The Quick Read: The best provider depends on your property, credit, and leverage, so compare how each program treats the interest-only period. On the structure Lendmire places, the line is interest-only for 5 years on the drawn balance. The rent test still uses a fully amortizing payment, so interest-only eases your actual cash flow without easing qualification.
- The rental’s rent qualifies the line at a minimum 1.10x on a stress payment across the whole limit. There is no personal income calculation, subject to lender guidelines.
- The structure is a 5-year interest-only draw period, then a 25-year repayment period, for a 30-year maturity at a variable rate.
- At least 80% of the line is drawn at closing, so it behaves more like a funded loan than a standby reserve.
- A second lien reaches 70% combined loan-to-value at a 720 score or better. A first lien reaches 75% loan-to-value at 740 or better, and a first lien above $500,000 is capped at 65% loan-to-value at 720 or better, on lines up to $1,000,000. All of it is subject to underwriting.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the monthly debt payment. A higher number means the rent covers the debt with more room.
HELOC: a home equity line of credit, a revolving line secured by a property you own.
Draw period: the window when you can borrow from the line. Here it is 5 years, and you pay interest only on what you have drawn.
Repayment period: the stretch after the draw period when principal comes due. Here it is 25 years, fully amortizing.
Stress payment: the payment the lender uses to test the rent. It is not the payment you actually make.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Lien position: whether the line sits behind a first mortgage (second lien) or stands first on a property with no mortgage (first lien).
What Is a DSCR HELOC on a Rental?
A DSCR HELOC is a revolving line secured by a non-owner-occupied rental you already own. It is written either as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage. The rent qualifies it. Closing it together with a purchase is not possible, and it is never placed on your own home.
Your personal income is not calculated. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lease, rent schedule, credit report, and valuation are all part of the file. You can hold title in an LLC, depending on program guidelines, and the members sign as guarantors.
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. Lendmire’s complete DSCR loans guide covers the wider family of products this line belongs to.
How Does Underwriting Treat the Interest-Only Period?
Underwriting ignores it for the rent test. Your real draw-period payment is interest-only, but the lender qualifies the property on a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. That is the stress payment. Principal and interest on the full line make it up. Taxes and insurance are not part of it.
The steps run in this order:
1. Collateral check. The rental must be a 1–4 unit, non-owner-occupied property that you already own, with a lease in place. A two-to-four-unit building can have at most 1 vacant unit.
2. Rent figure. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
3. Stress payment. The lender builds the amortizing payment on the whole limit, not on the amount you plan to use.
4. Coverage test. Gross monthly rent divided by that stress payment must reach at least 1.10x.
5. Leverage test. The balance must fit under the CLTV or LTV ceiling for your credit tier.
6. Valuation and title. The property is valued, and title is reviewed.
Because the test uses the full limit, a bigger line raises the stress payment and lowers coverage. Sizing the line is part of passing. On a second lien, confirm on the file how the lender treats the first-mortgage payment, because the lender’s coverage calculation governs.
| Phase | Length | What you pay |
|---|---|---|
| Draw period | 5 years | Interest only on the drawn balance |
| Repayment period | 25 years | Principal and interest, fully amortizing |
| Maturity | 30 years total | Variable rate throughout |
The coverage test runs once, at setup. It does not run again when the draw period ends, but your payment still steps up.
Passing the Ratio Versus Actually Cash Flowing
Passing the ratio and producing cash flow are two different questions. The ratio asks whether rent covers a stress payment. Cash flow asks what is left after your real payment, vacancy, repairs, taxes, insurance, and management.
| Question | In the lender’s ratio | In your real cash flow |
|---|---|---|
| Which payment? | Amortizing stress payment on the full limit | Interest-only on the drawn balance |
| Which rent? | Lesser of market rent and lease (with the receipts exception) | Rent you actually collect |
| Vacancy and repairs? | Not counted | Counted |
| First mortgage? | Treatment set by the lender | Paid in full every month |
The interest-only period helps the right-hand column. Your monthly outlay on the line is lower than an amortizing payment would be. The catch is that the balance does not fall during those 5 years, so you build no equity through paydown on the line.
Think of it as a trade. You get breathing room now and carry the full balance into repayment. That trade makes sense when the borrowed money earns something. A renovation that lifts rent is the clearest case. If the money sits idle, you pay interest on it for nothing.
What Happens When the Draw Period Ends?
Your payment steps up. The repayment period adds principal to every payment, so the bill climbs even if the balance never changed. Experian’s explanation of how a HELOC draw period works makes the same point: repayment payments include principal and run much higher than draw-period payments. Experian also notes that some HELOCs end in a balloon, with the whole balance due at once.
The CFPB’s HELOC booklet describes the same two phases and warns about balloon payments. If you cannot make one, you could lose the property. The program Lendmire places is the amortizing kind, with no balloon. Read the contract on any other product.
Run a modeled example. These are illustrative assumptions, not market data. Say the rent covers the interest-only draw payment at about 1.5x. Suppose repayment lifts the payment by roughly 60%. Coverage on your real payment then falls to about 0.94x. The rent has not changed, but the property now sits below break-even on that line alone.
The first mortgage stacks on top. On a second lien, your total monthly obligation includes both payments. Check coverage across both, not just the line.
The variable rate adds a second moving part. The CFPB’s HELOC brochure says payments may change on a variable-rate plan even when you draw no more money. That is true during the interest-only years too.
Plan the exit before the draw ends. The usual routes are a payoff from sale proceeds, a refinance, or rent growth strong enough to carry principal.
Who Are the Top DSCR HELOC Providers? A Better Question
The better question is which program structure fits your property and your plan. The providers that write this product change with property type, credit, leverage, and location. A broker that shops a network of wholesale DSCR HELOC lenders can match a file to the structure instead of handing you a ranked list. Lendmire is that broker, not a lender, and it does not rank providers.
Here are the criteria that separate one provider from another:
| What to check | Why it matters |
|---|---|
| Length of the interest-only window | Sets how long the lower payment lasts |
| Repayment length | Longer repayment keeps the stepped-up payment smaller |
| Test payment basis | Whether the rent test runs on the full limit or only on the amount drawn |
| Draw-at-close requirement | Decides how much cash you must take on day one |
| Minimum later draw | Limits how flexibly you can redraw |
| Lien positions offered | Second lien, first lien, or both |
| Entity vesting | Whether your LLC can stay on title |
| Rate adjustment | Variable, or convertible to fixed |
| Fees and prepayment terms | Come with the lender’s disclosures and change the real cost |
Programs differ on every row, and some sell a closed-end second as a HELOC. Those products pay out one fixed amount and do not revolve. Ask whether you can draw, repay, and redraw.
Lendmire’s piece on investment property HELOC options with an interest-only period covers the version qualified on personal income instead of rent. The structure here is the rent-qualified one.
What Leverage and Line Sizes Are Available?
Leverage depends on lien position and credit score. These are ceilings through select programs, subject to underwriting, not offers.
- Second lien on an investment rental: up to 70% CLTV at a 720 score or better, on lines from $50,000 up to $500,000. Below 720, no second-lien tier exists.
- First lien on an investment rental with no mortgage: up to 75% LTV at 740 or better, and up to 70% LTV from 700 to 739, on lines up to $500,000.
- First lien above $500,000: 65% LTV at 720 or better, on lines up to $1,000,000. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
A borrower who keeps a first mortgage can only take a second lien, and that tier starts at 720. A first lien exists only on a rental with no mortgage. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Draws work like this. At least 80% of the line is drawn at closing, and the closing draw is never under $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws are at least $5,000 each.
That heavy opening draw matters for cash flow. You pay interest on most of the line from day one. Size the line to a specific use of money, such as a renovation or a down payment on another rental. The purchase lender decides whether line proceeds count toward the down payment, closing costs, or reserves.
What Does the File Look Like?
The file is lean on income and firm on the property.
Valuation. Lines up to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
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).
Credit. The floor is 720 on a second lien and 700 on a first lien, using the lender’s own report. Programs look for no 30-day mortgage late in the last 12 months. They also want 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
Reserves and exposure. There are no reserve or cash-to-close requirements. A borrower can carry at most 5 loans or $2,500,000 with the program.
Property. Eligible types are single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums. Lots to 10 acres can qualify. Excluded types include:
- rural-designated property
- row homes
- condotels
- mixed-use, commercial, and agricultural property
- leaseholds
- land trusts
- age-restricted communities
- a property listed for sale in the prior 2 months
- a property with a solar lien
Borrowers. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers are not eligible.
Footprint. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Where the General Rule Breaks
A few edge cases change how you read the interest-only label.
Closed-end interest-only loans compute coverage differently. On some interest-only closed-end DSCR loans, the lender computes coverage on interest, taxes, insurance, and dues rather than full principal and interest. That can raise the ratio. A DSCR HELOC with a fully amortizing stress payment on the whole limit does not work this way, so the interest-only draw payment does not help the rent test. Always ask which payment the lender uses.
You cannot buy with it. The line needs an already-owned rental. It cannot close together with a purchase of the same property. First-time investors usually start with a purchase loan.
Assets do not rescue weak rent. A large bank balance cannot make up for a property whose rent fails the test.
The rate floats through both periods. On the network Lendmire works with, it never converts to fixed. Some outside lenders offer fixed-rate conversions, so check before you assume.
Above-market leases need proof. A lease above market counts only with three months of receipts.
Balloon plans exist elsewhere. Check any contract for a balloon clause before comparing it to this structure.
A home loan is a different product. A primary-residence HELOC is owner-occupied, and this line is never offered on an owner-occupied home.
HELOC, Closed-End Second, or Cash-Out Refinance?
The structure of the money differs, and so does the best fit.
| Factor | DSCR HELOC | Closed-end second | DSCR cash-out refinance |
|---|---|---|---|
| Money arrives | Mostly at closing, then redraws | One lump sum | One lump sum |
| First mortgage | Stays in place | Stays in place | Replaced |
| Payment during interest-only years | Interest only on drawn balance | Set by the product | Set by the product |
| Best suited to | Staged use of equity | A single fixed need | Larger amounts and portfolios |
A cash-out refinance replaces your first mortgage, which is a poor trade if you hold a mortgage you like. A line leaves it alone. A cash-out suits larger amounts, entity-held property, and portfolios.
When Should You Skip It?
Skip this line in these situations:
- The rent only just clears 1.10x on the stress payment, and you have no plan for the step-up.
- You want a standby reserve, not funded cash. The 80% opening draw works against that.
- You want to buy the property that would secure it.
- Your property type or location is on the excluded list.
- You hold the rental in a way the program does not accept, such as a land trust.
An investor with heavy personal debt can still use this structure, because personal income is not calculated. That is an advantage only if the property itself carries the payment.
Frequently Asked Questions
Does the interest-only period lower the payment used to qualify?
No. Qualification runs on a fully amortizing stress payment on the entire credit limit. The interest-only payment is your actual bill during the draw period. It improves cash flow, not the rent test.
Can I draw only what I need?
Not at closing. After that, later draws must be at least $5,000 each. Match the line to a specific use of money.
How long must I own a rental before I can open a line?
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).
Is the rate fixed or variable?
Variable. Payments can change even if you draw nothing more, and that applies in both the draw period and repayment. Rates and pricing terms come with the lender’s disclosures.
Which provider is best for my rental?
That depends on the property type, credit profile, leverage you need, and where the rental sits. A broker that shops multiple wholesale lenders can match the file to a program. Qualification is subject to lender guidelines, credit approval, and property review.
