What Income Counts for a Mortgage: the Sources Lenders Can Use, and the Ones They Cannot

A lender counts income you can document, that has been stable, and that is likely to continue. Income that fails any one of those three tests generally cannot be used to qualify – no matter how real the money is or how reliably it lands in your account.

That framework is the whole answer. Everything else in this guide is an application of it to a specific pay type.

The short version

• Three tests, all three required: documented, stable, likely to continue (Fannie Mae Selling Guide B3-3.1-01; HUD Handbook 4000.1).
• Base wages, self-employment profit, retirement and disability income, military allowances, and most variable pay can count when the paper supports them.
• Undocumented cash, a raise that has not taken effect, and one-time windfalls generally cannot be used as qualifying income – though a windfall may still count as an asset.
• Non-taxable income such as BAH and BAS may be grossed up, which raises the qualifying figure on paper without changing your take-home pay.
• Income with a defined expiration date generally must be documented as expected to continue for at least three years from the note date (Fannie Mae Selling Guide B3-3.1-01; general – confirm current).

The three tests every income source has to pass

Underwriting is not a search for reasons to decline. It is a repeatable question asked of every dollar: can this be verified, has it behaved consistently, and will it still be there after closing?

Test one: it is documented

Documentation means a third party confirms the money – not you. Pay stubs, W-2s, filed returns and IRS transcripts, award letters, signed court orders, and a written verification of employment are the artifacts underwriters actually accept.

Fannie Mae’s Selling Guide B3-3.1-01 requires that income be stable, have a documented history of receipt, and be reasonably expected to continue. FHA calls its qualifying-income concept Effective Income in HUD Handbook 4000.1 – income that may be used to qualify a Borrower for a Mortgage. The vocabulary differs; the underwriting question does not.

Our take: most income problems we see are documentation problems in disguise. The money is real. The paper trail is thin.

Test two: it has been stable

Stability is about pattern, not size. One enormous month proves nothing. The same figure arriving month after month proves a great deal.

How much history a lender wants depends on the source. Salaried base pay can often be established from a current pay stub and a verification of employment, while variable pay usually gets averaged over a longer look-back – commonly 12 to 24 months (general – confirm current).

Underwriters also weigh stability beyond the paycheck – tenure, industry, and whether the history behind the number looks like a trend or an accident.

Test three: it is likely to continue

Continuance is the test borrowers underestimate. When income has no defined expiration date and the history of receipt is documented, a lender can generally conclude it will continue without hunting for extra proof.

When income does have a defined expiration date – an alimony or child support order, a fixed-term note, certain trust or annuity distributions – the burden flips. Fannie Mae’s continuity-of-income standard directs the lender to document that the income is expected to continue for at least three years from the note date (Fannie Mae Selling Guide B3-3.1-01; general – confirm current).

Why the frame beats the list

Lists of acceptable income types go stale. The three tests do not. Hold them in your head and you can predict the answer for a pay type nobody has written an article about, including whatever your employer invents next quarter.

Our take: if you can name the document that proves it, the months that show the pattern, and the reason it continues, you already know how underwriting will treat it.

Income sources lenders can usually count

The sources below routinely make it into a qualifying figure. What varies between them is the documentation and the averaging method, not whether the category is allowed at all.

Wage income from a W-2 job

Base wages are the cleanest case: a current pay stub, prior W-2s, and a verification of employment. The arithmetic of turning that paperwork into a monthly figure is its own subject, and we cover it separately in our guide to how lenders calculate W-2 income.

Hourly borrowers get one extra wrinkle. The lender has to decide what a normal week looks like, which is why a fluctuating schedule is averaged rather than annualized from the most recent check.

Overtime, bonus, commission, and shift differential

Variable pay counts, but it is averaged rather than taken at face value, and our breakdown of overtime and shift differential income explains how that averaging works. A 12- to 24-month look-back is the common pattern (general – confirm current).

The practical trap is timing. A borrower whose overtime dropped this year may be averaged on the lower recent figure even though the two-year total looks strong, and a borrower whose overtime just started may not have enough history yet to use any of it.

Self-employment and business income

For self-employed borrowers the qualifying number comes from filed returns and business documentation, not from deposits or gross revenue. Write-offs that reduce taxable income also reduce qualifying income – a trade-off worth planning well before an application, and one to discuss with a tax professional.

If you own a business, hold K-1 interests, or file a Schedule C, start with our guide to qualifying for a mortgage when self-employed.

Retirement, Social Security, and disability income

Pension payments, IRA and 401(k) distributions, Social Security, and disability benefits are all countable when documented with award letters, benefit statements, or distribution records showing the amount and the expected continuance.

Much of this income is non-taxable, which matters for the gross-up discussion further down.

Child support, alimony, and other defined-term income

These count when there is a court order or written agreement, evidence of consistent receipt, and documentation that payments continue for the required period. This is the classic three-year-continuance category (Fannie Mae Selling Guide B3-3.1-01; general – confirm current).

Rental income

Rental income counts, usually from Schedule E on filed returns or, on a new purchase, from a lease plus the appraiser’s market rent opinion. Lenders generally apply a vacancy factor rather than crediting gross rent (general – confirm current).

Income you have but cannot use

This is the section that surprises people. The money below is real, spendable, and frequently ineligible as qualifying income.

Cash you were paid but never documented

Cash income that never appeared on a tax return, a pay stub, or an employer record generally cannot be counted. There is no third party to verify it and no record against which to test whether it continues.

Deposits that do not match documented income also invite questions, which is why bank statements in underwriting get read line by line.

Our take: this is the most painful conversation in our office, and the fix is never quick – it usually starts with the next tax filing.

A raise that has not taken effect yet

A promised or scheduled raise is generally not usable until it is in effect and documented. What sometimes helps is a signed employer letter confirming the new rate with an effective date on or before closing, plus a pay stub reflecting it. Ask your lender what evidence they will accept, because this varies by lender.

One-off windfalls

A legal settlement, an inheritance, a lottery win, or the gain on a one-time asset sale is not monthly income – nothing about it repeats. It can still be powerful in a file as documented, sourced assets for down payment or reserves, which is a different lever than qualifying income.

A job that starts after closing

The offer-letter path is real but narrow. Fannie Mae’s Selling Guide addresses income from a job that has not yet begun in B3-3.3-03, Employment Offers or Contracts. The offer has to be fully executed and non-contingent, the start date has to fall inside a defined window around the note date – no earlier than 30 days before it and no later than 90 days after it – and the lender either obtains a paystub before delivery or documents reserves, such as six months of PITIA for the subject property or enough to cover the qualifying monthly liabilities until the job starts (general – confirm current).

Every one of those conditions is a document rather than a conversation. If a move is coming, read what we wrote about buying a home while changing jobs before you give notice.

Military income in Colorado Springs: BAH, BAS, and the ETS date

Fort Carson, Peterson Space Force Base, Schriever Space Force Base, and the United States Air Force Academy all sit in this market, so military pay is a routine part of local mortgage files. It is well supported by the agency guides, and it has two features that regularly complicate an income review.

Allowances count, and non-taxable pay may be grossed up

Basic Allowance for Housing and Basic Allowance for Subsistence are generally countable income when documented on a Leave and Earnings Statement, as are many special and incentive pays. The governing requirements sit in the VA Lender’s Handbook (VA Pamphlet 26-7), and individual lenders apply them differently – general, confirm current.

Because BAH and BAS are generally not taxed, they can often be adjusted upward before the ratio calculation – a step the industry calls a gross-up of non-taxable income. The mechanics of grossing up income for a mortgage differ by agency and by lender, and the adjustment factors are set by guideline rather than negotiated (general – confirm current). Whether any specific allowance or benefit is taxable in your situation is a question for a tax professional.

Our walkthrough of how VA loans count military income covers the pay types line by line. Service-connected disability compensation is likewise countable when documented, and current VA disability pay charts show what an award letter should reflect.

An ETS date inside 12 months changes the file

If a service member’s separation date falls within roughly 12 months of the loan (general – confirm current), the continuance test is live and a Leave and Earnings Statement alone will usually not settle it. Lenders commonly ask for a statement of intent to reenlist or extend with supporting documentation from the command, or for documented post-service income instead. The exact requirement varies by lender – ask yours early.

Our take: raise this on day one rather than letting an underwriter discover the ETS date in week two. It is a solvable condition. It is only a crisis when it is a surprise.

Transitioning service members

A borrower separating from service is not a weaker applicant – the file simply has to answer the continuance question a different way. Retirement pay, a signed civilian offer, VA disability compensation, or a co-borrower’s documented income can each carry that test. Which combination a given lender accepts depends on its written policy, so ask before the file is submitted.

Why two people with identical pay stubs qualify differently

Because qualifying income is only half the equation. The other half is what you owe, which is why your debt-to-income ratio does the real work of deciding a loan amount.

Borrowers are also often surprised by what DTI in a mortgage actually includes – and by which pay types their particular lender averages over 12 months rather than 24.

This is why two people with the same income get different mortgage payments, even at the same lender in the same week.

What a lender is not allowed to do with your income

Federal law limits how a creditor may treat income based on where it comes from. A creditor may not discount or exclude from consideration an applicant’s income because it is derived from part-time employment or is an annuity, pension, or other retirement benefit, or because of a prohibited basis – which includes the fact that the income derives from a public assistance program. Regulation B implements the Equal Credit Opportunity Act and is enforced by the CFPB.

What a lender can do is apply consistent standards for verification, consistency, and continuance. The three tests are about how the income behaves, never about the person receiving it.

How to document income so underwriting does not stall

File completeness on day one is the actionable half of every timing question, and income is where incompleteness usually hides.

The two clocks

Two separate clocks run in every file. The first is underwriter turn time – how long the queue takes to reach your file. The second is condition-clearing time – how long you take to return what the underwriter asks for.

Missing income documents do not move the first clock at all. They extend the second one, repeatedly, because each incomplete answer produces another condition.

The day-one income packet

The list below is a general starting point – every lender publishes its own, so confirm current requirements before you start gathering.

1. Most recent 30 days of pay stubs for every job, plus two years of W-2s.
2. Two years of filed tax returns if you are self-employed, own rental property, or receive commission income.
3. Award letters or benefit statements for Social Security, pension, annuity, or disability income.
4. Court orders plus receipt history for any support income you want counted.
5. A current Leave and Earnings Statement for military pay, and a reenlistment or continuation statement if the ETS date is near.
6. A short written explanation of any employment gap, job change, or large non-payroll deposit.

A gap, a job change, or an unusual deposit is usually resolved with a letter of explanation rather than a decline.

Lenders also commonly run a verbal verification of employment shortly before closing, and our note on employment verification in a mortgage explains what triggers a re-check.

When the lender’s policy is the obstacle, not your income

Agency guidelines set the floor. Individual lenders add overlays on top of that floor, and overlays are where identical files get different answers on variable pay, offer letters, and continuance documentation.

That is where a wholesale mortgage broker in Colorado Springs earns the fee – matching the file to a lender whose written policy fits the income, or getting a second read on a file that stalled earlier. That is access to more than one rule book, not a promise of any particular outcome.

Frequently asked questions

What income counts for a mortgage?

Any source you can document, that has been stable, and that is likely to continue. Wages, self-employment profit, variable pay, retirement and disability benefits, military allowances, support payments, and rental income all qualify when the paperwork satisfies all three tests (Fannie Mae Selling Guide B3-3.1-01; HUD Handbook 4000.1).

Can I use cash income if I can prove I received it?

Generally only if it was reported – on a tax return, a pay stub, or an employer record. Bank deposits alone establish neither source nor continuance. Our take: the practical path is reporting the income going forward and qualifying once filed returns exist to support it.

Will a lender count a raise that has not started yet?

Usually not until it is effective and documented. Some lenders will consider a signed employer letter stating the new rate with an effective date on or before closing, sometimes paired with a pay stub reflecting it. This varies by lender – ask yours before building a budget around the higher figure.

Does BAH count as income for a mortgage?

Generally yes. Basic Allowance for Housing and Basic Allowance for Subsistence are countable when documented on a Leave and Earnings Statement, under the VA Lender’s Handbook (VA Pamphlet 26-7) and the lender’s own policy – general, confirm current. Because they are generally not taxed, they may also be grossed up, which raises the qualifying figure without changing your take-home pay.

What happens if my ETS date is within a year of closing?

The continuance test becomes active. Lenders commonly ask for a statement of intent to reenlist or extend plus supporting documentation from the command. Alternatively, documented post-service income such as a non-contingent civilian offer or retirement pay can carry the test. Specific requirements vary by lender – ask yours.

Can I qualify using a job I have not started?

Sometimes. Fannie Mae addresses it in B3-3.3-03, Employment Offers or Contracts, under narrow conditions: a fully executed, non-contingent offer, a start date no earlier than 30 days before the note date and no later than 90 days after it, and either a paystub obtained before delivery or documented reserves (general – confirm current). Every condition is a document, so confirm the exact list early.

Why did one lender count my overtime and another one did not?

Overlays. Agency guidelines set the floor, and individual lenders add stricter documentation or averaging rules on top of it. Our take: that is a submission-choice problem rather than a borrower problem, because the same file can meet one lender’s written policy and miss another’s.
