Alaska Mortgage Guide: Using Commission Income

Real estate agents, car salespeople, insurance brokers, and other commission-based workers make up a meaningful share of Alaska’s workforce. If more than 25% of your income comes from commissions, lenders apply a specific set of underwriting rules.

How Lenders Calculate Commission Income

Because commission income can fluctuate month to month, lenders typically:

1. Average your commission income over the most recent two years, using tax returns and W-2s or 1099s.
2. Compare year-over-year trends — a declining trend can result in a lower qualifying income figure or, in significant cases, disqualification of the income entirely.
3. Subtract unreimbursed business expenses reported on tax returns (like a real estate agent’s marketing costs or a salesperson’s mileage), since these reduce your effective qualifying income even if they reduced your tax bill.

Documentation Checklist

• Two years of personal tax returns, including all schedules
• W-2s or 1099s from your employer(s) or brokerage
• A year-to-date pay stub or commission statement, if available
• A written verification of employment (VOE) confirming your compensation structure and likelihood of continued employment

What If You’re New to Commission-Based Work?

If you recently transitioned to a commission role — say, moving from a salaried position into real estate sales in Anchorage or Wasilla — you may not have the standard two-year history lenders prefer. Some lenders will consider a shorter history (as little as 12 months) if:

• You have a strong, relevant employment history in the same field
• Your base pay plus a partial commission history supports the loan amount
• You have significant reserves or a co-borrower with stable income

Base Salary Plus Commission

Many Alaska sales roles combine a modest base salary with commission on top. Lenders document each component separately: base salary is verified through pay stubs like standard W-2 income, while the commission portion follows the two-year averaging approach described above.

Seasonal Commission Swings

Certain Alaska industries — tourism-adjacent sales, fishing gear and marine sales, and seasonal retail — see sharp commission swings tied to the summer season. Lenders average the full 12 or 24 months rather than annualizing a strong summer, so plan your income expectations accordingly when estimating what you’ll qualify for.

Related Income Documentation

Commission income shares underwriting principles with other variable-pay sources. If part of your compensation also includes vested stock or RSUs, see our RSU and stock income mortgage guide. Self-employed commission earners running their own brokerage or agency should also review our gig and self-employed income guide for parallel documentation tips.

Tips to Strengthen a Commission-Based Application

1. File taxes with your mortgage plans in mind — aggressive expense deductions lower your qualifying income even though they lower your tax bill.
2. Keep detailed records if you switch employers within the same commission-based field, since a lender may still average your combined history across employers under similar compensation structures.
3. Build reserves — commission-based borrowers with several months of mortgage payments in savings present a stronger overall file.

Commission-based sales professionals in Anchorage real estate and auto sales make up a large share of this borrower type — start gathering your two-year documentation early.

Frequently Asked Questions

How do lenders calculate commission income for an Alaska mortgage?

Lenders typically average commission income over the most recent two years using tax returns, and subtract unreimbursed business expenses to arrive at qualifying income.

Can I qualify for a mortgage with less than two years of commission income history?

In some cases yes, particularly if you have a strong, relevant employment background or significant reserves, though most lenders prefer the standard two-year history.

Does a declining commission income trend hurt my mortgage application?

Yes, a significant downward trend can lower the qualifying income a lender uses, or in some cases result in that income not being counted at all.

Do unreimbursed business expenses reduce my qualifying commission income?

Yes, expenses deducted on your tax returns related to earning commission income are typically subtracted from your gross income when lenders calculate what counts for qualification.

Are seasonal commission spikes averaged or counted at their peak value?

Lenders average commission income across the full 12- or 24-month period rather than annualizing a seasonal peak, which can result in a lower qualifying figure than your best month suggests.
