What Mortgage Underwriters Look for in a CPA Letter

When applying for a mortgage, lenders carefully review every financial detail to ensure borrowers have the ability to repay the loan. This review process is known as mortgage underwriting, and it plays a critical role in determining whether a loan application will be approved.

For self-employed borrowers, freelancers, and business owners, verifying income can be more complex than it is for traditional employees. Instead of relying on simple pay stubs and W-2 forms, underwriters must evaluate tax returns, business income, and financial statements. In many cases, lenders request a CPA letter to provide professional confirmation of key financial information.

Understanding what mortgage underwriters look for in a CPA letter can help borrowers prepare the right documentation and avoid unnecessary delays during the approval process.

Understanding the Role of Mortgage Underwriters

Mortgage underwriters are responsible for evaluating the risk associated with a loan application. Their primary goal is to determine whether the borrower meets the lender’s guidelines and has the financial stability to repay the mortgage.

During underwriting, several factors are carefully reviewed, including:

• Income stability
• Employment or self-employment status
• Credit history
• Debt-to-income ratio
• Financial documentation

For self-employed individuals, verifying income and business activity requires additional scrutiny. This is why lenders may request a CPA letter for mortgage applications as part of the documentation.

What Is a CPA Letter?

A CPA letter is a document prepared by a Certified Public Accountant that verifies certain factual details about a borrower’s financial situation. It provides confirmation from a licensed professional who is familiar with the borrower’s financial records.

The letter is typically used to support other financial documents, such as tax returns and business statements, during the mortgage underwriting process.

Key Elements Mortgage Underwriters Expect in a CPA Letter

For a CPA letter to be useful in the underwriting process, it must contain specific information that helps verify the borrower’s financial situation. Mortgage underwriters typically look for several important elements.

1. CPA Firm Letterhead and Contact Information

The letter should be written on official CPA firm letterhead. This helps confirm the authenticity of the document and ensures that the accountant can be contacted if the lender needs further verification.

The letterhead usually includes:

• CPA firm name
• Address
• Phone number
• Email or contact details

This information allows lenders to verify that the letter was issued by a licensed accounting professional.

2. Confirmation of Self-Employment

One of the most important details underwriters look for is confirmation that the borrower is self-employed.

The CPA letter should clearly state that the borrower operates a business or works as an independent professional. This helps lenders verify the borrower’s employment status when traditional employment documentation is not available.

3. Length of Time in Business

Mortgage lenders typically prefer borrowers who have at least two years of self-employment history. This requirement helps demonstrate that the business has been operating long enough to generate consistent income.

A CPA letter often confirms how long the borrower has been self-employed or how long the CPA has been working with the borrower’s financial records.

This information helps underwriters assess the stability of the borrower’s income.

4. Type of Business Entity

Underwriters may also look for confirmation of the borrower’s business structure. The CPA letter may identify whether the business operates as:

• A sole proprietorship
• A limited liability company (LLC)
• A partnership
• A corporation

Knowing the type of business entity helps lenders better understand how the borrower’s income is reported and structured.

5. Confirmation of Tax Return Preparation or Review

Many CPA letters include a statement confirming that the accountant has prepared or reviewed the borrower’s tax returns.

This helps lenders verify that the borrower’s financial documents have been handled by a qualified professional and that the information provided in the loan application aligns with official tax filings.

6. Confirmation That the Business Is Currently Active

Another key element underwriters often look for is confirmation that the borrower’s business is currently operating.

This helps lenders determine whether the income source is still active and likely to continue. While CPAs generally cannot guarantee future income, they can confirm that the business is active based on their knowledge of the borrower’s financial records.

7. CPA Signature and License Information

To ensure the authenticity of the document, the CPA letter should include:

• The CPA’s signature
• CPA license number or credentials
• Date of issuance

These details confirm that the letter was prepared by a licensed professional who is authorized to provide financial verification.

What CPA Letters Typically Do Not Include

While CPA letters provide helpful verification, they are limited by professional guidelines. CPAs generally cannot:

• Guarantee a borrower’s income
• Predict future financial performance
• Confirm the borrower’s ability to repay a loan

The purpose of the letter is simply to confirm factual information based on the CPA’s professional knowledge of the client’s financial records.

Understanding these limitations helps borrowers avoid requesting statements that accountants are not permitted to provide.

Common Mistakes That Can Cause Issues in Underwriting

Even when a CPA letter is provided, certain mistakes can slow down the mortgage approval process. Some common issues include:

• Missing CPA contact information
• Lack of official letterhead
• Vague statements about employment status
• Incorrect borrower information
• Letters that attempt to guarantee income

Ensuring the letter includes the proper details can help prevent these problems and make the underwriting review smoother.

Final Thoughts

Mortgage underwriting is a detailed process designed to ensure borrowers have the financial stability needed to repay their loans. For self-employed individuals, verifying income and business activity often requires additional documentation beyond traditional employment records.

A CPA letter helps provide professional confirmation of key financial details, including self-employment status, business history, and tax return preparation. When prepared correctly, it can help underwriters verify important information more efficiently and keep the mortgage approval process moving forward.

For self-employed borrowers preparing to apply for a mortgage, understanding what underwriters expect in a CPA letter can help ensure that all required documentation is ready when it is needed.
