The Quick Read: Your line size is the smallest of three limits: the combined-leverage ceiling on the property’s value after the first mortgage comes out, the program’s dollar cap, and the rent coverage test. On a second lien, the ceiling is typically 70% combined loan-to-value at a 720 credit score or better, with lines from $50,000 up to $500,000, subject to underwriting.
- Equity sets the size. Rent coverage is a gate on top of it.
- A first lien on a rental with no mortgage reaches 75% LTV at 740 or better.
- The rent must cover a stress payment on the entire line at a minimum 1.10x.
- Most of the line is funded on day one, so size it for a real need.
- Your LLC can stay on title, per select program guidelines.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving credit line secured by a rental you keep. Across Lendmire’s wholesale network, it is written as a standalone second lien behind your existing first mortgage. It can also be a standalone first lien on a rental with no mortgage.
DSCR means debt service coverage ratio. It measures whether the property’s rent covers the payment. The program qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It does not require tax returns, W-2s, pay stubs or a personal debt-to-income calculation.

How Do You Calculate the Maximum Line?
Start with value, multiply by the leverage ceiling, subtract what is already owed, then check the dollar cap. A federal consumer booklet describes the same logic for HELOCs generally: the CFPB’s HELOC booklet says lenders usually take a percentage of the home’s value and subtract existing mortgage balances.
Here is the sequence:
1. Get the value. Lines up to $400,000 typically use an automated valuation plus a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
2. Apply the ceiling. On a second lien, that is up to 70% CLTV at 720 or better. CLTV means the first mortgage balance plus the new line, divided by value.
3. Subtract the first mortgage. What is left is the room for the new line.
4. Check the cap. Second-lien lines run from $50,000 to $500,000.
5. Run the coverage test. More on that below.
Picture a vacation rental valued at $600,000 with a first mortgage on it. At 70% CLTV, total debt can reach $420,000. Whatever the first mortgage balance is comes out of that, and the remainder is your room. The first lien does most of the shrinking. A heavily financed property may leave little or nothing, which is why equity decides the size before rent ever does.
What Does a First Lien Change?
A first lien exists only on a rental with no mortgage. If you keep a first mortgage, a second lien is your only option here, and it needs a 720 score.
On a first lien, leverage is written as LTV, not CLTV. The tiers run like this, subject to underwriting:
| Credit score | Line size | Max LTV (first lien) |
|---|---|---|
| 740 or better | Up to $500,000 | 75% |
| 700 to 739 | Up to $500,000 | 70% |
| 720 or better | $500,000 to $1,000,000 | 65% |
First-lien lines run up to $1,000,000, but the second-lien cap stays at $500,000. If you are weighing a first-lien line above $500,000, plan around the 65% ceiling. A declining-market flag on the property can lower any ceiling by 5 points.
How Does the Rent Test Limit You?
The rent must cover a stress payment at a minimum DSCR of 1.10x. That payment is a fully amortizing one on the entire credit limit, at the start rate plus 2 percentage points. It is tested on the whole line, not just what you draw. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Taxes and insurance are not part of that qualifying payment. Confirm on the file how the lender treats the first-mortgage payment on a second lien, because the lender’s own coverage calculation governs.
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. On a two-to-four-unit property, at most one unit may be vacant.
This is where a business-run vacation rental gets tested. A lease is required, so a property that only books nightly stays needs a lease structure that fits the program. Ask before you plan around it. Platform payout history shows how the property performs, but the rent figure the lender uses follows the rule above.
A bigger line means a bigger stress payment. That can cap you below the equity ceiling even when the equity is there. A line sized to 1.10x coverage on the full limit is the real ceiling for many thin-margin properties.
Does Running It as a Business Change the Amount?
Not the math. It changes who signs and how the file reads. Your LLC can hold title on this investment-property program, per program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
The borrowers on the line do not have to be the borrowers on the first mortgage. That helps when the first loan sits in one name and the LLC now owns the property.
Personal use matters for a different reason. The IRS draws a line between a rental and a personal vacation home. IRS Publication 527 treats a dwelling as a home when your personal use exceeds the greater of 14 days or 10% of the days rented at a fair price. This program is for non-owner-occupied rentals, never a second home. If you use the house heavily yourself, the property may not fit. 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.
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.
How Do Draws and Repayment Work?
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 a 25-year fully amortizing repayment period begins, with a 30-year maturity. The rate is variable.
The structure shapes how much you should take. Income that swings with the season, plus a variable payment, makes a tighter cushion. When the interest-only period ends, the payment steps up because principal begins. Size the line to the repayment period, not the draw period.
A lender can also stop further advances if the property’s value drops significantly. The CFPB notes that HELOCs carry this freeze risk, so access to the full line is never certain. A line makes a poor foundation for a purchase you must close on a deadline.
Which Properties and Borrowers Are Outside the Program?
Eligible types include single-family homes, PUDs, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums, with lots up to 10 acres.
Several types you may own as vacation rentals fall outside it:
- Rural-designated property
- Condotels and row homes
- Leaseholds and land trusts
- Age-restricted communities and mixed-use property
- A property listed for sale in the prior 2 months
- A property with a solar lien
Eligible borrowers are U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. Credit needs a 720 on a second lien and 700 on a first lien, with no 30-day mortgage late in the last 12 months. No reserves are required. Each borrower is limited to 5 loans or $2,500,000 with the program.
This product is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What Is the Seasoning Rule?
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).
DSCR HELOC vs. Bank HELOC vs. DSCR Cash-Out
| Factor | DSCR HELOC | Bank HELOC | DSCR cash-out refi |
|---|---|---|---|
| Replaces first mortgage | No | No | Yes |
| Reviewed on | Rent coverage | Usually personal income | Rent coverage |
| LLC title | Allowed | Often restricted | Typically allowed |
| Structure | Revolving line | Revolving line | One lump sum |
NerdWallet says investment-property HELOCs exist but come with a smaller lender pool and tighter limits than a primary-home line, and multiple appraisals may be required. That is why many owners of rentals look to a rent-qualified line.
The bank version is a different product with its own rules. A cash-out refinance can be the better tool when you want to replace your first mortgage, need a bigger sum, or want fixed terms. A high-interest first mortgage you would rather not touch is the classic reason to keep it and add a line instead.
When Does This Not Fit?
A few situations send you elsewhere:
- Thin equity. If the first mortgage uses most of the 70% CLTV ceiling, there is little room left.
- Rent too light for the full-line stress payment. The test hits the entire limit, so a modest property may qualify for a smaller line than its equity supports.
- A need under $50,000. The program starts at that amount.
- A planned down payment. Draw rules and the freeze risk make a line a shaky source for a deadline. Lendmire’s article How Much Can You Borrow on a DSCR HELOC Draw as a Documented Rental Down Payment? covers that use.
- An ineligible property type from the list above.
The honest read: this works best when you hold meaningful equity, have rent that clears the stress test, and want to keep a first mortgage you like. For the full picture on how these loans work, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
- DSCR: the property’s monthly rent divided by the qualifying payment.
- CLTV: combined loan-to-value, meaning the first mortgage plus the new line, divided by the property’s value.
- Draw period: the stretch when you can borrow from the line and pay interest only on what you drew.
- Stress payment: the higher test payment on the full line that the rent must cover, not the payment you will actually make.
- Second lien: a loan that sits behind your first mortgage in repayment order.
Frequently Asked Questions
What is the most I can borrow on a second-lien DSCR HELOC?
Lines run up to $500,000, subject to underwriting. Your actual number is the lower of that cap and 70% CLTV on the value, minus your first mortgage. Credit must be 720 or better.
Does my LLC have to come off title?
No. Vesting in your LLC is allowed on this investment-property program, per program terms. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
Do I need tax returns?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It does not calculate your personal income. The lease, rent figures, credit report and valuation are all documented.
Can I use this on 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).
Can I draw only part of the line at closing?
No. At least 80% is drawn at closing, with a $50,000 minimum closing draw. After that, each draw is at least $5,000. Plan the line size around what you will actually use.
