The Quick Read: A home equity line payment counts against your rental income in two different ways, depending on the loan you apply for next. A personal-income loan treats the payment as a debt against your earnings. A property-income loan usually leaves it out of the coverage ratio unless the line sits on the same property. The cash still leaves your account every month either way.
- On a personal-income loan, the line payment is a debt, and rent is usually counted at a discount.
- On a DSCR loan, only the subject property’s own payment is tested, so a line on a different property usually stays outside the ratio.
- A line sitting behind a DSCR first mortgage on the same property adds to the debt side, and coverage can fall below 1.00x.
- Clearing 1.00x is not the same as positive cash flow, because repairs, vacancy, and management sit outside the ratio.
- On the investment-property lines Lendmire places, the ceiling is 70% CLTV up to $500,000, and an LLC cannot hold title.
What “Rental Income” Means here
Here, rental income means the rent a lender counts to qualify you for a loan. It does not mean rent as defined for tax purposes. 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.
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.
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.
Key Terms Defined
HELOC (home equity line of credit): A revolving credit line secured by property, with a draw period when you borrow and a repayment period afterward.
DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly debt payment. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the full monthly payment on the property.
DTI (debt-to-income ratio): Your monthly debts divided by your monthly personal income.
CLTV (combined loan-to-value): All loans secured by the property, added together, divided by its value.
Subordination: A junior lender’s written consent to stay behind a new first mortgage. It is not automatic.
Where Does the HELOC Payment Land?
The payment lands in one of three places: on the debt side of your personal ratio, inside the property’s coverage ratio, or outside the test entirely. Which one applies depends on the loan you are applying for and where the line is secured.
| Situation | How the payment is treated |
|---|---|
| Personal-income loan (DTI test) | Counted as a monthly debt |
| DSCR purchase, line on a different property | Usually outside the ratio |
| Line behind a DSCR first on the same property | Added to the combined payment |
| HELOC draw used as the down payment | Lender decides if borrowed funds are acceptable |
The first row is the one most landlords have in mind. The second row surprises people. DSCR measures the deal, not the borrower, so a line secured by your primary home does not enter the property’s ratio. It still comes out of the same rent in your real budget.
How the Payment Counts Against Rental Income on a Personal-Income Loan
Personal-income underwriting nets rent against the property’s payment. Any shortfall becomes a debt. According to a Fannie Mae-based rental income explainer, lease-based rent is typically counted at 75% of gross rent, and rental losses add to the borrower’s debt obligations. The Fannie Mae Selling Guide is the rule source for that conventional treatment. It does not govern DSCR files.
Run the numbers this way, using modeled ratios and not market data. Say gross rent covers the property’s payment 1.10 times. At 75%, counted rent covers it only about 0.83 times. The gap becomes a monthly debt on your personal ledger. Your new line payment is then stacked on top as a separate debt.
That is why a thin-looking rental can sink a personal-income application even when the rent is real. The tax-return version of your rental income is often smaller than the lease suggests. Lenders working from traditional personal-income documentation see the net figure, not the lease.
Sequence matters here. If you want personal-income financing, apply for it before you open the line. If you plan to go the DSCR route, the line’s DTI impact matters less. Lenders still review your credit, and the line shows on your credit report.
How Lenders Calculate the Line Payment for Qualification
Lenders do not always test the payment you plan to make. On the investment lines Lendmire places, qualification runs on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. A DTI up to 50% is the typical ceiling on these files, subject to lender guidelines.
A line has two phases. The CFPB’s HELOC brochure explains that the draw period comes first, and payment terms vary by plan. Some plans require principal plus interest. Others allow interest-only payments during the draw. Interest-only is common, not universal.
On an investment property, the line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats across both periods and never converts to fixed. So an undrawn line is not much of a feature on these files, because most of the money is out the door on day one.
The step-up at repayment is the main risk to your cash flow. Opendoor’s explainer describes the jump from interest-only to amortizing payments as significant, and larger if rates have risen. Plan for that step before you draw.
Some retail lenders count an unused line at its full limit in your DTI, as one BiggerPockets thread describes. That is one anecdote, so confirm how the specific lender treats it.
When the HELOC Sits Behind a DSCR First Mortgage
This is the one case where the payment does count in the ratio. Qualification runs on rent covering the combined payments of both loans on that property.
Picture a rental whose first mortgage is covered about 1.25x by rent alone. Add a second-lien payment that raises total debt service by roughly 30%. Coverage drops to about 0.96x, below 1.00x, even though nothing about the tenant or the rent changed.
Many select DSCR programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Neither path is the standard. Stronger coverage opens better pricing and leverage.
The two approvals can also fail independently. The line is approved on your credit, DTI, equity, and title. The DSCR loan is approved on rent against PITIA, leverage, and reserves. Passing one does not carry the other.
Using HELOC Money as a Down Payment on a DSCR Purchase
The DSCR lender decides whether borrowed money counts as acceptable funds. Many programs in the network accept a documented line draw. Others want a minimum from unborrowed funds. Ask before you draw.
The paper trail runs from the line statement showing the draw, to the transfer into your account, to the final settlement statement. Because DSCR loans are business-purpose, they are exempt from TRID (Reg Z 1026.3), so the consumer closing disclosure does not apply. Most files land at 75% to 80% LTV on a purchase, with select programs reaching 85% LTV at roughly a 700 score or better. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
A bigger down payment lowers the monthly payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. Reserves vary by lender, leverage, and loan size, and commonly run around six months of PITIA.
The strongest files clear two tests: enough equity and enough rental coverage.
Where the Line Rules Break the General Pattern
LLC title. Lines on the network require title held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. DSCR loans to LLC-titled borrowers are available subject to program terms. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead.
A line already on title. A later DSCR cash-out creates a new first lien. Any second lien must be paid off or subordinated. Not every junior lender consents. Read your line’s documents before you plan the refinance.
An existing DSCR first mortgage and a new line. The first mortgage’s documents may limit additional liens. Read them before you apply.
Availability. Many large retail lenders do not write lines on non-owner-occupied property. Benzinga’s investor guide lists foreclosure risk and negative cash flow among the main downsides of these lines. Lendmire’s line placements cover fewer states than its DSCR footprint of 41 markets, including Washington, D.C.
Credit and size. An investment-property line needs a 700 score, a hard floor with no tier beneath it. The ceiling is 70% CLTV up to $500,000 at both 700 and 720, so a higher score above 700 buys eligibility, not leverage. On a primary residence, the ceiling reaches 90% CLTV only at a 720 or better credit profile.
Valuation. Because an investment line caps at $500,000, it runs in the automated-valuation lane and commonly closes without a traditional appraisal.
Portfolio limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
Property types. Manufactured homes, log homes, and barndominiums are not offered on these lines or on the network’s DSCR programs. Condotels and co-ops are not offered either.
Short-term rentals. DSCR files on short-term rentals use their own leverage tiers and documentation of income. See Lendmire’s explanation of what a lender counts as short-term rental income. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Self-employed landlords. Bank-statement income can support a line on documented income under the applicable program, subject to lender guidelines. Business accounts need a 680 minimum for deposit analysis. On an investment line the 700 floor is the binding constraint anyway.
What Clearing the Ratio Does Not Tell You
DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex all sit outside the calculation. A property can clear 1.00x and still lose money after those costs. It can lose more once a line payment is added.
A line-funded down payment puts a second monthly obligation against the same rent. The risk is a rental that stalls while the line payment is still due. Many investors plan a later cash-out refinance to retire the line balance, which makes the line a bridge with an exit. Cash-out refinances typically top out around 75% LTV on standard rentals, with about six months of seasoning as the common expectation. For more on that strategy, see Lendmire’s piece Why Landlords Are Tapping Record Equity With a Rental HELOC.

Common Misconceptions
The line payment counts against my DSCR. Usually not, when the line is on a different property. It does count when the line is a second lien on the same property.
So it is free money against my ratio. No. It is a real cash outflow, and the line shows on your credit report.
A line qualifies me on the rental’s income. No. The line is sized on you, not on the rent. A full fourplex and a half-vacant one with the same value and balance produce the same ceiling.
Every line is interest-only. Not always, as the CFPB brochure above notes.
Any DSCR lender accepts line money as a down payment. Treatment varies by program.
What to Do If the Numbers Fail
If the line pushes coverage under 1.00x, you have a few levers. Draw less, which lowers the payment. Put more down. Pay the line down before applying. Or ask about a select-lender path that accepts coverage below 1.00, with leverage and terms adjusted. Qualification stays subject to lender guidelines, credit approval, and property review.
Frequently Asked Questions
Does a HELOC payment lower my rental income on a DSCR loan?
Usually not, because the ratio only compares that property’s rent to its own PITIA. A line secured by a different property sits outside it. If the line sits behind a DSCR first mortgage on the same property, the combined payments are tested against the rent.
Does the HELOC count against my DTI?
Yes, on any loan that tests personal income. The payment is added to your monthly debts. On the investment lines Lendmire places, the payment is qualified on the interest-only amount on the maximum draw.
Can I use a HELOC draw as my down payment on a rental?
Often, but the purchase lender decides. Some DSCR programs accept a documented draw, and others require a minimum from unborrowed funds. Document the draw, the transfer, and the closing statement.
Can my LLC hold a HELOC?
No. Title must be held by you personally or by a revocable living trust. A rental already in an LLC typically needs a vesting change or a DSCR cash-out refinance, depending on program terms.
What is the maximum line on an investment property?
Investment lines cap at $500,000 and 70% CLTV, with a 700 minimum score. A line above $500,000 is available only on primary residences, with a full appraisal. Every figure is subject to lender guidelines and full file review.
