The Quick Read: Yes, through select programs, a DSCR HELOC can sit as a standalone second lien behind the first mortgage you keep, and the rental’s rent, not your personal income, qualifies the line, subject to underwriting. The first mortgage is never touched, replaced or reset. The coverage test and the combined leverage cap decide how much room you actually have.
- The line is written as a second lien behind your existing mortgage, or as a first lien on a paid-off rental.
- It is reviewed on a minimum 1.10x coverage ratio, tested on a stress payment over the whole line.
- Second-lien combined leverage tops out at 70% CLTV, with a 720 credit score or better.
- Lines run from $50,000 to $500,000 on a second lien, subject to underwriting.
- Offered in 15 states, and an LLC can hold title. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Most investors who ask this question already hold a first mortgage they like. Keeping it is the whole point. This article walks through how the structure works, where it stops working, and when a different tool is the better call.
What Is a DSCR HELOC When the First Mortgage Stays?
A DSCR HELOC is a revolving line of credit secured by a non-owner-occupied one-to-four-unit rental. When you keep your mortgage, the line is written as a standalone second lien behind it. It is never closed alongside a purchase, never a third lien, and never placed on your own home.
Two ideas sit inside that label. “DSCR” means the property’s rent qualifies the line instead of your tax returns, W-2s or pay stubs. “HELOC” means a draw-as-needed line instead of a lump sum. The CFPB explains that a loan behind an existing mortgage is a second mortgage you pay on top of the first, and that a HELOC revolves while a home equity loan pays out a lump sum. That framing applies here, with one difference: the file runs on the rental’s income.
Qualification, in plain words, rests primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, valuation and the property itself still matter. This is documented lending, not a shortcut.
Business-purpose investor loans like this one are reviewed differently from a standard owner-occupied mortgage. That is why a bank’s homeowner HELOC desk and this product feel like different worlds.
How Does the Rent Qualify the Line?
The line needs a minimum 1.10x coverage ratio. That is gross monthly rent divided by a qualifying payment, and the qualifying payment is deliberately harsh. It assumes the entire credit limit is fully amortizing at the start rate plus 2 percentage points. A stress test, in other words. You are not tested on what you will draw today. You are tested on the whole line.
Rent counts as the lesser of the appraiser’s market rent (the Form 1007 rent schedule) or the lease in place. A lease is required. A lease running above market counts only with three months of receipts. On a two-to-four-unit property, at most one unit can sit vacant.
Here is the catch for investors keeping a mortgage. Whether the first mortgage payment joins the qualifying payment on a second lien is not something the program publishes, so no one can honestly hand you a formula. The lender’s own coverage calculation governs. What you can do is protect yourself: if your rent clears the stress test on the full line with room to spare, you are in safer territory regardless of how the first payment is treated.
Think of a rental whose rent covers the stress payment at roughly 1.3x. That cushion tolerates a vacancy or two better than a file sitting at 1.10x. The thinner the margin, the less a variable-rate line forgives.
What Leverage Does a Second Lien Allow?
On a second lien behind your mortgage, combined loan-to-value (CLTV) reaches up to 70%, with a 720 credit score or better, subject to underwriting. CLTV means your first mortgage balance plus the new line, divided by the property’s value. Lines run from $50,000 up to $500,000. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Do the math on a paper example. Say a rental is worth $400,000 and the first mortgage balance sits at 50% of value. A 70% CLTV ceiling leaves room for a line equal to 20% of value, which works out to a line near the $80,000 mark. You can see how the first balance eats room before the new line starts. A low balance on an older mortgage helps. A fresh, high-balance first leaves little.
There is no second-lien tier below 720. At 740 or better and from 720 to 739, the ceiling is the same 70% CLTV. A first lien on a paid-off rental is a different case, with up to 75% LTV at 740 or better, and 70% from 700 to 739, on lines to $500,000. Larger first-lien lines, to $1,000,000, carry a 65% LTV ceiling. These are ceilings, not offers. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Other adjustments apply. A declining-market flag lowers the ceiling 5 points. Philadelphia lines sit 10 points lower. Condominium limits are set separately, though the tiers above already sit beneath those.
Draws, Repayment and the Variable-Rate Reality
The structure is built for investors who will use most of the line, not hold it as a standby. At least 80% of the line is drawn at closing, never less than $50,000, and later draws are at least $5,000 each. The draw period runs 5 years interest-only on the drawn balance. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
That last word deserves respect. A variable line on top of a fixed first mortgage means your total carry can move. The rate and the pricing terms come with the lender’s disclosures, and a home equity line is open-end credit with its own disclosure package. Read it before you sign.
Two risks show up on most stress tests. First, the end of the interest-only period. When repayment starts, the payment steps up because principal begins amortizing. Second, the stacked payments. A low-rate first plus a higher-cost second can cost more over the long run than a single refinance, a point investors on BiggerPockets raise when they suggest refinancing later once the investment cash-flows. The counterpoint is just as real, and it is the reason this article exists: you pay the higher cost only on the smaller second balance, not on the whole loan.
HELOC vs Closed-End Second vs Cash-Out Refinance
The right tool depends on whether the first mortgage is worth keeping, how much cash you need, and whether you want revolving access.
| Factor | DSCR HELOC (second lien) | Closed-end second | DSCR cash-out refinance |
|---|---|---|---|
| First mortgage | Stays in place | Stays in place | Replaced |
| Funds arrive | Line, then draws | One lump sum | One lump sum |
| Payment style | Interest-only, then amortizing | Fully amortizing | Fully amortizing |
| Best when | Your first is worth keeping | You want fixed structure | Your first is not worth keeping |
The closed-end and refinance columns describe those product types in general; the HELOC column reflects this program, subject to underwriting.
Choose the line when you are carrying a first mortgage you would not want to replace and you plan to use most of the funds. Choose a cash-out refinance when your first mortgage is not worth protecting, when you need more room than a 70% CLTV ceiling gives, or when you want the simplicity of one loan.
Across a wholesale network, the files that run into trouble are not usually the ones with thin credit. They are the ones where the borrower quoted a loan amount from memory of what the property was “worth” and found the first balance, plus the line, pushed past the CLTV ceiling once an automated valuation came in. Running the combined number against a conservative value before applying avoids the surprise.
The Gates: Title, First Lender, Seasoning and Property Type
Four gates decide whether the structure is even available.
Title and entity. Vesting in your LLC is allowed on this program, subject to program terms. Members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not be the borrowers on the first mortgage. Bank products on rentals often require an LLC and may be commercial lines rather than true HELOCs, as a BiggerPockets podcast guest described, so title structure is worth settling early.
Your first mortgage. Read your note and security instrument for any language about junior liens before applying. A first lender’s documents can matter, and the title search will surface the question either way.
Seasoning. A rental bought or refinanced inside the last 6 months is not eligible, counted note date to note date, and 6 months of ownership are required. This is not a year of seasoning. It is six months.
Property type. Single-family, PUD, townhome, two-to-four units, condominiums and lots to 10 acres are eligible. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, mixed-use, a property listed for sale in the prior 2 months, and a property with a solar lien are outside it.
Credit, Borrowers and the File
Credit minimums are 720 on a second lien and 700 on a first lien, based on the lender’s own report. There should be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
Eligible borrowers are U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible here.
Valuation depends on line 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. Recently rehabbed properties deserve extra thought: an automated valuation can undercount value created by renovation, which is why a full appraisal may serve a rehab better. Any improvement may support a higher appraised value, depending on comps and underwriter review.
What the Bank Route Looks Like Instead
A bank or credit-union line is a different, shrinking route. The CFPB’s consumer HELOC booklet is written for homeowners and notes that renting out your home may be prohibited under a line’s terms. Treat it as background on how HELOCs work, not as the rule for an investor line.
Large retail lenders often decline lines on rentals and offer a cash-out refinance instead, which would replace your first mortgage. Some credit unions and regional banks will still write non-owner-occupied lines when credit and leverage fit, and a few allow LLC title. If you can get one, compare it against the DSCR route on qualification, entity title and leverage. Lendmire’s guide to an investment property HELOC when you keep your mortgage covers the personal-income version of this idea in more detail.
A DSCR line makes more sense when your personal profile is hard to document, when your portfolio sits in an LLC, or when a bank has already said no. For a high-W-2 owner with one rental and a willing bank, the bank route may be simpler. That is the flip point.
A Practical Path Through the Decision
1. Pull your first mortgage balance and a conservative value estimate. Compute combined balance divided by value against a 70% ceiling. 2. Confirm the property is outside the excluded list and past 6 months of ownership. 3. Check your lease and the market rent. Rent counts at the lesser of the two. 4. Stress the coverage: does rent clear 1.10x against a payment on the full line at an elevated rate? 5. Decide the exit. Plan for the payment step-up when repayment begins.
If any step fails, that is information. A property that cannot clear the stress test at your intended line size may do better with a smaller line, a closed-end second, or a refinance. Sub-1.00 coverage structures exist through select lenders in the wider DSCR network, but leverage and terms adjust, and this program’s floor is 1.10x. For a broader view of how DSCR loans work, see Lendmire’s complete DSCR loans guide.
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.

Frequently Asked Questions
Can the LLC that owns my rental hold a DSCR HELOC?
Yes, subject to program terms. The line can be vested in your LLC, and the members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The property must be an investment property, not your own home.
Does a DSCR HELOC change my existing first mortgage?
No. The first mortgage stays in place with its balance, term and payment untouched. The new line sits behind it as a second lien. A cash-out refinance, by contrast, replaces the first mortgage and resets its terms.
How soon after buying a rental can I apply?
Six months. A rental bought or refinanced inside the last 6 months is not eligible, and six months of ownership are required. Plan the timing around your purchase or refinance date.
Is a lease required?
Yes. A lease in place is required, and rent counts at the lesser of the lease or the appraiser’s market rent. A lease above market counts only with three months of receipts. A two-to-four-unit property may have at most one vacant unit.
Is this available everywhere?
No. 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.
