The Quick Read: A DSCR HELOC is a revolving line of credit on a rental you already own, qualified on that rental’s income instead of your personal income. It produces cash for your next purchase, but it does not buy the property; a separate purchase loan does that. Subject to lender guidelines, the line can sit as a second lien behind your existing mortgage or as a first lien on a paid-off rental.
- The line goes on a rental you already own, never on the one you are about to buy.
- Rent must cover a stress payment on the whole line at a minimum of 1.10x.
- Second-lien leverage tops out at 70% combined loan-to-value, subject to underwriting.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
- At least 80% of the line is drawn at closing, so it behaves more like a loan than a standby reserve.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a market label, not a standardized product. In Lendmire’s wholesale network it means a home equity line of credit on a non-owner-occupied one-to-four-unit rental, sized on the rent and the equity in the property. Tax returns, W-2s, pay stubs, and a personal debt-to-income ratio never enter the calculation. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
The “HELOC” half of the name describes the structure. A home equity line is open-end credit: you borrow against equity, repay, and in many plans borrow again, as the CFPB’s HELOC explainer describes. A draw period comes first, then a repayment period, and payments often rise sharply when repayment begins.
The “DSCR” half describes the test. Debt service coverage ratio is gross monthly rent divided by the qualifying payment. On one-to-four-unit rentals the brokerage uses gross rent, not the net operating income method common in commercial lending. Lendmire’s complete DSCR loans guide covers the ratio in more depth.
One caution on naming. Three different products get called a DSCR HELOC online, and they are not interchangeable:
| Feature | Rent-qualified line | Income-qualified rental HELOC | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Rental’s rent | Borrower’s income and debts | Rental’s rent |
| First mortgage | Stays in place | Stays in place | Replaced |
| LLC title | Allowed on this program | Often barred | Program-dependent |
| Structure | Revolving line | Revolving line | Closed-end loan |

How Does Underwriting Treat It, Step by Step?
Underwriting runs in a fixed order, and the order explains most of the surprises investors hit.
1. Lien position. The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never a third lien and never closes together with a purchase.
2. Value. Lines to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
3. Rent. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease must be in place, and a two-to-four-unit property may have at most one vacant unit. Market rent comes from the appraiser’s Form 1007 for a one-unit property or Form 1025 for two to four units.
4. The coverage test. Rent divided by the qualifying payment must reach at least 1.10x. That payment is principal and interest, fully amortizing, on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, not what you will actually pay during the draw period. Taxes and insurance are not part of it.
5. Combined leverage. On a second lien, the first-mortgage balance plus the new line, divided by value, can reach 70% CLTV at a 720 credit score or better, on lines up to $500,000.
6. Credit, title, and property review. No personal income calculation does not mean no underwriting. The lender pulls credit, reviews title, and checks the property type. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Here is the part the brokerage sees investors miss. The test runs on the full limit, not the drawn balance. A $300,000 line with only part drawn is still stress-tested as if it were fully amortizing on the whole $300,000. Whether the first-mortgage payment joins the qualifying payment on a second lien depends on the lender’s coverage calculation, so confirm on the file how the lender treats it.
What Does the Line Actually Look Like Once You Have It?
The terms are rigid compared with a bank line on your own home. Expect a variable rate (the rate and pricing terms come with the lender’s disclosures), a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, for a 30-year maturity. Interest-only payments during the draw are a common feature of these lines, as Bankrate’s interest-only HELOC overview explains.
Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000, so on the smallest lines the whole line is drawn up front. Later draws are at least $5,000 each. That is why calling it a standby reserve misleads. You pay interest on most of it from day one.
| Term | Program figure |
|---|---|
| Line size | From $50,000 |
| Closing draw | At least 80% of the line |
| Later draws | At least $5,000 each |
| Draw period | 5 years, interest-only |
| Repayment | 25 years, fully amortizing |
| Maturity | 30 years, variable rate |
All figures are subject to underwriting and select program guidelines.
How Much Can You Borrow Against the Rental?
Leverage depends on lien position and credit tier, and the two positions use different measures. Second liens use CLTV; first liens use LTV.
| Lien position | Credit score | Maximum | Line size |
|---|---|---|---|
| Second lien (CLTV) | 720 or better | 70% | Up to $500,000 |
| First lien, no mortgage (LTV) | 740 or better | 75% | Up to $500,000 |
| First lien, no mortgage (LTV) | 700 to 739 | 70% | Up to $500,000 |
| First lien, no mortgage (LTV) | 720 or better | 65% | Above $500,000 to $1,000,000 |
A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower. These are ceilings, not offers.
Consider an owner with a rental worth $500,000 and a first mortgage of $250,000. At 70% CLTV, the combined balance can reach $350,000, so the new line could be sized against roughly $100,000 of that room, assuming a 720 score and a rent that clears 1.10x on the full line. If rent only covers the stress payment at about 1.0x, the file fails the coverage test no matter how much equity exists. Rent, not equity, is often the binding constraint.
A first lien exists only on a rental with no mortgage. A borrower who keeps a first mortgage can take only a second lien, with its 720 floor.
Which Rental Carries the Line?
The rental you already own carries it. The property you are buying cannot, because the line is never closed together with a purchase. A cash offer is therefore usually two steps: the line on an owned rental funds the offer, and a later DSCR cash-out refinance on the new property can repay the line.
Two seasoning clocks apply. 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). That timing matters for first-time landlords: buy the rental first, let it season, then open the line later. An investor with no existing rental has nothing to borrow against.
Each rental is tested on its own rent and its own debt. Equity does not pool across properties, so a portfolio of five rentals means up to five separate lines, each underwritten individually. The program caps exposure at 5 loans or $2,500,000 per borrower.
How Does the Cash Fund the Next Purchase?
The loop runs in a set order:
1. Open the line on an owned, seasoned rental.
2. Receive the closing draw (at least 80% of the line).
3. Use the cash for the next purchase’s down payment, closing costs, or rehab.
4. Finance the purchase itself with a separate loan, such as a DSCR purchase loan.
5. Let the new rental season, then repeat if the numbers support it.
The new purchase is judged on its own rent and its own loan. Lenders generally treat the line’s payment as outside the new loan’s ratio, though that is a lender-guideline point and worth confirming on your file. Separate underwriting ratios do not change your real cash flow, though. Your actual monthly carry is the new mortgage plus the line’s payment, and the line’s interest-only payment becomes a much larger amortizing payment after year five, as the CFPB’s explainer warns about repayment-period payment shock.
The stronger play usually treats the line as short-term capital. Investors who recycle through a quick rehab and a cash-out refinance on the new property can retire the line within the draw period. Investors who plan a long hold on the borrowed money are carrying a variable-rate balance against thin early cash flow, and that is where deals break. A BiggerPockets Rookie episode makes the same point: the new rental has to cover its own expenses and mortgage plus the HELOC payment.
Where Does the General Rule Break?
Edge cases are where most files get rejected, so they deserve their own list.
- Short-term rentals. The appraiser’s rent form is built on monthly-lease comparables and was not designed to estimate nightly rates, per Fannie Mae’s Appraiser Update. A nightly-rate rental does not map cleanly onto lease-based rent.
- Condos. Warrantable and non-warrantable condominiums are eligible property types, but two gates apply: the rent test and the building review. Condotels are excluded.
- Excluded property. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use, a property listed for sale in the prior 2 months, and a property with a solar lien are all outside this lane.
- LLC title. Vesting in the owner’s LLC is allowed on this program (investment property only). The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. Many bank HELOCs on rentals bar LLC title, as investors on BiggerPockets describe.
- Rehab-driven value. An automated valuation will not capture value you have not yet built. Larger lines require a full interior appraisal anyway.
- Borrower status. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
- Your own home. This line is never offered on an owner-occupied home or second home. A primary-residence HELOC is a different product.
Line, Cash-Out Refinance, or Purchase Loan Alone?
The decision turns on what you want to keep. Honestly, it is close to a toss-up in many files.
| Your situation | Likely better fit | Why |
|---|---|---|
| Existing first mortgage you want to keep | DSCR HELOC | First mortgage stays untouched |
| Paid-off rental, one-time capital need | Cash-out refinance | Closed-end structure, no variable balance |
| Plan to recycle through BRRRR | DSCR HELOC | Short-term capital, repay at the exit refinance |
| Rent barely clears 1.0x | Neither, re-examine the deal | Line needs 1.10x on the full limit |
| Long hold, thin cash flow | Purchase loan with cash savings | Variable balance can compound risk |
The flip point is the existing mortgage. If your first mortgage is attractive and you want to leave it alone, a second-lien line is the only way to reach equity without touching it. If you would be refinancing anyway, a DSCR cash-out refinance may be cleaner.
The line is wrong when the equity is real but the rent is weak, when you cannot absorb the post-draw payment step-up, or when you have no seasoned rental to borrow against. In those cases, the right move is usually a different deal, not a different loan. 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.

Frequently Asked Questions
Can I use the line on the rental I’m buying?
No. The line is secured by a rental you already own, and it is never closed together with a purchase. The new property is financed separately, often with a DSCR purchase loan, while the line supplies down-payment or rehab cash.
Does the line count against my ratio on the next purchase?
Generally the line’s payment sits outside the new loan’s coverage ratio, because each rental is tested on its own rent and debt. That is a lender-guideline point, so confirm it on your file. Your real cash flow still carries both payments.
How long must I own the rental first?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date).
Can an LLC hold title?
Yes, subject to program terms. The LLC’s members sign as guarantors, and the line is for investment property only. Many bank rental HELOCs do not allow this.
What happens when the draw period ends?
Borrowing stops and the balance amortizes over 25 years, so the payment steps up from interest-only. Plan the exit, whether a refinance or a payoff from a sale, before you draw.
