The Quick Read: An investment property HELOC is a revolving line of credit secured by a rental you already own. You draw cash from the line to fund the down payment or the full price of the next property. A separate long-term loan, often a DSCR loan, then replaces the borrowed money.
- On the wholesale network Lendmire works with, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000, subject to lender guidelines.
- The line is underwritten on you and the collateral, not on the property you are buying.
- Title must sit with you or your revocable living trust. An LLC cannot hold it.
- The exit loan is a second approval, and the line’s payment never enters the new property’s DSCR.
The equity stays tied up as collateral until the line is paid down.
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.
How Does an Investment Property HELOC Work to Buy Another Rental?
An investment property HELOC works in three moves: a lender approves a line against equity in a rental you own, you draw cash from it to buy another property, and you repay it with long-term financing or a sale. The line sits beside your first mortgage instead of replacing it.
Two products get called an investment property HELOC, and the difference matters. The first is a line on your primary home, with the cash used to buy a rental. The second is a line secured by a rental you already own. This article focuses on the second, with a short contrast to the first later on.
NerdWallet notes that a line on a rental is possible, but the lender pool is smaller and the requirements are stricter than on a primary home. Multiple appraisals may be required. Bankrate adds that lenders weigh both your credit and the property’s financials. Lenders treat rentals as riskier collateral, which is why fewer of them offer the product.
Experian describes the line as a way to tap equity without refinancing the first mortgage. That is the key difference from a cash-out refinance, and it is the reason some investors with a low locked-in first mortgage prefer a line.
How Is the Line Underwritten, Step by Step?
The lender looks at the property that secures the line, not the one you plan to buy. It checks your equity, your credit, your debt-to-income ratio (DTI, meaning monthly debts divided by monthly income), and the collateral itself. The target property’s rent does not decide the line.
Here is the sequence, using the guidelines across our wholesale network.
1. Check the equity. The lender adds your first mortgage balance to the new line and divides by the property’s value. That ratio is CLTV. On an investment property in this network, the ceiling is 70% CLTV, and the maximum line is $500,000.
2. Check credit. Credit of 700 is a hard floor for an investment line, with no tier beneath it. A 720 score reaches the same 70% CLTV as a 700 score. Better credit above 700 buys eligibility rather than extra leverage.
3. Check DTI. The maximum is 50%. The lender reviews your file on the interest-only payment calculated on the full line, not just the amount you plan to draw.
4. Value the property. Because an investment line caps at $500,000, and full appraisals are required only above that size, these lines commonly run on an automated valuation with no traditional appraisal. You can still request a full appraisal.
5. Verify title and property type. More on both below.
6. Close and draw. At least 75% of the line is drawn at closing. That detail changes how investors can use the product, covered in the next section.
Here is a simple picture of the equity math. Say your rental’s first mortgage equals 45% of its value. With a 70% CLTV ceiling, the new line can use the remaining 25% of value. If the property you want to buy is similar in value, that 25% roughly matches a 25% down payment. Closing costs and repairs sit on top. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The $500,000 cap is a separate limit. A high-value rental can hit the dollar cap before it hits the percentage cap.
Credit reports must be no more than 90 days old at closing, and there are no rescores. Every figure here is subject to lender guidelines and full file review. None of it is a commitment to lend.
Can You Open the Line First and Leave It Undrawn?
On this network, not fully. Many investors like to open a line and leave it untouched until a deal appears, which lets them make an offer with no financing contingency. But at least 75% of an investment line is drawn at closing, and interest begins on that drawn balance right away.
That changes the plan. You size the line to the purchase you have in mind, not to the largest number you can get. You also carry interest on most of the line from day one, whether or not a deal is under contract.
The better workflow is to line up a target property and the exit loan conversation before you open the line. Move the draw into a dedicated account so the money’s path is clear. If part of the draw goes to personal use, keep it separate from the part that buys the rental.
Investment lines in this network run a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and pricing floats across both periods.
What Does the Payment Look Like Over Time?
During the draw period, payments are interest-only and the balance stays flat. When repayment starts, principal joins the payment and it steps up. Because pricing floats, the payment can also change in either phase.
The Consumer Financial Protection Bureau’s HELOC booklet explains the mechanics. Most HELOCs carry variable pricing tied to a public index, and the payment can change as the index moves. The booklet is older, so use it for how the product works, not for current numbers.
Stress-test two moments before you commit. First, test the payment if the index rises during your hold. Second, test the payment on the day repayment begins. The line’s payment is a second obligation on top of the first mortgage and the financing on the new property. A deal that covers its own debt can still strain your overall cash flow once the line is added.
What Is the Exit Plan?
The line is a bridge, and the exit loan is what makes it one. You repay the line with long-term financing on the new property or with proceeds from a sale. The usual exits are a DSCR purchase loan at closing or a DSCR cash-out refinance after you buy with cash.
A DSCR loan is an investment loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR means debt service coverage ratio: monthly rent divided by the full monthly payment (principal, interest, taxes, insurance, and any HOA dues). The complete DSCR loans guide covers the full mechanics.
Here is how the exit loans typically look across the network.
- Purchase: Most files land at 75% to 80% LTV, meaning 20% to 25% down. Select high-leverage programs reach 85% LTV (15% down) with roughly a 700-plus score.
- Cash-out refinance: Most programs top out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Credit: A 620 floor exists in parts of the network. Most programs want around 660, and 700 or higher unlocks the strongest leverage.
- Reserves: They vary by lender, leverage, loan size, and transaction type. About 6 months of PITIA (principal, interest, taxes, insurance, and association dues) is common.
Two details matter most for a HELOC investor. First, the line and the exit loan are two separate approvals. Getting the first does not secure the second. Second, in this network’s DSCR programs, the line’s payment never enters the new property’s DSCR. The ratio compares that property’s rent to that property’s own PITIA.
That separation helps the coverage number, but it does not make the deal safe. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. Your personal credit file also still shows the line.
A larger down payment lowers the new loan’s payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Where Does This Break? Edge Cases That Stop Files
The general rule is that equity plus credit gets you a line. These are the places where that rule fails.
Title. The line’s collateral must be held by you personally or by your inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan, which can often close in an LLC, subject to lender program eligibility. If your rental is already deeded to an LLC, you need a vesting change or a DSCR cash-out refinance instead.
Existing first mortgage. The line can sit in first or second lien position. If your first mortgage documents bar a junior lien, a first-position cash-out refinance is the alternative.
Property type. Eligible collateral includes single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Recent listing. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.
Exposure. A borrower is limited to three lines. Combined exposure caps at $750,000 or $2,000,000, depending on the wholesale program. A borrower with more than 15 financed properties is not eligible.
Geography. Home equity lines run through Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.
Mixed use of funds. If part of the draw goes to the rental and part goes elsewhere, the two uses should be tracked separately.
Rental Collateral or Your Home? The Two-Scenario Contrast
The collateral choice decides who carries the risk. A line on your primary home puts your residence behind the loan. A line on a rental puts that rental behind it. Bankrate and NerdWallet both note that foreclosure risk attaches to whatever property secures the line.
Primary-residence lines are sized under separate terms and can be larger than investment lines. That can look attractive if your rentals carry thin equity. The tradeoff is putting your own home on the line for a business purchase. Many investors accept that risk. Others prefer to keep the downside inside the rental portfolio. Neither choice is wrong, but it should be a deliberate choice.
Investment lines also come with a tighter set of limits than primary lines: a 700 credit floor, the 70% CLTV ceiling, and the $500,000 cap. If those limits are too tight for your plan, the other tools below may fit better.
How Does a HELOC Compare With Other Ways to Fund the Purchase?
Each path has a different underwriting basis. A HELOC leans on you and your equity. A DSCR loan leans on the property’s rent. The right choice depends on which of those you have more of.
| Path | Underwritten on | First mortgage | Title |
|---|---|---|---|
| Investment HELOC | Credit, DTI, equity | Stays in place | You or revocable trust |
| DSCR cash-out refinance | Rent coverage, equity | Replaced | Often LLC-eligible |
| DSCR purchase loan | Rent coverage, down payment | New loan | Often LLC-eligible |
| Primary-home HELOC | Credit, DTI, home equity | Stays in place | You or revocable trust |
A DSCR cash-out refinance tops out around 75% LTV on a standard rental. A short-term-rental cash-out tops out at 70%. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The cleanest rule is this. If your first mortgage has locked-in terms worth keeping, a line beside it makes sense. If you would rather replace the first mortgage and pull more equity, and the property’s rent supports it, a cash-out refinance fits.
When Does It Fit, and When Does It Not?
A HELOC-funded purchase fits when most of these are true:
- You have a rental with meaningful equity held in your name or a revocable trust.
- Your credit is at least 700 and your DTI is comfortable at the full line amount.
- The target property has a clear path to a DSCR exit, and you have already talked through its coverage.
- You can carry the line’s payment alongside the new property’s financing.
It is a poor fit when:
- Your rental sits in an LLC and you do not plan to change the vesting.
- The target property is a type the DSCR network does not offer, such as a manufactured home or log home. You would have no clean exit.
- The deal only works if rents rise, or if the exit loan comes in smaller than the line balance.
- Your first mortgage forbids a junior lien.
Some investors use the line to buy a property with cash and then refinance it after seasoning. That works when the cash-out loan, usually around 75% LTV after about 6 months of seasoning, is large enough to repay the line. If the exit comes in smaller, you cover the gap from your own cash.
A common mistake is treating the line as free money. It is a loan against real equity, and it carries a second payment.
Key Terms Defined
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line and pay interest only. On investment lines in this network it lasts 5 years.
Repayment period: The stretch after the draw ends, when principal and interest are both due. Investment lines run 25 years.
DTI (debt-to-income ratio): Your monthly debt payments divided by your monthly income.
DSCR (debt service coverage ratio): Monthly rent divided by the property’s full monthly payment. It measures rent against PITIA only.
PITIA: Principal, interest, taxes, insurance, and association dues.
Vesting: How title is held, such as in your own name, a revocable trust, or an LLC.

Frequently Asked Questions
Can a HELOC cover the entire purchase price of an investment property?
Sometimes, but only if the line is large enough. On this network an investment line is capped at 70% CLTV and $500,000, so it often covers a down payment more than a full price. Using it for a cash purchase works best when the property is modestly priced and you plan to refinance afterward.
Do I need an appraisal?
Usually not a traditional one. Because investment lines cap at $500,000, they commonly run on an automated valuation. A higher CLTV may require a secondary valuation, and you can request a full appraisal in any case. Multiple appraisals may be required at some lenders, which is one more reason to compare programs.
Does the HELOC payment count against the new property’s DSCR?
No. In this network’s DSCR programs, the ratio compares the new property’s rent to that property’s own PITIA. The line’s payment does not enter the calculation. It still affects your personal budget, and the line still appears on your credit file.
Can I get the line if my rental is in an LLC?
Not as it stands. Title must be held by you or your inter vivos revocable living trust. A property deeded to an LLC needs a vesting change before it can secure the line, or you can use a DSCR cash-out refinance instead, per lender program requirements.
What if the exit loan is smaller than the line balance?
You cover the difference from your own cash. That is why the exit plan comes before the draw. Talk through the expected DSCR purchase or cash-out terms for the target property first, and model the shortfall case, since leverage caps and coverage requirements apply to the new loan.
