The Quick Read: Lenders count your monthly student loan payment, not your balance, inside your debt-to-income ratio, so the useful question is whose method, cutoff, and property rules fit your file, not who ignores the debt. Across the wholesale network Lendmire works with, HELOC programs cap debt-to-income at 50%, with tighter limits at lower credit scores.
- The monthly payment counts. The balance does not.
- Each lender picks its own way to figure the payment on deferred or income-driven loans.
- Network lines qualify on the interest-only payment calculated on the maximum draw, so the full line size matters.
- Investment-property lines top out at 70% CLTV and require a 700 minimum credit profile. Primary-residence and second-home lines reach 90% CLTV only with a 720 or better credit profile.
- A DSCR loan tests rent against the property’s payment instead of your personal debt ratio. It is a different product with its own credit, reserve, and equity rules.
Key Terms Defined
Debt-to-income ratio (DTI): your total monthly debt payments divided by your gross monthly income.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
HELOC: a home equity line of credit, a revolving line secured by a property you already own.
Interest-only draw period: the first stretch of the line, when the required payment covers interest only. After it ends, the balance amortizes.
Income-driven repayment (IDR): a federal student loan plan that sets your payment as a share of your income. The payment can be low or even zero.
Deferment and forbearance: approved pauses on student loan payments. The loan stays on your credit report.
DSCR (debt service coverage ratio): monthly rent divided by the property’s monthly payment, including principal, interest, taxes, insurance, and any HOA dues.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
What Kinds of Banks Offer a HELOC When Student Loan Debt Counts Against Income?
Lenders that underwrite a HELOC on DTI generally count student loans in some form, so expect them to show up in the math wherever you apply. The difference between lenders is the method for assigning a payment, the DTI ceiling, and the property types they accept. That is why this article names no banks. Large retail lenders, regional depositories, and wholesale-funded programs all run their own policies, and a lender that suits a salaried homeowner with one loan may not suit a borrower with a deferred balance and a second property.
Lendmire is a mortgage broker, not a lender. It arranges home equity lines through select wholesale partners, and those lenders review and approve each file. Because it sees several sets of guidelines side by side, the broker’s job is matching your scenario to the program whose rules fit. That means property use, credit profile, how much equity you want to reach, and how your income and debts look on paper.
The best program for your situation depends on those inputs. No ranked list of lenders can answer it, because the same file can be a clean fit at one program and a decline at another.
How Underwriting Counts Student Loans, Step by Step
Underwriting turns each student loan into one monthly number, adds the new line’s payment, and divides the total by your gross monthly income. The flow is the same almost everywhere. Only the numbers inside it change.
1. Credit pull. Each student loan shows up as an installment account with a balance, a status, and a reported monthly payment. Federal and private loans both appear. NerdWallet lists student loan payments among the debts that go into DTI.
2. Payment assigned. If the loan is in repayment, the lender generally uses the reported payment or the servicer’s statement. If the report shows no usable payment, the lender estimates one. Where that estimate comes from varies by lender and program.
3. New line added. The HELOC’s own payment joins the pile. Network programs review your file on the interest-only payment calculated on the maximum draw. That means the whole line counts, not just what you plan to use.
4. DTI computed. Every monthly debt, including the new line, divided by gross monthly income.
5. Cutoff applied. In the network, 50% is the maximum DTI. For credit profiles from 600 to 679 the ceiling is 45%, and any ratio above 45% requires a 680 minimum.
6. Other gates. Credit score, CLTV, property type, occupancy, and valuation all run alongside DTI. A strong ratio does not rescue a file that fails them.
Spouses are a common question. A spouse’s student loans count only when the spouse is on the note. Debts that are in your spouse’s name alone sit outside your file.
How Each Student Loan Situation Is Typically Counted
The table shows the common treatments. Individual lenders set their own methods for counting student loan payments, so confirm the method before you apply.
| Situation | How it is typically counted | What to have ready |
|---|---|---|
| Standard repayment | Reported monthly payment | Recent servicer statement |
| Deferment or forbearance | Often an estimated payment, not $0 | Deferment letter, loan balance |
| Income-driven plan | Varies; a documented $0 is not accepted everywhere | Plan approval letter |
| Co-signed loan | Counts for the co-signer | Credit report, payment history |
| Parent PLUS | Counts for the parent on the note | Servicer statement |
| Paid off | Drops out of DTI | Payoff letter |
A Two-Pass DTI Example
Run the numbers on a modeled borrower. These are assumptions, not market data.
Pass one. Existing monthly debts equal 40% of gross monthly income. Student loans make up 12 points of that. The new line, qualified on the interest-only payment at the maximum draw, adds 9 points. Total DTI is 49%.
That is under the 50% maximum, but above 45%. The file now needs a 680 or better credit profile. A borrower at 665 hits a wall.
Pass two. Now the borrower pays off a car loan that carried 5 points and requests a smaller line that adds 5 points rather than 9. Existing debts fall to 35%, the new payment adds 5, and DTI lands at 40%. That clears both the 45% and the 50% thresholds.
Nothing about the student loans changed. Shrinking the line and clearing one other debt moved the ratio more than any argument about the loans could.
What the Network’s HELOC Programs Actually Allow
HELOC ceilings depend on how you use the property, so no single figure applies. The wholesale partners offer a standalone line in first or second lien position. Lines run $25,000 to $750,000, with the largest sizes reserved for primary residences.
| Property use | Max CLTV | Credit floor | Max line |
|---|---|---|---|
| Investment property | 70% | 700 | $500,000 |
| Second home | 90% (720+ only) | 640 | $500,000 |
| Primary residence | 90% (720+ only) | 600 | $500,000 at 90% CLTV (720+); $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
On a primary residence, the leverage steps down with credit. A 700 profile reaches 85% CLTV up to $500,000, and lower tiers sit below that. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the 5-year-draw program described below) and a full appraisal.
Two draw structures exist. One program runs a 3-year interest-only draw followed by a 17-year repayment. The other, called here the 5-year-draw program, runs a 5-year draw followed by a 25-year repayment. Investment lines use the 5-year structure only. At least 75% of the line is drawn at closing on both, and pricing floats rather than converting to fixed. Figures apply only within their own program’s terms, and all of them are subject to lender guidelines and full file review.
Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal, though a higher CLTV can trigger a secondary valuation. You can always request a full appraisal.
Availability is narrower than the broker’s investor footprint. These lines are offered in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
Where the General Rule Breaks
Student loans count everywhere, but several situations change how.
Income-driven plans with a low or zero payment. Treatment is inconsistent. A documented zero-payment status is accepted by some programs and rejected by others, and there is no HELOC-wide standard. Ask the lender how it treats your plan before you apply. The details of income-driven plans change over time, so check the current terms with your servicer.
Co-signed and parent loans. If your name is on the note, the payment lands in your file, even when someone else makes it.
Title and vesting. The line must be held by you as an individual or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history splits by program. The 3-year-draw program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4 on primary residences and second homes. The 5-year-draw program declines that history on those properties regardless of age.
Property type. Single-family, 2-4 unit, PUD, townhome, and condo (including non-warrantable) properties are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not offered.
Exposure. A borrower can hold three lines at most, and owning more than 15 financed properties makes you ineligible. Investors who stack lines run into that quickly.
Why No Federal Formula Settles This
No federal rule tells a HELOC lender how to count a student loan. The federal ability-to-repay rule covers consumer mortgages but carves out home equity lines. Each lender therefore picks its own payment method and its own cutoff.
The CFPB defines DTI as your monthly debt payments divided by your gross monthly income. It also notes that limits differ by loan product and lender. That is why two banks can look at the same file and give opposite answers.
When Your Plan Is a Rental, Not a Home
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal DTI, and the student loans inside it, is not the test. Credit, reserves, and property review still apply.
Clearing a coverage ratio of 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation. Stronger ratios open better terms and higher leverage. Select programs begin at 1.00, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
Typical network ranges, subject to lender guidelines:
- Purchase: most files land at 75%-80% LTV, with select high-leverage programs reaching 85% for roughly a 700+ score.
- Cash-out refinance: tops out around 75% LTV, with about 6 months of seasoning commonly expected.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest tiers.
- Reserves: commonly around 6 months of PITIA, varying by lender, leverage, loan size, and transaction type.
- Entity: LLC vesting is available, depending on program guidelines.
The complete DSCR loans guide walks through those numbers. One caution: a DSCR loan relaxes personal income documentation, not credit review.
Ways to Lower DTI Before You Apply
Move the ratio before you ask for the line. These steps work on any DTI-based file.
- Pay off a small installment loan. Removing a payment helps more than shaving a large balance.
- Request a smaller line. The payment is calculated on the maximum draw, so a smaller line cuts the number directly.
- Fix the student loan payment on paper. If your servicer can document a lower, valid payment under a plan you qualify for, the file reflects it.
- Hold credit above a key threshold. Reaching 680 matters because it lifts the DTI ceiling above 45%.
- Add a qualifying co-borrower. Their income counts. Their debts do too.

Should You Pay Off Student Loans With a HELOC?
Not automatically. Swapping student debt for a secured line trades unsecured debt for a lien on your property. Federal loans carry protections such as income-driven plans and deferment options. Once you pay them off with a HELOC, those protections are gone.
Interest-only draws also keep the balance from shrinking during the draw period. The line then amortizes, and the payment steps up. Run the payment you would face after the draw ends, not just the one you start with.
Document Checklist
- Recent servicer statements for each student loan
- Deferment, forbearance, or income-driven plan letters
- Proof of income for every borrower on the note
- Mortgage statement on the property
- Trust documents, if the property sits in a revocable living trust
- Homeowners insurance declarations
Frequently Asked Questions
Do student loans count against me if they are deferred?
Often, yes. A deferred loan stays on your credit report, and many lenders assign an estimated payment instead of $0. The method differs by lender, so ask before you apply.
Do federal and private student loans count the same way?
Both appear on your credit report and both feed into DTI. Federal loans may offer income-driven payments that lower the monthly figure, which some lenders accept and others question.
What DTI do network HELOC programs allow?
The maximum is 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% requires a 680 minimum. Each figure is subject to lender guidelines and full file review.
Can I get a HELOC on a rental property with student loans?
Yes, on an investment property the network allows up to 70% CLTV with a 700 minimum credit profile and a $500,000 maximum line, subject to lender guidelines. Your student loan payment still counts in DTI, and the title must be in your name or a revocable living trust.
Is a DSCR loan a better route if my student loans are heavy?
It can be. A DSCR loan is reviewed primarily on property rent covering the payment, so personal DTI is not the test. You still need credit, reserves, and an eligible property, and a DSCR cash-out refinance is a separate product from a HELOC.
