The Quick Read: Usually, yes on Lendmire’s wholesale network, as long as the fourplex is held in your own name or a revocable trust, because an investment line there is priced off occupancy and credit rather than unit count, while across the wider market a fourplex often gets fewer lenders and tighter limits. The catch is that an investment line is a narrow product everywhere. Subject to lender guidelines and full file review, here is what to expect:
- An investment-property line tops out at 70% combined loan-to-value (CLTV), with a 700 minimum credit profile.
- The maximum line on an investment property is $500,000.
- A fourplex qualifies as a 1-4 unit residential property. Five or more units is commercial lending, which is a different product.
- LLC-held fourplexes cannot take this line. A DSCR cash-out refinance is the usual route instead.
Why Landlords Assume a Fourplex Gets House Terms
A HELOC is a home equity line of credit: a revolving line secured by a lien on your property. Most advertising for it shows a primary residence. So a landlord with a fourplex reasonably wonders whether the same deal carries over.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Two things get mixed up. The first is the product itself, which is built around a borrower’s personal credit and debt load. The second is the property, which is a four-unit building with four leases. A lender can say yes to one and no to the other.
NerdWallet’s explainer on investment-property HELOCs says you can get one. It also says the lender pool is smaller, you can usually borrow less than against a primary home, and lenders see more default risk. That matches what brokers see in practice. Many lenders simply stop at single-family, or at two units.
Investors report the same thing. A BiggerPockets thread describes a lender who pulled credit and then declined at underwriting because they only did single-family. Another poster found lenders for single-family and two-unit rentals but none for three or four units. The thread is several years old and anecdotal, so treat it as a pattern, not a rule.
So Is the Answer Yes or No?
It depends on which lender you ask. Across the broader market, a fourplex is a harder sell than a house. Across Lendmire’s wholesale network, the investment table is built on occupancy and credit, not on unit count.
Lendmire is a broker. It arranges these lines through select wholesale partners and is never the lender. On those programs, single-family homes, 2-4 unit buildings, PUDs, townhomes and condominiums are all eligible property types. The investment-property ceiling doesn’t change when the unit count goes up.
Here is how the two compare on the same investment line.
| Factor | Single-family rental | Fourplex |
|---|---|---|
| Property eligible? | Yes | Yes, as a 2-4 unit |
| Max CLTV (investment) | 70% | 70% |
| Minimum credit | 700 | 700 |
| Maximum line | $500,000 | $500,000 |
| Title | Individual or revocable trust | Same |
Market surveys tell a different story at the top end. White Coat Investor lists 80% as a typical loan-to-value limit and 720 as a typical credit score for investment-property lines. Those are market-wide figures. On this network, an investment line stops at 70% CLTV with a 700 minimum.
Credit above 700 doesn’t buy more leverage on an investment line. Both the 720 and 700 tiers cap at 70% CLTV. Think of credit as a gate you have to clear, not a dial you can turn up.
What Counts as a Fourplex?
A fourplex is one building with four legal, separate units on one title. That sounds obvious, but it trips people up.
Five units or more is commercial lending. HELOC rules and programs no longer apply, and you move into commercial loan territory.
Mixed-use buildings are not eligible, and neither is agricultural zoning. A fourplex with a corner shop on the ground floor can fail on that point alone. Commercial property in general is off the table for this line.
A single-family home with a rented basement is not a fourplex. Unit status has to be legal and separate. Appraisal guidance treats a one-unit home with an extra unit as a one-unit property, and the same logic applies when a lender reviews yours.
Manufactured homes, co-ops, condotels and log homes are not eligible either.
Why Lenders Treat Four Units Differently
Lenders worry about two things on a 3-4 unit building: how to value it, and who buys the loan.
Valuation is the first. A single-family house is appraised against nearby house sales. A fourplex needs comparable multi-unit sales, which are scarcer. For 2-4 unit buildings, the standard full appraisal form is the Small Residential Income Property Appraisal Report, known as Form 1025 in Fannie Mae’s selling guide. A single-family appraisal uses a different form. That is a contrast point only. HELOC and DSCR products are not agency loans.
On Lendmire’s network, an investment line caps at $500,000, and full appraisals begin only above $500,000. So an investment line is always in the automated-valuation lane. It commonly closes with no traditional appraisal. You can still request a full appraisal if you want one, and a higher CLTV may call for a second valuation.
Investor appetite is the second. Plenty of lenders keep these lines on their own books and set their own property-type policy. If their risk committee drew the line at two units, your credit score won’t move it. Unit-type exclusions are cutoffs, not scores.
Does the Rent Matter on a HELOC?
Less than you’d hope. A HELOC is largely a personal-credit product. It leans on your credit profile, your debt-to-income ratio (DTI), and the equity in the building. On Lendmire’s network, DTI tops out at 50%, and the line is qualified on the interest-only payment calculated on the maximum draw.
Rent supports the story, but it is not the test. That is the sharpest difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Here is the plain-English version of that ratio. DSCR means debt service coverage ratio. It divides the monthly rent by the monthly payment on the property, which lenders call PITIA: principal, interest, taxes, insurance and any association dues. A fourplex with strong rents can clear that test with room to spare. On a HELOC, the same rents might barely register.
This matters most for three kinds of investors:
- Self-employed landlords whose traditional personal-income documentation understates cash flow.
- Portfolio owners with many financed properties.
- Anyone whose personal DTI is already stretched by other debt.
Title and Ownership: Where LLC Owners Hit the Wall
A HELOC lender will generally lend only against property titled in your personal name or in a revocable living trust, meaning a trust you can change or cancel during your lifetime. LLCs, corporations and partnerships cannot hold title. Neither can irrevocable, blind or land trusts.
If your fourplex is already deeded to an LLC, you have two choices. You can change the vesting, which means moving title into your personal name or a qualifying trust. Or you can skip the HELOC and use a DSCR cash-out refinance, which is the usual route for entity-owned rentals, subject to lender program eligibility.
Moving title has its own consequences, including how your first mortgage and insurance treat the change. Read your existing note and talk to your insurance agent and attorney before you move anything.
How Big a Line Can You Actually Get?
Take the value, apply the CLTV ceiling, and subtract what you already owe. Then check the result against the $500,000 cap.
The formula: value × CLTV limit − first mortgage balance = most you could have available.
Run the numbers on a modeled fourplex. Say your first mortgage sits at 50% of the building’s value. The investment ceiling is 70% CLTV. That leaves room for a line worth up to 20% of the value, subject to credit approval, lender guidelines and the $500,000 cap. If your first mortgage is already near 65%, there is very little room left.
Two more limits can bind before the math does. A borrower can hold only three lines. And an investor who owns more than 15 financed properties is not eligible. Both are checked across the whole portfolio, not property by property.
How the Line Works After Closing
The structure is simple but unforgiving. A second lien means it sits behind your existing first mortgage.
- Draw period: five years of interest-only payments.
- Repayment: 25 years, fully amortizing, which means principal and interest both get paid down.
- Draw at closing: at least 75% of the line is drawn at closing.
- Pricing: it floats through both the draw and repayment periods. It never converts to fixed.
- Later draws: minimums for subsequent draws vary by program and state.
Compare that with the market pattern NerdWallet describes: roughly a 10-year draw period followed by repayment of up to 20 years. That is a generic market description, not this network’s structure. A quoted figure always carries its own program’s draw and repayment terms, so compare like with like.
The 75% draw at closing is the detail that surprises people. A HELOC is usually pitched as a line you keep open and use only when needed. On this network, most of it is borrowed on day one. If you want a standby line with a zero balance, this isn’t that product.
The line also keeps your first mortgage in place. That helps if your existing first mortgage is a good one you don’t want to disturb. Adding a junior lien still deserves a read of your existing note first.
Where Lines Are Offered (and Where They Aren’t)
Lendmire’s HELOC availability is narrower than its DSCR footprint. The DSCR programs cover 41 markets, including Washington, D.C. The HELOC programs run only in the 16 states where Lendmire offers full-service mortgage lending. If you’re outside them, the question is moot and the DSCR path is the real answer.
When a DSCR Cash-Out Beats the HELOC on a Fourplex
Many landlords with a fourplex find the HELOC is the wrong tool. The line is capped, the leverage is 70% CLTV, the pool of lenders is thin, and the rate floats. A DSCR cash-out refinance replaces your first mortgage with a new one and puts the equity in your pocket.
Here is how the two compare for an investor weighing them.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Underwritten on | Personal credit and DTI | Property rent vs. payment |
| Max leverage | 70% CLTV | Around 75% LTV, standard rental |
| Entity title (LLC) | Not allowed | Possible, per program terms |
| Maximum size | $500,000 | up to $3,000,000 on standard programs (smaller balances available through select lenders) |
| First mortgage | Stays in place | Replaced |
On the cash-out side, most programs across the network top out around 75% LTV, with about six months of seasoning as the common expectation. Seasoning is the waiting period between buying a property and refinancing it. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures.
On coverage, 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path goes below 1.00, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
Credit works differently here as well. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Reserves vary by lender, leverage, loan size and transaction type, commonly around six months of PITIA. Conservative files at modest leverage can see reserves waived.
One caution. Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses all sit outside the calculation.
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. The complete DSCR loans guide walks through how the ratio, leverage and credit tiers fit together.
If you want to compare how the equity is released on a rental versus a home, Lendmire’s piece on rental HELOC versus home HELOC equity released covers it.
What About a House-Hack Fourplex?
If you live in one unit, you are in a different category. The building is partly your primary residence, and lenders usually treat that more favorably than a fully rented building. The occupancy tiers on this network are different too. A primary residence can reach a higher CLTV than an investment line, and the 90% ceiling exists only at a 720-or-better credit profile.
Once you move out and rent all four units, the building is an investment property again. The investment limits apply to it from then on. That is the point where many owners shift to a DSCR product.
Four Questions to Ask Before Any Credit Pull
A hard credit pull that ends in a decline at underwriting is a real cost. These questions save you from it.
1. Do you lend on 3-4 unit rentals, or only on single-family and duplexes?
2. What is your CLTV ceiling for non-owner-occupied properties?
3. Do you accept title in a revocable trust, and do you refuse LLCs outright?
4. How much of the line gets drawn at closing, and does the pricing float?
Gather your leases, mortgage statements, proof of reserves and insurance before you apply. Have a plan ready for what you’ll do if the answer to the first question is no.
Federal Rules and Tax: Short Version
Federal disclosure rules require lenders to give HELOC applicants a consumer booklet, according to the CFPB’s compliance page. Those rules cover disclosures. They don’t say whether a lender must offer a line on a fourplex, so unit-count policy is each lender’s own call.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and pay interest only.
Vesting: How title is held, such as an individual or a revocable trust.
Automated valuation: A computer-based value estimate used instead of a traditional appraisal.
DSCR: The monthly rent divided by the monthly PITIA payment.
PITIA: Principal, interest, taxes, insurance and any association dues.
Frequently Asked Questions
Does a vacant unit hurt my chances on a fourplex HELOC?
It can matter, because the lender reviews your whole credit and debt picture, and a vacancy affects the story you’re telling about the building. On a HELOC, rent is supporting information rather than the qualifying test. Vacancy hurts far more on a DSCR loan, where the rent-to-payment ratio is the core of the file.
Can I get a HELOC on a building with five or more units?
No. Five or more units is commercial, and commercial property is not eligible for this line. That is a different loan category with its own underwriting. A true fourplex stays in the 1-4 unit residential lane.
Will a higher credit score get me more leverage on a fourplex?
Not on an investment line. The 720 and 700 tiers both reach 70% CLTV, and 700 is a hard floor with no tier below it. Credit above that threshold buys eligibility, not leverage. The strongest files clear two tests at once: enough equity and enough credit strength.
My fourplex is in an LLC. What are my options?
A HELOC on this network can’t be written to an LLC, corporation or partnership. You can change the vesting to your personal name or a qualifying revocable trust, or you can use a DSCR cash-out refinance. Whether the entity can borrow depends on lender program eligibility and full file review.
Is a HELOC always cheaper than refinancing?
Not always. It depends on your existing first mortgage, how much you need, and the lender’s terms. A HELOC keeps your first mortgage intact, which is valuable if that loan is a good one. A DSCR cash-out replaces it, but it can give you more leverage and a larger amount.
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. You can also call 828-256-2183 to talk through whether the line or a DSCR cash-out fits your fourplex.
Most landlords find the unit count matters less to the answer than the name on the title, so check that first.
