Automated Underwriting
How the VA Automated Underwriting System Works in 2026
The VA Automated Underwriting System (AUS) evaluates VA loan applications using tools like Fannie Mae’s Desktop Underwriter or Freddie Mac’s Loan Product Advisor. It assesses credit, income, and DTI, often approving DTIs up to 55% with compensating factors. Manual underwriting is required if AUS returns a ‘Refer’ status, offering a second chance for approval.

How the AUS Works
- Credit: AUS evaluates FICO score, payment patterns, and derogatory events to assess creditworthiness.
- Income: Reviews gross monthly income and employment history for stability and reliability.
- DTI: Standard VA guideline is 41%, but AUS can approve up to 55% with strong factors.
- Residual Income: Calculates funds left after debts and taxes, unique to VA loans, ensuring financial security.
AUS Findings and What They Mean
- Approve/Eligible: Meets all requirements, allowing streamlined documentation and faster closing, typically 25–35 days.
- Refer/Eligible: Eligible for VA loan, but needs manual review for compensating factors by an underwriter.
- Refer/Ineligible: Resolve eligibility issues like entitlement verification before resubmitting for approval.
- Manual Review: Necessary when AUS flags issues, requiring deeper evaluation and more documentation.
Manual Underwriting: A Second Chance
- Credit Scores: Scores below 620 often trigger manual review, requiring additional documentation.
- Thin Credit: Lack of active tradelines may lead to manual underwriting for risk assessment.
- Recent Events: Recent bankruptcy or foreclosure can necessitate manual review for loan approval.
- Timeline: Manual underwriting takes 45–65 days, longer than the 25–35 days for AUS approval.
Common Misconceptions
- Myth: AUS approval is not solely a pass/fail test for VA loans.
- Reality: AUS evaluates risk layers; strong areas can offset weaker ones.
- Fix: Strengthen compensating factors like reserves, residual income, or a strong employment history for better AUS outcomes.
Frequently Asked Questions
What happens if AUS returns a ‘Refer’ status?
A ‘Refer’ status means manual underwriting is needed. A human underwriter reviews compensating factors, such as residual income and credit history, requiring more documentation and potentially delaying closing.
Can a high DTI still get AUS approval?
Yes, AUS can approve DTIs up to 55% if strong compensating factors like high residual income or cash reserves are present. This flexibility aids approval.
How does AUS impact VA loan closing times?
AUS typically speeds up closing to 25–35 days with streamlined documentation. Manual underwriting extends this to 45–65 days due to additional review.
The Bottom Line Up Front
Every VA loan in 2026 — purchase, refinance, jumbo — runs through automated underwriting. AUS is the decision-maker. It pulls your credit, calculates your DTI, evaluates your income stability, and returns a finding in minutes. An Approve/Eligible means you’re on the fast track. A Refer means the file needs manual review. Either way, AUS sets the terms for what happens next. For more, see our guide on first-time homebuyer mistakes.
Lenders submit your file to Desktop Underwriter (DU) or Loan Product Advisor (LPA). The system applies VA guidelines and investor overlays simultaneously. If the file is clean — solid credit, stable income, reasonable DTI — AUS issues an Approve/Eligible with minimal conditions. If something flags — thin credit, high DTI, recent derogatory events — you get a Refer, which routes the file to manual underwriting for deeper review.
The critical thing to understand: AUS is not a pass/fail test. It is a risk-layering engine. Strength in one area — strong credit, significant reserves, low DTI — can offset weakness in another. A 640 score with 28% DTI and 12 months of reserves will likely get approved. A 720 score with 55% DTI and no reserves might still get a Refer. The system weighs everything together.

What AUS Actually Does on a VA File
AUS is a digital risk engine that evaluates your complete financial profile against VA and investor guidelines. It does not replace an underwriter — it front-loads the decision so the lender knows immediately whether the file has a clear path to closing or needs additional documentation and review.
For VA loans, lenders use one of two platforms. The system you are submitted through depends on your lender’s setup, not on anything you choose.
| AUS Platform | Developed By | What It Does |
|---|---|---|
| Desktop Underwriter (DU) | Fannie Mae | Evaluates credit, income, assets, and liabilities against VA and investor guidelines |
| Loan Product Advisor (LPA) | Freddie Mac | Same evaluation — different algorithm and risk model, same three possible findings |
Both systems pull your tri-merge credit report, calculate your debt-to-income ratio, and assess income stability. They apply the VA’s own guidelines — residual income thresholds, occupancy requirements, entitlement verification — plus whatever investor overlays the lender carries. The entire process takes minutes.
AUS Findings Explained
AUS returns one of three findings. Each one tells the lender exactly what happens next with your file — how much documentation is required, whether a human underwriter needs to review it, and what conditions must be cleared before closing.
Approve/Eligible
- Your file meets all VA and investor guidelines
- Streamlined documentation — fewer tax returns, bank statements, and verifications required
- Fastest path to closing, typically 25–35 days from contract
- Conditions issued are usually standard: VOE, appraisal, title, flood cert
Refer/Eligible
- The file does not meet AUS thresholds but may still be viable
- Routes to manual underwriting for human review
- Full documentation required — 2 years of tax returns, 2 months of bank statements, employment verification
- Compensating factors like stable rent history, strong residual income, or significant reserves can justify approval
Refer/Ineligible
- The file fails baseline eligibility — usually a disqualifying event like an active foreclosure, insufficient entitlement, or occupancy violation
- Cannot proceed until the underlying issue is resolved
- Not the same as a permanent denial — many of these are fixable with time or restructuring
The difference between Approve/Eligible and Refer is substantial. An Approve cuts your documentation burden roughly in half and keeps the closing timeline tight. A Refer means more paperwork, more time, and the outcome depends on whether your compensating factors are strong enough to satisfy the underwriter reviewing the file.
What AUS Evaluates on Your File
AUS does not look at one thing and make a decision. It layers multiple risk factors together and weighs them against each other. A weakness in credit can be offset by strength in income and reserves. A high DTI can be offset by strong residual income and long employment history. The system evaluates the whole picture.
Core Evaluation Factors
- Credit score and payment history — your FICO score, number of tradelines, derogatory events, and time since last negative item
- Debt-to-income ratio — all monthly obligations including the proposed mortgage payment divided by gross monthly income; the VA guideline is 41% but AUS approves higher with compensating factors
- Income stability and documentation — AUS evaluates whether your income is likely to continue; 2 years of consistent employment history strengthens the file
- Asset reserves — not required on every VA loan, but AUS weighs reserves as a positive factor, especially on higher loan amounts or weaker credit profiles
- Residual income — the VA-specific requirement; the amount of money left after all monthly obligations, calculated by family size and geographic region
Your approval is based on three pillars: credit, income, and assets. Strength in one pillar can offset weakness in another, up to a point. A borrower with a 740 FICO and 48% DTI will likely get an Approve because the credit strength compensates for the higher debt load. A borrower with a 600 FICO and 48% DTI will almost certainly get a Refer because neither pillar is strong enough to carry the other.
How Military Income Works in AUS
Military income is one of the strongest qualifying tools on a VA file. AUS accepts base pay, non-taxable allowances, and disability income — and the gross-up on non-taxable sources can significantly increase your qualifying power.
| Income Source | Taxable? | Gross-Up Eligible? | How It Helps |
|---|---|---|---|
| Base Pay | Yes | No | Primary qualifying income — verified through LES or DFAS records |
| Basic Allowance for Housing (BAH) | No | Yes — up to 25% | Can add hundreds per month to qualifying income in high-cost areas |
| Basic Allowance for Subsistence (BAS) | No | Yes — up to 25% | Often overlooked; adds $400–$450/month before gross-up |
| VA Disability Income | No | Yes — up to 25% | Stable, permanent income source that strengthens any VA file |
| Combat/Hazardous Duty Pay | No (in combat zone) | Yes — up to 25% | Must document likelihood of continuance for at least 12 months |
The gross-up works like this: if you receive $2,000/month in BAH, your lender can count $2,500/month as qualifying income (25% gross-up). That extra $500/month can lower your DTI by 1–2 percentage points, which is often enough to flip a Refer to an Approve. Make sure every non-taxable income source is included on your application — omitting BAH or BAS is one of the most common mistakes on VA files.
What Happens When AUS Returns a Refer
A Refer is not a denial. It means AUS could not approve the file based on the data submitted, and the loan needs manual underwriting review. This is a standard path — not an unusual one. Thousands of VA loans close every month after an initial Refer finding.
When your file goes to manual, the underwriter evaluates compensating factors that AUS cannot weigh with the same nuance. Stable rent payment history over 12+ months, strong residual income above VA thresholds, significant asset reserves, and long-term employment history all count.
Common Reasons for a Refer Finding
- Credit score below 620 — most lender AUS models flag files under this threshold as a Refer
- DTI above 50% — even with strong residual income, AUS often defers to manual review at this level
- Limited credit history — fewer than three tradelines or less than 12 months of credit activity
- Recent derogatory events — late payments, collections, or charge-offs within the past 12–24 months
- Gap employment — income interruptions or job changes within the past 2 years
The key with a Refer is working with a lender who does manual underwriting in-house. Not all lenders offer it. Some wholesale lenders and large banks will not manually underwrite VA files at all — they only accept AUS Approve findings. If your file gets a Refer, you need a lender who reviews compensating factors and makes approval decisions internally.
Collections, Charge-Offs, and AUS
Unpaid collections and charged-off accounts do not automatically disqualify you from an AUS approval — but they do impact your credit score, which impacts the finding. The question is how recent, how large, and whether they have been addressed.
Medical collections under $2,000 typically have minimal impact on your FICO score under current scoring models. Consumer collections — unpaid credit cards, personal loans, utility bills — carry more weight, especially if they are recent or unresolved. Negotiating a pay-for-delete agreement with collection agencies before you apply can remove the tradeline entirely and improve both your score and your AUS outcome.
Charged-off credit cards show as a $0 balance on your credit report but remain as derogatory marks for 7 years. Settling charged-off accounts before applying can improve your overall credit profile, though the derogatory mark stays. The score improvement from reducing active negative tradelines is often enough to push a borderline file from Refer to Approve.
Credit Score Minimums Are Lender Overlays
The VA does not set a minimum credit score for VA loans. There is no VA rule that says you need a 620 or a 580 or any specific number. The credit score floors you see advertised are lender overlays — restrictions individual lenders place on top of VA guidelines.
A lender with a 620 overlay will not submit your file to AUS if your score is below 620. That is the lender’s rule, not the VA’s. A lender with a 580 overlay will submit your file but route it to manual underwriting if AUS returns a Refer — which it likely will at that score level.
| Credit Score Range | Typical AUS Finding | Lender Overlay Impact |
|---|---|---|
| 720+ | Approve/Eligible (most files) | No overlay issues — clean path |
| 680–719 | Approve/Eligible (most files) | Minimal overlay friction |
| 640–679 | Approve or Refer depending on DTI and reserves | Some lenders add reserve requirements at this tier |
| 620–639 | Refer likely unless DTI is low and income is strong | Most lenders’ floor — below this they won’t submit |
| 580–619 | Refer expected | Manual underwriting required; not all lenders offer this |
| Below 580 | Refer/Ineligible likely | Very few lenders approve below 580; strong compensating factors required |
If you have been told your credit score is too low for a VA loan, the correct question is whether it is too low for that specific lender — not whether it is too low for the VA program itself. A lender with no overlays follows standard DU guidelines and lets AUS make the call.
How to Improve Your AUS Result Before Applying
If you are not in a rush, spending 30–60 days preparing your file before submitting to AUS can change the outcome. Small moves — paying down balances, correcting errors, documenting income properly — flip Refer findings to Approve more often than borrowers expect.
Highest-Impact Moves
- Pay credit card balances below 30% utilization — this is the single fastest way to improve your FICO score; a 20-point jump from utilization reduction is common within one billing cycle
- Dispute and correct errors on your credit report — incorrect late payments, wrong balances, or duplicate accounts can suppress your score by 40–80 points
- Use rapid rescore through your lender — if you have paid off debt or removed errors, a rapid rescore reflects those changes in 3–5 business days instead of waiting for the next reporting cycle
- Document all income sources with current LES, tax returns, and award letters — incomplete income documentation is a top reason files that should Approve end up with a Refer
- Avoid opening new credit accounts or making large purchases in the 90 days before applying — new inquiries and new debt both lower your score and increase your DTI
A rapid rescore is one of the most underused tools in the VA loan process. If you paid off a credit card balance yesterday, your credit report will not reflect it for 30–45 days under normal reporting. A rapid rescore pushes the update through in days, letting your lender resubmit to AUS with a higher score immediately.
Common Mistakes That Hurt AUS Outcomes
Most AUS problems are preventable. The file does not fail because of some hidden flaw in the system — it fails because of how the application was prepared or what information was included.
Avoidable Errors
- Not disclosing all income — omitting BAH, BAS, disability income, or a second job makes your DTI look higher than it actually is
- Overestimating variable income — AUS uses the lower of 2-year average or current income for overtime, bonuses, and commission; projecting future earnings does not work
- Ignoring small collections — even a $300 unpaid collection can suppress your FICO by 30+ points and trigger a Refer
- Incorrect liability reporting — forgetting a car payment, student loan, or alimony obligation that shows on your credit report creates a DTI mismatch that AUS flags immediately
- Applying during a job transition — AUS needs stable, documented income; if you just started a new job without 30 days of pay stubs, the file will likely Refer
The most expensive mistake is applying to a lender who will not manually underwrite a Refer. If your file gets a Refer and that lender cannot process it, you have to start over with a new lender — new credit pull, new application, new timeline. Choose a lender who handles both AUS Approve and manual underwriting files before you apply.
What If Neither AUS Nor Manual Underwriting Works?
In rare cases, neither AUS nor manual underwriting produces an approval. This usually means the file has a fundamental issue — active foreclosure within the past 2 years, insufficient entitlement, or income that cannot be documented to meet residual income thresholds.
When this happens, there are two realistic paths forward. First, address the specific disqualifying factor — pay down debt, wait out a seasoning period, establish additional income documentation — and reapply in 3–6 months. Second, consider an FHA loan as a temporary bridge. FHA allows scores as low as 580 with 3.5% down, has more flexible DTI allowances, and lets you build 12 months of payment history before refinancing into a VA loan later.
The Bottom Line
AUS is the starting point for every VA loan — not the finish line. An Approve/Eligible puts you on the fastest path to closing with minimal documentation. A Refer routes your file to manual underwriting, where compensating factors like stable rent history, strong residual income, and reserves can still get you approved. The key is working with a lender who submits your file correctly, includes all income sources, and has the ability to manually underwrite if AUS says Refer.
Credit score minimums, DTI caps, and reserve requirements beyond what AUS conditions are lender overlays — not VA rules. If one lender tells you no, it may mean their overlays are too restrictive for your file, not that you are ineligible for a VA loan. Get a second opinion from a lender who specializes in VA files and knows how to structure applications for the best possible AUS result.

Frequently Asked Questions
What is AUS on a VA loan?
AUS (Automated Underwriting System) is the digital platform that evaluates your VA loan application. It pulls your credit, calculates your DTI, and returns a finding — Approve/Eligible, Refer, or Ineligible — within minutes of submission.
Can I get a VA loan without AUS approval?
Yes. If AUS returns a Refer, you can still be approved through manual underwriting. A human underwriter reviews your compensating factors — stable rent history, reserves, residual income — and makes a decision. Many Veterans close this way.
What credit score is needed to pass AUS for a VA loan?
The VA has no minimum credit score. Most AUS models approve files at 620+ with reasonable DTI. Below 620, the file typically receives a Refer and goes to manual underwriting. The 620 threshold is a lender overlay, not a VA requirement.
Does BAH count as income when AUS evaluates my file?
Yes. BAH is non-taxable income that can be grossed up by 25%. If your BAH is $2,000/month, your lender can count $2,500/month as qualifying income, lowering your effective DTI.
How long does an AUS decision take?
AUS returns a finding within minutes of submission. The lender enters your application data, submits to DU or LPA, and receives the result almost immediately. The timeline from AUS approval to closing is typically 25–35 days.
Is manual underwriting harder than AUS?
Manual underwriting requires more documentation — 2 years of tax returns, 2 months of bank statements, verification of rent, and detailed income records. It takes longer but is not inherently harder. The underwriter evaluates the full file and applies judgment that AUS cannot.
Can I get preapproved if my file received a Refer?
Yes. A lender who offers manual underwriting can preapprove you after reviewing your compensating factors. The preapproval letter will note that the file requires manual underwriting, but sellers generally accept it the same as an AUS-backed preapproval.
