To improve your credit score for a mortgage, do four things: pay each credit card down before its statement closes, dispute any errors on your three credit reports, pay every bill on time, and apply for no new credit. Lower balances can count within one billing cycle. Corrected errors and a clean payment record take longer, so give yourself several months before you apply.

Know this before you start. A 30-point jump in a week is possible only through a rapid rescore, which your lender orders. It works only when the points come from a fixed error or a balance you have already paid down.

What you need

  • Your reports from Equifax, Experian and TransUnion

    Pull them through AnnualCreditReport.com. You need all three, because lenders do not all see the same data.

  • The limit and statement closing date for every card

    Card issuers usually report your balance as of the statement date, not the due date.

  • Cash to get each card under 30% of its limit, ideally under 10%

    On a $10,000 limit, that means under $3,000, and ideally under $1,000.

  • Proof for any error you plan to dispute

    Statements, payment confirmations, or a letter from the creditor.

  • A target score

    FHA requires 580 with 3.5% down. Most conventional lenders require 620. Lenders' own overlays often add 20 to 40 points on top of those minimums.

If you are not sure which loan you are aiming for, the bars are set out for the FHA 580 cutoff and for conventional loans. Small gains are still worth chasing above the minimum. In Experian's September 2026 data for a $350,000 loan, a 30-year fixed averaged 7.61% at a 620 FICO score and 6.93% or lower at 760 and above.

The steps, in order

  1. Pull all three reports

    Read every line. Look for accounts you do not recognize, late payments you made on time, and wrong balances. In an FTC study, 26% of participants found at least one error. It has worked when you have a written list of every wrong entry, or you have confirmed there are none.

  2. Dispute each error with the bureau that reports it

    Attach your proof to each dispute. FICO advises doing this months before you apply, so corrections land in time. It has worked when the bureau updates or removes the entry.

  3. Turn on autopay for every bill

    Payment history is 35% of a FICO score, the largest single factor. Set autopay on cards, utilities, student loans and medical bills. It has worked when every account shows as paid on time each month.

  4. Pay each card down before its statement closes

    Utilization is 30% of a FICO score, and it has no memory. Once a lower balance is reported, that part of your score improves. It has worked when your next statement shows the lower balance.

    One billing cycle
  5. Leave every existing card open

    Closing a card removes available credit, which pushes your utilization up. Keep unused cards open and keep their balances at zero.

  6. Stop applying for new credit

    A single inquiry costs only a few points, but that can be enough to drop you below a lender's minimum. Inquiries affect FICO scores for 12 months. A new card can also cut your average account age roughly in half. Hold off on large purchases until after closing, too.

  7. Ask your loan officer for a rapid rescore if you are a few points short

    A rapid rescore updates the bureaus with your paid-down balances or corrected errors. It can add 20 to 100+ points in 3 to 7 business days. The lender pays the $25 to $40 fee per file, per bureau. You cannot order one yourself.

    3 to 7 business days

When the score will not budge

You most likely paid after the statement closed, so the old balance was reported. Wait for the next statement. If you are already working with a lender, ask for a rapid rescore instead.

If the late payment is accurate, it stays on your report for seven years, and a rapid rescore cannot remove it either. Keep every payment current from here on, which limits further damage.

No. The inquiry stops affecting your FICO score after 12 months. The lower average account age improves as the account ages. Do not open anything else before you close on the home.

None of the sources we checked gave a figure or a timeline for how much it helps a mortgage score, so we have left it out of the steps.

Be cautious of anyone promising dramatic, fast improvements for an upfront fee. The only legitimate fast route is a rapid rescore, and your lender pays for that.

Once the new score is reporting

Now get quotes. Under the rate-shopping rule, several mortgage credit pulls within a 45-day window count without extra damage to your score, so compare lenders inside that window. Use the best quote to start your mortgage pre-approval.
