After credit, income is the second pillar of qualifying for a Conventional Mortgage. Whether you’re a W-2 employee, self-employed business owner, or earn bonus or commission income, Fannie Mae and Freddie Mac have established guidelines to determine whether your income is stable, predictable, and likely to continue.
Who Are Fannie Mae and Freddie Mac?
Most Conventional Mortgages are ultimately sold to Fannie Mae or Freddie Mac, government-sponsored enterprises (GSEs) created by Congress to provide liquidity and stability to the U.S. housing market.
Although they don’t lend money directly to consumers, they establish the underwriting guidelines most lenders follow for Conventional financing.
Unlike many Non-QM loan programs, Conventional loans are full documentation mortgages. That means lenders must fully document and verify your income before approving the loan. Basically, to obtain the more attractive interest rate products from the government, you must prove documentable & taxable income to qualify.
Typical Income Documentation for W-2 Employees
For most salaried or hourly employees, lenders typically request:
- Most recent 30 days of pay stubs
- W-2s for the previous two years
- Two months of bank statements (when needed to document deposits)
- Employment verification or last two year-end paystubs with yearly totals for base, commission, OT, and bonus
- Federal tax returns if 25%+ of your total income is derived from commission, OT, or bonus
Underwriters review not only your current income but also your employment history and likelihood that the income will continue.
Typical Documentation for Self-Employed Borrowers
Self-employed borrowers generally provide:
- Personal federal tax returns for prior two years
- Business tax returns, when applicable
- Year-to-date Profit & Loss statement, if required
- Business balance sheet, when required
One significant enhancement to Conventional Underwriting allows some borrowers who have been self-employed for more than five years to qualify using only one year of tax returns, provided the automated underwriting system (AUS) approves the file and all investor guidelines are met. This can simplify the loan process for long-established business owners and also bring a larger income vs the normal calculation of a 24 months average.
Bonus, Overtime, and Commission Income
Additional earnings such as bonus, overtime, and commission can often be used for qualifying.
Generally, lenders look for a two-year history of receiving this income and evaluate whether it is stable or increasing.
If bonus, overtime, or commission represents 25% or more of your total qualifying income, federal tax returns are typically required in addition to standard W-2 documentation. Underwriters review tax returns to confirm consistency and identify unreimbursed employee business expenses or other factors that may affect qualifying income.
Declining Income
Income stability is just as important as the amount earned.
If income has declined from previous years, underwriting must determine whether the reduction is temporary or represents a long-term trend. If declining year-over-year by more than 25% — this can impact the approval of the loan.
Stable or increasing income is generally viewed more favorably than declining earnings, even when the borrower currently qualifies.
Retirement Income
It is pretty straightforward. If retirement income is untaxable, we can usually gross-up the income by 125%.
In cases where a new draw is being established from an IRA, 401k, or annuity — we can use the new income with the following documentation: 1) Letter from custodian on their letterhead, explaining the new distribution amount monthly, when it starts, and signed by custodian. 2) The first draw needs to be paid out. 3) Asset statement to prove there is at least 36+ months remaining on the asset total vs 36 months of the new distribution. This is a positive for retirees because a lot of investors require 3-6 months of seasoning for newly established retirement distributions.
Income Tax Requirements
All required federal income tax returns must be filed and any payment plans or tax obligations must comply with investor guidelines. Typically all tax payments need to be current and paid-in-full.
In addition, tax returns provided to the lender are verified directly with the Internal Revenue Service using IRS Form 4506-C (which replaced Form 4506-T for income verification). This helps confirm the tax returns submitted match the records on file with the IRS.
Changing Jobs
Changing employers doesn’t automatically prevent mortgage approval.
If you’re moving to a new employer within the same line of work, qualification is often straightforward, especially if your income remains stable or increases.
If you’re changing careers entirely, the underwriter evaluates your education, training, experience, and whether the new position demonstrates reasonable income stability. Each situation is reviewed individually.
Employment Gaps
Employment gaps of more than six months typically mean you have to be back on the new job for 6+ months. Less than 6 months job-gap can typically just be one month paystubs for the new job.
After returning to work, lenders generally want to see sufficient time back on the job to establish stable employment, although requirements vary depending on the reason for the gap and the overall loan profile.
Supporting documentation may be requested to explain extended absences due to education, military service, medical leave, or family circumstances.
Returning to Work After Disability
Borrowers who previously received disability income and have returned to work may still qualify for Conventional Financing.
Underwriters generally evaluate the current employment income rather than prior disability benefits. They also review the stability of the new employment and verify that the borrower has successfully returned to the workforce. Each situation is unique, particularly if disability income continues in addition to employment income. But typically, we can use this income, it is just how much we can use?
Try to Avoid These Items
Try not to change jobs once you have applied. Notify the lender of any position changes. Try to not change from self-employed to W-2 or W-2 to self-employed. Before taking any employer or 401k loans, talk to us.
Final Thoughts
Conventional underwriting focuses on one simple question: Is your income stable, well-documented, and likely to continue?
Whether you’re a salaried employee, self-employed business owner, commissioned salesperson, or recently changed careers, proper documentation is the key to a successful mortgage approval.
Working with an experienced mortgage professional early in the process allows potential income concerns to be identified before you begin shopping for a home, making your mortgage experience in the Temecula Valley much smoother.
