Investor buyers don't fall in love with houses — they fall in love with verifiable numbers. The highest-leverage work you do on any STR listing happens before it goes live: building the deal room that lets a serious buyer say yes in days.
Every investor has been burned by inflated revenue stories, so self-reported numbers get discounted 20–30% in their underwriting — or torch trust entirely when the platform data doesn't match. Your rule as listing agent: lead with source documents. Spreadsheets only summarize them.
Audit the exports yourself, because the buyer's agent will: owner-stay blocks deflating occupancy, a one-off event year inflating the T12, cleaning fees padding "gross revenue" (platform and AirDNA-style figures include them), and any gap between what the seller "projects" and what the exports show. Whatever you find, the seller discloses first — volunteered honesty is credibility; extracted honesty is a price cut.

ACTION: Build your reusable deal-room folder template this week — one folder, the six categories above, blank and ready. At the listing appointment, the first homework you assign the seller is 15 minutes downloading their platform exports.
Next lesson: the permit question — the one answer you need in writing before you put any price on paper.
