Lenders verify income to show that it is stable, that it has a history, and that it is reasonably likely to continue. A thick folder of documents is evidence for that test. It is not an approval.
The checklist below follows Fannie Mae's Selling Guide for conventional loans it will buy. FHA, VA, USDA, and non-agency lenders use their own lists. Read this next to the first-time homebuyer guide and the debt-to-income guide, which show where verified income goes once the lender has it.
What is the lender trying to prove?
Fannie Mae calls stable and predictable income a foundation of underwriting. The lender has to document three things: the income is stable, there is a history of actually receiving it, and it is reasonable to expect it to continue.
If the income has no defined end date and the required history is in the file, the lender can treat it as likely to continue unless something in the file says otherwise. If the income expires, or it depends on drawing down an asset, the lender must document that it will continue for at least three years from the application date.
If the lender learns you are moving to a lower pay structure, for example a pending retirement or a new job at lower pay, the lower amount is what counts. Last year's higher W-2 does not override a known pay cut. Non-U.S. citizens meet the same employment and income verification standards as U.S. citizens.
What do wage earners usually hand over?
For employment income, Fannie Mae's documentation rules are the same whether Desktop Underwriter or a person underwrites the file. Pay stubs, W-2s, and tax returns have to meet the same tests either way.
The most recent pay stub must be dated no earlier than 30 days before the initial application date. It must include all year-to-date earnings and enough detail to calculate the income. If a stub is too thin for that math, the lender gets more paper. W-2s cover the most recent one-year or two-year period, based on the income type, and must name you as the employee. A year-end pay stub for the full year, or an adequate IRS wage transcript, can stand in for a W-2.
When the Desktop Underwriter validation service confirms employment from an asset report, the findings say which paper items you can skip. That changes the format. It does not drop the income test.
Base pay is the straightforward piece. Bonus, overtime, commission, and tips are variable, and one good month is not a history. If you need that pay to qualify, the lender asks for the history that income type requires. Last month's overtime is not in the qualifying number until the underwriter puts it there.
How is self-employed and gig income documented?
Fannie Mae treats you as self-employed if you own 25 percent or more of a business. Gig work reported on a Schedule C usually lands here. A smaller ownership share is a different income type, with its own rules.
The review looks for cash you can rely on for the mortgage, not the gross sales of the business. Income that a partnership or S corporation reports on your Form 1040 may not have been distributed to you. The lender looks at whether the business has distributed income, or could, without undermining the business.
Before approval, the lender analyzes the stability of your income, the location and nature of the business, demand for what it sells, the financial strength of the business, and whether it can keep generating and distributing enough for the payment.
The usual history is two years of prior earnings. A shorter history can still be considered if the latest signed personal and business returns show a full 12 months from the current business, and the file documents prior income at the same or a greater level in the same kind of work, or in work with similar responsibilities. The lender then weighs your experience and how much debt the business has taken on.
Verification is signed federal returns filed with the IRS for the past two years, personal and sometimes business, with schedules. Complete IRS transcripts for those years can replace the copies. One year of returns is allowed only in a narrower case: the business has existed for five years, you have owned 25 percent or more for five consecutive years, and the returns support the application. Each business is judged on its own.
The lender completes a cash-flow analysis, Fannie Mae's Form 1084 or an equivalent, and keeps it in the file. Bank deposits alone do not replace that analysis on a standard conventional file.
What else changes the number that counts?
Alimony, child support, retirement pay, Social Security, and rental income each have their own documents in the same chapter. A deposit in your checking account is not, by itself, qualifying income.
Nontaxable income gets a specific adjustment. The lender first verifies that it is nontaxable and likely to continue, using award letters, policy agreements, account statements, tax returns, or similar records. If it is, the lender may add an amount equal to 25 percent of that nontaxable income when building the qualifying figure. That gross-up is a calculation rule. It is not a reason to inflate a budget on your own.
Non-occupant co-borrower income can be used if it meets the same standards as the occupant borrower's income. It does not erase the down payment, debt-to-income, or loan-to-value limits that apply when a non-occupant is on the loan. On a manual file it cannot cover serious recent credit problems of the person who will live in the house.
Once the income figure is set, it becomes the bottom of the debt-to-income ratio. Walk through that math on the debt-to-income guide, then see how a lender looks at the whole application in the preapproval guide. Borrowers whose income does not fit these molds sometimes look at non-QM loans, which use different documents. Nothing here says a file will be approved.
Gather the pay stubs, W-2s, or returns your income type calls for, then read the first-time homebuyer guide for where that paperwork sits in the rest of the purchase.
Once that income figure is set, one way to turn it into a housing budget is The 28/36 Rule: How Much House Can You Afford?.
