To understand how pre-approval affects your credit, we need to discuss credit inquiries. When you apply for credit, such as a loan or credit card, the lender typically pulls your credit report to assess your creditworthiness. These inquiries are categorized as either "hard" or "soft."
When you are purchasing a home, your lender may recommend you obtain a mortgage pre-approval before you find the home of your dreams. There are some benefits to being pre-approved before you find a home, but oftentimes, people confuse pre-qualifications with pre-approvals.
