Most consumer credit-monitoring services (Credit Karma, Experian Free, the free score on your card statement) show you a FICO 8 or VantageScore 3 number. Mortgage underwriters do not use those numbers. They pull the FICO Classic suite — Equifax Beacon 5, TransUnion FICO 4, and Experian FICO 2 — which can differ from your consumer-facing score by 30 to 80 points. This tool gives you the TransUnion FICO 4 number for free.
The Free Mortgage FICO Score tool refreshes your TransUnion FICO 4 score monthly. FICO 4 is the score model most mortgage underwriters use when they pull TransUnion data through the tri-merge mortgage report. Seeing the FICO 4 number tells you what a lender is most likely to see — not what Credit Karma's VantageScore tells you.
The output is designed to be read by a human, not just by a machine. Each finding includes a plain-English explanation of why the item appears the way it does, which FCRA section or Metro 2 field is at issue, and what a reasonable next step would be — investigate, dispute, or leave in place.
Sign up with your name and basic identity verification (no credit card required for the score itself). The tool runs a soft inquiry with TransUnion, which does not affect your score. Your FICO 4 number appears immediately and refreshes monthly. Use the trend line to investigate whether dispute rounds, balance changes, and account-age increases are actually moving the mortgage-eligible score.
Pair the tool with the Credit1Solutions members portal Dispute Tracker so every action you take is logged in a single timeline. The send-and-log workflow in the DIY Kit will write back to the tracker automatically, which keeps the round-by-round evidence record clean if a matter eventually routes to the attorney network for FCRA / FDCPA review.
Credit1Solutions offers the FICO 4 score free because the gap between consumer scores and mortgage scores is one of the most damaging blind spots in personal finance. Consumers who think they have a 720 FICO 8 sometimes find out at the closing table that their FICO 4 is 670 and that the rate sheet they were quoted no longer applies. We would rather you know the real number months before you apply.
Credit1Solutions has been an attorney-backed credit-education company since 2006. BBB A+ accredited since 2015. Free tools exist to make it easy for consumers to investigate their files without committing to a plan up front. When you decide a paid plan makes sense, we are here — but the decision belongs to you.
The soft pull is invisible to other lenders — it is not the kind of inquiry that appears on the credit reports of third-party creditors. Your identity-verification data is encrypted at rest and is not shared outside the TransUnion data feed required to compute the score.
You can read the full Credit1Solutions privacy policy for the complete data-flow disclosure. We follow the CFPB and FTC guidance on consumer financial data and do not participate in data-broker resale.
