The Quick Read: It depends on two limits, and the smaller one sets your line: the equity ceiling, which is combined loan-to-value of up to 70% on a second lien at a 720 credit score or better, and the rent test, which needs rent of at least 1.10 times a stress payment on the whole credit limit, subject to underwriting. Your personal income never enters the calculation. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
- A second lien behind a first mortgage you keep runs from $50,000 to $500,000, with the first mortgage balance counted inside the 70% combined ceiling.
- A first lien, which exists only on a rental with no mortgage, reaches 75% loan-to-value at 740 or better and 70% at 700 to 739, on lines up to $500,000; lines above $500,000 run to $1,000,000 at a 65% ceiling.
- Because the rent test counts the full limit, a bigger line needs more rent.
- All figures are ceilings and floors through select programs, not offers, and the lender’s own calculation governs.
Why Two Limits Decide the Answer
The equity ceiling and the rent test are separate gates, and each one caps the line. On a DSCR HELOC, either one can set the limit, so check both. The rent test has one exception: a lease above market rent counts when three months of rent receipts support it.
No federal rule sets these limits. A DSCR HELOC is a lender-set product, so the ceilings come from each investor’s guidelines. Other programs, and lenders, will differ.
Lendmire is a broker. It arranges the line through a wholesale lender, and the lender reviews the file and decides.
The Equity Ceiling: Value, Lien Position and Credit Score
The equity ceiling is a percentage of the property’s value, and your credit score and lien position pick the percentage. Combined loan-to-value (CLTV) means the first mortgage balance plus the new line, divided by value. On a first lien with no mortgage, it is plain loan-to-value (LTV).
The tiers through select programs, subject to underwriting:
| Lien position | Credit score | Ceiling | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
A few rules sit behind the table. A second lien needs a score of 720 or better, and the program has no second-lien tier below that. A first lien exists only on a rental with no mortgage, and a borrower who keeps a first mortgage can take only a second lien. A declining-market flag lowers the ceiling by 5 points, and some locations carry a lower ceiling than that.
The sizing steps are simple:
1. Multiply value by the ceiling for your tier. That gives the total debt the property can carry.
2. Subtract the first mortgage balance. Whatever remains is the most the equity allows.
3. Compare that result with the rent test and with the program’s line size range. The line can be no larger than the lowest of the three.
Take a rental whose first mortgage sits at 50% of value. On a second lien at 70% CLTV, that leaves 20 points of value as the equity limit. If the first mortgage sits at 65% of value, only 5 points remain. On many properties, that falls under the $50,000 minimum line, so the equity limit alone can end the request.
The Rent Test: Why a Bigger Line Needs More Rent
The rent test asks whether the property’s gross monthly rent covers a qualifying payment by at least 1.10 times. That 1.10x is the minimum for this program. It is a select-program floor, and other programs set theirs differently.
The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit, calculated at a stressed rate above the start rate. Taxes and insurance are not part of it. Drawn or not, the whole limit counts.
Commercial lending often defines debt service coverage with net operating income. This program uses gross rent instead. Keep the two definitions apart when you compare numbers from different sources.
Rent is the lesser of the appraisal’s Form 1007 market rent and the lease, unless three months of rent receipts support a lease above market. A lease in place is required. A two-to-four-unit property may have at most one vacant unit.
Because the payment grows in proportion to the limit, the line your rent supports grows in proportion to rent. If rent is 10% higher, the line the rent supports is about 10% larger, all else equal. That gives a rough way to gauge the rent limit: dividing rent by 1.10 gives the largest qualifying payment the rent can carry.
On a second lien, confirm on the file how the lender treats the first mortgage payment inside the coverage calculation. That detail changes the result, so treat the rough gauge above as a starting point, since the lender’s own calculation governs.
Which Limit Binds? Four Common Shapes
The binding limit tells you what to change. This table uses percentages and ratios only. Each row is illustrative, and underwriting decides.
| Situation | Equity limit | Rent limit | Binding limit |
|---|---|---|---|
| Second lien, first mortgage at 50% of value, modest rent | 20 points of value (70% CLTV) | Supports less than that | Rent |
| Second lien, first mortgage at 65% of value, strong rent | 5 points of value (70% CLTV) | Supports more than that | Equity, often under the minimum line |
| First lien, no mortgage, 740 or better | 75% LTV (first lien only) | Depends on rent | Whichever is lower |
| First lien above $500,000, 720 or better | 65% LTV | Depends on rent | Often the 65% LTV ceiling |
In row one, the owner has equity but weak rent for the size of line. Raising rent or asking for a smaller line fixes it. In row two, rent is fine, but the first mortgage has used up the combined ceiling, so only paying down the first mortgage or waiting for value to rise helps.
Row three is the cleanest case. A paid-off rental at the top tier can reach 75% LTV on a first-lien line up to $500,000, and rent then sets the practical limit. A second lien never reaches that figure. Row four is the trap for larger requests. First-lien lines above $500,000 drop to 65% LTV, so asking for more can produce a smaller percentage of value. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
What Raises or Lowers Your Number
Several inputs move the line, and some are in your hands.
- Credit score. A first lien at 740 or better gets 75% LTV, while 700 to 739 gets 70%. A second lien needs 720 and tops out at 70% CLTV.
- First mortgage balance. Every dollar owed on the first mortgage comes straight out of a second-lien line.
- Rent documentation. A lease above market counts only when three months of receipts support it.
- Line size. A smaller limit lowers the qualifying payment, so a request that fails on rent can pass at a lower limit.
- Location flags. A declining-market flag lowers the ceiling by 5 points.
- Property type. Single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums are eligible. Among these eligible types, the leverage tiers above govern, with no separate figure for any one type. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Some properties fall outside this lane altogether: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts and age-restricted communities. So do hobby farms, modular and log homes, land contracts, mixed-use property, a property listed for sale in the prior two months, and a property with a solar lien. Among eligible properties, the lot can be up to 10 acres.
What “Property Income Alone” Still Checks
The rent replaces the income file, but it does not replace the rest of the file. There is no traditional personal-income documentation: no W-2s, pay stubs or debt-to-income ratio. The lender still pulls credit, reads the lease, and orders a valuation. Title and insurance get documented too.
Mortgage history matters. The program looks for no 30-day mortgage late in the last 12 months. It also looks for 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
Valuation depends on line size. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted. The value drives the equity ceiling, and the appraiser’s market rent feeds the rent test.
Hazard insurance must cover both liens, with flood coverage where required. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
Seasoning, Draws and Exposure Limits
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).
Draws work in a fixed pattern. At least 80% of the line is drawn at closing, and the closing draw is at least $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. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
Each borrower can carry at most 5 loans or $2,500,000 with the program. 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 on this program.
Second Lien or Cash-Out Refinance?
A DSCR cash-out refinance replaces the first mortgage and tests rent against the larger new payment. A second-lien line leaves the first mortgage alone and adds a separate payment, with the combined ceiling holding total debt to 70% of value.
The first mortgage matters here. Its loan documents may restrict a second lien, so read them before you apply. A second lien also leaves a low-cost first mortgage in place, which a refinance would replace.
The payment risk stays with you. A BiggerPockets Rookie reply stresses cash flow that covers the added payment and more than one exit. Equity left in the property is the cushion if values slip, so a higher combined ratio leaves less of it.
Can an LLC Hold Title?
Yes, on this program. Vesting in the owner’s LLC is allowed on investment property, and 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 be the borrowers on the first mortgage. All of this is subject to lender program requirements.
That differs from what BiggerPockets lender commenters describe for bank investment HELOCs, which they say generally want individual title. Banks that offer rental HELOCs at all are limited, and a BiggerPockets discussion shows investors being turned down. A bank line on personal income is a different product from this one.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. It is never offered on an owner-occupied home or a second home. 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.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment, which on this program is at least 1.10x.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Qualifying payment: A fully amortizing payment on the entire credit limit at a stressed rate, with taxes and insurance left out.
Draw period: The 5 years in which you borrow against the line and pay interest only on what you have drawn.
Lien position: Whether the line sits behind a first mortgage (second lien) or stands alone as the only loan on the rental (first lien).
Seasoning: The minimum time since a purchase, a refinance, and the start of ownership before the line is available.
Where to Start
Start with three numbers: the property’s value, the first mortgage balance, and the rent. Work the equity ceiling first, then back-solve the rent limit, then check the line against the $50,000 minimum. The lower result is your realistic figure. The complete DSCR loans guide covers the wider program picture.
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals.
Frequently Asked Questions
Can I borrow more than my rent supports if I have plenty of equity?
No. The rent test runs on the entire credit limit, so a limit that rent cannot cover fails no matter how much equity sits in the property. The line is the lower of the equity limit and the rent limit, unless three months of rent receipts support a lease above market. A smaller request can pass when a larger one fails, subject to underwriting.
What is the largest second-lien line, and what does it need?
A second lien runs up to $500,000, with a 70% combined ceiling (CLTV) at a 720 credit score or better. The first mortgage balance counts inside that 70%, so the room left over is often smaller than the cap. Through select programs, and subject to underwriting.
Does my rental have to be free and clear for a first-lien line?
Yes. A first lien exists only on a rental with no mortgage. It reaches 75% LTV at 740 or better, or 70% LTV from 700 to 739, on lines to $500,000, and 65% LTV at 720 or better on lines above that, up to $1,000,000. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
How long must I own a rental 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). Both are checked in the file, and the lender’s guidelines govern.
Does a DSCR HELOC need tax returns or reserves?
No traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio are needed, and no reserves or cash to close are required. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, the lease, title, insurance and a valuation are still documented.
