HELOC vs Home Equity Loan Behind a Sub-4% First Mortgage Worth Keeping

The Quick Read: Pick a HELOC when your cash need is staged and the property sits in your own name; pick a home equity loan when you need one known amount; and when a cash-out refinance would replace a first mortgage worth keeping, a second lien leaves that first loan in place. Both products sit behind your first loan as a separate lien. Neither one rewrites that first loan’s terms.

• A home equity loan is a lump sum with a fixed repayment schedule. A HELOC is a credit line with a draw phase and a repayment phase.
• On an investment property, the network’s equity line tops out at 70% CLTV (combined loan-to-value, every lien added together) and $500,000, with a 700 minimum credit score, subject to lender guidelines.
• Both are underwritten mainly on you, your credit and your debts. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
• An LLC cannot hold title on the network’s equity line, which is the sharpest structural gap between a line and a DSCR loan.

Here is the honest answer on who each option is for. A HELOC fits an investor who will spend equity in pieces, such as a rehab in phases or a pipeline of down payments, and who can absorb a payment that moves. A home equity loan fits an investor with one defined expense and a preference for a fixed schedule from day one. Neither is “better.” The right pick depends on how you will spend the money and how the property is titled.

Side-by-Side

The HELOC column describes the network’s equity line that Lendmire, a mortgage broker, places through select wholesale partners. The home equity loan column shows published industry norms, which vary by lender. Pricing is left out on purpose, because it lives in the calculator and changes by file.

Two rows deserve a second look. The first is access to funds. The network line requires at least 75% of the line to be drawn at closing, so it behaves partly like a lump sum. A HELOC bought as a standby reserve is a different animal, and a network line is not built that way. The second is vesting. A rental held in an LLC cannot secure the network’s line, subject to program requirements.

When a HELOC Is the Better Fit

A HELOC wins when the amount and timing of your spending are uncertain, because you draw only what you need after the opening draw. A line also lets you pay down and borrow again during the draw phase, which a closed-end loan cannot do. Think of an investor who plans a multi-stage renovation and does not know the final bill.

The network line has a defined shape on investment property. It runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and it floats through both phases without converting to a fixed structure. Later draws can carry a minimum, and some network lines set it at $1,000. Federal consumer guidance, such as the CFPB’s HELOC explainer, notes that draw periods vary by plan and that payments are often significantly higher once repayment starts. Some plans can even demand the whole balance when repayment begins. Read your line’s terms for that clause.

Three situations favor the line:

• Phased projects. Draw for phase one, pause, then draw again if the numbers still work.
• Equity on your own residence. On a primary residence, the network’s line reaches 90% CLTV only with a 720-or-better credit profile, up to $500,000. Lower credit tiers step down from there.
• A bridge you will pay down soon. If you expect cash to come back in, an interest-only draw phase gives you room.

The cost of a HELOC is exposure. Because the line floats, your monthly obligation can move even when you draw nothing more. If you cannot absorb that, a line is the wrong tool.

When a Home Equity Loan Is the Better Fit

A home equity loan wins when you know the exact number. A down payment on the next rental, a roof, a defined payoff: all of these call for one lump sum and a schedule that never changes shape. The repayment is level from the first month, so you will not face a step-up when a draw phase ends.

The tradeoff is that the payment starts immediately, before the project produces any rent. That matters most on a value-add rental, where the loan payment begins long before the unit earns income. Run your own reserves honestly before choosing this route.

A caution applies to both products. A larger equity cushion can lower your monthly burden, but it does not erase leverage caps, credit floors, or property eligibility. Not offered on the network’s equity programs: manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, and agricultural zoning.

Does Either One Touch the First Mortgage?

A second lien is a separate loan with its own payment, so it does not change the first mortgage’s balance, term, or cost. That is the whole point of keeping a low-cost first loan. A cash-out refinance, by contrast, replaces the entire first mortgage with a new one.

The due-on-sale clause is the main thing to check before adding a second lien. It lets a lender call a loan if the property is sold or transferred without consent. Federal law generally bars a lender from calling a loan on residential property of fewer than five units because a subordinate lien was created. Two caveats matter for investors. The protection is framed around residential property and a transfer of occupancy rights, so read the first mortgage’s note and rider before assuming it covers your rental. And a property with five or more units falls outside that statutory protection, so the note controls.

Moving title into an LLC is a different matter. The statute’s exceptions cover subordinate liens and certain transfers into a borrower’s own living trust, not a deed into an LLC. Re-titling a rental out of an LLC to qualify for an equity line also gives up the liability separation the LLC provided. If your property is already in an LLC, a vesting change or a DSCR cash-out becomes the realistic comparison.

Is Your First Mortgage Worth Keeping?

A first mortgage is worth keeping when the cost of the second lien, blended with the first, stays below what one replacement loan would cost. You can test this without any pricing here. Use the calculator for the inputs and follow these steps:

1. Write down the first mortgage’s remaining balance and its cost.

2. Write down the amount you need and the second lien’s cost.

3. Weight each loan’s cost by its balance to get a blended cost for the keep-the-first option.

4. Price a cash-out refinance for the full combined balance, then compare it to the blend.

5. Add closing costs for each path and check the full monthly obligation, not just the cost.

The smaller the cash need relative to the first balance, the more weight the low-cost first carries, and the more a second lien tends to win. A large cash need pulls the blend toward the second lien’s cost and narrows the gap. That is why a draw of modest size behind a small, old first mortgage is the classic keep-it case, and a large draw is where a refinance deserves a fair hearing.

Combined leverage matters too. The first mortgage’s balance consumes part of the equity, so CLTV counts every lien together. Equity is not the same as borrowing room.

Stress-Test the Second Lien

Test the line at full draw, not at today’s balance. The network qualifies a line on the interest-only payment calculated on the maximum draw, with a 50% maximum DTI (debt-to-income, your monthly debts divided by gross monthly income). If your file only works at a partial draw, the underwriting will not see it that way.

Then picture the draw phase ending. The repayment phase amortizes the balance over 25 years on the network’s investment line, so the monthly obligation steps up when interest-only ends. A home equity loan has no such cliff. If a step-up would strain your portfolio, choose the closed-end loan or draw less.

Finally, plan the exit. A line that never converts to a fixed structure must be paid down, refinanced, or paid off at a sale. When you sell, both liens are generally paid from proceeds at closing.

When the Second Lien Is the Wrong Tool

Sometimes neither product fits. A DSCR cash-out refinance on the rental itself replaces the first mortgage, but it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. 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.

Here is how the network’s DSCR cash-out looks for a standard rental:

• Leverage: Up to about 75% LTV on a standard-rental cash-out refinance, with about 6 months of seasoning as the common expectation. Short-term-rental collateral caps at 70% on a cash-out.
• 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: Minimum scores vary by program and lender. A 620 floor exists only in parts of the network, and higher scores unlock the strongest leverage tiers.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders), with 30-year fixed as the spine and extended terms available through select lenders.
• Vesting: An LLC can hold title, subject to program eligibility, which a standard equity line cannot do.

Clearing 1.00 does not mean the property cash flows. Repairs, vacancy, management, utilities, and capex sit outside the DSCR calculation, which compares rent to PITIA only (principal, interest, taxes, insurance, and association dues).

The tradeoff is simple. A DSCR cash-out gives entity vesting and property-based qualification but replaces your low-cost first mortgage. The second lien keeps the first intact but ties you to your personal credit and debts. For a deeper look, Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance Behind a Sub-4% First Mortgage Worth Keeping covers that fork in detail. The complete DSCR loans guide explains how rental coverage works from scratch.

What the Network Line Asks of You

Eligibility for the network’s equity line goes beyond equity. On an investment property the minimum credit score is 700, and the line is capped at $500,000. Lines at or below $500,000 ordinarily run an automated valuation, although a higher CLTV may need a secondary valuation, and you can always request a full appraisal. The credit report must be no more than 90 days old at closing.

A few limits apply to the whole portfolio. A borrower can hold up to three lines at once. A borrower who owns more than 15 financed properties is not eligible. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure, deed-in-lieu, short sale, and pre-foreclosure history are handled in tiers, and investment files follow a 7-year path for foreclosure and a 4-year path for the others.

Availability is narrower than the DSCR footprint. The equity line is offered in 16 full-service states, while Lendmire’s DSCR investor loan programs reach 41 markets, including Washington, D.C. Every figure above is subject to lender guidelines and full file review, and none is a commitment to lend.

Key Terms Defined

• CLTV: Combined loan-to-value, which adds every lien on the property together and divides by the property’s value.
• Draw period: The stretch when you can borrow from a HELOC, usually with interest-only payments.
• Repayment period: The stretch after the draw ends, when you repay principal and interest.
• Subordinate lien: A loan that sits behind the first mortgage in claim on the property.
• DSCR: Debt service coverage ratio, which divides monthly rent by the monthly debt payment on the property.

The Verdict

Choose the HELOC when your spending is staged, the property is in your name, and you can absorb a payment that moves and later steps up. Choose the home equity loan when the number is known and you want a level schedule. Choose neither when the property is in an LLC and you would rather keep entity protection, or when the cash need is so large that a full refinance, run through the blended-cost steps above, comes out ahead.
