspection. Casaroo will name the cue it can see in your photos and tell you which side of the line it falls on. It will never tell you a house is dry, level, or sound. We flag; we don't inspect, and we never clear.
