The Quick Read: It depends on the equity left after your first mortgage and on how much rent the property earns, because the line is the smaller of two ceilings: combined leverage up to 70% of value on a second lien, and a rent test of 1.10x run against the entire credit limit, with lines running from $50,000 to $500,000. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
- The equity ceiling on a second lien is 70% combined loan-to-value (CLTV), at a 720 credit score or better, on an investment property.
- A rental with no mortgage can take a first-lien line instead, up to 75% loan-to-value (LTV) at 740 or better.
- The rent test uses the full line, not only the amount you draw.
- One rental supplies all of the equity and all of the rent. There is nothing else to pool.
- These are ceilings and floors through select programs, subject to underwriting. They are never offers. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
What Is a DSCR HELOC on a Rental?
A DSCR HELOC is a revolving line of credit secured by a rental you already own. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your own income is never calculated.
DSCR stands for debt service coverage ratio. It compares the rent to the debt payment. A HELOC is a home equity line of credit, meaning you borrow against equity as you need it, up to a limit.
Here is the structure that matters. The line is a standalone second lien behind the first mortgage you keep. If the rental has no mortgage, it is a standalone first lien. It is never a third lien. It is never closed together with a purchase. It is never a line on your own home.
Your LLC can stay on title. The members sign as guarantors, and the borrowers on the line do not have to match the borrowers on the first mortgage. That is subject to program terms, and the lender confirms it on each file.
One naming trap deserves a warning. Some lenders sell an investment-property HELOC underwritten on your personal income and debt-to-income ratio. That is a different product with different rules. This article covers the rent-qualified line only.
How Much Can One Rental Support?
The amount comes from a formula, then two limits. Take the property value, multiply by the allowed combined leverage, and subtract every lien already on the property. Then check the result against the program’s line-size band and against the rent test.
Being a first-time investor does not change the formula. It changes your margin for error. NerdWallet notes that rental HELOCs are harder to get than lines on a primary home, because lenders see higher default risk on rentals. It adds that many lenders cap leverage below 70%.
Across the wholesale network Lendmire works with, the second-lien ceiling is 70% CLTV at 720 or better, subject to underwriting. Think of it as two gates in a row. Equity is gate one. Rent coverage is gate two. The smaller number wins.
Gate One: The Equity Ceiling
Equity sizes the line first. CLTV adds your first-mortgage balance to the full new credit limit, then divides by value. Sizing a line “for later” uses up room today, because the whole limit counts even if you draw only part of it.
On a second lien, the numbers are simple. At 720 or better, combined leverage runs up to 70% CLTV on lines from $50,000 to $500,000. Below 720 there is no second-lien tier. A borrower who keeps a first mortgage can only take a second lien.
A first lien works differently. It exists only on a rental with no mortgage, and its floor is a 700 credit score. Leverage by credit tier looks like this:
- 740 or better: up to 75% LTV on lines to $500,000.
- 700 to 739: up to 70% LTV on lines to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV at 720 or better. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Write it as LTV on a first lien and CLTV on a second. The labels matter. A declining-market flag on the property can also lower the ceiling by 5 points.
Value comes from a valuation. Lines up to $400,000 can use an automated valuation (confidence score of 85 or better) plus a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted. NerdWallet also points out that some rental lines require multiple appraisals, so the value used can differ from the number you had in mind.
Gate Two: The Rent Test
Rent sets a second ceiling, and with one rental it can bind before equity does. The minimum DSCR is 1.10x. That means gross monthly rent divided by the qualifying payment must reach at least 1.10. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The qualifying payment is not what you will actually pay at first. It is a fully amortizing principal-and-interest payment on the entire credit limit, at the start rate plus 2 percentage points. It is a stress payment. Taxes and insurance are not part of it.
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 can have at most one vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs, and any math you do at home is illustrative.
Here is the practical effect. The stress payment grows in step with line size. If the rent covers a given line at 0.90x, trimming that line by about a fifth brings coverage near 1.10x. Equity may have allowed more. Rent does not.
Three Worked Scenarios
These use percentages of value and coverage ratios only. They are illustrations, not quotes.
Scenario one: seasoned rental with a modest first mortgage. Say your first mortgage is 40% of value and your score is 720 or better. A 70% CLTV ceiling leaves 30 points of value in room. Your line can be up to that amount, inside the $50,000 to $500,000 band. If rent covers that line at around 1.25x on the stress payment, both gates clear. Final terms are subject to underwriting.
Scenario two: a recent purchase financed at high leverage. Picture a first mortgage at 65% of value. That leaves 5 points of room under the 70% ceiling. On a modest rental, five points of value may fall below the $50,000 minimum line. No line fits. Not ideal, but it is the math, and paydown or appreciation changes it over time.
Scenario three: a paid-off rental with thin rent. Run the numbers on a rental with no mortgage and a 740 score. Equity allows up to 75% LTV. But rent covers a line of that size at only 0.95x. The line must shrink until coverage reaches 1.10x. The equity said yes to more; the rent said no. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Notice the shared lesson. The first mortgage uses up room first, and rent decides how much of the remaining room you can actually use.
Can You Even Qualify?
Many first-timers should check their situation against the table below before sizing anything. Your situation decides which door is open.
| Your situation | What it means |
|---|---|
| No rental owned yet | Not available; the line sits on a rental you own |
| Just bought or refinanced | Waits out seasoning (rule below) |
| Seasoned rental, first mortgage kept | Second lien, 720 minimum |
| Seasoned rental, no mortgage | First lien, 700 minimum |
| Title held in an LLC | See the note below the table |
The seasoning rule is written as two six-month clocks. 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).
On an LLC, vesting is allowed on investment property, subject to program terms. Members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment.
Other file requirements are straightforward. Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. Mortgage history needs no 30-day late in the last 12 months. The program waits 48 months after a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. A borrower can hold at most 5 loans or $2,500,000 of exposure with the program.
Property type matters too. Single-family, PUD, townhome, two-to-four units and condominiums are eligible property types. Rural-designated property, row homes, condotels, leaseholds, land trusts and a property listed for sale in the prior 2 months are outside this program.
Why Your Line May Come Out Smaller Than Expected
Check these before you assume a number:
- The first mortgage ate the room. Every point of existing leverage comes off the ceiling.
- The full limit counts. Combined leverage is measured on the whole line, drawn or not.
- The valuation came in lower. An automated valuation or appraisal sets the value, not a listing site.
- Rent is below the lease. The appraiser’s market-rent opinion can cap the rent that counts.
- The stress payment is larger than your real payment. Coverage is tested on the whole limit.
- A declining-market flag. That lowers the ceiling 5 points.
- The minimum line size. Lines start at $50,000, so thin equity can fall short.
Draw Rules That Change the Real Number
You cannot take a small line and leave it mostly unused. At least 80% of the line is drawn at closing, and that 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 sizing a line is also sizing the debt you take on at the start. The draw period is 5 years of interest-only payments on the drawn balance. A 25-year repayment period follows, with a 30-year maturity. The rate is variable.
How Does It Compare With Other Ways to Tap Equity?
A DSCR HELOC sits beside your first mortgage. A cash-out refinance replaces it.
| Item | DSCR HELOC | Cash-out refinance | Line on your own home |
|---|---|---|---|
| Collateral | The rental | The rental | Your residence |
| First mortgage | Kept | Replaced | Not touched |
| Reviewed on | Rent coverage | Rent coverage | Personal income |
| Product type | Revolving line | One lump sum | Owner-occupied product |
The row that matters for a one-rental investor is collateral. A line on your home puts your residence behind the borrowing. A DSCR HELOC keeps the risk on the rental. That cuts both ways, because the rental is also your only investment.
The Honest Risks With One Rental
Concentration is the big one. All the equity, all the rent and all the risk sit on a single property. If the tenant leaves, the rent test that qualified the line stops looking like it did on closing day.
Leverage also compounds. Pulling equity to fund a down payment on rental number two thins the cushion on rental number one. That can be a sound move, and it can also hurt in a downturn. Run the numbers with a vacancy before you draw.
And fewer lenders write these lines. Investors on a BiggerPockets thread describe calling around because many banks decline. That is one reason brokers compare across lenders.
For the full picture of how rent-qualified investor financing works, the complete DSCR loans guide covers the basics behind these tests.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent divided by the qualifying payment. Here the minimum is 1.10x.
CLTV (combined loan-to-value): Your first-mortgage balance plus the full new line, divided by the property’s value.
Lien position: Who gets paid first if the property is sold. A second lien sits behind the first mortgage.
Draw period: The 5-year stretch in which you can draw from the line and pay interest only on the drawn balance.
Seasoning: The waiting time after a purchase, refinance or title transfer before the property can carry this line.
Stress payment: The fully amortizing payment on the whole limit that the rent test uses. It is not your actual payment.
Frequently Asked Questions
Can I get a DSCR HELOC if I own only one rental and my own home?
Yes, if the rental itself meets the program. The line sits on the rental, never on your own home. Equity, rent coverage, credit and seasoning are all measured on that one property. Your residence is not part of the collateral.
How long must I own the rental before applying?
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 are subject to underwriting. Check the dates on your own closing documents before applying.
Does a higher credit score raise how much I can borrow?
Mostly it opens a tier. On a second lien the cell is 70% CLTV at 720 or better, and below 720 there is no second-lien option. On a first lien, a 740 score reaches 75% LTV while 700 to 739 reaches 70% on lines to $500,000. These are ceilings through select programs, not offers. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
What happens if my tenant leaves?
A lease in place is required to qualify, so vacancy during the application can stop the file. After closing, the line stays open under its terms. Your payments still come due, so plan reserves of your own even though the program requires none. Many investors model a vacancy before drawing.
Can I use the line to buy my next rental?
Many investors use equity that way, but remember what it costs. Drawing against rental one raises its combined leverage and adds a payment to its cash flow. That payment also counts against you when you finance rental two, so check coverage on both properties.
