Variable income like overtime, bonuses, and commissions can help you qualify for a premium home on Mercer Island, but only if you document it correctly.

When you are trying to buy a home, especially in a premium market like King County, your base salary is often only part of the story. If you rely on commissions, quarterly bonuses, or consistent overtime to boost your purchasing power, you need to know how lenders actually look at those numbers. Underwriters do not just look at your current pay rate and multiply it by forty hours. They want to see stability and a clear track record before they use variable income to approve your file.
To count this extra income, the standard rule of thumb is a clear two year history of receiving it with the same employer or within the same line of work. If you have been getting bonuses for six months, we generally cannot use that money to qualify you for a loan. We need to establish that the money is reliable, recurring, and likely to continue for at least three more years. This falls under the general guidelines found in our resource hub on mortgage qualifying rules, which explains how lenders calculate your total buying power.
Establishing the Two Year Track Record
Underwriters are not trying to make your life difficult when they ask for tax returns, W2s, and your final year end paystubs. They are looking for a pattern of stability. If your commission income fluctuates, they want to understand why. For instance, if you made eighty thousand dollars in commissions last year but only forty thousand the year before, they will average those two years together. That gives them a monthly qualifying figure of five thousand dollars, not the sixty six hundred dollars you might have hoped for based on your most recent success.
What happens if the trend goes the other way? If you made one hundred thousand dollars in bonuses two years ago and that dropped to fifty thousand dollars last year, averaging them is rarely an option. Underwriters view declining variable income as a sign of instability. In many cases, they will only qualify you based on the lower, more recent year, or they might reject that portion of your income entirely unless your employer can provide a compelling explanation showing the income has stabilized.
The documents required to prove this are very specific. We will need your last two years of W2 statements, your two most recent federal tax returns, and your most current year to date paystubs showing a breakdown of base pay versus overtime, bonus, or commission. If your paystubs lump everything together, we will have to request a written verification of employment from your HR department to break out each income type.
Local Realities on Mercer Island
This income calculation matters immensely when you are shopping in high value areas like Mercer Island real estate. Property values here mean that even a small change in your qualified monthly income can prevent you from securing financing on a home. Because many professionals here work in tech, finance, or corporate management, their total compensation packages are heavily weighted toward annual stock awards, performance bonuses, and commissions. Understanding how to package this variable income is the difference between getting the keys to a home on the water or losing out on the deal.
The local market has shifted away from the wild bidding wars of the past, turning into a more balanced environment. Today, sellers are open to real inspections and actual negotiations, meaning we have the breathing room to structure your loan correctly. High property taxes and local HOA fees in certain parts of King County residential neighborhoods mean your debt to income ratio is already carrying a heavy load. You cannot afford to have an underwriter discount your bonus income at the last minute because of a missing year end paystub.
Let's look at a quick checklist of what you need to gather if you want to use variable income for your purchase:
- Your last two years of W2 forms showing consistent earnings.
- Year end paystubs from the previous two years to show the breakdown of bonus or overtime.
- Your most recent consecutive paystubs covering a full thirty days of current employment.
- Complete federal tax returns with all schedules, particularly Schedule C if you receive 1099 commissions.
- The contact information for your HR department so we can quickly secure a written verification of employment.
VA Loans and Variable Income
For veterans and active duty service members looking to buy, VA home loans offer some of the most flexible qualifying guidelines available. The VA program does not set a strict maximum debt to income ratio, focusing instead on your residual income, which is the money you have left over each month after paying your mortgage, utilities, and other debts. However, the requirement for stable income still applies. If you are using overtime or part time military income to qualify, the underwriter must still see a two year history of receipt.
When structure drives the deal, you can use the flexibility of a VA loan to negotiate seller concessions or a temporary interest rate buydown. Because you do not need a down payment for a VA loan in most cases, you can direct your cash toward buying down the rate. To see how these numbers shake out, you can estimate your total monthly housing cost by typing your anticipated purchase price, tax rate, and estimated insurance costs into our tool, then adjust the interest rate field to see the impact of discount points or temporary buydowns.
Underwriters on VA loans are looking for reassurance that your income is reliable. If you have recently changed jobs but stayed in the same line of work with a similar pay structure, we can often make a strong case to count your bonus or commission. Keep in mind that while VA loan limits no longer apply to borrowers with full entitlement, these rules and county level calculations can change, so you should always verify the current guidelines with me when you are ready to apply.
Questions I get about this
Can I use my bonus income if I have been at my new job for less than two years?
Generally, you need a full two year history with the same employer to count bonus income. However, if you transitioned to a similar role within the same industry and had a consistent bonus structure at your previous company, some underwriters will accept a one year history at the new job. You will need to provide the final paystubs and W2s from your previous employer to prove the continuity of that income.
What if my commission income went down this year compared to last year?
If your commission income has decreased, the underwriter will look at it with extra caution. In most cases, they will not average the two years. Instead, they will use only the lower, more recent year's income to calculate your qualifying debt to income ratio. If the drop is substantial, they may disallow the commission income entirely unless there is a clear, documented reason for the temporary dip, such as a major health event or a territory reorganization that has since been resolved.
Dom's take
I was surprised by how many buyers in late 2026 still assumed they had to skip inspections and pay cash over list price just to get a seller's attention. This balanced, normalizing market is exactly the kind of environment I enjoy coaching people through because the panic has left the room. We finally have the time to sit down, analyze your variable pay, structure the loan properly, and build a monthly payment on purpose instead of just accepting whatever terms are thrown at us during a weekend bidding war.
Negotiating points, securing seller paid buydowns, and matching the right loan program to your actual compensation structure are the tools that matter now. When you are buying a home, the list price is just a starting point, and the real victory is found in how we structure your financing. If you have bonus or commission income that needs careful calculation, we can map out a solid strategy before you ever write an offer, ensuring you face the market with absolute confidence.
How I'd handle it
If I were using my own money to buy a home right now, I would never write an offer without having my loan officer fully run my variable income through an automated underwriting system first. I do not guess on commissions or bonuses, and neither should you. I analyze the paystubs, average the numbers exactly the way an underwriter will, and verify the continuity of the income upfront so there are zero surprises once we are under contract.
