Article Summary
A credit bureau is a company that gathers, maintains, and provides information to mortgage lenders about a home buyer's credit history.
Credit Bureau: Explained in Plain English
Credit bureaus, also called credit reporting agencies, collect and report on financial data from many sources, including banks, credit card companies, collection agencies, and government records.
Data collected by credit bureaus includes information about student loans, personal loans, and other loans; credit card usage and payment history; and records of bankruptcies or other negative financial outcomes.
Credit bureaus compile this data into credit reports, which lenders use to assess a home buyer's mortgage application and overall creditworthiness. Credit bureaus are responsible for maintaining accurate records but do not make lending decisions themselves.
When a first-time home buyer seeks pre-approval, the lender requests a credit report from one or more credit bureaus. However, because each bureau collects and reports data independently, the buyer's credit scores and reports can vary.
Mortgage lenders do not expect credit bureaus to provide identical data. As part of the pre-approval experience, lenders often combine reports from two or three bureaus into dual-merge or tri-merge reports, respectively. This allows them to get a broader view of the buyer's credit usage and financial habits.
Merged credit reports show how a home buyer manages credit, pays bills, and handles spending, helping lenders make decisions regarding mortgage applications.
