The Quick Read: You can borrow up to 70% of an investment property’s value, minus every loan already on it, capped at $500,000. That line normally sits on a property you already own, because a new purchase financed at 75% to 80% LTV leaves almost no equity beneath a 70% limit. Every figure below is subject to lender guidelines and full file review.
- The formula: value × 70% combined loan-to-value (CLTV) on an investment property, minus all existing liens.
- The dollar ceiling: an investment line runs from $25,000 up to $500,000, whichever limit binds first.
- The credit floor: 700 is the minimum, and a higher score does not raise the 70% limit.
- The catch: rental income does not qualify you for this line, and an LLC cannot hold title.
- The alternative: a DSCR loan on the new purchase qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
What Does an Investment Property HELOC Actually Let You Borrow?
A HELOC on a rental lets you borrow the property’s value times the combined-loan cap, minus what you already owe. On this wholesale network, that cap is 70% CLTV on an investment property, with a maximum line of $500,000 and a minimum of $25,000.
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.
Think of it as a pie. The lender lets total debt on the rental reach 70% of its value. Your existing mortgage uses part of that slice, and the line gets what remains.
NerdWallet’s explainer says an investment-property HELOC is harder to get than one on a primary home because lenders see higher default risk. It also reports that 80% is possible on a rental line in the broader market, while many lenders sit below 70%. Treat 80% as a market-wide statistic. On Lendmire’s network, an investment-property line tops out at 70% CLTV, with no tier above it.
Here is how the sizing plays out as a share of the rental’s value, using a first mortgage already in place:
| First mortgage (% of value) | Room for a line at 70% CLTV | Notes |
|---|---|---|
| None (paid off) | Up to 70% of value | $500,000 cap may bind first |
| 30% | Up to 40% of value | Cap binds on higher values |
| 50% | Up to 20% of value | Typical mid-life rental |
| 65% | Up to 5% of value | May fall under the $25,000 minimum |
Two limits work together. The percentage limit binds on modest-value properties. On higher-value properties, the $500,000 line cap binds before the 70% limit does. Credit is a gate, not a dial: 700 and 720 both reach the same 70%, so a stronger score buys eligibility rather than extra borrowing power.
Why Is the HELOC Usually Taken on a Different Property?
The new rental rarely has equity to borrow against. A purchase financed at 75% to 80% LTV leaves 20% to 25% in equity, which is already at or below the 30% cushion a 70% CLTV limit requires. So the line normally goes on something you already own, and you have two choices.
| Collateral | Max CLTV on this network | What is at risk |
|---|---|---|
| Existing rental (investment) | 70%, up to $500,000, 700+ credit | The rental |
| Primary residence or second home | Up to 90%, only at 720 or better | Your home |
The 90% figure exists only for primary-residence and second-home lines, and only at a 720-or-better credit profile. It never applies to an investment property. A rental line puts the rental at risk. A primary-home line puts the roof over your head at risk, and the higher ceiling is the reason investors consider it.
Lines above $500,000 exist only on primary residences. They require a 700 or better credit profile (720 on the longer-runway structure, the one with a 5-year draw and 25-year repayment), cap at 75% CLTV, and need a full appraisal. No investment line can reach that size.
How Does a Rental Line Get Underwritten?
An investment HELOC is underwritten on you: credit, debt-to-income (DTI), title, and valuation. The rent does not drive the decision the way it does on a DSCR loan, where the question is whether the property’s income covers its own payment.
The main checkpoints, in the order they usually come up:
1. Credit. The investment floor is 700. The program floor for other occupancies is 600, but investment files start higher.
2. DTI. The ceiling is 50%, and it is calculated on the interest-only payment at the maximum draw, not on what you plan to borrow. A ratio above 45% requires at least a 680 score.
3. Valuation. Lines at or below $500,000 ordinarily use an automated valuation rather than a traditional appraisal. You can request a full appraisal anyway, and a higher CLTV may trigger a second valuation. NerdWallet notes that multiple appraisals may be required in the wider market.
4. Title. Fee simple or leasehold title must be held by you personally or by an inter vivos revocable living trust.
5. Exposure. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
Most of these limits are rules of the network, not quirks of one lender. Where a market-wide range differs, the network figure above governs.
What About Rentals Held in an LLC?
An LLC-titled property cannot carry this kind of line. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on an equity line here. This is the sharpest structural difference from a DSCR loan, which can often be written to an LLC, subject to lender program eligibility.
If your rental already sits in an LLC, you have two paths. You can change the vesting to your own name or a revocable living trust before applying. Or you can skip the line and use a DSCR cash-out refinance instead.
BiggerPockets Rookie describes the opposite situation: a credit union that offered a line on investment properties, but with LLC ownership and insurance requirements the investor did not expect. Lender rules on entities differ widely, so confirm vesting before you pay for anything.
Where Do You Find a Lender, and What Is the Structure?
Few lenders offer these lines at all. BiggerPockets members discussing rental HELOCs point to local credit unions and smaller banks as the usual source, because large retail lenders often decline rentals.
Lendmire is a broker, not a lender. It arranges home equity lines through select wholesale partners, and that availability covers 16 full-service states. That is narrower than the 41-market DSCR footprint, so confirm your property’s location early.
On an investment line, the structure is fixed:
- Position: a standalone line in first or second lien position.
- Draw period: five years, interest-only.
- Repayment: 25 years, fully amortizing.
- Funding at closing: at least 75% of the line is drawn up front.
- Pricing: it floats through both the draw and repayment periods and never converts to fixed.
That last point matters for planning. The line’s cost can change, and the payment steps up when repayment begins. After closing, the minimum subsequent draw is generally $1,000.
Can HELOC Funds Be the Down Payment on the New Rental?
Yes, the line supplies cash, but it does not change the loan you qualify for on the purchase. The new mortgage keeps its own down payment, reserve, and source-of-funds rules. Source of funds simply means the documented origin of your closing cash, and a drawn equity line is a documented origin.
Down payment requirements on the purchase loan vary by lender and program. A bigger down payment lowers the monthly payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Reserves vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about nine months.
Cash drawn from the line is not available as liquid reserves once it has gone to the down payment, so size the draw with that in mind. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
What Does a Full Worked Example Look Like?
Run it as percentages. Say you own a rental with a first mortgage equal to 40% of its value. At 70% CLTV, the line can reach up to 30% of that property’s value, assuming your credit is 700 or better and the $500,000 cap has not bound.
Now say you want to buy a second rental of similar value at 75% LTV on the purchase. The down payment is 25% of that price, plus closing costs. A line of 30% of the first property’s value covers the down payment and leaves a modest cushion, though the cushion is thin once reserves enter the picture. A cleaner structure is to draw only what you need and let the remainder of the line sit undrawn, remembering that at least 75% of the line is funded at closing. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Next, stress it. During the five-year draw, the line payment is interest-only on what you have drawn. When repayment begins, the payment steps up because principal is added over 25 years. Because the line floats, that step-up is not fixed or guaranteed. Test the whole plan at the repayment-period payment, not the draw-period one.
Finally, separate two tests that investors often blur together. The coverage ratio on the new loan compares the new property’s rent to that property’s own PITIA. The equity line’s payment sits on your personal side, and it counts in DTI whenever you apply for another equity line. Clearing 1.00 on coverage does not mean positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Which Funding Path Fits Which Investor?
A HELOC is one tool among several, and the right one depends on where your equity sits and how much you need.
| Path | Typical ceiling | Reviewed on | Best fit |
|---|---|---|---|
| Rental HELOC | 70% CLTV, up to $500,000 | Credit, DTI, title | Modest draw, personal-name title |
| Primary-home HELOC | Up to 90% CLTV at 720+ | Credit, DTI, title | Larger draw, comfortable risking home |
| DSCR cash-out refinance | Around 75% LTV on standard rentals | Rent versus payment | Larger draw, LLC title, many properties |
| DSCR purchase loan | 75% to 80% LTV, 85% in select programs | Rent versus payment | The new rental itself |
A DSCR cash-out refinance, a new first mortgage that pulls equity out in cash, usually needs about six months of seasoning, which is the waiting period between buying and refinancing. If you need more than $500,000, it is usually the only route on a rental, since no higher investment-line tier exists.
For the new rental itself, a DSCR loan, short for debt service coverage ratio, qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Many select programs start at 1.00 coverage, and stronger ratios open better pricing and leverage. A separate select-lender path goes below 1.00, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence. Credit expectations vary: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs, and above $2,500,000 the network generally holds to 30-year fixed structures.
Lendmire’s complete DSCR loans guide walks through those programs in full.
When Is a HELOC the Wrong Tool?
A HELOC is the wrong tool in several situations, and spotting them early saves a failed application.
- You need more than $500,000. The investment cap is firm, and no tier sits above it.
- Your rental is in an LLC. The line cannot be written on that title until the vesting changes.
- You own many properties. Past 15 financed properties, a borrower is not eligible, and three lines is the limit.
- Your DTI is stretched. Because the line is qualified on the interest-only payment at the maximum draw, an investor with many mortgages can hit the 50% ceiling first.
- The property is ineligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. Condominiums, including non-warrantable ones, are.
- You cannot tolerate a variable payment. The pricing never converts to fixed.
Key Terms Defined
HELOC: a home equity line of credit, a revolving line secured by a property, with a draw period followed by repayment.
CLTV: combined loan-to-value, the total of all liens on a property divided by its value.
Draw period: the stretch when you can borrow from the line and pay interest only.
DSCR: debt service coverage ratio, a property’s monthly rent divided by its monthly payment.
PITIA: principal, interest, taxes, insurance, and any association dues on a property.
Source of funds: the documented origin of the cash you bring to closing.
How Should You Sequence the Steps?
Order matters here, because each step sets up the next one.
1. Open the line before you need it. Applying while you are still shopping lets you size the purchase to the real line amount.
2. Pick the collateral. Decide whether the rental or the primary home carries the lien, and understand what you are risking.
3. Confirm title. Make sure the vesting is in your name or a revocable living trust.
4. Size the draw. Cover the down payment, closing costs, and reserves, remembering the 75% funded-at-closing rule.
5. Document the funds. Keep the draw and its path to closing cash easy to trace.
6. Apply for the purchase loan. The new loan carries its own rules, and the line does not move you into a different tier.

Frequently Asked Questions
Can I get a HELOC on a rental property at all?
Yes, though few lenders offer one. On this network, an investment line requires a 700 credit score and reaches 70% CLTV, up to $500,000, with title in your name or a revocable living trust. Availability through the network covers 16 states, and every file is reviewed individually, so eligibility is never assured. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Does a higher credit score let me borrow more on a rental line?
No. Investment lines have only two credit tiers, 700 and 720, and both reach 70% CLTV. A better score improves eligibility but not leverage. The only way to a higher CLTV is a different occupancy, such as a primary residence, where 90% is available only at 720 or better.
Will lenders count rental income toward qualifying?
Not on this network. An investment line is underwritten on credit, DTI, and title, not on the property’s rent. A DSCR loan works the opposite way, qualifying primarily on property-level rental income covering the payment, subject to lender guidelines.
Does borrowing on a HELOC change what I qualify for on the new loan?
It does not. The line supplies cash for the down payment, but the purchase loan keeps its own down payment, reserve, and source-of-funds rules. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Can I use more than one HELOC?
Up to three. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage structure and $750,000 on the longer-runway one. A borrower with more than 15 financed properties is not eligible.
