Understanding the Basics of Mortgage Underwriting

You've applied for a mortgage, found a home, and submitted a stack of financial documents. Then you hear your loan is going to underwriting. If you've never bought a home before, that word alone can make the process sound more intimidating than it needs to be.

Mortgage underwriting is an important part of the home loan process. It's when the lender reviews information about your finances, loan, and the property to determine whether the mortgage meets applicable lending requirements. You can't control every part of underwriting, but you can prepare for it. Understanding what may be reviewed, keeping your documents organized, and avoiding unnecessary financial changes can help you navigate this stage with greater confidence.

What Is Mortgage Underwriting?

Mortgage underwriting is the process of evaluating a home loan application before final approval. During underwriting, information provided during the mortgage application process is reviewed and verified. Depending on the loan and your financial situation, this can include your:

• Income and employment
• Credit history
• Existing debts
• Assets and savings
• Down payment funds
• Financial documentation
• Property information
• Other information relevant to the mortgage

The purpose is to determine whether the loan meets the lender's and applicable loan program's requirements. Think of underwriting as the verification stage of your mortgage journey. It connects many of the pieces you've already provided into a more complete picture.

What Does an Underwriter Look For?

There isn't one single factor that determines the outcome of underwriting. Instead, an underwriter may evaluate several aspects of your application.

Income and employment

Your lender will generally need to verify the qualifying income being used for the mortgage. Depending on your circumstances, supporting documentation may include:

• Pay stubs
• W-2 forms
• Tax returns
• Employment information
• Documentation related to other qualifying income

The documentation needed can vary, particularly if you're self-employed or receive income from multiple sources.

Credit and existing debt

Your credit profile and financial obligations can also play a role in underwriting. An underwriter may review information about outstanding debts and credit accounts when evaluating your overall mortgage application. That can include obligations such as:

• Auto loans
• Student loans
• Credit card debt
• Personal loans
• Other applicable recurring obligations

This information may also factor into your debt-to-income ratio, or DTI, which compares certain monthly debt obligations with your gross monthly income.

Assets and funds

Mortgage underwriting can also involve verifying assets associated with your home purchase. For example, your lender may need to document funds being used toward your down payment, closing costs, or other requirements associated with the transaction. That's one reason you could be asked to provide bank or asset statements.

The property

Underwriting isn't solely about your personal finances. Information about the property being financed may also need to be reviewed. Depending on the mortgage, that can include an appraisal and other property-related documentation.

Why Is the Underwriter Asking for More Documents?

You've already submitted documents, so getting another request can naturally raise an uncomfortable question: Is something wrong?

Not necessarily. Additional documentation requests can be a normal part of the mortgage review process. The lender may need clarification or updated documentation to verify information associated with your application. Your financial circumstances can also determine what documentation is necessary. You might be asked to provide additional information related to:

• Income
• Employment
• Assets
• Debts
• Financial transactions
• Other information appearing within your documentation

If you receive a request you don't understand, ask your mortgage team what information is needed rather than guessing.

Front Door Tip: A request for another document doesn't automatically mean your mortgage is in trouble. Focus on understanding what's needed and supplying complete and accurate information.

How Can You Prepare for Underwriting?

You don't need to become a mortgage expert before underwriting begins. A little organization, however, can make navigating the process easier.

1. Keep Your Financial Documents Organized

Create a dedicated place for your mortgage documentation, whether that's a secure digital location or physical folder. Keep copies of documents you've already submitted so you can easily reference them if questions come up. Depending on your circumstances, useful documents to keep accessible may include:

• Recent pay information
• Tax documents
• Bank and asset statements
• Identification
• Employment information
• Records associated with funds for your home purchase

Only provide sensitive financial information using methods approved by your lender.

2. Respond to Requests Promptly

During underwriting, your mortgage team may contact you with questions or request additional documentation. Pay attention to communications related to your mortgage and try to respond promptly. If you can't immediately provide something that's requested, communicate with your mortgage team rather than letting the request sit unanswered.

3. Be Complete and Accurate

When providing information, accuracy matters more than trying to anticipate what someone wants to see. If you're asked for a particular document or a complete statement, provide what your lender has requested. If something isn't clear, ask. Trying to interpret a request yourself can sometimes create more back-and-forth than simply getting clarification first.

Be Careful About Major Financial Changes

This is one of the most important things for homebuyers to understand during the mortgage process. Your financial circumstances can change between the day you apply and the day you close. If you're considering a significant financial move while your mortgage is being reviewed, speaking with your mortgage team first can help you understand whether the change could affect your application or require additional documentation. Here are several situations to be mindful of.

Opening new credit

Getting a new credit card or financing another purchase can change your credit and debt picture. That doesn't mean your life has to stop while you're buying a home. But if you are considering taking on new credit, talk with your mortgage team before making the decision.

Making a major financed purchase

A new car or another large purchase can come with a new monthly payment. Because lenders evaluate your existing financial obligations, taking on additional debt during the mortgage process could affect information associated with your application. That new furniture set may look great in the house you've found, but financing it before you've closed may not be worth complicating your mortgage application.

Changing jobs

People change jobs for all kinds of reasons. If your employment changes while your mortgage is being reviewed, notify your mortgage team as soon as possible. They can explain what additional information or documentation may be required based on your circumstances.

Moving significant amounts of money

When you're buying a home, you may be moving funds between accounts or receiving money from another permitted source. Those transactions could require documentation. Rather than assuming a financial transaction won't matter, talk with your mortgage team if you're uncertain about how moving or receiving funds could affect your documentation.

Keep Saving While You Wait

Buying a home can come with plenty of expenses. Even if you've already accounted for your down payment and estimated closing costs, preserving some financial flexibility can be valuable as you approach closing and homeownership. You may encounter expenses related to:

• Moving
• Utilities
• Maintenance
• Repairs
• Furnishings
• Other costs associated with settling into your home

A new front door is exciting. Having something left in savings after you walk through it can be pretty exciting, too.

What Happens After Underwriting?

The outcome of underwriting depends on the individual mortgage application. You may receive requests for additional information or conditions that need to be addressed before the loan can proceed. Your mortgage team can explain what is required for your specific application. Once applicable requirements have been satisfied and the loan is able to move forward, you'll get closer to the next major milestone: closing. That's when you'll review important final loan information and prepare to complete your home purchase.

Underwriting Doesn't Have to Be a Mystery

Mortgage underwriting can sound intimidating because much of the review happens behind the scenes. But your role can be relatively straightforward: Stay organized. Provide accurate information. Respond to requests. Communicate when something changes. Ask questions when you're unsure.

And perhaps most importantly, don't panic simply because you're asked for another document. Every mortgage application is different, and additional questions can be part of verifying the information needed to move the loan through the process. Take it one request and one step at a time. Before you know it, underwriting may be another milestone you've passed on your way to your new front door.
