Credit gets most of the attention when veterans think about qualifying for a home. But a strong credit score does not get a loan approved on its own. Lenders also want to know whether the payment fits your income.
For VA loans, that question is answered two ways: your debt-to-income ratio and your residual income. Understanding both, before you apply, puts you in a much better position.
What debt-to-income means
Your debt-to-income ratio, or DTI, compares your monthly obligations to your stable monthly income.
Under the VA's underwriting rules, the ratio takes your anticipated monthly housing expense — the new mortgage payment, including taxes and insurance — plus your other monthly obligations, and divides that by your stable monthly income.
A simple example: if your new housing payment would be $1,600, you have a $400 car payment and $150 in card minimums, and your stable monthly income is $5,500, your DTI is $2,150 ÷ $5,500, or about 39%.
The 41% guideline
VA regulations set a benchmark DTI of 41% or less.
That is a guideline, not a hard ceiling. A loan with a higher ratio can still be approved, but it generally gets more scrutiny. Under the regulation, a DTI above 41% calls for a second-level review and a written justification from the underwriter — unless the veteran's residual income exceeds the VA's guideline by at least 20%.
Lenders can also set stricter limits of their own. That is one more reason to talk to more than one lender.
Residual income: the part that makes VA loans different
Residual income is what makes VA underwriting different from most other loan types. Instead of looking only at a ratio, it asks a practical question: after the mortgage and your other obligations are paid, is there enough left each month to live on?
The VA publishes residual income guidelines based on family size, the region of the country, and the loan amount. The figures come from Bureau of Labor Statistics data on what households actually spend.
This is why a veteran with a larger family may need more income to qualify for the same house, and why two veterans with the same DTI can get different results. Ask your lender to show you the residual income calculation for your file.
Which debts count
For VA loans, the regulation describes significant liabilities as accounts that are generally long-term — 10 months or more — and requires all known debts, including alimony and child support, to be documented. In practice, lenders typically look at:
- Car loans
- Student loans
- Credit card minimum payments
- Personal loans
- Child support and alimony
- Other mortgages
Shorter-term debts are still considered when the lender looks at whether you can meet family expenses, and lenders apply detailed rules for things like student loans in deferment. Ask how each of your debts will be counted.
How VA disability income fits
Lenders use income that is stable and likely to continue. VA regulations also allow special consideration for verified nontaxable income once it is established that the income is likely to continue. Since VA disability compensation is generally not taxable, ask your lender specifically how they will count it — and bring your benefit letter.
And if you receive VA disability compensation, you are generally exempt from the VA funding fee — a meaningful amount that is sometimes missed. Make sure your lender knows about your rating.
What lenders may weigh in your favor
When a file is borderline, VA regulations allow underwriters to consider compensating factors. Examples include excellent long-term credit, conservative use of consumer credit, minimal consumer debt, long-term employment, and significant liquid assets.
None of these replaces income. But they can make the difference on a close call.
How to improve your numbers before applying
Pay down revolving balances. Lower card balances can mean lower minimum payments, which lowers DTI. It often helps your credit score at the same time.
Avoid new debt before and during the process. A new car loan a month before applying can change the whole picture.
Document all your income. Benefit letters, pay stubs, tax returns. Income you cannot document may not count.
Pick a price range that leaves breathing room. The maximum you qualify for is not the same as what fits your life. Residual income is a floor, not a budget.
Shop more than one lender. Rates, fees, and overlays vary. The guarantee is the same everywhere; what you pay is not.
Verify before you rely on it
VA loan rules are detailed and lenders apply them with some discretion. This is a general overview, not a lending decision or financial advice. The VA's home loan pages and your lender are the authority on your situation.
