The Quick Read: It depends on three limits, and the smallest one sets your number: the equity left under a 70% combined loan-to-value ceiling after your first mortgage, a $500,000 line-size ceiling on a second lien, and a rent-coverage test of 1.10x run against the full credit limit, not just the amount you draw, subject to underwriting.
- On a second lien, the line plus your first mortgage typically tops out at 70% of the rental’s value, at a 720 credit score or better.
- On a first lien (a rental with no mortgage), leverage reaches 75% at 740 or better, and 70% from 700 to 739.
- Lines start at $50,000, and at least 80% of the line is drawn at closing.
- The proceeds have to go to business obligations, not personal ones.
Key Terms Defined
DSCR (debt service coverage ratio) is the rental’s gross monthly rent divided by the qualifying payment. A result of 1.10x means rent is 10% larger than that payment.
CLTV (combined loan-to-value) is your first mortgage balance plus the new line, divided by the property’s value.
Second lien means the line sits behind your first mortgage, which you keep in place.
Stress payment is the payment the lender uses to test the line. It is a fully amortizing payment on the entire credit limit, calculated at a higher rate than the line’s starting rate. The rate itself comes with the lender’s disclosures.
Draw period is the window when you can borrow from the line and pay interest only on what you have drawn. Here it lasts 5 years.
What Is a DSCR HELOC, and How Is It Different From a Bank HELOC?
A DSCR HELOC is a revolving home equity line on a non-owner-occupied one-to-four-unit rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. No traditional personal-income documentation, W-2s or pay stubs go in the file, and no personal debt-to-income ratio is calculated.
It is written one of two ways. It can be a standalone second lien behind the first mortgage you keep. Or it can be a standalone first lien on a rental that has no mortgage. It is never closed together with a purchase, never a third lien, and never a line on your own home or second home.
The owner can keep the LLC on title, subject to lender program eligibility. The members sign as guarantors. The borrowers on the line do not need to match the borrowers on the first mortgage.
That is the real difference from the line your bank offers on your primary residence. A bank line leans on your income and your home. This one leans on the rent and the rental’s equity.

How Much Room Do You Have? The Equity Ceiling
Your first limit is simple arithmetic: value times the CLTV ceiling, minus every lien already on the property. Across the programs we place files with, a second-lien line on a rental stops at 70% CLTV, and only at a 720 score or better. Below 720 there is no second-lien option.
The ceiling counts your whole combined debt, not just the new line. If you owe half the property’s value, the new line can add at most another 20% of value.
Here is how that plays out at 70% CLTV on a second lien, by first mortgage size:
| First mortgage (% of value) | Room for the line (% of value) |
|---|---|
| 40% | 30% |
| 55% | 15% |
| 65% | 5% |
| 70% or more | None |
Two points trip people up. First, the full credit limit counts toward CLTV, not only the amount you plan to draw. Second, a recently bought or heavily financed rental often has no room at all. Primary-home lines can reach higher combined leverage than a rental can. Rentals are tighter, and an investment line here stops at 70% CLTV on a second lien.
A declining-market flag on the property can lower the ceiling by 5 points. All figures are ceilings, not offers, and each file is underwritten individually.
The Line-Size Ceiling
On a second lien, lines run from $50,000 up to $500,000. If you have a high-value rental with a small first mortgage, the $500,000 ceiling binds before equity does.
A first lien works differently. On a rental with no mortgage, lines up to $500,000 reach 75% LTV at 740 or better and 70% LTV from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Exposure limits apply too. The program allows at most 5 loans or $2,500,000 per borrower. Rural-designated property, condotels, row homes and leaseholds are outside it. So are commercial or agricultural property, land trusts and mixed-use buildings. Single-family, townhomes, PUDs, two-to-four units and condominiums are eligible property types.
A two-to-four-unit building can have at most 1 vacant unit. A property listed for sale in the prior 2 months is out. In practice, that rules out a lot of recent flips and listings.
The Coverage Test: Why Rent Can Cap the Line Even When Equity Is Ample
This is the limit that surprises business owners. The lender tests a fully amortizing payment on the entire credit limit, not on what you draw. Rent divided by that stress payment must reach 1.10x.
A few details matter for sizing:
- Rent is the lesser of the appraisal’s market rent (Form 1007) and the lease, unless three months of receipts support a lease above market.
- The qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not in it.
- A lease in place is required.
- On a second lien, confirm on the file how the lender treats the first-mortgage payment. The lender’s own coverage calculation governs.
The result is a ceiling that moves with the rent. A thin-rent duplex with 50% equity can hit the coverage limit well before it hits the equity limit. A larger line means a larger stress payment, so asking for less is the lever you control.
How Do You Size the Line to the Debt You Want to Pay Off?
Work it in four steps, and the smallest result is your answer.
1. Add up the payoff. Total the business debts you want gone, using current payoff letters rather than statement balances.
2. Check equity. Value times 70% (second lien), minus the first mortgage. Does the room cover the payoff?
3. Check coverage. Does the rent clear 1.10x against a stress payment on that full limit, not just the payoff?
4. Check the line floor. Lines start at $50,000, and at least 80% of the line is drawn at closing, never less than $50,000.
Picture a rental with a first mortgage at 55% of value. Room under 70% CLTV is 15% of value. If your business debts total less than that room, equity is not the problem, and coverage becomes the deciding test. If they total more, equity binds, and you either pay off part of the stack or look at a second property.
Which Business Debts Can the Line Pay Off?
The proceeds must retire business obligations. Personal credit cards and household debt are generally outside that purpose. Most lenders ask for a use-of-proceeds statement, and the exact wording varies by lender, so confirm it on the file.
| Business debt | Fit | Watch-out |
|---|---|---|
| Business credit cards | Strong | Pay directly; close or limit the cards |
| Business lines of credit | Strong | Confirm the line is closed, not just zeroed |
| Equipment loans | Good | Check payoff terms and lien release |
| Hard-money or bridge debt | Good | Get an exact payoff letter |
| Merchant cash advances | Case by case | Payoff may differ from the stated balance |
| SBA or term loans | Case by case | Review prepayment terms first |
| Personal credit cards | Poor | Outside the business purpose |
Payoffs are usually paid directly to the creditors. Keep the payoff letters and confirmations. Tax treatment varies; consult a qualified professional.
Why Does Business Purpose Matter?
DSCR products are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Federal rules exempt credit extended primarily for a business, commercial or agricultural purpose from many consumer-loan requirements. That is spelled out in the federal rule on business-purpose credit. The CFPB’s own page on that rule adds that the exemption holds even when a natural person guarantees or secures the credit. The ABA Banking Journal makes a practical point: the purpose of the credit is the key question. That is why the use of proceeds is documented.
The takeaway: pay business creditors with this line, and keep personal debt out of the plan.
Which Product Fits Better: DSCR HELOC, Cash-Out Refinance or Business Loan?
| Factor | DSCR HELOC | DSCR cash-out refinance | Business loan |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Not touched |
| Collateral | The rental | The rental | Varies by lender |
| Reviewed on | Rent | Rent | Business financials |
| Funding shape | Revolving, mostly drawn at closing | One lump sum | Usually one lump sum |
The line wins when you have a first mortgage worth keeping and enough equity room. A cash-out refinance makes more sense when the first mortgage is weak, the rent is too thin for a line, or you want more leverage. Standard rentals reach about 75% LTV on a DSCR cash-out through select programs, while short-term-rental collateral is capped at 70% LTV. A business loan can fit when you would rather leave your rental out of it entirely. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
A Different Product: The Personally Underwritten Investment HELOC
Do not confuse this line with the investment property HELOC that is reviewed on your personal income. That program has its own rules, including a 700 minimum score, a 70% CLTV ceiling and a $500,000 maximum. It is underwritten on you rather than on the rent, and title generally must be in your name or a revocable trust, so rentals held in an LLC usually do not fit.
Lendmire’s piece How to Use an Investment Property HELOC to Consolidate Business vs Personal Debt walks through those routes. If your rentals sit in an LLC, the DSCR version is usually the better match, subject to lender program eligibility.
The Risks Worth Taking Seriously
Moving business debt onto a rental changes the risk. Unsecured debt becomes debt secured by your property. If cash flow tightens, the rental is now exposed.
- Thin cushion. At a 70% ceiling, a modest price drop can leave you with little or no room.
- Variable rate. The rate varies and does not convert to fixed.
- Payment reset. After the 5-year interest-only draw period, a 25-year fully amortizing repayment period begins, for a 30-year maturity. The payment steps up.
- Re-accumulation. If the cards fill back up, you now owe both.
Credit and history matter too. Typical guidelines want no 30-day mortgage late in the last 12 months. They also want 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Reserves and cash to close are not required through this program, subject to underwriting.
What the File Looks Like
Lines up to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
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).
The rent, the lease, the credit report and the valuation carry the review. Eligible borrowers are US citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Frequently Asked Questions
Can the line be larger than the debt I am paying off?
Lines start at $50,000, and at least 80% of the line is drawn at closing. If your payoff total is small, the minimum can force you to draw more than you need. Size the request to the payoff plus any real business need, since the coverage test runs on the whole limit.
What if my equity or coverage falls short?
You have options. You can pay off part of the stack and leave the rest. You can use a second rental with more equity. Or you can compare a DSCR cash-out refinance that replaces the first mortgage. Each path is subject to lender guidelines and underwriting.
How long do I have to 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). Check both dates against your closing documents before applying.
Can an LLC hold the rental?
Yes, subject to lender program eligibility. The LLC can stay on title, and the members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Can I use it to pay off personal credit cards?
Generally not. The line is business-purpose credit, so proceeds go to business obligations. Confirm the use-of-proceeds wording with the lender on your file.
