Step-by-Step Guide to the Mortgage Pre-Approval Process

By Thao DP Nguyen3 min read

Pre-approval is a detailed review of your income, assets and credit. Follow these steps, document lists and debt-to-income basics to move through it smoothly.

Before you tour homes seriously, it helps to know exactly what a lender is willing to offer you. A pre-approval is that answer in writing, based on a real review of your finances rather than a quick estimate.

Here is the process, step by step, so nothing surprises you along the way.

Pre-Qualification vs. Pre-Approval

These terms are often mixed up. A pre-qualification is usually a rough estimate based on information you provide. A pre-approval involves submitting documents, authorizing a credit check and having a loan professional review your file. The second carries more weight with sellers and gives you a more reliable budget.

Step 1: Gather Your Documents

Lenders generally ask for the following, though exact requirements vary by loan type and your situation:

  • Government-issued photo ID
  • Recent pay stubs and the last two years of W-2s
  • Last two years of tax returns, especially if you are self-employed
  • Recent bank and investment statements, often the last two months
  • Documentation for other income, such as bonuses or rental income
  • Explanations for large deposits or gaps in employment
  • Information about current debts and housing payments

Self-employed buyers should expect to provide more documentation, such as profit and loss statements, since income is evaluated over time.

Step 2: Understand Debt-to-Income Ratio

Debt-to-income (DTI) compares your monthly debt payments to your gross monthly income. Lenders look at it to judge whether a new payment is manageable.

DTI = Total monthly debt payments ÷ Gross monthly income

For example, imagine gross income of $12,000 per month. If your proposed housing payment is $3,800 and you have $1,000 in car, student loan and card minimums, total debts are $4,800. DTI is $4,800 ÷ $12,000 = 40%. Maximum DTI limits depend on the loan program, your credit and other factors, so ask your lender what applies to you.

Step 3: Credit Review

The lender pulls your credit and reviews payment history, balances and recent activity. Check your own reports first and correct errors if you find them. Avoid opening new accounts or making large purchases on credit while this process is underway.

Step 4: Underwriting and Your Letter

Underwriters verify that your income, assets and credit support the loan amount. They may ask for additional documents, which is normal. Respond quickly and completely to keep things moving.

  1. Submit your application and documents
  2. Authorize the credit check
  3. Respond to any follow-up requests
  4. Receive your pre-approval letter with the estimated loan amount and loan type
  5. Ask about how long the letter is valid and when it can be updated

Remember What Pre-Approval Is and Is Not

A pre-approval is not a final loan commitment. The loan still depends on an acceptable appraisal, clear title, property eligibility and no material changes in your finances before closing. Changing jobs, taking on new debt or moving large sums of money can cause problems, so tell your lender before making any major changes.

Use the Number Wisely

Your approved amount is a ceiling, not a target. Compare it to your own comfort level, including taxes, insurance, HOA dues, maintenance and savings goals. Many buyers choose a payment below their maximum approval.
