The Quick Read: Yes, on a second lien behind a first mortgage you keep, a DSCR HELOC reaches 70% combined loan-to-value at a 720 credit score or better, subject to underwriting, on lines from $50,000 to $500,000, but the first mortgage counts against that 70% too, so the room left is often smaller than owners expect. The rent qualifies the line, not your personal income. Think of 70% as a ceiling, not an amount you are owed.
- A second lien reaches 70% CLTV at 720 or better; the first mortgage balance plus the new line must fit under that cap.
- A paid-off rental can carry a first-lien line up to 75% loan-to-value at 740 or better, through select programs.
- The rent must cover a stress payment on the whole credit limit at 1.10x or better.
- The rental needs 6 months of ownership, and the LLC can stay on title.
- All of this is subject to underwriting. Every file is reviewed individually.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line of credit secured by a rental property, qualified on the property’s rent instead of your paycheck. DSCR stands for debt service coverage ratio. It measures whether the rent covers the payment. The label is a market nickname, so the structure matters more than the name.
The line sits in one of two positions. It is a standalone second lien behind a 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, never a third lien, and never a line on your own home.
This is a business-purpose product for non-owner-occupied one-to-four-unit rentals. Because of that, it is reviewed differently from an owner-occupied home equity line. Across the wholesale network Lendmire works with, the program qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Tax returns, W-2s, pay stubs and a personal debt-to-income ratio are not part of the review. The lease, the credit report and the valuation all are.
For the broader picture, Lendmire’s complete DSCR loans guide covers how coverage-based lending works across products.
How Does the 70% Combined Math Work?
Combined loan-to-value, or CLTV, adds every loan on the property and divides by its value. At 70% CLTV, the first mortgage plus the new line cannot exceed 70% of value. The line is only what is left after the first mortgage.
Here is the formula. Value times 70%, minus the first mortgage balance, equals the maximum line. If the first mortgage already uses 50% of value, the line can use up to 20 points. If it uses 65%, you have 5 points. If it uses 70% or more, you have nothing.
| First mortgage as % of value | Room under 70% CLTV | What it means |
|---|---|---|
| 40% | 30 points | Plenty of room |
| 55% | 15 points | Workable on a higher-value rental |
| 65% | 5 points | Rarely reaches the minimum line |
| 70% or more | None | No second-lien cell |
That table matters because of two program rules. Lines start at $50,000, and at least 80% of the line is drawn at closing. Five points of room only clears that minimum on a very high-value property. Treat the arithmetic as illustrative. The lender’s own calculation governs.
The Reverse Math: How Much Room Do You Need to Open?
Start from the line you want, then work backward. Say you want a line of about 15% of the property’s value. Your first mortgage must sit at or below 55% of value at the time of the valuation.
You get there two ways. You pay the first mortgage down, or the value rises. A lower first-mortgage balance and a higher value both widen the gap. A valuation that comes in lower than you expected shrinks it, and that is the part owners underestimate.
A declining-market flag on the property can lower the ceiling by 5 points. In Philadelphia, the ceiling runs 10 points lower. Both are under the program’s own overlays, so a 70% cap can become 65% or 60% on the same file.
Why a Recent DSCR First Mortgage Often Leaves No Room
Many investors buy with a high-leverage DSCR loan, then ask about a line later. The problem is usually arithmetic. A purchase loan written near its own leverage cap leaves little space under a 70% combined ceiling. The line has to fit in whatever remains.
Seasoning adds a second hurdle. This program does not accept a rental bought or refinanced in the last 6 months, counted note date to note date. It also requires 6 months of ownership. So a brand-new purchase waits, and by then the first mortgage may still be too large.
Owners with the most room tend to fall into three groups. Some bought years ago and have paid the balance down. Some had values rise. Some own the rental free and clear. For that last group, the first-lien structure usually fits better.
First Lien or Second Lien: Which Applies?
Leverage depends on lien position. Write second-lien figures as CLTV and first-lien figures as LTV, because they measure different things.
| Structure | Leverage ceiling | Credit | Line sizes |
|---|---|---|---|
| Second lien, behind your first mortgage | 70% CLTV | 720 or better | $50,000 to $500,000 |
| First lien, no mortgage | 75% LTV | 740 or better | To $500,000 |
| First lien, no mortgage | 70% LTV | 700 to 739 | To $500,000 |
| First lien, larger line | 65% LTV | 720 or better | $500,000 to $1,000,000 |
Below 720 there is no second-lien cell. A first lien starts at 700. All of this runs through select programs, subject to underwriting, and these are ceilings, not offers. Notice that a higher score does not raise the second-lien cap. At 720 or 740 the ceiling is the same 70%. Credit decides whether you qualify more than how much you can borrow.
Mortgage history is also reviewed. The program wants no 30-day late payment on a mortgage in the last 12 months. It wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
How Is the Line Actually Underwritten?
The rent carries the file. The lender checks that gross monthly rent divided by a qualifying payment is at least 1.10x. That qualifying payment is a fully amortizing payment on the entire credit limit, not just the amount you draw, calculated at a stress level above the start rate. So a large undrawn line still counts against coverage.
Rent is the lesser of two figures. One is the appraiser’s market rent on Form 1007. The other is the lease. A lease above market counts only with three months of receipts. A lease must be in place. On a two-to-four-unit property, at most one unit may be vacant.
Whether the first-mortgage payment joins the qualifying payment on a second lien is not something Lendmire can state as a fixed formula. Treat the lender’s coverage calculation as the final word. Run your own number both ways before applying and see how much cushion you keep.
Here is how this differs from the bank route. A bank line on an investment property is typically a personal-credit product. NerdWallet notes the pool of lenders is smaller and the borrowing limit lower than on a primary home. Those lenders see higher default risk. In this network’s DSCR HELOC, the second-lien ceiling is 70% CLTV and the first-lien ceiling is 75% LTV.
Valuation Sets the Denominator
Every ratio above divides by value, so the valuation drives the result. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report. A full interior appraisal is the alternative. Lines above $400,000 require a full interior appraisal on Form 1004, 1073 or 1025.
Appraisal waivers are not accepted. Plan for a real valuation on every file.
Say your estimate of value is 8% above what the appraiser concludes. At 70% CLTV, that gap can erase the entire line on a rental with a mid-sized first mortgage. Pull your first-mortgage balance and a conservative value before you assume any number.
Who and What Is Eligible
Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit buildings, warrantable condominiums and non-warrantable condominiums. Non-warrantable condos reach 75%, which the tiers above already sit under. Lots up to 10 acres qualify.
Several types are outside this lane. These include 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. A property listed for sale in the prior two months and one with a solar lien are also out.
Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. No reserves and no cash to close are required, and an investor may carry at most 5 loans or $2,500,000 with the program.
Vesting in your LLC is allowed on investment property, 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. The borrowers on the line do not have to match the borrowers on the first mortgage. That is a real difference from many bank lines, which in our experience tend to lend to individuals or trusts rather than entities.
The program is offered in 15 states under Lendmire’s consumer licensing: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. It is not offered in Tennessee.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
The Draw Rules and the Cash-Flow Risk
The line has a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, and the maturity is 30 years. The rate is variable. At least 80% of the line is drawn at closing. Later draws are at least $5,000 each.
The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, based on the equity in the property. That repeat access is the appeal. It is also the risk.
Because the rate is variable, your cost can move after closing. Interest-only draws on a thin-margin rental can strain cash flow. The honest test is simple. Re-run your coverage assuming the full line is drawn and the rate has moved against you. If the rental only works with room to spare, size the line smaller than the cap allows.
One reality of the leverage stack is worth stating plainly. Total leverage rises when you add a second lien. That cuts your cash-on-cash return and your cushion if values fall. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
If You Are Over the Ceiling, What Next?
Over the 70% line is common. You have options.
| Situation | Practical path |
|---|---|
| First mortgage too large | Pay it down, or wait for value to rise |
| Value came in low | Revisit once comps support more |
| Coverage under 1.10x | Draw less, or review a different structure |
| Rental recently bought | Wait until the 6-month marks are met |
| First mortgage not worth keeping | Look at a DSCR cash-out refinance instead |
A DSCR cash-out refinance replaces the first mortgage with a new loan, so it is a different product. It makes sense when your existing first mortgage is expensive to keep or the combined room is too thin. A line makes sense when the first mortgage is worth keeping and you want flexible access. Programs below 1.00 coverage are available through select lenders in the network, but leverage and terms adjust.
This is a genuine trade-off, and either path can be right. The line keeps your first mortgage intact and draws only what you need. The refinance resets everything but may release more.
Key Terms Defined
DSCR HELOC: a market label for a revolving line on a rental, qualified on the property’s rent.
Combined loan-to-value (CLTV): all liens on the property added together, divided by its value.
DSCR: gross monthly rent divided by the qualifying payment; a number above 1.00x means the rent exceeds that payment.
Second lien: a loan that sits behind a first mortgage and is repaid after it if the property is sold.
Seasoning: the waiting period after you buy or refinance before a lender will consider the property.
Frequently Asked Questions
Can I really get a DSCR HELOC at 70% combined loan-to-value?
Yes, as a second lien at a 720 credit score or better, through select programs and subject to underwriting. The cap counts your first mortgage, so the usable line equals 70% of value minus what you owe. Many owners find that figure is smaller than expected, or zero. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Does a higher credit score raise the 70% cap?
Not on the second lien. A 720 and a 740 both sit at 70% CLTV. Score is mainly an eligibility gate there. On a first lien, 740 or better reaches 75% LTV while 700 to 739 reaches 70%. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Can my LLC hold the rental?
Yes, subject to program terms. The members sign as guarantors, and any title holder who is not a borrower signs a non-borrowing owner acknowledgment. This is one reason investors with entity-titled rentals look at this product rather than a bank line.
Do I need tax returns or a debt-to-income ratio?
No. The line qualifies primarily on the rent covering the payment. You still provide a lease, a credit report and a valuation, and the lender reviews the whole file.
How soon after buying a rental can I open a line?
A rental bought or refinanced inside the last 6 months is not eligible, and the program requires 6 months of ownership. After that, the first-mortgage balance on a recent purchase usually decides whether any room remains.
