The Quick Read: A DSCR HELOC lets you open a line of credit on a rental while your fixed first mortgage stays untouched. The line sits behind the first loan as a second lien. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines and underwriting.
- Lien position: the line goes in second position behind your first mortgage. It cannot be closed together with a purchase.
- Coverage: the program looks for a minimum 1.10x debt service coverage ratio (DSCR), tested on a stress payment for the whole credit limit.
- Leverage: a second lien reaches up to 70% combined loan-to-value (CLTV) on a non-owner-occupied rental, at a 720 credit score or better, through select programs.
- Paperwork: no traditional personal-income documentation, W-2s or personal income calculation. A lease, a valuation and your credit report are all documented.
- Timing rule: a rental needs two six-month clocks to run before the line is available. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
What a DSCR HELOC Actually Is
A DSCR HELOC is a revolving line of credit secured by a rental you already own. It qualifies the property’s rent instead of your paycheck. The label is informal, because lenders describe the product in different ways. What matters is the structure underneath.
When you keep a fixed first mortgage, the line is a standalone second lien. Your first loan keeps its balance, its term and its payment. The new line sits behind it. It is never a third lien, never a line on your own home, and never part of a purchase closing.
The borrower on the line does not have to be the borrower on the first mortgage. The rental can be vested in your LLC, subject to program terms. The LLC’s members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Most big banks will not touch this. Bank lines on rentals are scarce, and they often want the property in your personal name, a complaint that comes up often in BiggerPockets investor discussions. Some also underwrite on personal income. That gap is why rent-qualified second liens exist through non-QM channels. For the full picture of how this fits alongside other investor loans, Lendmire’s complete DSCR loans guide covers the basics.
Requirements at a Glance
Here is the short list a lender checks, as ranges across the wholesale lending channel Lendmire works through. Every figure is subject to underwriting and is a ceiling or floor, never an offer.
| Requirement | What the lender checks | Program range |
|---|---|---|
| Coverage | Rent against stress payment | 1.10x minimum |
| Leverage (second lien) | First balance plus new line, over value | Up to 70% CLTV |
| Credit | Lender’s own credit report | 720 minimum |
| Line size | Total credit limit | $50,000 to $500,000 |
| Mortgage history | Lates and credit events | No 30-day late in 12 months |
| Credit events | Time since bankruptcy, foreclosure, short sale | 48 months |
| Reserves | Cash held after closing | None required |
| Exposure | Loans with this program per borrower | 5 loans or $2,500,000 |
A lease in place is required. A two-to-four-unit property can have at most one vacant unit. The program serves US citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
How the Coverage Test Works With a Fixed First Mortgage
DSCR is monthly rent divided by the monthly payment the lender uses to qualify the loan. Here that payment is a stress payment. The lender assumes a fully amortizing payment on the entire credit limit, at a higher assumed rate than the line starts with. Taxes and insurance are not part of that qualifying payment.
Two details surprise people.
First, the test runs on the full limit, not just the amount you draw. A $300,000 line you plan to draw at only half is still tested as if the whole thing were borrowed. Because the program also requires at least 80% of the line to be drawn at closing, the full-limit test and your real balance stay close.
Second, rent is not simply the lease number. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser’s market rent comes from Form 1007, the single-family rent schedule.
Where does your first mortgage payment fit? Practice varies by lender, and the program does not spell out a single formula for second liens. Confirm on the file how the lender treats the first-mortgage payment, and expect that the lender’s own coverage calculation governs. Plan for the safe case. Assume the rental has to carry both loans.
Picture a rental whose rent clears the first mortgage with room to spare, at a coverage around 1.4x. Add a second lien sized to the full limit and the combined picture can drop toward 1.1x or below. The first loan passing on its own tells you little about the second. The line adds a payment against the same rent.
How Much Line Can Your Equity Support?
Sizing takes two steps. Multiply the property’s value by the program’s CLTV cap. Then subtract your first mortgage balance. What is left is the most the line can be.
Run it as percentages. Say your first mortgage is 55% of the property’s value. With a 70% CLTV cap, that leaves 15% of value for the line. A lower credit score can remove the second-lien option altogether, because there is no second-lien tier below 720.
Two adjustments can shrink the number. A declining-market flag on the property lowers the ceiling by 5 points. Whatever room is left must also pass the coverage test above, and the smaller of the two limits wins.
Equity room is tested on the lender’s valuation, not on your purchase price or a Zillow figure. Sizing off the wrong value is a common mistake, and it comes up again below.
Does Your First Mortgage Allow a Second Lien?
Read two documents before you apply: the note and the deed of trust (or mortgage) on your first loan. Look for a clause that bars additional liens, and for covenants that limit further borrowing against the property. Most ordinary fixed first mortgages do not stop a junior lien, but you should check rather than assume.
Why it matters: if you refinance the first mortgage later, the second must be paid off or subordinated first. That is a real tradeoff of keeping a low first loan and adding a line behind it. If you may refinance the first soon, plan for that step now.
A first-lien line exists only on a rental with no mortgage at all. If you have a first mortgage, the second lien is your path.
How Long Must You Own the Rental?
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).
That means a fresh purchase cannot be paired with a line at closing. The line is secured by a property you already own. It supplies cash. A separate purchase loan buys the next property.
What the File Looks Like
You bring a lease, a current first-mortgage statement, evidence of title or vesting, and hazard insurance that covers both liens. Flood coverage is added where required. The lender also pulls your credit report, and that report sets your tier.
The valuation depends on line size:
- Lines up to $400,000: an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal.
- Lines above $400,000: a full interior appraisal on Form 1004, 1073 or 1025.
Appraisal waivers are not accepted. Title work scales the same way. Smaller second liens use an owner-and-encumbrance report. Second liens above $400,000 need a full title policy.
Eligible property types are single-family homes, PUDs, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. The leverage tiers above apply to every property type.
Several property types sit outside this lane:
- Rural-designated property, row homes and condotels
- Commercial, agricultural and mixed-use property, and hobby farms
- Leaseholds, land trusts and age-restricted communities
- Modular and log homes, land contracts, and properties with a solar lien
- Any property listed for sale in the prior 2 months
Where the General Rule Breaks
You have no first mortgage. A free-and-clear rental can take a standalone first-lien line instead. Leverage is written as loan-to-value (LTV) and runs up to 75% LTV at a 740 score or better, and 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000 (to $1,000,000) are capped at 65% LTV at 720 or better. The first-lien credit floor is 700. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
You want to buy with it. Not possible. The line never closes with a purchase and is secured by a property you already own.
The rent is thin. A smaller line, or a different structure such as a DSCR cash-out refinance, may fit better. A refinance reprices the whole balance and replaces the first mortgage. A second lien leaves the first alone and adds a payment. Compare combined coverage under both before you pick.
The property is a short-term rental. The program requires a lease in place, and a lender reviews short-term income under its own guidelines. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Your credit sits between 700 and 719 and you have a first mortgage. The second lien floor is 720. That gap is the usual obstacle, and it is a credit-tier issue, not a lien-position one.
You hold the property in an LLC. Vesting in your LLC is allowed on investment property, subject to program terms. Many bank lines require personal or trust title, so check eligibility before you move any property into an entity.
You are thinking of using your primary home’s line. Many investors do tap a primary-home line to fund a rental. That is a different, owner-occupied product. The DSCR line is never offered on an owner-occupied home.
Fixed First, Variable Second: What That Means for Your Payment
Your first mortgage stays fixed. The line does not. The DSCR HELOC carries a variable rate, so the draw-period payment can move.
Here is how the line works in this program. The draw period is 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, and the loan matures at 30 years. 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.
The CFPB explains that a home equity line is an open-end credit you can borrow against repeatedly, and that payments are often significantly higher once the draw period ends. Experian notes that some HELOCs carry a balloon payment at the end of the draw period. Read the lender’s HELOC disclosures for exactly how this line behaves. The rate and the pricing terms come with the lender’s disclosures.
The practical point is simple. Interest-only helps early cash flow. The step into full amortization is where thin coverage gets exposed. Judge the deal on the repayment-period payment, not just the draw-period payment.
| Structure | First mortgage | What you add |
|---|---|---|
| DSCR HELOC (second lien) | Stays in place | A variable line behind it |
| Closed-end second | Stays in place | A lump sum with fixed payments from day one |
| DSCR cash-out refinance | Replaced | A new first loan on the whole balance |
A closed-end second hits your coverage immediately because it amortizes from the start. A line may begin interest-only. Product labels blur here, so confirm which structure you are being offered.
Mistakes That Sink These Files
Across Lendmire’s wholesale network, the same few problems recur on second-lien files:
- Assuming the first mortgage’s coverage carries over. The second adds a payment, and combined coverage can fall below the minimum even when the first passes alone.
- Skipping the first note. A lien restriction or covenant discovered late can stop the file.
- Sizing off the wrong value. Equity room is set by the lender’s valuation, not your purchase price.
- Planning to draw only a small part. The program requires most of the line drawn at closing. This is a lump of capital, not a standby card.
- Forgetting the repayment step. The payment rises when the draw period ends. Build that into your plan.
- Moving the property into an LLC first. Do it only after confirming the lender accepts entity vesting.
- Counting the clock wrong. Both six-month clocks have to be satisfied.
A word on credit: DSCR does not mean your personal profile is ignored. A 720 score is the second-lien floor, and the lender’s own report sets your tier.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rental income divided by the monthly payment the lender uses to qualify the loan.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Second lien: a loan recorded behind your first mortgage, meaning the first mortgage gets paid first if the property is sold or foreclosed.
Draw period: the stretch when you can borrow from the line and pay only interest on what you drew.
Repayment period: the stretch after the draw period when you repay principal and interest and can no longer borrow.
Seasoning: the waiting time a lender requires after you buy or refinance before a new loan is allowed.
Frequently Asked Questions
Does my existing mortgage count in the coverage ratio?
The program tests rent against a stress payment on the full line, and taxes and insurance are not part of that payment. How the first-mortgage payment joins the second-lien test is not spelled out in the program, so confirm on the file how the lender treats it. Plan as if the rental must carry both. The lender’s own calculation governs.
Is the ratio tested on the full limit or only what I draw?
The full limit. The stress payment is built on the entire credit limit, and at least 80% of the line is drawn at closing anyway. A smaller line is the cleanest way to improve coverage.
How soon after I buy or refinance can I apply?
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 an LLC hold title?
Yes, subject to program terms. The 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 do not have to match the borrowers on your first mortgage.
What if I do not qualify?
Look at the three levers: coverage, CLTV and credit tier. A smaller line can fix coverage and leverage. A score below 720 rules out the second-lien tier. A DSCR cash-out refinance, which replaces the first mortgage, may be the alternative if your first loan has room to reprice.
