The Quick Read: A DSCR HELOC lets a landlord keep the existing first mortgage untouched and add a standalone second lien behind it, qualified on the rental’s income instead of the owner’s personal income. Through select programs, the line is sized by combined leverage, a minimum coverage ratio, a credit tier and a valuation, all subject to underwriting. The low first mortgage is the asset, because it leaves more room under the combined cap.
- Second lien: up to 70% combined loan-to-value (CLTV) at a 720 score or better, on lines of $50,000 to $500,000.
- Coverage: a minimum 1.10x, tested on a stress payment sized on the entire credit limit.
- No traditional personal-income documentation, W-2s, pay stubs or debt-to-income calculation. The LLC can stay on title, subject to lender guidelines.
- A lease must be in place. The rental must clear two six-month seasoning clocks: it cannot have been bought or refinanced within the last 6 months, and the owner must have held title for at least 6 months.
- Offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What Is a DSCR HELOC on a Rental Property?
A DSCR HELOC is a revolving line of credit secured by a non-owner-occupied rental of one to four units. The property’s rent qualifies it. The owner’s paycheck, tax returns and personal debt-to-income ratio are not part of the calculation.
The line is written in one of two positions. It is a second lien behind a first mortgage the owner keeps. Or it is a first lien on a rental that has no mortgage at all. It is never closed together with a purchase, never a third lien, and never a line on the owner’s own home.
The label gets used loosely, so ask which product is on the table. Three different things get sold under similar names:
| Product | What qualifies the file | What happens to the first mortgage |
|---|---|---|
| DSCR HELOC (second lien) | Rent covering a stress payment | Stays in place |
| DSCR cash-out refinance | Rent covering the new payment | Paid off and replaced |
| Personal-income rental HELOC | The borrower’s income and debts | Stays in place |
NerdWallet’s guide to HELOCs on investment property notes that not every lender offers a line on a rental, that requirements run stricter than on a primary home, and that more than one appraisal may be required. That supply gap is why rent-qualified lines exist in the wholesale channel.
Across the wholesale network, the rent-qualified structure is the one that fits investors who hold several mortgaged rentals, hold title in an LLC, or would rather not open the personal income file. The complete DSCR loans guide covers the broader program family.
Why Lien Position Decides Everything When You Keep a Low First
Lien position follows recording order. A mortgage already recorded on the property is the first lien. Any new line recorded after it sits behind it as a second lien. A new line cannot jump ahead of a mortgage you plan to keep.
That is the whole logic of the strategy. The old first loan keeps its balance, its rate and its term. The new line is a separate loan with its own terms. Nothing about the first mortgage is refinanced.
Two practical consequences follow.
First, the lender counts both loans when it measures leverage. A second lien is sized on combined loan-to-value: the first mortgage balance plus the new line, divided by value. A smaller first balance leaves more room.
Second, a second lien carries a higher credit floor than a first lien. On a second lien the minimum score is 720. On a first lien it is 700. A borrower at 700 to 719 who keeps a mortgage therefore cannot use the second-lien lane, whatever the equity looks like.
One more check sits outside the program. Read the first mortgage’s note and security instrument for due-on-sale and junior-lien language before applying. Ask a real estate attorney if the wording is unclear. The line does not change the first loan’s terms, but the first loan’s documents still govern what the owner may record behind it.
The Requirements, Gate by Gate
Every file runs through the same gates: borrower, property, credit, rent coverage, leverage, valuation, title and seasoning. All figures below are ceilings and floors, subject to underwriting, and none is an offer.
| Gate | Requirement through select programs |
|---|---|
| Borrower | Citizen, permanent resident, or non-permanent resident with SSN |
| Occupancy | Non-owner-occupied rental, 1–4 units |
| Coverage | 1.10x minimum on the full-limit stress payment |
| Credit, second lien | 720 minimum |
| Credit, first lien | 700 minimum |
| Second-lien leverage | Up to 70% CLTV, lines to $500,000 |
| Line size | From $50,000; first lien to $1,000,000 |
| Exposure | At most 5 loans or $2,500,000 per borrower |
| Reserves | None required |
| Seasoning | 6 months since the last note date and 6 months on title |
Borrower and credit
Foreign nationals and ITIN borrowers are not eligible. Mortgage history must show no 30-day late in the last 12 months. At least 48 months must have passed since a bankruptcy, foreclosure, short sale or deed in lieu. The lender’s own credit report sets the tier.
The borrowers on the line do not have to be the borrowers on the first mortgage. If the property sits in an LLC, the members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Entity vesting is allowed on investment property only, subject to lender program eligibility.
Property
Eligible types include single-family homes, PUDs, townhomes, two-to-four unit properties, warrantable and non-warrantable condominiums, and lots up to 10 acres. A two-to-four unit property can have at most one vacant unit.
These are outside the 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 and mixed-use. A property listed for sale in the prior two months is out, and so is a property with a solar lien. A declining-market flag lowers the leverage ceiling.
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).
Valuation and title
Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
Title work scales with the file. A first lien and any second lien above $400,000 need a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required.
How Much Room Does a Low First Leave?
Headroom is a simple subtraction. Take the combined cap times value, then subtract the first mortgage balance. What remains is the largest line the leverage test allows.
Work it in percentages of value. On a second lien the cap is 70% CLTV.
| Scenario | First balance | Cap | Room for the line |
|---|---|---|---|
| Older, heavily paid-down first | 30% of value | 70% | 40% of value |
| Mid-life first | 50% of value | 70% | 20% of value |
| Recent, high-leverage first | 65% of value | 70% | 5% of value |
Multiply the room by the appraised value to see the dollar line. The calculation is illustrative, and the lender’s own math governs.
Then check the minimum. Lines start at $50,000, so a property with thin room may fall below the smallest line available. The third row above shows the risk: leverage technically exists, but whether 5% of value reaches $50,000 depends on the property’s value, and on a lower-value rental the line may be too small to write.
Now stress the value. Say the first balance is 40% of today’s value, which leaves 30 points of room under the 70% cap. If the appraisal comes in 10% lower, the cap applies to a smaller number, so the first balance becomes a larger share of value. The room drops to 23 points of the original value. A declining-market flag, which lowers the ceiling by 5 points, takes more off.
An automated valuation or a full appraisal that lands below the owner’s number changes the answer. Run the headroom math at a value 5% to 10% under the owner’s estimate before choosing a line size.
How the Rent Test Works
The coverage ratio is gross monthly rent divided by the qualifying payment. The minimum is 1.10x.
The qualifying payment is not what you will pay. It is a stress payment: a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. It covers principal and interest only. Taxes and insurance are not part of it.
Two features of that test matter on a low-first file.
The full limit counts. The payment is sized on the whole line, even though the draw period is interest-only on the drawn balance. Bigger lines raise the stress payment, so coverage falls as the line grows. A rental that clears 1.10x on a $100,000 line can miss it on a $300,000 line.
The first mortgage payment is a question for the file. The lender’s coverage calculation governs how the first mortgage payment is treated on a second lien, so do not assume an answer. Confirm on the file how the lender treats the first-mortgage payment before choosing a line size.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser’s market rent comes from Form 1007. A lease in place is required, so a vacant or owner-used unit does not qualify.
Picture a duplex where the lease and the appraiser’s market rent agree. Coverage then depends only on how big the line is. If both numbers sit close to the 1.10x line, trimming the request, not arguing the rent, is the lever.
Draw Rules and Repayment
The line has a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, and the maturity is 30 years. The rate is variable, and the rate and pricing terms come with the lender’s disclosures.
Draw rules are tighter than most owners expect:
- 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.
This is not a standby reserve with a large unused balance. It is a mostly funded line that stays revolving for later draws.
Two cash-flow points follow from the structure. When repayment starts, the payment includes principal and rises from the interest-only level. And because the rate is variable, the payment can change after that.
A line is also not guaranteed to stay open at its full limit. The CFPB’s HELOC overview explains that a HELOC is an open-end line you can borrow against repeatedly. It also says a lender may decline further draws if the property’s value falls significantly. Plan for the later-draw feature as useful but conditional.
Keep the First or Replace It?
Keeping the first is not automatically right. Both paths pull equity, and they price different things.
| Question | Keep first, add a line | Cash-out refinance |
|---|---|---|
| First mortgage terms | Unchanged | Replaced with new terms |
| Size of cash need | Fits the room under the CLTV cap | Can be larger if leverage allows |
| Number of loans | Two | One |
| Payment behavior | Variable second lien | Set by the new loan |
| Later refinance | Second lien must be addressed | One loan to pay off |
A few tiebreakers help.
- Value the old first. If the first mortgage’s terms are better than what a replacement would carry, a second lien preserves that. Run the blended cost both ways.
- Size the need. A modest cash need against a large equity cushion suits a second lien. A need that exceeds the room under the cap points toward a refinance.
- Think about the next refinance. A second lien reduces the equity left for any later refinance. Whoever lends on the next first mortgage will have to deal with the line, either by paying it off or by subordination, depending on that lender.
- Check the credit tier. A borrower below 720 cannot use the second-lien lane. A 700 score only works on a first lien, which exists only on a rental with no mortgage.
Where the General Rule Breaks
First lien on a paid-off rental. The leverage steps change. At 740 or better, a first lien reaches 75% LTV on lines up to $500,000. From 700 to 739 it is 70% LTV. On lines above $500,000, up to $1,000,000, the first-lien ceiling is 65% LTV at 720 or better. These are first-lien loan-to-value figures, not combined. The first-lien lane exists only for a rental with no mortgage. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Exposure limits can cap the line. The 5-loan and $2,500,000 per-borrower limit counts loans with the program. An investor stacking lines on several rentals can hit the exposure limit before running out of equity.
LLC title. The LLC can stay on title, but the paperwork adds guarantor signatures and, where the title holder is not a borrower, a non-borrowing owner acknowledgment. Any missing signature can stall an entity file.
Condominiums. Warrantable and non-warrantable condominiums are eligible property types. Condotels are not. Confirm the unit’s classification before ordering the valuation.
Closed-end versus revolving. Some products marketed as DSCR home equity loans are closed-end seconds that fund as a lump sum. This program is the revolving line, with the draw rules above. Read the product description for the draw and repayment structure.
Setup costs. The CFPB’s HELOC brochure notes that setup costs resemble other mortgage costs, and that a lender may reduce a line if value drops. Both points carry over to a rental line, so budget for closing costs and read the lender’s disclosures.
Documents to Gather
A clean file has these items in hand before it goes to the lender:
1. The first mortgage statement, plus the note and security instrument for junior-lien language.
2. The current lease, and three months of rent receipts if the lease runs above market rent.
3. Entity documents, if the LLC holds title: articles, operating agreement and signature authority for each member.
4. The settlement statement from the purchase or last refinance, which documents both six-month clocks.
5. Hazard insurance covering both liens, plus flood coverage where the property needs it.
6. Identification and Social Security numbers for each guarantor.
7. Condominium information, if the property is a unit, to confirm the project is eligible.
Key Terms Defined
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Debt service coverage ratio (DSCR): gross monthly rent divided by the qualifying payment; this program’s minimum is 1.10x.
Draw period: the stretch when the borrower can take draws; here it is 5 years, interest-only on the drawn balance.
Lien position: the order in which loans are recorded against a property; the earlier recording is the first lien.
Qualifying payment: the stress payment used for the rent test, built on the full credit limit at the start rate plus 2 percentage points.
Seasoning: how long the owner has held the property and how long since its last purchase or refinance.
Frequently Asked Questions
Can a DSCR HELOC sit behind a first mortgage I want to keep?
Yes, that is the structure. The line is recorded as a standalone second lien and the first mortgage stays as it is, with its rate and term. The second lien requires a 720 score or better and is capped at 70% CLTV, subject to underwriting.
Do two six-month waiting periods apply before I can open the 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). A recent cash-out refinance resets the first clock.
Can the rental stay in my LLC?
Yes, on investment property, 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.
Which properties are excluded?
Rural-designated property, row homes, condotels, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use are out. So is a property listed for sale in the prior two months or one with a solar lien.
Does the line replace my income documents?
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 lease, the credit report and the valuation are all reviewed.
