The Quick Read: No single ranked list answers this, because the lenders that write a rent-qualified line on a two-to-four-unit building depend on the property, the lien position, the credit score and how title is held. Lendmire is a mortgage broker, not a lender, and it matches each file to a program in its wholesale network. The program parameters below come from select programs in that network and are subject to underwriting.
- 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 building’s total rent qualifies it, tested at a minimum 1.10x on a stress payment over the whole line.
- Leverage tops out at 70% CLTV on a second lien and at 75% LTV on a first lien.
- Duplexes, triplexes and fourplexes are all eligible, with at most one vacant unit.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
A fourplex is easy to describe and hard to finance on a revolving basis. Most lenders that talk about equity lines are thinking about a borrower’s own home. A line on a rental, sized on rent, is a different file. Lendmire’s complete DSCR loans guide covers the broader family of investor loans.
Why a Ranked List Doesn’t Work Here
Any list of top providers would age badly and mislead. Which lender fits depends on four things: the unit count, whether a first mortgage stays in place, the credit tier, and whether an LLC holds title. A program that suits a free-and-clear triplex in an LLC may not suit a fourplex with a first mortgage held personally.
A broker that shops several wholesale lenders can match the scenario to the program instead of asking you to fit a single lender’s box. That’s the practical advantage. The best program for your situation is the one whose limits, valuation path and title rules line up with your building. Skip any page that names a winner without asking about your lien position.
What a DSCR HELOC Is
A DSCR HELOC is a revolving line secured by a rental you already own, sized on the rent instead of your paycheck. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, up to a limit, during a draw period. A repayment period follows.
“DSCR HELOC” is a market label, not a regulatory category. In Lendmire’s network the structure looks like this:
- A standalone second lien behind your first mortgage, or a standalone first lien on a rental with no mortgage.
- Never closed with a purchase, never a third lien, never a line on your own home.
- The rent qualifies the file: no traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio, subject to lender guidelines.
- The owner’s LLC can hold title (investment property only). Members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Property-level income carries the review. Credit, leverage, valuation and title still decide the outcome.
How Underwriting Treats a 2-4 Unit Building, Step by Step
Underwriting moves through six gates, and a building must clear each one. Failing any gate ends the file, whatever the others show.
1. Collateral. The rental must be non-owner-occupied. A fourplex where you live in one unit is a primary-residence file and a different product.
2. 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).
3. Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted. For a two-to-four-unit building, the full report is typically the Small Residential Income Property Appraisal Report, Form 1025, which covers two- to four-unit properties.
4. Coverage. Monthly rent from the whole building is divided by the qualifying payment.
5. Leverage. Combined loan-to-value is tested against the tier your credit score earns.
6. Credit and title. The lender’s own credit report sets the tier, and vesting and property-type exclusions are reviewed.
The building is one collateral property with one line. Units don’t qualify separately. You also need a lease in place, and at most one unit may be vacant.
How the coverage test counts 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 Form 1007 market rent is the reference point. For a multi-unit building, expect the lender to look at the total across units.
The qualifying payment is the odd part. It is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. That’s a stress payment, and it covers the whole line, not the balance you’ve drawn. Taxes and insurance are not part of it. The minimum coverage is 1.10x.
For a second lien, confirm on the file how the lender treats the first-mortgage payment, because the lender’s own coverage calculation governs. Treat any worked arithmetic as illustrative only.
Unit Count: What Changes From Duplex to Fourplex
The program accepts all three building types, but they behave differently under the same test. A larger building spreads vacancy risk across more leases, while valuation gets harder as comparable sales thin out.
| Factor | Duplex | Triplex | Fourplex |
|---|---|---|---|
| Rent counted | Both units | All three | All four |
| Vacancy allowed | 1 unit | 1 unit | 1 unit |
| Valuation form | 1025 | 1025 | 1025 |
| Lien options | 1st or 2nd | 1st or 2nd | 1st or 2nd |
One vacant unit is the same allowance everywhere, but it hits a duplex hardest. Half the building sits empty, and the lease-in-place requirement still has to be met by the occupied unit. On a fourplex, one empty door leaves three producing rents carrying the full test. That spreads the vacancy across more leases, though it is a structural point, not a promise on any given file.
Think about a modeled fourplex with all four doors leased and rent comfortably above the stress payment. It might clear the 1.10x test with room to spare, and then leverage becomes the real question. Now model a duplex with one door empty. The same test applies, but only one rent is producing. Any scenario like this is illustrative, and the lender’s own calculation governs.
Leverage: Where Most 2-4 Unit Files Actually Get Decided
The tiers depend on lien position and credit score, and all are subject to underwriting.
| 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 | $500,000 to $1,000,000 |
CLTV means the first-mortgage balance plus the new line, divided by value. A second lien has a floor of 720, with no tier below it. A borrower who keeps a first mortgage can only take a second lien, so a score of 700-719 falls short of that floor. A first lien exists only on a rental with no mortgage.
A declining-market flag lowers the ceiling by 5 points. Separately, Philadelphia lines carry a ceiling 10 points lower. On a duplex in a softening submarket, check whether either adjustment applies before you count on the table’s figures.
Here’s the tradeoff. If you hold a low-cost first mortgage you’d rather not disturb, the second-lien line keeps it in place. The CFPB notes that a HELOC sits alongside an existing first mortgage. A cash-out refinance replaces it. If the building has no mortgage, a first-lien line might make sense, but a cash-out refinance can fit better when you want a fixed, one-time payout.
Draw Rules, Terms and Credit
The structure is a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable.
- Lines vary by scenario.
- At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, the whole line is drawn at closing.
- Later draws are at least $5,000 each.
- This is not a standby reserve. A large initial draw is part of the design.
Credit minimums are 720 on a second lien and 700 on a first lien. The program checks for no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
A HELOC is generally due in full if you sell the property. Plan the exit before you draw.
Where the Rules Break
A few situations catch investors who assume a 2-4 unit rental behaves like a single-family one.
- Owner-occupied 2-4 units. Living in one unit of a fourplex makes it a primary-residence file. This line is never offered on an owner-occupied home.
- Two products, one label. An investment-property HELOC qualified on personal income is a separate program with its own credit and debt-load rules. Don’t blend its numbers with the rent-qualified line.
- LLC title. The rent-qualified line allows LLC vesting, subject to lender program eligibility. Don’t assume a personally underwritten HELOC does too.
- Ineligible property types. Rural-designated property, row homes, condotels, mixed-use, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes and land contracts are outside this lane. So is a property listed for sale in the prior 2 months, or one with a solar lien.
- Five or more units. That’s commercial, a different product altogether.
- Closed-end seconds sold as HELOCs. Check that the line actually revolves. This one does, with draws of at least $5,000 after closing.
- Borrower status. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Choosing a Provider Without a Ranking
Because the lenders that write this depend on the file, a short checklist beats a list of names. When a broker shops your scenario, these are the points that sort programs:
- Does the program accept your unit count and property type, including PUD and townhome edges?
- Does it write a second lien, a first lien, or both?
- Will it take an LLC on title, and how does it handle guarantors?
- What is the valuation path at your line size, and what is the automated-valuation threshold?
- Does the program’s footprint include your property’s state?
- How does the lender treat the first-mortgage payment in its coverage calculation on a second lien?
- What are the draw-at-closing and minimum-draw rules?
Prepare the lease or leases, rent receipts if a lease sits above market, the first-mortgage statement, entity documents if an LLC holds title, and proof of title. Your rent, credit report and valuation are all documented, and the rent takes the place of personal-income paperwork.

Frequently Asked Questions
Can a DSCR HELOC go on a duplex, triplex or fourplex?
Yes, through select programs. Two-to-four-unit buildings are eligible, with at most one vacant unit and a lease in place. The line must be a standalone second or first lien on a non-owner-occupied rental, subject to underwriting.
How does the lender seasoning work on a recent purchase?
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). A recent purchase therefore waits out both before it can be considered.
Does the coverage test use my drawn balance?
No. The qualifying payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. A small draw doesn’t shrink the test, and the lender’s own calculation governs.
Can my LLC hold title?
Yes, on this rent-qualified line, subject to program terms. Members sign as guarantors, and a title holder who isn’t a borrower signs a non-borrowing owner acknowledgment and the security instrument.
What if I live in one of the units?
Then it’s a different file. An owner-occupied fourplex is treated as a primary residence, and this line is never offered on an owner-occupied home. Check whether a personally underwritten product fits instead.
