Manual underwriting: How it works for mortgages

Manual underwriting is a mortgage approval process where a person reviews your financial paperwork and information instead of a computer algorithm. If you have a thin credit file, a high debt-to-income ratio (DTI), past bankruptcy, or self-employment income, then your lender may require manual underwriting.

Key takeaways:

• Manual underwriting involves a human underwriter who evaluates your full financial picture.
• Manual underwriting is designed for borrowers living debt-free, those with no traditional credit score, high DTI ratios, or past financial setbacks like foreclosure or bankruptcy.
• Because an underwriter cannot rely solely on a standard credit score, you will need to provide extensive proof of income, asset reserves, and 12 to 24 months of alternative credit payments.

What is manual underwriting for a mortgage?

When you apply for a mortgage, your lender reviews your finances to make sure you can afford to repay it. This is called underwriting.

Lenders usually use a desktop underwriting system, which runs your information through a computer algorithm to find out if you meet the requirements.

If your finances are unusual in some way, like you have a thin credit file, a high DTI, or poor credit, the algorithm likely will deny you.

However, that doesn’t necessarily mean you can’t afford a mortgage. To fairly evaluate your finances, lenders will use manual underwriting, and a human being capable of understanding the nuances of your financial situation will evaluate your application.

This can be a helpful option for borrowers who have the income and stability to keep up with mortgage payments, but who don’t fit the typical profile of a qualified borrower.

Manual underwriting vs. automated underwriting

Even with advances in financial technology, there’s a vital need for human involvement and insight in the mortgage process.

How automated underwriting works for mortgages

An automated underwriting system (AUS) is a computer application that compares your financial information with standard guidelines to decide whether you meet the lender's minimum requirements.

With just a small amount of inputted information – like your Social Security number, income, and address – the system can evaluate your credit history and debt load. After the program reviews the data, your lender briefly verifies the result and issues an approval decision.

Lenders use automated underwriting because it’s fast and cost-efficient.

How manual underwriting works for mortgages

Manual underwriting takes more time than automated underwriting and requires significantly more documentation. However, if you have a unique financial situation, manual underwriting can improve your chances of getting approved for a home loan.

Approval timeframe

While an automated system can return a decision in minutes, manual underwriting typically adds several days or weeks to the overall loan approval process.

Knowing how long underwriting takes can help you set realistic expectations for your closing timeline.

Documents required

Because the underwriter cannot rely on an automated credit assessment, you will need to provide a comprehensive document package.

Expect your lender to ask you to provide up to 24 months of bank statements, income tax returns, W-2 forms or profit-and-loss statements, proof of continuous employment, asset verification, and documentation for alternative credit lines.

When is manual underwriting done?

A lender might choose to manually underwrite a loan under a few specific circumstances.

No credit score or thin credit file

Paying back traditional debt is the foundation of a high credit score. But if a borrower chooses to live debt-free, or if they are a young adult or recent immigrant, they may have a thin credit file or no credit score. Manual underwriting allows lenders to assess their creditworthiness.

Automated underwriting returns a "Refer" or "Caution" result

When an automated underwriting system cannot approve an application, it generates a result labeled "Refer" or "Caution." This signals to the lender that the file must be transferred to a human underwriter for a manual review.

High DTI

If you have a high DTI, automated underwriting may automatically reject the application. However, if you can demonstrate that your debt is temporary, manageable, or a routine part of your business endeavors, manual underwriting can evaluate your complete income stream to help you secure mortgage approval.

Past bankruptcy or foreclosure

Buying a home with a bankruptcy or foreclosure within the past 1 to 4 years can raise a red flag for automated algorithms. Manual underwriting allows a human reviewer to look beyond the event, evaluate a written explanation, and consider compensating factors like a high income, substantial savings, or pristine recent payment history.

Self-employment

If you’re self-employed or own a small business, your income may fluctuate or appear lower on paper due to tax deductions. An automated computer program may misinterpret these figures, whereas a human underwriter can review profit-and-loss statements to verify your true financial strength.

Manual underwriting requirements

To succeed in manual underwriting, borrowers must meet specific financial benchmarks that prove their ability to handle monthly mortgage payments without relying solely on a traditional credit score.

Alternative credit lines

If you lack a standard credit score, manual underwriting can review your alternative credit history. You will typically need to document 12 to 24 months of consistent, on-time payments for recurring non-debt expenses, such as:

• Rent and housing payments
• Utility bills (electric, water, gas)
• Cell phone and internet services
• Auto and health insurance premiums

Stable employment

Underwriters look for a predictable, ongoing source of income to ensure you can afford your loan over time. Borrowers generally need to demonstrate at least 2 years of continuous, stable employment with the same employer or within the same line of work.

Income, assets, and cash reserves

Having strong financial reserves is critical during a manual review. Underwriters evaluate your liquid assets to verify that you can comfortably cover your down payment, closing costs, and post-closing mortgage obligations. Depending on the loan type, down payment expectations range from 3% for conventional fixed-rate loans¹ and 3.5% for government-backed home loans to 10% or more for jumbo loans.

Compensating factors

Compensating factors are financial strengths that offset potential risks in your application, such as a high DTI or past credit blemishes.

Strong compensating factors include:

• Documented liquid cash reserves equal to 3 to 6 months of total monthly mortgage payments.
• Minimal increase in your new monthly housing payment compared to your previous rent (often less than $100 or 5%).
• Verified residual income left over after all monthly debts and living expenses are paid.

Manual underwriting by mortgage type

Your underwriting options and eligibility rules will vary based on the type of mortgage program you’re applying for.

Conforming conventional mortgages

A conforming conventional loan is originated by a private lender and sold to government-sponsored enterprises like Fannie Mae or Freddie Mac. A standard conforming loan uses Fannie Mae and Freddie Mac automated underwriting systems for primary evaluations. While lenders are permitted to assign conventional loan applications to manual underwriting under strict guidelines, they are not obligated to do so.

Jumbo loans

Jumbo loans are nonconforming loans that exceed standard conforming loan limits. Because jumbo loans represent higher financial amounts, lenders frequently incorporate manual underwriting into their evaluation process – especially for high-value properties.

Government-backed mortgages

Lenders offering government-backed home loans – such as FHA loans, VA loans, or USDA loans – must follow specific agency guidelines regarding manual underwriting.

FHA loans

Following the FHA loan process requires meeting strict agency guidelines. FHA rules require applications to be manually reviewed if the borrower's credit score falls below 620 or if their DTI exceeds 43%.

FHA loans can be manually approved with credit scores as low as 580,² or with a DTI up to 50%, provided the applicant makes a higher down payment or presents strong HUD-approved compensating factors:

• Verified cash reserves. Documented reserves equal to three monthly payments for one- to two-unit properties, or six monthly payments for three- to four-unit properties.
• Minimal payment shock. A new mortgage payment that is no more than $100 or 5% higher than their previous 12-month housing payment history, with no late payments.
• Significant residual income. Discretionary income remaining after all primary expenses are satisfied.

VA loans

VA loan applications are among those most frequently referred for manual underwriting.³ Because VA loans exist to support veterans, active-duty military personnel, and eligible surviving spouses, lenders work diligently to find solutions for qualifying applicants. Borrowers undergoing manual underwriting for a VA loan may need to meet tighter DTI limits and prove adequate residual income.

USDA loans

USDA loan applications designed for rural homebuyers that are flagged or rejected by automated software can be resubmitted for manual underwriting. Borrowers also can formally request a manual review to ensure their unique income stream is properly evaluated.

Rocket Mortgage currently doesn’t offer USDA loans.

How does a manual underwriting mortgage work?

Here is what you can expect step-by-step when your lender manually underwrites your mortgage application:

1. Collection of your financial information

Ask your mortgage loan originator to help you assemble the complete document package required for underwriting.

You will be asked to gather and submit an extensive collection of items, including:

• Up to 12 to 24 months of personal and business bank statements
• Two years of personal tax returns and W-2s
• Verification of Employment (VOE) from your employer
• Recent pay stubs showing consistent, year-to-date earnings
• Statements for retirement, investment, and liquid savings accounts
• Ownership documentation for significant assets
• Year-to-date profit-and-loss statements and balance sheets if self-employed

Gathering these items before you officially apply will help streamline your review.

2. Review of your credit report

During a manual review, the underwriter looks past your numerical credit score to analyze your payment habits. They examine:

• Good debt. Installment accounts with consistent, on-time payment histories, such as student or auto loans.
• Revolving debt. Outstanding credit card balances and total credit utilization.
• Delinquencies. Late payments, collection accounts, or public records.

If you have a thin credit file, the underwriter will verify your alternative credit lines, such as rent or utility statements.

If your record shows past financial setbacks, submitting a clear letter of explanation gives you the chance to provide the context behind the event.

3. Review of your income and assets

Your underwriter compares your documented gross monthly income against your proposed mortgage payment to ensure long-term affordability. Lenders may call your employer directly to confirm employment stability, average hours, and bonus structures.

Underwriters also verify your liquid assets to confirm you have enough funds to cover your down payment and closing costs while leaving a comfortable cash buffer behind.

4. Review of your debt and liabilities

The underwriter calculates your DTI by dividing your total monthly recurring debts by your gross monthly income. While automated guidelines generally cap DTI around 36% to 43%, manual underwriting allows for DTIs up to 50% if the application is supported by compensating factors. Underwriters also account for nondebted financial obligations, including child support, alimony, or tax payment plans.

5. Review of your collateral

The underwriter also evaluates your collateral, which includes your property's appraised value and your cash down payment. Depending on the loan type and property evaluation method, lenders may use automated evaluation models or a desktop appraisal alongside physical inspections to verify a home’s fair market value.⁴

Making a larger down payment reduces risk for the lender and can help secure better mortgage rates. The underwriter will trace large or sudden bank deposits back to their source to ensure funds come from personal savings, liquidated assets, or documented gift funds rather than unauthorized loans.

6. Final decision

Once the review is complete, the underwriter issues one of three formal decisions:

1. Approval. Your application meets all agency and lender requirements.
2. Denial. Your application does not meet minimum risk guidelines. Knowing what to do if your mortgage application is denied can help you adjust your strategy and work toward qualifying in the future.
3. Suspension with contingencies. Your loan is conditionally approved pending additional documentation or explanation.

Manual underwriting pros and cons

Evaluating a mortgage application through human review offers clear advantages alongside a few key trade-offs.

Pros of manual underwriting

• Opens doors for nontraditional borrowers: Provides a realistic path to homeownership for individuals living debt-free, those without credit scores, or self-employed workers.
• Considers context: Human underwriters can weigh individual circumstances, life events, and letters of explanation behind past financial blemishes.
• Flexible DTI allowances: Manual underwriting allows a higher DTI when backed by compensating factors like cash reserves.

Cons of manual underwriting

• Requires extensive paperwork: Borrowers must submit significantly more documentation, statements, and alternative credit records.
• Takes more time: Manual verification of documents inherently extends the processing timeline compared with automated software.
• Stricter reserve requirements: Lenders often mandate higher down payments and several months of documented post-closing cash reserves.

FAQ

Here are answers to common questions about manual underwriting.

Do banks still do manual underwriting?

Yes, mortgage lenders and banks still offer manual underwriting. While automated systems process most mortgage applications, lenders rely on manual underwriting to evaluate various types of loans and applicants with unique financial situations.

Is manual underwriting more difficult to get approved?

Manual underwriting is not necessarily more difficult, but it is more rigorous. Because an underwriter cannot rely on an automated credit score, you must provide more documentation to verify your payment history, employment stability, and financial reserves.

The bottom line: Manual underwriting gives borrowers a human review

Manual underwriting offers a personalized mortgage review process for buyers with unique financial circumstances. While it requires a greater investment of time and paperwork than automated systems, it creates a clear path to homeownership for individuals carrying higher DTI ratios, those living debt-free, self-employed workers, or those recovering from past financial setbacks.

By taking a holistic view of your financial picture, manual underwriting gives lenders the context necessary to confirm that you can comfortably afford your home.
