Cash-Out Refinance vs HELOC for Owners With a Low First Mortgage

The Quick Read: A cash-out refinance fits owners who want one large lump sum and whose rent covers the payment, while a HELOC fits owners who want to keep a low first mortgage untouched and can qualify on personal credit and income, on a property titled in their own name. A HELOC is a home equity line of credit, a loan secured by your property that sits alongside, or behind, your first mortgage. The deed often decides the question before any math starts.

• A cash-out refinance pays off your first mortgage and replaces it. On most files in the network it tops out near 75% LTV on standard rentals, and near 70% on short-term-rental collateral.
• An investment-property HELOC runs up to 70% CLTV (combined loan-to-value, all liens divided by value), with a 700 credit minimum and a $500,000 maximum line.
• Lines on a primary residence or second home can go higher, but the 90% CLTV tier exists only at 720 or better credit.
• A HELOC underwrites you personally, with debt-to-income up to 50%. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
• A rental held in an LLC cannot take a HELOC as the network structures it. That usually points to a DSCR cash-out.

Lendmire is a mortgage broker, not a lender. It arranges both products through select wholesale lenders, so this comparison has no product to push. Some files fit one lane cleanly, and some fit neither.

Side-by-Side

The table below lines up the two products as they are typically placed through Lendmire’s wholesale network. Every figure is subject to lender guidelines and full file review. HELOC figures here are for an investment property unless noted.

PITIA is principal, interest, taxes, insurance, and association dues: the full monthly obligation on the property. Two notes on the table. A DSCR cash-out usually expects about six months of seasoning, meaning you have owned the property that long. And a HELOC through this network is available only in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint, Washington, D.C. included.

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.

When a Cash-Out Refinance Is the Better Fit

Cash-out wins when the property is titled in an entity, when your personal income file is messy, or when you need a large amount in one move. It also wins when your existing first mortgage has little left worth protecting. The rental has to carry the loan, and the lump sum has to justify replacing what you have.

Title and vesting. A HELOC in this network is a loan to a person. The property must be held by the individual borrower or a revocable living trust. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title. A DSCR cash-out can be vested in an LLC, subject to lender program eligibility. Moving a deed out of an LLC to qualify for a HELOC gives up liability separation and can raise questions with your existing lender and insurer. Talk to an attorney before you do it.

Income picture. Many investors have strong rentals and thin traditional personal-income documentation. Depreciation, write-offs, and self-employment income shrink the number a personal-income file shows. A DSCR cash-out reads the property instead. Coverage is monthly rent divided by PITIA. Most programs we place files with start near 1.00, and stronger ratios open better terms and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Size. HELOC lines on investment properties stop at $500,000. A DSCR cash-out generally runs from about $100,000 up to $3,000,000. Above $2,500,000 the network generally holds to 30-year fixed structures. If you are pulling equity for a large acquisition or a payoff, the line cap may decide it for you.

Structure. The spine of DSCR lending is the 30-year fixed loan. Select lenders in the network also offer 40-year terms and interest-only periods. ARM structures exist for investors who want them. Our complete DSCR loans guide walks through the full menu.

The cost. The old first mortgage goes away, and its terms go with it. For an owner with a low first mortgage, that is the central price of cash-out. You are not only borrowing new money. You are reopening the entire balance on new terms, including the money you already owe.

Credit still matters. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage. Clearing 1.00 is also not the same as positive cash flow. DSCR compares rent to PITIA only, so repairs, vacancy, management, utilities, and capex sit outside the number.

When a HELOC Is the Better Fit

A HELOC wins when the first mortgage is worth protecting, the title is personal, and your own credit and income file is clean. It adds a lien on top of what you have. It does not rewrite it.

You keep the first loan intact. Only the new money gets new terms. A HELOC leaves your existing first mortgage as it is, and the first loan’s balance, not its terms, enters the sizing of the new line. The lower your balance, the more room you have under the CLTV cap. That is the central advantage for an owner with a low first mortgage.

Your personal file is strong. The network’s HELOC reads credit and debt-to-income, up to 50% maximum, and is reviewed around the interest-only payment calculated on the maximum draw. Credit profiles from 600 to 679 are held to 45%. On an investment property the credit minimum is 700, so this lane is narrower than it looks.

The amount fits under the cap. Lines up to $500,000 ordinarily run on automated valuation, with no traditional appraisal, though a higher CLTV may call for a second valuation. You can also request a full appraisal in any case. If you need less than $500,000 and the equity is there, the HELOC lane is straightforward.

Occupancy changes the ceiling. Investment lines top out at 70% CLTV. Second-home lines reach 90% CLTV only at 720 or better, and 85% at 700 or 680. Primary-residence lines reach 90% CLTV only at 720 or better and up to $500,000, and 85% down to a 660 score. Lines above $500,000 are primary-residence only, require 700 or better (720 on the longer draw structure), cap at 75% CLTV, and need a full appraisal. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Be honest about the flexibility. Many people picture a HELOC as a card you swipe when needed. This network’s structure works differently. At least 75% of the line is drawn at closing. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both the draw and repayment periods and never converts to fixed. If you want to hold most of the line in reserve for phased rehab, ask how that fits before you plan around it.

Know the limits. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. DSCR financing also does not cover manufactured homes, log homes, or barndominiums.

Run the Numbers on Keeping the First Mortgage

Picture an investor with a rental owned personally, a first mortgage balance equal to 40% of value, and a goal of pulling out as much equity as the programs allow. Everything here is a modeled assumption, expressed in percentages and ratios.

• HELOC route. The investment ceiling is 70% CLTV. With 40% of value already owed, the new line can reach up to 30 points of value, subject to the $500,000 cap and a 700 credit minimum.
• Cash-out route. On a standard rental, the ceiling is around 75% LTV. The new loan could reach up to 35 points of value above the old balance, and the refinance would also pay off the old loan.
• The difference. The cash-out route offers 5 more points of leverage and no line cap at that size. In exchange, the whole balance moves to new terms. The HELOC route adds less, but it leaves the first mortgage untouched. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Now add rent coverage. If the refinance pushes coverage to about 1.05x, that clears a 1.00 start point but leaves little room. A stronger ratio means better leverage and terms. If rent carries only a ratio below 1.00, a select-lender path exists with leverage and terms adjusted. A HELOC does not test rent at all. It tests you.

Here is the practical read, and it is a toss-up on some files. When the first mortgage is very cheap and the amount needed is modest, the HELOC often wins. When the amount is large, or the title is an LLC, cash-out wins by default.

What Can Go Wrong After Closing

A HELOC payment is not a fixed obligation. The CFPB’s explainer on home equity lines of credit describes a revolving, open-end line with a draw period, and some plans set minimum draw amounts or require an initial draw. The CFPB’s HELOC brochure adds that draw-period payments may be interest-only, and that repayment can come as a set schedule or a lump-sum balloon. Both can raise the payment sharply.

On this network’s investment structure, repayment is fully amortizing over 25 years rather than a balloon. The step-up in payment still arrives. Stress-test your rent against the repayment phase, not just the draw phase.

Cash-out has its own risks. The loan resets your term, closing costs come with the new first lien, and a larger balance leaves less room for a rent dip. It also takes the first mortgage away permanently. If you later regret refinancing, you cannot get that loan back.

Layering both is possible. A HELOC behind a new first lien adds payments and lowers coverage. A HELOC on a rental also generally comes due in full when you sell, so think about your exit before you borrow.

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 to Ask Before You Pick

Run through these in order. The first one or two usually decide the file.

1. Who is on the deed? An LLC on title usually ends the HELOC lane.

2. How much cash do you need? More than $500,000 on an investment property rules out a HELOC.

3. Is your first mortgage worth keeping? If its terms are strong, protect it unless the cash-out math forces your hand.

4. Which file tells the better story, you or the property? Strong personal income points to a HELOC. Strong rent points to cash-out.

5. Can you meet the credit tier? Credit requirements for investment HELOCs vary by scenario, while cash-out has a lower entry point in parts of the network.

6. What does the repayment phase look like? Check your coverage once principal starts.

The Balanced Verdict

Neither option is better in the abstract. A HELOC is the right tool when you hold title personally, your credit is 700 or better, you need less than $500,000, and you want your first mortgage left alone. A cash-out refinance is the right tool when the property sits in an LLC, your rent tells a stronger story than your traditional personal-income documentation, or you need more than the line cap allows.

Many files land in the gap: strong rentals, personal title, a modest cash need, and a first mortgage you would hate to lose. Those lean HELOC, as long as the 70% CLTV ceiling and the 75% drawn-at-closing structure still leave you the cash you need. If they do not, the refinance may be the cost of getting there. The strongest files clear both tests: enough equity and enough coverage.

Next Step

If you are weighing a home equity line against a cash-out refinance and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The illustrative calculator on this page can give you a starting estimate. Programs change, and every file is underwritten individually, and nothing here is a commitment to lend.
