The Quick Read: Yes, through select programs, a duplex, triplex or fourplex can secure a DSCR HELOC, and the unit count inside the 2-4 range does not change the terms. The line qualifies primarily on the building’s rental income covering the payment, subject to lender guidelines. It is written as a standalone second lien behind your first mortgage, or as a first lien on a paid-off rental.
- Duplexes, triplexes and fourplexes share one set of terms on this program.
- Minimum coverage is 1.10x, tested on a stress payment over the entire line.
- A second lien reaches 70% combined loan-to-value at a 720 score or better, subject to underwriting.
- A first lien on a paid-off rental reaches 75% at 740 or better.
- Your LLC can stay on title, and the program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What Does “DSCR HELOC” Actually Mean?
A DSCR HELOC is a revolving line of credit secured by a rental you own, qualified on the property’s rent instead of your personal income. DSCR stands for debt service coverage ratio: monthly rent divided by the monthly payment the lender tests against.
No regulator defines the term. It is market shorthand, and people use it for different products. Some mean a rent-tested cash-out refinance. Others mean an investment HELOC underwritten on the borrower’s income and credit. Some mean the real thing: a line tested on rent.
That last version exists, but it is narrow. The line is a standalone second lien behind a first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never a third lien. It is never closed together with a purchase. It is never a line on your own home.
Two terms help here. A second lien is a loan that sits behind your first mortgage and gets repaid after it. CLTV (combined loan-to-value) is your first mortgage balance plus the new line, divided by the property’s value.
The FTC describes a HELOC as revolving credit secured by the property. That part does not change on a rental.
Are Duplexes, Triplexes and Fourplexes Eligible?
Yes. Two-to-four unit buildings are standard eligible collateral on this program, and all three share one leverage table. A duplex does not get better terms than a fourplex, and a fourplex does not get worse ones.
Where lenders differ is willingness. Across the wholesale network, some lenders will not touch rentals at all. Others take duplexes but balk at three or four units. NerdWallet notes that investment-property HELOCs come with a smaller lender pool and lower borrowing amounts than lines on a primary home, because lenders see higher default risk. Your regular bank saying no tells you about that bank, not about your building.
Four units or fewer is residential lending. Five or more is commercial, which is a different product entirely.
Some property types sit outside this lane:
- Mixed-use buildings and commercial or agricultural property
- Rural-designated property
- Row homes, condotels and leaseholds
- Land trusts and age-restricted communities
- Properties listed for sale in the prior two months
- Properties with a solar lien
What Does Each Building Look Like on Paper?
The coverage test divides all the rent by one payment, so more units usually means a stronger ratio. That is the quiet advantage of small multifamily.
| Factor | Duplex | Triplex | Fourplex |
|---|---|---|---|
| Program terms | Same table | Same table | Same table |
| Share of rent lost per vacant unit | About half | About a third | About a quarter |
| Vacant units allowed | 1 | 1 | 1 |
| Valuation | Full appraisal or AVM path | Same | Same |
| Lender willingness | Widest | Narrower | Narrowest |
The vacancy row matters more than it looks. Under this program, a 2-4 unit building may have at most one vacant unit. In a duplex, that one empty unit removes half your rent roll and likely sinks the ratio. In a fourplex, it removes a quarter. Run the math with a vacant unit before you apply, not after.
How Does the Coverage Test Work on a Multi-Unit Building?
The line qualifies when gross monthly rent divided by the qualifying payment reaches at least 1.10x. The qualifying payment is not what you will actually pay. It is a fully amortizing payment on the entire credit limit at a stressed rate, which is the start rate plus two percentage points. The lender runs it on the whole line even if you draw less.
Rent counts as the lesser of two numbers: the appraiser’s market rent (from Form 1007, a rent schedule) or the lease. A lease above market does not raise the counted rent; the lower figure governs. A lease in place is required.
Picture a fourplex where all four units are leased near market. Combined rent sits well above a stressed payment on a mid-sized line, so the coverage clears 1.10x with room. Now picture the same building with one unit empty. The rent drops by a quarter and the ratio can slip under the floor. Same building, same line, different answer.
How the existing first mortgage payment enters the test on a second lien is a lender-level calculation, and the lender’s own coverage math governs. Do not assume it is included or excluded.
One more trap. Clearing 1.10x proves the rent supports the line. It does not prove the property cash-flows after taxes, insurance, repairs and your first mortgage. Every loan stacked on a building adds another payment to the same rent roll.
What Leverage Can You Reach?
Leverage depends on lien position and credit score, subject to underwriting.
| Structure | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
Below 720, there is no second-lien option on this program. A first lien starts at 700. The credit tier comes from the lender’s own report.
Run a quick example. Say your fourplex is worth a figure you and the appraiser agree on, and your first mortgage already covers a large share of it. A 70% CLTV ceiling means the first mortgage plus the new line cannot pass 70% of value. If the first mortgage is already near that mark, the room left for a line may be too small to matter. A paid-off rental has the most room, up to 75% LTV at the top tier.
Credit history matters beyond the score. Expect no 30-day mortgage late in the last 12 months. Expect 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
How Do Draws and Repayment Work?
The line has a 5-year draw period, interest-only on what you have drawn. Then comes a 25-year repayment period where the balance fully amortizes, for a 30-year maturity. The rate is variable.
Two draw rules surprise people. At least 80% of the line, and never less than $50,000, must be drawn at closing. Later draws are at least $5,000 each. This is not a standby line you open and leave at zero. It is closer to a loan with a revolving tail.
Payment shock is the real risk. When the draw period ends, the payment steps up as principal begins. The CFPB also warns that a lender can reduce or freeze a line if the property’s value falls significantly, and that you could lose the property if you cannot repay. Plan around both.
What About LLC Title and Living in One Unit?
Your LLC can stay on title, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The people on the line do not have to be the same people on the first mortgage.
Occupancy is the hard stop. This line is for non-owner-occupied rentals. If you live in one unit of your duplex, it is not eligible. That is the house-hacker’s problem: a lender may treat the building as your primary residence, which is a different product. Once you move out and rent every unit, the building becomes a candidate. DSCR loans are designed for non-owner-occupied investment properties, and because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
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 on this program.
What Does the File Look Like?
Honestly, the file is lighter than a bank’s. No traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income calculation, subject to lender guidelines. No reserves and no cash to close are required. But the rent, the lease, the credit report and the valuation are all documented. This is not a no-paper loan.
Here is what to expect:
1. Credit report. The lender’s own pull sets your tier.
2. Lease and rent schedule. Leases for each occupied unit, plus the appraiser’s market rent.
3. 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.
4. Title and vesting. A full title policy on a first lien and on larger second liens. Smaller second liens use an owner-and-encumbrance report.
5. Insurance. Hazard coverage for both liens, plus flood coverage where required.
6. 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).
Exposure caps apply too: at most 5 loans or $2,500,000 per borrower with the program. Lenders also adjust for market conditions, so a declining-market flag can trim the ceiling by 5 points.
Multi-unit comps are scarcer than single-family comps, so valuations can be harder to support. A tight appraisal is the most common place a fourplex file loses leverage.
Which Product Fits Your Building?
Most investors who search for this end up choosing between a DSCR HELOC and a DSCR cash-out refinance. A cash-out refinance is a closed-end loan that replaces your first mortgage and pays you a lump sum.
Short version:
- Keep the line if your first mortgage is cheap and you want to leave it alone, you want staged draws, or you hold the building in an LLC.
- Choose the cash-out if you need a larger lump sum or want a fixed-term structure, and replacing the first mortgage costs you little.
- Consider a borrower-underwritten investment HELOC if your personal income is strong and your rent coverage is thin. That product is tested on you, not the rent, and its rules differ from this program’s.
If your coverage falls short of this line’s 1.10x minimum, ask about structure before you give up. Some DSCR cash-out refinance programs in the network review lower coverage, but usually with lower leverage, stronger compensating factors or different pricing. Those are different products, not exceptions to this line’s test.
Across the wholesale network, the honest answer for many 3-4 unit owners is that the building qualifies and the lender pool is the real filter. A broker who sees many guideline sheets can route you past the lenders that decline small multifamily. The complete DSCR loans guide explains how these programs fit together, and Lendmire’s piece DSCR HELOC vs. DSCR Cash-Out Refinance on a Duplex, Triplex or Fourplex walks through the choice in more depth.
What Can You Use the Money For?
Many investors use a line like this for the next down payment, a renovation, or repositioning a unit. A line on one building does not erase the down payment, reserve or source-of-funds rules on the purchase loan for the next one, so ask that lender early.
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.

Form 1007: the appraiser’s rent schedule that supports market rent.
Frequently Asked Questions
Can I get a DSCR HELOC on a fourplex?
Yes, through select programs. A fourplex shares the same leverage table as a duplex and triplex: up to 70% CLTV on a second lien at a 720 score or better, subject to underwriting. The harder part is finding a lender that accepts three or four units at all.
Can I live in one unit and still qualify?
No. This line is for non-owner-occupied rentals only. Live in one unit and a lender may treat the building as a primary residence. After you move out and rent every unit, the property becomes a candidate.
Does a fourplex need commercial financing?
No. Four units or fewer is residential. Five or more is commercial, which is a different product and outside this program.
What if the building is held in an LLC?
It can stay in the LLC, subject to program terms. Members sign as guarantors, and any title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Does rent from every unit count, and what if one is empty?
Rent from occupied units counts, using the lesser of market rent or the lease. A 2-4 unit building may have at most one vacant unit. One empty unit can cut the ratio sharply, especially in a duplex.
