Buying a home involves several key steps in the mortgage process, especially for first-time buyers. Start by evaluating your finances, including your credit score and debt-to-income ratio. Obtain pre-approval from a lender, then search for homes within your budget. After making an offer and having it accepted, complete a loan application. The lender will underwrite your application and order an appraisal. If approved, you'll receive a commitment letter, followed by closing the deal and moving into your new home.
