What Income Counts to Qualify for a Mortgage (and How Co-Borrowers Help)

Quick answer

Most steady income can help you qualify — not just a W-2 paycheck. Social Security, pensions, retirement-account withdrawals, disability, and part-time work with about a two-year history can all count. Because Social Security and many pensions aren't taxed, lenders can “gross up” that income (often 15% on FHA loans, up to 25% on conventional) so it counts at a higher amount. You can also add a co-borrower — including one who won't live in the home — to combine income and strengthen the file.

You don't have to qualify on your own

Plenty of buyers think a loan lives or dies on a single income. It doesn't have to. A co-borrower can be added so the lender counts both incomes together, and that extra income is often the difference between a flat “no” and a comfortable “yes.” There are two kinds:

• Occupant co-borrower: someone who will live in the home with you and shares the loan — usually a spouse or partner.
• Non-occupant co-borrower: a family member who won't live there but helps you qualify (allowed on FHA and most conventional loans).
• Either way, everyone on the loan shares full responsibility for the payments, and each person's credit and monthly debts are part of the review.

A non-occupant co-borrower takes title to the home at closing, so it's a real commitment for them. It's worth a clear family conversation up front before anyone signs.

Retirement and fixed income count

If you're retired or living on a fixed income, you can still get a mortgage. Lenders regularly count the money you actually live on. What they're checking is simple: is it steady, and is it likely to keep coming? These all qualify when documented:

• Social Security retirement, survivor, or disability (SSDI) benefits
• SSI (Supplemental Security Income)
• Company or government pensions and annuities
• Regular distributions from a 401(k), IRA, or other retirement account
• VA disability and other long-term disability income

Income with no end date is usually straightforward. If a source is scheduled to stop — say, a benefit that ends in two years — the lender generally needs it to continue at least three years from your closing date to use it.

Why non-taxable income is worth more than it looks

Here's something a lot of retirees never hear. Social Security and many pensions aren't taxed, but mortgage qualifying is based on gross (pre-tax) income. To keep the comparison fair against taxable pay, lenders “gross up” non-taxable income — they add a percentage back on:

• FHA loans: typically grossed up about 15% (or your actual prior-year tax rate).
• Conventional loans: often up to 25%, or your actual tax rate.

Example: $2,000 a month in non-taxable Social Security can count as roughly $2,300 on an FHA loan after a 15% gross-up. That can meaningfully raise the price range you qualify for. Exact figures depend on your loan program and documentation.

Part-time, seasonal, and side income

Side income can help — but timing matters. Lenders want proof that part-time or seasonal work is stable, so they generally look for about a two-year history of earning it. A job you started last month usually can't be counted yet, even if the pay is good.

• Part-time or second jobs: usually need about two years of consistent history.
• Seasonal work: counted when there's a steady pattern over time.
• Bonus and overtime: often usable with a two-year average.

Just starting a side gig? It's often worth waiting until you have the history — or leaning on your main income and a co-borrower in the meantime.

Other income that can count

Beyond a paycheck and retirement, several other income types can help you qualify when they're documented and likely to continue:

• Self-employment income (tax returns, or bank-statement programs built for the self-employed)
• Rental income from a property you own
• Child support or alimony, when it's court-ordered and will continue
• Investment or dividend income with a track record

If most of your income is self-employed, ask about bank-statement loans — they qualify you on deposits instead of tax-return write-offs.

What to have ready before you apply

The cleaner your paperwork, the faster the answer. Gather these and we can give you a clear picture quickly:

• Award or benefit letters for Social Security, pension, or disability
• Recent 1099s and bank statements showing the deposits land
• Two years of tax returns if you're self-employed
• Photo ID (or ITIN paperwork) and recent pay stubs if you work

Common questions

Can I qualify for a mortgage on Social Security alone?

Yes. Social Security retirement, survivor, and disability income all count, and because it's usually non-taxable, lenders can gross it up so it qualifies at a higher amount. Plenty of retirees buy or refinance on fixed income.

What does “grossing up” income mean?

It's an adjustment lenders make to non-taxable income so it compares fairly with taxable pay. On FHA loans the bump is typically about 15%; on conventional loans it can be up to 25%, or your actual tax rate.

Can a family member help me qualify without living in the home?

Yes — that's a non-occupant co-borrower, allowed on FHA and most conventional loans. Their income helps you qualify, but their credit and debts are part of the review, and they take title and share responsibility for the loan.

Does part-time or a brand-new job count?

Part-time and side income usually need about a two-year history to count. A job you just started often can't be used yet, though your main income and a co-borrower can still carry the file.

Do retirement account withdrawals count as income?

Regular distributions from a 401(k) or IRA can count when they're set up to continue. Lenders look for a steady pattern and enough remaining assets for the income to reasonably keep going.

Can two people combine their income on one loan?

Yes. Adding a co-borrower combines both incomes, which can raise how much you qualify for. Just remember both people's credit scores and monthly debts factor into the decision.
