The Quick Read: A DSCR HELOC on a two-to-four-unit rental qualifies primarily on property-level rental income covering a stress payment on the full credit line, subject to lender guidelines. Leased units help only when each lease is documented, matches market rent, and lifts coverage to the program’s 1.10x minimum. Full occupancy is a strong start, but the rent math decides the file.
- The line is a standalone second lien behind your first mortgage, or a standalone first lien on a paid-off rental, through select programs.
- Rent qualifies the line. Your personal income is not calculated, and the LLC can stay on title, subject to program terms.
- Each unit is tested at the lesser of its lease or the appraiser’s market rent.
- A two-to-four-unit building may have at most one vacant unit, so “all other units leased” is the cleanest version of this file.
- Seasoning, credit score, combined leverage and property type can still stop an otherwise full building.

What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line of credit on a non-owner-occupied rental, qualified on the property’s rent instead of your paycheck. DSCR stands for debt service coverage ratio. It measures whether the rent covers the monthly obligation on the property.
The name is a market label, not one standardized product. Three different structures get called a DSCR HELOC, and they underwrite differently.
| Structure | How it qualifies | Do unit rents matter? |
|---|---|---|
| First-lien cash-out refinance | Rent covers the new payment | Yes, heavily |
| Standalone line on a rental | Rent covers a stress payment | Yes, heavily |
| Investment-property line on personal income | Your debt-to-income ratio | Mostly no |
The program described here is the second row. It is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, never a third lien, and never a line on your own home. A HELOC on a primary residence is a different, owner-occupied product.
The CFPB describes a HELOC as an open-end line of credit. You borrow against your equity, repay, and borrow again during a draw period, and the rate is usually variable. Equity is simply the property’s value minus what you owe on it.
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.
What Does “All Other Units Leased” Actually Prove?
It proves one thing: the building has no more vacancy than the program allows. A two-to-four-unit property may have at most one vacant unit, and a lease in place is required. So a building with every other unit leased sits at the edge of the vacancy limit and inside it.
It does not prove the rest. Full occupancy says nothing about whether the leases are at market, whether the rent covers the stress payment, or whether you have enough equity. A fully leased building with cheap leases can fail the coverage test while a building with one empty unit passes.
Think of it as removing one risk, vacancy, while leaving four others on the table:
- Below-market leases that hold the counted rent down.
- A credit line sized too large for the rent.
- Combined leverage above the tier your score allows.
- A property type or borrower type outside the program.
The phrase “all other units” also hints that one unit is different. It might be empty, between tenants, under renovation, or occupied by a relative or by you. Each case gets different treatment, covered below.
How Does the Lender Count Rent, Unit by Unit?
On a multi-unit property, the underwriter reads the rent unit by unit. The appraiser sets a market rent for each unit type, and the lender compares it with the lease on the rent roll. Each unit counts at the lesser of the two, and the results are added up.
A rent roll is a simple schedule listing each unit, its tenant, the monthly rent and the lease end date. On a two-to-four-unit building, the appraisal uses Form 1025, which covers duplexes through fourplexes and weighs both rental income and market value. Form 1007 is the one-unit rent schedule, so ordering one on a duplex is unnecessary.
| Unit situation | Typical counted rent |
|---|---|
| Lease below market | The lease amount |
| Lease at market | The lease amount |
| Lease above market | Market rent, unless receipts support more |
| Month-to-month or expired lease | Market rent, prior lease as support |
| Tenant signed recently | Lease, deposit and payment proof needed |
| Vacant unit | Depends on the lender’s calculation |
On this program, a lease above market may count when you can show three months of receipts, subject to underwriting. Without that history, expect the market figure.
The vacant unit is where lenders differ most. Across the wholesale network Lendmire works with, many programs count an empty unit at the appraiser’s market rent, sometimes with conditions. A few count it at zero. Some treat a heavily vacant building as unleased and cut the leverage. Which one applies depends on the program, so the lender’s own coverage calculation governs.
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. As McKissock explains, the appraisal rent schedule documents monthly rent, not nightly income, and the lender decides how nightly income is treated.
Worked Example: A Four-Unit With One Empty Unit
Run the numbers on a hypothetical fourplex where the four units are roughly equal in rent. These are modeled assumptions, not market data.
Suppose the full building at market rent covers the stress payment at about 1.30x. If the lender counts the empty unit at market rent, the file sits near 1.30x and clears the 1.10x minimum.
Now suppose the lender counts only the three leased units. Each unit supplies about a quarter of the rent, so coverage falls to roughly 0.98x. That is below 1.10x, and the file fails on coverage even though three of four units are leased.
Change one input and the picture shifts again. If the full building covers at about 1.50x, the three-unit count lands near 1.13x. It passes narrowly.
Small buildings take the hardest hit from one empty unit. A fourplex loses a quarter of its counted rent, and a duplex loses half. Larger buildings absorb a vacancy more easily, but five or more units get reviewed commercially instead of under the two-to-four-unit tiers.
One more detail matters here. The lender tests the payment as if you had drawn the entire credit limit, using a fully amortizing stress payment, not the smaller interest-only payment you would actually make. A smaller line produces a smaller test payment, and a smaller test payment produces higher coverage. If the number is close, trimming the line size is often the cleanest fix. Illustrative arithmetic like this is not an approval, and the lender’s own calculation governs.
What If the “Other” Unit Is Not Simply Vacant?
The answer depends on why that unit is different. This table maps the common situations to how the program treats them.
| The other unit is… | What it means for the file |
|---|---|
| Vacant, ready to rent | Allowed once; counted per the lender’s calculation |
| Being renovated | Same vacancy limit applies; rent tested on market rent |
| Leased to a relative | Market rent and closer review |
| Section 8 | Housing contract and lease documented; lower credible figure |
| Occupied by you | Not eligible on this program |
The owner-occupied case deserves a plain statement. This line is only for non-owner-occupied rentals. If you live in one unit of a duplex, the property is not eligible here, and you would look at an owner-occupied home equity product instead.
If you have two or more vacant units in a two-to-four-unit building, the vacancy limit is exceeded. Leasing one of them before you apply brings the building back inside the rule.
Leasing the last unit at or near market rent before the appraisal also makes the file cleaner. A fresh lease with a deposit and first payment on record is easier to underwrite than an open question about what the unit will rent for.
The Gates Beyond Rent
Rent is only one gate. These are the others, stated as typical ceilings and floors through select programs, subject to underwriting.
Leverage on a second lien. Combined loan-to-value, which adds your first mortgage balance and the new line and divides by value, tops out at 70% CLTV on an investment property second lien. That requires a 720 credit score or better, on lines from $50,000 up to $500,000. Below 720, this program has no second-lien option. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Leverage on a first lien. On a rental with no mortgage, loan-to-value reaches 75% LTV at a 740 score or better. It is 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, are capped at 65% LTV at 720 or better. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Credit and history. The floor is 720 on a second lien and 700 on a first lien. Programs typically look for no 30-day mortgage late in the last 12 months. They also look for 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
Seasoning. Seasoning is the waiting period between events. A rental bought or refinanced in the last six months is not eligible, and you need six months of ownership.
Reserves and exposure. The program requires no reserves and no cash to close. It allows at most five loans or $2,500,000 per borrower.
Property. Single-family, PUD, townhome, two-to-four units and warrantable condominiums are eligible. Rural property, row homes, condotels, leaseholds, mixed-use and properties listed for sale in the prior two months are not. A declining-market flag can lower the leverage ceiling.
Borrowers and title. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. An LLC can hold title on an investment property, subject to program terms. Members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment.
Terms. The draw period is five years interest-only on the drawn balance. A 25-year repayment period follows, and the maturity is 30 years. The rate is variable. At least 80% of the line is drawn at closing, and later draws are at least $5,000. 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.
Documents to Gather Before You Apply
The rent is documented, and so is everything else. The file typically needs:
- A signed, dated lease for each occupied unit.
- A rent roll listing every unit, tenant, rent and lease end date.
- Deposit and payment records, especially for recent tenants.
- Proof of ownership and, if the LLC holds title, the entity documents.
- Your first mortgage statement, for a second lien.
- Hazard insurance covering both liens, plus flood coverage where required.
- The credit report the lender pulls, and the valuation the lender orders.
Mismatches slow files down. A rent roll that says one amount while the lease says another invites questions, so align them before submitting.
Step by Step: How to Qualify
1. Confirm the structure. Make sure you are asking for a rent-qualified line, not a line that runs on personal income.
2. Check eligibility. Confirm the property type, the state, the six-month seasoning and your credit score tier.
3. Build the rent roll. List each unit with its lease terms, and line up the lease copies behind it.
4. Estimate each unit at the lesser of lease or market. Add them up and compare against a stress payment on the full line.
5. Size the line. Hold combined leverage under the ceiling for your tier, and trim the line if coverage is thin.
6. Deal with the odd unit. Lease it, document it, or confirm how the lender will count it.
7. Submit for valuation. The lender orders the automated valuation or appraisal, depending on line size.
8. Review the lender’s coverage calculation. The lender’s figure governs, so ask for it rather than assuming yours.
Why Files Stall, and the Fix
The lease sits below market. The lease amount holds the ratio down. Ask the lender before the appraisal whether a market-rate renewal would help, and time the renewal if it does.
Month-to-month tenants. Without a current lease, expect market rent alone, with the old lease as support. Sign fresh leases first.
Line too large. Because the test assumes the full line is drawn, an oversized limit drags coverage below the minimum. Reduce the limit.
Combined leverage too high. If your first mortgage balance plus the new line exceeds 70% CLTV of value, shrink the line or wait for more equity.
Property out of scope. Row homes, condotels and rural designations are outside the program regardless of occupancy.
Seasoning. A rental bought within the last six months waits.
When a file does not fit, a rent-qualified second lien may not be the right tool. A DSCR cash-out refinance replaces the first mortgage instead of sitting behind it. A line qualified on personal income relies on your debt-to-income ratio, and its rules belong to that program. Taking out a line on a rental to buy the next one is common, and the new purchase would carry its own separate DSCR loan.
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.

Frequently Asked Questions
Does a vacant unit disqualify me?
Not automatically. A two-to-four-unit building may have at most one vacant unit on this program, and a lease must be in place on the rest. How the empty unit counts depends on the lender’s coverage calculation, so a building with one vacancy can still qualify if the other rents carry the ratio.
Do I need tax returns or pay stubs?
Not for the income test. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The leases, the credit report and the valuation are all still documented.
Can my LLC hold title?
Yes, on an investment property, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment. The borrowers on the line need not be the borrowers on your first mortgage.
Can I use this on a short-term rental?
Possibly, but the lender decides how nightly income is treated, and the appraisal rent schedule documents monthly rent.
Is this product easy to find?
No. Investment-property home equity lines are scarce at big banks and large retail lenders, which is why many investors look to specialty programs placed through a wholesale network. Availability depends on your state, the property and the program.
