How Traditional Mortgage Loans Calculate Self-Employed Income

One of the biggest questions I get from self-employed borrowers is:

"Will writing off business expenses hurt my chances of qualifying for a mortgage?"

The answer is it depends on the loan program.

We have several different loan programs available, and each one calculates income differently.

For traditional mortgage programs—including Conventional (Fannie Mae and Freddie Mac) and Government loans (FHA, VA, and USDA)—we calculate your income based primarily on your net income.

That means we start with your business revenue and subtract your business expenses to determine the income that can be used to qualify for a mortgage.

The good news is that not every business expense is treated the same.

Depending on the loan program, certain expenses may be added back into your qualifying income, such as:

• Depreciation

• Amortization

• A portion of business mileage

• Certain business debts, such as auto loans or credit cards, when they are properly documented as business expenses and also appear on your personal credit report. In these situations, we don't want to count the same expense twice, so those payments may be excluded from your debt calculations.

A Simple Example

Let's say your business generated $600,000 in gross sales during the year.

If your business expenses total $500,000 (including payroll, marketing, advertising, supplies, and other operating expenses), your tax return may show $100,000 of qualifying income before any allowable add-backs.

Although your business brought in $600,000, a traditional mortgage lender may initially qualify you using approximately $100,000 of income.

That's why your tax strategy can have a significant impact on your mortgage qualification.

Consistency Matters

Lenders are also looking for stable income over time.

If your income drops significantly from one year to the next—generally more than 20%—the underwriter will likely ask for an explanation.

That doesn't necessarily mean your loan can't be approved. Sometimes there's a perfectly reasonable reason for the decrease, such as investing back into the business, taking time off, or experiencing a one-time expense.

The important thing is understanding the story behind the numbers and documenting it properly.

Emma's Tip: Don't change your tax strategy just to qualify for a mortgage. Your CPA's job is to help you minimize taxes, and my job is to help you understand how those decisions may affect your financing options. The best results happen when your CPA and mortgage lender work together before you file your taxes—not after.
