Can You Use Bonus or Commission Income to Qualify for a Mortgage?
A strong bonus year can feel like it should open up more borrowing power, but lenders tend to be more cautious about variable pay than a borrower’s bank balance might suggest.
The short answer
Yes, bonus and commission income can generally be used to qualify for a mortgage, but lenders typically require a documented history, often two years, showing the income is consistent or trending upward, and they usually average it rather than counting the most recent or highest figure.
Why lenders want a track record first
Base salary is treated as relatively predictable, but bonus and commission pay can swing significantly from year to year depending on performance, company results, or market conditions outside a borrower’s control. Because a mortgage payment is a long-term, fixed obligation, lenders generally want evidence that variable income has a real pattern behind it before counting on it to support that payment. A single unusually strong quarter or year typically isn’t enough on its own.
How the calculation usually works
- Two-year history. Lenders commonly look at two years of this income, similar to how self-employed income is averaged over two years, and generally want to see it reported consistently on tax documents or pay records.
- Averaging, not peak-year counting. Rather than using the best year, lenders typically average the two years together, and may use an even more conservative figure if the trend is declining.
- Declining income scrutiny. If commission or bonus pay dropped meaningfully from one year to the next, a lender may ask for an explanation or apply extra caution, since a downward trend raises questions about what’s likely going forward.
- Employer confirmation. As part of broader income verification, a lender may contact the employer to confirm whether this type of pay is expected to continue.
What happens with a newer job or role
Someone who recently moved into a commission-based role, without two years of history in that specific position, may find that income harder to count right away. Lenders are generally looking for a demonstrated pattern in a similar type of compensation, not just tenure at a company, so a recent transition into commission-based work can mean that income isn’t fully counted until more history accumulates.
How this fits into the overall pre-approval
This income treatment is just one piece of the larger review that happens during pre-approval, alongside credit and assets. Because variable income can be a meaningful part of someone’s total pay, getting an early, honest read on how much of it a lender will actually count can prevent a mismatch between what a borrower expects to qualify for and what the numbers ultimately support.
What to weigh
Because rules and lender practices around variable income can differ and change over time, it’s worth treating any specific averaging approach as a general pattern rather than a fixed formula. Borrowers who rely significantly on bonus or commission pay may find it useful to gather documentation of that income history well before applying, since assembling two years of consistent records after the fact can take longer than expected.
