Corrections policy
Last reviewed July 13, 2026
Mortgage Ledger publishes numbers that people use to make expensive decisions. Getting one wrong matters, so this page explains exactly how errors are reported, assessed, fixed, and disclosed — and how content that was right when it was written gets updated when the rules change underneath it.
How to report an error
Report anything that looks wrong through the contact form or by writing to pacificledgerstudio@gmail.com. You do not need to be certain, and you do not need to be an expert — “this number doesn't match what my lender told me” is a perfectly good report and is one of the most useful things a reader can send.
The report is much faster to act on if it includes:
- The page you were on.
- The inputs you entered, if it involves a calculator.
- What the site showed, and what you expected instead.
- The source you are comparing against, if you have one.
Please do not include account numbers, Social Security numbers, or copies of loan documents. They are never needed to reproduce a calculation error.
How corrections are evaluated
Every report is read. Reports about numbers are prioritized over everything else in the inbox. The assessment runs in this order:
- Reproduce it. The reported inputs are re-entered and the output is rebuilt independently — by hand or in a spreadsheet, not by re-running the same code that may be at fault.
- Locate the cause. An error is classified as one of: a calculation bug, a factual error about a rule, an out-of-date figure, an unclear or misleading explanation, a broken link or interface fault, or a typographical error.
- Check the blast radius. If a formula or a rule is wrong on one page, every other page that relies on the same formula or rule is checked and fixed in the same pass. Corrections are not applied to the reported page alone.
- Fix and verify. The fix is re-tested against an independently worked example before it goes live.
If a report turns out not to be an error — usually because the site and the lender are making different assumptions rather than different calculations — the reader gets an explanation of why, and if the confusion was caused by an unclear explanation on this site, the explanation is rewritten. That counts as a fault worth fixing too.
How corrections are disclosed
Mortgage Ledger does not quietly edit a page and move on.
- Material corrections — anything that changes a number, reverses a conclusion, or misstates a rule in a way that could affect a reader's decision — are disclosed on the page itself, in a dated correction note that states what was wrong, what it now says, and when it was fixed. The note stays on the page permanently. It is not removed after a decent interval.
- Significant clarifications — where the number was right but the explanation was misleading — are noted on the page in the same way.
- Minor corrections — typographical errors, broken links, grammar — are fixed without a note, since disclosing them would be noise rather than transparency.
- Any correction refreshes the last-reviewed date on the page.
- Where a reader's report caused the correction, they are told what changed.
A correction is never disguised as an update, and an update is never disguised as a correction. If the site was wrong, the page will say the site was wrong.
How outdated mortgage information is updated
Much of what this site describes is set by rules and figures that change on a schedule or change without warning: conforming loan limits reset annually, mortgage-insurance premium schedules change by agency action, tax treatment changes by statute, and rate context moves weekly.
- Annual figures — conforming loan limits, tax thresholds and phase-outs, premium schedules — are reviewed each fourth quarter and updated as soon as the responsible agency publishes the new values.
- Rule changes are applied as soon as they are identified. Where a change has a future effective date, the page states both the current rule and the date the new one takes effect, so a reader is not misled in either direction.
- Rate figures used to set context are dated on the page and sourced to the Freddie Mac Primary Mortgage Market Survey. Rates in worked examples are labelled as illustrative assumptions, not as quotes, so that an example does not silently rot as the market moves.
- Superseded content that can no longer be made correct is either rewritten or removed, not left standing. Where a page describes a rule that has since changed, the historical rule is kept only if it still applies to loans originated in that period — and it is dated explicitly.
- Every page is re-read and re-verified at least once a year regardless of whether anything appears to have changed.
