What lenders look for before they approve a mortgage
Mortgage lenders check three things: your credit score, your payment history on the credit report itself, and your debt-to-income ratio. A score of 620 is the minimum for a conventional loan with the Federal Housing Administration (FHA), but most lenders want 640 or higher. The score alone does not tell the whole story — a lender will also look at whether you have late payments, collections accounts, or charge-offs on your report, and how much debt you already carry compared to your income.
The good news is that credit damage is not permanent. Late payments age off your report after seven years. Collections accounts stop affecting your score after they are paid, though the account stays on your report. Charge-offs (accounts the creditor gave up on) also age and lose power over time. What matters most to a mortgage lender is the pattern: if your late payments are recent, the lender sees ongoing risk. If they are old and your recent history is clean, the lender sees someone who recovered.
Before you start any repair work, order your credit report from all three bureaus — Equifax, Experian, and TransUnion — at annualcreditreport.com, which is the only site the Federal Trade Commission (FTC) recognizes as official. Check for errors: accounts that are not yours, payments marked late that you made on time, or balances that are wrong. Dispute errors directly with the bureau that reported them, and the bureau must investigate within 30 days.
Key Takeaways
- Mortgage lenders require a credit score of at least 620, though 640 or higher gives you better terms and more loan options.
- Late payments hurt your score most when they are recent; payments older than two years matter far less to a lender's decision.
- Paying down existing debt lowers your debt-to-income ratio and raises your score, often faster than waiting for old accounts to age off.
- Errors on your credit report can be disputed for free directly with the credit bureau, and corrections can raise your score within weeks.
- Building a history of on-time payments takes months, so starting the repair process six to twelve months before you plan to buy gives you the most options.
Fixing errors and removing accounts that should not be there
Errors are common. A payment might be reported late when you paid on time. An account might appear twice. A debt might be listed under the wrong name or Social Security number. Each error costs you points, and removing them is free.
Start by getting your report from annualcreditreport.com. Read it line by line. For each error, write to the bureau that reported it — Equifax, Experian, or TransUnion — with a letter that names the account, explains what is wrong, and includes a copy of proof (a bank statement showing you paid on time, a letter from the creditor, or a court document). Send it certified mail so you have proof of delivery. The bureau must investigate within 30 days and tell you the result. If the error is confirmed, it comes off your report when ready.
If a debt was sold to a collection agency and the original creditor still reports it, you can dispute the duplicate. If a collection account is paid but still showing as unpaid, dispute it. These disputes often succeed because the bureau cannot verify the old information, and when they cannot verify it, they must remove it.
Paying down debt to lower your debt-to-income ratio
Your debt-to-income ratio is the total of all your monthly debt payments divided by your gross monthly income. Most lenders want this below 43 percent. If you earn $5,000 a month and your car payment, credit cards, student loans, and other debts total $2,200 a month, your ratio is 44 percent — too high for most mortgages.
Paying down debt raises your score and lowers your ratio at the same time. The fastest way is to target high-balance accounts first. If you have a credit card with a $8,000 balance at 22 percent interest and another with a $2,000 balance at 18 percent, paying $500 toward the $8,000 card does more for your score than paying the smaller card off entirely. Your score improves when the ratio of your balance to your credit limit drops — this is called your utilization rate. Keeping balances below 30 percent of your limit is ideal; below 10 percent is excellent.
Do not close paid-off accounts. Closing an account removes available credit from your total, which raises your utilization rate and lowers your score. Instead, keep the account open and use it occasionally — a small charge every few months, paid in full — to show active, responsible use.
Building a history of on-time payments
Payment history is 35 percent of your credit score. One late payment can drop your score 100 points or more, but one on-time payment raises it only a few points. This means you need months of clean history to recover from recent damage. If you had a late payment six months ago, you need at least six more months of on-time payments before a lender will see you as low-risk.
Set up automatic payments for at least the minimum on every account — credit cards, loans, utilities, phone bills. Lenders see utility and phone payments on your report if you pay late, so these count. If you have missed payments in the past, call the creditor and ask about a goodwill adjustment: some creditors will remove a single late payment from your report if you have been current since then and ask politely. This is not may provide, but it costs nothing to request.
If you have no credit history at all — no credit cards, no loans, no payment record — you can build one by becoming an authorized user on someone else's account with a clean payment history, or by opening a secured credit card. A secured card requires a cash deposit (usually $200 to $2,500) that becomes your credit limit. Use it for small purchases and pay the full balance every month. After six to twelve months of perfect payments, you can graduate to a regular card.
Timing your mortgage process to maximize your score
Your score changes constantly as new information hits your report. A single on-time payment might raise it 5 to 10 points. Paying down a credit card balance by $2,000 might raise it 20 to 50 points. The gains are not linear — the first points are hardest to earn, and the last points to reach 750 or higher take months.
If you are planning to buy a house, start your repair work six to twelve months before you plan to explore for a mortgage. This gives you time to dispute errors, pay down balances, and build a clean payment history. The month before you explore, stop opening new accounts and making large purchases. Each new account or hard inquiry (when a lender checks your credit) drops your score slightly, and lenders see multiple inquiries as a sign of financial stress.
When you are ready to shop for a mortgage, multiple lenders will pull your credit within a short window — usually two weeks. These inquiries count as a single inquiry for scoring purposes, so do not space them out. The lender will also order your full credit report and verify your income and employment, so have recent pay stubs, tax returns, and bank statements ready.
Accounts that are too old or too damaged to repair quickly
Some damage takes time to fade. A charge-off (an account the creditor wrote off as uncollectible) stays on your report for seven years from the date of first delinquency, but its impact on your score weakens after two years. A collection account does the same. A bankruptcy stays for seven to ten years depending on the type.
If you have old damage that you cannot remove, focus on what you can control: paying down current debt, making all current payments on time, and disputing any errors. Lenders understand that people have rough patches. What they want to see is that you recovered. A mortgage process with a bankruptcy from eight years ago, zero late payments in the last two years, and a debt-to-income ratio below 43 percent will often be approved. The same process with a bankruptcy from two years ago will usually be denied.
If you have a collection account that is still unpaid, paying it does not remove it from your report, but it does change the status to "paid collection." A paid collection hurts your score less than an unpaid one, and some lenders weight it less heavily. Before you pay, ask the collection agency in writing whether they will remove the account entirely if you pay in full — some will, and this is called a "pay to delete." Get the agreement in writing before you send money.
When to work with a credit counselor versus doing it yourself
You do not need to pay anyone to repair your credit. Disputing errors, paying down debt, and making on-time payments are all free. However, a nonprofit credit counselor can help you create a budget, negotiate with creditors, or set up a debt management plan if you are overwhelmed.
Look for a counselor certified by the National Foundation for Credit Counseling (NFCC) or the Financial Counseling Association (FCA). These organizations require their counselors to be trained and their services to be free or low-cost. Avoid for-profit credit repair companies that promise to remove negative information or raise your score by a specific amount — these promises are illegal, and the companies often charge hundreds of dollars for work you can do yourself.
A debt management plan (DMP) is a formal agreement where a counselor negotiates with your creditors to lower your interest rates and consolidate your payments into one monthly amount. A DMP appears on your credit report and can actually lower your score temporarily, but it shows lenders that you are taking action. If you enter a DMP, most lenders will not approve a mortgage until you have completed it or at least made 12 to 24 months of on-time payments under the plan.
Frequently Asked Questions
How much will my score go up if I pay off a credit card?
It depends on the card's balance and your total credit limits. Paying off a card that has a $5,000 balance when your total limits are $10,000 might raise your score 30 to 80 points because you dropped your utilization from 50 percent to lower. Paying off a card with a $500 balance when your total limits are $50,000 might raise it only 5 to 15 points. The effect is largest when you bring high-balance cards below 30 percent of their limit.
Will a late payment from three years ago hurt my mortgage process?
It will be visible on your report, but it will hurt far less than a recent late payment. Most lenders focus on the last two years of history. If you have made all payments on time since that late payment three years ago, many lenders will overlook it, especially if you can explain what happened (a job loss, medical emergency, or other one-time event). Recent clean history matters more than old damage.
Can I remove a collection account by disputing it?
You can try. If the collection agency cannot verify the debt or if the account is past the statute of limitations in your state, the bureau must remove it. However, if the debt is valid and the agency can verify it, the dispute will fail. Your best option is to negotiate a pay-to-delete agreement in writing before you pay, or to pay it and let time reduce its impact.
How long does it take to build credit from scratch?
You can reach a score of 620 to 640 in six to nine months with a secured credit card or as an authorized user on a clean account, assuming you make every payment on time and keep balances low. Reaching 700 or higher takes twelve to eighteen months of perfect history. Mortgage lenders will work with scores as low as 620, but you will get better interest rates and terms at 680 or above.
Should I pay off old collections accounts before I explore for a mortgage?
Paying an old collection account does not remove it from your report, but it changes the status to "paid," which lenders view more favorably than unpaid. However, paying it can also restart the clock on how long it stays on your report in some cases. Before you pay, ask the collection agency whether they will agree to remove it entirely (pay-to-delete) or straightforward mark it paid. Get any agreement in writing.
