Avoid unnecessary new credit, but do not skip mortgage rate shopping: the Consumer Financial Protection Bureau (CFPB) says multiple mortgage checks within 45 days are recorded as a single inquiry under its general guidance. None of these steps guarantees a particular score increase, rate, or approval.
Start with your credit reports, not just one score
A credit report is the record of your credit accounts and payment history; a credit score is a calculation based on information in that report. You can have several scores because bureaus, scoring models, products, and calculation dates differ. A score displayed by a free app may not be the score a mortgage lender uses. Lenders commonly consider credit scores and reports, but their practices vary. The CFPB explains these differences in its homebuying resources and its guidance on what happens when a mortgage lender checks your credit.
Check your reports before you are deep into home shopping, leaving time to investigate errors. Looking at your own reports or scores does not hurt your score. The CFPB’s statement is direct: “When you check your own credit — whether you’re looking at your credit report or credit scores — the credit reporting companies don’t treat it the same as a lender making an inquiry.”
Find and dispute report errors
Review every report available to you. Check for accounts you do not recognize, late payments that are incorrectly reported, inaccurate account statuses, duplicate entries, and mistakes in your personal information. A genuine reporting error can be disputed; an accurate negative item cannot simply be removed because you are preparing to apply for a mortgage.

If you find an error, the CFPB advises contacting both the credit bureau and the company that supplied the information. Explain what is wrong and include copies of supporting documents. Keep copies of your dispute and any responses. See the CFPB’s instructions for disputing a credit report error for the process and current report-access information.
Build the habits most likely to help
Pay every bill on time
Payment history is an important factor in credit scores. Pay bills by their due dates; if you have fallen behind, bring the account current and continue paying on time. The CFPB identifies on-time payments as having the greatest impact among its basic credit-improvement tips, but the effect on an individual score depends on that person’s credit history and scoring model.
Reduce revolving balances where feasible
Credit-card balances matter in relation to available limits. The CFPB says experts advise using no more than 30% of total credit limits. Treat that as general guidance, not a guaranteed scoring threshold or a universal mortgage-lender rule. Paying down balances can help your credit profile, but no particular percentage guarantees a score change.
Avoid unnecessary new credit
As a mortgage application approaches, avoid opening several new accounts, taking out an avoidable auto loan, or making large credit purchases if you can. New applications and higher balances can affect your credit profile. Do not automatically close unused cards: the CFPB warns that closing a card can hurt in some circumstances and advises against closing unused cards unless they carry an annual fee.
How early should you check, and should you wait to apply?
Check well before you plan to buy so there is time to review reports, submit disputes, and work on balances and payment habits. The CFPB says people with at least six months before buying may have time to improve their scores and potentially get a better rate. That is a planning horizon, not a promise of a particular point gain or a required waiting period.
Deciding whether to apply now or wait depends on more than a score. Consider your actual loan options, report accuracy, debts, savings, income, and timeline. A lender’s decision can also reflect assets, debt, and other factors beyond the score. If you are unsure how to proceed, a HUD-approved housing counseling agency may help you review your reports and consider your options; it cannot guarantee approval or a score increase.

Applying for a mortgage involves a credit check. Under the CFPB’s guidance, multiple mortgage credit checks within 45 days are recorded on your report as a single inquiry. This is a general rule described by the CFPB, not a guarantee for every scoring model or circumstance; unrelated credit applications may still add inquiries.
Compare at least three mortgage offers. Look beyond the interest rate to the loan term, down-payment assumptions, monthly payment, points, fees, any payment adjustments on an adjustable-rate loan, and total costs over time. The CFPB provides a mortgage-offer comparison tool to help evaluate written offers.

Use score ranges as context, not cutoffs
The CFPB says borrowers with scores in the mid-to-high 700s or above generally receive the lowest rates, while people below 620 generally have trouble qualifying. These are broad patterns, not universal eligibility rules: outcomes depend on the loan type and lender, and the score a lender uses may differ from the one you see. A score is only one part of a mortgage decision.
