The Quick Read: A DSCR HELOC does not buy the property. It is a revolving line secured by a rental you own, qualified primarily on that rent, subject to lender guidelines, rather than on your personal income. It supplies the down payment cash while a separate purchase loan finances the rest. Every file runs on two loans, two lenders and two properties.
- The line sits on a rental you already own, as a standalone second lien behind your first mortgage or a standalone first lien on a paid-off rental.
- Through select programs, the rent must cover a stress payment on the entire line at a minimum 1.10x, subject to underwriting.
- Combined leverage on a second lien tops out at 70% CLTV, so the equity cushion decides the size of the line.
- The line must close and fund before the purchase closes, and the purchase lender decides whether borrowed funds are acceptable.
- The new rental has to carry both its own loan and the line payment in real cash flow.
What Is a DSCR HELOC?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied one-to-four-unit rental, qualified on the property’s rent. Investors usually call it a DSCR HELOC because the debt service coverage ratio, rent against the payment, is the test the line must pass.
The label confuses people. A bank HELOC on a rental tests you: income, credit and debt-to-income. A rent-qualified line tests the property. Across the wholesale network, the product described here is written only on a rental, never on your own home or a second 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.
Trade press describes the underlying idea in plain terms. Scotsman Guide notes that an investor can qualify on the cash flow the properties generate, with that cash flow expected to cover the mortgage, taxes and insurance. That article is dated, so use it for the concept only. Program specifics change, and each file is underwritten individually.
This page covers the revolving line. A closed-end second lien and a cash-out refinance are different tools, compared further down.
How Do the Two Loans Fit Together?
The line and the purchase loan are separate files. Each has its own lender, its own collateral and its own decision.
| Factor | DSCR HELOC | Purchase loan on the new rental |
|---|---|---|
| Collateral | Rental you already own | Rental you are buying |
| What it provides | Cash for down payment and costs | The bulk of the purchase price |
| What the lender tests | Rent vs. stress payment on the full line | New property’s rent vs. its own payment |
| Lien position | Second lien or first lien | First lien |
| Decision | Does your existing rental support the line? | Does the new rental support the loan? |
Picture an investor who owns a rental with a first mortgage. The investor opens a line on it, draws cash, and puts that cash toward the next purchase. If the new rental underperforms, both properties are exposed. That two-property exposure is the real cost of the structure.
Step by Step: From Equity Check to Repayment
The sequence matters, because the line cannot be closed together with the purchase. You cannot borrow against a property you have not bought yet.
1. Measure the equity. Equity is value minus the first mortgage balance. For a second lien, the first mortgage plus the new line, divided by value, is the combined loan-to-value (CLTV). That figure must stay at or under the program ceiling.
2. Confirm the rental is eligible. It needs a lease in place and has to be a property type the lane accepts. Some properties are excluded outright, covered below.
3. Qualify the line on the rent. The lender compares gross monthly rent to a stress payment on the whole credit limit. Rent is the lesser of the appraiser’s Form 1007 market rent or the lease. A lease above market counts only with three months of receipts.
4. Order the valuation. Lines up to $400,000 use an automated valuation plus a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
5. Close the line and take the first draw. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
6. Put the contract in place and confirm the funds with the purchase lender. Do this before you draw. Sourcing rules differ by program.
7. Close the purchase. The purchase lender sees your down payment as borrowed money and reviews the new rental on its own rent and payment.
8. Plan the exit. The 5-year interest-only draw period ends and a 25-year repayment period begins, inside a 30-year maturity. Payments step up when repayment starts.
The program also uses a seasoning rule. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date). A brand-new landlord has no seasoned rental to borrow against. That is why this route is for investors who already hold property.
How Does Underwriting Treat the Line?
Underwriting treats it as a rent test on a stress payment. The test uses a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. Gross monthly rent divided by that payment must reach at least 1.10x, through select programs and subject to underwriting.
Two details trip files. First, the test runs on the full limit, not the drawn balance. A large limit with a small draw is still tested as if fully used. Second, the 80% minimum draw at closing means you pay on most of the line from day one. Size the line to what you need, not to the maximum.
On a second lien, the lender’s own coverage calculation governs whether the first-mortgage payment joins the qualifying payment. Programs differ here, so do not assume either answer. Ask for the calculation before you plan around it.
This is a residential investor convention. Commercial real estate defines the ratio as net operating income over debt service, and Wikipedia’s debt service coverage ratio entry gives that formula and notes a 1.25 commercial minimum. That 1.25 is not the residential DSCR convention. Select residential programs, including this one, set their own floors.
The line is reviewed on the rental’s income: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines. The file is still documented. The lease, the credit report and the valuation are all in it.
Leverage, Credit and Line Size
Leverage depends on lien position. All figures below are ceilings, not offers, through select programs and subject to underwriting.
| Position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien, rental | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien, rental with no mortgage | 740 or better | 75% LTV | Up to $500,000 |
| First lien, rental with no mortgage | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, line above $500,000 | 720 or better | 65% LTV | To $1,000,000 |
Below 720 there is no second-lien option. The first-lien floor is 700. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
Credit history matters too. The program looks for no 30-day mortgage late in the last 12 months. It also wants 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu. At 700 and above, tradeline-depth rules are waived. No reserves and no cash to close are required, subject to underwriting. Exposure per borrower is capped at 5 loans or $2,500,000 with the program.
Run the percentages on a rental. Say the first mortgage is 45% of value. Under a 70% CLTV ceiling, the new line could take up to 25% of value, before any declining-market adjustment. The calculation shows why a recent purchase with a high-leverage first mortgage leaves little room.
Where the General Rule Breaks
Most of the friction sits in these edge cases.
- Entity title. Vesting in your LLC is allowed on investment property. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Keep entity documents clean and current. Whether an LLC is accepted depends on program guidelines.
- The first mortgage’s terms. The first mortgage stays in place, so its documents must permit a second lien. Read them before you apply.
- Ineligible property. Rural-designated property, row homes, condotels, commercial or agricultural property and leaseholds are out. So are land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use. A property listed for sale in the prior 2 months and a property with a solar lien are also out. Condominiums, warrantable and non-warrantable, are eligible property types, but the leverage tiers above govern.
- Vacancy in small multifamily. A two-to-four-unit property may have at most 1 vacant unit.
- Borrower status. US citizens, permanent residents and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers cannot.
- Hazard coverage. Hazard insurance must cover both liens, plus flood coverage where required.
- Primary-residence lines. A HELOC on your own home is a different, owner-occupied product, and this line is never offered on an owner-occupied home. The CFPB’s HELOC explainer is written from the consumer side and notes that HELOCs usually carry variable rates and that payments can jump when repayment begins. It does not address rent-based qualifying on a rental. It still shows the payment-step risk this line shares.
Will the Purchase Lender Accept Borrowed Funds?
It depends on the purchase program, so ask before you draw. Treat the down payment, closing costs and reserves as three separate questions. Some programs accept line proceeds for the down payment but want other cash behind reserves. Others restrict borrowed money more tightly.
Ask the purchase lender three things before you close the line:
- Can borrowed line funds count as the down payment?
- What documentation shows the draw and where it landed?
- Does the lender add the line payment to its own coverage test?
The line payment is usually not in that ratio, but this varies by program. Passing the purchase test is also not the same as cash flowing. The line payment comes out of your pocket if the new rent falls short.
A Worked Comparison in Ratios
Run a three-way comparison on the same purchase, with all coverage figures purely illustrative. The lender’s own calculation governs.
| Scenario | New rental coverage on its own loan | Cash flow after the line payment |
|---|---|---|
| Cash down, no line | Around 1.2x | Positive |
| Line-funded down payment | Around 1.2x | Thin to negative |
| Line-funded plus a vacancy stress | Below 1.0x | Negative |
The purchase loan shows the same coverage whether the down payment came from cash or the line. The difference appears in your real cash flow, because the line payment now sits on top. A vacancy on the new property, or a payment step-up at the end of the 5-year interest-only draw period, can turn a thin position negative. This is why many investors keep the line as short-term bridge capital.
Line, Cash-Out Refinance, Closed-End Second or Cash?
The right tool depends on your first mortgage. A line keeps it, a cash-out refinance replaces it, and cash leaves the rental untouched.
| Option | First mortgage | Payment shape | Best fit |
|---|---|---|---|
| DSCR HELOC | Stays in place | Variable rate, interest-only draw | Keep a favorable first mortgage, draw as needed |
| DSCR cash-out refinance | Replaced | New term loan | First mortgage is not worth keeping |
| Closed-end second lien | Stays in place | Fixed lump sum | One-time need, known amount |
| Cash down | Untouched | None | Enough savings, no added debt |
Choose the line when your first mortgage is worth keeping and you want a flexible draw. Choose a cash-out refinance when the first mortgage has no advantage worth protecting.
Risks, and Who Should Skip This
Skip the structure if you have no seasoned rental, if your equity cushion is thin, or if your cash flow cannot carry both payments. The risks are specific.
- Two-property exposure. Default on either loan can put the other property in play.
- Payment step-up. The rate is variable, and payments rise when the 25-year repayment period starts.
- Full borrowed down payment. Financing the whole down payment leaves no equity cushion in the new rental and drags cash flow.
- Early refinance penalties. If you plan to refinance the purchase loan early, check whether it carries a prepayment penalty first.
- Exit risk. The standard exit is a refinance of the new rental after it stabilizes, with the line paid down from the proceeds. That depends on the property performing and on lender guidelines at the time.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment, with this program’s floor at 1.10x on a stress payment.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Second lien: A loan recorded behind the first mortgage, which stays in place.
Draw period: In this program, 5 years of interest-only payments on the drawn balance, followed by a 25-year fully amortizing repayment period.
Stress payment: A fully amortizing payment on the whole credit limit at the start rate plus 2 percentage points, used only to test coverage.
Seasoning: The time a rental must be held or financed before it can carry the line.
Where This Fits in the Bigger Picture
The line is one piece of a DSCR investing plan. The purchase loan, the property-level rent test and the exit all follow the same logic of qualifying on the property. Lendmire’s complete DSCR loans guide lays out how those pieces connect.
Lendmire is a broker. It arranges these lines through a wholesale lender in its network. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Frequently Asked Questions
Can a DSCR HELOC pay for the whole property?
No. The line supplies cash, usually for the down payment and closing costs. A separate purchase loan finances the rest, and the purchase lender may limit how much borrowed money it accepts.
Does the line payment count against the new property’s DSCR?
On most files the purchase lender tests the new property’s rent against that property’s own payment. Policies vary, so confirm with the purchase lender before you close the line. Your real cash flow still has to pay both loans.
Can a first-time investor use this?
No. The line needs a seasoned rental with equity, a lease in place and rent that the lender can review. A first-time investor without one needs another source for the down payment.
Can the line be written in my LLC?
Yes, on investment property, subject to program guidelines.
Is the interest deductible?
It can depend on how the funds are used and how the property is held. Tax treatment varies; consult a qualified professional.
