The Quick Read: It depends on the lowest of three limits: the combined leverage cap (70% CLTV on a second-lien line behind your first mortgage on a rental, 65% to 75% LTV on a first-lien line on a rental with no mortgage), the line-size cap of $500,000 for most files, and the rent coverage test of 1.10x run on the full credit limit. These are ceilings, not offers, and every file is underwritten individually, subject to lender guidelines.
- Second lien: up to 70% combined loan-to-value (CLTV) at a 720 score or better, on lines from $50,000 to $500,000.
- First lien on a rental with no mortgage: up to 75% loan-to-value (LTV) at 740 or better, or 70% from 700 to 739, on lines to $500,000.
- Larger first-lien lines: above $500,000 and up to $1,000,000, the ceiling drops to 65% LTV at 720 or better.
- Rent coverage: gross rent must cover a stress payment on the entire line at 1.10x, whether or not you draw all of it.
- Cash-out refinance: a different structure that replaces your first mortgage, so its ceiling and test are set separately. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
What Is a DSCR HELOC, and How Is It Different From a Cash-Out?
A DSCR HELOC is a revolving line of credit secured by a rental you keep. DSCR stands for debt service coverage ratio. It measures whether the rent covers the payment. The line 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 debt-to-income calculation.
The line is written one of two ways. It is a standalone second lien behind the first mortgage you keep. Or it is a standalone first lien on a rental with no mortgage. It is never closed together with a purchase. It is never a third lien. It is never a line on your own home.
A DSCR cash-out refinance works differently. It pays off your current first mortgage and any junior liens, then hands you the difference. You get a new loan on new terms. The line leaves your first mortgage alone and adds a lien on top.
That difference decides most sizing questions. If your first mortgage is worth keeping, the line preserves it. If you want one new loan and a lump sum, cash-out may fit better.
Key Terms Defined
- DSCR: gross monthly rent divided by the qualifying payment on the loan.
- LTV: the loan balance divided by the property’s value, used when there is one loan on the property.
- CLTV: combined loan-to-value, meaning the first mortgage balance plus the new line, divided by value.
- Second lien: a loan that sits behind your first mortgage in repayment priority.
- Draw period: the stretch when you can borrow from the line and pay interest only on what you drew.
- Stress payment: the payment the lender tests on the full credit limit, fully amortizing, at the start rate plus 2 percentage points.
How Is the Maximum Calculated?
The formula is simple. Your usable line is the leverage cap times the property’s value, minus every loan already on the property. Then the other two limits can trim that number.
Take a second-lien line first. The cap is 70% CLTV at a 720 score or better. Say your first mortgage equals 50% of the property’s value. You have 20% of value to work with. Say it equals 60%, and you have 10% of value. Say it already sits at 70% or higher, and a second lien has no room at all.
Now a first-lien line on a rental with no mortgage. At 740 or better, the cap is 75% LTV, so 25% of value stays untouched. From 700 to 739, the cap is 70% LTV. Above $500,000, and up to $1,000,000, the cap falls to 65% LTV at 720 or better. Always name that 65% ceiling when you size a larger first-lien line. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
| Position | Credit score | Leverage ceiling | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien, no mortgage | 740 or better | 75% LTV | Up to $500,000 |
| First lien, no mortgage | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
These are ceilings and floors on select programs, subject to underwriting. A declining-market flag on the property lowers the ceiling by 5 points. There is no second-lien tier below 720. A borrower who keeps a first mortgage can only take a second lien, so a 700 to 719 score with a mortgage in place does not reach this product.
Which Limit Hits First?
Equity is rarely the only constraint. Three limits stack, and the lowest one sets your number.
The leverage cap. This is the math above. A bank HELOC works the same way in principle. The CFPB’s HELOC brochure describes a HELOC limit as typically a percentage of your equity. The DSCR version simply uses its own percentages and counts the first mortgage inside them.
The line-size cap. Second liens run from $50,000 to $500,000. A large, low-leverage property hits $500,000 before it hits the percentage cap. On a small property, the minimum matters from the other side: if the room under the cap is too thin to support a $50,000 line, there is no product to write.
The coverage test. This one surprises people. The lender tests gross rent against a stress payment on the entire credit limit, not on the balance you draw. A bigger line means a bigger test payment and a lower coverage number. So the rent itself caps the line.
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 may have at most one vacant unit. The stress payment covers principal and interest only. Taxes and insurance are not part of it. On a second lien, confirm on the file how the lender treats the first-mortgage payment, because the lender’s own coverage calculation governs.
Thin coverage is usually fixable by asking for a smaller line. A smaller limit shrinks the stress payment and lifts the ratio.
How the Draw Rules Change What You Actually Get
A DSCR HELOC pays out differently from a lump-sum cash-out. 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 comes out at closing. Later draws must be at least $5,000 each.
So this is not a standby account sitting mostly unused. Most of the money moves on day one, and you can tap the remainder later.
The structure after that is built for a long hold:
- A 5-year draw period, interest-only on the drawn balance.
- A 25-year fully amortizing repayment period after that.
- A 30-year maturity.
- A variable rate, with the pricing terms spelled out in the lender’s disclosures.
Interest-only payments during the draw period are lighter than the stress payment the lender tested. That helps cash flow in the early years. It also means the payment steps up when repayment begins, so plan for that shift.
What Lowers Your Number
Several things shrink the line or take it off the table. Check these before you count on a figure.
- 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).
- Valuation. Lines to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. A low value cuts the room under every cap.
- Property type. Single-family, PUD, townhome, two-to-four units, condominiums and lots to 10 acres can qualify. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use are outside this lane. So is a property listed for sale in the prior 2 months, or one with a solar lien.
- Credit history. There can be no 30-day late on a mortgage in the last 12 months. Bankruptcy, foreclosure, short sale or deed-in-lieu needs 48 months behind it.
- Exposure. The program allows at most 5 loans or $2,500,000 per borrower.
- Borrower status. US citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
No reserves are required on this program. Hazard insurance must cover both liens, with flood coverage where required.
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. That is a real advantage over many bank lines. Most bank-style investment HELOCs read your personal income and debt-to-income ratio, which is a different qualification path.
Does a DSCR HELOC or a Cash-Out Give You More Cash?
At the same equity, the answer turns on your first mortgage and your rent. The cash-out program sets its own ceiling, so treat any figure you see for it as that program’s rule, not the line’s. Here is how the two structures compare.
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| Existing first mortgage | Stays in place | Paid off |
| Lien position | Second lien, or first on a rental with no mortgage | New first lien |
| Coverage test | Stress payment on the full limit | Payment on the new loan |
| Cash timing | At least 80% at closing, later draws of $5,000 or more | One lump sum at closing |
| Leverage ceiling | 70% CLTV (second), up to 75% LTV (first) | Set by the cash-out program |
A cash-out resets the whole balance under new terms. Payoffs, costs and any prepayment charge come out of proceeds, so net cash is smaller than the gross number. The line avoids touching the first mortgage. If that mortgage has terms you like, that matters. If it does not, one new loan can be cleaner.
Thin coverage is also easier to repair on a cash-out, because you can reduce the new loan amount. On the line, you reduce the limit.
Common Mistakes When Sizing the Line
Assuming you can pull all your equity. Every program caps the new total at a share of value, so some equity always stays.
Assuming a higher score buys more leverage everywhere. On this program, the second-lien tier is a single 70% CLTV cell at 720. On a first lien, the score does move the ceiling between 70% and 75%.
Confusing passing the test with healthy cash flow. Clearing 1.10x means the rent covers the stress payment. It does not mean the property cash flows after vacancy, repairs, taxes and insurance. Run your own numbers before you draw.
Treating the line as permanent standby capital. A lender can freeze or reduce a line. The FTC’s HELOC page says a lender may do that if the home’s value declines significantly or if it reasonably believes you cannot pay because of a material change in your finances. That guidance is written for consumer lines. A business-purpose line follows its own loan documents, so read the freeze terms in yours.
Forgetting what the money is for. The line only creates cash. If you plan to use it as down payment on the next rental, that purchase is a separate financing decision.
What Should You Do Before You Ask for a Number?
Gather four facts. First, the property’s likely value and the balance on any first mortgage. Second, the lease and the rent. Third, your credit score and mortgage history. Fourth, how long you have held title.
Then work backward. Multiply value by the cap that fits your lien position and score. Subtract the first mortgage. Check that the result clears the $50,000 floor. Last, ask whether the rent supports a stress payment on that full amount at 1.10x. If not, shrink the line until it does.
If the numbers still do not work, a cash-out refinance may fit better. The complete DSCR loans guide lays out the wider set of rent-qualified options.
Frequently Asked Questions
Can you get a HELOC on an investment property at all?
Yes, but options are limited. Many banks write them only on a personal-income basis. A DSCR HELOC is reviewed on the rental’s income instead and is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Eligibility depends on the property, the equity, credit and lender guidelines.
What is the most I can borrow on a second-lien DSCR HELOC?
The ceiling is 70% CLTV at a 720 score or better, with lines from $50,000 to $500,000. CLTV counts your first mortgage plus the new line. The coverage test or the line cap can bring the figure lower, subject to 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).
Does the lender test the amount I draw or the whole line?
The whole line. The coverage test uses a stress payment on the entire credit limit, even though at least 80% is drawn at closing. That is why a smaller limit can raise your coverage ratio.
Can I hold the property in an LLC?
Often yes, subject to program terms. The LLC can stay on title, the members sign as guarantors, and the property must be a non-owner-occupied one-to-four-unit rental. The line is never offered on your own home or a second home.
