The Quick Read: The best program depends on which property secures the line, because a rental you just financed usually has too little equity left to support one, so the real choice is between a line on an older rental, a line on your home, or a DSCR cash-out refinance.
- On an investment property, the network’s ceiling is 70% combined loan-to-value (CLTV), with a maximum line of $500,000 and a 700 minimum credit score.
- CLTV counts every lien plus the full line commitment, not just the amount you draw.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on this product.
- A line on your primary residence can reach 90% CLTV, but only with a 720 or better credit profile.
- A DSCR cash-out refinance is the usual alternative when the rental sits in an LLC or the line is too small.
You just bought a rental. Now you want a credit line, either to pull your down payment back out or to fund the next deal. The answer depends on which property the lender takes as collateral, whose finances the lender reviews, and how much equity is really there.
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.
Lendmire is a mortgage broker. It works with a network of wholesale lenders that write these lines, so the match comes from your scenario, not from one lender’s menu.
What an Investment Property HELOC Actually Is
A home equity line of credit (HELOC) is a revolving line secured by a property you own. You borrow against it as needed, up to a limit, during a set draw period. On an investment property, the collateral is a rental instead of your home.
The product is narrow. The lenders that write these lines review you, not the building.
That is the sharpest difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC on a rental looks at your credit, your debt-to-income ratio (DTI), and your equity. The rent is not the test.
Here is the investment-property structure across the network:
- Line size: $25,000 to $500,000.
- Draw period: 5 years, interest-only.
- Repayment: 25 years, fully amortizing.
- Initial draw: at least 75% of the line is drawn at closing.
- Pricing: floats through both phases and never converts to fixed.
- Lien position: first or second, depending on what is already recorded on title.
Subject to lender guidelines, every figure here applies to full-file review, and none of it is a commitment to lend.
How Underwriting Treats It, Step by Step
Underwriting follows six steps. Each one can end the file, so the order matters.
Step 1: Title. The lender confirms you hold title as an individual or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a different product.
Step 2: Value. Because an investment line tops out at $500,000, and full appraisals begin only above that, these lines run on an automated valuation model. A higher CLTV may trigger a secondary valuation. You can also ask for a full appraisal.
Step 3: The CLTV test. Maximum line equals the property’s value times 70%, minus the existing first-mortgage balance. The full line commitment counts against that ceiling, even the part you never draw.
Step 4: Credit and DTI. The investment-property floor is 700, and a 720 score buys no extra leverage on an investment line. Maximum DTI is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, so a large line can raise your DTI even if you plan to draw little.
Step 5: Property eligibility. Single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Step 6: Portfolio limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
Why a Rental You Just Bought Rarely Supports Its Own Line
The CLTV ceiling is 70% on an investment property, and that is where the math usually breaks. A typical purchase loan sits at 75% to 80% LTV, and select programs reach 85% LTV with roughly a 700+ score. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Run it as percentages. You buy a rental at 75% LTV. The first mortgage already exceeds the 70% CLTV ceiling, so the room for a line on that property is zero. At 80% or 85% LTV, you are further over. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The new rental can support a line only when value rises, the balance falls, or you bought it with cash. A cash purchase leaves the property free and clear. The line then takes first-lien position, and the line alone sets the CLTV.
Try a different picture. You own an older rental with a first mortgage equal to 50% of its value. At the 70% ceiling, the room is about 20% of value, before the lender’s other checks. An older property with a seasoned balance often does the job the new one cannot.
Whether a lender wants some time to pass after a purchase before lending on it varies by program. Ask before you plan around it.
Which Property Should Secure the Line?
You have three realistic collateral choices, and each carries a different risk.
| Factor | Line on an investment property | Line on your primary residence | DSCR cash-out refinance |
|---|---|---|---|
| Max leverage | 70% CLTV (investment) | 90% CLTV, 720+ only (primary) | About 75% LTV (standard rental) |
| Underwritten on | You: credit, DTI, equity | You: credit, DTI, equity | The property’s rent coverage |
| First mortgage | Stays in place | Stays in place | Replaced |
| Pricing | Floats | Floats | Fixed spine available |
| Collateral at risk | The rental | Your home | The rental |
On short-term rentals, DSCR cash-out tops out around 70% LTV instead. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The primary-residence line gives you the most room. The cost is that your home backs money used to buy an investment. A default on any HELOC can lead to foreclosure on the secured property, and Benzinga’s explainer on using a HELOC to buy a house makes the same point about rental purchases. Weigh whether you are willing to put your home at risk for an investment.
Using the Proceeds as Your Next Down Payment
The HELOC lender does not restrict how you spend the money. The lender financing your next purchase does decide how it treats borrowed funds.
Down payment, closing costs, and reserves are three separate buckets. Many purchase programs accept documented borrowed funds for the first two. Reserves are often treated more strictly, so ask the purchase lender how it counts a drawn line.
Pull the line before you apply for the next purchase loan, not after. The draw then shows up as a documented source of funds, and the new payment is already in your numbers.
Be honest about leverage. A purchase funded entirely by a line leaves you owning a property with almost no equity of your own. The Benzinga explainer notes that a HELOC can fund a rental purchase. That does not make it safe to finance nearly 100% of one.
The Payment Shock Nobody Models
The line has two phases, and the second one is the dangerous one. During the 5-year draw, you pay interest only. When repayment starts, the balance amortizes over 25 years, and principal joins the payment. Same balance, higher monthly obligation.
Pricing floats the whole way. Federal consumer guidance from the CFPB on home equity lines says these plans usually carry variable pricing, so payments can change from month to month. The same page says plans that let you convert part of the balance to a fixed structure usually charge more for that certainty. On this network, an investment line never converts.
The CFPB’s HELOC booklet adds that a variable-pricing payment can change even if you draw no more money. It also gives a shopping checklist covering how often pricing adjusts, the cap and floor, and the length of the draw and repayment periods.
Because at least 75% of the line is drawn at closing, interest starts building on day one. You are paying for most of the line whether or not you need it.
Stress-test before you sign. Whichever property secures the line, check that the rent on the new rental still covers its own mortgage, and that your cash flow still covers the line payment if pricing rises. Check again at the start of the repayment phase. Your DSCR on the new purchase loan compares rent only to its own principal, interest, taxes, insurance, and any HOA dues. It ignores the line, and your bank account does not.
Where the General Rule Breaks
Several edge cases change the answer.
The rental is in an LLC. The HELOC path closes unless you re-vest title in your own name or a revocable trust. Moving title can trigger questions with your existing lender and title insurer, so check both first. The alternative is a DSCR cash-out refinance, which can often be written to an LLC, subject to lender program eligibility.
You need more than $500,000. An investment line stops at $500,000. A line above that is available on primary residences only, caps at 75% CLTV, and requires a full appraisal.
You want to keep a low first mortgage. A second-lien line leaves the first loan untouched. A cash-out refinance replaces it. If your existing loan has favorable terms, that difference can decide the whole question.
The rental is free and clear. The line takes first-lien position. Credit and DTI still apply, but the lien math is simple.
A divorce is pending. A pending case can restrict new liens and may require spousal consent or a court order.
The property type is off the list. Manufactured homes, log homes, and barndominiums are not offered on the network’s DSCR programs, and the HELOC product has its own ineligible list, covered above.
You already own many properties. The 15-financed-property cap and the three-line limit can end the file before credit matters.
When a DSCR Cash-Out Refinance Wins
A DSCR cash-out refinance replaces your existing loan and qualifies primarily on rental income covering the payment, subject to lender guidelines. It tops out around 75% LTV on standard rentals, and about 6 months of seasoning is the common expectation. Credit typically needs around 660 on most programs, with a 620 floor in parts of the network and 700+ unlocking the strongest tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).
Coverage matters here. A 1.00 DSCR is where select programs start, not a universal standard, and stronger coverage opens better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Terms can also include extended 40-year structures, interest-only periods, or ARM options through select lenders.
Reserves vary by lender, leverage, loan size, and transaction type. About 6 months of PITIA (principal, interest, taxes, insurance, and HOA) is common, conservative rate-and-term files under $1,500,000 can see reserves waived, and larger loans typically step up to around 9 months.
Clearing 1.00 does not mean the property produces positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
The complete DSCR loans guide covers the underlying program mechanics.
What the Decision Looks Like in Practice
Ask five questions, in this order.
1. How is the property titled? An LLC points you to DSCR cash-out. An individual or revocable trust keeps the line available.
2. Where is the equity? If the new rental is financed near 75% to 80% LTV, the equity is elsewhere: an older rental or your home.
3. Do you want to keep the first mortgage? If yes, the second-lien line has the edge. If the existing loan is not worth protecting, cash-out gives higher leverage and a fixed spine.
4. How big is the need? Above $500,000, an investment line is off the table.
5. What is your exit? Plan to repay the line through a refinance, a sale, or cash flow. Do not count on a single route. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The honest tradeoff is straightforward. The line is flexible, and it floats. The refinance resets the loan, and it fixes the structure. Neither is better in the abstract. This is a genuine toss-up for investors with a good first mortgage and modest needs, and it tilts toward cash-out as the amount and the equity grow.

Frequently Asked Questions
Can I open a HELOC on a rental I just bought?
Sometimes, but the equity is usually missing. A purchase loan at 75% to 80% LTV already exceeds the 70% CLTV ceiling on an investment property. The line becomes possible after value rises or the balance falls, or when you bought with cash. Lender treatment of recent purchases varies, so ask before you plan around it.
Does a higher credit score raise my leverage on an investment line?
No. On the network, 700 and 720 both reach the same 70% CLTV on an investment property, up to $500,000. Credit above 700 buys eligibility, not extra leverage. The 90% CLTV figure applies only to primary-residence lines with a 720 or better profile.
Can my LLC take out the line?
No. Title must be held by an individual or a revocable living trust. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead, which can often be written to an LLC, subject to lender program eligibility.
Does the new rental’s rent count toward qualifying for the line?
No. The line is reviewed on your credit, DTI, and equity, not on rent. A DSCR loan works the opposite way. Even so, your own cash flow still carries the line payment, so test both.
Is the best program the one with the highest leverage?
Not usually. The best program for your situation balances title, equity location, line size, and how much floating exposure you can carry. Highest leverage is also where payment shock and thin equity cost the most.
