It's an exciting time! You're ready to begin the home-buying process by going house hunting and purchasing your dream home.

Before you start packing boxes, however, you need to get your financial affairs in order. The first step in preparing to buy a home is getting mortgage pre-approval.

To decide if you qualify for a home loan, lenders assess your credit history to determine your ability to make monthly payments and maintain a favorable financial situation. To make the assessments needed, lenders require documentation to verify income, assets, and expenses.

A Checklist of Documents to Get Started

As you begin the quest for a mortgage preapproval letter, you'll have to turn over a bunch of documents containing financial information. Below is a checklist of the five most common documents you'll need.

1. Personal Identification

To obtain a preapproval letter, you must provide a valid form of ID to prove your identity. State-issued driver's licenses, passports, and U.S. alien registration cards are all acceptable. You'll also need to provide your contact information.

2. Social Security Card

Your Social Security number allows lenders to check your credit history and run a comprehensive background check. Your credit score and history play a major role in determining loan eligibility.

3. Proof of Income

Lenders want to verify you have steady income to make mortgage payments. Common documents include:

4. Proof of Assets

Lenders will want to see that you have enough money saved for a down payment and closing costs. Gather these documents:

5. Employment Verification

Be prepared for lenders to verify your employment directly. They may contact your employer to confirm your position, salary, and length of employment.

Additional Tips for a Smooth Pre-Approval Process

What Happens After Pre-Approval?

Once pre-approved, you'll receive a letter stating how much you can borrow. This letter is typically valid for 60–90 days. Use this time to:

  1. Start house hunting within your approved budget
  2. Work with a real estate agent to find properties
  3. Make competitive offers backed by your pre-approval letter
  4. Continue maintaining your financial profile—avoid changing jobs or making large purchases

Why Pre-Approval Matters

In competitive markets, sellers often prioritize offers from pre-approved buyers. It shows you're serious, financially prepared, and ready to close. Getting pre-approved gives you a significant advantage over buyers who haven't taken this important step.
