The Quick Read: A DSCR HELOC is a revolving credit line secured by a duplex, triplex or fourplex you already own, and it qualifies primarily on the rent the building produces rather than on your personal income, subject to lender guidelines. It sits as a standalone second lien behind the first mortgage you keep, or as a first lien on a rental with no mortgage, and the owner’s LLC can stay on title.
- Lien position: a standalone second lien behind your existing first mortgage, or a standalone first lien on a paid-off rental.
- Coverage test: gross rent must reach at least 1.10x a stress payment calculated on the entire credit limit.
- Leverage: second liens reach 70% combined loan-to-value at a 720 score or better; first liens reach 75% LTV at 740 or better, through select programs.
- Terms: a 5-year interest-only draw period, then 25 years of repayment, with a variable rate.
- Footprint: offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Most investors who ask about this product have the same goal. They own a 2-4 unit building, the first mortgage is working, and they want the equity without refinancing the loan they have. This guide walks through how the structure works, how underwriting treats it step by step, where it breaks, and how to decide. For the full picture of the loan family, see Lendmire’s complete DSCR loans guide.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is an open-end line of credit secured by a non-owner-occupied rental, qualified on the property’s income. A standard HELOC is a revolving line: you borrow up to a limit, repay, and borrow again. The federal consumer-finance regulator’s HELOC explainer describes it as an open-end line that lets you borrow repeatedly against the equity in a property.
The DSCR part changes who is being underwritten. A bank HELOC leans on your income and debt load. This one leans on the building. Gross monthly rent is divided by a qualifying payment, and that ratio is the debt service coverage ratio. The program reviews the file on the rental’s income: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
“DSCR HELOC” is a market label, not a single standard product. Across the wholesale network, the same words can describe four different things:
| Product | What it is | Reviewed on |
|---|---|---|
| DSCR HELOC | Revolving line on your rental | Rent coverage |
| Investment-property HELOC at a bank | Revolving line on your rental | Personal income and DTI |
| DSCR cash-out refinance | New first mortgage replacing the old one | Rent coverage |
| Primary-residence HELOC | Line on the home you live in | Personal income |
Ask which one is actually being offered before you spend time on any file. A line on your own home is a different, owner-occupied product, and this line is never written on an owner-occupied property or a second home.
Why Are Rental HELOCs Hard to Find?
Rental HELOCs are scarce because many lenders treat rentals as higher risk than owner-occupied homes. NerdWallet notes that not every lender offers a HELOC on an investment property and that the requirements run stricter. It also points to a DSCR second mortgage as an option for a primarily rented property.
That matches what a broker sees. Large retail lenders often decline the request outright or push you toward an owner-occupied product. Investors who stretch the truth about occupancy to get one are taking a real risk with the loan. A rental is a rental. The better path is a lender whose program was built for rental collateral from the start.
How Does Underwriting Treat a 2-4 Unit Building, Step by Step?
Underwriting runs in a fixed order, and each step can end the file. Here is the sequence on most programs in the network.
Step 1: Eligibility screen. The property must be a non-owner-occupied one-to-four-unit rental you already own. A two-to-four-unit building may have at most one vacant unit. Title can be you, or your LLC, subject to program eligibility; LLC members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
Step 2: Seasoning. 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).
Step 3: Lien position. With a mortgage in place, the line is a standalone second lien behind it. Your first mortgage stays untouched. With no mortgage, the line is a standalone first lien. It is never closed together with a purchase and never sits as a third lien.
Step 4: Rent. The rent counted is the lesser of the appraiser’s market rent (from a Form 1007 rent schedule) or the lease. A lease above market can count when three months of receipts support it. A lease in place is required, and rent is summed across the units.
Step 5: Coverage test. Gross monthly rent is divided by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit, calculated at the start rate plus 2 percentage points. It is a stress payment, so a half-drawn line is tested as if fully drawn. The minimum is 1.10x. Whether the first-mortgage payment joins that calculation on a second lien is set by the lender’s own coverage method, and the lender’s calculation governs.
Step 6: Credit. A 720 score is the minimum on a second lien and 700 on a first lien, using the lender’s own report. There should be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Step 7: Combined leverage and valuation. The first mortgage balance plus the full line, divided by value, must fit the CLTV cap. Value comes from an automated valuation with a property inspection report on lines up to $400,000, or from a full interior appraisal. Larger lines take a full appraisal. Appraisal waivers are not accepted.
Step 8: Documents. Expect leases, the first-mortgage statement, insurance, entity documents where relevant and business-purpose disclosures. The rent, the lease, the credit report and the valuation are all documented. Only the personal income file is skipped.
Most files that fail do so at steps 1, 4 or 7. Unit count and title come first. Then rent against a stress payment, and last the equity left after the first mortgage.
What Leverage and Line Sizes Are Available?
Leverage depends on lien position and credit tier, and these figures are ceilings, not offers, subject to underwriting and select programs.
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien | 740 or better | 70% CLTV | $50,000 to $500,000 |
| Second lien | 720 to 739 | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000, to $1,000,000 |
Below 720 there is no second-lien option. A market the lender flags as declining lowers the ceiling by 5 points, and some metros carry a lower ceiling still. Hazard insurance must cover both liens, with flood coverage where required.
The key arithmetic is that CLTV counts the full line, not what you draw. A rental bought with 20-25% down usually has little room left under a 70% combined cap once the first mortgage is counted. Equity is the limiting factor far more often than rent. Older, well-paid-down buildings are the natural candidates.
How Do the Draw Period and Repayment Work?
The line has a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
That first-draw rule is the biggest difference from a bank line, where you can open a limit and draw nothing. Here, most of the line is borrowed on day one. Treat it as a mostly funded second loan with a small revolving tail. If you only want a standby reserve, this structure may not fit.
The end of the draw period matters more than most investors plan for. The CFPB warns that payments are often significantly higher once repayment begins, and its HELOC brochure adds that monthly payments on a variable plan can change even if you draw nothing more. Test the building against the amortizing payment, not just the interest-only one. A building that passes at 1.10x on the stress payment has a thin cushion for a variable rate.
How Does Unit Count Change the Risk?
Unit count changes how much one vacancy hurts, and the program allows at most one vacant unit in a 2-4 unit building. That cap hits a duplex harder than a fourplex.
Picture a duplex with one unit empty. Half the rent is gone, and the coverage ratio falls with it. A fourplex with one empty unit loses a quarter of its rent and keeps most of its cushion. Both can pass the vacancy rule, but only one is likely to still clear 1.10x.
Run a quick test before you apply. Take the lesser of lease or market rent for each occupied unit, add them, and compare the total to the stress payment on the full line. Then repeat with your weakest unit set to zero. If the building only works with every unit leased, the file has little margin for a bad month. The lender’s own calculation governs the final number.
One boundary matters a great deal here. If you live in one unit, the building is owner-occupied, not a non-owner-occupied rental, and this program does not apply. That house-hacking case belongs to owner-occupied programs.
Second Lien or First Lien: Which Fits Your Situation?
The right structure depends on whether you have a mortgage worth keeping. The table below sorts the common cases.
| Your situation | Likely fit |
|---|---|
| Low-cost first mortgage you want to keep | Second-lien line |
| Rental owned free and clear | First-lien line |
| Thin equity after a recent purchase | Likely wait, or consider other options |
| Need a single lump sum and a new first loan | DSCR cash-out refinance |
| Rental titled in your LLC | Eligible, subject to program terms |
The main reason to choose a line is to leave the first mortgage alone. A cash-out refinance replaces that loan, along with its terms. If the first mortgage is a good one, a second lien protects it. If the existing loan is expensive anyway, a refinance may be cleaner. The first mortgage’s own documents may also limit a junior lien, so confirm that early.
Where Does the General Rule Break?
Several edge cases catch investors who assume the product works like a bank line.
- Thin equity. Rent can be strong and the file still fails, because the first mortgage plus the full line exceeds the CLTV cap.
- Property types. Rural-designated property, row homes, condotels, mixed-use and commercial or agricultural property are outside this lane. So are leaseholds, land trusts, age-restricted communities, modular and log homes, and land contracts.
- Recent listing. A property listed for sale in the prior 2 months is out. So is a property with a solar lien.
- Borrower status. Foreign nationals and ITIN borrowers are not eligible. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are.
- Portfolio size. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
- State. The program is not offered everywhere. It runs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
- Variable rate. Because the rate floats, a file that barely clears the ratio can look different a few years into repayment.
Passing the coverage test does not mean the building cash-flows once the line is drawn. The test uses a stress payment. Your actual numbers also include maintenance, vacancy and capital repairs.
What Do Lenders in the Network Actually Look For?
Across the wholesale network, lenders look at four things in this order: the property type, the rent against the stress payment, the equity left under the cap, and the credit tier. Reserves and cash to close are not required on this program. That makes the equity position and the lease file the real gates.
Tradeline-depth rules are waived at 700 and above, and every tier the program offers meets that score. So the credit conversation is mostly about the score itself and the 12-month mortgage history. Expect a lender to want clean title and a clear first-mortgage statement before anything else.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment; this program’s minimum is 1.10x.
HELOC: a revolving credit line secured by property equity that you can draw on, repay and draw again within program rules.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by property value.
Lien position: the order in which lenders are repaid if the property is sold or foreclosed; a second lien is repaid after the first.
Stress payment: the fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to test coverage.
Form 1007: the appraiser’s rent schedule that sets market rent for a rental property.
Seasoning: the time you must have owned, or held a loan on, the property before it is eligible.
Is a DSCR HELOC the Right Move for You?
It fits an investor who owns a 2-4 unit building with real equity, a first mortgage worth keeping, and rent that clears 1.10x on the stress payment. It also suits self-employed owners and those with large portfolios whose personal income file is hard to underwrite.
It is a poor fit if you want a standby line you rarely touch, since most of the line is drawn at closing. It is also a poor fit if the building only works when every unit is leased, or if you plan to occupy one unit. In those cases a cash-out refinance, a bank statement product or waiting for more equity may serve better.
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. 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.
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals.

Frequently Asked Questions
Can I get a DSCR HELOC if my rental is in an LLC?
Yes, an LLC can hold title, and vesting in the owner’s 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. Eligibility remains subject to program terms and underwriting.
Does the coverage test use the amount I draw or the full line?
The full line. The qualifying payment is a fully amortizing stress payment on the entire credit limit, so a partly drawn line is tested as if it were fully used. Combined leverage also counts the whole limit, not just the drawn balance.
What happens if one unit is vacant?
A two-to-four-unit property may have at most one vacant unit, and rent counts only for leased units on the lesser-of-lease-or-market basis. A vacancy lowers the coverage ratio, so a duplex has far less margin than a fourplex.
Can I draw only a little at closing?
No. At least 80% of the line, and never less than $50,000, is drawn at closing, and later draws are at least $5,000 each. If you want a mostly undrawn standby line, ask about other structures.
