Here's a quick one that protects you more than it protects anyone else: if a seller hands you a copy of an appraisal from a pre-listing valuation or an estate, don't attach it to the MLS listing. Even if it feels helpful. Even if you have a legitimate copy. Why it matters to you: that report is somebody's licensed work product, built for one specific purpose and one specific reader — not for public marketing. Using it outside that scope isn't just a professional courtesy issue, it's a legal one, and it's on you as the person who attached it, not the person who handed it to you. Here's the piece most agents don't know: this has already gone to court and been decided. An appraiser sued a brokerage for using parts of his report in marketing material without permission — and won. That's not a grey area anymore; it's settled. Think of it the same way you'd think about the second sale on every deal — the one to the lender. You already know that report has to hold up to outside scrutiny long after your deal closes. The same logic applies here: what goes in that listing needs to be something you can defend, not something you borrowed. What's actually fine: your own measurements, your own floor plan, public record data, and a simple line like "priced below recent appraisal" if that's the strategy. What's not fine: the value opinion, condition notes, comps, or photos pulled straight from someone else's report. Here's something else worth understanding: reports often carry conditions you can't see just by reading a number. An appraisal might be based on a hypothetical condition ("as if" a specific repair or improvement were complete), an extraordinary assumption (something taken as fact that hasn't actually been verified), or a retrospective effective date (an opinion of what the property was worth as of a past date, not today). Sometimes the value or the data is entirely contingent on repairs or inspections that were supposed to happen before listing — and may or may not have. The client knows that context. You, as a third party looking at a number without the report, don't. That's another reason a number pulled out of context can create real exposure for you, even with the best intentions.
