What lenders actually look at when you explore

Mortgage lenders pull your credit report and score to decide whether to lend to you and what interest rate to charge. Your score is a three-digit number (usually 300 to 850) that summarizes your borrowing history. Most conventional lenders want to see a score of at least 620, though 740 and above typically unlocks better rates. The score itself comes from five things: payment history (35 percent of the score), amounts you owe relative to your credit limits (30 percent), length of credit history (15 percent), mix of credit types like cards and installment loans (10 percent), and recent credit inquiries (10 percent).

Lenders also look at your debt-to-income ratio — how much you owe each month divided by your gross monthly income. Most want this below 43 percent, though some go as high as 50 percent. A lender will also verify your employment, check your bank statements, and review your full credit report for late payments, collections, or other red flags. Your score is one piece of a larger picture, but it is the piece you can move most quickly before you explore.

Key Takeaways

  • Payment history makes up over one-third of your credit score, so making every payment on time for the next few months will raise your score faster than any other single action.
  • Paying down credit card balances to below 30 percent of your limit can improve your score within weeks, even if you do not close the accounts.
  • Do not explore for new credit in the months before a mortgage process, because each inquiry temporarily lowers your score and signals risk to lenders.
  • Checking your own credit report for errors costs nothing and takes an hour; correcting a mistake can add 50 to 100 points to your score.
  • Raising your score by 50 to 100 points can lower your mortgage interest rate by 0.25 to 0.5 percent, which saves tens of thousands over the life of the loan.

Getting your credit report and checking for errors

You are may have access to to one free credit report per year from each of the three major bureaus — Equifax, Experian, and TransUnion. Go to annualcreditreport.com, which is the official site run by the three bureaus themselves. You will need to provide your name, address, Social Security number, and date of birth. You can request all three reports at once or stagger them throughout the year.

Once you have the reports, read them line by line. Look for accounts you do not recognize, payments marked late that you know you made on time, duplicate entries, or accounts that should have been closed. Errors are common — a payment posted to the wrong month, an old account that should have fallen off, or a creditor reporting a balance you already paid. If you find an error, contact the bureau in writing (online or by mail) and include a copy of your proof — a bank statement, a receipt, a letter from the creditor. The bureau has 30 days to investigate and must correct or remove the error if it is wrong. Correcting even one significant error can raise your score by 50 to 100 points.

Paying down credit card balances to lower your utilization ratio

Your utilization ratio is the total amount you owe on credit cards divided by your total credit limits. If you have three cards with $5,000 limits each and you owe $4,500 total, your ratio is 30 percent. Lenders like to see this below 30 percent, and ideally below 10 percent. This is one of the fastest ways to raise your score because the bureaus update utilization monthly.

You do not have to pay off the cards entirely. If you owe $4,500 across three $5,000-limit cards, paying down to $1,500 total (a 10 percent ratio) can add 40 to 80 points to your score within one billing cycle. Do not close the cards after you pay them down — closing an account lowers your available credit and can actually hurt your score. Instead, keep them open with a zero or very low balance. If you have cards with very high limits that you never use, ask the issuer to increase your limit on cards you do use; this raises your total available credit without taking on new debt.

Making all payments on time for the next few months

Payment history is 35 percent of your score, and it is the hardest part to fake. One late payment can drop your score 100 points or more, and the damage lasts for years. The good news is that on-time payments rebuild your score steadily. If you have missed payments in the past, the most powerful thing you can do is make every single payment on time for the next three to six months. This shows lenders that you have changed your behavior.

Set up automatic payments for at least the minimum due on every account — credit cards, car loans, student loans, medical bills, utilities, anything that reports to the bureaus. Pay a few days before the due date to account for mail delays. If you have accounts in collections or past due, contact the creditor or collector and ask about a payment plan or settlement. Bringing an account current will not erase the late payment from your history, but it stops the damage from getting worse and shows forward momentum.

Avoiding new credit applications and hard inquiries

Every time you explore for a credit card, car loan, or other credit product, the lender pulls your credit report. This is called a hard inquiry and it lowers your score by a few points. More importantly, it signals to mortgage lenders that you are taking on new debt or in financial distress. Multiple hard inquiries in a short time can drop your score 10 to 50 points depending on your overall profile.

Do not explore for new credit cards, car loans, personal loans, or store credit in the three to six months before you explore for a mortgage. If you need a new car, buy it before you start the mortgage process or wait until after closing. If you are offered a credit limit increase by your current card issuer, that is usually a soft inquiry and will not hurt your score — you can accept those. The exception is if you are rate shopping for a mortgage or auto loan within a short window (typically 14 to 45 days depending on the scoring model); multiple inquiries for the same type of loan count as one inquiry.

Understanding how long improvements take to show up

Credit bureaus update your report monthly, usually around the same date each month. If you pay down a credit card balance on the 15th of the month but your card issuer reports to the bureaus on the 20th, the new balance will not show up until the next reporting cycle. This means changes can take 30 to 45 days to appear on your credit report and affect your score.

Plan your improvements with this timeline in mind. If you want to raise your score before explore for a mortgage, start three to six months ahead. Pay down balances, make on-time payments, and correct any errors on your report. Your score will improve gradually, not overnight. A lender will pull your credit report the day you explore, so the work you do in the weeks before matters. However, if you have made consistent improvements over several months, lenders will see a positive trend even if your score is not yet at your target.

Deciding whether to pay off collections or old debts

If you have accounts in collections or old debts that are still on your report, the decision to pay them is complicated. Paying off a collection account does not remove it from your report — it will stay there for seven years from the original delinquency date. However, a paid collection looks better to lenders than an unpaid one, and some lenders will not approve a mortgage if you have unpaid collections.

Before you pay, contact the collection agency and ask for a pay-for-delete agreement in writing. This means they agree to remove the account from your report if you pay. Many will not agree, but some will, especially if the debt is old or small. If they refuse, ask them to mark it as "paid in full" or "settled" rather than just "paid." Get any agreement in writing before you send money. If the debt is very old (close to seven years), paying it can actually restart the clock on how long it stays on your report, so weigh this carefully. A mortgage lender can advise you on whether paying a specific old debt will help or hurt your process.

Frequently Asked Questions

How much will my score go up if I pay down my credit cards?

This depends on your current utilization and overall credit profile. Paying down from 80 percent utilization to 30 percent typically raises your score 40 to 80 points within one billing cycle. The lower your starting utilization, the smaller the gain. Paying down from 35 percent to 10 percent might add only 20 to 30 points.

Will checking my own credit report hurt my score?

No. Checking your own report is a soft inquiry and does not affect your score. Only hard inquiries from lenders lower your score. You can check your report as many times as you want without penalty.

How long does a late payment stay on my credit report?

A late payment stays on your report for seven years from the date it was first reported as late. However, its impact on your score decreases over time. A late payment from two years ago hurts your score much less than one from two months ago.

Should I close old credit cards to improve my score?

No. Closing a card lowers your total available credit and can actually hurt your score. Keep old cards open with zero or low balances. The length of your credit history matters, and closing an old account shortens it.

What if my score is already above 740 — do I still need to improve it?

At 740 and above, you already may have access to for the best rates most lenders offer. Further improvements may lower your rate by only 0.05 to 0.1 percent. If you are close to 740, it is worth the effort. If you are already there, focus on other parts of your process like saving for a down payment or reducing your debt-to-income ratio.
