How to Get Mortgage-Ready in 12 Months: A Month-by-Month Credit Plan
Key Takeaways
- Mortgage lenders pull Equifax, Experian and TransUnion and qualify you on the middle score, so all three reports have to be clean.
- Months 1 to 2 are for pulling all three reports and disputing every error; under the Fair Credit Reporting Act the bureaus generally must investigate within 30 days.
- Payment history is the single largest FICO factor at about 35 percent, so the on-time streak you start this month is the one an underwriter reads next year.
- Amounts owed is about 30 percent of the score and has no memory: get every card under 30 percent of its limit, then push toward single digits.
- In the final 90 days open no new credit, co-sign nothing, keep your job, and leave the down payment sitting in one account so deposits are easy to source.

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 | What you do | Why it matters |
|---|---|---|
| 1 to 2 | Pull all three credit reports, dispute every error, start autopay on everything | Lenders qualify you on the middle of three scores, and the bureaus generally must investigate a dispute within 30 days |
| 2 to 8 | Get every card reporting under 30 percent of its limit, then push toward single digits, and close nothing | Amounts owed is about 30 percent of a FICO score and has no memory, so it is the fastest lever you control |
| 3 to 9 | Verify collections before paying, ask about goodwill on an isolated late, and track program waiting periods | Requirements differ by loan program, and paying an old collection does not always help the score |
| 6 to 12 | No new credit applications, no co-signing, keep the job, and season the down payment in one account | Hard inquiries and new accounts raise underwriter questions, and large unexplained deposits need paper trails |
| 12 | Confirm the middle score clears your loan type, balances report low and every dispute is resolved, then get pre-approved | Approvals die between pre-approval and closing more often than buyers expect |
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.
FAQ
How long does it take to get mortgage-ready?
Most buyers with fixable issues — high balances, report errors, thin history — see meaningful progress in 6–12 months. Major derogatories like bankruptcy or foreclosure run on program waiting periods of roughly 2–7 years.
Should I pay off collections before applying?
Verify accuracy first, then ask your loan officer — requirements differ by program, and paying an old collection doesn't always help your score. Don't pay reflexively.
Should I close old credit cards first?
No. Closing cards raises your utilization and can shorten your average account age. Keep them open with low balances.
