Manual Underwriting: When the Computer Says No

Automated underwriting returns a refer, and most lenders stop there. On government and non-agency programs, a human underwriter reading the whole file is a documented path.

Quick answer

Saxton Mortgage will. At least one FHA program we offer manually underwrites loans that receive a Refer from TOTAL Scorecard, loans with non-traditional tradelines or borrowers without a credit score, and Accept files that the underwriter downgrades to a Refer. On a manual file, credit is acceptable when all housing and installment payments, including rent and utilities, were made on time for the past 12 months, with no more than two 30-day late mortgage or installment payments in the past 24 months.

A refer is not a denial

It is a routing decision, and there is somewhere for the file to go.

  • Government programs explicitly permit manual underwriting when the automated system returns a refer or when a downgrade is required.
  • Many non-agency and jumbo programs skip the automated system entirely. Their guidelines state that all loans are manually underwritten.
  • Manual files run on published ratio tiers. On at least one government program the base tier is 31/43, one documented compensating factor moves it to 37/47, and two move it to 40/50.
  • Compensating factors are named in the guidelines, not invented at the desk. Reserves, residual income, a small payment increase and no discretionary debt all appear by name.
  • On at least one government program a credit score of 500 to 579, or no credit score at all, can still be manually underwritten, with ratios capped at 31/43.
  • Conventional conforming loans are the exception. Several guidelines state that manually underwritten conventional loans are ineligible.

How The Ratio Ladder Works

On government financing the tiers are written down, which means you can work toward them.

The base tier for a manually underwritten government file requires no compensating factors at all. Moving up a tier requires one documented factor: three months of payments in reserve for a one-to-two unit property or six months for three-to-four units, or a new housing payment that is barely higher than your current one paired with a clean twelve-month housing history, or residual income measured against the published regional table.

A separate tier is unlocked by having no discretionary debt, defined precisely: the housing payment is your only open account carrying a balance that is not paid off monthly, your credit report shows accounts open at least six months, and you can document those accounts being paid in full every month for the past six. The top tier requires two of the compensating factors rather than one.

On VA financing the structure differs but the logic is the same. A ratio above forty-one percent requires residual income at a set premium above the requirement, and pushing higher additionally requires no housing lates in the last twelve months and at least two months of reserves from verified assets, with gift funds specifically excluded from counting as reserves.

Reviewing loan paperwork at a table

What actually gets you approved manually

Six things that decide a manual file.

Reserves

The single most portable compensating factor. Three months of payments in the bank after closing appears in the FHA tier table, the rural housing waiver criteria and the VA structure. If you can add reserves before applying, that is the highest-leverage move available.

Residual Income

What is left after every obligation is paid. It unlocks a higher FHA tier and it is the mechanism for exceeding the standard VA ratio. It rewards a borrower with modest debts and a real income, which an automated score may not.

A Small Payment Increase

If your new housing payment is close to what you already pay and you have a clean twelve-month housing history, that combination counts as a compensating factor by name. It is why documenting your current rent properly matters.

No Discretionary Debt

A precisely defined factor: the mortgage is your only account carrying a balance, and everything else is paid in full monthly with at least six months of history. The trap is that you have to have those other credit lines. A borrower with no established credit besides the housing payment does not qualify under this criterion. Rare, but decisive when it applies.

Long Employment

Two years continuously with the same primary employer is a named compensating factor on the rural housing waiver criteria, and it has to be true of every employed applicant, not just one. It does not apply to self-employed applicants. On at least one program the waiver also requires a credit score of 680 or above, and applicants qualifying on nontraditional credit are not eligible for it at all.

Choosing A Program That Permits It

The most important factor of all. Conventional conforming programs largely prohibit manual underwriting, while government and non-agency programs permit or require it. A refer on a conventional file often just means the loan belongs somewhere else.

Frequently Asked Questions

Questions about manual underwriting.

Saxton Mortgage will. At least one FHA program we offer manually underwrites loans that receive a Refer from TOTAL Scorecard, loans with non-traditional tradelines or borrowers without a credit score, and Accept files that the underwriter downgrades to a Refer. On a manual file, credit is acceptable when all housing and installment payments, including rent and utilities, were made on time for the past 12 months, with no more than two 30-day late mortgage or installment payments in the past 24 months.

Not necessarily. On government programs a refer routes the file to manual underwriting rather than ending it. Many non-agency programs never run an automated system at all. What is true is that conventional conforming loans largely cannot be manually underwritten.

Named triggers include recent mortgage lates, fewer than three consecutive payments since a forbearance ended, undisclosed mortgage debt the automated system never saw, disputed accounts, and any information in the file that the scorecard cannot evaluate.

Yes, at the base tier. A manually underwritten government file starts at tighter ratios than an automated approval and works upward from there as you document compensating factors. On at least one government program the ladder is 31/43 at the base, 37/47 with one documented factor, and 40/50 with two. On the rural housing program the purchase base is 29/41, moving to 32/44 with a credit score of 680 or above plus one documented factor.

Guidelines name them: reserves, residual income above the regional requirement, a minimal increase in housing payment with clean history, no discretionary debt, long employment, significant additional income not counted as effective income, conservative use of credit, and substantial liquid assets among others.

Generally yes. A person is reading the whole file rather than a system returning a decision, and conditions tend to be more specific. Well-organized documentation shortens it considerably.

It can be. On at least one government program the manual underwrite path carries a lower credit score floor than the automated path at the same loan amount, paired with a tighter maximum ratio.

Usually. Guidelines state that a borrower without a credit score is reviewed with nontraditional credit and the loan is manually downgraded, with its own ratio cap. On at least one government program that cap is 31/43, and only the income of borrowers who will live in the home and are obligated on the mortgage counts toward it.

Manual underwriting is when a human underwriter reads and approves your file instead of an automated system doing it. The automated system compares your file to a set of rules and returns an approval or a refer. A refer is not a denial, it just means the software will not make the call. On government and non-agency programs a manual underwrite is a documented, published path to approval with its own ratio caps and its own list of compensating factors.

AUS stands for automated underwriting system, the software that reads a loan file first. It returns either an approval or a refer. A refer means the system is declining to decide, not that the lender has declined you. A file can also be downgraded to a manual underwrite by the lender even after an approval, usually because something in the file needs a person to weigh it.

Thin credit, meaning few accounts or a short history, is one of the situations manual underwriting exists for. An underwriter can look at rent, utilities and other non-traditional payment history, at your reserves and at your residual income, none of which an automated system weighs the same way. Every borrower still needs at least the minimum the program requires.

Manual underwriting availability, qualifying ratio tiers, compensating factor requirements and credit score minimums vary by loan program and investor and are subject to change. Several conventional conforming and jumbo programs do not permit manually underwritten loans. Not all applicants will qualify. This is not a commitment to lend.
