The Quick Read: It depends on the lien: behind a first mortgage you keep, a line can reach 70% combined loan-to-value at a 720 score or better, up to $500,000, while a rental with no mortgage can reach 75% loan-to-value on a first lien at 740 or better, subject to underwriting through select programs. The rent qualifies the line, not your personal income. Your existing first mortgage stays where it is.
- Second lien: up to 70% combined loan-to-value, lines of $50,000 to $500,000, 720 credit score or better.
- First lien on a rental with no mortgage: up to 75% loan-to-value at 740 or better, 70% from 700 to 739, and 65% on lines above $500,000 (lines run to $1,000,000).
- Rent test: a minimum 1.10x coverage ratio on a stress payment for the whole line.
- Biggest trade-off: a variable rate, and most of the line is drawn at closing. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Key Terms Defined
- DSCR (debt-service coverage ratio): gross monthly rent divided by the payment the lender tests. A higher number means the rent covers the payment with more room to spare.
- HELOC (home equity line of credit): a revolving line secured by property. You draw funds, repay, and draw again within the program’s rules.
- Lien: a lender’s legal claim on the property. A second lien sits behind the first mortgage. A first lien sits in front.
- Combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by the property’s value. Loan-to-value (LTV) is the same idea with only one loan.
- Draw period: the years when you can borrow from the line and pay interest only on what you have drawn.
- Seasoning: the waiting period a lender wants after you buy or refinance a property.
How Is the Maximum Line Calculated?
Leverage sizes the line. Take the property’s value, multiply by the allowed combined loan-to-value, and subtract every loan already recorded against it. Rent decides whether you qualify, and equity decides how much you can reach.
The federal consumer finance agency’s HELOC booklet uses the same method for home lines. It sets the credit limit as a percentage of the home’s value, then subtracts the mortgage balance. Rental lines apply tighter percentages.
Here is the math in percentages, with the property’s value as 100. Say you hold a second-lien line at 70% CLTV. A first mortgage at 40% of value leaves 30 points of room. A first mortgage at 60% leaves 10 points. A first mortgage at 70% or more leaves none.
| Second-lien scenario | Ceiling | Room for a line |
|---|---|---|
| First mortgage at 40% of value | 70% CLTV | About 30% of value |
| First mortgage at 60% of value | 70% CLTV | About 10% of value |
| First mortgage at 70% or more | 70% CLTV | — |
A rental with no mortgage uses the first-lien tiers in the next section instead. Two cautions apply to the table. The line starts at $50,000, so thin room may not reach the minimum. And a declining-market flag on the property lowers the ceiling by 5 points.
What Sets the Dollar Ceiling?
Dollar caps sit on top of the percentages. On a second lien, lines run from $50,000 to $500,000. On a first lien, lines run to $1,000,000, but the percentage drops as the line grows.
Here is how the first-lien tiers work on a rental with no mortgage:
- 740 or better: up to 75% LTV on lines up to $500,000.
- 700 to 739: up to 70% LTV on lines up to $500,000.
- Lines above $500,000, to $1,000,000: 65% LTV at 720 or better. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
A second lien never goes above 70% CLTV, and there is no second-lien tier below a 720 score. If you keep a first mortgage, a second lien is often a strong option. A first lien exists only on a rental with no mortgage.
Per-borrower limits cap a portfolio investor too. The program allows at most 5 loans or $2,500,000 per borrower. These figures are ceilings and floors, never offers, and every file is underwritten individually.
How Does the Rent Test Work?
The rent test is a minimum 1.10x coverage ratio on a stress payment. The lender divides gross monthly rent by a fully amortizing payment on the entire credit limit, calculated at the start rate plus 2 percentage points. Taxes and insurance are not part of that qualifying payment. The lender’s own calculation governs, so treat any arithmetic as illustration.
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 must be in place. A two-to-four-unit property can have at most one vacant unit. On a second lien, confirm on the file how the lender treats the first-mortgage payment, because that treatment shapes the coverage number.
The structure is business-purpose lending for non-owner-occupied rentals. The line is reviewed differently from a standard owner-occupied mortgage. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs, or personal income calculation.
Title can stay in your LLC, subject to 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 need not match the borrowers on the first mortgage.
What Does the File Need?
The file needs a lease, a credit report, a valuation, and clean title. Across the wholesale network Lendmire works with, this program is one of the lighter-documentation options for pulling equity, but it is still a documented file. The rent, the lease, the credit report and the valuation are all verified.
Valuation. 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 the alternative. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted. NerdWallet notes that rental lines can involve multiple appraisals, so budget for the valuation step.
Credit. A second lien needs a 720 score. A first lien needs 700. The tier comes from the lender’s own report. The program looks for no 30-day mortgage late in the last 12 months and 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
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).
Property. Eligible types include single-family, planned unit developments, townhomes, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. Outside the program are these:
- rural-designated property
- row homes
- condotels
- commercial or agricultural property
- leaseholds and land trusts
- age-restricted communities
- hobby farms
- modular and log homes
- land contracts
- mixed-use property
- 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.
Where it is offered. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. The line is placed through a wholesale lender.
DSCR HELOC or Another Way to Pull Equity?
A DSCR HELOC fits when you want to keep a first mortgage and open no personal income file. Other products fit other goals. This table compares what each one tests, as those products are generally structured.
| Factor | DSCR HELOC | DSCR cash-out refinance | Personal-income HELOC |
|---|---|---|---|
| Reviewed on | Rent coverage | Rent coverage | Owner’s income |
| First mortgage | Stays in place | Replaced | Stays in place |
| Structure | Revolving line | Lump sum | Revolving line |
| LLC on title | Allowed, per program | Often allowed | Often excluded |
If you need a large lump sum or want to restructure the first mortgage, a cash-out refinance is the usual route. Lendmire’s DSCR cash-out refinance guide covers that product, so this article stays on the line.
The Pros
Here is what the structure does well.
- The first mortgage stays. If your first lien is one you like, a second-lien line pulls equity without touching it.
- Rent qualifies it. Your personal income is never calculated. That helps owners whose tax returns understate their income.
- Entity-friendly. The LLC can stay on title, so you do not need to move the property into your name.
- Low cash friction. No reserves and no cash to close are required, subject to underwriting.
- Interest-only draw period. You pay interest only on the drawn balance for 5 years, which keeps the early payment lower than a fully amortizing loan.
- Reusable. After closing, later draws are at least $5,000 each, so you can fund a rehab or a down payment on the next rental as needs arise.
The Cons
The cons are real, and several differ from what generic HELOC articles say.
- You cannot draw only what you need. 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. You pay interest on most of the line from day one.
- The rate is variable. Your cost can move after closing, and you cannot lock it in.
- The payment steps up. After the 5-year interest-only draw period comes a 25-year fully amortizing repayment period, with a 30-year maturity. The required payment rises when repayment begins.
- Fewer lenders and tighter leverage. NerdWallet explains that fewer lenders offer these lines and that you can borrow less than against a primary home. The caps above bear that out.
- Narrow eligibility. The excluded property types, the six-month clocks and the 15-state footprint rule out many files.
- More debt on one asset. The line is secured by the property. Selling the rental means paying the line off from the proceeds. Missed payments put the property at risk.
- Passing the test is not profit. A 1.10x coverage ratio leaves thin room, and taxes and insurance are not in the qualifying payment. Vacancy and repairs come on top.
If you use the funds for a purchase or improvement, remember this: 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.
How Do You Stress-Test a Full Draw?
Run the full line, not the part you plan to use, because 80% or more is drawn on day one. Start with the lender’s qualifying test, which assumes you borrow the entire limit on a fully amortizing basis. That payment is usually higher than what you actually owe during the interest-only years.
Then test three pressures yourself:
1. Vacancy. Cut the rent by one month a year and see whether coverage still works.
2. Rate movement. The rate is variable, so ask whether the property still covers the payment if the rate rises.
3. The step-up. When repayment starts after year 5, the payment amortizes. Check coverage against that payment now, not later.
Think of it as two coverage numbers. The first is the number you qualify on. The second is the number you live on after taxes, insurance and repairs. The second can be much thinner than the first.
The main alternative to weigh is a cash-out refinance. The line wins if the first mortgage is worth keeping. The refinance wins if you want one fixed-structure payment and a lump sum.
Who Should Use It, and Who Should Skip It?
Good fit:
- You own a one-to-four-unit rental with a 720 score or better, and you want to keep a first mortgage you like.
- The property has a lease in place and enough room under the CLTV ceiling to reach the minimum line.
- You can carry a variable payment and the later step-up.
Skip it if:
- The property is rural, a condotel, a row home or held on a leasehold.
- You bought or refinanced in the last 6 months.
- You want to draw a small amount at closing. The 80% rule makes that impossible.
- Your score is below 700, or between 700 and 719 with a first mortgage you plan to keep. A second lien needs 720.
For LLC-held rentals, Lendmire’s HELOC rules for LLC-titled borrowers covers the title questions in more depth. If you are buying your first rental, Lendmire’s piece on investment property HELOC requirements for first-time investors explains why seasoning matters. For the wider picture, see the complete DSCR loans guide.
What Are the Steps?
1. Pull your first-mortgage balance and estimate the property’s value.
2. Divide the balance by value, then see how much room remains under the 70% CLTV ceiling on a second lien. With no mortgage, use the first-lien LTV tiers instead.
3. Check your lease against market rent and confirm the property type is eligible.
4. Confirm both 6-month clocks and your credit tier.
5. Gather the first-mortgage statement, insurance declaration, vesting deed, lease and entity documents.
6. Review the full-line stress test before you commit. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Frequently Asked Questions
Can I use a DSCR HELOC if my rental is in an LLC?
Yes, subject to program terms. The program allows vesting in your LLC for investment property. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. Many personal-income investment lines exclude LLC-held property, so this is a real difference.
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). A brand-new purchase has to wait.
Does the first mortgage payment count in the rent test?
Confirm on the file how the lender treats the first-mortgage payment on a second lien. The qualifying payment itself is a fully amortizing payment on the entire credit limit at a stress rate. It leaves out taxes and insurance. The lender’s calculation governs, and the arithmetic here is illustrative.
Can I draw only part of the line at closing?
No. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. After that, each later draw is at least $5,000. If you want a small balance and a large unused line, this program is the wrong fit.
Does a 1.10x coverage ratio mean I will be approved?
No. Coverage is one test among several. Value, combined leverage, credit tier, seasoning, property type and borrower limits all apply. Rent covering the stress payment does not make the property eligible or the line available.
