How Much a Cash-Out Refinance Costs Versus a HELOC on a Low Mortgage

The Quick Read: On a low first mortgage, a HELOC often costs less to open than a cash-out refinance, because it leaves the old loan in place and prices only the new money, while the refinance replaces the whole balance and pays closing costs on a larger loan. On an investment property, though, the line has tight limits: it tops out at 70% CLTV and $500,000, and the property cannot sit in an LLC. The right pick depends on how the property is titled, how much cash you need, and how much the old loan is worth keeping.

• A cash-out refinance pays off the first mortgage, so its terms are gone. A HELOC sits beside it.
• A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC is underwritten on the borrower.
• On an investment property, the network’s line ceiling is 70% CLTV with a 700 minimum credit profile. Cash-out on a standard rental tops out around 75% LTV.
• LLC-held rentals generally point to the refinance. The lines require individual or revocable-trust title.
• Fees, old-loan prepayment charges, and the recalculated coverage ratio decide the real cost, not the product name.

The honest answer: pick the refinance when the old loan has little worth protecting, the cash need is large, or the title sits in an entity. Pick the HELOC when the old loan is a keeper, the cash need is modest, and the property is held personally. Lendmire’s wholesale network places both products, and the table below uses the network’s own guidelines. Every figure is subject to lender guidelines, and eligibility is reviewed file by file.

Side-by-Side

The two products differ most on who gets underwritten, what happens to the first mortgage, and who can hold title. Pricing is not compared here. It lives in the calculator and moves with every file.

The leverage figures in the table apply to different transactions. The 75% is a cash-out refinance LTV on a standard investment property. The 70% is a CLTV on an investment property line, and it counts the first mortgage plus the line. The line also needs a 700 minimum credit profile. Cash-out refinance credit floors run lower: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest tiers.

Reserves are the soft spot in this comparison. On the refinance side they vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common, conservative files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months. On the HELOC side, the lender sets reserves file by file, so confirm them before anyone orders a valuation.

Two property rules apply to both products. Manufactured homes, log homes, and barndominiums are not offered. The HELOC also excludes co-ops, condotels, commercial, mixed-use, and agricultural zoning. Single-family, 2-4 units, PUDs, townhomes, and condos (non-warrantable included) are eligible on the line.

What “Cost” Means on a Low First Mortgage

Cost here is mostly structural. The question is what you give up, what comes out of proceeds, and how much cash you can actually reach. A cash-out refinance reprices the entire balance, including the part you were happy with. A HELOC touches only the new money.

The Consumer Financial Protection Bureau describes a HELOC as a line you can draw on repeatedly up to a maximum, with credit replenished as you repay. It also notes that on a property with a mortgage, the line is a second mortgage paid on top of the first. Its HELOC booklet adds that a cash-out refinance replaces the existing mortgage, and that refinance closing costs are generally higher than those on a second mortgage.

That matches what shows up in files. The refinance carries four cost lines that the line mostly avoids.

1. Repricing of the old balance. The first mortgage’s terms are gone, however favorable they were.

2. Closing costs on the larger loan. They come out of proceeds, so net cash is the new loan, minus the old payoff, minus costs.

3. Prepayment charge on the old loan. If the existing first is a DSCR loan with a step-down window still running, the charge comes out of proceeds too. Ask for the payoff statement early, before the numbers are final.

4. A new prepayment schedule. The new loan usually carries its own, and the schedule is program-specific.

The HELOC has its own costs, and they are not small. The network’s investment line requires at least 75% of the line drawn at closing. That means you carry interest on most of the line from day one, whether or not you need the cash yet. The payment floats through both the draw and repayment periods and never converts to fixed. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. When the repayment period starts, the payment steps up. Size that step-up before you commit.

Analysts at the Urban Institute make the same point: a second lien lets a borrower keep a low first-lien while tapping equity. They also note that limited securitization of second liens constrains supply. That supply constraint shows up on investment collateral, which is why the line is narrower than the refinance.

When a Cash-Out Refinance Is the Better Fit

The refinance wins when the old loan has little left to protect, the cash need is large, or the title is already in an entity. It is also the product that is reviewed on the property instead of the person.

The title sits in an LLC. The HELOC programs here require fee simple or leasehold held by an individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead. The DSCR route generally handles entity-held rentals, subject to program terms.

The cash need exceeds the line cap. The investment line stops at $500,000 total. A larger need pushes toward the refinance, which runs up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.

Personal debt is the binding constraint. The HELOC is underwritten against a debt-to-income ratio capped at 50%. It is qualified on the interest-only payment calculated as if the line were fully drawn. An investor with several financed properties can hit that wall long before the rents run out. The DSCR refinance tests the property’s rent against its own payment, so the personal ratio is not the main gate. A borrower owning more than 15 financed properties is not eligible for the line at all.

The old first mortgage isn’t worth much. If the existing loan is adjustable, or its advantage is small, the repricing cost shrinks and the refinance gets simpler. It also buys cleaner structure options: select lenders in the network offer extended 40-year terms and interest-only periods, and ARMs exist for investors who want them.

Seasoning is already satisfied. About 6 months of ownership is the common expectation for cash-out. Files that assume the seasoning requirement away get kicked back. The settlement statement documents the purchase date.

Coverage math changes with a refinance, and that catches people. The DSCR ratio is rent divided by PITIA, which means principal, interest, taxes, insurance, and any HOA dues. A bigger loan means a bigger payment, so coverage drops. 1.00 is where select programs start, and stronger ratios open better leverage and terms. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 is also not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation.

When a HELOC Is the Better Fit

The line wins when the first mortgage is worth keeping, the cash need is modest, the property is held personally, and the borrower’s file is strong. It also suits phased needs, such as rehab draws or acquisition money drawn in stages.

CBS News covers the same logic in its comparison of the two options: with a low first mortgage, a line lets the first stay in place so only incremental funds are borrowed. For an investor, that is the entire argument, and it is a sound one when the line is available.

Several conditions have to line up. The property sits in a state where the network places investment lines, which means one of 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the DSCR footprint, which covers 40 states plus Washington, D.C. The borrower holds a 700 or better credit profile. The property is not listed for sale, or listed within the past 60 days, in NC, PA, TN, TX, or WA, where that makes it ineligible. And the borrower stays within three lines total.

Valuation is lighter on the line. At or below $500,000, lines ordinarily run an automated valuation with no traditional appraisal. A borrower can still ask for a full appraisal, and a higher CLTV may call for a secondary valuation. The refinance is appraisal-driven.

The HELOC also keeps the old loan’s prepayment exposure out of the picture. If the first is a DSCR loan inside its penalty window, leaving it in place can save real money. That alone can decide the question.

One more route comes up often: a line on the investor’s own home, with the proceeds deployed into rentals. That follows primary-residence tiers, which run higher than investment tiers. The ceiling reaches 90% CLTV only at a 720 or better credit profile, up to $500,000, and lines above $500,000 are primary-residence only. It also puts the investor’s home behind the rental purchase, which is a different risk than a line on the rental itself. Weigh it as a separate decision.

A Worked Comparison, in Percentages

Take an investor holding one rental personally, with a first mortgage at about 50% of the property’s value and 700-plus credit. These are modeled assumptions, not market data.

On the line, the investment ceiling is 70% CLTV. That leaves roughly 20 points of value available, before the $500,000 cap and before the requirement that at least 75% of the line be drawn at closing. The first mortgage stays untouched.

On the refinance, the cash-out ceiling on a standard rental is around 75% LTV. The old loan is gone, and the whole balance is repriced. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

So the refinance reaches more equity on paper, while the line leaves more of the existing structure intact. Which wins depends on three checks run in this order.

1. Is the title individual or trust? If not, the line is off the table.

2. Does the rental still cover both obligations? Run rent against the old payment plus the line’s payment on one side, and rent against the single new payment on the other. A file that lands barely above 1.00 after the new debt leaves little room.

3. What does the payoff statement say? A prepayment charge on the old loan can erase the refinance’s extra reach.

If coverage falls short on the refinance, a select-lender path below 1.00 exists, with leverage and terms adjusted. Qualification stays subject to lender guidelines, credit approval, and property review.

Where These Files Break

Most problems on these files are preventable documentation gaps, not underwriting surprises.

• Vesting mismatch. The investor assumes a line is possible, and the deed shows an LLC. Check title first. It saves a full file build.
• Payoff statement ordered late. The prepayment charge on the old loan surfaces after the borrower has already committed to a net-cash number.
• DTI measured on a fully drawn line. Borrowers expect the ratio on the amount they plan to draw. The qualifying payment is calculated on the maximum draw.
• Listed or recently listed property. In the five states with the listing rule (NC, PA, TN, TX, and WA), a property listed within the past 60 days is ineligible for the line.
• Entity papers incomplete on the refinance. Operating agreement, EIN letter, and good-standing evidence should be in the file before anyone asks.
• Rent evidence thin. The refinance is reviewed on rent, so the lease or the appraisal’s rent schedule has to be clear and current.

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

Neither product is cheaper in every case. The refinance costs more when the old loan has good terms, because it reprices everything. The line costs less when it is available, but on investment property its limits are tight. They are the 70% CLTV ceiling, the $500,000 cap, the 700 credit floor, the 75% drawn at closing, the floating payment, and the ban on LLC title.

A short rule of thumb: if the property is personally held, the first mortgage is worth keeping, and the cash need fits under the cap, price the line first. If the title is an entity, the cash need is large, or personal debt ratios are the problem, price the refinance. Either way, the strongest files clear two tests: enough equity and enough rental coverage.

DSCR programs are built for business-purpose investor loans, so the refinance is reviewed differently from an owner-occupied mortgage. The complete DSCR loans guide covers the full program. For a closer look at the refinance side, Lendmire’s piece How Much a Cash-Out Refinance Costs Versus a Second Mortgage goes into the fee lines. The comparison of a second-lien HELOC against a cash-out refinance on a low fixed first mortgage takes the same decision from the second-lien side.

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 site’s calculator gives an illustrative estimate to start from. Lendmire brokers through select lenders in its wholesale network and is not the lender.

Key Terms Defined

CLTV: Combined loan-to-value, which adds the first mortgage and the line together and divides by the property’s value.

Draw period: The stretch when the line can be borrowed against, followed by a fully amortizing repayment period.

DSCR: Debt service coverage ratio, which compares a property’s monthly rent to its full monthly obligation (PITIA).

Seasoning: The ownership time lenders expect before allowing cash-out, documented by the settlement statement.

Lien position: Where a loan stands in line for repayment; a second lien is paid after the first if the property is sold in a forced sale.
