Why Lenders Scrutinize Commission for Texas Jumbo Loans

For high-earning sales professionals in competitive Texas markets like Dallas and Plano, a compensation structure heavily weighted toward commission is common. While it allows for significant earning potential, it presents a unique challenge when applying for a jumbo loan. Unlike a predictable bi-weekly salary, commission income is inherently variable. Lenders, especially in the jumbo space where loans exceed conforming limits and carry more risk, prioritize stability and predictability above all else.

A jumbo loan underwriter’s primary goal is to verify that your income is likely to continue for at least the next three years. A fixed salary provides that confidence easily. Commission, however, can fluctuate with market conditions, sales cycles, and personal performance. An underwriter sees a low base salary and high, variable commissions as a potential risk that must be thoroughly mitigated through extensive documentation and analysis. They need to build a case that your historical earnings create a reliable pattern, ensuring you can comfortably handle a large mortgage payment long-term. This is why the qualification process for commission-based borrowers is far more in-depth than for salaried W-2 employees.

Establishing a Track Record: Commission History Requirements in Dallas

To build a convincing case for income stability, lenders require a documented history of your earnings. For jumbo loans in the Dallas-Fort Worth metroplex, the industry standard is a minimum of two years of commission income history. This two-year look-back period allows underwriters to identify a trend, smooth out seasonal peaks and valleys, and establish a dependable average.

Ideally, this history should be with the same employer or, at the very least, within the same industry and role. For example, if you were a top medical device salesperson in Plano for 18 months and recently moved to a competitor in Dallas in the same role with a similar commission structure, a lender may consider that a continuous history. However, switching from selling software to selling luxury real estate would reset the clock, and you would likely need to build a new two-year track record in your new field before qualifying for a jumbo loan.

This two-year rule is rarely flexible in the jumbo mortgage world. (The data, information, or policy mentioned here may vary over time.) A shorter history, even with exceptionally high earnings, is often a non-starter because it doesn’t provide enough data for the lender to confidently project future income stability.

Income Calculation: The 12-Month vs. 24-Month Average

The most common method lenders use to calculate qualifying income from commissions is a 24-month average. This approach provides the most conservative and stable income figure, which is paramount for high-value jumbo loans.

Here’s how it works:

  1. The lender gathers your commission earnings from the past 24 months.
  2. They sum the total amount.
  3. They divide that total by 24 to arrive at your qualifying monthly income.

Example:

Calculating commission income for a jumbo loan

Some borrowers ask if a 12-month average is possible, especially if their most recent year was significantly better. While some conventional loan programs might allow this, it is highly uncommon for jumbo loans. (The data, information, or policy mentioned here may vary over time.) A lender might only consider a 12-month average if you have a very long history (5+ years) of consistently increasing commission income and a strong overall financial profile. For most applicants in Dallas, planning for a 24-month average is the safest and most realistic approach.

What If My Commission Income Recently Declined?

A year-over-year decline in commission income is one of the most significant red flags for a mortgage underwriter. It immediately undermines the core requirement of income stability. If your earnings have decreased, lenders will adjust their calculation to be even more conservative.

Typically, the lender will calculate your income two ways and use the lower of the two figures:

  1. The 24-month average.
  2. The most recent 12-month average (or year-to-date income extrapolated over 12 months).

Example of Declining Income:

In this scenario, the underwriter will use $15,833 as your qualifying monthly income, not the higher 24-month average. If the decline is substantial (e.g., more than 20%), you may need to provide a detailed Letter of Explanation (LOE). A good LOE provides a compelling and verifiable reason for the dip, such as a one-time market disruption, a change in commission structure that has since stabilized, or a temporary leave. Without a strong explanation, a significant decline could jeopardize your loan approval.

Essential Documentation to Prove Income Stability

Organization is key to a smooth underwriting process. You must provide a complete and clear picture of your earnings. Be prepared to submit the following documents:

Gathering these documents proactively will demonstrate that you are a serious and well-prepared borrower, helping to streamline your jumbo loan application in a fast-moving market like Plano.

The Role of an Employer Letter in Your Plano Jumbo Loan Application

Beyond the standard VOE, a well-crafted letter from your employer can be a powerful tool to support your application. This is not a standard requirement, but it can provide valuable context that numbers alone cannot. This is particularly helpful if your income stream is complex or has shown some variability.

An effective employer letter should:

For an underwriter reviewing a large loan for a property in Plano, this letter adds a layer of human-backed confidence. It helps them conclude that your high performance is not a fluke but a sustainable pattern.

How Unreimbursed Business Expenses Impact Your Qualification

This is a critical and often-overlooked factor for commission-based salespeople. Even though the Tax Cuts and Jobs Act of 2017 eliminated the federal tax deduction for most W-2 employee business expenses, mortgage lenders are required to analyze your provided tax returns and subtract any unreimbursed expenses (historically found on Form 2106) directly from your gross qualifying income.

Example of Expense Impact:

This $1,250 monthly reduction can significantly alter your debt-to-income (DTI) ratio, potentially lowering the loan amount you qualify for. It is crucial to be aware of how these past deductions will be treated and to discuss this with your mortgage advisor early in the process.

Are There Special Jumbo Loan Programs for Commission Earners?

Yes, but you often have to look beyond the big national banks to find them. While most lenders follow strict underwriting guidelines, some offer more flexible portfolio loans. A portfolio loan is a mortgage that the lending institution keeps on its own books instead of selling it on the secondary market. This gives them greater discretion over the approval criteria.

A portfolio lender in the Fort Worth or Dallas area might:

These programs are not advertised widely and are typically accessed through experienced mortgage brokers who have established relationships with a network of niche lenders. For a high-earning professional on commission, partnering with an expert who understands these specialized jumbo loan products can be the difference between approval and denial.
