The Quick Read: A simple refinance is a full-underwriting product, so a high debt-to-income ratio and student loans both get counted. HUD requires the lender to include every student loan in your liabilities, whatever its payment status. The automated finding, not a single ratio cap, usually decides whether a high-DTI file clears. If the ratio is the problem, a different FHA refinance type may fit better, and that choice is the real decision.
What Is an FHA Simple Refinance?
An FHA simple refinance is a no-cash-out refinance of an existing FHA-insured loan. All proceeds pay off the old FHA lien and the transaction costs. HUD’s Handbook 4000.1 glossary defines it that way.
Refinance savings and break-even estimate
The starting figures are an example value with a balance in proportion and a placeholder for costs. Replace them with yours, and enter the current rate from your statement.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

It is not a Streamline. That is the mix-up that derails the most borrower conversations. A Streamline limits credit documentation and underwriting. A simple refinance does not. Across the wholesale programs Lendmire places files with, the simple refinance means a full look at income, debts, credit and an appraisal.
The name causes trouble because search results use "simple" and "streamline" as if they were the same thing. They are different products with different tests. Keep them apart from the first phone call.
Lendmire's FHA loan programs cover both paths, and the lender, not the broker, makes the final eligibility decision.
Key Terms Defined
Simple refinance: A no-cash-out refinance of an FHA loan that is fully underwritten and appraised.
Streamline refinance: An FHA-to-FHA refinance with no appraisal and a limited credit review, built around a net tangible benefit.
DTI (debt-to-income ratio): Your total monthly debt payments divided by your gross monthly income, as the CFPB defines it.
Automated finding: The result from FHA's automated underwriting scorecard, which recommends a level of review. "Approve/Eligible" is the usual clean path. "Refer" sends the file to manual underwriting.
Compensating factors: Documented strengths, such as reserves or a strong payment history, that can support a higher ratio.
Net tangible benefit: The test that a Streamline must pass so the borrower actually gains from the new loan.
How Is the Loan Underwritten, Step by Step?
The loan works through six checks. Each one can add a document request, so knowing the order helps you prepare.
1. Existing loan and occupancy. The current loan must be FHA-insured, and the standard simple refinance is for a home you live in as your principal residence. The lender may ask for employment documents or utility bills to show you live there. A rental or second home does not sit in this lane, because occupancy decides the leverage.
2. Application and credit pull. Unlike a non-credit-qualifying Streamline, the lender pulls your credit and underwrites you as a borrower. The wholesale programs Lendmire works with start at a 580 decision score for FHA purchase files. Individual lenders may set their own higher floors on a refinance.
3. Debt count, including student loans. Every liability goes into the ratio. More on this below, because it is where most high-DTI files change shape.
4. Automated underwriting. The scorecard looks at overall creditworthiness and recommends how much documentation the file needs. A clean finding keeps the file moving. A "Refer" finding means manual underwriting, which uses tighter ratio rules and wants compensating factors.
5. Appraisal. A simple refinance needs one. This is the biggest practical difference from a Streamline, which reuses the prior value. The appraised value limits the new loan amount, and it limits how much of the closing costs can be rolled in.
6. Maximum loan amount. FHA rate-and-term refinancing with an appraisal reaches 97.75% LTV on a principal residence occupied for the previous twelve months. County loan limits apply and change every year. Mortgagee Letter 2010-24 shows the same 97.75% CLTV figure for no-cash-out refinances. Current Handbook text governs, and the lender confirms it on your file. Final terms vary by lender and program and depend on a full review of the property, leverage and credit.
How Does FHA Count Student Loans in DTI?
FHA counts every student loan. The lender must include all student loans in the borrower's liabilities, regardless of payment type or status. Deferred and forbearance loans are not excluded.
HUD Mortgagee Letter 2021-13 is the policy change behind this. It sets how student-loan payments are calculated, and it applies across FHA's forward programs. The one exception is the non-credit-qualifying Streamline, which does not evaluate the borrower's debts at all.
In practice the treatment falls into a few buckets:
| Student loan status | How the lender usually treats it |
|---|---|
| Standard repayment | Uses the documented payment |
| Income-driven, payment above zero | Can use the documented payment |
| Income-driven, payment of zero | Placeholder calculation applies |
| Deferred or forbearance | Still counted; placeholder calculation applies |
The placeholder is a small percentage of the outstanding balance. Do not confuse a half percent with five percent. That mix-up scares borrowers for no reason.
If the payment used is lower than the credit report shows, the lender needs written documentation. That means a letter from the servicer stating the actual monthly payment, payment status, balance and terms. Gather that letter before you apply. Missing servicer paperwork is the most preventable gap on these files.
What Counts as a "High" DTI for This Loan?
There is no single FHA ceiling. The CFPB notes that different loan products and lenders have different DTI limits, which fits what shows up in files.
Across the wholesale programs Lendmire places FHA loans with, the base pair is 31/43. That is housing ratio over total ratio, with no compensating factors. Documented compensating factors can reach 40/50 at the top tier. The automated finding governs most files, which means two borrowers with the same ratio can get different outcomes.
Here is how that plays out:
- At or under the base pair. Rarely a ratio problem. Credit and appraisal are the next things to check.
- Between the base pair and the top tier. Strengths decide it. Reserves, a clean payment history and stable employment documentation help the file.
- Above the top tier. Usually a decline or a restructure, not a documentation fix.
Lenders can also add overlays that are stricter than HUD. A file one lender turns away can clear with another. That is a reason to run the same file through more than one wholesale channel before drawing conclusions.
One more point. The CFPB's Ability-to-Repay summary shows lenders must consider DTI or residual income, but its compliance guidance says the rule sets no specific threshold. FHA's ratios come from HUD, not from the CFPB. The old 43% General QM number is not the FHA cap, though it shows up in many articles as if it were.
Where Does a Refinance Lower the Ratio on Its Own?
A refinance that lowers the housing payment can offset the student-loan placeholder. The ratio moves even though your cash flow did not. That is the quiet upside.
Picture a homeowner whose student loans sit in forbearance with a zero payment. The credit report shows no payment, but the lender must still add a placeholder. That pushes the DTI up and can turn an affordable refinance into a "Refer" finding. If the new housing payment is lower than the old one, the total ratio can come back down enough to clear.
This is mechanics, not a promise. Whether it works depends on the new term, the mortgage insurance and the balance. FHA charges an upfront premium of 1.75% of the base loan, which can be financed. The annual premium runs between 0.15% and 0.75% of the balance depending on term, loan amount and LTV. On a thirty-year loan above ninety percent LTV, the annual premium lasts for the term. At or below ninety percent it ends after eleven years. Both feed the new payment, so they feed the ratio.
Where Does the General Rule Break?
Five edge cases come up again and again.
The Streamline alternative. If DTI is the obstacle, the non-credit-qualifying Streamline does not evaluate the borrower's debts. The FHA Streamline refinances an existing FHA loan with no appraisal, a limited credit review and a net tangible benefit, and the mortgage insurance premium continues. It has its own conditions. It is not a workaround for everyone, and it is wrong for a borrower who needs to take cash out.
Deferred loans. The old twelve-month deferral exclusion is gone. A loan that starts payments next year still counts today.
Income-driven plans. A documented payment above zero can replace the placeholder. A zero payment still triggers it. Get the servicer's letter in writing.
Existing second liens. HUD's older material says a subordinate lien can stay if the combined balance remains within the CLTV limit. The second-lien holder has to agree to subordinate.
Short occupancy. The 97.75% figure assumes the home was your principal residence for the previous twelve months. Shorter occupancy usually lowers the maximum. Lenders vary on how much, so ask early.
What Gets a High-DTI File Stuck?
Most problems are paperwork, not rules. These are the common ones.
- Stale or missing servicer letters. The credit report shows a payment that is higher than the real one, and no letter supports the lower figure.
- Forbearance treated as zero. The borrower assumes a paused loan does not count. It does.
- Income not documented the way the lender needs. Employment history gaps force extra letters.
- Appraisal short of the target. Value limits the loan amount and the roll-in of costs.
- Occupancy evidence missing. The lender cannot confirm the home is the principal residence.
- Mixing up Streamline and simple. The borrower expects no appraisal and no debt review and learns otherwise late.
Tidy files get fewer questions. Clean documentation does not guarantee approval, but it leaves fewer preventable gaps for the underwriter. Lendmire's piece How to Qualify for an FHA Loan With a High DTI and Student Loans covers the same ratio mechanics on the purchase side.
What Does the Decision Look Like in Practice?
The choice comes down to what you need the loan to do. This table sorts it.
| Your situation | Likely fit |
|---|---|
| FHA loan, DTI is a concern, no change to loan amount | FHA Streamline (non-credit-qualifying), if conditions are met |
| FHA loan, want a fresh full review of the file | Simple refinance, full underwriting |
| FHA loan, want cash out | FHA cash-out, up to 80% LTV on a home owned and occupied 12 months before the case number |
| DTI above what any FHA path supports | Pay down debt, raise income, or compare other programs |
Run the ordering this way. First, decide if a Streamline satisfies the goal. If it does not, check the DTI with the student-loan figure the lender must count. If the number is close, compensating factors and a lower housing payment matter. If it is far off, no document will fix it.
Ways to lower DTI before you apply, roughly from most to least effective:
1. Pay off a small installment loan completely. A cleared account drops its payment from the ratio.
2. Confirm the real student-loan payment. A servicer letter with a lower documented payment may replace a higher credit-report figure.
3. Document all income. Overtime and secondary income count only when the history is documented.
4. Add an eligible co-borrower. Whether a lender will review one on a refinance varies by program and file.

Frequently Asked Questions
Do deferred student loans count toward DTI on an FHA simple refinance?
Yes. HUD requires lenders to include all student loans in the borrower's liabilities regardless of payment status. A deferred or forbearance loan with a zero reported payment triggers a placeholder calculation based on the balance. A servicer letter documenting a real, lower payment can change the figure the lender uses.
Is there one maximum DTI for an FHA simple refinance?
No. The base pair across the wholesale programs Lendmire works with is 31/43, and documented compensating factors can reach 40/50 at the top tier. The automated finding governs most files, and individual lenders may add stricter overlays. A ratio one lender declines can clear elsewhere.
Can I skip the DTI test with a Streamline instead?
Sometimes. The non-credit-qualifying Streamline does not evaluate your debts, per HUD Mortgagee Letter 2021-13. It needs an existing FHA loan, a limited credit review and a net tangible benefit. It also skips the appraisal that a simple refinance requires.
Does a simple refinance need an appraisal?
Yes. The appraisal is what separates it from a Streamline. The appraised value sets the maximum loan, and a shortfall limits how much of the closing costs can be rolled in.
Will a lower housing payment help my ratio?
A lower housing payment can help. If the new payment is lower than the old one, the total ratio can fall even when the student-loan placeholder rises. The new mortgage insurance and term affect the result, so it depends on the file.
