The Quick Read: It depends on three things. You need to hold the property in your own name, carry strong personal credit and low debt, and want a modest amount of cash. When any of those fails, a DSCR cash-out refinance usually fits better, because it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- A HELOC is underwritten on you, not on the rental’s rent.
- Across our wholesale network, an investment-property line tops out at 70% combined loan-to-value and $500,000.
- An LLC cannot hold title on these lines.
- The payment floats and never converts to a fixed payment.
- A DSCR cash-out refinance replaces the first loan. A HELOC sits on top of it.
What a HELOC Does on a Rental
A HELOC is a home equity line of credit. It is a revolving loan secured by property, so you borrow, repay, and borrow again within a limit. Think of it as a credit card with a lien attached.
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.
Lenders size the line with a simple formula. They take a percentage of the property’s value and subtract what you already owe. The result is the room you have left.
Combined loan-to-value (CLTV) is that percentage. It counts the first mortgage and the new line together, as a share of value. If your first mortgage already equals 60% of value, a 70% CLTV ceiling leaves only 10% of value to borrow against.
HELOCs on rentals are less common than HELOCs on a home you live in. NerdWallet says an investment-property HELOC is possible but not offered by all lenders, with strict qualification requirements and limited availability. Big banks that market lines on owner-occupied homes often have no product for a rental.
The standard market structure has two phases. NerdWallet describes a typical 10-year draw period with interest-only payments at a variable cost. Principal and interest repayment then follows, typically up to 20 years.
The network we place files with uses a different shape on investment lines. It runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The pricing floats through both phases and never converts to fixed.
Two Ways to Use One: The Rental or Your Home
The first question is which property secures the line. The two routes behave very differently.
| Factor | Line on the rental | Line on your primary home |
|---|---|---|
| Collateral at risk | The rental | The home you live in |
| Availability | Limited | Wider |
| Title | Your name or a revocable trust | Your name or a revocable trust |
| Network CLTV ceiling | 70% | Up to 90% at 720+ credit |
| Best fit | Equity already in the rental | Funding a rental purchase or rehab |
Drawing on your home and putting the money into a rental is a common workaround, because lenders approve home lines more readily. The tradeoff is that your residence now secures debt for a business project. If the rental stumbles, your own house is on the line.
A line on the rental keeps the risk tied to the asset that produces the income. The catch is the narrower menu of lenders, and the lower leverage that comes with it.
What the Network’s Investment Line Requires
The terms below reflect select wholesale lenders, they apply only to this product, and every file is reviewed individually. Nothing here is a commitment to lend.
- Leverage: 70% CLTV maximum on an investment property. Credit scores of 720 and 700 both reach that same 70%, so a higher score buys eligibility rather than extra leverage.
- Credit: 700 is a hard floor on investment lines, with no tier beneath it.
- Line size: up to $500,000 total. There is no larger tier for investment property.
- Debt-to-income (DTI): a 50% ceiling. Underwriters review your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
- Valuation: an investment line stays at or below $500,000, so it ordinarily runs on an automated valuation instead of a traditional appraisal. A higher CLTV may require a second valuation, and you can always request a full appraisal.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property are not eligible.
- Limits on you: a borrower can hold at most three lines. A borrower with more than 15 financed properties is not eligible.
- Drawing at closing: at least 75% of the line is drawn at closing.
Market surveys report different numbers. NerdWallet puts typical credit scores for an investment HELOC around 720, with maximum loan-to-value up to 80% and many lenders below 70%. On our network the investment ceiling is 70% CLTV, and it requires 700 credit.
That draw-at-closing rule matters more than it looks. Many investors imagine a HELOC as a dormant reserve that costs nothing until used. On this program, most of the line is drawn on day one, so you are paying on most of it immediately.
Availability is narrower than for DSCR loans. Lendmire arranges these lines in 16 full-service states, while its DSCR investor footprint covers 40 states plus Washington, D.C.
Key Terms Defined
HELOC: a revolving line of credit secured by property, with a draw period followed by repayment.
CLTV (combined loan-to-value): all loans on the property added together, divided by its value.
Draw period: the stretch of years when you can borrow from the line and often pay interest only.
Lien position: your place in line to be repaid. A first lien is paid before a second lien.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly property payment.
PITIA: principal, interest, taxes, insurance, and association dues. It is the payment a DSCR ratio uses.
Seasoning: how long you must own a property before a lender will refinance it on its current value. About 6 months is the common expectation for DSCR cash-out files.
The Title Test: Why an LLC Usually Ends the Conversation
Most investors who hold rentals in an LLC for liability protection hit this wall first. An investment HELOC on our network requires title in the individual borrower’s name, or in an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
That makes this the sharpest structural gap between a HELOC and a DSCR loan. A property already deeded to an LLC has three paths:
1. Move the title. Retitle the property to yourself. You give up the liability separation the LLC provided, so consider that carefully.
2. Borrow elsewhere and contribute the funds. Draw on a property you hold personally and document the money’s path into the LLC.
3. Use a DSCR cash-out refinance. These can keep the entity on title, subject to lender program eligibility.
Retitling is a real cost for some investors, and a quiet one. Check with your attorney before you move a deed.
Underwriting on You, Not the Rent
A HELOC asks whether you can afford the debt. A DSCR loan asks whether the property can. This is the difference that decides who gets approved.
Lenders reviewing a HELOC look at your credit, income, DTI, equity, and reserves. Income documents usually include pay stubs or W-2s, or two years of returns if you are self-employed, along with mortgage statements, leases, and bank statements. Rental income often counts only in part toward your qualifying income.
Every financed property adds to your personal debt picture. An investor with several mortgages can reach the DTI ceiling long before the equity runs out. That ratio, not the value of the rentals, becomes the binding constraint.
DSCR files work differently. They are reviewed property by property. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Our complete DSCR loans guide walks through how that math works.
When a HELOC Fits
A HELOC tends to work when most of these are true:
- The rental sits in your own name or a revocable trust.
- Your credit sits at 700 or better, and your total debt leaves room under a 50% DTI.
- You have a good first mortgage you want to keep.
- The need is a staged, modest sum, such as a rehab that raises rent.
- The property is paid off, so there is no first mortgage to protect.
- You can carry a floating payment on a mostly drawn line through a slow lease-up.
The paid-off case is a clean one. With no first loan in place, there is no cheap first mortgage to lose by borrowing a second.
When It Does Not Fit
A HELOC tends to fail in these situations:
- The rental is in an LLC and you want to keep it there.
- Your DTI is crowded by other mortgages or personal debt.
- You need a large lump sum. The $500,000 cap and 70% CLTV ceiling constrain you.
- The property barely covers its current payments. A floating payment can push it under water.
- You plan to borrow against thin equity. At 70% CLTV there is little room once a first mortgage is in place.
- You want a fixed cost. The pricing floats on this product and does not convert.
A cash-flow-negative landlord should not borrow a floating second lien to cover the gap. The line becomes a bridge to nowhere.
Stress-Testing the Line Before You Sign
A common mistake with these lines is treating floating debt as permanent capital. Run three tests before drawing.
Test one: the stacked payment. Say a rental covers its fixed first mortgage with a healthy cushion, around 1.3x coverage. Add an interest-only payment on a line that is at least 75% drawn at closing. The combined burden can pull coverage toward 1.0x or below, even though the first mortgage never changed.
Test two: vacancy. Take a month or two of vacancy out of the year. Look at what is left to pay both loans. A slow lease-up after a rehab extends the carry, and the floating payment keeps running while you wait.
Test three: the step-up. After the 5-year draw on our network’s investment line, principal begins amortizing over 25 years. The CFPB booklet on home equity lines warns that payments tied to a floating index can change even if you borrow nothing more. It also notes that some plans can require paying the full balance at once. Check your agreement for either feature.
The CFPB’s 2014 booklet gives the sizing method used earlier. In its worked example, a $100,000 home at a 75% limit with a $40,000 mortgage yields a $35,000 line. That figure is illustrative and predates today’s investment programs. Use the method, not the numbers.
The same booklet adds one more risk. Lenders can freeze or reduce a line if the property’s value falls significantly or your finances change materially. A rental line you planned to draw on in year four may not be there.
When a DSCR Cash-Out Refinance Is the Better Tool
Pure rental purchases and larger equity pulls usually move to DSCR. A DSCR cash-out refinance replaces your first mortgage with a new loan sized to the property’s value. It is reviewed on the rent covering the payment instead of your personal DTI.
Here are the typical ranges we see across the wholesale network. Each depends on the borrower, property, and lender guidelines.
- Cash-out leverage: on a standard long-term rental, most programs top out around 75% LTV.
- Seasoning: about 6 months of ownership is the common expectation.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
- Reserves: commonly around 6 months of PITIA, though they vary by lender, leverage, size, and transaction type.
- Term structures: the spine is the 30-year fixed. Extended terms and interest-only periods are available through select lenders in the network.
Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it, so a property can clear the ratio and still lose money.
The cost of the cash-out is that it replaces your existing first mortgage. If that loan has favorable terms, you give them up. That is the honest tradeoff, and it is why the paid-off property and the keep-my-first-mortgage investor tilt toward the HELOC.
| Tool | Underwritten on | Payment type | Weak point |
|---|---|---|---|
| Investment HELOC | You (credit, DTI) | Floating, interest-only draw | 70% CLTV cap, no LLC |
| DSCR cash-out refinance | Property rent | Fixed, or extended terms available | Replaces your first mortgage |
| Primary-home HELOC | You (credit, DTI) | Floating | Your residence secures it |
| Savings or partner capital | Not applicable | None | Slower to build |

Picking a Route by Investor Profile
The small-rehab owner. You hold one rental personally with a fixed first mortgage you like. You need a modest sum for a kitchen and bath. A HELOC fits, as long as the rent survives the stacked payment.
The large one-time need. You want to pull out a big sum to buy the next property. A HELOC’s $500,000 ceiling and 70% CLTV may not stretch far. A DSCR cash-out refinance at up to 75% LTV on a standard rental usually yields more.
The LLC portfolio. Your doors sit in entities. A HELOC is generally off the table. Look at DSCR cash-out, subject to lender program eligibility.
The high-income, cash-flow-thin investor. Your salary looks strong, but the rentals barely cover themselves. A HELOC might approve you, yet it adds a floating payment to a thin property. Be wary.
The multi-property scaler. You own many financed rentals. Personal DTI will bind you on a HELOC, and more than 15 financed properties makes you ineligible. DSCR files are reviewed property by property, so they scale differently.
A Word on Taxes
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.
Frequently Asked Questions
Can I use a HELOC to buy a rental property?
Yes, in two ways. You can draw on a line secured by your primary home and put the money toward the purchase, or you can borrow against an existing rental you hold in your own name. The first route is easier to qualify for but puts your residence at risk. Either way, you are underwritten on your own credit and debt load, not on the new property’s rent.
Does an LLC change the answer?
Yes. On our network, an investment HELOC cannot be held in an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. Title must be in your individual name or a revocable living trust. A property already in an LLC needs a title change or a DSCR cash-out instead.
HELOC or cash-out refinance: which is cheaper to keep?
Neither is universally cheaper, because pricing varies by lender and file. The structural difference is what happens to your first mortgage. A HELOC leaves it in place, so it favors an investor with a first loan worth keeping. A cash-out replaces it, so it favors an investor who needs more cash or who qualifies better on rent than on personal income.
What if the rental sits vacant?
The floating payment keeps running either way. Because at least 75% of the line is drawn at closing, you are paying on most of it from the start. A HELOC does not look at the rental’s rent, so a vacancy will not change your approval, but it can strain your cash flow. Keep reserves for the gap.
How much can I borrow?
On our network’s investment line, the ceiling is 70% CLTV, and no more than $500,000 total. The amount depends on your property’s value minus what you owe on the first mortgage. A line above $500,000 is available only on a primary residence.
