Cash-Out Refinance vs Home Equity Loan for a Low First Mortgage

The Quick Read: A cash-out refinance replaces your low first mortgage with one new loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, while a home equity loan keeps the low first mortgage in place and adds a second lien that qualifies mostly on you, meaning your credit, debt-to-income, and equity. Which one fits depends on who holds title, how much cash you need, and how much the existing first mortgage is worth keeping.

• A cash-out refinance reprices and resets the whole balance, so you give up the old loan’s terms.
• A home equity loan leaves the first mortgage alone but adds a second payment and a combined-leverage ceiling.
• On a rental, a second lien tends to require individual or revocable-trust title, which rules out most LLC-held properties.
• Larger cash needs usually point to the cash-out refinance, because investment-property equity lines on our network cap at $500,000 in total.
• Rent coverage helps a cash-out file, but it doesn’t make either option “free” cash flow.

The Honest Answer First

The home equity route is for the owner whose first mortgage is the best asset on the property. You hold title personally, you need a moderate amount of cash, and your credit and debt-to-income are strong. You keep the old loan and accept a second one behind it.

The cash-out refinance is for the owner who needs more cash, holds the property in an LLC, or is already stretched on personal income ratios. It also suits the owner whose first mortgage isn’t worth protecting. You replace the first loan and the new loan is judged mostly on the rent the property produces.

Neither is better in the abstract. A low first mortgage raises the price of the cash-out option, and personal qualification raises the price of the equity option. The rest of this article shows where each cost lands.

Side-by-Side

The second column shows published industry norms for a home equity loan or line on a rental, plus the terms of the equity lines our wholesale network places. Programs change, and every file is underwritten individually.

PITIA is principal, interest, taxes, insurance, and association dues. DSCR, the debt service coverage ratio, is monthly rent divided by that total.

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.

Why a Low First Mortgage Changes the Math

A cash-out refinance doesn’t just borrow new money. It replaces the entire first loan, so the new terms apply to the full balance. The cash you take is only part of what gets repriced.

If your existing first mortgage is far better than anything available today, you give that up. You also restart the amortization clock. Years of principal paydown are folded into a fresh schedule.

A second lien works the other way. The CFPB explains that a second mortgage is secured by the same house as the first, and the second lender is paid second if the home is sold. That is why a second lien typically carries more cost per borrowed dollar. It also means the new money is the only piece priced at second-lien terms.

So the real question is not which product is cheaper in the abstract. It is whether the value of the old first loan outweighs the cost and friction of carrying two loans. The bigger the first balance relative to the cash you need, the more a second lien tends to make sense. The smaller the first balance relative to the cash you need, the less there is to protect.

When the Cash-Out Refinance Is the Better Fit

A cash-out refinance wins when title, size, or personal ratios block the second lien. It also wins when the old first loan isn’t worth protecting.

Your rental sits in an LLC. On our network, an equity line on a rental requires title in an individual’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts can’t hold title. A DSCR cash-out refinance can work with entity-titled properties, subject to program eligibility. Re-vesting into your own name to qualify for a line can raise due-on-sale questions with the existing first lender, so check with the servicer before you move title.

You need more than a line can give. Investment-property lines on our network cap at $500,000 total. A standard DSCR cash-out refinance reaches up to $3,000,000 on standard programs, with smaller balances available through select lenders. For a larger need, the line simply runs out.

Your personal ratios are the constraint. An equity line on a rental is tested on personal debt-to-income, up to 50% on our network, calculated on the interest-only payment at the maximum draw. Owners with many financed properties can hit that wall. A DSCR cash-out qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It doesn’t run the same personal ratio test.

You want one payment and one lender. Two liens mean two servicers and two sets of conditions. A single new first lien simplifies that.

Here is what to expect on a standard rental cash-out:

• Leverage: tops out around 75% LTV on a cash-out refinance of a standard rental. A short-term rental cash-out tops out around 70%.
• Seasoning: about 6 months of ownership is the common expectation.
• Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ opens the strongest leverage tiers.
• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Reserves: commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Loans above $1,500,000 typically step up to about 9 months.

Clearing 1.00 does not mean positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.

When the Home Equity Loan Is the Better Fit

A second lien wins when the first mortgage is the prize and your personal profile is strong. The goal is to borrow without touching the loan you most want to keep.

You hold title personally and need a moderate amount. Our network’s investment-property lines run from $25,000 to $500,000. They require a 700 minimum credit score and cap at 70% combined loan-to-value (CLTV) on an investment property. CLTV counts every lien against the property’s value, so your existing first mortgage uses up part of that room before the new line gets any.

Market surveys report tougher terms than that. NerdWallet reports that investment-property lines often want 720+ credit, 80% maximum LTV with many lenders going lower, and six months or more of reserves. On our network, an investment property line stays at 70% CLTV with a 700 minimum credit score. Those are different yardsticks, so compare like with like.

Your valuation needs are light. Lines at or below $500,000 ordinarily run an automated valuation, though a higher CLTV may require a secondary valuation. NerdWallet notes that some lenders ask for multiple appraisals on investment properties, so expect variation.

Your property is a small residential rental. Eligible types include single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible. Five or more units are commercial.

The draw structure fits your plan. An investment line on our network runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. That matters because you start paying on most of the line immediately, so a line is not a cheap standby cushion.

Availability is narrower than the DSCR footprint. Equity lines are placed in a smaller set of states, so confirm availability for your property. Borrowers are limited to three lines, and an owner of more than 15 financed properties is not eligible.

The Second-Lien Gates Most Owners Miss

A second lien depends on permission and sequencing. It is not just a qualification test.

The first lender’s documents must tolerate a second lien. Get the servicer’s position in writing before you spend money on an application.

A later refinance gives the junior lender a veto. When you refinance the first loan, the second lender can subordinate (agree to stay behind the new first) or be paid off. It has no duty to subordinate. Lendmire’s piece Cash-Out Refinance vs Resubordination for a Low First Mortgage covers that scenario.

A second payment lowers combined coverage if your first loan is DSCR. The same rent must cover both payments. A first loan that clears 1.00 alone can fall below it once the second payment lands. If your first mortgage is a DSCR loan, your equity line has to survive that math. This is a common trap when stacking debt on a financed rental.

Sequencing matters. Investors generally put the DSCR first loan in place and the equity line behind it, rather than the reverse. A DSCR loan sitting behind an existing second lien is rare.

Exit fees reset on a payoff, not on a second lien. If your first loan carries a prepayment or exit fee, a cash-out refinance triggers a payoff and starts a new clock. A second lien leaves the first note’s clock running.

Cash Need, Leverage, and the Two-Test Rule

A larger down payment or more equity can lower the monthly payment and lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Picture an owner with a rental whose first mortgage sits well below today’s market. The property has solid equity, rent covers the existing payment comfortably, and the owner needs a mid-sized sum for the next purchase. An equity line behind the first loan preserves the old terms. A cash-out refinance would convert that equity to cash at the price of resetting everything.

Now change the picture. The same owner holds the property in an LLC and needs a sum above the line ceiling. Re-vesting into personal title raises a due-on-sale question, and the line can’t reach the needed amount anyway. The cash-out refinance becomes the practical path.

The CFPB’s equity guide notes that a home equity loan is a separate mortgage with its own monthly payment, and that equity loans are usually repaid over a shorter period than 30-year mortgages and cash-out refinances. That shorter schedule means a heavier payment per borrowed dollar. Compare payment burden with your rent coverage before you commit.

Across our wholesale network, we see the same pattern on stacked files. The owners who get surprised didn’t miss the second lien’s qualification test. They missed what it did to coverage on the first loan, or they skipped the servicer’s written position on a second lien.

Common Mistakes

• Treating the equity line as free money. The second loan adds to your debt burden and puts the property at risk if you can’t repay.
• Comparing market figures to network figures. Surveys describe the broader market, while programs have their own ceilings.
• Forgetting that LLC title blocks the line. Check vesting before you shop.
• Ignoring subordination on the next refinance. The junior lender can say no.
• Counting the exit fee as part of DSCR. It isn’t part of the ratio, but a second lien’s payment is.

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.

The Verdict

Choose the equity route when you hold personal title, need a moderate sum, qualify on your own ratios, and the first mortgage is a clear asset you want to protect. Choose the cash-out refinance when you need a larger sum, hold the property in an LLC, or your personal debt-to-income is the limiting factor. Also choose it when the old first loan has little left worth protecting.

Run both against your own file. Check title, the size of the cash need, the existing loan’s remaining value, and your servicer’s position on a second lien. If the answers conflict, the cash need usually decides.
