Do Student Loans and a HELOC Payment Both Count in Your DTI?

The Quick Read: It depends on the loan. On a personal-income loan, yes: a student loan payment and a HELOC payment both count in your debt-to-income ratio. On a DSCR loan, neither enters the qualifying ratio, because the property’s rent is tested against its own payment, though both still show up in your credit review.

• Personal-income loans add every recurring monthly debt to your housing payment, then divide by gross monthly income.
• DSCR loans compare rent to the property’s full monthly obligation (PITIA). Your student loan is not in that math.
• A HELOC is itself a personal-income product. On an investment property, the network’s line caps at 70% CLTV and is reviewed against a 50% maximum DTI.
• Credit, reserves, and later applications still feel both debts, even when the DSCR ratio does not.

Which Loan Counts Which Debt?

The answer flips by loan type, so start with the comparison.

Many investors assume “no DTI” means the debt vanishes. It doesn’t. It is absent from one test, and a later lender running a DTI test may count it again.

How a DTI Lender Counts a Student Loan

A DTI lender counts the student loan payment as a recurring monthly obligation, whether the loan is federal or private. The tradeline appears on your credit report, and the underwriter assigns it a monthly figure.

Standard repayment is easy: the reported payment goes into the total. Deferred, forbearance, and income-driven loans are the judgment calls. Many borrowers assume a deferred loan counts as zero, and under DTI rules it often does not.

Freddie Mac’s selling guide sets out its own student loan treatment, including a threshold of 10 or fewer remaining payments. That is one agency’s rule and a contrast point only. It does not govern DSCR files, and other DTI lenders set their own methods.

Here is the practical takeaway. If your loan is in deferment, ask any DTI lender what payment figure it will use before you assume the debt is invisible.

How a HELOC Payment Counts

A HELOC counts because it creates a monthly payment, and the payment lenders use is usually conservative. On the HELOC program we broker, the qualifying payment is the interest-only amount calculated on the maximum draw, not on whatever balance you carry. At least 75% of the line is drawn at closing, so the payment is real from day one.

Lenders vary. Some use the drawn balance, and some assume a fully drawn line. If you are comparing lenders, ask which method each uses.

The network’s HELOC parameters work like this:

• DTI: a 50% maximum. It is 45% for credit profiles from 600 to 679, and a ratio above 45% requires a 680 minimum.
• Investment property lines: 70% CLTV at 700+ credit, up to $500,000, on a 5-year interest-only draw followed by a 25-year repayment.
• Primary residence lines: the ceiling reaches 90% CLTV, but only at 720+ credit and up to $500,000. Lower credit tiers carry lower ceilings.
• Title: an LLC cannot hold title on these lines. The borrower or a revocable living trust must.

These are typical ranges from select wholesale lenders, subject to lender guidelines and full file review. Lendmire’s piece Use HELOC for Investment Property Will Affect DTI goes deeper on that mechanic.

What the Combined Number Looks Like

Picture one borrower in three steps. Start with a mortgage payment and no other debts. DTI sits at a comfortable level.

Add the student loan. DTI rises by the loan’s share of gross income. Add the HELOC’s interest-only payment on the full line, and it rises again, often by more than the student loan did. The HELOC step is usually the larger jump, because the payment is sized to the maximum draw.

If the total passes a lender’s cap, the usual levers are:

1. Paying down or paying off the student loan before application.

2. Taking a smaller HELOC line, which lowers the qualifying payment.

3. Adding a co-borrower with income, if the program allows it.

4. Paying off a debt at or before closing, so it drops out of the calculation.

That last point reflects how personal-income lenders treat debts that are paid off at or before closing: those debts are not included in the debt-to-income calculation. Lenders in that setting also count a simultaneous loan on the same property, such as a HELOC opened alongside a new first loan, as its own factor. This framing shapes how personal-income lenders think about a borrower’s obligations.

Why DSCR Skips Both Debts

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 file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio is rent divided by PITIA: principal, interest, taxes, insurance, and any HOA dues. Your student loan and HELOC are not in either number.

Know the benchmarks. A 1.00 ratio is where select programs start, not a universal standard. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Eligibility rests on the lender’s guidelines, your credit, and the property.

For purchases, most files land at 75%–80% LTV. Select programs reach 85% LTV with roughly a 700+ score. Cash-out refinances top out around 75% LTV. The complete DSCR loans guide walks through the full program range.

One caution deserves its own line. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities, and capex all sit outside the calculation.

Where Your Personal Debts Still Show Up

DSCR files are not blind to you. Four places stay open:

• Credit score. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage. A late student loan payment or a collection can sink a file here, even though the balance itself is not in the ratio.
• Reserves. These vary by lender, leverage, and loan size. Around 6 months of PITIA is common, and larger loans typically step up to about 9 months. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived.
• Later DTI lenders. A DSCR loan may appear on your credit report or carry a personal guaranty. A future personal-income lender may count it.
• Your real cushion. A HELOC drawn against the same rental, or against your home to fund a down payment, never enters the DSCR ratio. Its payment still comes out of the rent, so actual cash flow shrinks.

An investor who funds a down payment with a HELOC should treat the line as a second obligation on the rental’s income.

Which Path Fits Which Investor?

For a W-2 borrower with one rental and low debts, a personal-income loan may carry a lower cost and fewer moving parts. For that borrower, the student loan is a minor line, and DSCR’s extra pricing may not pay off.

The flip point comes when personal debts crowd the ratio. Heavy student loans plus a HELOC can push a strong earner past a DTI cap. Self-employed investors, LLC-held portfolios, and borrowers adding the fourth or fifth financed property often hit the same wall. There, DSCR moves from alternative to only practical lane.

Consider the HELOC itself as a decision. If you plan to refinance into a DTI-based loan within a few years, a drawn line uses up the room you will need. If the next deal is DSCR, the line costs you cash flow but not qualification. Tax treatment can depend on how the funds are used and how the property is held. Investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

DSCR is not available on manufactured homes (single- and double-wide), log homes, or barndominiums. Those property types are not offered in the network.

Key Terms Defined

• DTI (debt-to-income): Your total monthly debt payments, including the new housing payment, divided by gross monthly income.
• DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly obligation.
• PITIA: Principal, interest, taxes, insurance, and any HOA dues on the property.
• CLTV (combined loan-to-value): All loans secured by the property, added together, as a share of its value.
• HELOC: A revolving home equity line with a draw period and a repayment period.

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Reach the team at 828-256-2183 or through the quote request page. Whichever route you take, run both tests before you commit: enough personal-income room for any DTI-based loan, and enough rental coverage for a DSCR file.
