Getting your credit mortgage-ready in 12 months, month by month

The credit file a mortgage underwriter reads next year is mostly being written now. Every payment you make this month will still be on it. An inquiry you trigger today will still count in your score for most of that year. A card you close this spring will change your utilization math by summer.

Twelve months is a useful runway for that reason. Nothing magic happens at a year; it just lines up with how long FICO counts hard inquiries, and with the “last 12 months” lens several loan programs use when they judge recent payment history.

The year at a glance

Twelve months out: see what the lender will see

Pull your reports from all three bureaus at AnnualCreditReport.com. The FTC says you can check each one once a week for free, so there’s no reason to ration them. Read every account, not only the negative ones: wrong balances, accounts that aren’t yours, and late payments you didn’t make all count against you.

The score in your banking app is a useful trend line but probably not your mortgage score. Lenders use older FICO versions from each bureau, and your free score and a lender’s score can differ, sometimes by a wide margin. What matters is your middle score of the three, and your co-borrower’s. The middle score rule explains how lenders pick it and why two of your three scores have to clear any cutoff.

If something is wrong, dispute it now. Under 15 U.S.C. 1681i, a bureau generally has 30 days from receiving your dispute to reinvestigate, extendable by up to 15 days if you send new information during that time. Starting early also keeps disputes out of the way later. Fannie Mae’s Desktop Underwriter first evaluates a file including disputed accounts, and if that doesn’t produce an approval, the lender has to investigate them. If a disputed account is accurate and yours, the loan can’t be delivered as a DU loan at all. Read what not to dispute before a mortgage before you file anything.

Months 12 to 10: protect your payment record

Payment history is the largest piece of a FICO Score, 35% for the general population per myFICO. Set every account to autopay at least the minimum, then pay more by hand when you can. A 30-day late reported this month would still be on every report the lender pulls next year, and it would be the freshest negative item in the file.

Loan programs care about the recent record specifically. VA’s underwriting regulation, as one example, says satisfactory credit is generally considered reestablished after 12 months of satisfactory payments following the last derogatory item. Other programs and lenders apply their own versions of the same idea, so a clean final year is worth protecting even if older history is rough.

Think before you pay a collection. Paying one doesn’t remove it from your report, and the classic FICO versions mortgage lenders use still count paid collections. Whether to pay, settle or leave an account alone depends on the loan program and how the lender will count it in your debt ratios. Read should you pay a collection account, then ask a loan officer before sending money.

Months 9 to 4: bring card balances down

Amounts owed make up 30% of a FICO Score, and myFICO says using a lot of your available credit “may indicate that you are overextended.” Unlike a late payment, a high balance has no long memory in the classic FICO versions most mortgage lenders still use: when the reported balance drops, the score reflects it. Models that use trended data, such as VantageScore 4.0 and FICO 10T, also look at how balances moved over time, which is one more reason to start early. That makes card balances the part of your score you can actually move this year.

Example: you have three cards with $15,000 in total limits and $9,000 in balances, which is 60% utilization. If you put $833 a month toward them for nine months, that’s $833 x 9 = $7,497, leaving $1,503, or about 10% of your limits. (This ignores interest, which slows the real payoff. Pay the highest rate first if the cards differ.) Lower balances also cut the minimum payments counted in your debt-to-income ratio, which affects how much house you qualify for.

The utilization planner can map a payoff like this against your actual limits.

Two things to avoid during these months:

• Opening new credit. myFICO says opening several accounts in a short time “represents a greater risk,” and hard inquiries stay on your report for two years while counting in FICO Scores for one. That includes store cards offered at checkout and a new car loan.
• Closing old cards. Closing a card removes its limit from your utilization math, so the same balances become a higher percentage. Keep paid-off cards open unless they carry an annual fee you can’t justify.

Months 3 to 1: control the snapshot

The scores a lender pulls in this window are the ones you’ll be approved and priced on, so timing matters now. Most card issuers report the balance from your statement, not your payment due date. Paying a card down a few days before its statement closing date lowers the balance that gets reported. Paying down balances before an application covers the timing in detail.

When you’re ready to compare lenders, do it inside one short window. FICO groups mortgage inquiries made within a shopping period into one: any 45-day span for newer versions, any 14-day span for older ones, and it ignores those inquiries for the 30 days before scoring. The classic mortgage scores are older FICO versions, so shopping within 14 days is the cautious plan. The rate shopping guide explains how the windows work.

From application to closing: change nothing

Once you’ve applied, keep your credit exactly as the lender saw it. Don’t open accounts, co-sign for anyone, finance furniture, or let a payment slip. The CFPB notes that even a locked rate can change if your application changes, including your credit score. Keep paying every bill on time and keep card balances where they were.

If something unexpected shows up on your report during this stretch, call your loan officer before you dispute it or pay it. Quick fixes made in the last weeks are the ones most likely to stall a file.
