The Quick Read: The limit is the lower of two tests: the equity left after the allowed combined leverage, and the largest line the rent can carry at a stress payment on the entire limit, unless three months of rent receipts support a lease above market. On a second lien, most files in Lendmire’s wholesale network cap out at 70% combined loan-to-value (CLTV) with a 720 score or better, on lines of $50,000 to $500,000, subject to underwriting.
- Equity test: value times the allowed percentage, minus every lien already recorded.
- Rent test: rent must reach a minimum 1.10x coverage against a stress payment on the whole line, not just the drawn amount.
- Lien position, credit tier and valuation path then set the ceiling.
- Lendmire arranges this product in 15 of its 16 licensed states, every licensed state except Tennessee.
A DSCR home equity line is a revolving line on a one-to-four-unit rental. The rent qualifies it. The owner’s tax returns, W-2s and personal income are not calculated, subject to lender guidelines. All figures below are ceilings and floors through select programs, not offers.
What Is a DSCR HELOC, Exactly?
It is a standalone second lien behind the first mortgage the owner keeps. On a rental with no mortgage, it is a standalone first lien. It is never closed with a purchase, never a third lien, and never a line on the owner’s own home or a second home.
The federal consumer-finance regulator defines a HELOC as an open-end line you can borrow against repeatedly, and equity as the home’s value minus what you owe. It also notes that a HELOC on a property that already carries a mortgage is a second mortgage. That is the structure here. The first mortgage stays untouched.
An LLC can hold title (investment property only). The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Key Terms Defined
Combined loan-to-value (CLTV): 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.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. The rate itself is not quoted here.
Draw period: the stretch when you can pull funds. Here it is 5 years, interest-only on the drawn balance.
Seasoning: how long you have held title, and how long since the last purchase or refinance.
Which Limit Binds First: Equity or Rent?
Whichever test produces the smaller number is your line. That is the whole answer, and it is why two owners with the same property value can walk away with very different limits.
The equity test. Multiply value by the CLTV cap. Subtract the first mortgage balance. What remains is the most the line can be on the equity side. The federal consumer-finance regulator’s HELOC booklet shows the same method: take a percentage of appraised value, then subtract what you owe. Use that for the method only. The percentage in the booklet is an illustration, not this program’s figure.
The rent test. Take rent used for lender review and divide it by the qualifying payment on the full limit. The result must reach 1.10x. Rent used for lender review is the lesser of the appraiser’s Form 1007 market rent and the lease, unless three months of receipts support a lease above market. The payment is principal and interest only. Taxes and insurance are not part of the qualifying payment.
Here is the catch. The stress test sits on the whole line, even though you pay only on what you draw. The federal consumer-finance regulator notes that HELOC payments during the draw period are often based on the balance. The coverage test is stricter than how you will actually pay. Rent that clears at a smaller line can fail at a bigger one.
On a second lien, the lender’s coverage calculation governs whether the first-mortgage payment is counted alongside the qualifying payment. Confirm on the file how the lender treats it before you rely on any number.
Leverage Tiers by Lien Position
| Lien position | Credit score | Max leverage | Line size |
|---|---|---|---|
| Second lien | 720+ | 70% CLTV | $50,000–$500,000 |
| First lien (no mortgage) | 740+ | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700–739 | 70% LTV | Up to $500,000 |
| First lien (no mortgage) | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
Below 720 there is no second-lien tier. A borrower who keeps a first mortgage can only take a second lien. 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. All of this is subject to underwriting.
Three Scenarios: Which Test Wins?
These use ratios and percentages only. The lender’s calculation governs.
| Scenario | Equity test | Rent test | Result |
|---|---|---|---|
| Equity-rich, weak rent | Allows a large line | Coverage falls short of 1.10x on full line | Rent sets a smaller line |
| Strong rent, thin equity | Allows a small line | Coverage clears 1.10x with room | Equity sets the line |
| Balanced | Allows a mid-size line | Coverage lands near 1.10x | Both near the same number |
Equity-rich, weak rent. Picture a long-held duplex with a low first mortgage. The CLTV cap leaves plenty of room. But rent at the lesser of market rent and lease covers the stress payment on a big line at only about 1.0x, unless three months of rent receipts support a lease above market. The fix is to cut the requested line until coverage reaches 1.10x. The structure rewards a smaller line over a bigger one that fails.
Strong rent, thin equity. Say you bought a four-unit and refinanced recently, so the first mortgage eats most of the 70% CLTV. Rent covers a large line easily. It does not matter. The equity test caps the line well below what the rent could carry.
Balanced. The first mortgage is modest, rent is solid, and the two caps land close together. This is the cleanest file, because neither test forces the line down.
Tip: if the numbers fail, the options are a smaller line, documented higher rent (three months of receipts for a lease above market), or a different structure such as a cash-out refinance.
How to Work Backward From Rent
1. Set rent used for lender review. Use the lesser of the Form 1007 market rent and the lease, unless three months of receipts support a lease above market.
2. Divide by 1.10. That gives the largest qualifying payment the rent can support.
3. Convert to a line size. The stress payment is a fully amortizing payment on the whole limit at a stressed rate set above the start rate, so the lender’s payment factor turns the qualifying payment into a maximum line.
4. Run the equity test. Value times the CLTV cap, minus the first mortgage.
5. Take the smaller number. Then check it against the program cap: $500,000 on a second lien, and the first-lien limits in the table.
Underwriting adjusts the result. Value or rent that comes in lower than expected shrinks the line.
What Lowers Your Number
- 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 on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
- Rent documentation. A lease in place is required. A two-to-four-unit property may have at most 1 vacant unit.
- Property type. Single-family, PUD, townhome, two-to-four units and condominiums are eligible. Rural-designated property, row homes, condotels, leaseholds, land trusts, age-restricted communities, mixed-use and properties listed for sale in the prior 2 months are not.
- 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 history. No 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Exposure. At most 5 loans or $2,500,000 per borrower with the program.
Draws, Repayment and Usable Cash
The draw period runs 5 years, interest-only on the drawn balance. After that, a 25-year fully amortizing repayment period begins, which together make up the 30-year maturity. The rate is variable.
Here is what the draw rule does to usable cash. 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.
So the biggest line is not automatically the right line. Most of it is borrowed on day one, and the whole limit is what gets stress tested. Take what the rental and your plan can carry. The CFPB warns that falling behind on a HELOC could cost you the home, and here the collateral is your rental.
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.
DSCR HELOC vs. Cash-Out Refinance vs. Personal-Income HELOC
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank HELOC on a rental |
|---|---|---|---|
| Reviewed on | Rent | Rent | Borrower’s DTI |
| First mortgage | Stays in place | Replaced | Stays in place |
| Entity title | LLC allowed | Per program | Varies by lender |
| Funds | Revolving line | Lump sum | Revolving line |
A cash-out replaces the first mortgage. A HELOC leaves it alone. If the existing first mortgage has terms worth keeping, the line is the cleaner tool. If not, the refinance may fit better.
NerdWallet reports that not every lender offers investment-property HELOCs, that requirements are strict, and that bank lines rest on the borrower’s debt-to-income ratio. That is where the rent-qualified version helps: self-employed owners and owners with many properties whose DTI would block a bank line. Large retail lenders that underwrite personal income run a different test.
For the personal-income version, see Lendmire’s piece How Much Can You Borrow on an Investment Property HELOC When Rental Income Qualifies You?. Do not blend the two products’ figures. The rules differ.

Documents for the File
- Lease and rent evidence, plus three months of receipts if a lease above market rent is claimed
- Most recent first-mortgage statement
- Hazard insurance covering both liens, and flood coverage where required
- Title or vesting documents; entity documents and guarantor ID if an LLC holds title
- A property list for the exposure check
- Government ID; borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Tax returns, W-2s, pay stubs and a DTI calculation are not part of a rent-qualified file, subject to lender guidelines. The rent, the lease, the credit report and the valuation are all documented.
Check one thing early. If the existing first mortgage is itself a DSCR loan, its documents may restrict junior liens.
Frequently Asked Questions
Do I need tax returns or W-2s for a DSCR HELOC?
No. The line qualifies primarily on property-level rental income covering the stress payment, subject to lender guidelines. The lender still reviews credit, title, valuation and the lease.
Can I borrow against a rental I just bought?
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). Both must be satisfied.
Does rent only have to cover what I draw?
No. Coverage is tested on a stress payment for the entire credit limit. That is stricter than your actual draw-period payment, so a smaller line sometimes clears when a larger one fails. At least 80% of the line (and never less than $50,000) is drawn at closing.
What if coverage lands below 1.10x?
The file generally needs a smaller line, documented higher rent, or a different structure. Rent counts at the lesser of market rent and the lease, unless three months of receipts support a lease above market.
Can my LLC hold the property?
Yes, on investment property. The members sign as guarantors. Entity details are reviewed per program requirements.
Choosing a Line Size
The right number is rarely the maximum. Every figure here is a ceiling or floor through select programs, subject to underwriting, and none is an offer or commitment to lend.
