The Quick Read: You can borrow against a rental’s equity with a home equity line of credit, and on Lendmire’s wholesale network that means a line of up to $500,000 at 70% combined loan-to-value on an investment property, with a 700 credit score and title held by an individual or revocable trust. The lender reads you, not the rent. That makes this a different tool from a DSCR loan, which reads the property. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
- Leverage is capped low. An investment property line tops out at 70% CLTV, and credit above 700 does not raise that cap.
- It is a personal-credit product. Your credit score, income, and debt-to-income ratio decide eligibility.
- Title matters. An LLC cannot hold title on these lines.
- The line is not a standby reserve. At least 75% of it is drawn at closing, and the payment floats.
- Your first mortgage stays put. That is the main reason to choose a line over a cash-out refinance.
What Is a HELOC Against a Rental Property?
A home equity line of credit (HELOC) is a revolving credit line secured by property. You borrow what you need, repay, and borrow again within a limit. When the rental is the collateral, the lender takes a lien on that rental instead of your home.
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.
NerdWallet compares the structure to a credit card backed by the property. It describes a draw period of typically 10 years with variable, usually interest-only payments, followed by a repayment phase of up to 20 years. That is the general market shape.
The investment-property line Lendmire places through its wholesale network is tighter. It runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both phases and never converts to a fixed payment.
Experian calls rental-secured lines less common than owner-occupied ones. The reason is simple. A lender holding a second claim on a rental sits behind the first mortgage and depends on a landlord who has other costs to cover. Fewer lenders offer the product, and those that do cap it tightly.
How Underwriting Treats It, Step by Step
Underwriting a rental HELOC follows seven steps, and none of them look at the property’s rent. The file is built around the borrower and the equity. Here is the sequence a lender works through.
1. Equity test. The lender takes the property’s value, applies the allowed CLTV percentage, and subtracts every existing lien. What remains is the room for the line.
2. Valuation. A line at or below $500,000 ordinarily uses an automated valuation instead of a traditional appraisal. A higher CLTV may require a secondary valuation, and a borrower can always ask for a full appraisal. Because an investment line caps at $500,000, it sits in that automated lane.
3. Credit review. A single-bureau score model keys to the primary wage earner. The report must be no more than 90 days old at closing, and rescores are not allowed.
4. Debt-to-income (DTI). Maximum DTI is 50%. The lender reviews your file on the interest-only payment calculated as if the line were fully drawn.
5. Title and vesting. The property must sit in the name of the individual borrower or a revocable living trust.
6. Lien position. The line can sit in first or second position. Behind an existing first mortgage, it is paid second if a foreclosure ever happens.
7. Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path after a foreclosure and 4 years after a deed-in-lieu, pre-foreclosure, or short sale.
Notice what is missing. Nobody divides rent by the payment. A rental that loses money every month can still carry a HELOC if your personal income and credit are strong, and a rental that cash flows beautifully can be declined if your DTI is stretched.
How Much Can You Actually Borrow?
On an investment property, the most you can reach is 70% combined loan-to-value (CLTV), which adds every lien on the property together and compares the total to its value. That ceiling applies at 700 credit and at 720 credit alike, and the line itself never exceeds $500,000.
Here is the math in percentages. Say a rental has a first mortgage at 55% of its value. At a 70% CLTV cap, the room for a line is about 15% of value. If the first mortgage already sits at 70% or higher, there is no room at all. The CFPB’s HELOC booklet walks through the same value, percentage, and balance subtraction using a sample home.
Market surveys often report higher caps for equity lines, but those describe the broader market. They are not what an investment property reaches on this network. The table below keeps the occupancy attached to each number, because mixing them up can lead borrowers to misjudge their room.
| Factor | Investment property line | Primary residence line |
|---|---|---|
| Maximum CLTV | 70% | Up to 90% (720+ credit only) |
| Minimum credit | 700 | 600 program floor |
| Line size | $25,000 to $500,000 | Up to $750,000 |
| Draw structure | 5-year draw, 25-year repay | 3-year or 5-year draw options |
| Valuation | Automated, commonly no appraisal | Full appraisal above $500,000 |
A primary-residence line above $500,000 caps at 75% CLTV and requires a full appraisal. Credit for a line above $500,000 must be 700 or better (720 on the longer-runway structure, the one with the 5-year draw and 25-year repayment). The 90% figure exists only at a 720 profile, and it never applies to a rental.
Key Terms Defined
Junior lien: a claim on the property that gets paid after the first mortgage if the property is sold in foreclosure.
Draw period: the stretch of time when you can take money out of the line, usually paying interest only.
Repayment period: the stretch after the draw ends, when borrowing stops and principal plus interest are due.
Automated valuation: a computer-generated property value used instead of a traditional appraisal.
Vesting: the legal name on the property’s title, such as an individual, a trust, or an LLC.
PITIA: principal, interest, taxes, insurance, and any HOA dues, the full monthly obligation a DSCR loan measures rent against.
The Structure Is Not a Standby Line
Many borrowers imagine a rental HELOC as a zero-balance cushion they tap once a roof fails. On this network, that is not the product. At least 75% of the line is drawn at closing, so you start borrowing most of it on day one.
That changes the math you should run. You are not buying optionality. You are taking a term loan with a little borrowing room left over. After closing, you can still draw against what remains, though subsequent-draw minimums apply.
The draw period then ends, and the payment shifts. The CFPB’s HELOC explainer notes that borrowing stops when repayment begins and that some plans can demand the whole balance at that point. It also says lenders often schedule repayment over ten or 20 years.
Consumer sources agree the payment commonly rises materially when interest-only ends, but the size depends on the balance and the market. Run the amortizing payment on the full balance before you sign, not the interest-only figure. On this network’s investment structure, the 25-year repayment means principal is spread across the full repayment term rather than arriving all at once, so the payment steps up once principal is added to interest.
The CFPB also notes that some lines convert part of the balance to a fixed payment, and that some plans can be renewed while others cannot. The investment line on this network never converts to fixed. Read your own agreement for renewal terms.
Where the General Rule Breaks
The general rule is that a rental HELOC works for an individual with strong credit and room in the CLTV table. Seven situations bend that rule.
Your rental sits in an LLC
This is the sharpest edge. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A rental already deeded to an LLC needs a vesting change before a HELOC is possible, or it needs a DSCR cash-out instead, subject to lender program eligibility.
Retitling carries its own consequences for liability protection and for your existing first mortgage. Talk through that with your attorney before moving a deed just to qualify for a line.
Your first lender has a say
The first mortgage stays in place, but its documents must tolerate a junior lien. A later refinance of that first loan needs the junior lender’s cooperation through subordination, and the junior lender is not obliged to grant it. Check your note for language on additional liens.
The property type is off the list
Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered on either structure. Modular homes are eligible on the longer-runway structure only. A 2-4 unit property needs a 640 minimum on that same structure, which the 700 investment floor already exceeds.
You own a lot of rentals
A borrower is limited to three lines in total, and combined exposure caps apply. A borrower with more than 15 financed properties is not eligible. Large portfolios usually belong in DSCR territory instead.
The line would exceed the cap
Investment lines stop at $500,000 no matter how much equity you hold. A line above that is primary-residence only.
Your credit sits between tiers
Below 700, the investment line is simply unavailable. There is no tier beneath it. Above 700, you gain eligibility but not leverage.
Availability is narrower than DSCR
Lendmire arranges DSCR investor loans across 41 markets, including Washington, D.C. HELOC lines are available only in Lendmire’s 16 full-service states, a narrower footprint.
HELOC, Second Lien, or DSCR Cash-Out?
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 loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
A DSCR (debt service coverage ratio) divides monthly rent by the full monthly obligation: principal, interest, taxes, insurance, and HOA dues. A ratio of 1.00 means rent covers that obligation exactly. Lendmire’s complete DSCR loans guide covers the full mechanics.
Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
| Factor | Rental HELOC | DSCR cash-out refinance |
|---|---|---|
| Underwritten on | Your credit and DTI | The property’s rent coverage |
| Max leverage, standard rental | 70% CLTV | About 75% LTV |
| First mortgage | Stays in place | Paid off and replaced |
| LLC title | Not eligible | Possible per program terms |
| Typical credit floor | 700 | 620 in parts of network; most want ~660 |
A DSCR cash-out refinance on a standard rental tops out around 75% LTV, and 70% on short-term-rental collateral, with about 6 months of seasoning commonly expected. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Reserves vary by lender, leverage, loan size, and transaction type, and are commonly around 6 months of PITIA.
A cash-out refinance raises the first-lien balance, which pushes the coverage ratio down. A HELOC leaves the first loan alone but adds a second payment. For owners who want equity without touching the first loan, Lendmire also covers DSCR second lien for rental owners who want equity without refinancing.
What the Decision Looks Like in Practice
Three investors show how the choice usually sorts itself out.
Picture an owner with a single duplex in their own name and a first mortgage they like. Their first loan sits at roughly half of the property’s value, and their credit is above 700. A HELOC fits. The first loan survives, and the CLTV table leaves room.
Consider a second owner holding four rentals inside an LLC. Rent coverage on each runs near 1.2x, but the LLC blocks a HELOC outright. A DSCR cash-out on the strongest property is the cleaner path, because the loan reads the property and accepts entity titles under program terms.
Run the numbers on a third owner whose first mortgage already sits near 70% of value. The HELOC has no room. A cash-out refinance may fit if the first loan carries no prepayment penalty, or the owner may need to wait for the balance to fall.
Two risks deserve plain language. First, the lien attaches to the rental, so default puts that rental at risk. Experian notes the primary home is typically not at risk unless the lender requires additional collateral or a personal guarantee. Second, if you put the lien on your primary home instead to fund a rental purchase, that home becomes the collateral. Primary-home lines usually carry roomier CLTV tables, but they also carry that exposure.
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.
Every file is underwritten individually, and a line is never a commitment to lend until a lender approves it. Before applying, gather your first-mortgage statement, a current insurance declaration, rental agreements, and proof of income.
Compare Your Options With Lendmire
If you are considering a home equity line 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. Lendmire also arranges DSCR financing through select lenders when title, entity structure, or portfolio size rules out a line.
Frequently Asked Questions
Can I get a HELOC on a rental property owned by my LLC?
Not through this network’s investment lines. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change to an individual or revocable trust, or a DSCR cash-out refinance instead, subject to program terms. Check with an attorney before retitling.
How much equity can I borrow against on a rental?
Up to 70% combined loan-to-value on an investment property, capped at a $500,000 line. Subtract your existing mortgage balance from that percentage of value to see your room. Credit above 700 does not raise the cap, and a rental that already carries heavy debt may leave no room at all.
Does the payment change after the draw period ends?
Yes, and it usually rises. The draw period is interest-only, then principal repayment begins. On the investment line here, a 5-year draw is followed by a 25-year repayment. Pricing floats throughout and never converts to fixed, so size your cash flow against the amortizing payment.
Will a HELOC on a rental affect my first mortgage?
The first mortgage stays in place, but its documents must allow a junior lien. A later refinance of that first loan needs subordination from the junior lender, who is not required to grant it. Review the language in your note before adding a second claim.
Should I choose a HELOC or a DSCR cash-out when I want to keep my first mortgage?
A HELOC keeps the first loan intact, so it fits when that loan is one you want to hold and your personal credit and DTI are strong. A DSCR cash-out replaces the first loan, and it fits when the property’s rent coverage is stronger than your personal profile. The decision usually turns on title, leverage, and portfolio size.
