The Quick Read: Through select programs, a DSCR HELOC on a rental you already own can reach 70% combined loan-to-value on a second lien, with lines of $50,000 to $500,000, subject to underwriting. The line is sized on the rental you keep, not the one you are buying, and the rent has to clear a 1.10x coverage test on a stress payment across the whole line.
- Second lien: up to 70% CLTV at a 720 score or better, lines to $500,000.
- First lien, on a rental with no mortgage: up to 75% LTV at 740 or better, and 70% from 700 to 739, on lines to $500,000.
- First-lien lines above $500,000 (to $1,000,000) top out at 65% LTV.
- At least 80% of the line is drawn at closing, so size the line to the cash you need.
- Rent qualifies the line, not personal income, subject to lender guidelines.
The Simple Math: Value, Cap, Minus Liens
The amount you can borrow comes from subtraction. Take the property’s value, multiply by the leverage cap, then subtract every lien already recorded. The program’s line limits sit on top of that result.
The CFPB’s HELOC booklet defines equity as the home’s value minus what you owe, and notes that borrowing is limited to a percentage of that equity. The same booklet warns that a lender may reduce a line if the property’s value falls. That risk is real for any investor planning around a line.
Here is the formula in plain terms:
| Step | What you do |
|---|---|
| 1 | Establish the rental’s value |
| 2 | Multiply by the lien-position cap (CLTV for a second lien, LTV for a first) |
| 3 | Subtract the first mortgage balance, if any |
| 4 | Compare to the $500,000 or $1,000,000 line limit |
| 5 | Test the result against the 1.10x coverage requirement |
What Does a DSCR HELOC Actually Fund?
A DSCR HELOC is a revolving line secured by a rental you keep. It is a standalone second lien behind your existing first mortgage, or a standalone first lien on a rental with no mortgage. It is never a line on your own home, and it is never closed together with a purchase.
That last point surprises people. You cannot open a line against the property you are about to buy. The line comes from a rental you already own, and the cash then becomes your down payment, closing costs, or renovation budget on the new deal. A separate loan, often a DSCR purchase loan, finances the new property itself.
If you do not yet own a rental with equity, no line exists to draw on. In that case a different route fits better, covered later.
How Does the Rent Test Limit the Amount?
The rent test caps many lines before the leverage cap does. The line qualifies at a minimum 1.10x DSCR, which is gross monthly rent divided by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit at a stress rate above the start rate. Principal and interest only; 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, and a two-to-four-unit property may have at most one vacant unit.
Notice the sizing effect. Because the stress payment covers the entire line, not just the drawn amount, a larger line needs more rent behind it. A rental with plenty of equity but modest rent may qualify for less than the equity math suggests. Whether the first-mortgage payment joins the qualifying payment on a second lien is something to confirm on the file, since the lender’s coverage calculation governs.
Three Scenarios Carried to the Purchase
Run the numbers on three types of rental. These are illustrations only, and the lender’s own calculation governs.
The free-and-clear rental. Picture an investor with a paid-off rental at a 750 score. A first lien can reach 75% LTV on lines to $500,000, so the equity cap is generous. The limiting factor becomes the rent test across the full line. If rent clears 1.10x on the whole limit, the cash can cover the down payment on the next purchase with room to spare. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The moderately leveraged rental. Say you own a rental with a first mortgage and a 740 score. A second lien allows up to 70% CLTV. If the first mortgage plus the new line would exceed 70% of value, the line shrinks until it fits. Add the first mortgage balance to the line, divide by value, and keep the result at or under 70%.
The recently bought, high-leverage rental. An investor who bought at a high loan-to-value last year often has no room under a 70% CLTV cap. The equity simply is not there. Two six-month clocks also apply: 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).
Credit adds another layer. Below 720, there is no second-lien tier. A 700-to-719 borrower with a first mortgage has no second-lien cell on this lane, while a first lien needs a 700 floor and a rental with no mortgage.
Draw Rules That Shape Your Real Number
The line size and the cash you need should match closely. 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 is drawn at closing. Later draws are at least $5,000 each.
That matters for sizing. Borrowing a $500,000 line to fund a $90,000 down payment leaves you carrying idle borrowed cash. The draw period is 5 years interest-only on the drawn balance, followed by a 25-year fully amortizing repayment period and a 30-year maturity. The rate is variable.
Variable means the payment can rise while the new rental’s rent stays flat. Stress your plan with that in mind.
Does the Purchase Lender Care Where the Down Payment Came From?
Yes, it reviews the source of funds. One BiggerPockets thread notes a HELOC-funded down payment is generally permissible, though the same discussion cautions that cash flow must also cover the HELOC payment. Treat the draw as a documented, traceable transfer. Keep the line statement and the deposit trail together.
A DSCR purchase loan tests the new property’s rent against its own payment. The HELOC payment is a separate obligation your cash flow has to carry. If the new rental’s coverage comes in thin while the line is also drawn, you have two thin margins stacking. One investor describes this structure as essentially borrowing 100%, which leaves no equity cushion in the new property on day one.
That is a judgment call, not a rule. An investor with strong reserves and stable rent can carry that structure. One relying on appreciation to rescue a thin deal is taking a bigger bet than the loan math shows.
Key Terms Defined
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment.
Draw period: The 5 years when you can borrow from the line and pay interest only on the drawn balance.
Stress payment: A fully amortizing payment on the whole credit limit at a higher test rate, used only to qualify.
Seasoning: The waiting time after a purchase or refinance before the property is eligible.
What Is Outside the Program?
Several property types are not eligible on this lane: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, and properties listed for sale in the prior two months. A declining-market flag lowers the ceiling 5 points, and Philadelphia lines carry a ceiling 10 points lower.
Per-borrower exposure is capped at 5 loans or $2,500,000 with the program. Foreign nationals and ITIN borrowers are not eligible. Valuation depends on size: lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal; larger lines take a full interior appraisal. Appraisal waivers are not accepted.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, through select wholesale lenders. Lendmire is a broker arranging the line, not the lender.
When Another Route Fits Better
A DSCR HELOC suits an investor who keeps a low-leverage first mortgage and wants equity without refinancing it. Other paths can be the better call:
- DSCR cash-out refinance may fit if you would rather replace the first mortgage.
- A bank statement home equity option may fit self-employed owners who qualify on documented deposits.
- No equity yet means saving, partnering, or a different purchase structure.
Keep the whole sequence in view in the complete DSCR loans guide. The right structure depends on your equity, your first mortgage, and how thin the new rental’s coverage could run.
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
What is the most I can borrow on a DSCR HELOC?
A second lien reaches up to 70% CLTV on lines to $500,000 at a 720 score or better. A first lien on a rental with no mortgage reaches 75% LTV at 740 or better on lines to $500,000, and 65% LTV on lines above $500,000, to $1,000,000. All figures are subject to underwriting and the rent test. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Can I open a DSCR HELOC on the property I am about to buy?
No. The line must be secured by a rental you already own. You draw cash from it and use that cash toward the new purchase, which is financed separately.
Does the line count against my ability to qualify for the next loan?
The new DSCR purchase loan tests the new property’s rent against its own payment. The line’s payment is a separate obligation your cash flow must carry, and the purchase lender will review the source of the funds.
How long must I own a rental before opening a 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).
Can my LLC hold the property?
Yes, an LLC can hold title on an investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
