The Quick Read: A DSCR HELOC on a fourplex qualifies primarily on the building’s rental income covering a stress payment on the whole credit line, subject to lender guidelines, so your other financed rentals are not a test of their own. The fourplex counts as one property, needs a lease in place, and must clear 1.10x coverage. Everything below is 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 fourplex is one property with one rent roll, not four properties.
- Coverage is gross monthly rent divided by a stress payment on the entire credit limit, with a minimum of 1.10x.
- Your credit score, mortgage history and the valuation matter as much as the rent.
- The program caps exposure per borrower at 5 loans or $2,500,000 with the program, which is different from owning five financed rentals.
What Is a DSCR HELOC on a Rental?
A DSCR HELOC is a revolving line of credit secured by a rental you keep, sized on the rent instead of your paycheck. DSCR stands for debt service coverage ratio, which compares the property’s income to its debt payment. A HELOC is a home equity line of credit, meaning you borrow against equity, repay, and borrow again within set rules.
The formula is simple: gross monthly rent divided by the qualifying payment. A result above 1.00x means rent exceeds the payment. On the program described here, the minimum is 1.10x, and that requirement applies to select programs in Lendmire’s wholesale network.
The label is informal. Across the network, “DSCR HELOC” describes several products with different lien positions and leverage limits. This article walks through one structure in detail so you can compare it against others.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Does a Fourplex Count as One Property or Four?
A fourplex counts as one property. It has one deed, one parcel of collateral and one rent roll, even though four households live there. The lender tests the building as a single file.
| Item | How it counts |
|---|---|
| The building | One property |
| The four units | One rent roll, tested together |
| The first mortgage | One lien already on the building |
| The new line | One standalone lien, one building |
This matters because a fourplex is also not “five units,” and it is not a commercial building. A two-to-four-unit residential property is eligible for the program. Five or more units is a different product entirely.
The appraisal reports rent unit by unit. According to the Fannie Mae Selling Guide, Form 1025 is the report for two- to four-unit properties, while Form 1007 is the rent schedule tied to one-unit investment properties. An appraisal-industry explainer adds that the 1025 covers unit mix, market value and rental income, and that a rent roll with several different rates may call for a separate rent schedule addendum. Fannie Mae is cited here for form names only. It does not set the rules for this program.
Do Five Financed Rentals Stop You?
Owning five financed rentals does not block this line by itself. The lender tests the subject property’s rent against the stress payment on the subject line. It does not calculate your income or a debt-to-income ratio, and it does not total up your other mortgages against your paycheck.
Other lanes behave differently. Agency loans count your financed properties and cap them, and retail banks often apply their own internal property limits. A BiggerPockets Rookie Reply episode discusses how many banks do not give HELOCs on rentals, and a listener adds that none offer them on rentals that still carry a mortgage. If you have hit a wall at a large retail lender, that wall may not exist in a rent-qualified program.
Here is the catch. This program limits each borrower to at most 5 loans or $2,500,000 with the program itself. That limit counts loans placed with this program, not every mortgage you hold elsewhere. Still, if you already carry several loans with it, ask early how the new line fits inside that cap.
Your other four rentals matter indirectly. They show up in your credit report, and a late payment on any mortgage can break the history rule described below.
How Does the Lender Test the Fourplex, Step by Step?
The lender runs the file in a fixed order. You can run the same screen yourself before you apply.
1. Eligibility. The building must be a non-owner-occupied rental. The borrower must be a US citizen, a permanent resident, or a non-permanent resident with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
2. Lien position. If you keep a first mortgage, the line is a standalone second lien. If the building has no mortgage, it can be a standalone first lien. It is never closed together with a purchase and never sits in third position.
3. Rent. 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 in place is required, and a two-to-four-unit property may have at most 1 vacant unit.
4. Qualifying payment. The payment is principal and interest on the entire credit limit, calculated at a higher stress level than the line’s starting payment. Taxes and insurance are not part of it. Confirm on the file how the lender treats the first-mortgage payment on a second lien, because the lender’s coverage calculation governs.
5. Coverage. Divide gross monthly rent by that payment. You need at least 1.10x.
6. Combined leverage. On a second lien, the first mortgage balance plus the new line, divided by value, is combined loan-to-value (CLTV). The cap is 70% CLTV at a 720 credit score or better, on lines from $50,000 up to $500,000.
7. Credit and history. The lender’s own credit report sets the tier. The mortgage history must show no 30-day late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed in lieu.
Because the payment is stressed on the full line, size the request carefully. A smaller line can lift coverage on a building that clears 1.10x only narrowly.
A Worked Example With Ratios
Treat these numbers as illustrative only, since the lender’s own calculation governs. Assume your four units carry similar rents and the whole building clears about 1.5x on the stress payment. All four units are leased, so the file clears 1.10x with room to spare.
Now assume one unit goes vacant. The program allows 1 vacant unit in a two-to-four-unit building, and coverage on the three leased units lands near 1.1x if the vacant unit contributes no rent. That sits right at the floor, so a slightly lower appraisal rent or a larger line could tip the file below it. Ask how the lender treats a vacant unit before you assume the building passes.
How Does Seasoning Work on a Rental You Just Bought?
Seasoning is the waiting period between a purchase or refinance and the new line. 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).
Check each of your financed rentals against these clocks if you plan to use more than one in your strategy. A building you refinanced recently may be out of reach, even if the rent and equity look strong.
A Five-Rental Walkthrough
Picture five files, each judged on its own. The table shows how each could land under this program. These are illustrative situations, and each is subject to underwriting.
| Property | Situation | Likely route |
|---|---|---|
| Fourplex | Mortgaged, 12 months on title | Second-lien line, tested on its own rent |
| Rental B | Free and clear | First-lien line, tested on its own rent |
| Rental C | Bought 3 months ago | Wait out the six-month clocks |
| Rental D | Rural-designated | Outside this program |
| Rental E | Mixed-use building | Outside this program |
Equity in one building cannot support a line on another. Each line secures one property, and each property needs its own rent, lease and valuation. A blanket structure across several buildings exists in the market, but it is a different product.
Where Does the General Rule Break?
The rule says rent qualifies the line. Several edge cases change that answer.
Ineligible building types. The program does not cover rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular or log homes, land contracts, or mixed-use buildings. A fourplex with a commercial storefront is a mixed-use building, so the commercial income never enters the picture. A property listed for sale in the prior 2 months, or one with a solar lien, is also out.
A light appraisal. If the appraised rent comes in below the lease, the lesser figure governs, unless three months of rent receipts support a lease above market. Some lenders in the network review sub-1.00 options on other products, with leverage and terms adjusted, but this line starts at 1.10x.
Declining markets. A declining-market flag lowers the leverage ceiling by 5 points, so the 70% CLTV cap would be reduced accordingly.
LLC title. Vesting in the owner’s LLC is allowed on investment property, 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.
Lower scores. Below 720 there is no second-lien option at all. A borrower at 700 to 719 who keeps a first mortgage cannot take this second-lien line, because the 720 minimum is the floor for a second lien.
First-lien limits. A first lien exists only on a rental with no mortgage. It reaches 75% loan-to-value (LTV) at 740 or better and 70% from 700 to 739 on lines up to $500,000. Lines above that, up to $1,000,000, are capped at 65% LTV at 720 or better. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Payment change. The rate is variable. The line is interest-only on the drawn balance for a 5-year draw period, then moves to a 25-year fully amortizing repayment period within a 30-year maturity. The CFPB’s HELOC booklet defines a HELOC as a loan secured by your property and warns that falling behind could put that property at risk. On a rental, the collateral at risk is the building.
What Do Draws and Valuation Look Like?
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 are at least $5,000 each. This is not a standby reserve you leave mostly untouched.
For valuation, 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. No reserves and no cash to close are required, subject to underwriting.
DSCR HELOC or Cash-Out Refinance?
The choice comes down to whether your current first mortgage is worth keeping. A line behind it leaves that loan untouched. A cash-out refinance replaces it.
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Structure | Revolving line, variable rate | Fixed-amount new loan |
| Best fit | Keeping a strong first mortgage | Resetting the whole loan |
Both are different programs with their own rules.
Remember what this line is not. It is not a purchase loan, and it cannot close with one. The line must already exist before you go under contract on the next rental. Treat the proceeds as a down payment source for a business-purpose purchase. The purchase loan itself is judged mostly on the new property’s own rent.
What Should You Gather Before You Apply?
Build one folder per property. For the fourplex, collect:
- Leases for every occupied unit and three months of rent receipts, if any lease exceeds market rent
- The first-mortgage payoff statement and a check of the note for any junior-lien restriction
- Hazard insurance covering both liens, plus flood coverage where required
- Entity documents and signature authority if the LLC holds title
- A schedule of your other financed rentals, with lender, balance and payment history
Keep in mind that the rent, the lease, the credit report and the valuation are all documented. The program skips traditional personal-income documentation, W-2s and a personal income calculation, subject to lender guidelines. It does not skip paperwork.

Frequently Asked Questions
Does a fourplex count as four loans?
No. A fourplex is one property with one collateral parcel and one rent roll. The new line adds one lien on that building. Whether it counts toward the 5-loan program cap depends on how many loans you already hold with the program.
Does owning more rentals disqualify me?
Not by itself. Qualification runs primarily on the subject property’s rent covering the stress payment, subject to lender guidelines. Your other rentals matter through your credit report, your mortgage history and the program’s exposure cap.
Can the LLC stay on title?
Yes, on investment property, subject to program terms. The LLC’s 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.
How long do I have to own the fourplex?
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 a vacant unit disqualify the building?
Not automatically. A two-to-four-unit property may have at most 1 vacant unit, and a lease must be in place. The real test is whether rent from the leased units still clears 1.10x on the stress payment, subject to underwriting.
