The report I underwrote off was addressed to the seller, not me
Small mixed-use building, two retail bays and four apartments over. Seller had a pre-listing inspection done six weeks before I got there, 38 pages, photos, a roof section that read like someone who'd actually been up there. I read it twice, priced my repair reserve off it at $61,000, and went hard on the earnest money at the end of a short diligence window because I thought the condition question was answered.
My own lawyer asked the question I hadn't. Who is the client on that report. The answer was the seller. The agreement had the standard clause limiting use to the named client, and the inspector's E&O sits behind that. So I asked for a reliance letter naming me. The inspector said no, which he's entitled to do, and offered to re-inspect for full fee.
That cost me $1,850 for a second inspection plus a $650 sewer scope I could have ordered on day one, and about twelve days of a 21 day window. I lost the negotiating runway. I asked for $34,000 against a new report that mostly matched the old one, and took $11,000 because I was out of clock.
What I'd do differently. Treat any report I didn't commission as a checklist of what to look at, never as a condition finding I can price off. And order the specialist scopes on day one rather than after the general report tells me to, because the general inspection was never going to cover the lateral anyway.
