The Quick Read: A DSCR HELOC is tested by dividing the rental’s qualifying monthly rent by a stress payment calculated on the entire credit line, not just the amount you draw, and the result must reach 1.10x on this program, subject to underwriting. Lendmire is a broker that arranges this line through a wholesale lender in its network. It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
- The rent is the top number. The stress payment on the full line is the bottom 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 size of the line you request sets the test, so the payment is built on the full limit.
- Leverage, credit score, valuation and seasoning are separate gates that sit next to the ratio.
- Every figure here is a ceiling or floor on select programs, subject to underwriting. The lender’s own calculation governs.
What Is a DSCR HELOC?
A DSCR HELOC is a revolving line of credit secured by a rental you keep, qualified on the property’s rent instead of your personal income. Think of a rental that covers its own debt, so the lender never builds a debt-to-income ratio for you.
The line comes in one of two forms. It is a standalone second lien behind the first mortgage you keep. Or it is a standalone first lien on a rental with no mortgage. It is never closed with a purchase, never a third lien, and never a line on your own home. The rental can be titled in your LLC, subject to lender program eligibility. The members sign as guarantors.
The label “DSCR HELOC” is informal. No industry body standardizes it, so lenders can build the test differently. That is why a checklist helps. The steps below show how this program’s test works, and they show you what to ask any other lender.
Which DSCR Formula Applies Here?
Two formulas circulate under the same name, and mixing them up causes most of the confusion.
The commercial formula divides net operating income by annual debt service. Re-Leased explains that 1.0 is break-even: income equals debt service with no cushion.
Residential rental programs use a simpler version. They divide monthly rent by a monthly payment. On a DSCR term loan, that payment is principal, interest, taxes, insurance and any association dues. On this line, the qualifying payment is different, and the next section covers it.
| Factor | Commercial test | Residential DSCR term loan | This DSCR HELOC |
|---|---|---|---|
| Top number | Net operating income | Gross monthly rent | Qualifying monthly rent |
| Bottom number | Annual debt service | Full monthly payment (PITIA) | Stress payment on full line |
| Taxes and insurance | In operating costs | In the payment | Not in the qualifying payment |
| Floor on this program | Varies by lender | Varies by program | 1.10x |
A stated minimum of 1.10x at one lender can mean something different at another, since the label is informal and each lender builds its own test. Always compare the method, not just the number.
The Checklist: Seven Steps in Order
Work through these in order. Each step sets up the next one.
1. Confirm the property fits. The rental must be a single-family home, PUD, townhome, two-to-four-unit building, or condominium. Lots up to 10 acres are also eligible. Rural-designated property, row homes, condotels, leaseholds and age-restricted communities are outside this lane. A two-to-four-unit building can have at most one vacant unit.
2. Confirm the lien position. If you keep a first mortgage, the line is a second lien. If the rental has no mortgage, the line is a first lien. A rental with a mortgage cannot take a first-lien line.
3. Establish the rent. The program needs a lease in place. Rent used for lender review is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The market rent comes from the appraiser’s rent schedule. Fannie Mae’s forms library shows the standard rent schedule forms: Form 1007 for single-family homes and Form 1025 for small multi-unit buildings.
4. Build the qualifying payment. The lender takes the entire credit limit and runs a fully amortizing payment on it. The rate used is the start rate plus 2 percentage points. That is a stress payment. It is principal and interest only. The rate itself comes with the lender’s disclosures, not from this page.
5. Divide. Qualifying monthly rent divided by the stress payment gives the ratio.
6. Compare to the floor. The program minimum is 1.10x. Clearing it is necessary, not sufficient.
7. Run the other gates. Check combined leverage, credit score, valuation path and seasoning, covered below.
Why the Payment Is Built on the Whole Line
A HELOC does not have one fixed payment. The CFPB’s HELOC brochure explains that a line has a draw period and then a repayment period. It also explains that a variable rate can change your payment even if you borrow nothing more, and that payments can rise when repayment begins.
An underwriter needs one steady number for the bottom of the ratio, so the stress payment on the full limit does that job. It tests whether the rent could carry the line if you drew all of it and the rate moved up.
On this program, the real draw rules are specific. The draw period is 5 years, interest-only on the drawn balance. Then comes a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. The qualifying payment assumes the full limit is drawn and amortized, which is heavier than the payment you will actually make during the draw period.
A Worked Example in Ratios (Modeled, Not Market Data)
Run the numbers on a modeled rental. These inputs are assumptions for illustration, and the lender’s own calculation governs.
The pass case. Say the lease and the appraisal’s market rent land close together, so rent used for lender review is clear. Rent covers the stress payment on the full line at about 1.25x. That clears the 1.10x floor with room to spare.
The fail case. Now suppose a second rental has rent used for lender review that covers its stress payment at only 1.05x. That misses the floor, even if the owner plans to draw just part of the line later.
The fix. The stress payment scales with the line size. Cut the requested line by a fifth, and the payment on the full limit falls by a fifth too. Coverage then rises from 1.05x to about 1.31x. A smaller line also lowers total leverage, so one change helps two gates at once.
A higher lease helps only as far as it is supported. If the lease sits above the appraisal’s market rent, the lease counts only when three months of receipts support it. Otherwise the lower number rules.
Leverage: The Gate Beside the Ratio
Coverage can pass while leverage fails. Leverage is measured against value. On a second lien, the measure is combined loan-to-value (CLTV), which is your first mortgage balance plus the new line, divided by value.
On an investment rental, through select programs and subject to underwriting:
- Second lien: up to 70% CLTV at a 720 credit score or better, on lines from $50,000 up to $500,000. Below 720, there is no second-lien tier.
- First lien (rental with no mortgage), lines up to $500,000: up to 75% LTV at 740 or better, and up to 70% LTV from 700 to 739.
- First lien, lines above $500,000: up to 65% LTV at 720 or better, with lines running to $1,000,000. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Picture a rental where the first mortgage sits at 45% of value. A new line that takes the combined figure to 70% fits the second-lien ceiling. A line that pushes it to 72% does not, however strong the rent looks. A declining-market flag can lower the ceiling by 5 points, so the tier is a ceiling, not a promise.
For the file itself, no traditional personal-income documentation, W-2s or personal income calculation are required, subject to lender guidelines. Credit history still matters. The program wants no 30-day mortgage late in the last 12 months and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves or cash to close are required. Each borrower can hold at most 5 loans or $2,500,000 with the program.
Lines up to $400,000 can use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
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).
Where the General Rule Breaks
The first mortgage on a second lien. Whether the first-mortgage payment joins the qualifying payment on a second lien is not something to assume. Confirm on the file how the lender treats it. The lender’s coverage calculation governs.
Short-term rentals. The rent schedule is often well below what a short-term rental actually earns, and some lenders apply an expense factor to short-term income before running the ratio. 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.
Rent haircuts at lenders. Some lenders in the market count only part of the rent before dividing, or add management costs to the bottom number. A 1.10x elsewhere is not the same test as 1.10x here.
Commercial-style bank tests. A bank “DSCR” can ask for historical income and add vacancy factors. That is closer to the commercial formula than to rent over payment.
Property outside the lane. A rental listed for sale in the last 2 months, or one with a solar lien, is 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.
Common Calculation Mistakes
- Testing the drawn balance instead of the full limit.
- Putting taxes and insurance inside the qualifying payment on this line. They are not part of it.
- Using the lease when the appraisal’s market rent is lower and no receipts back the lease.
- Leaving out the vacant-unit limit on two-to-four-unit buildings.
- Treating a 1.10x floor as a pass. Leverage, credit and valuation still apply.
- Assuming the 70% second-lien cap works like a first-lien tier. Second lien is CLTV, first lien is LTV.
Questions to Ask Any Lender
- Is the stress payment built on the full limit or the drawn balance?
- Are taxes, insurance or association dues part of the bottom number?
- On a second lien, how is the first-mortgage payment treated?
- What are the combined leverage tiers by credit score and line size?
- How are draws and the repayment period structured?

Key Terms Defined
- DSCR (debt service coverage ratio): the rental’s rent divided by the payment the lender tests it against.
- Qualifying payment: the single payment number the lender uses for the ratio; here it is a fully amortizing stress payment on the entire line.
- Stress payment: a payment built at a rate above the start rate, here the start rate plus 2 percentage points, to test the rent under pressure.
- CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
- Form 1007: the appraiser’s single-family rent schedule, which estimates market rent.
- Draw period: the stretch when you can borrow from the line, 5 years and interest-only on the drawn balance here.
Frequently Asked Questions
Does drawing less than the full line lower the payment used for the ratio?
No. The qualifying payment is built on the entire credit limit, so a smaller draw does not help the ratio. Asking for a smaller line does. Remember that at least 80% of the line is drawn at closing on this program, so the line you request is close to the line you carry.
Is the DSCR formula the same as net operating income divided by debt service?
Not for this line. Rent-qualified programs divide rent by a payment instead. On this program, that payment is principal and interest on the full line at the stress rate.
Which rent counts if my lease is higher than the appraisal’s market rent?
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. If you can show those receipts, the higher lease can count. Without them, the lower figure is used.
How long must I own a rental before I can open this 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). Both are measured by recorded dates, so check your closing paperwork before you apply.
Can my LLC hold the rental?
Yes, subject to lender program eligibility. The LLC 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.
