How Underwriters Analyze a Schedule K-1 for Qualifying Income

When you apply for a jumbo loan in California using income from a partnership, lenders scrutinize your Schedule K-1 far more intensely than a standard W-2. They aren't just looking at the final number; they are evaluating the stability, consistency, and source of that income. Your K-1 is a direct window into the financial health of your business partnership, and for a high-value loan in a market like Los Angeles, lenders need absolute confidence in your ability to repay.

An underwriter’s analysis typically involves a two-year review of both your personal and business tax returns. They look for trends. Is revenue growing? Are profits consistent? A one-year spike in income followed by a weak year is a major red flag. They want to see a predictable pattern that assures them the income used for qualification is likely to continue for at least the next three years. (The data, information, or policy mentioned here may vary over time.)

Key areas of focus include:

Distributions vs. Ordinary Business Income: What Lenders Use

A common point of confusion for partners is whether a lender will use their ordinary business income (Box 1 of the K-1) or their distributions (Box 19). The answer is nuanced, but lenders often start with the lesser of the two figures after adjustments. (The data, information, or policy mentioned here may vary over time.) Their goal is to ensure you are not taking more money out of the business than it is actually earning and can sustainably afford.

Underwriter analyzing business financial documents for a loan

Here’s a practical example. Let's say you are a partner in a successful marketing firm in San Diego looking for a jumbo loan.

The lender’s core principle is sustainability. They will only give you credit for income that the business can demonstrably support year after year without harming its financial position.

What Sections of the Partnership Tax Return Matter Most to a Lender?

Your Schedule K-1 is only one piece of the puzzle. To approve a jumbo loan, lenders require the full partnership tax return, Form 1065, for the last two years. They are digging deep into the business's fundamentals. Three sections are particularly critical.

Key sections of a partnership tax return highlighted

H3: The Balance Sheet (Schedule L)

This schedule provides a snapshot of the company's assets, liabilities, and equity. Underwriters are looking for:

H3: Reconciliation of Income (Schedule M-1)

Schedule M-1 reconciles the company's net income per its accounting books with the income reported on its tax return. This is important because it highlights expenses that are not tax-deductible, such as certain meals and entertainment. It gives the lender a clearer picture of the company's true profitability and cash flow, separate from its tax strategy.

H3: Analysis of Net Income (Schedule M-2)

This schedule tracks the partners' capital accounts from the beginning to the end of the year. It shows capital contributions, net income, distributions, and other items. For an underwriter, Schedule M-2 confirms whether the distributions you took were paid from profits or if they were a return of your initial capital investment. For a jumbo loan, income must come from profits.

Can I Add Back Paper Losses Like Depreciation?

Yes, and this is where a knowledgeable mortgage professional can make a significant difference. Certain non-cash expenses, often called 'paper losses', can be added back to the partnership's net income to increase your total qualifying income. This is because these expenses reduce taxable income but don't actually involve a cash outlay.

The most common add-back is depreciation. Let's imagine your Los Angeles real estate partnership owns several properties.

If you are a 50% partner, your share of this add-back would be $75,000. This amount is added to your base qualifying income, potentially helping you qualify for a larger loan amount. Other potential add-backs include amortization, depletion, and sometimes one-time, non-recurring business expenses, though the latter requires extensive documentation. (The data, information, or policy mentioned here may vary over time.)

What if the Partnership Shows a Loss but I Still Took Distributions?

This scenario is almost always a deal-breaker for a jumbo loan. If the partnership's Form 1065 shows a net loss for the year, but your K-1 shows that you received distributions, it means you were paid from other sources—not profits.

This could be:

Regardless of the source, underwriters view this as fundamentally unsustainable. Taking money from a losing business jeopardizes its long-term health. In this situation, the lender will calculate your qualifying income from the partnership as zero, or even as a negative figure (a loss), which would then be counted against any other income you have.

How Do Guaranteed Payments Affect My Total Qualifying Income?

Guaranteed Payments, reported in Box 4 of your K-1, are a significant advantage in jumbo loan qualification. These are payments made to a partner for services or the use of capital, and they are paid out regardless of the business's profitability for the year. Essentially, they function like a salary.

Because of their reliability, lenders view Guaranteed Payments very favorably. They are considered stable and predictable income. The amount listed in Box 4 is typically added directly to your calculated qualifying income from the partnership's profits.

For example, a partner in a San Diego law firm might receive $200,000 in Guaranteed Payments plus a share of the remaining profits. The lender will add that $200,000 directly to the income calculated from their share of the business's net earnings (after adjustments and add-backs), resulting in a much stronger financial profile.

What Specific Letters Will a Jumbo Lender Require from My CPA?

For nearly any self-employed borrower using K-1 income, and especially for jumbo loans, lenders will require a formal letter from a third-party Certified Public Accountant (CPA). The letter cannot come from an internal bookkeeper or someone who is not a licensed CPA.

This letter serves as an independent verification of the business's health and your income stream. While the specific requirements can vary slightly between lenders, the letter must generally confirm the following:

This letter provides the underwriter with a vital layer of confidence that the financial data presented in the tax returns is accurate and sustainable.
