Price from the record, not the claim
A real listing said the collateral was worth $189,000. Three independent sources agreed on a $154,440–$163,534 range, and the deal was priced from its conservative end. Here's what that one gap did to every other number in the deal — and why the claim stays on the page, marked not independently corroborated.

Every number in a mortgage-note listing is the seller's claim until someone checks it. This is the story of one real listing — a single-family note listed as performing, in San Antonio, sanitized but otherwise untouched — and what happened when its stated value met the public record.
The listing, on its own terms
The seller stated a property value of $189,000 against an asking price of $130,000 and an unpaid balance of $146,171 at 9%. On those numbers the deal looks comfortable: a 77.3% loan-to-value, $42,829 of borrower equity above the loan (value − UPB), a $59,000 buffer above the $130,000 ask (value − price), and a 10.4% yield to maturity. Worth reviewing further — and honestly unverified, because at this point every figure is the listing's own.

The three independent sources agree with each other within tolerance and support a range of $154,440–$163,534; the report prices from its conservative end, the $154,440 underwriting basis. The seller's claim sits 22% above that basis and 16% above even the high end; no two independent anchors support it, so it reads not independently corroborated — not contradicted, because the vendor's estimates sit within tolerance of it and that word is reserved for a claim the anchors agree with each other against. That is not a rounding argument; it is $34,560 of claimed value — and with it most of the equity protecting the note — that the available record doesn't support.
One input, every consequence
The stated value is one input, but it sets the denominator under most of the deal. Repriced on the underwriting basis, the loan-to-value moves from 77.3% to 94.6%, the equity above the loan (value − UPB) falls from $42,829 to $8,269, and the buffer above the $130,000 price (value − price) falls from $59,000 to $24,440 — before transaction costs or any senior claims. Across the supported range the ITV runs 84.2% to 79.5%, and the recommended position does not change, so that spread is sensitivity rather than a blocker. The yield doesn't move — it's arithmetic on the note's terms, not the property's value — which is exactly why a yield alone can't tell you a deal is safe.
Where the deal landed
The report's position moved to Verify first: the deal was priced from the underwriting basis rather than the claim, but two questions still blocked any honest stance — the pay status rested on a stale ledger that ended 22 months before the listing's claimed last payment, and the county's one recorded mortgage sat close enough to the note's balance that it could be the note itself or a senior loan it wraps. Each question came with its owner and the exact evidence that would resolve it: a current servicing ledger, and a title report.
New evidence refines the position. It may strengthen it, weaken it or leave it unchanged.
And the $189,000? It stays on the page, marked not independently corroborated, permanently. An unsupported claim should stay visible — a report that silently swaps in the corrected number teaches the reader nothing about the deal they were shown. Whether the overstatement was optimism, stale information, or something worse is a question for the rest of your diligence; the report's job is only to show that the available evidence doesn't support it.
What this deal teaches
Three things generalize beyond this deal. First, the stated value is the single highest-leverage claim in a listing, because it silently sets the denominator under LTV, ITV and both equity measures — check it before anything else. Second, distinguish the claim from its consequences: one contradicted input produced four recalculated figures here, and treating those recalculations as separate problems double-counts one finding. Third, a deal can survive a contradicted value — this one moved to Hold, not Pass, because the corrected economics were thinner but not fatal; what actually blocked a stance were the two unresolved questions, each with a named piece of evidence that would settle it.
