HELOC vs Cash Out Refinance for a Landlord Keeping the First Mortgage

The Quick Read: A home equity line of credit (HELOC) adds a second loan behind your first mortgage and qualifies you personally, while a cash-out refinance replaces the first mortgage with a new loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines and file review. Which one fits depends on who holds title, how much you need, and how much your current first mortgage is worth keeping.

• HELOC: keeps your first mortgage untouched, but on an investment property it tops out at 70% combined loan-to-value (CLTV) and a $500,000 line.
• Cash-out refinance: reaches up to roughly 75% loan-to-value (LTV) on a standard rental, but it reprices the entire balance, not just the new money.
• Title decides a lot: an LLC cannot hold title on the HELOC, while a DSCR cash-out generally can, depending on program guidelines.
• Coverage is not cash flow: clearing the rent-to-payment test says nothing about repairs, vacancy, or management.

The honest answer is simple. The HELOC is for the landlord who owns the rental personally, likes the first mortgage, and needs modest equity. The cash-out is for the landlord with entity title, a larger need, or a first mortgage not worth protecting. Plenty of landlords sit in the middle, and the rest of this piece sorts them out.

Side-by-Side

Here is how the two structures compare on the points that actually change outcomes. The HELOC column reflects the investment-property terms across the wholesale network Lendmire (a mortgage broker, not a lender) works with. The cash-out column reflects the DSCR programs in that same network. All figures are typical ranges, subject to lender guidelines.

PITIA means principal, interest, taxes, insurance, and association dues. It is the monthly obligation a lender weighs against rent.

When the HELOC Is the Better Fit

The HELOC wins when the first mortgage is the best asset on your balance sheet and you need a measured amount of equity. Leaving that loan alone means leaving its terms alone. A cash-out replaces everything, so the whole balance moves to the new loan’s terms.

This path suits you if these points describe your file:

• You hold title personally or in a revocable living trust.
• Your credit sits at 700 or above. That is a hard floor on an investment line, and a 720 score earns the same 70% CLTV ceiling, so extra score buys eligibility rather than extra leverage.
• Your personal debt-to-income ratio (DTI) can carry a new obligation. The network’s maximum is 50%, and the line is qualified on the interest-only payment at the maximum draw. NerdWallet reports that HELOCs on investment property in the broader market typically look for DTI between 40% and 50%.
• You need $500,000 or less. A line above that is reserved for primary residences.
• The property is a single-family home, a 2-4 unit building, a PUD, a townhome, or a condo (non-warrantable condos included).

The structure is worth understanding. On an investment property, the line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. The line stays variable and never converts to a fixed structure. That is a different animal from a revolving card-style line. You draw most of it on day one, so plan around a mostly-funded loan.

The line also sits in first or second position, which matters if you keep a first mortgage. Your existing note still needs to coexist with a second lien, so read it.

Borrowers with a low first balance get the most from this. Lendmire’s piece HELOC vs Cash-Out Refinance for Homeowners Keeping a Low First Mortgage covers the owner-occupied version of this same decision.

When the Cash-Out Refinance Is the Better Fit

The cash-out wins when title is in an LLC, the need is large, or the property’s rent carries the loan better than your personal income carries a second payment. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your credit and reserves still get reviewed.

That makes it the stronger tool in several situations:

• Entity title. LLCs, corporations, partnerships, and land or irrevocable trusts cannot hold title on the HELOC. A property already deeded to an LLC either needs a vesting change or a DSCR cash-out, depending on program terms. Moving title to your own name to chase a HELOC gives up liability separation and may raise due-on-sale questions on your current mortgage, so talk to an attorney first.
• Bigger needs. The line caps at $500,000 on an investment property. DSCR loans run up to $3,000,000 on standard programs (smaller balances available through select lenders).
• Higher leverage. A cash-out on a standard rental goes up to about 75% LTV. On short-term-rental collateral, the cash-out ceiling is 70%.
• Heavy portfolios. A HELOC borrower can hold only three lines, and anyone owning more than 15 financed properties is ineligible. A DSCR loan leans on the property rather than your personal income, so it scales differently across many holdings.
• Messy traditional personal-income documentation. Heavy write-offs can understate a landlord’s real cash flow. Rent-based underwriting reads the property instead.
• A first mortgage not worth saving. If your current note is a weak one, replacing it costs you nothing. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

A typical DSCR file asks for a lease or appraisal rent estimate, credit, reserves, and entity papers. Traditional personal-income documentation, W-2s, and pay stubs are generally not part of it. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open stronger leverage and pricing tiers.

Reserves vary by lender, leverage, loan size, and transaction type. About six months of PITIA is common. Larger loans often step up to roughly nine months.

How Much Room Does Keeping the First Mortgage Actually Leave?

This is where landlords get surprised. A HELOC limit is a percentage of value minus what you owe, and the CFPB’s HELOC booklet describes that exact subtraction. The lender also weighs your income, debts, and credit history.

Run it as percentages of value. Say a rental carries a first mortgage equal to 45% of value. An investment HELOC at 70% CLTV leaves room for up to 25 points of value, subject to the $500,000 cap and your DTI. A cash-out at 75% LTV on a standard rental could extend to 30 points of cash over the old payoff. That is more room, but it comes with a new loan on the full balance.

Now flip it. Say the first mortgage sits at 65% of value. The HELOC leaves about 5 points of room. The cash-out still allows 10 points beyond the payoff, if the rent supports the larger loan. Because every dollar is refinanced, a bigger cash-out means a bigger obligation and thinner coverage. Rent, not equity, can become the limit.

Neither number is a promise. Each file runs on credit, valuation, and lender review. Lendmire’s illustrative calculator can model these combinations, but treat it as an estimate.

What Breaks Each Option

The HELOC breaks on eligibility. Title in an LLC kills it. A credit score under 700 kills it. Properties that are manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agricultural-zoned are not eligible. Many investors find rental lines hard to locate because the lender pool is smaller and limits are lower, as NerdWallet notes.

Investment lines are also available only in the 16 states where Lendmire has full-service lending. That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C. Valuation on a line of $500,000 or less usually runs through an automated model, with no traditional appraisal. That model may not capture the value a recent rehab added.

The cash-out breaks on coverage. If rent does not support the new, larger loan, proceeds shrink or the deal works to a select-lender path with leverage and terms adjusted. A recently bought property may also need about six months of seasoning before the new value counts. Short-term-rental collateral needs a 640+ score and roughly 12 months of hosting history. DSCR loans are not offered on manufactured homes (single- or double-wide), log homes, or barndominiums.

Both can hurt you. Both are secured by property. As the CFPB explains, a HELOC is open-end revolving credit and you could lose the property if you fall behind. A cash-out carries the same logic with a bigger balance.

One trap deserves its own paragraph. Clearing a 1.00 coverage ratio is not positive cash flow. The DSCR counts rent against PITIA only. Repairs, vacancy, management, utilities, and capital expenses all sit outside it. A property can clear coverage and still bleed cash.

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.

Which Landlord Are You?

Think of three common profiles.

The personal-title owner with a great first mortgage. Two rentals, individual title, strong score, needs a smaller sum for a renovation. The HELOC is the natural pick, as long as the CLTV math leaves room.

The LLC owner with a large need. Four doors in an entity, wants a down payment for the next one. The HELOC is off the table on title alone. A DSCR cash-out is the realistic route, assuming rent covers the larger loan.

The in-between owner. Title is personal, the first mortgage is decent but not special, and the need is big. This one is a toss-up. The HELOC protects the first note but caps at 70% CLTV. The cash-out unlocks more leverage but swaps the note. Price both on the property, then compare total cost across the full balance, not just on the new money.

A third path is borrowing against your own residence instead of the rental. It is outside this comparison, but for some landlords it is the simplest answer.

The Verdict

Choose the HELOC if you hold title personally, score 700 or above, need $500,000 or less, and your first mortgage is worth guarding. Choose the cash-out if you hold title in an entity, need more than a modest line, or want leverage up to about 75% on a standard rental and the rent supports it. Each option beats the other in the right file.

Neither is cheap in every case, and neither is safer in every case. Keep the first mortgage when its terms are the asset. Replace it when the property, the title, or the size of the need says the old structure no longer fits.
