For appraisers · WA + OR · live

Build the workfile with proof of every source.

North Star helps you assemble a residential appraisal workfile with proof behind every fact. You upload your source files — engagement letter, comps, county records, photos — and North Star reads them and records where each one came from. Field captures from the mobile app land on the assignment too. When you seal the workfile, that record proves you can trace every fact back to its source — not just that you turned in a file.

Already have a finished report? Evaluate runs it against 407 published rules and hands you an Evaluation Report — a quick second look before you deliver. Assemble is the one most appraisers reach for day to day.

Two ways to work

North Star has two products, and both are live. Assemble is the main one — the day-to-day way most appraisers build a workfile, where the tamper-evident record does the most for you. Evaluate is the quick check for a report you've already finished.

Assemble · the main product · $99 per assignment

Build a new appraisal workfile with proof of every source.

Open an assignment, pay to activate, then upload your source files. North Star reads them — including scanned pages — and records where each fact came from. When you seal the workfile, that record proves you can trace every fact back to its source.

What the seal proves — and what it doesn't

The record proves your report was checked — not that everything in it is correct. That difference matters, both for what you can confidently tell a lender or attorney and for what we would never claim on your behalf.

What the seal proves

The exact workfile you sealed, down to the last detail — change a single character later and it no longer matches.
The exact time it was sealed, recorded in the record and locked into the chain.
The exact rules applied, including which version and which state.
The exact results the check produced, the same every time.
That North Star sealed it — proof the record came from us.
That nothing was changed after the fact — each record is linked to the one before it, so altering any past record is caught the next time it's confirmed.

What the seal does not prove

That your report is accurate. If the information going in is wrong, the seal won't fix it.
That your value is correct. The rules check the work against the requirements, not your opinion of value.
That the condition you saw matches what's written. If the report says C3 and the property is really C5, the check still passes the condition rule.
That your comparable-sale data is accurate. MLS records, deeds, and sale histories are taken from your report as you entered them.
That the report “passes” any standard outside the 407 rules we check.
That the check is legal advice or a professional opinion. North Star is a tool. Use it that way.

What's in the rule library

407 rules across 15 catalogs, covering residential appraisal in two states (WA + OR). Each rule is written from a published public source and locked to the version used on every record, so you can trace it back to the statute, handbook, or guide it comes from.
