Cash-Out Refinance vs HELOC for a Homeowner Buying a Second Home

The Quick Read: A cash-out refinance replaces your current mortgage with a bigger one and hands you the difference in one lump sum, while a home equity line of credit (HELOC) leaves your first mortgage alone and adds a separate line you borrow against. Which one fits depends on what you are protecting and how certain your cash need is.

• A cash-out refinance suits one large, known cash need, but it resets your first mortgage.
• A HELOC suits a smaller or uncertain need and keeps the first mortgage in place.
• On the HELOC programs Lendmire places, 90% combined leverage exists only at a 720-or-better credit profile, and only on primary-residence and second-home lines.
• Investment-property lines cap at 70% combined leverage and $500,000 total.
• If the second home will be a rental, the purchase loan is usually a DSCR loan that qualifies primarily on the property’s rental income, subject to lender guidelines.

The Honest Answer First

Pick the cash-out refinance when you need a big, one-time sum and your current first mortgage is not something you are trying to protect. Pick the HELOC when you want to keep that first mortgage untouched, or when the amount you need is still moving.

Neither is better in general. They solve different problems.

Here is a plain-English glossary before the details. Your first mortgage is the loan you took out to buy the home you live in. A lien is a lender’s legal claim on a property until the debt is repaid. CLTV is combined loan-to-value: your first mortgage plus the new line, divided by the home’s value. A HELOC’s draw period is the stretch when you can borrow against the line.

Both options put the home you already own behind the debt. That is the point most buyers underweight. You are not just buying a second property. You are tying the purchase to the roof you sleep under.

Side-by-Side

The table below compares the structure of each option, not the pricing. The cash-out column reflects published industry norms, which vary by lender. The HELOC column reflects the guidelines of the wholesale lenders Lendmire works with. Every figure is subject to lender guidelines and full file review.

Three rows deserve a closer look.

The first is the 75% draw at closing. A HELOC is marketed as flexible, but on these programs most of the line is funded on day one. Do not count on a mostly undrawn safety net.

The second is vesting. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already deeded to an LLC would need a vesting change, or a DSCR cash-out instead.

The third is property eligibility. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned property are not eligible.

When a Cash-Out Refinance Is the Better Fit

A cash-out refinance fits when the cash need is large, single, and known. If you are buying one property with a set down payment, a lump sum matches the job. You get the money once, you pay one mortgage on the home you live in, and nothing stays open for later.

It also fits when your existing first mortgage is already due for a change. If you were going to refinance anyway, folding the cash into that move avoids stacking a second lien on top. NerdWallet frames the choice around the size of the draw and the closing-cost break-even. That is a sound way to test it. A bigger draw spreads the closing costs over more borrowed cash.

Three honest drawbacks come with it:

• It resets your terms. The new loan replaces the old one, which may lengthen your payoff timeline.
• It is a heavier process. Expect a full appraisal, income and credit review, and title work.
• Your debt is larger. Everything you pulled out is now part of one bigger loan on your home.

If the equity sits in a rental you already own rather than your home, the answer changes. A DSCR cash-out refinance on a rental tops out around 75% LTV across most of the network. About 6 months of seasoning, meaning the waiting period since you bought or last refinanced, is the common expectation. Short-term-rental collateral runs tighter, with cash-out capped at 70% on those properties. Entity-titled rentals may be eligible, subject to lender program eligibility. That path keeps the borrowing on the investment and off your personal residence.

When a HELOC Is the Better Fit

A HELOC fits when you want your first mortgage left alone, or when you do not yet know the total you need. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly during a draw period, which could last 10 years, for example. That helps if the second home needs furniture, repairs, or a closing-cost top-up on top of the down payment.

On the programs Lendmire’s network places, lines come in two draw structures on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other has a 5-year interest-only draw followed by a 25-year repayment. Investment lines use the 5-year and 25-year structure only. Pricing on these lines floats through both phases and never converts to a fixed structure.

Lines run from $25,000 to $750,000. A line above $500,000 is primary-residence only. It needs a 700-or-better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal. A line at or below $500,000 ordinarily runs automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation.

Credit and leverage move together. On a second-home line, the ceiling steps like this, each up to $500,000:

• 720+: up to 90% CLTV
• 680 to 719: up to 85% CLTV
• 660+: up to 80% CLTV
• 640+: up to 75% CLTV

The minimum on a second-home line is 640. Debt-to-income can run to 50%. It drops to 45% for credit profiles from 600 to 679, and anything above 45% needs a 680 minimum. The line is qualified on the interest-only payment calculated on the maximum draw, so the stress test is tougher than the amount you actually borrow on day one.

The risks are real. The CFPB’s HELOC booklet says lenders may freeze or reduce a line when the home’s value falls or the borrower’s finances worsen. It also says you generally must pay the line off in full if you sell the home. A line you counted on as a backstop can shrink exactly when the market turns.

Availability is narrower than the DSCR footprint. HELOC placements run only in Lendmire’s 16 full-service states, while its DSCR investor programs cover 41 markets, including Washington, D.C. A borrower may hold up to three lines, and anyone with more than 15 financed properties is not eligible.

Where Both Options Run Into Trouble

Whichever route you pick, the second-home lender still underwrites you from scratch. Three things trip people up.

Your debt load stacks. With a HELOC you carry the first mortgage, the line, and the new loan at once. With a cash-out you carry a bigger first mortgage and the new loan. Either way your personal debt-to-income ratio absorbs the extra obligations. A sizable stack can push a borrower past the 45% and 50% thresholds above before the purchase lender even looks at the deal.

Borrowed down payments get scrutiny. Many investors fund a down payment this way, but acceptance of equity-sourced cash is lender-specific. Ask the purchase lender before you open the line, not after.

You are close to fully leveraged. If the line covers most of the down payment, you have little cash cushion. That is fine when the property clearly carries itself. It is painful when it does not.

One more point on tax. 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.

What If the Second Home Will Be a Rental?

If you plan to rent it out, the purchase loan is often a DSCR loan. DSCR stands for debt service coverage ratio. It compares the property’s rent to its monthly PITIA: principal, interest, taxes, insurance, and association dues. Lenders divide the rent by that total to get the coverage number. It is not a personal-income test, so qualification runs on the property’s rental income, subject to lender guidelines. The details live in Lendmire’s complete DSCR loans guide.

Here are the typical network ranges for a DSCR purchase:

• Most files land at 75% to 80% LTV on a purchase, meaning 20% to 25% down.
• Select programs reach 85% LTV with roughly a 700-plus score.
• A 620 credit floor exists in parts of the network. Most programs want around 660, and 700 and above unlocks the strongest leverage.
• Loans reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
• Reserves commonly run around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type.

On coverage, 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 better terms.

Here is the catch: clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.

Now picture an investor buying a rental at 75% LTV with rent that covers the payment at around 1.15x. The property is reviewed on its own numbers. But if the 25% down came from a line against the investor’s home, the file has two tests to pass. The deal must clear the coverage test, and the investor’s personal finances must carry the line. The strongest files clear both. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

A larger down payment can lower the payment and lift the ratio. It does not erase leverage caps, credit floors, reserve rules, or property eligibility.

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. Lendmire’s piece Cash-Out Refinance vs HELOC for a Second-Home Down Payment goes deeper on that exact funding question. For a different borrower profile, see Lendmire’s article HELOC vs Cash-Out Refinance for a Retiree on a Second Home.

A pattern shows up often in files like these. Borrowers who open the line first and shop the purchase loan second sometimes learn the purchase lender wanted the funding plan documented earlier. The cleaner sequence is to confirm the purchase lender’s view on equity-sourced funds, then size the line.

So Which One Should You Choose?

This is close to a toss-up on paper. In practice the decision usually turns on three questions.

Do you know the exact amount? If yes, a cash-out refinance matches a single need. If no, a line gives you room, though remember most of it is drawn at closing on these programs.

Do you want your first mortgage untouched? If yes, lean HELOC. If you were refinancing anyway, lean cash-out.

Where does the risk sit? Both secure the debt on the home you live in. Cash-out piles it into one larger loan. A HELOC adds a variable-pricing line with a freeze risk. Neither is gentle if the second property underperforms.

A third path deserves a look. If you own a rental with equity, a DSCR cash-out refinance keeps the leverage on the investment side. It may be subject to lender program eligibility on vesting and property type. The strongest approach for many investors is to size equity from whichever property can carry it best.
