Suppose you hope to apply for a mortgage in a few months. Before comparing homes or filling out applications, take time to see what your credit reports say. A credit report lists account and payment information. A credit score is a number calculated from information in a report. Lenders may consider both when deciding whether to approve a loan and what interest rate to offer.

Know the difference between checking and applying

Looking at your own credit reports or scores does not hurt your scores. A lender’s check is different. When a lender checks your credit as part of an application for new credit, the check is generally recorded as a hard inquiry. An inquiry is a note on your credit file that other lenders may see, and it can have a small negative effect on your scores. The Consumer Financial Protection Bureau explains mortgage credit inquiries and how rate shopping is treated.

A lender may also make a soft inquiry, such as when an existing lender reviews an account. Soft inquiries do not affect your score. If you are only asking a lender about rates, the lender cannot pull your credit report. Before you submit an application, ask whether it will trigger a hard inquiry. The CFPB describes when lenders may check credit, including during later stages of a mortgage process.

Read your reports before you apply

Start with the reports, not just a score number. Check the account names, balances, payment history, and other details for information you do not recognize or believe is wrong. An error may affect a score inappropriately. Finding a problem well before an application gives you time to look into it and use the relevant credit reporting company’s dispute process. The sources do not specify dispute steps or timelines, so check official consumer information for current instructions.

The Federal Trade Commission says free weekly credit reports are permanently available. You can use that access to review your reports on a recurring schedule rather than waiting until you are about to apply. Visit the FTC’s page on free weekly credit reports for details. After checking the reports, you can also obtain one or more scores and learn how scores are calculated. A score is a summary derived from report information, so checking a score alone will not show you every detail that may matter to a lender.

Understand what a mortgage lender may consider

Mortgage lenders generally look at credit scores alongside information in credit reports. Many use FICO scores and review scores from Equifax, Experian, and TransUnion, the three major credit reporting companies. The CFPB says lenders typically use the middle of those three scores to help determine the rate offered. A middle score is the one between the highest and lowest, not an average of all three.

That score is one part of the decision. A lender may also consider your credit history with that lender, existing debt, savings, total assets, and current income. Scores in the mid- to high-700s or above generally receive the lowest mortgage rates, but the sources do not give exact score cutoffs for particular offers. A score by itself cannot tell you whether you will qualify or what rate you will receive. Read the CFPB’s overview of how credit scores can affect a mortgage for more context.

A credit check may happen at more than one point. A lender can check credit to prepare a pre-approval, review an account, consider refinancing, or check again shortly before closing. Ask when the lender expects to check and which scores and reporting companies it uses. That helps you understand what a particular check is for without assuming that one score or report tells the entire story.

Shop for mortgage offers within the rate-shopping window

Comparing mortgage offers can involve more than one lender checking your credit. Multiple mortgage lender checks made within a 45-day window are recorded as a single inquiry, provided the last check falls within 45 days of the first. The CFPB notes that the small effect of an additional inquiry is usually outweighed by the potential savings from shopping around. You can compare pre-approvals and Loan Estimates within that window while keeping track of when the first lender check occurred.

For example, if you begin comparing lenders on a Monday, note that date and ask each lender when it plans to check your credit. The 45-day period is measured from the first check to the last, so a later check outside that span may not receive the same treatment. Ask lenders whether they expect to check again after the window and how that later check could affect your credit. Do not assume the first inquiry is the only one in the process.

Also be mindful of other applications while preparing for a mortgage. Applying for several new credit accounts in a short time may negatively affect your score. Opening a card, car loan, or other loan right before or during a mortgage process can add new account activity for a lender to consider. The general guidance is to apply for new credit only when needed, and to ask questions before an application if you are unsure what credit check it will involve.

Ask clear questions and verify unusual requests

Before applying, ask the lender: Will this application result in a hard inquiry? Which scores and credit reporting companies do you use? When might you check my credit again? If a later check occurs after the 45-day shopping window, what should I know about its effect? These questions can help you distinguish an early rate conversation from an application that leads to a credit check.

Keep personal information safe while you gather answers. Scammers sometimes impersonate organizations and use urgent or threatening messages to pressure people into sharing information. Verify a request through an official channel before sending personal or financial details. The FTC offers information about free credit reports and consumer protection concerns. Use official consumer pages for current report-access and dispute instructions, since the process and timing can depend on the issue.

A practical review does not guarantee approval or a particular score. It gives you a clearer view of the reports lenders may use, a chance to spot possible errors, and a better understanding of what questions to ask before an application. Even a short check of account details and inquiry timing can make the next steps less surprising.
