Mortgage lending has used the same credit scoring models for decades. The versions of FICO that most lenders pull for a home loan are older than some of the people applying for one.
That is finally changing. Federal housing regulators have approved two newer models, VantageScore 4.0 and FICO 10T, for use on loans backed by Fannie Mae and Freddie Mac. The shift is real, but it is also slower and less dramatic than the headlines suggest. Here is a calm read on what it means if you are planning to buy in El Paso in the next year or two.
What is actually changing?
Two newer scoring models are being allowed into mortgage underwriting.
Regulators ordered the mortgage giants to accept VantageScore 4.0 in mid 2025, and in April 2026 both VantageScore 4.0 and FICO 10T were approved for use. VantageScore 4.0 is already live with a limited group of lenders, with the rollout expanding through 2026. Once the transition is fully in place, lenders will deliver both scores with each loan they sell to Fannie or Freddie.
For borrowers, the practical meaning is that the score a mortgage lender sees will eventually reflect newer math than the classic models built years ago.
When will this reach your actual loan application?
Probably later than you think, and this is worth being honest about.
The classic FICO models still score most mortgage applications today. VantageScore 4.0 is available only through a limited lender rollout so far. Fannie Mae released the historical data lenders need for FICO 10T in July 2026, but the actual adoption date for 10T in mortgage underwriting has not been announced and is still pending as of this writing. Anyone who tells you a firm date is guessing.
The realistic picture: the impact broadens through 2026 and 2027. If you are applying this summer, your lender is most likely still pulling the classic scores. If you are twelve to eighteen months out, the newer models become much more likely to matter to you.
What is trended data, and why does it change the advice?
This is the biggest substantive difference, and it rewards a habit instead of a snapshot.
The classic models look at your balances at a single moment. Both new models look at roughly 24 months of history: whether balances are moving down, staying flat, or growing, and whether you pay in full or carry a balance from month to month. Two people with identical utilization today can score differently if one has been steadily paying balances down and the other has been letting them build.
That changes the preparation advice. Paying a card down to a low balance the month before an application still helps, but under trended data the pattern of the past two years is itself part of the score. Someone who consistently pays more than the minimum, and ideally pays statements in full, builds a stronger profile than someone who sprints at the finish line.
Does rent finally count for a mortgage?
Increasingly, yes, and for renters this may be the most useful change.
Both VantageScore 4.0 and FICO 10T natively score rent, utility, and phone payment data when it appears on a credit report, and both can score thinner files that the classic models could not. For households that have paid rent on time for years without ever seeing credit for it, that history can start working in their favor, but only if the rent actually reaches a bureau. Most landlords do not report it, so it usually takes a rent reporting service or a landlord who participates in one.
If rent is the strongest line in your financial life, it is worth getting it onto the record before the new models reach your lender.
Is it true that mortgages will only check two bureaus now?
No. That proposal was shelved.
There was a plan to move mortgage lending from three credit reports to two. It did not go forward. The tri-merge report, which pulls all three bureaus, remains the standard for mortgage applications. That means an error sitting on any one of your three reports can still affect your approval, so all three files need to be clean, not just the one you happen to check.
What should a buyer do this year?
The steady moves have not changed, and the new models mostly reward them more.
Pull all three reports and deal with inaccuracies now, while there is no application on the clock. Keep every payment on time. Pay revolving balances down over months rather than in one pre-application scramble, because the downward trend itself will eventually be scored. If you rent, look into getting that history reported. And if a mortgage is more than a year away, you have time to let all of this compound, which is a genuinely good position to be in.
