The Quick Read: A DSCR HELOC on a two-to-four-unit rental qualifies primarily on the building’s rent covering a stress payment on the whole credit line, subject to lender guidelines, and having every other unit leased is the normal condition for passing the vacancy limit, not a bonus. A two-to-four-unit property may have at most one vacant unit, so leases on the remaining units carry the file. The line is tested at its full limit, not the drawn balance.
- The line is a standalone second lien behind the first mortgage you keep, or a first lien on a rental with no mortgage.
- Minimum 1.10x coverage, using the full credit limit in the stress payment.
- Rent is the lesser of the appraiser’s market rent and the lease, unless three months of receipts support a lease above market.
- At most one vacant unit on a two-to-four-unit property, and a lease in place is required.
- No traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income calculation, subject to lender guidelines.
Landlords with a duplex, triplex or fourplex ask this question because the building’s rent decides everything. The mechanics below come from how the wholesale network places these lines. Programs change, and every file is underwritten individually.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied rental, qualified on the property’s rent instead of the owner’s personal income. The label is a market term, not a standardized product, so details differ by program.
A HELOC in general is an open-end line. The CFPB explains that you can borrow repeatedly up to your limit during a draw period, then move into a repayment period. When a first mortgage already exists, the CFPB describes the line as a second mortgage paid on top of the first.
The network’s version works two ways. It is a standalone second lien behind the first mortgage the owner keeps, or 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 the owner’s own home. An LLC can hold title (subject to lender program eligibility), with the members signing as guarantors.
A standard bank HELOC on a rental is different. Bank desks tend to judge personal credit, verified income and debt-to-income. One investor on a BiggerPockets thread lists a 43% ceiling on that ratio. That is one investor’s account of bank desks, not this program’s rule. When that desk declines, a rent-based second lien is the usual alternative. The broader comparison sits in the complete DSCR loans guide.
What Does “All Other Units Leased” Actually Prove?
It proves the building is producing rent on paper, and it keeps the file inside the one-vacancy limit. It does not prove the rent counts at the lease figure.
On a two-to-four-unit building, at most one unit may be vacant. If you are at that limit, every other unit needs a lease in place. Leases show tenants, terms and rent. A rent roll is the unit-by-unit list of those tenants, lease dates and amounts. Together they give the underwriter a clean read.
Here is what the leases do not settle:
- The appraiser’s market rent still sits next to each lease. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
- A lease far below market holds the total down even though it is signed.
- A fully leased building can still miss 1.10x if the credit limit is large.
- A building with one vacancy can still pass if the other units carry enough rent.
So treat leases as the floor of the file, not the finish line.
How Rent Is Counted, Unit by Unit
For a two-to-four-unit property, the valuation carries a per-unit market rent. Programs borrow agency form names to describe it. Form 1025 is the small residential income appraisal with per-unit rents, and Form 1007 is the single-family rent schedule. DSCR loans are not agency products. The forms just give a standard layout.
The steps run in order:
1. Pull each unit’s executed lease and note the monthly rent.
2. Compare each lease to the appraiser’s market rent for that unit.
3. Take the lesser figure for each unit, unless three months of receipts support a lease above market.
4. Add the units together for gross monthly rent.
5. Divide by the qualifying payment to get the coverage ratio.
The qualifying payment is a fully amortizing payment on the entire credit limit at a stress rate. Taxes and insurance are not part of it. The minimum is 1.10x. Confirm on the file how the lender treats the first-mortgage payment on a second lien, since the lender’s own coverage calculation governs.
Here is the part that trips people up. Coverage is tested on the full limit even if you draw less later. A bigger limit means a bigger stress payment and a lower ratio. Right-sizing the line often matters more than the headline CLTV.
Worked Example: Duplex Versus Fourplex With One Vacancy
These are illustrations of the arithmetic only. The lender’s own calculation governs.
Picture a fully leased duplex where both units rent at market. Rent covers the stress payment at about 1.25x. Everything is documented, so the file reads cleanly.
Now picture a fourplex with one vacant unit and three leased. The vacant unit often counts at the appraiser’s market rent, if the program allows it. In the network’s program, one vacancy is the ceiling, so the other three units need leases. Say rent still covers the stress payment at about 1.15x. It clears 1.10x, but barely.
Take the same fourplex and request a larger line. The stress payment rises, and the ratio could drop to roughly 0.95x. That sits below the 1.10x minimum. The fix is a smaller limit, not a different building.
One more case. Two vacant units on that fourplex exceed the one-vacancy limit. Coverage math does not matter at that point.
| Scenario | Vacant units | Coverage read | Result |
|---|---|---|---|
| Duplex, all leased | 0 | About 1.25x | Clears 1.10x |
| Fourplex, one vacant | 1 | About 1.15x | Clears, thin margin |
| Fourplex, larger line | 1 | About 0.95x | Below 1.10x |
| Fourplex, two vacant | 2 | Not tested | Outside vacancy limit |
When the “Other Unit” Isn’t a Simple Tenant
Leases differ in quality. Here is how common cases tend to land, since underwriters look at what the document actually proves.
| Lease situation | Likely effect |
|---|---|
| Lease below market | Lower figure counts |
| Lease above market | Market rent counts, unless three months of receipts support the lease |
| Month-to-month or expired | Often market rent, backed by payment history |
| New lease on a long-vacant unit | Counts if executed; payment proof helps |
| Family-member tenant | Expect extra questions on the lease and receipts |
Short-term rental treatment varies by program, and 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. A building the owner lives in is outside this program entirely.
The practical habit is the same in every case. Pair the lease with payment records so the rent has evidence beyond the signature.
Requirements Beyond the Leases
Leases are one piece. The rest of the file looks like this, subject to underwriting and select program terms.
Leverage. On a second lien, combined loan-to-value (the first mortgage balance plus the new line, divided by value) reaches up to 70% at a 720 credit score or better, on lines up to $500,000. On a first lien on a rental with no mortgage, loan-to-value reaches up to 75% at 740 or better and 70% from 700 to 739 on lines up to $500,000. First-lien lines above $500,000 and up to $1,000,000 are capped at 65% at 720 or better. A declining-market flag lowers the ceiling 5 points. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Credit and history. Second liens need a 720 score and first liens need 700. There can be no 30-day mortgage late in the last 12 months. A bankruptcy, foreclosure, short sale or deed-in-lieu needs 48 months behind it. No reserves and no cash to close are required.
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).
Line mechanics. Lines start at $50,000. At least 80% of the line is drawn at closing, and later draws are at least $5,000. The draw period is 5 years interest-only on the drawn balance, then 25 years of amortizing repayment, with a 30-year maturity. The rate is variable.
Limits. No more than 5 loans or $2,500,000 per borrower with the program. 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.
Property. Eligible types include single-family, PUD, townhome, two-to-four units and condominiums. Rural property, row homes, condotels, leaseholds, mixed-use and commercial property are out.
Because the line is a lien on the property, the CFPB warns that falling behind could cost you the property. Hazard insurance covers both liens, with flood coverage where required.
HELOC Versus Purchase or Cash-Out on Vacancy
Closed-end DSCR purchases and refinances handle vacancy differently from a line. A purchase or cash-out often tests a fixed payment on one loan amount. A line tests a stress payment on the whole limit, and the vacancy cap is tighter here. Searchers often mix the two, so name the product before comparing.
The usual reason to choose a line is to keep a low-rate first mortgage in place. A DSCR cash-out refinance replaces that first mortgage instead, which makes sense when the first mortgage is not worth keeping.
Pre-Application Checklist
- Executed leases for every leased unit, with payment records.
- A current rent roll, unit by unit.
- Title held at least 6 months, and no purchase or refinance in the last 6 months.
- Entity documents if an LLC holds title, with guarantor details.
- Hazard insurance in force, with flood coverage where required.
- A credit report that meets the 720 or 700 tier.
- A line size sized against the stress payment, not just the equity.
If a second unit is still vacant, lease it and collect payment history before applying. If the file fails the coverage test, the usual moves are a smaller limit, a lower-leverage structure, or a DSCR cash-out refinance. Lendmire’s piece How to Qualify for an Investment Property HELOC With All Other Units Leased covers the lease-side questions in more depth.
Key Terms Defined
Combined loan-to-value (CLTV): the first mortgage balance plus the new line, divided by the property’s value.
Debt service coverage ratio (DSCR): gross monthly rent divided by the qualifying payment.
Draw period: the stretch when you can borrow from the line, interest-only on the drawn balance.
Rent roll: a unit-by-unit list of tenants, lease terms and rents.
Stress payment: a fully amortizing payment on the full credit limit at a higher test rate, used only to qualify.
Frequently Asked Questions
Do all units need to be leased?
All but one. A two-to-four-unit property may have at most one vacant unit, and a lease in place is required. Leasing every other unit documents the rent and keeps the file inside that limit.
Does one vacant unit disqualify the file?
No, as long as the building still clears 1.10x. Rent still covers the stress payment at about 1.15x in the one-vacancy case, which clears the minimum, but barely, so size the line carefully.
Are tax returns or W-2s required?
No. The rent qualifies the line, with no traditional personal-income documentation, W-2s, pay stubs or personal income calculation, subject to lender guidelines. Credit, equity, title, insurance and valuation are still reviewed.
Is the test on the drawn amount or the full limit?
The full limit. The stress payment is built on the entire credit line even if you draw less later.
How does seasoning work?
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).
