The Quick Read: The providers that fit a fourplex are the ones that lend a revolving line on a two-to-four-unit, non-owner-occupied rental, qualify it on the building’s rent, and accept an LLC on title. Few lenders do all three, so the right fit depends on your property, credit score, and combined leverage, not on a ranking.
- The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage.
- The rent qualifies it: minimum 1.10x coverage on a stress payment over the whole credit limit, subject to underwriting.
- Combined leverage on a second lien reaches 70% CLTV at a 720 score or better, on lines of $50,000 to $500,000, through select programs.
- At least 80% of the line is drawn at closing, so this works like a flexible loan, not standby cash.
- A two-to-four-unit building may have at most one vacant unit.
What a DSCR HELOC Is (and Is Not)
A DSCR HELOC is a revolving line of credit secured by a rental you own. The lender sizes it on the building’s rent and the equity in it. It does not calculate your personal income.
Think of it as a hybrid. The structure is a normal home equity line: you borrow, repay, and borrow again within a limit. The qualification is a rental-loan idea: does the rent cover the payment? Across Lendmire’s wholesale network, the lenders we work with qualify these lines on that same pattern, and the owner’s tax returns, W-2s, and pay stubs are not part of it. The line qualifies primarily on the rental’s income covering the payment, subject to lender guidelines.
The term “DSCR HELOC” is a market nickname, not a standardized product. Some products sold under that label are closed-end second mortgages that pay out one lump sum. This article describes a true revolving line, and the figures below are the ceilings and floors of select programs, never offers.
One more boundary matters. These are loans on non-owner-occupied investment property. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage. A home equity line on your own residence is a different product, and this one is never offered on an owner-occupied home or a second home.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. At 1.10x, the rent is 10% more than the payment.
Second lien: A loan recorded behind your existing first mortgage. If the property is ever sold or foreclosed, the first mortgage gets paid first.
First lien: A loan in first position. On this program it exists only on a rental with no mortgage.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value. We write first-lien leverage as LTV and second-lien leverage as CLTV.
Qualifying (stress) payment: The payment the lender uses for the coverage test. Here it is a fully amortizing payment on the entire credit limit at a higher test rate, not the payment you will actually make.
Draw period: The stretch when you can borrow from the line and pay interest only on what you drew.
Form 1007: The appraiser’s rent schedule, which estimates the property’s market rent.
How Underwriting Treats a Fourplex, Step by Step
A fourplex is a single financed property with four legal units. Underwriters treat it as residential, not commercial, because commercial lending starts at five units. The review follows a set order, and each step can end the file.
1. Property screen. The lender confirms the building is an eligible one-to-four-unit rental. Rural-designated property, row homes, condotels, mixed-use buildings, and leaseholds fall outside this program.
2. Title and vesting. You can hold title personally or in an LLC, depending on program guidelines. If an LLC holds title, its members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.
3. Lien position. If you keep a first mortgage, the line is a second lien. If the building has no mortgage, it can be a first lien. The line is never closed together with a purchase, and it is never a third lien.
4. Equity sizing. The lender takes a percentage of the property’s value and subtracts what you owe. The CFPB’s HELOC booklet describes that basic method. The leverage tiers below set the percentage.
5. Coverage test. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. That rent is divided by a stress payment on the entire limit. The result must reach 1.10x.
6. Credit and history. The lender pulls its own credit report and checks your mortgage payment history.
7. Valuation. The lender orders an automated valuation or a full appraisal, depending on line size.
Two details on the coverage test surprise first-time borrowers. First, the stress payment covers the full limit, not only the amount you draw. Second, taxes and insurance are not part of that qualifying payment. On a second lien, confirm on the file how the lender treats your first-mortgage payment, because the lender’s own coverage calculation governs.
Who Offers a DSCR HELOC on a Fourplex?
Provider Types, Not a Ranking
No honest ranking exists, because the best program for your situation depends on the building, the credit profile, and how much leverage you need. What you can compare is the type of provider. NerdWallet notes that investment-property lines are not offered by every lender, and that the lender pool is smaller than for a primary home.
| Provider type | Income test | 2–4 units | LLC title |
|---|---|---|---|
| Big banks and large retail lenders | Usually personal income | Often single-family only | Often individuals only |
| Credit unions and community banks | Usually personal income | Varies by lender | Varies by lender |
| Online lenders | Mixed | Varies by lender | Varies by lender |
| Wholesale lenders via a broker | Rent coverage on select programs | Written on select programs | Allowed on select programs |
Those cells are general tendencies, and individual lenders differ. That variation is the reason a broker exists. Lendmire is a mortgage broker, not a lender. It works with a network of wholesale DSCR HELOC lenders and matches your scenario to the program whose rules fit it. The lenders that write a fourplex line depend on your state, your title, and your leverage.
If you hold a fourplex in an LLC, say so at the start. Many programs lend only to individuals, and that one fact removes most of the field before credit is ever pulled.

The Leverage Tiers
Leverage depends on lien position and credit score. These are ceilings through select programs, subject to underwriting, and your file may land lower.
| Lien position | 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 | 720 or better | 65% LTV | Above $500,000, to $1,000,000 |
There is no second-lien tier below a 720 score. A borrower who keeps a first mortgage can only take a second lien, so that 720 floor applies to them. A first lien exists only on a rental with no mortgage, and its floor is 700.
Here is how that plays out in percentages. Say your fourplex has a first mortgage at 50% of value. A second-lien line at the 70% CLTV ceiling could add up to 20% of value on top of it. If the first mortgage sits at 60% of value, the same ceiling leaves only 10% of value. The lender’s declining-market flag can lower the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
The minimum line is $50,000. A modest building with a large first mortgage may not leave room for even that, so run the equity math before you spend money on an appraisal.
Draws, Repayment, and the 80% Closing Draw
The structure is simple but less flexible than most people expect. The draw period lasts 5 years, interest only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
At least 80% of the line is 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 around that. Interest starts on most of the line on day one, so this is not a standby cushion. It works best when you already know where the money is going, such as the down payment on the next rental. A variable rate also means your cost can move, so stress-test the cash flow of both buildings. The CFPB also warns that you could lose the property securing a line if you cannot repay it. On this program that property is your rental.
If you use the proceeds to buy or improve property, tax treatment varies; consult a qualified professional.
The Valuation and the File
Valuation scales with line size. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal on Form 1004, 1073, or 1025. Appraisal waivers are not accepted.
The credit rules are plain. The minimum score is 720 on a second lien and 700 on a first lien, measured on the lender’s own report. The program requires no 30-day mortgage late in the last 12 months. It also requires 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required, subject to underwriting.
Exposure has a cap: at most 5 loans or $2,500,000 per borrower with the program. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Where the Rule Breaks
Most fourplex files that stall do so on one of a handful of edge cases.
You live in one unit. Owner-occupying a unit moves the building into owner-occupied territory, and this line is never offered there. Claiming investor status on a building you occupy is misrepresentation, and it is not worth the risk.
One unit is vacant. A two-to-four-unit property may have at most one vacant unit, and a lease must be in place. A fourplex with two empty units is out until you lease one.
The building is a recent purchase or refinance. 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). Your next-deal timeline should start from those dates.
It is five or more units. That is commercial lending, a different product with different rules.
The building was recently listed. A property listed for sale in the prior two months is ineligible. A solar lien also disqualifies it.
It sits in an excluded category. Mixed-use, condotel, land trust, age-restricted, and leasehold properties fall outside this lane.
The title or the borrower does not fit. Some banks lend only to individuals, which blocks an LLC. This program accepts an LLC as vesting on investment property, subject to program terms. An ITIN or foreign-national borrower is outside it.
Availability. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Those are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia, and Washington.
HELOC or Cash-Out Refinance on the Same Building?
The choice turns on whether your existing first mortgage is worth keeping. A cash-out refinance replaces the whole first mortgage and resets the balance. A line leaves the first mortgage untouched and adds a second lien behind it.
| Factor | DSCR HELOC | Personal-income HELOC on a rental | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Rental income | Owner’s personal income, per that program | Rental income |
| First mortgage | Stays in place (second lien) | Stays in place | Replaced |
| Structure | Revolving line | Revolving line | One closed-end loan |
| Fit | Keep a favorable first | Strong personal income | Reset the whole loan |
The tradeoff is simple. Keep the first mortgage if its terms are favorable and you need a modest amount of equity. Refinance if you want one payment and a fixed structure.
A Fourplex, Worked Through
Run the numbers on a hypothetical fourplex. Treat these as modeled assumptions, not market data, and know that the lender’s own calculation governs.
Suppose the rent used for lender review, set by the lesser-of rule above, divides into the stress payment at 1.12x. That clears the 1.10x minimum, with little room to spare. If the same building tests at 1.05x, it falls short. Because the test runs on the entire limit, a smaller line may be the way to fix the number. Cutting the line size lowers the stress payment and raises coverage.
Now add leverage. If the first mortgage is already high against value, the CLTV ceiling, not coverage, limits the line. If the first mortgage is low, coverage becomes the limit. Buildings with a vacant unit lose an income stream, so the underwriter’s rent figure and your rent roll both matter. Confirm how the lender counts a vacant unit before you apply, because the program’s published rules do not spell that out.
Pre-Application Checklist
- Current first-mortgage statement and payment history
- Leases for every occupied unit, plus three months of rent receipts if a lease exceeds market rent
- LLC documents, if the entity holds title, and the vesting deed
- Insurance declaration, with flood coverage where required
- A schedule of your financed properties
- A realistic line size, with the $50,000 minimum and the 80% closing draw in mind
Then work backward from the use of funds. If the line will fund the next purchase, remember it is never closed together with that purchase, so it needs to be in place before the offer.
Frequently Asked Questions
Can I get a DSCR HELOC on a triplex or fourplex?
Yes, through select programs. The line covers two-to-four-unit rentals that are non-owner-occupied, with at most one vacant unit. Five or more units is commercial lending and falls outside it. Eligibility is subject to underwriting.
Does my LLC have to be removed from title?
No, not on this program. Vesting in your LLC is allowed on investment property, and the members sign as guarantors. Many lenders do require individual title, so confirm that early.
How soon after buying a fourplex can I take a line?
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).
Does the line count against my next purchase?
Yes, it can. The line is a financed obligation, and it appears in your schedule of financed properties and in the exposure cap of 5 loans or $2,500,000 per borrower with the program. How a future lender treats it depends on that lender’s guidelines.
Can I use it on a building where I live in one unit?
No. A building with an owner-occupied unit is owner-occupied property, and this line is never offered there. A pure rental fourplex is the fit.
