The Quick Read: The best program is the one that matches which property holds the equity, how that property is titled, and how much combined leverage the lender allows, so on an investment property line the realistic path is a 700-plus credit profile, a 70% combined loan-to-value ceiling, and a line capped at $500,000. Lendmire is a mortgage broker, not a lender. It shops this scenario across select wholesale lenders in its network. Every figure below is subject to lender guidelines and full file review.
- A line on a rental you own and a line on your own home are two different products with different ceilings.
- On an investment property, the network ceiling is 70% combined loan-to-value, and the credit floor is 700.
- LLC-titled rentals cannot hold this kind of line. Individual or revocable-trust title only.
- A HELOC does not buy the next rental. It supplies the cash, and a separate purchase loan does the buying.
What an Investment Property HELOC Actually Is
An investment property HELOC is a revolving credit line secured by real estate you use as a rental, or by a home you use to fund a rental. You borrow against equity, repay, and borrow again within a limit. The phrase covers two different products, and mixing them up causes most of the confusion.
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.
A home equity line of credit is open-end credit that lets you borrow against your equity repeatedly. Open-end means the account stays available as you pay it down. That is the opposite of a purchase mortgage, which is a one-time loan for a fixed amount.
The two products look like this:
1. A line on your primary home, used for a rental purchase. The collateral is your residence.
2. A line on a rental you already own. The collateral is the rental, usually in first or second lien position.
NerdWallet notes that a line on an investment property is harder to get than one on a primary home. Lenders see higher default risk, because a borrower in trouble tends to pay the bills on their own home first. Fewer lenders write rental-collateral lines at all.
Key Terms Defined
CLTV (combined loan-to-value): All liens on the property plus the full line limit, divided by the property’s value. The full limit counts, not just the amount you have drawn.
Lien position: Your place in line for repayment. A first lien gets paid first. A second lien sits behind it.
Draw period: The stretch when you can borrow from the line and pay interest only.
Repayment period: The stretch after the draw period, when the balance amortizes and you can no longer borrow.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly obligation, meaning principal, interest, taxes, insurance, and any association dues.
Vesting: How title to the property is held, such as in your own name, a trust, or an LLC.
How Underwriting Treats the Line, Step by Step
On this network, an investment line is underwritten mostly on you, the borrower, and on the equity in the property. Here is the sequence a wholesale lender follows.
Step 1: Equity is measured. The formula is value times the maximum CLTV, minus existing liens. On an investment property across this network, the maximum is 70% CLTV. That holds at a 720 credit profile and at a 700 profile, so credit above 700 buys eligibility rather than extra leverage.
Run the logic in percentages. Say the first mortgage sits at 50% of value. The 70% ceiling leaves room for a line worth up to 20% of value. If the first mortgage is already near 65% of value, there is almost no usable line. A big equity pool and a usable line are not the same thing.
Step 2: The line is sized. Lines on this network start at $25,000, and a line above $500,000 is reserved for primary residences. On a rental, the CLTV ceiling is the limit to check first, because it often sets the line size before any dollar cap does.
Step 3: The borrower is qualified. The debt-to-income ceiling is 50%, and a ratio above 45% requires a 680 minimum. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Credit scores come from a single-bureau model and the report cannot be older than 90 days at closing.
Step 4: The property is valued. Full appraisals are required only on lines above $500,000, so an investment line runs through an automated valuation and commonly closes with no traditional appraisal. A higher CLTV may require a secondary valuation, and a full appraisal is available if you request one.
Step 5: Documents and title are checked. Expect leases or rent information, proof of insurance, and a clean title review. Title must sit in your individual name or in a revocable living trust.
Step 6: Draw structure is set. Investment lines run one structure only: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed.
That 75% draw requirement matters. You cannot open a large line “just in case” and leave it untouched. Most of the line is borrowed from day one, and you pay interest on it from that point. After closing, each later draw has a $1,000 minimum.
The Fork: Home Line, Rental Line, or Cash-Out
The three routes to the same cash behave very differently. A short comparison helps.
| Factor | Line on Primary Home | Line on Rental | DSCR Cash-Out |
|---|---|---|---|
| Collateral | Your residence | The rental | The rental |
| Max leverage | Up to 90% CLTV, only at 720+ | 70% CLTV | About 75% LTV |
| Credit floor | 600 program floor | 700 | Varies; 620 to 700+ |
| Title | Individual or revocable trust | Individual or revocable trust | LLC possible* |
| Existing first mortgage | Stays | Stays | Replaced |
*Subject to lender program eligibility.
A few notes on the table. The 90% figure is a top-tier primary-residence ceiling that applies only at a 720-or-better credit profile.
Which Path Fits Which Investor
The structure that fits depends on your situation. Here is how it breaks down across the wholesale lenders Lendmire works with.
You own a rental in your own name or a revocable trust, with a 700-plus profile and a low first mortgage. The rental line is the cleanest fit. Your home stays out of it.
You have large equity in your home and a modest rental balance. A primary-home line can reach higher leverage, but your residence becomes the collateral for a rental purchase. Investors on BiggerPockets pose this as a plain question: are you willing to put your own home at risk?
Your rental sits in an LLC. A standard line will not work, because LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Your choices are a vesting change or a cash-out refinance. This is the sharpest structural difference from a DSCR loan.
Your credit sits below 700. The investment line is not available at that level, even though the program floor elsewhere is 600. A DSCR cash-out may fit better, since credit tiers there can start lower.
You own many financed properties. A borrower can carry up to three lines, and anyone with more than 15 financed properties is not eligible.
The property type is unusual. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered. A property listed for sale, or listed within the past 60 days, is ineligible in some states.
Using the Line to Buy the Next Rental
The line is not a purchase mortgage. It is the source of cash. Then a separate loan buys the property, and that is where DSCR financing comes in.
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. A DSCR purchase is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. For a deeper walkthrough, the complete DSCR loans guide covers the full mechanics.
Typical purchase terms on the network look like this:
- Most files land at 75%–80% LTV on a purchase, which means 20%–25% down.
- Select programs reach 85% LTV on a purchase with roughly a 700-plus score.
- A coverage ratio of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
- Reserves vary by lender, leverage, and loan size. Around six months of PITIA is common. PITIA is principal, interest, taxes, insurance, and association dues.
The line funds your down payment. A broker on BiggerPockets says a HELOC-sourced down payment is almost always permissible. The purchase lender still documents where the money came from, and how borrowed funds are treated varies by lender.
Here is where the two tests meet. The strongest files clear both: enough equity to open the line, and enough rental coverage on the new property. A bigger down payment lowers the new loan’s payment and can lift its DSCR. It does not erase leverage caps, credit floors, reserve rules, or property eligibility.
The Cash Flow Trap Nobody Mentions
Clearing a coverage ratio of 1.00 is not positive cash flow. DSCR compares rent to PITIA and nothing else. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Now layer the line on top. The new rental’s rent has to carry its own mortgage, and your portfolio has to carry the line payment. Those are two separate obligations, even though only one shows up in the DSCR.
Three pressures stack up:
1. The pricing floats. The line never converts to fixed, so its cost can move at any point in the draw or repayment period.
2. Most of the line is drawn at closing. You carry interest on borrowed money whether or not you use it.
3. The repayment period arrives. After five interest-only years, the balance amortizes over 25 years, and the payment steps up.
There is also a line-reduction risk. The CFPB’s HELOC booklet says a lender may reduce your credit line if your home’s value falls. Do not treat a line as guaranteed liquidity.
Run a stress test before drawing. Ask what happens if the new property sits vacant for a stretch and the line’s cost rises at the same time. If the answer is uncomfortable, size the draw smaller.
Where the General Rule Breaks
A few cases do not follow the standard script.
Market surveys versus this network. NerdWallet reports that investment HELOC lenders commonly look for a 720 score, up to 80% LTV, about six months of reserves, and 20% equity left over. Those figures describe the broader market. On this network, an investment line tops out at 70% CLTV with a 700 minimum, and no tier sits above that.
Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. On investment files, a foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure, or short sale needs four.
Tight equity after a recent purchase. If you bought the rental recently, your first lien is probably near its starting balance, which leaves little room under a 70% ceiling.
State differences. Some states apply a CLTV cap that depends on credit profile, and a few restrict listed properties. Lines are also available only in 16 full-service states, which is narrower than the 41-market DSCR footprint, Washington, D.C. included.
No-ratio and sub-1.00 DSCR. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
Using the Line as Bridge Capital
Many investors use a line as bridge capital rather than a permanent loan. The sequence runs like this: draw, buy, stabilize, refinance into a long-term loan, repay the line, repeat.
The constraint on this network is that the line is a standalone loan with a five-year draw and a mostly drawn balance. That makes it a poor fit for investors who need to open a line and leave it idle. It suits those who have a purchase lined up.
When the line is the wrong tool, the alternative is replacing the first mortgage. A DSCR cash-out refinance does that, and the lender evaluates the property’s rent against the new payment.
A Decision Checklist
Before you apply, work through these questions.
1. Where does your equity sit? Rental, primary home, or both.
2. How is the rental titled? Individual or revocable trust works. An LLC does not.
3. What is your credit profile? 700 is a hard floor for an investment line.
4. How much of the 70% ceiling is already used? Subtract your first lien from 70% of value.
5. Will the next rental clear its own coverage test? The line payment is separate.
6. Can you carry the line if rent stops? That tells you your draw size.
7. Would a cash-out refinance serve you better? Especially if title is in an LLC or the equity is large.
Frequently Asked Questions
Can I get a HELOC on a rental property?
Yes, if the rental is in your name or a revocable trust and your credit profile is 700 or better. On this network, the line tops out at 70% combined loan-to-value and $500,000. Eligible property types are single-family, 2-4 units, PUDs, townhomes, and condos. Approval is subject to lender guidelines and full file review.
Can a HELOC cover the down payment on another rental?
Generally yes. The purchase lender documents the source of the funds, and treatment of borrowed funds varies by lender. The line does not replace a purchase loan.
Does the HELOC payment count against my DSCR on the next property?
A DSCR loan is reviewed primarily on the new property’s rent covering its own payment, so the line payment is not part of that ratio. It is still a real monthly cost. Investors on BiggerPockets note the line’s minimum payment can enter debt-to-income calculations on loans that use personal income.
My rental is in an LLC. What are my options?
A standard line cannot be placed on LLC-held title, because LLCs and several trust types cannot hold title on these lines. You can move title to your own name or a revocable trust, or you can use a DSCR cash-out refinance. LLC borrowers are eligible on DSCR files subject to lender program eligibility.
How many lines can I hold at once?
Up to three lines per borrower, with combined exposure capped by the program. A borrower who owns more than 15 financed properties is not eligible.
