The Quick Read: Usually the rent that counts is the lesser of the signed lease and the appraiser’s market rent, and that rent must cover a stress payment on the entire credit limit at 1.10x or better, so rent sets one ceiling on your line while equity sets the other. Whichever ceiling is lower decides the line, subject to underwriting.
- The lease and the appraiser’s rent estimate are both tested, and the lesser one counts unless three months of rent receipts support a lease above market.
- The test runs on the full credit limit, not on the amount you draw.
- Equity is a separate cap: combined loan-to-value (CLTV) tops out at 70% on a second lien at a 720 score or better.
- A low appraisal rent can shrink the line even when your lease looks strong.
- Any coverage number you run before the appraisal is an estimate until the rent report arrives.
A DSCR HELOC is a revolving line of credit on a rental you keep. It sits as a standalone second lien behind your first mortgage, or as a first lien on a rental with no mortgage. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For the full picture of how these loans work, see Lendmire’s complete DSCR loans guide.
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 drives the whole sizing exercise.
Two documents feed it. The lease shows what the tenant actually pays. The market rent comes from the appraiser, who reports what comparable homes rent for. A lease in place is required, so a vacant rental does not fit this lane.
Programs differ on this point. Across the lenders in Lendmire’s wholesale network, some take the lesser of the two numbers, some lean on the appraiser’s figure, and some lean on the lease, unless three months of rent receipts support a lease above market. The program described here uses the lesser-of rule with the receipts exception.
Key Terms Defined
Form 1007: the Single-Family Comparable Rent Schedule, an appraisal attachment where the appraiser estimates monthly market rent for a one-unit investment property. Fannie Mae’s appraiser guidance describes it that way. The agency created the form for its own loans, but DSCR lenders borrow it as a rent opinion and set their own rules for using it.
Form 1025: the small residential income property appraisal report, which includes the rent analysis for a two-to-four-unit property. Per a TrueCap explainer on investment property appraisals, the 1007 attaches to a one-unit appraisal and the 1025 covers two to four units.
Lesser-of rule: counting the lease or the market rent, whichever is lower.
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment. The minimum on this program is 1.10x.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is built to be higher than the payment you would actually owe at first.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
How the Rent Turns Into a Maximum Line
Rent caps the line by capping the payment the property can carry. Divide gross monthly rent by 1.10, and you get the largest qualifying payment the rent can support. The lender then converts that payment into a line size using its stress payment on the whole limit.
Three details matter here.
The test runs on the whole limit. The stress payment is figured on the entire credit limit, not on your drawn balance. This program requires at least 80% of the line to be drawn at closing anyway, so the gap is small. Still, a bigger requested limit means a bigger stress payment against the same rent. A bigger line lowers your ratio.
Taxes and insurance are not in the qualifying payment. The qualifying payment is principal and interest on the full line at the stress rate. Keep taxes and insurance in your own cash-flow budget, though, because they are real costs.
The lender’s calculation governs.
The line is the smaller of the rent-supported limit and the equity-supported limit. Rent, not your personal income, decides how large the line can be. No traditional personal-income documentation, W-2s or personal income calculation are involved, subject to lender guidelines.
The Equity Ceiling Is the Second Gate
Leverage limits depend on lien position and credit score. These are ceilings, not offers, and every file is underwritten individually.
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien, non-owner-occupied rental | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien, rental with no mortgage | 740 or better | 75% LTV | Up to $500,000 |
| First lien, rental with no mortgage | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, rental with no mortgage | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
To find your equity ceiling, multiply the property’s value by the CLTV cap, then subtract your first mortgage balance. A declining-market flag on the property can lower the ceiling by 5 points.
How do you tell which gate binds? Run both. If you owe little on the first mortgage and the rent is modest, rent usually binds first. If the rent is strong but the first mortgage is large, equity binds first. Rent-bound files react to every change in the lease or the appraisal. Equity-bound files react to the property value.
Worked Example: When the Lease and the 1007 Match, and When They Don’t
These are modeled assumptions, expressed as ratios, not market data.
Case 1: lease and market rent agree. Say you request a line and the counted rent produces coverage of about 1.25x. That clears the 1.10x minimum with room to spare. Equity may still limit the line, but rent is not the problem.
Case 2: the appraisal rent comes in 15% below the lease. The lesser-of rule drops the counted rent by 15%. Coverage falls from about 1.25x to roughly 1.06x (1.25 × 0.85), which is below 1.10x. Same property, same tenant, and the file no longer clears.
The fix on the same rent: shrink the request. The stress payment scales with the size of the limit, so cutting the line roughly 3% to 4% brings coverage back to about 1.10x (1.06 ÷ 1.10 is roughly 0.97). Whether that is enough depends on the lender’s own calculation and on your equity ceiling.
Case 3: the lease sits 15% above market. Under the lesser-of rule alone, the market figure would govern. On this program, three months of rent receipts that support the lease can bring the lease figure back in, subject to underwriting. Without receipts, you are in Case 2.
The pattern is consistent. Rent above the market figure earns nothing without proof, and rent below it hurts.
Lease vs. Form 1007: What Happens in Each Case
| Situation | Counted rent | What it means for the line |
|---|---|---|
| Lease above market, no receipts | Market rent | Line sizes off the lower figure |
| Lease above market, 3 months of receipts | Lease, subject to underwriting | Line can size off the lease |
| Lease below market | The lease | Ratio and line shrink |
| Lease and market rent equal | Either figure | No gap to manage |
| No lease in place | Not eligible | Fits a different DSCR product |
Edge Cases That Change the Answer
Below-market lease. The lease governs, so the ratio and line size drop. Renewing at documented market rent before the appraisal can lift the figure. Do not sign a discounted lease just ahead of the valuation.
Vacant, month-to-month or expired lease. This lane requires a lease in place. A vacant rental does not fit, though many DSCR cash-out and purchase files can run on market rent alone. If your lease has rolled to month-to-month, confirm with the lender whether that satisfies the lease requirement.
Two to four units. The appraisal uses Form 1025 instead of the 1007, and at most one unit may be vacant.
Nightly-booked rentals. The Fannie Mae guidance states that the 1007 cannot estimate a nightly short-term-rental fee, and the appraiser must use comparables leased on a monthly basis. A lease is required here anyway. 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.
Valuation path and the rent report. 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. Lines above $400,000 need a full interior appraisal (Form 1004, 1073 or 1025). The 1007 or 1025 rent analysis comes with the appraisal path, so on a smaller line, ask how the lender will establish market rent.
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).
Title and entity. Vesting in your LLC is allowed on this program, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
Property types outside this program. Rural-designated property, condotels, row homes and leaseholds are out, along with several others. A property listed for sale in the prior 2 months is also out.
Why the 1007 Comes In Low
Appraisers pick comparable rentals, and the picks drive the number. A low result usually traces to the comps themselves: different bedroom counts, weaker locations, or leases signed under older conditions. Condition and finishes also move the estimate.
Your options are practical. Ask whether the lender will review the rent figure if you bring better rental comparables. Policies vary, so ask before you pay for anything. Renewing a below-market lease at documented market rent can also help on a later file.
Pre-Application Self-Check
Before you apply, work through this list:
1. Pull the signed lease and note the monthly rent.
2. Compare it with a realistic rent comparison for similar homes nearby.
3. If the lease is above market, gather three months of rent receipts.
4. Divide gross rent by 1.10 to see the payment ceiling your rent can carry.
5. Multiply value by the CLTV cap and subtract your first mortgage balance to see the equity ceiling.
6. Ask for the line you need. Extra headroom raises the stress payment and lowers the ratio.
7. Confirm the title and entity setup, and check the six-month clocks.
The file itself includes the lease, credit report, valuation and entity papers if the property is in an LLC. It also includes insurance and title. It is a documented file. It just does not run through your personal income.
The Variable-Rate Problem You Still Own
The line carries a variable rate. The Consumer Financial Protection Bureau explains that a HELOC is a revolving line you draw on up to the limit during a draw period, and that payments can change because the rate is usually variable. That is why the stress test exists. Here, the draw period is 5 years interest-only on the drawn balance, followed by a 25-year repayment period, with a 30-year maturity. Later draws must be at least $5,000.
Qualifying at 1.10x does not protect you from rising costs. Check that your actual cash flow still holds when the payment moves. A line you cannot carry through a rough stretch is a cost, not leverage.
Common Misconceptions
A higher lease raises my line. Only when three months of receipts support it. Without proof, the market figure governs.
The 1007 is a lender rule. It is an appraisal form. DSCR lenders borrow it as a rent opinion and set their own treatment.
The ratio runs on my drawn balance. On this program it runs on the entire limit at the stress rate.
The 1007 works for Airbnb-style income. It does not estimate nightly rates.
DSCR means no paperwork. The file carries a lease, credit report, valuation and entity papers. Only the personal income documents are skipped, subject to lender guidelines.
Any big bank will do a HELOC on a rental. Availability varies. Many depository institutions do not offer lines on investment property, which is part of why this niche exists.
Frequently Asked Questions
Does a bigger lease give me a bigger line?
Only when three months of rent receipts support a lease above market. Otherwise the appraiser’s market rent is the figure that counts, so the extra rent adds nothing. A lease below market does hurt, because the lease then governs. Underwriting reviews each file.
Does the test run on what I draw or on the whole line?
It runs on the whole line. The stress payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. At least 80% of the line is drawn at closing, so the difference is small, but a larger limit always means a lower ratio on the same rent.
What if my coverage lands just under 1.10x?
You have a few levers. Request a smaller line, renew a below-market lease at documented market rent, or supply rent receipts if the lease is above market. If none of those work, a DSCR cash-out refinance may fit better, since treatment of rent varies by program.
Can I use a HELOC on a two-to-four-unit rental?
Yes, subject to underwriting. The appraisal uses Form 1025, and the property may have at most one vacant unit. The same lesser-of rent rule and 1.10x minimum apply.
Is this available everywhere?
No. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker that arranges the line through a wholesale lender, and the lender approves it. Terms change, and every file is underwritten individually.
