The Quick Read: A below-market lease holds the coverage ratio down and limits the largest line the rent can support, though the rental still fits the program. A lease must be in place. The rent must cover a stress payment on the entire credit limit at 1.10x or better, subject to underwriting.
- Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
- The coverage test runs on the whole credit limit, not the drawn balance.
- A below-market lease is fixed by raising the documented rent or shrinking the line, and a higher appraisal number does not help.
- A vacant rental does not fit this program until it is leased.
- Combined loan-to-value is a separate gate from the rent test.
You own a rental, your tenant has paid the same rent for years, and that rent now sits under what the unit would fetch today. You want a home equity line on the property without refinancing the first mortgage you like. The question is how a lender treats that lease. The answer is mechanical, and once you see the steps you can predict the result before you apply.
A DSCR HELOC is a revolving line of credit on a rental you keep. Across Lendmire’s wholesale network, the line is written as a standalone second lien behind your first mortgage, or as a standalone first lien on a rental with no mortgage. It is reviewed on the property’s rent, not on your paycheck or tax returns. Lendmire is a broker that arranges the line through a wholesale lender, and every figure below is subject to underwriting.

Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the qualifying monthly payment. A result of 1.10x means rent covers the payment with 10% to spare.
HELOC: a home equity line of credit, a revolving credit line secured by property you already own.
Lien position: your place in line for repayment. A second lien sits behind your first mortgage. A first lien is the only mortgage on the property.
Stress payment: the payment the lender uses for the coverage test. Here it is a fully amortizing payment on the entire credit limit, at the starting rate plus 2 percentage points. It is a testing number, not a prediction of what you will pay.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value. On a first-lien line with no other mortgage, the same idea is simply LTV.
Market rent: what the appraiser estimates the unit would rent for today, documented on a rent schedule.
Below-market lease: a signed lease at a rent lower than market rent.
Seasoning: a required waiting period after you buy or refinance a property before you can borrow against it.
Which Rent Does the Lender Count?
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. That single sentence answers most questions. Programs choose their own treatment here, because it is an underwriting convention and not a law. Some use the lease only and some use market rent only, while this HELOC uses the lesser-of approach.
For a below-market lease, the lease is the counted rent. The appraiser’s higher number does not lift it. For an above-market lease, the extra rent counts only when you can show three months of receipts, meaning proof the tenant actually paid that amount. Without those receipts, the appraisal figure governs.
| Your lease vs. market | Rent counted | Effect |
|---|---|---|
| Below market | The lease | Ratio stays low until the lease resets |
| At market | Either (they match) | Cleanest file |
| Above market, no receipts | Market rent | No boost from the lease |
| Above market, 3 months of receipts | The lease | Extra rent counts |
The market rent figure comes from the appraisal side of the file. McKissock explains that appraisers use Form 1007 to collect data from comparable one-unit rentals to document estimated monthly rental rates. It adds that the lender decides how that rental income is used. Form 1025 serves the same purpose on two-to-four-unit properties. On this line, the lender’s coverage calculation is the final word.
On a two-to-four-unit building, the rent is chosen unit by unit. The below-market unit counts at its lease rent. The other units count at the lesser of lease or market, unless three months of rent receipts support a lease above market. A building with one deeply discounted unit can therefore come in lower than the market study alone would suggest.
How a Below-Market Lease Changes the Coverage Test
A below-market lease lowers the top of the fraction, and the bottom does not move. The test divides monthly rent by the stress payment on the entire credit limit, and the result must reach 1.10x. The drawn balance does not matter for this test. A $300,000 line is tested as if you drew all of it, even if you plan to draw less later.
Run the numbers as a ratio. Suppose market rent would produce roughly 1.25x coverage on the line you want. That is a modeled assumption, not a market figure. If your lease runs 10% below market, the counted rent drops to 90% of that, and coverage falls to about 1.125x. The file still clears 1.10x, but with almost no room. If the lease runs 15% below market, coverage falls to about 1.06x, and the line as requested does not pass.
Two points make this easier to handle than it sounds.
First, on this program the qualifying payment is principal and interest on the full line at the stress rate. Taxes and insurance are not part of it. A rent gap therefore passes through to the line size roughly in proportion, instead of being magnified by fixed costs. A lease 15% under market trims the maximum supportable line by about that same share, all else equal.
Second, line size is your lever. Because the stress payment scales with the credit limit, a smaller line lowers the bottom of the fraction. In the example above, trimming the requested line by a few percent brings the 1.06x file back to 1.10x. You often cannot raise the rent today, but you can ask for less credit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment inside its coverage calculation. That detail shapes how much room the rent leaves, and the lender’s own calculation governs.
What Else the Lender Needs
The rent test is one gate among several. A below-market lease can clear the ratio and still stall at another step, so check them all.
A lease in place is required. This is a hard gate. A market-rent study does not replace it on this HELOC. A rental with no tenant in place does not fit this program until it is leased. On a two-to-four-unit property, at most one unit may be vacant.
Combined leverage. Value limits the line separately from rent. On a second lien, CLTV goes up to 70% at a 720 credit score or better, on lines from $50,000 to $500,000. On a first lien with no mortgage, LTV goes up to 75% at 740 or better and 70% from 700 to 739, on lines to $500,000. First-lien lines above $500,000 run to $1,000,000 at a 65% LTV ceiling at 720 or better. Subject to underwriting, a declining-market flag lowers the ceiling 5 points. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Credit and history. A second lien needs a 720 minimum score and a first lien needs 700, using the lender’s own credit report. 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. It requires no reserves.
Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
Seasoning. 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).
Borrower and property. U.S. citizens, permanent residents and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not. Eligible property includes single-family, PUD, townhome, two-to-four-unit and condominium properties. Rural-designated property, row homes, condotels and leaseholds are outside the program. The rental must be non-owner-occupied, so this line is never available on your own home. Vesting in an LLC is allowed, subject to program terms, with the members signing as guarantors.
Draw rules. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. The draw period is 5 years of interest-only payments on the drawn balance. A 25-year repayment period follows, for a 30-year maturity. The rate is variable. The rate and pricing terms come with the lender’s disclosures.
Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
Documents for a Below-Market File
A below-market lease is not a red flag when the paperwork is clean. Expect to provide the executed lease and any amendments, and proof the tenant is paying that rent, such as bank deposits. The lender adds the appraisal’s rent schedule. On a two-to-four-unit property, add a rent roll showing each unit.
Informal arrangements cause trouble. A handshake rent with deposits that vary month to month is hard to document, so get the lease on paper before you apply.
How to Fix a Thin Ratio Caused by a Low Lease
Every fix either raises the rent that counts or lowers the payment you are testing. Here they are side by side.
| Option | What it changes | Tradeoff |
|---|---|---|
| Renew at documented market rent | Raises counted rent | Needs the tenant’s agreement |
| Request a smaller line | Lowers the stress payment | Less equity reached |
| Document rent receipts | Supports an above-market lease | Does not lift a below-market one |
| Wait for the lease to reset | Raises counted rent later | Delays the draw |
| Compare a first-lien cash-out refinance | Different product, different rules | Replaces the first mortgage |
Renewing at market before you apply is the cleanest repair when the tenant agrees. Mind notice periods, local rent rules and the chance that the tenant leaves instead of paying more. A vacant unit is worth less to this line than a tenant at a modest discount.
Do not go the other way. A discounted lease signed just before the appraisal can lower the counted rent, and the lender then uses that lower number. Filling a unit cheaply right before you borrow works against you.
Remember that clearing the ratio does not mean the property earns a profit. Repairs, vacancy, management, utilities and capital expenses all sit outside the calculation. A file at 1.12x passes on paper but has little cushion if the appraisal’s market rent comes in light.
Where the General Rule Breaks
The lesser-of rule holds for most situations, but several cases bend it. Each depends on the program and the specific lender, so confirm the treatment on your file.
Month-to-month or expired lease. A lease in place is still required on this HELOC. Some programs count market rent in this situation, with the prior lease as support. That can help a below-market tenant, but confirm whether an expired lease satisfies the lease requirement before you apply.
Vacant property. No lease means no fit. A first-lien DSCR cash-out refinance is the usual alternative once you have a tenant, or even before.
Related-party tenant. A below-market or informal lease to a family member can be treated conservatively. Expect scrutiny of whether the rent is real and documented.
Voucher or subsidized tenant. The lowest credible figure is typically used, with the housing contract, lease and appraisal as support.
Short-term rentals. Form 1007 is the wrong tool for nightly income. Fannie Mae’s appraiser guidance says the form cannot be used to estimate the nightly fee for a short-term rental, and appraisers must use rental comparables with monthly lease rates. HousingWire reports that forcing the form onto short-term rentals often distorts DSCR calculations, producing artificially low ratios.
Program variation. Some lenders lean on actual rent instead of the lesser-of rule. This line’s own parameters are the ones above, so do not assume another product’s treatment carries over.
DSCR HELOC or Cash-Out Refinance With a Low Lease?
A DSCR cash-out refinance replaces your first mortgage, while a DSCR HELOC leaves it alone. That difference matters most when your existing first mortgage is one you want to keep. It also changes how the lease interacts with the file.
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Lease required | Yes, always | Program-dependent |
| Vacant rental | Does not fit | May be an option |
| Rent test basis | Full credit limit | Loan amount |
The cash-out column describes that product generally and varies by program. If your lease is below market and you have no tenant problem, the HELOC is workable when the ratio clears. If the unit is vacant, or the low lease keeps the ratio under 1.10x on any line size you would accept, the cash-out route deserves a look — LTV and terms adjust, subject to underwriting.
Who Should Wait or Skip
Wait if your lease renews soon and the tenant would agree to a market-rate renewal. The same rent figure that holds your ratio down today may be a signature away from helping you.
Skip this product if the rental is vacant, owner-occupied or in a property category the program excludes. Skip it too if your credit score sits under the 720 second-lien minimum while you keep a first mortgage. The first-lien option exists only on a rental with no mortgage, so a borrower with a mortgage cannot use it.

Frequently Asked Questions
Does a below-market lease disqualify me?
No. The lease stays as the counted rent, and the file still fits the program. The catch is the coverage ratio, which stays low until the lease resets. You qualify only if the lease rent clears 1.10x against the stress payment on the full line, subject to underwriting.
Can I use market rent instead of my lease?
Not when the lease is lower. The counted rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A market-rent study also cannot stand in for a lease, because a lease in place is required.
Does an above-market lease help?
Only with proof. Three months of rent receipts allow an above-market lease to count. Without them, the appraisal’s market rent governs, and the extra rent does nothing for the ratio.
What if my tenant is month-to-month?
It depends on the program. A lease in place is required on this HELOC, so confirm early whether a month-to-month or expired lease satisfies that gate. If it does not, renewing with a signed lease is the usual path.
How many months of ownership does this line require?
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).
What To Do Next
Pull your lease and a realistic market rent figure side by side before you apply. If the gap is small, you may only need a slightly smaller line. If the gap is large, consider a renewal first. 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. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. This is not a commitment to lend.
However long your tenant has stayed, the paperwork on that lease decides how much equity the property lets you reach.
