The Quick Read: A market-rent study is the appraiser’s opinion of what the property should rent for, and on a DSCR HELOC it sets the ceiling on the rent that counts, so an empty house usually needs a signed lease while one empty unit in a small multifamily can lean on the study.
- The line qualifies primarily on property-level rental income covering a stress payment, subject to lender guidelines. Your personal income is not calculated.
- Rent counts at the lesser of the appraiser’s market rent or the lease. The minimum coverage is 1.10x.
- A fully vacant single-family rental generally needs a lease before it fits this program. A two-to-four-unit property may have at most one vacant unit.
- Both the rent coverage and the combined loan-to-value must pass. The tighter one sets your line.
- A rental bought or refinanced inside the last 6 months is not eligible.
Most investors who search this topic picture one thing: an empty rental, a rent estimate from an appraiser, and a credit line. That picture is half right. The study matters a great deal. It just does not replace the lease the way many people hope.
What a DSCR HELOC on a Rental Actually Is
A DSCR HELOC is a revolving credit line secured by a rental you own. It is written either as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, and it is never a third lien. (A home equity line of credit, or HELOC, works like a credit card secured by property: you borrow, repay, and borrow again within limits. The CFPB’s HELOC booklet describes the basic structure.)
The “DSCR” part means the rent drives lender review. DSCR is the debt service coverage ratio: gross monthly rent divided by the qualifying payment. On this program the qualifying payment is a fully amortizing payment on the entire credit limit, figured at the start rate plus 2 percentage points. That is a stress payment. It is deliberately heavier than what you will pay while drawing interest-only.
You need no traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income calculation, subject to lender guidelines. You do need a credit report, a lease, a valuation and a property that fits. The LLC can stay on title, subject to program terms. The members sign as guarantors.
Lendmire is a broker. It arranges this line through a wholesale lender in its network, and the lender underwrites every file individually. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington.
One clarification saves confusion. Some investment-property HELOCs at banks are underwritten on the borrower’s credit, equity and debt-to-income. That is a different product. This one reads the rent.
Can a Fully Vacant House Qualify?
On the program described here, a fully vacant single-family rental generally cannot, because a lease in place is required. The market-rent study does not stand in for the lease. It caps it.
If you are weighing the HELOC against a cash-out refinance on an empty property, Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance on a Vacant Rental Using a Market-Rent Study walks through both routes. A line on a rental you already own has one more requirement: a tenant.
Here is where the study earns its keep on a HELOC:
- Between tenants, with a lease coming. Sign the lease first. The study then confirms the rent is supportable.
- Two to four units, one empty. The program allows at most one vacant unit. The study speaks to that unit’s rent, and the lender’s coverage calculation decides exactly how the empty unit is credited. Ask which treatment applies before you order anything.
- Two or more empty units. The property is outside this lane.
Honestly, the cleanest vacant-rental path is boring: lease it, then borrow against it.
How the Market-Rent Study Gets Built
An appraiser builds the study, not you. The lender orders it, and you generally do not choose the appraiser. For a single-family home or condo, the form is Form 1007. For two to four units, the appraisal on Form 1025 reports market rent for each unit.
The appraiser picks comparable rentals, adjusts for real differences, and lands on an indicated monthly market rent. McKissock, an appraiser-education firm, notes that the form is built around three comparables. It also notes that it documents monthly rent for single-family homes, not nightly rent or business income.
You cannot hand the appraiser a number. You can hand over facts. A list of recent improvements, the unit mix, and any nearby leases you know about give the appraiser better material. A property that is clean, finished and rent-ready tends to produce a more defensible number than one with open walls.
Which Rent Counts?
| Situation | Rent the lender counts |
|---|---|
| Lease and study match | Either; the figure is the same |
| Lease below study | The lease, as the lesser |
| Lease above study | The study figure, as the lesser |
| Two-to-four units, one vacant | Lender’s calculation; study informs the empty unit |
| Single-family, no lease | Generally outside this program |
| Short-term rental use | Study is long-term rent; STR income is not what this line reads |
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.
From Empty Rental to Approved Line, Step by Step
1. Confirm the property fits. It must be non-owner-occupied and one to four units. Single-family, PUD, townhome, two-to-four units and warrantable and non-warrantable condos are eligible property types. The leverage tiers below govern every property type.
2. Check the two timing clocks. 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).
3. Get the lease in place. Single-family needs a lease. A small multifamily may carry one empty unit.
4. Pick the lien position. Keep the first mortgage and add a standalone second lien, or open a first lien on a paid-off rental.
5. Order the valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines use a full interior appraisal. Appraisal waivers are not accepted.
6. Let the study set the rent. The lender compares the study to the lease and takes the lesser.
7. Run both tests. Coverage must reach 1.10x on the stress payment, and combined leverage must sit inside the tier for your credit score.
8. Close and draw. At least 80% of the line is drawn at closing, and never less than $50,000. Later draws are at least $5,000 each.
Every figure here is typical of select programs in the network, subject to underwriting.
The Coverage Test, Worked Two Ways
The stress payment is figured on the whole limit, not just the amount you draw. That detail drives everything.
Run the numbers on a paid-off rental where the lease and the study agree. Say the rent covers the stress payment on your requested limit at about 1.2x. That clears the 1.10x minimum with a little cushion.
Now picture the same rental with a requested limit that pushes coverage to about 1.0x. It fails. The fix is not more paperwork. Because the payment scales with the limit, trimming the requested line to roughly 90% of the original lifts coverage to about 1.11x. These are illustrative ratios, and the lender’s own calculation governs.
The lesson: when the study lands lower than hoped, you shrink the line instead of arguing with the rent.
Equity Is the Other Gate
Rent coverage and equity are separate tests. The line is capped by whichever is tighter.
On a second lien, combined loan-to-value (CLTV) is the first mortgage balance plus the new line, divided by value. The ceiling is 70% CLTV at a 720 credit score or better, on lines up to $500,000. Below 720, there is no second-lien option. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A first lien uses plain loan-to-value (LTV):
| Credit score | First-lien LTV (lines to $500,000) |
|---|---|
| 740 or better | Up to 75% |
| 720 to 739 | Up to 70% |
| 700 to 719 | Up to 70% |
First-lien lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. The first-lien floor is a 700 score. A declining-market flag on the valuation lowers the ceiling by 5 points. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Say your first mortgage already uses 55% of the property’s value and you qualify for 70% CLTV. The room is about 15 points of value, whatever the rent says. The CFPB booklet describes the same logic for any HELOC: the limit is commonly set as a percentage of appraised value minus the existing mortgage balance. That is why the appraisal does two jobs here, value and rent.
If the Study Comes in Low
A low rent number has four realistic answers:
- Reduce the line. Smaller limit, smaller stress payment, higher coverage.
- Ask the lender about a review. Send recent comparable leases you know about. Any reconsideration runs through the lender, and nothing is promised.
- Wait for a stronger lease. A lease below the study already counts at the lease figure, so signing at market improves the file.
- Try a different lender’s program. Across a wholesale network, guidelines on rent treatment differ. A broker’s job is to compare, though this particular line follows the terms above.
Do not count on your own projection. A rent you think the property deserves does not substitute for the study or the lease.
Where the General Rule Breaks
Short-term rentals. The long-term rent form is not designed for nightly income. A property run as an Airbnb does not translate well to a study built on monthly comps.
Heavy rehab. A property that needs real work is rarely rent-ready. It may need short-term financing first and a line after it is stabilized and leased.
Excluded property types. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use are not eligible here. Neither is a property listed for sale in the prior 2 months, or one with a solar lien.
Borrower limits. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Credit rules include 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, and exposure caps at 5 loans or $2,500,000 per borrower with the program.
Owner occupancy. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Federal rules treat credit to acquire, improve or maintain a non-owner-occupied rental as business-purpose, but they change if you expect to occupy the property more than 14 days in the coming year (CFPB Regulation Z, section 1026.3). This line is never offered on an owner-occupied home or a second home.
Coverage versus cash flow. Clearing 1.10x tells the lender the rent supports the debt. It says nothing about repairs, vacancy, management or capital costs. Run your own budget before you draw.
One experience note: in the files the network sees, the study is rarely the surprise. The surprise is the timing, an owner who bought or refinanced five months ago and discovers the seasoning clock is still running. Check the dates first.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment; this program’s minimum is 1.10x.
Market-rent study: an appraiser’s opinion of monthly market rent, built from comparable rentals on Form 1007 (single-family) or the per-unit rents in a Form 1025 report (two to four units).
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Seasoning: the waiting period after you buy or refinance before the property is eligible; here it is 6 months.
Draw period: the stretch when you can borrow from the line. Here it is 5 years interest-only, then a 25-year repayment period, with a 30-year maturity and a variable rate.
Stress payment: the fully amortizing payment on the whole credit limit at the start rate plus 2 percentage points, used only to test coverage.
Frequently Asked Questions
Can I use my own rent estimate instead of the appraiser’s?
No. The appraiser’s study is the independent opinion, and the lender counts the lesser of that figure or your lease. Your own estimate can help you decide whether to apply, but it does not enter the coverage math.
Does a market-rent study replace a lease on a single-family rental?
Not on this program. A lease in place is required, and the study caps the rent the lender will count.
How much can I borrow on a rental with a first mortgage?
A standalone second lien reaches up to 70% combined loan-to-value at a 720 score or better, on lines from $50,000 to $500,000, subject to underwriting. Both the first mortgage balance and the new line count toward that figure, and the 1.10x coverage test applies as well.
Do I have to draw the whole line at closing?
No, but at least 80% of the line is drawn at closing, and never less than $50,000. After that, each draw is at least $5,000, and the draw period is 5 years interest-only before the 25-year repayment period begins.
Can I hold the rental in an LLC?
Yes, subject to program terms. The LLC stays on title, the members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
What This Means for Your Next Move
Start with the lease, the dates and the valuation path, in that order. If the property is leased, past its 6-month mark and in an eligible category, the study and your credit tier will tell you the rest. 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.
