The Quick Read: It depends on three limits: the equity left under a 70% combined loan-to-value ceiling on an investment property after your first mortgage, the $500,000 cap on a second-lien line, and what the rent can carry when tested on the full credit limit. Whichever limit is smallest sets your line, and at least 80% of that line is funded at closing. All figures are typical ceilings through select programs, subject to underwriting.
- Equity sets the ceiling. On a second lien, the first mortgage plus the new line cannot exceed 70% of the property’s value, at a 720 credit score or better.
- Line size has a floor and a cap. Lines start at $50,000 and reach $500,000 on a second lien.
- Rent tests the whole limit. Coverage must reach 1.10x on a stress payment for the entire line, not just the drawn part.
- The closing draw is large. At least 80% of the line is drawn at closing, and never less than $50,000.
- Later draws are small and optional. Each later draw is at least $5,000. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment. A result of 1.10x means the rent is 110% of that payment.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value. We write it as CLTV for second liens.
LTV (loan-to-value): the loan divided by value when there is only one loan. We use it for a first-lien line on a rental with no mortgage.
Closing draw: the money funded the day the line is set up. On this program it is at least 80% of the line.
Draw period: the stretch when you can take money out and pay interest only on what you drew. Here it is 5 years.
Stress payment: a fully amortizing payment on the full credit limit at the start rate plus 2 percentage points. The lender uses it to test coverage. It is not what you will necessarily pay.
What Kind of Line Is This?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied one-to-four-unit rental, qualified on the rent instead of your personal income. It is written as a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien on a rental with no mortgage. It is never closed with a purchase, never a third lien, and never placed on your own home.
Your LLC can stay on title, subject to program terms. The members sign as guarantors. You provide no traditional personal-income documentation, W-2s or pay stubs, and the lender calculates no debt-to-income ratio. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Many investors keep a low-cost first mortgage in place and tap equity behind it.
A standard bank HELOC on a rental is a different product. NerdWallet notes that a HELOC on an investment property means fewer lenders and less borrowing than against a primary home. That version is usually underwritten on your personal income. The DSCR version tests the rental itself.
The Three Limits That Set Your Line
Your maximum line is the smallest of three numbers. Think of it as three gates in a row.
Gate one is equity. Take the program’s maximum combined leverage times the property value. Subtract the first mortgage balance. What is left is the most the line can be.
Gate two is the line cap. On a second lien the line runs from $50,000 to $500,000. On a first lien the lines run to $1,000,000, but the leverage drops on the larger ones (more on that below).
Gate three is rent. The lender tests coverage on the entire credit limit, so a property with plenty of equity can still be held back by thin rent.
After those gates, 80% of the approved line funds at closing. Everything else in the article hangs off the three gates and that closing draw.
Step-by-Step: Sizing the Line
1. Start with value. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal.
2. Apply the leverage ceiling. A second lien reaches 70% CLTV at a 720 score or better. A first lien on a rental with no mortgage reaches 75% LTV at 740 or better, or 70% LTV at 700 to 739. First-lien lines above $500,000 drop to 65% LTV at 720 or better. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
3. Subtract the first mortgage. Only the balance you owe comes off. Nothing else does.
4. Check the cap and the floor. If the room is below $50,000, there is no line to write.
5. Run the rent test on the full line. If coverage falls short of 1.10x, the line must shrink or the deal does not work.
6. Take 80%. That is your minimum closing draw. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The method is the same one any home equity line uses. The CFPB’s HELOC booklet walks through it with a generic example: a $100,000 home times 75%, less a $40,000 mortgage, leaves a $35,000 potential line. That example uses the booklet’s own percentage, not this program’s. Swap in 70% CLTV and the same steps apply.
Here is the second-lien math in percentages of value, so it works on any property:
- A rental with a first mortgage at 50% of value has 20% of value in room under a 70% CLTV ceiling. The line is at most 20% of value, and at least 80% of it, or 16% of value, funds at closing.
- A rental with a first mortgage at 30% of value has 40% of value in room. The $500,000 cap may bind before equity does on a high-value property.
- A rental with a first mortgage at 65% of value has only 5% of value in room. Unless the property is very valuable, that falls under the $50,000 minimum.
How the Maximum Shrinks as the First Mortgage Grows
This table shows the equity ceiling on a second lien at 70% CLTV. It comes before the $500,000 cap, the $50,000 floor and the rent test, which can all lower it further.
| First mortgage (% of value) | Room under 70% CLTV | Closing draw (80% of room) |
|---|---|---|
| 20% | 50% of value | 40% of value |
| 40% | 30% of value | 24% of value |
| 50% | 20% of value | 16% of value |
| 60% | 10% of value | 8% of value |
| 65% | 5% of value | 4% of value |
Every 10 points of first mortgage you carry cost you 10 points of line room. That is why a rental you have paid down for years can support a much larger line than one you bought with a high-leverage loan.
A rental with no mortgage works differently. The room is the whole leverage ceiling: 75% of value at 740 or better, or 70% at 700 to 739, on lines to $500,000. Above $500,000 the ceiling is 65% of value at 720 or better, up to $1,000,000.
The Rent Test Runs on the Full Limit
Coverage is gross monthly rent divided by the qualifying payment. That payment is principal and interest on the whole credit limit, fully amortizing, at the start rate plus 2 percentage points. Taxes and insurance are not part of it. The minimum is 1.10x.
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.
Because the test uses the full limit, a smaller requested line helps coverage. Asking for less than the equity allows is a legitimate way to clear 1.10x. 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 arithmetic here is only illustrative.
Say a duplex has a lot of equity but modest rent. The equity ceiling may allow a large line, but the rent test may only support a smaller one. In that case, rent is your binding limit, and no amount of equity changes it.
What an 80% Closing Draw Means for You
At least 80% of the line is drawn the day it closes, and the closing draw is never under $50,000. On a $50,000 line, you draw the whole thing at closing. The CFPB notes that some home equity plans require an initial draw or minimum draws. This program has both: a required closing draw and a minimum size for later draws.
The practical effect is simple. You owe interest on most of the line from the start, since interest-only applies to the drawn balance. This is closer to a large loan with a small undrawn remainder than to an emergency reserve. It suits a planned capital need, such as a down payment on the next rental, a renovation, or paying off a higher-cost debt.
It does not suit someone who wants a large untouched cushion. If you size the line bigger than the money you need, you borrow idle cash and pay interest on it. Size the line to the project, not to the maximum.
After closing, later draws are at least $5,000 each. The draw period lasts 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, and the rate and pricing terms come with the lender’s disclosures. When the draw period ends, the payment steps up because you begin paying principal. Plan for that day before you borrow.
If you plan to use the money to buy another property, note that the line must exist before you go under contract. A purchase lender typically wants the draw records and the funds traced, and some want the money seasoned.
Tax treatment can depend on how the funds are used and how the property is held. Keep clear records and speak with a qualified tax professional before relying on any deduction.
What the File Needs
The rent, the lease, the credit report and the valuation carry the review. The property file also includes the first-mortgage statement, entity documents, insurance and title.
- Credit: 720 minimum on a second lien, 700 on a first lien. No 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Reserves and cash to close: none required.
- Exposure: at most 5 loans or $2,500,000 per borrower with the program.
- Borrowers: US citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- 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: single-family, PUD, townhome, two-to-four units, and condominiums are eligible. Rural property, condotels, row homes, leaseholds, land trusts, and a property listed for sale in the prior 2 months are not.
The line is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower. For the full credit, rent and document picture, see Lendmire’s breakdown of the requirements for this line in how to qualify for a DSCR HELOC that draws 80% of the line.
When This Is the Wrong Structure
The line is the wrong fit when the room under the ceiling is thin, when you need money you will not draw, or when you would rather replace the first mortgage anyway. Compare the options by structure.
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank HELOC on personal income |
|---|---|---|---|
| First mortgage | Stays in place | Replaced by a larger loan | Stays in place |
| Qualified on | Rent | Rent | Your income and debts |
| Money at closing | At least 80% of line | One lump sum | Set by that lender |
| LLC on title | Allowed, subject to terms | Per program terms | Often excluded |
If your first mortgage carries a low cost you want to protect, the line keeps it. If your equity is large and you want one clean loan, a cash-out refinance may fit better.
Sizing Mistakes to Avoid
- Counting only the drawn amount toward leverage or rent. Both tests use the full line.
- Forgetting the first mortgage. Combined leverage includes it, so the room is smaller than value times 70%.
- Ignoring the $50,000 floor. A thin-equity rental may not leave enough room for any line.
- Asking for the maximum. A larger line means a larger forced closing draw and a harder rent test.
- Skipping the step-up. The payment rises when the draw period ends, so check your rent against that future payment.
- Assuming any HELOC on a rental is a DSCR HELOC. Many are underwritten on personal income and may not allow LLC title.

Frequently Asked Questions
Can I draw less than 80% at closing?
No. At least 80% of the line is funded at closing, and the closing draw is never under $50,000. On the smallest lines, that means the whole line is drawn. Plan the line around money you will use soon, and size it so the closing draw matches your need.
Does rent have to cover the drawn balance or the whole line?
It has to cover the whole line. Coverage is tested at 1.10x on a stress payment for the entire credit limit, not just the drawn balance. A property with strong equity can still be limited by rent, and a smaller requested line can improve coverage. The lender’s own calculation governs.
How soon after buying a rental can I open one of these lines?
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 clocks must be met, subject to underwriting.
Can my LLC be the borrower?
Yes – the line can vest in the owner’s LLC (investment property only), with the members signing as guarantors. The LLC can stay on title, subject to program terms. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
What if I have no mortgage on the rental?
Then a first-lien line is possible. Leverage reaches 75% LTV at 740 or better, or 70% LTV at 700 to 739, on lines to $500,000. Lines above $500,000 run to $1,000,000 at 65% LTV and a 720 score or better. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
