Commission-Based Income: How Realtors, Salespeople & Brokers Qualify
Commission income is treated differently than salary by mortgage lenders. Here's the 24-month average rule, the Schedule C trap, and how to maximize qualification.
Real estate agents, insurance brokers, car salespeople, stockbrokers, account executives — anyone who earns income primarily through commission — faces a unique mortgage qualification challenge. Commission income is treated more like self-employment than like W-2 salary, even when you receive a W-2. Lenders require longer history, use averages instead of current income, and scrutinize year-over-year trends. The same person earning $150,000/year on commission can be approved for substantially less than someone earning $150,000/year on salary.
This guide explains exactly how commission income gets calculated for mortgage qualification, the Schedule C deduction trap that costs commission earners borrowing power, the difference between 100% commission and base-plus-commission treatment, and the strategies to maximize approval.
The 24-Month Average Rule
Most lenders require 24 months of commission income history and use the 24-month average as your qualifying income — not your current run rate, not your best year, not your most recent month. The 24-month average is calculated by summing your last two years of commission income (from W-2s, 1099s, or tax returns) and dividing by 24 to get your monthly qualifying income.
Example: You earned $80,000 in commissions in year 1 and $120,000 in year 2 (a $100,000 average). Your qualifying monthly income is $100,000 ÷ 12 = $8,333/month. Even though you're currently on pace for $150,000 this year, the lender uses the historical average. This is conservative and frustrating for commission earners in growing careers.
The declining-income exception
If your most recent 12 months of commission income are lower than your prior 12 months, the lender uses the lower number — not the average. Year 1 at $100,000 + Year 2 at $80,000 = the lender uses $80,000 ($6,667/month), not $90,000. A declining trend is treated as evidence of future continuation of the lower amount.
The reverse isn't true: if your most recent year is higher than the prior year, the lender still uses the 24-month average, not the higher number. The asymmetry hurts growing careers and protects against optimistic projections.
The Schedule C Deduction Trap
If you receive commission income as a 1099 contractor and file Schedule C, your qualifying income is your net income (revenue minus business expenses), not your gross commission earnings. Every dollar you deduct on Schedule C reduces your qualifying income dollar-for-dollar.
A real estate agent who grossed $150,000 in commissions but deducted $40,000 in business expenses (car, marketing, dues, MLS fees, supplies) has net income of $110,000. Their qualifying income for the mortgage is $110,000 — not $150,000. The 24-month average applies to net income, not gross.
The trap: aggressive tax minimization (taking every legal deduction) reduces your tax bill but also reduces your mortgage borrowing power. The savings on taxes don't compensate for the loss in mortgage borrowing power. Use our [DTI calculator](/tools/dti-calculator) to model how different income levels affect your borrowing capacity.
Strategic Schedule C planning
In the 24 months before a planned mortgage application, take fewer aggressive deductions on Schedule C. Pay slightly higher taxes (maybe $5,000-$10,000 more total over two years), and you may qualify for $50,000-$150,000 more in mortgage. Talk to a CPA who understands mortgage qualification before making this trade-off. It's not right for everyone, but for many growing commission earners, it's worth it.
Base Salary Plus Commission Treatment
If you receive a base salary plus commission (like many sales jobs), the two components are treated differently. The base salary counts at the gross amount with standard treatment — typically no special requirements beyond the standard W-2 employment documentation. The commission portion is treated like 100% commission income with the 24-month average rule.
Example: $50,000 base salary + $75,000 in commissions = $125,000 total income. Base salary qualifying income: $50,000 ÷ 12 = $4,167/month. Commission qualifying income (24-month average): varies based on history. Combined qualifying monthly income is the sum.
If your base salary is high relative to commission, your qualifying income tracks more closely with your total comp. If your commission portion dominates (which is common in financial services, real estate, and senior sales roles), your qualifying income lags significantly behind your actual earnings.
100% Commission vs Base + Commission: Approval Differences
Pure 100% commission earners are treated more skeptically than base + commission. The base provides a floor — even in a bad year, the base salary continues. With 100% commission, there's no floor. Lenders may require additional documentation, longer history (24 months minimum, sometimes 36), and stronger compensating factors.
Many lenders prefer base + commission income, even if the commission portion is most of the total. A real estate agent who works as an associate broker with a $25,000 base (even if it's a small portion of their $200,000 total) is treated more favorably than the same earner with no base. If you're considering switching to a new brokerage and have the choice between a higher commission split with no base and a lower split with a base, the lower split with a base helps your mortgage application.
Bonus Income Treatment
Bonuses (separate from commissions) are treated similarly to commissions — 24-month average, declining-trend caveat applies. Annual bonuses, quarterly bonuses, and target-based bonuses all fall in this category. The lender wants 24 months of consistent receipt to count them as qualifying income.
One-time bonuses (signing bonuses, retention bonuses, project completion bonuses) typically don't count for qualifying. They're seen as non-recurring and unreliable. Even if you've received multiple 'one-time' bonuses in your career, they don't establish a pattern that lenders trust.
Documentation Commission Earners Need
Beyond standard mortgage documents, commission earners should prepare:
For W-2 commission earners
2 years of W-2s showing total compensation and breakdown. Pay stubs from the last 30 days. Employer verification of employment letter showing position, tenure, base salary (if any), and commission structure. If your commission income is paid through a separate vehicle (LLC, S-Corp), include those tax returns and K-1s.
For 1099 commission earners
2 years of tax returns with all schedules (Schedule C is critical). 1099s from all paying entities. Year-to-date earnings statements from your principal employer (the broker dealer, brokerage firm, etc.). Brokerage agreements or independent contractor agreements documenting your commission structure.
For all commission earners
Year-over-year tracking: a simple spreadsheet showing your monthly commissions for the past 24 months. This helps you and the lender understand trends. Calendars or production reports showing your active deals and pipeline.
How Commission Earners Get Denied
Common denial reasons for commission earners:
Insufficient history
Less than 24 months in your current commission role. Solution: wait until you have 24 months, or find a lender with more flexible requirements (some non-QM lenders work with 12 months of history plus strong compensating factors).
Declining income trend
Most recent 12 months below prior 12 months. The lender uses the lower number. Solution: improve your earnings before applying, or wait until the trend reverses.
Excessive Schedule C deductions
Net income too low relative to your borrowing needs. Solution: reduce deductions in the 24 months before applying, or use a bank statement loan that bases qualification on deposits rather than tax returns.
Variable monthly income too volatile
Months of $0 and months of $50,000 average to the same as months of $10,000 each, but underwriters get nervous about volatility. Solution: prepare a strong narrative about your business model and consistency, or use a bank statement loan.
Bank Statement Loans for Commission Earners
Bank statement loans qualify you based on 12-24 months of bank deposits rather than tax returns. For commission earners with high gross commissions but aggressive Schedule C deductions, this is often a better path than conventional. The lender averages monthly deposits, applies an expense factor (typically 50% for service businesses), and uses the result as qualifying income.
Example: $200,000/year in commission deposits = $16,667/month average × 50% expense factor = $8,333/month qualifying income. If your tax return shows net income of $5,000/month after deductions, the bank statement approach gives you $3,333/month more in qualifying income — translating to roughly $100,000-$150,000 more in borrowing power.
Trade-offs: rates are typically 0.5-1.5% above conventional, down payment requirements are 10-20% (vs 3-5% for conventional), and not all lenders offer them. Worth it when conventional doesn't qualify you for the home you want.
Frequently Asked Questions
I just became a real estate agent — how long before I can use my commission income?
24 months minimum for most lenders. Some non-QM lenders work with 12 months plus strong compensating factors (large down payment, high credit, low DTI from other income). If you have a spouse with W-2 income, you can sometimes use only their income to qualify for a smaller home now, then refinance to access more borrowing power once your commission income has 24 months of history.
Does it matter if my commissions come from one firm or many?
Mostly no, as long as the total income is consistent. Real estate agents working with one broker over 24 months and stockbrokers working with one firm look the same to underwriters as freelancers with many clients — what matters is the total income and stability. If you've recently switched firms but stayed in the same field, lenders typically count the prior firm's income as continuous.
What about deferred commissions paid later?
Deferred commissions (like trailing commissions on insurance products) typically count as qualifying income with 24 months of history, similar to regular commissions. The income source is what matters, not the timing of payment.
If I have a great pipeline but a bad past year, can I get approved?
Conventional: no. Lenders look at history, not pipeline. Non-QM bank statement loans: sometimes yes, if your recent bank deposits reflect the pipeline conversion. The challenge: pipeline doesn't show in tax returns or bank statements until it converts to actual income. Plan to wait until your pipeline becomes commissions in your bank account.
Should I incorporate as an S-Corp before applying for a mortgage?
Probably not in the 24 months before applying. Incorporating restarts the self-employment clock for many lenders — they want 24 months of net income from your current entity. If you've been a Schedule C sole proprietor for 5 years and incorporate to an S-Corp 18 months before applying, many lenders treat that as 18 months of new self-employment history rather than continuous. Wait until after closing to restructure your business.
