How an FHA Loan Lender Weighs Credit and Debt on a Borrower

The Quick Read: The lender reads your credit history and your monthly debts together, not as two separate tests. Credit shows how you have handled past obligations. Debt-to-income shows how much room your budget has for a new one. Strong credit can make a heavy debt load easier to accept, and thin or damaged credit makes the same debt load look riskier. Every program figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.

What Is the Lender Actually Deciding?

The lender is deciding one thing: whether you will repay this loan on time, given everything in your file. Each part of the file answers a different piece of that question.

Credit and debt get the most attention from borrowers, and for good reason. They are the two inputs you can see and change before you apply.

Across the wholesale programs Lendmire places files with, FHA is the program most often used by buyers with modest savings or a bruised credit report. The FHA loan programs allow maximum financing of 96.5% of the home’s value, with a 3.5% minimum investment, at a decision score of 580 or higher. The program is built for borrowers who do not look perfect on paper. That flexibility has limits, and the limits show up in how credit and debt are read.

The home must be your principal residence, from one to four units. A non-occupant co-borrower is allowed. That detail matters later, because a co-borrower’s credit can change how the file is reviewed.

How Does the Lender Read Your Credit?

The lender reads your credit as behavior over time, not as one number. The score gets you in the door. The payment pattern behind it decides how the file feels to an underwriter.

The score is a decision score. The lender pulls a traditional credit report and picks one score per borrower. If three different scores come back, the middle one is used. If two come back, the lower one is used. With more than one borrower on the loan, the lowest borrower’s score governs the whole file. That surprises many couples. A strong score on one spouse does not rescue a weak score on the other.

HUD recently updated its method for choosing this score so FHA can accept newer credit score models. HUD’s Mortgagee Letter on the minimum decision credit score lays out the lowest-borrower rule and says the change will be folded into the handbook. Treat the method as changing, not settled.

HUD’s own rules allow lower scores than most lenders accept. HUD has a tier for scores of 500 to 579 that requires a 10% minimum investment. The wholesale programs Lendmire works with start at 580, so that tier is a HUD rule the network does not reach. Lenders set their own higher floors too.

Recent behavior outweighs old behavior. An underwriter looks hardest at the last year or two of payments. A single slow payment from long ago reads differently from a cluster of late payments last spring. Mortgage or rent payment history gets special attention, because it is the closest thing to the payment you are about to take on.

Here is how common credit events tend to read:

HUD’s waiting periods are two years from a Chapter 7 discharge and three years from a foreclosure. Those are HUD rules, not a promise from any lender, and a lender can still ask for more.

Thin or no credit. Some buyers have no credit score at all, or too few accounts to score. These borrowers remain eligible for maximum financing under FHA, but the file must be manually underwritten. The lender builds a history from non-traditional sources such as rent, utilities or insurance, and each one must be independently verified. HUD’s handbook also gives some first-time buyers credit for documented on-time rent, but only under specific conditions. Expect to hand over more paperwork, not less.

Self-employed buyers face a similar paperwork load. Lendmire’s piece How a Self-Employed Mortgage Lender Weighs Your Credit Score covers that side in more depth.

How Does the Lender Count Your Debt?

The lender counts your debt by adding up monthly payments and dividing them by your gross monthly income. Gross means before taxes. The Consumer Financial Protection Bureau describes this ratio the same way and notes that limits vary by loan product and lender.

FHA looks at two versions of that ratio.

• Housing ratio. The new mortgage payment (principal, interest, taxes, insurance and FHA mortgage insurance) divided by gross income.
• Total ratio. The housing payment plus every other monthly debt, divided by gross income.

The base pair on FHA is 31/43, meaning housing at 31% and total debt at 43% of gross income, with no compensating factors. With documented compensating factors, the pairs can stretch up to 40/50 at the top credit tier. For most files, the automated finding governs, and it can approve ratios outside those base numbers.

Run the numbers on a simple picture, using percentages only. Say the new housing payment takes 28% of your gross income. A car loan, a card minimum and a student loan add another 12 points. Your total ratio is 40%. That sits inside the base 43% limit on paper, and the credit history behind it decides how it is read.

Which debts count. The lender finds your debts two ways: the credit report and your application. Each debt type gets its own treatment.

Student loans deserve a note. FHA counts them even when payments are paused, and the lender may figure a payment from the balance when the report shows none. The exact method is set by HUD guidance that changes, so ask the loan officer how it applies to your loans.

Collections are the most misunderstood item. Many buyers believe every collection must be paid off. HUD’s published guidance does not say that. Under HUD’s FHA Q&A on collections, the lender looks at the total of non-medical collections across all borrowers. Once that total reaches $2,000, the lender needs one of three things: proof the collections were paid in full, a payoff statement at settlement, or a payment arrangement with the creditor. If none is available, the lender counts 5% of each collection’s balance as a monthly payment in your ratio.

That 5% is a paper payment. You may never make it, but it raises your total ratio anyway. The same Q&A says a non-borrowing spouse’s collections count in community property states, unless state law excludes them. HUD Mortgagee Letter 2013-24 sets out the same capacity analysis and the medical exclusion. Note that the Q&A page is older, so the current handbook wording is the final word on details.

Judgments are stricter. HUD’s guidance generally requires them to be paid off before the loan is eligible, with an exception for a documented payment arrangement.

How Are Credit and Debt Weighed Together?

They are weighed as a pair, and that is the part most explainers skip. The same ratio reads differently depending on the credit history behind it.

Picture two buyers, both at a 43% total ratio. Buyer A has a decision score well above the minimum, a clean twelve months of payments and a few months of cash reserves. Buyer B sits near the minimum score, with two late payments in the past year and almost no cash left after closing.

The lender sees two different risks. Buyer A has a heavy but well-managed load. Buyer B has a heavy load and a record of stumbling under it. Buyer A may get an automated Accept. Buyer B may get a Refer, a manual review and a request for written explanations.

The reverse also holds. A modest ratio with a thin, unproven credit file still triggers extra checks, because the lender has little evidence of how you handle payments. Credit that is strong offsets debt, and debt that is light offsets weak credit, but only to a point. Neither one fully covers for the other.

Automated Review Versus Manual Review

An automated underwriting system runs first, and a person steps in only when it says so. Here is the usual order:

1. The credit pull. The lender pulls a traditional credit report and picks each borrower’s decision score.

2. The debts are built. The lender reviews credit inquiries. New debt from recent inquiries goes into your ratios. The lender also checks that you did not borrow to fund your cash to close.

3. The automated run. FHA’s scorecard, called TOTAL Mortgage Scorecard, returns an Accept or a Refer.

4. Manual underwriting, if needed. A Refer sends the file to an underwriter who weighs the ratios, the credit history and the compensating factors by hand.

5. The final decision. The lender reconciles credit, income, assets and property. Conditions must clear before the file is final.

This structure follows HUD Handbook 4000.1, which has separate sections for the scorecard path and manual underwriting.

Several things push a file to manual review. A Refer from the system is the most common one. A very recent run of late mortgage payments can downgrade an Accept to a Refer. A cash-out refinance faces a stricter payment-history test than a purchase. Borrowers with no credit score, or a score only on a non-occupying co-borrower, are also reviewed manually.

Manual does not mean denied. It means a human reads the story behind the numbers.

Why do published ratio limits disagree? Because they describe different paths. A manual file works from a ratio matrix tied to score and compensating factors. An automated Accept can approve a file with ratios beyond that matrix, because the scorecard weighs the whole file. Then a lender’s own overlay can sit on top of both. When you see two different “maximum” numbers online, they usually answer different questions.

Compensating Factors

A compensating factor is a documented strength in your file that offsets a risk. In manual underwriting, these are what move you from the base 31/43 pair toward 40/50.

Common examples include:

• Cash reserves after closing
• A long, steady job history
• A small increase in housing cost compared with what you pay now
• Substantial documented additional income
• Minimal other debt

“Documented” is the key word. A lender cannot credit a strength it cannot prove. Reserves need bank statements. Job stability needs employment records. Plan to gather these before the underwriter has to ask.

Meeting the Minimum Is Not the Same as Approval

Meeting a program minimum makes you eligible to be considered. It does not make approval automatic. Individual lenders may apply stricter standards than HUD’s minimums, and those are called overlays. A lender might set a higher score floor or limit the ratio it will accept on a manual file.

This is where a broker earns the title. Lendmire arranges FHA loans through wholesale lenders, and each lender’s overlays differ. Matching a file to a lender whose standards fit the borrower can matter as much as the file itself. Every outcome remains subject to lender guidelines, credit approval and full file review.

What to Fix Before You Apply

Fix the item that moves the part of the file the lender cares about most. Different problems call for different levers.

Start early. Score changes take time to show up, and a new account opened during the process can add debt to your ratios. Lenders also review inquiries and ask about new debts. Avoid financing furniture or a car while your file is open.

Disputed accounts need care too. If a dispute lowers the payment used in your ratio, you must document the lower payment.

Key Terms Defined

Decision score: the single credit score FHA uses for the loan, taken from the lowest-scoring borrower.

Debt-to-income ratio (DTI): your monthly debt payments divided by your gross monthly income.

Housing ratio: the new housing payment divided by gross income, sometimes called the front-end ratio.

Total ratio: housing plus all other monthly debts divided by gross income, the back-end ratio.

Automated underwriting: a scoring system that reviews your file and returns an Accept or a Refer.

Manual underwriting: a person reviews your file by hand, usually after a Refer.

Compensating factor: a documented strength that offsets a risk in the file.

Overlay: a lender rule stricter than the program minimum.
