Understand how underwriters analyze Schedule K-1 and business tax returns to verify self-employed income, and how this impacts your qualifying options in the Spokane area.

Getting a mortgage when you run an S corporation or a partnership is different from having a regular job. If you get a W-2 from your business, you might think that is all we need to look at. In reality, any time you own 25 percent or more of a business, guidelines require us to look past your personal earnings and review the financial health of the entire company.
This is a major part of the qualifying process for self-employed business owners. When you understand what an underwriter is looking for on your tax returns, you can prepare the paperwork ahead of time and avoid last-minute delays during your home purchase.
Why Underwriters Look Past Your W-2
If you own a business, you likely use a Schedule K-1 to report your share of income, losses, and distributions. An underwriter uses this form to determine if your business has the financial strength to pay you. They are not accusing you of anything when they ask for business tax returns, they are simply verifying that your business earnings are stable and likely to continue for at least three years.
To calculate your qualifying income, the underwriter looks at the company's net ordinary income, your percentage of ownership, and any cash distributions you actually received. If you want to see how these calculations affect your home purchasing power, you can use the affordability calculator to adjust your estimated monthly income and see what price range fits your budget.
Business structures like S corporations allow for a lot of tax planning. However, what is good for your tax bill can sometimes reduce the income available for a mortgage. We look at the business balance sheet to make sure the company has enough liquid assets to support the income you are claiming, even if you do not draw it all out as a salary.
Spokane Business Owners and Local Real Estate
If you are buying a home or managing real estate in the Spokane area, local market dynamics play a big role. In Spokane, we see a wide range of business owners, from agricultural partnerships in the outlying areas to professional services in downtown Spokane. The type of business you run can influence how an underwriter views your income trends, especially if your business has seasonal income fluctuations typical of Eastern Washington.
With mortgage rates hovering near 7 percent in late 2026, as reported by financial publications like The Washington Post [17] and Fortune [18], structuring your loan correctly is more important than ever. Buyers in Spokane are finding that choosing the right financing program, negotiating seller concessions, or using business assets for a down payment can have a much bigger impact on their monthly payment than trying to grind down the seller on the list price.
What You Must Provide for Underwriting
To keep your loan moving forward, you need to gather the correct documents early. Underwriters cannot accept partial packages, so having these files ready will prevent back-and-forth emails that drag out your closing timeline.
Here is the exact list of documents you need to collect if you have S corporation or partnership income:
- Two years of personal federal tax returns, including all schedules.
- Two years of business tax returns, which means Form 1120S for S corporations or Form 1065 for partnerships.
- Schedule K-1 for each business entity, showing your percentage of ownership.
- A year-to-date profit and loss statement signed by you.
- Three months of business bank statements to verify the profit and loss statement is accurate.
Self-Employed Income and Reverse Mortgages
If you are an older business owner looking to tap into your home equity, you might be considering different options. Many senior homeowners do not realize that you can qualify for reverse mortgages even if you are self-employed. While these loans do not have traditional monthly mortgage payments, underwriters must still perform a financial assessment to ensure you have enough residual income to pay your property taxes, homeowners insurance, and basic maintenance.
When verifying income for a reverse mortgage, the underwriter reviews your business tax returns and K-1 forms using the same basic principles as a standard purchase loan. They want to see that your business is stable and that you have a consistent flow of cash to cover your ongoing housing obligations. Proving this stability upfront keeps your reverse mortgage moving smoothly through the approval pipeline.
Questions I get about this
Can I use business funds for my down payment?
Yes, you can use business funds for your down payment and closing costs. However, the underwriter will require a letter from your CPA or accountant stating that withdrawing those funds will not negatively impact the daily operations of your business, and we will verify that the business account has sufficient liquidity remaining after the transfer.
What happens if my business tax returns show a net loss?
A business loss on your tax returns will generally reduce your qualifying income. The underwriter must deduct the business loss from your personal income, which can lower your borrowing capacity. If the loss was a one-time event due to a specific, non-recurring expense, we can sometimes write a letter of explanation and provide documentation to ask the underwriter to exclude it from the calculation.
Dom's take
"We spent years building this business, and now it feels like the bank is treating us like a risk." A client told me this last week when they saw the underwriter's list of business conditions. This is the market I like coaching people through. Nobody is panicking, we have time to structure the loan properly, and the monthly payment is something we build on purpose instead of accept. Instead of rushing to close a deal with waived contingencies, we can actually look at the tax returns, find the add-backs like depreciation, and build a file that makes sense to the underwriter.
Managing self-employed income files takes some extra effort, but it is incredibly rewarding when we get the structure right. If you run a business in Spokane, do not let a long checklist of document requests scare you away from buying or refinancing. It is just a puzzle we need to solve together to show the lender that your business is as strong as you know it is.
How I'd handle it
If this were my own money, I would have my CPA print out my complete tax returns and business financials the moment they are filed so they are ready to go. I would never try to hide a business loss or a complex partnership structure from my loan officer. Being upfront about how your business makes and spends money is the fastest way to get an accurate pre-approval and avoid surprises during the underwriting process.
