Why it matters
Listing photos are marketing, produced by a professional whose job is to sell the home. That is legitimate and expected. But it means the photo set is a curated argument, and like any argument it is more revealing for what it omits than for what it asserts. Casaroo scores this explicitly. It tells you which systems the photos covered and which they did not, and it recommends a Walkthrough when the mechanicals are invisible. That is not a technicality. In most listings, the things that cost the most money are the things nobody photographed.
What it costs
Nothing. Asking is free.
What to do
Ask for the photos that were not taken. The panel with the door open. The furnace and water heater labels. The roofline in daylight. The rooms that were skipped. An agent who wants the sale will send them, and the response itself is information.
Education and triage, not a home inspection. Casaroo reads what is in the photos and is explicit about what is not. It never scores a system it cannot see, and it never lets a beautiful photo raise a mechanical score. We flag; we don't inspect.
