Reviewing your credit before buying a home gives you time to find errors, spot signs of identity theft, and understand what a lender may see. Checking your own credit reports does not lower your credit score.
You can request free reports from Equifax, Experian, and TransUnion through AnnualCreditReport.com. Because the information can differ among the three reports, review each one carefully.
This guide explains how to review your credit reports, correct inaccurate information, avoid actions that could affect your mortgage qualification, and protect your credit from fraud.
1. Review Your Credit Reports Early
Review all three credit reports well before you apply for a mortgage. The information reported by Equifax, Experian, and TransUnion may differ, so checking only one report could leave an error or unfamiliar account undiscovered.
Confirm that your name, addresses, accounts, balances, and payment history are accurate. Look for accounts you do not recognize, payments incorrectly reported as late, debts listed more than once, and information belonging to someone else.
Checking your own reports does not lower your credit score. Starting early gives you time to correct errors or respond to signs of identity theft before a lender reviews your credit.
2. Correct Errors Before Applying
If you find inaccurate or incomplete information, dispute it with both the credit bureau and the company that supplied the information. Include copies of documents that support your dispute and keep records of everything you submit.
Credit bureaus generally have 30 days to investigate, so do not wait until you are ready to apply for a mortgage. Starting early gives you time to resolve the problem and confirm that the correction appears on your reports.
3. Avoid Actions That Could Affect Your Credit
Pay bills on time and keep credit card balances as low as practical. Late payments, higher balances, and new debt can affect your credit score and mortgage options.
Before opening or closing accounts, financing a purchase, transferring balances, or paying down debt, ask your lender how the change could affect your credit and qualification.
4. Protect Your Credit From Identity Theft
If you find unfamiliar accounts or are concerned that someone could misuse your information, consider placing a credit freeze or fraud alert.
A credit freeze restricts access to your credit reports, making it harder for someone to open an account in your name. Freezes are free, do not affect your credit score, and must be placed with each credit bureau. Before a mortgage lender checks your credit, temporarily lift the freeze as directed by the lender.
I keep credit freezes in place at all three bureaus and temporarily lift them when a legitimate credit check is needed.
A fraud alert tells businesses to verify your identity before opening new credit in your name. You only need to contact one credit bureau, which must notify the other two. An initial fraud alert lasts one year, while an extended alert for identity-theft victims lasts seven years.
5. Know Which Credit Checks Affect Your Score
Reviewing your own credit reports does not affect your credit score. A mortgage lender’s credit check is a hard inquiry and may have a small, temporary effect on your score.
Do not let that prevent you from comparing lenders. Credit-scoring models generally treat multiple mortgage inquiries made within a short rate-shopping period as one inquiry for scoring purposes, although each inquiry may still appear on your credit reports.
Review Your Credit Before Buying a Home
Reviewing your credit reports early gives you time to correct errors, address possible fraud, and understand what a lender may see. When you are ready to apply, tell your lender about any credit freezes so they can explain when and how long to lift them.
Your credit is only one part of choosing a loan. You can also review how to compare mortgage options before applying for preapproval.
