The Quick Read: A DSCR HELOC on a duplex, triplex or fourplex is a revolving line written as a standalone second lien behind your existing first mortgage, or as a first lien on a paid-off rental. It qualifies primarily on the property’s rental income covering the payment, subject to lender guidelines. Which lender fits depends on your credit score, the combined leverage you need, and the building’s lease and vacancy picture. Lendmire is a mortgage broker, so it matches your file to a wholesale lender rather than lending itself.
- The rent qualifies the line, tested at a 1.10x coverage ratio.
- Leverage depends on lien position and credit score, and the leverage section below sets out each tier.
- At most one unit may be vacant, and a lease must be in place.
- At least 80% of the line is drawn at closing, so the line size sets your cash.
What Is a DSCR HELOC on a Small Multifamily?
A DSCR HELOC is a home equity line of credit secured by a non-owner-occupied rental of one to four units. Debt service coverage ratio (DSCR) means the rent divided by the payment the lender tests. You borrow against the building’s equity, and the building’s income decides whether the line fits.
A standard HELOC works differently. The lender calculates your income, your other debts and your debt-to-income ratio. A DSCR line skips that personal calculation. There is no traditional personal-income documentation: no W-2s or pay stubs. The file still has documents: the lease, the credit report and a valuation of the property. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Duplexes, triplexes and fourplexes fit well. They are residential, they produce several rent streams, and they often carry enough equity to matter. Five or more units is a different product and sits outside this program.
Many banks and credit unions write HELOCs only on a primary home. NerdWallet’s guide to investment-property HELOCs says not all lenders offer them and that qualification is strict. That gap is why investors ask who lends on rentals at all.
How Do Lenders Underwrite It, Step by Step?
Underwriting runs in a fixed order, and a file can stall at any step. Lendmire’s wholesale network follows the same logic across most programs. The figures below are ceilings and floors, never offers, and every one is subject to underwriting.
1. Confirm the property fits. It must be a non-owner-occupied rental. The line is never offered on your own home or a second home. It is never closed together with a purchase, and it is never a third lien.
2. Pick the lien position. If you keep a first mortgage, you can take only a second lien. A first lien exists only on a rental with no mortgage.
3. Check credit. A second lien needs a 720 score. A first lien needs 700. The tier comes from the lender’s own credit report. There can be no 30-day mortgage late in the last 12 months. The program also wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
4. Run the coverage test. Gross monthly rent divided by the qualifying payment must reach 1.10x. The qualifying payment is a fully amortizing payment on the entire credit limit, figured at the starting rate plus two percentage points. Taxes and insurance are not part of it.
5. Count the rent. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser’s figure comes from Form 1007, the rent schedule.
6. Check the lease and vacancy. A lease must be in place. A two-to-four-unit building may have at most one vacant unit.
7. Clear 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).
8. Order the valuation. The path depends on line size, covered below.
On a second lien, the first-mortgage payment raises a fair question. Does it join the qualifying payment? Confirm on the file how the lender treats the first-mortgage payment in the coverage calculation. The lender’s own calculation governs.
What Leverage Can You Reach?
Leverage depends on lien position and score. Second liens are measured by combined loan-to-value (CLTV). That is the first-mortgage balance plus the new line, divided by the property’s value. First liens count only the new line, so they are measured by plain loan-to-value (LTV).
| Structure | Score | Ceiling | Line size |
|---|---|---|---|
| Second lien (first mortgage stays) | 720+ | 70% CLTV | $50,000–$500,000 |
| First lien (rental has no mortgage) | 740+ | 75% LTV | Up to $500,000 |
| First lien (rental has no mortgage) | 700–739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
There is no second-lien tier below 720. A borrower with a first mortgage and a 700–719 score therefore has no second-lien cell to land in. A declining-market flag on the property lowers a ceiling by five percentage points.
Here is why the combined figure matters. Say your first mortgage already uses most of a building’s value. A second lien at 70% CLTV leaves little room, even with strong rent. The line needs equity as well as coverage.
Duplex, Triplex or Fourplex: What Changes?
Unit count changes two things: how much one vacancy hurts, and how much rent backs the test. The program treats all three building types the same. The lease, the market rent and the 1.10x floor apply to each.
The vacancy rule is where unit count bites. A duplex with one vacant unit has half its units unleased. A triplex has a third unleased. A fourplex has a quarter unleased. The rule allows one vacancy in a two-to-four-unit building, but the coverage test feels it very differently. In a duplex, the lease on the occupied unit must carry the whole test. In a fourplex, three leases share the load.
The fix is simple. Lease the vacant unit before you apply, because a signed lease puts that unit’s rent into the test.
Now the worked example (illustrative only, and the lender’s calculation governs). Say a triplex has three leased units, counted at the lesser-of rent. They cover the stress payment at about 1.3x. That clears 1.10x. Now suppose the owner asks for a line twice as large. The payment is sized on the entire limit, so coverage falls to roughly 0.65x. The same building now misses the floor.
A bigger line lowers coverage. Many borrowers expect the opposite. Sizing the line to the coverage the building supports is part of structuring the file.
Mixed-use buildings do not qualify. Neither do commercial properties, land contracts, row homes, condotels or leaseholds. Rural-designated property is also outside the program. So is a property listed for sale in the prior two months, and a property with a solar lien.
How Do the Draws and Repayment Work?
The line is a revolving, open-end line of credit, but this program has a firm structure around it. It has a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
At least 80% of the line must be drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws must be at least $5,000 each.
Plan for that closing draw. You are not opening a large standby line and drawing a sliver. You are taking most of it on day one. Size the line to what you will use, not to the most the equity allows.
Plan for the step-up too. When the draw period ends, the payment includes principal. Model the building’s coverage at that point, not only during the interest-only years.
Where Do the Rules Break?
The general rule is simple: rent qualifies the line. These edge cases are where files get tricky.
You live in one unit. Then the building is owner-occupied, and this line is not offered. A primary-residence HELOC is a different product with different rules. A house-hacker who moves out and leases every unit can revisit the question after the title and seasoning clocks run.
You just bought it. The seasoning rule above applies. A purchase is also never closed together with the line. They are separate transactions.
You just rehabbed it. An automated valuation may not capture fresh renovation value. Lines to $400,000 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 on Form 1004, 1073 or 1025, so the valuation method changes at that amount regardless of the line-size tiers used for leverage. Appraisal waivers are not accepted. A full appraisal is the cleaner path after a major rehab.
An LLC holds title. That is allowed on an investment property, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not be the borrowers on the first mortgage.
The borrower is a foreign national. Foreign nationals and ITIN borrowers are not eligible. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are.
You plan to use the line as a down payment. The purchase lender makes its own decision on borrowed down-payment funds. The new property must also cover its own payment. If you finance an entire purchase with a line, you hold no equity in the new building.
You own several rentals. The program caps exposure at five loans or $2,500,000 per borrower. No reserves and no cash to close are required.
The federal CFPB HELOC brochure is written around a borrower’s own home. That is a useful reminder: a line on a rental is underwritten on the building’s rent, not on a home you live in.
Which Lenders Offer It, and How Does a Broker Shop Them?
Which lenders fit depends on the file. A lender is a fit when its rules match your property type, credit profile, leverage need and documents. The best program for your situation may differ from your neighbor’s.
Lendmire does not rank lenders or name them, and it does not lend. It works with a network of wholesale DSCR HELOC lenders. It reads your scenario, then matches it to the program whose rules fit. A broker sees many guideline sets, so the screening goes faster than calling banks one by one.
Here is what the screening looks at:
- Occupancy. The building must be a pure rental.
- Lien position. Do you keep a first mortgage, or is the rental paid off?
- Credit tier. The 720 and 700 floors sit at the heart of the match.
- Combined leverage. Your first-mortgage balance matters as much as the new line.
- Valuation path. The line size decides between an automated valuation and a full appraisal.
- Property type. Row homes, condotels and mixed-use buildings fall out early.
Prepare the lease or leases, the first-mortgage statement, proof of insurance and the entity documents if an LLC holds title. Lendmire’s piece Top Bank Statement HELOC Providers on a Duplex, Triplex or Fourplex covers the alternative that is reviewed on deposits instead of rent.
This program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Those 15 are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington. If your rental sits elsewhere, a different product may apply.
Second Lien or Cash-Out Refinance?
This is the real investor decision. A second lien leaves your existing first mortgage untouched. That matters when the first loan carries terms you would not get again. A cash-out refinance replaces the first mortgage with a new loan.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Cash structure | Line, 80% drawn at close | One lump sum |
| Best fit | Keep a low first loan | Reset the whole loan |
A HELOC qualified on personal income is a third option. That product calculates your income and debt-to-income ratio, so it suits a borrower with strong paychecks and a thin rental file.
The variable rate and the later principal step-up both affect coverage. A line can look strong during the interest-only years and thin afterward. Run both numbers before you commit. The complete DSCR loans guide covers the broader loan family.
Stacking a second lien on a building also raises your exposure on one asset. Falling behind on either lien puts the property at risk. The CFPB’s explanation of a HELOC describes the same logic for a home: a line you borrow against repeatedly, with the property pledged as security.
Key Terms Defined
DSCR (debt service coverage ratio): The rent divided by the payment the lender tests. This program needs at least 1.10x.
CLTV (combined loan-to-value): The first-mortgage balance plus the new line, divided by the property’s value.
Second lien: A loan that sits behind your first mortgage. If the property is ever sold or foreclosed, the first lien is paid first.
Qualifying payment: The stress payment lenders use for the coverage test. It is a fully amortizing payment on the whole line, figured at the starting rate plus two percentage points.
Seasoning: The waiting period a lender wants after a purchase or refinance before it will lend again.
Draw period: The stretch when you can borrow against the line. On this program it is five years, interest-only on the drawn balance.
Frequently Asked Questions
Can I get a DSCR HELOC if I live in one unit of the duplex?
No. The line is offered only on non-owner-occupied rentals, never on your own home. If you move out and lease every unit, the building can become eligible once the seasoning clocks have run.
How long must I own the property first?
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). Seasoning is measured from the documented dates on the file, not from when you started renting the building.
Does one vacant unit disqualify the building?
Not by itself. A two-to-four-unit property may have at most one vacant unit, and a lease must be in place on the rest. Leasing the vacant unit before you apply puts its rent into the coverage test.
Can an LLC hold title?
Yes, subject to program terms, and only on an investment property. The members sign as guarantors.
How much cash do I have to draw at closing?
At least 80% of the line, and never less than $50,000. On the smallest lines, that means the whole line.
