The Quick Read: A DSCR HELOC is a revolving line of credit on a rental, and the 70% combined loan-to-value cap counts the first mortgage you keep plus the whole new line against the property’s value. Whatever room is left under that cap is the most the line can be, subject to underwriting. The rental’s rent, not your personal income, qualifies the line, subject to lender guidelines.
- A DSCR HELOC (home equity line of credit) sits as a standalone second lien behind your first mortgage, or as a first lien on a rental with no mortgage.
- Second liens reach 70% combined loan-to-value at a 720 credit score or better, on lines from $50,000 to $500,000.
- Rent must cover a stress payment on the entire line at a minimum of 1.10x.
- The draw period is 5 years interest-only, then 25 years of repayment, with a variable rate.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Say you own a rental with a good first mortgage you don’t want to touch. You want cash for the next deal, and you don’t want to hand over tax returns again. That is the investor this product was built for. The rest of this guide shows the arithmetic, the two tests a file has to pass, and the places the rule breaks. For the bigger picture, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
DSCR (debt service coverage ratio): the property’s gross monthly rent divided by the qualifying payment. A result of 1.10x means the rent is 110% of that payment.
HELOC: a home equity line of credit, which is revolving credit secured by property. You borrow, repay, and borrow again within the rules.
LTV (loan-to-value): one loan balance divided by the property’s value.
CLTV (combined loan-to-value): all loans secured by the property, including the new line, divided by value. Freddie Mac’s credit risk transfer glossary defines it as the total unpaid balance of all known outstanding loans at origination compared with the property’s value.
Lien position: your place in line to be repaid. A first lien is paid first. A second lien is paid after the first mortgage.
Draw period: the stretch when you can take money from the line and pay interest only on what you used.
What Is a DSCR HELOC, Exactly?
It is a revolving line on a non-owner-occupied one-to-four-unit rental. The “DSCR” part describes how the line is qualified. The label is informal, not a standardized product, and some lenders underwrite an investment-property line on personal credit and debt-to-income instead. The two paths are different. A DSCR HELOC qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. You provide no traditional personal-income documentation, W-2s, or personal income calculation.
The structure is simple. The line is a standalone second lien behind the first mortgage you keep. Or it is a standalone first lien on a rental with no mortgage. It is never closed with a purchase, never a third lien, and never placed on your own home or a second home. Your LLC can hold title, subject to program terms. The members sign as guarantors, and anyone on title who is not a borrower signs an acknowledgment.
The federal consumer regulator describes a HELOC as an open-end line you can borrow against repeatedly, up to the limit, during the draw period, per the federal consumer-finance regulator’s HELOC explainer. It also counts as a second mortgage if you already have a first. Investment-property versions are a niche. NerdWallet notes the lender pool is smaller and the requirements are strict. Across Lendmire’s wholesale network, that matches what files look like.
How Does the 70% Combined Cap Work?
The cap works as one subtraction. Multiply the property’s value by 70%, then subtract everything already secured by the property. What remains is the room for the line, up to the program’s dollar limit.
The formula in one line: maximum line = (value × 70%) − first mortgage balance, capped at $500,000.
Run it in percentages of value. Take a rental worth 100 units of value, with a first mortgage at 50% of value. The cap allows 70, the first mortgage uses 50, so the line can reach 20% of value. Not 70%. The most common mistake is reading “70%” as the size of the line. It is the ceiling on all debt together.
Here is how room changes as the first mortgage grows, at a 70% cap:
| First mortgage, % of value | Room for the line | What it means |
|---|---|---|
| 0% (paid off) | Up to 70% | Eligible as a first lien, at 70% or more by tier |
| 30% | 40% of value | Plenty of room |
| 50% | 20% of value | Moderate room |
| 65% | 5% of value | Likely under the $50,000 minimum line |
| 70% or more | None | No second lien possible |
That last row matters. A recent high-leverage purchase often leaves zero room. And even with no mortgage at all, 30% of value stays out of reach on a second lien at this cap.
The $50,000 minimum line also bites. Room may exist on paper but fall below the smallest line the program writes. Values are illustrative, and the lender’s own calculation governs.
Why Does the Whole Line Count, Not Just the Drawn Balance?
Most investors expect to count only what they borrow. Programs differ on this, and many measure combined loan-to-value against the full credit limit. Plan as if the full limit counts, then confirm on your file. That is why sizing the line a bit under the cap can be wise: you pay nothing extra for a cap you never use, and a smaller line leaves cushion if the valuation lands low.
The same logic shapes the rent test. The qualifying payment is figured on the entire limit, not the amount you drew.
What Is the Second Test: Rent Coverage?
The equity test asks how much you can borrow. The rent test asks whether the rental can carry it. Both must pass.
The minimum coverage is 1.10x. Gross monthly rent is divided by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit, figured at the start rate plus 2 percentage points. It is a stress payment, built to be heavier than what you will actually owe during the interest-only draw period. Taxes and insurance are not part of the qualifying payment.
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 in place is required. A two-to-four-unit property may have at most one vacant unit. 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.
Whether the first-mortgage payment joins the qualifying payment on a second lien is something to confirm on the file. The lender’s coverage calculation governs.
Which test binds first? In practice, the equity test usually limits a second lien on a leveraged rental, and the rent test limits a big line on a modest rent. Picture a rental with a small first mortgage and strong rent. The cap leaves room, and rent clears 1.10x easily. Now picture one with a small mortgage but thin rent. Room exists, but the stress payment on the full line outruns the rent, so the line shrinks. Run both before assuming a number.
What Credit and Leverage Tiers Apply?
Here is the leverage grid, all subject to underwriting and through select programs:
| Lien | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien | 720 or better | 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 tier. A borrower with a first mortgage who sits at 700 to 719 cannot take a second lien, and a first lien exists only on a rental with no mortgage. A higher score above the floor often buys eligibility, not extra leverage, at the second-lien tier.
Other credit rules apply. There can be no 30-day mortgage late in the last 12 months. Forty-eight months must pass since a bankruptcy, foreclosure, short sale, or deed in lieu. No reserves and no cash to close are required. Each borrower is limited to 5 loans or $2,500,000 with the program.
Some conditions lower the ceiling. A declining-market flag takes 5 points off, and Philadelphia lines carry a ceiling 10 points lower.
How Is the Property Valued?
Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report. A full interior appraisal is also accepted. Larger lines require the full interior appraisal. Appraisal waivers are not accepted.
Value is the denominator of the whole calculation, so it moves the line. A lower valuation shrinks the cap in dollars. A line sized right at the cap can end up trimmed. This is another reason to size slightly under.
How Does the Line Behave After Closing?
At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws are at least $5,000 each.
The draw period is 5 years, interest-only on the drawn balance. Then comes a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable.
Plan for payment movement. Variable-rate payments may change, and plans secured by a dwelling must carry a ceiling on how high the rate can rise. Payment also steps up when repayment begins and principal joins the bill. Treat the rate and pricing terms as coming with the lender’s HELOC disclosures. The CFPB’s HELOC page also warns that a lender might stop further draws if the property’s value drops significantly. Do not count on a line as your only reserve.
Which Properties and Borrowers Are Outside the Program?
Eligible: single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. Borrowers can be U.S. citizens, permanent residents, and non-permanent residents with a Social Security number.
Not eligible on this lane: 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 two months, and a property with a solar lien. Foreign nationals and ITIN borrowers are not eligible.
What Does Seasoning Require?
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). Both clocks are checked at the file level, subject to underwriting.
Where Does the General Rule Break?
These are the edge cases that surprise people:
- An existing DSCR first mortgage. Check the first lender’s documents for limits on junior liens. A rental that clears coverage comfortably on its first mortgage alone feels tighter once a second line is added.
- A recent high-leverage first. If the first mortgage is already near 70% of value, no second lien fits. You may need to wait for paydown or for values to rise.
- A tiny remaining room. Under the program’s minimum line size, the line does not exist, even though the formula shows a positive number.
- A mismatch in who signs. Borrowers on the line need not be the borrowers on the first mortgage. Title holders who are not borrowers still sign an acknowledgment and the security instrument.
- The same equity, a different product. If the room under 70% is thin, a DSCR cash-out refinance may reach more, but it replaces the first mortgage. Lendmire’s page on DSCR HELOC vs. DSCR cash-out refinance at 70% combined loan-to-value walks through that tradeoff.
DSCR HELOC, Bank HELOC, or Cash-Out Refinance?
| Factor | DSCR HELOC | Bank HELOC on a rental | DSCR cash-out refinance |
|---|---|---|---|
| Qualified on | Rent | Typically personal income and DTI | Rent |
| First mortgage | Stays in place | Stays in place | Replaced |
| LLC title | Allowed, subject to program terms | Often individual or trust only | Often allowed |
| Funds | Revolving | Revolving | One lump sum |
| Lender pool | Small | Small | Wider |
Bank figures and rules in that column describe those lenders’ own programs, not this one. Many HELOC programs lend only to individuals or revocable trusts, which is the usual reason an LLC owner is steered to a cash-out refinance.
A short decision path helps:
1. Do you want to keep a good first mortgage? Then a line fits better than a refinance. 2. Is there at least $50,000 of room under 70%? If not, wait, pay down, or consider a refinance. 3. Does rent clear 1.10x on the stress payment for the whole line? If not, shrink the line. 4. Do you need staged money, such as rehab draws or the next down payment? A line suits that. Remember it creates a second loan and gives you no equity in the new property.
What Happens If You Refinance the First Mortgage Later?
A second lien sits behind the first. If you later refinance the first mortgage, the new first lender will want to stay ahead of your line. That usually means the line’s lender must agree to stay behind the new loan, or you pay the line off. Plan for that before you pick a first-lien product, and ask at that point how the new lender treats the line.
Frequently Asked Questions
Is a DSCR HELOC a second mortgage?
Yes, when you keep a first mortgage. It is a standalone second lien behind that loan. On a rental with no mortgage, it is a first lien instead.
How is the maximum line calculated at 70% combined?
Value times 70%, minus the first mortgage balance, capped at $500,000 on a second lien. Count the full line against the cap, not only the drawn amount. The lender’s calculation governs.
Can my LLC hold title?
Yes, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument. Investment property only.
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).
Does it use my tax returns?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still reviews credit, the lease, and the valuation.
