There's no trick in this plan. Mortgage underwriting rewards exactly two things: a credit file that's accurate, and behavior that's been boring for a while. Twelve months is enough time to deliver both — and if your credit is already decent, the same sequence compresses into six.

Months 1–2: See what lenders will see, then fix the errors

Pull all three reports. Mortgage lenders pull Equifax, Experian, and TransUnion and qualify you on the middle score, so one bad report can set your rate. Get the free reports at AnnualCreditReport.com, and if you want scores plus ongoing tracking in one dashboard, a service like SmartCredit shows all three bureaus side by side and monitors changes while you work the rest of this plan.

Dispute everything that's wrong. Common finds: accounts that aren't yours, wrong balances or limits, late payments you didn't make, paid collections still showing unpaid, and duplicate collection entries. Under the Fair Credit Reporting Act, bureaus generally must investigate disputes within 30 days. Dispute with each bureau that shows the error, in writing, with documentation.

Start the on-time streak. Payment history is the single largest factor in your FICO score (about 35%). Autopay the minimum on everything today — the streak you start this month is the one an underwriter reads next summer.

Months 2–8: Pay down utilization — the biggest lever you control

After payment history, the amount you owe relative to your limits (about 30% of a FICO score) is the heaviest factor — and unlike late payments, it has no memory. Get every card reporting under 30% of its limit, then push toward single digits. The mechanics, timing tricks, and which cards to pay first are covered in the utilization guide.

While you're at it: don't close anything. Closing old cards shrinks your available credit and raises utilization. Cut the card up if you must, but leave the account open.

Months 3–9: Handle derogatories deliberately, not reflexively

• Collections: verify accuracy first — inaccurate or unverifiable collections are dispute material. For legitimate ones, ask a loan officer before paying anything old; requirements differ by loan program, and paying an old collection doesn't always help the score.
• Late payments: these age out of significance gradually. If you have a single late on an otherwise clean account, a goodwill request to the creditor sometimes works — no guarantee, but it's a stamp and a page.
• Bankruptcies and foreclosures: these run on program waiting periods (commonly 2–4 years for FHA, up to 7 for some conventional scenarios). If you're inside a waiting period, your 12 months is about building the cleanest possible file for the day it ends.

Months 6–12: Go quiet

• No new credit applications. Hard inquiries and new accounts drag on your score and raise underwriter questions. The car can wait until after closing — a new car loan before a mortgage application is one of the classic self-inflicted denials.
• No co-signing. Their loan becomes your debt-to-income problem.
• Stabilize your cash. In the final 90 days, lenders will want bank statements. Large unexplained deposits require paper trails; keep your down-payment money parked in one account and let it sit ("seasoned" money is easy money).
• Keep the job. Underwriters verify employment right up to closing day.

Month 12: Check your numbers before a lender does

Before you apply, confirm three things: your middle credit score clears the target for your loan type (see the score requirements by loan type), your card balances are reporting low, and every dispute from month 1 is resolved on all three reports. Then get pre-approved — and once you are, read what not to do before closing, because approvals die between pre-approval and closing more often than you'd think.
