The Quick Read: A HELOC adds a second loan behind your first mortgage and prices only the new money, while a cash-out refinance replaces the first mortgage with a larger one, so the better choice usually turns on how much cash you need, who holds title, and whether your current first mortgage is worth keeping. Across the wholesale network Lendmire places files with, the two paths are underwritten very differently. A HELOC is judged on you. A DSCR cash-out refinance is judged mainly on the rental.
- A HELOC on an investment property tops out at 70% combined loan-to-value (CLTV) and a $500,000 line.
- A DSCR cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with loans up to $3,000,000.
- A HELOC cannot be titled in an LLC. A DSCR cash-out usually can keep the LLC, subject to lender program eligibility.
- Clearing a DSCR ratio of 1.00 does not mean the rental cash flows.
- A low first mortgage favors the line. A need for one large lump sum favors the refinance.
Key Terms Defined
HELOC: A home equity line of credit, a revolving loan secured by property that you draw on in stages.
Second lien: A loan that sits behind your first mortgage. If the property is sold in default, the first lender is paid first.
Cash-out refinance: A new first mortgage that pays off the old one and hands you the difference after costs.
CLTV (combined loan-to-value): All loans on the property added together and divided by its value.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly housing payment of principal, interest, taxes, insurance, and any HOA dues. A ratio of 1.00 means rent equals that payment.
Seasoning: The waiting period a lender wants after you buy before it will lend against the property. On DSCR cash-out files, about 6 months is the common expectation.
Draw period: The stretch of a HELOC when you can borrow, usually paying interest only.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Replace or Add: The Core Difference
A cash-out refinance replaces your first mortgage. A HELOC leaves it alone and adds a separate loan behind it. Everything else flows from that one choice.
Replacing means every dollar you owe gets repriced. Adding means only the new money carries the new loan’s terms. That is why a first mortgage you would hate to lose pushes people toward the line.
| Factor | HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Paid off and replaced |
| Underwritten to | You: credit, debts, DTI | The rental’s income |
| Title | Individual or revocable trust | LLC often fine |
| Investment-property cap | 70% CLTV, $500,000 line | About 75% LTV, up to $3M |
| Payment shape | Interest-only draw, then amortizing | One new first-lien payment |
| Best for | Smaller, staged needs | Larger, one-time needs |
The table compares typical ranges from select wholesale lenders. Every file is reviewed individually, and none of it is a commitment to lend. For a deeper side-by-side, see Lendmire’s guide Cash-Out Refinance vs a Second Lien: Choosing the Right Tool.
How a HELOC Is Underwritten, Step by Step
On the network, a HELOC file is built around the borrower, not the rent. Here is the sequence a lender follows.
Step 1: Pick the lien position. The line can sit in first or second position. For an owner with an existing mortgage, it is almost always a second lien behind the first.
Step 2: Size the line. Take the property’s value, multiply by the CLTV ceiling, and subtract what you already owe. On an investment property that ceiling is 70% CLTV, and lines run from $25,000 up to $500,000. A line cannot exceed that investment cap, and there is no higher tier for rentals.
Step 3: Check the borrower. Credit, existing liens, and total debt drive the decision. The minimum credit score on an investment line is 700, and the 70% ceiling applies at both the 700 and 720 tiers, so a higher score does not raise it. Debt-to-income (DTI) tops out at 50%, or 45% for scores from 600 to 679. The lender calculates it on the interest-only payment at the maximum draw, not on what you plan to borrow.
Step 4: Value the property. Lines at or below $500,000 ordinarily run on an automated valuation with no traditional appraisal. You can still request a full appraisal.
Step 5: Close and draw. At least 75% of the line is drawn at closing. That surprises people who picture a HELOC as a standby reserve. On this network it works more like a loan with a small amount of extra room.
Step 6: Draw period, then repayment. Investment lines use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats the whole time and never converts to fixed. Market surveys describe a longer norm, a 10-year draw followed by up to 20 years of repayment. The network’s investment structure is the 5-year draw and 25-year repayment described here.
Rental-property lines are a narrow product everywhere. Market surveys note that the lender pool is smaller, borrowing limits are lower than on a primary home, and lenders treat default risk as higher on rentals. That matches what a broker sees: fewer lenders, tighter caps, stricter files.
One more practical limit applies. HELOC placements run in 16 full-service states, which is narrower than the 41-market DSCR footprint. Availability for your property depends on where it sits.
How a DSCR Cash-Out Refinance Works
A DSCR cash-out refinance reads the rental’s income. 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.
The mechanics look like this:
1. The new first-lien loan pays off the old mortgage, and you keep the remainder after costs. 2. The lender usually wants about 6 months of seasoning. 3. A full appraisal with a rent schedule establishes value and market rent. 4. The lender tests whether rent covers the new, larger payment. 5. The paperwork shifts to the property: rent documentation, appraisal, entity papers, and reserve statements.
Leverage on a cash-out refinance tops out around 75% LTV on a standard rental across most of the network. On short-term-rental collateral, a cash-out refinance tops out at 70% LTV. Loans generally reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Above $2,500,000, the network generally holds to 30-year fixed structures.
Coverage matters more here than on a HELOC. Many select programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and more leverage.
Credit works in tiers. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage. Reserves vary by lender, leverage, loan size, and transaction type. About 6 months of PITIA (principal, interest, taxes, insurance, and HOA dues) is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Larger loans typically step up to about 9 months.
Qualification here runs primarily on property-level rental income covering the payment, subject to lender guidelines. For the broader picture, Lendmire’s complete DSCR loans guide walks through the full program.
How Much Can You Actually Pull Out?
The arithmetic is the same on both paths: value times the leverage ceiling, minus what you owe. The CFPB’s HELOC booklet frames equity as value minus what you owe and notes you can typically borrow only a percentage of it.
Run this as a modeled example in percentages of value. Say a rental has a first mortgage equal to 40% of its value.
- HELOC on an investment property: The 70% CLTV ceiling leaves room for about 30% of value. The $500,000 line cap may bind first on higher-value properties.
- Cash-out on a standard rental: A new first lien at around 75% LTV leaves about 35% of value before costs. The loan can run higher in dollars than a HELOC allows.
- Cash-out on a short-term rental: At 70% LTV, the same math leaves about 30% of value.
Those figures are before closing costs and subject to appraisal and lender review. The calculator on this page can turn the percentages into illustrative dollars.
The coverage effect is where the paths diverge. Suppose the rental covers its current payment at about 1.4x, a modeled assumption. A cash-out that raises the balance sharply can pull that ratio toward 1.0x, or below. The HELOC leaves the first loan’s ratio alone. It adds a second payment the DSCR formula never sees, so portfolio coverage still weakens.
The ratio also compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Clearing 1.00 is not the same as positive cash flow.
Where the General Rule Breaks
Most of the surprises show up at the edges. These are the named cases to check before choosing.
An LLC holds title. A HELOC on this network requires an individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is lender product design, not a federal ban. A DSCR cash-out usually keeps the LLC, subject to lender program eligibility.
Re-titling out of an LLC to qualify for a line. This can trigger a due-on-sale clause and weaken liability protection. Talk to your attorney and lender before moving title.
A duplex where you live in one unit. The lender reviews it as a primary residence, which opens the higher primary-residence ceilings. Rent both units and it becomes an investment-property file with the 70% CLTV ceiling.
A short-term rental. The lender pool shrinks, and many second-lien programs accept long-term rentals only. DSCR cash-out on short-term-rental collateral stops at 70% LTV. It generally expects a 640 or better score and about 12 months of hosting history. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
A paid-off property. A cash-out on a free-and-clear rental is simply a new first-lien loan with no payoff step.
An existing second lien when you refinance the first. The junior lender must agree to subordinate, meaning step back behind the new first loan. It has no obligation to. That is a real obstacle if you ever plan to refinance around a HELOC.
A frozen line. The CFPB notes that lenders can decline further draws if the home’s value falls significantly or your finances change. A line you are counting on may not be there when you need it.
Property type. The HELOC covers single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible. DSCR loans in the network do not offer manufactured homes, log homes, or barndominiums either.
Portfolio size. A borrower can hold at most three HELOCs, and owning more than 15 financed properties makes a borrower ineligible. A growing portfolio also pushes personal DTI up, which can limit a line well before the property does.
Past credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, foreclosure history follows a 7-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows a 4-year path.
Which One Fits?
This is where an honest broker lays out the tradeoffs. The choice is rarely obvious, and sometimes it is a genuine toss-up.
Lean toward the HELOC when:
- Your first mortgage is one you do not want to replace.
- You need a moderate amount, well inside the $500,000 cap.
- Your personal credit and DTI are strong, with a 700 or better score.
- Title sits in your own name or a revocable trust.
- You plan to buy or rehab and refinance later into a long-term DSCR loan.
Lean toward the cash-out when:
- You need a large lump sum, or more than the line cap allows.
- The rent comfortably covers the larger payment.
- Title sits in an LLC.
- Personal DTI is stretched by the size of the portfolio.
- You want one payment instead of two.
Sequencing deserves a word of caution. Many investors open a line, use it to buy or rehab, then refinance into a long-term DSCR loan. That exit depends on the refinance clearing. The property has to appraise, rent has to cover the new payment, and the junior lender has to cooperate. Keep a plan B.
Payment risk is the other half of the picture. HELOC payments float. They start interest-only and step up sharply when the draw period ends and repayment begins. The CFPB also warns that you could lose your home if you cannot repay a HELOC on schedule. On an investment property, the risk falls on the rental and on whatever else you have pledged. Borrowing against a primary home to buy a rental is not safer. Either option puts the primary residence at risk.
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.
A larger down payment or more equity does lift coverage and lower the payment. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Frequently Asked Questions
Can I get a HELOC on a rental property?
Yes, but through a narrow set of lenders. On an investment property, the network’s line runs from $25,000 to $500,000 at up to 70% CLTV with a 700 minimum score. Title must be in your name or a revocable trust. Approval depends on lender guidelines and full file review.
Is a HELOC better than a cash-out refinance if I have a low first mortgage?
Often, yes. A HELOC prices only the new money, while a cash-out reprices the whole balance. The tradeoff is a floating payment and a smaller cap. If you need a large amount, a cash-out can still make sense.
Does a HELOC count against my DSCR?
Not directly. The ratio compares rent to the first mortgage’s PITIA. But the HELOC payment is a real cost, so portfolio coverage and your personal DTI both weaken. Count both payments when judging whether the rental can carry the debt.
Can I use a HELOC if my rental is in an LLC?
Not on this network, because an LLC cannot hold title on the line. You would need to change vesting, which carries due-on-sale and liability risks. A DSCR cash-out refinance is the usual alternative, subject to program terms.
How much of the line do I have to draw at closing?
At least 75% on this network. That means the line works more like a loan with some reserve than a standby fund. Market HELOCs are generally more flexible, so check the terms before assuming otherwise.
