The Quick Read: An investment property HELOC is a revolving line secured by a rental you already own, and it works as a down-payment source rather than a purchase loan: you open the line on rental one, draw cash, and use it toward the next property, which still needs its own separate loan approval. The line supplies cash only. The second loan decides whether the new rental gets financed.
- On an investment property, the network ceiling is 70% CLTV (combined loan-to-value), with a $500,000 maximum line and a 700 minimum credit profile, subject to lender guidelines.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on the line.
- At least 75% of the line is drawn at closing, and pricing floats for the life of the line, so size it to the cash you actually need.
- The next rental is financed separately, with its own leverage rules and down payment.
- Lendmire arranges these lines through select wholesale partners and is not the lender. Equity-line availability covers 16 full-service states, narrower than the DSCR footprint.
What an Investment Property HELOC Actually Is
A HELOC is a home equity line of credit. It is a credit line secured by a property, with a limit you can borrow against as needed. On an investment property, the collateral is a rental, not your residence.
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.
Rental Real Estate describes two paths for investors: a line secured by your primary home, or a line secured by the rental itself. This article covers the second path. The risk follows the collateral, so a line on the rental puts that rental behind the debt, even if the cash buys a different property.
Many investors confuse this product with a DSCR loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC is underwritten mainly on you and the equity in the collateral. Credit, debt-to-income, and combined leverage drive the decision.

How Underwriting Treats the Line, Step by Step
Here is the sequence from owning rental one to closing on rental two. The line comes first because the purchase lender needs to see the cash.
1. You own the rental. The line attaches to a property you already hold, not the one you want to buy. It can sit in first or second lien position. On most rentals with a mortgage, it sits behind the existing loan.
2. The line is underwritten on you and the collateral. The lender checks credit, debt-to-income, and the equity left after your first mortgage. On an investment property, the network wants a 700 minimum credit profile. Debt-to-income can reach 50% at most, and the test uses the interest-only payment calculated on the full line, not just what you plan to draw.
3. The value is established. Because an investment line tops out at $500,000, the file ordinarily runs an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you can ask for a full appraisal if you think an automated number will miss a recent rehab.
4. The line closes and most of it funds. At least 75% of the line is drawn at closing. Afterward, additional draws start at $1,000 each in most places. This catches investors off guard, because a plan to draw only what you need does not work well on this structure.
5. You move the cash. Park the draw in your own account, ideally one used only for the acquisition. The purchase lender will want to see where the down payment came from.
6. The purchase loan is a second, separate approval. The new rental is financed on its own terms. The purchase lender decides whether borrowed funds count toward the down payment, closing costs, or reserves, and how they must be documented.
7. You carry both and then pay down. The line floats on pricing and never converts to fixed. You repay from rental cash flow, a later refinance, or other funds.
Sizing the Line: The CLTV Picture
CLTV adds the first mortgage and the line together, then divides by the rental’s value. On an investment property, the cap is 70% CLTV.
Run it with percentages. Say rental one has a first mortgage equal to 45% of its value. A 70% CLTV cap leaves 25 points of value for the line. If the first mortgage is 60% of value, only 10 points remain.
Two limits apply at once. The CLTV cap sets the room, and the $500,000 line maximum sets the ceiling, so a large, low-leverage rental is limited by the dollar cap rather than the percentage.
Market guides run higher than this. Rental Real Estate reports typical investment HELOC maximums of 70% to 80% CLTV across the broader market. On an investment property through Lendmire’s wholesale network, the ceiling is 70% CLTV.
The investment table has two credit tiers, 720 and 700, and both reach 70% CLTV. Credit above 700 therefore does not buy more leverage here, and the 700 floor is the number that matters. Skip this line if your credit sits below 700, since that is a hard floor on investment collateral.
The Second Approval: Where the Next Rental Gets Financed
The line supplies the cash, and the purchase loan buys the property. Each has its own collateral and its own test.
| Factor | Line on Rental One | Purchase Loan on Rental Two |
|---|---|---|
| Collateral | Rental you already own | The rental you are buying |
| Main test | Credit, DTI, combined leverage | Rent coverage, credit, leverage |
| Pays for | Cash you draw | The property |
| Payment type | Interest-only, then amortizing | Per loan structure |
On a DSCR purchase, most files land at 75%-80% LTV, which means 20%-25% down. Select high-leverage programs reach 85% LTV (15% down) with roughly a 700+ score, and these are purchase-loan figures, separate from the 70% CLTV ceiling on the investment line. Most programs want around 660 credit, though a 620 floor exists in parts of the network. Strong files at 700+ reach the best leverage tiers.
The coverage test compares rent to PITIA, which is principal, interest, taxes, insurance, and any association dues. A 1.00 ratio is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Reserves are the other piece. They vary by lender, leverage, loan size, and transaction type, and they commonly run around 6 months of PITIA. Conservative files at modest leverage under $1,500,000 can see reserves waived, while larger loans typically step up to about 9 months. Borrowed reserves are a question for the purchase lender, so ask before you draw.
The cash you pull out of rental one becomes debt, so total leverage across both properties runs much higher than the purchase LTV suggests. An investor in a BiggerPockets thread described using a line on a first rental as part of the down payment on the latest acquisition. The same thread notes a lender asking for two months of seasoning on HELOC funds. Seasoning is the period funds must sit in your account before a lender treats them as yours.
Structures and Variations
Several variables change how this plays out:
- Draw and repayment. On an investment property, the line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats across both periods.
- Lien position. The line can be a first or second lien, so it works whether or not rental one carries a mortgage.
- Collateral choice. A line on your primary home may carry different terms than one on a rental, so compare both when you have the equity in each.
- A DSCR cash-out as a substitute. A DSCR cash-out refinance tops out around 75% LTV on a standard long-term rental, and 70% on short-term-rental collateral. Seasoning of about 6 months is the common expectation. A cash-out also pays off and replaces your first mortgage, while a line leaves it in place. Lendmire’s comparison of an investment HELOC and a DSCR cash-out on the same rental covers that choice in depth.
Where the General Rule Breaks
The mechanics above hold for a typical single-family rental held personally. These cases change the answer.
LLC-owned rentals. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this line. This is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead, with LLC eligibility subject to lender program eligibility.
Property type. 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 agriculturally zoned properties are not offered.
Listed or recently listed. A property listed for sale, or listed within the past 60 days, is ineligible in several states. If you are weighing a sale, resolve that before applying.
Portfolio size. You can hold at most three lines. A borrower with more than 15 financed properties is not eligible. Large portfolios may find the DSCR route a better fit.
Credit events. 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.
Credit report. The report cannot be more than 90 days old at closing, and there are no rescores.
Geography. The equity-line product is available in Lendmire’s 16 full-service states only. Ask early whether your property’s state is covered.
Short-term rentals. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Stress-Testing Two Properties at Once
A line on rental one and a mortgage on rental two means two payments that both depend on tenants. Run the stress test before you draw.
Start with the line. Its pricing floats and never converts to fixed, so its cost can move after closing. Because the structure is interest-only for the first five years, the balance does not shrink on its own during the draw period.
Next, check rental one’s vacancy. It carries a first mortgage and the line. If it sits empty, you owe both payments from other funds.
Then check rental two. DSCR compares rent to PITIA only. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Finally, consider the whole portfolio. A comfortable ratio on each deal can still leave thin margins once the line is added. If one vacancy would strain you, draw less or wait.
Repeating the Move for Rental Three
Equity is tied to each property. You cannot pool equity from several rentals into one line, so each line sits on its own collateral. Because you can hold three lines, the repeat move has a built-in ceiling.
Paying the line down restores room only as far as the product allows.
If rentals are going into LLCs, plan the order. Pull the line while the property is still in your name, then handle entity transfers with the purchase lender in mind.
When to Skip It
Skip the line if the rental is held in an LLC and you do not want to re-title it. Skip it if your credit sits below 700, since that is a hard floor on investment collateral.
Skip it if you would rather not own a floating-price, interest-only balance that you must carry alongside a new mortgage. In that case, a DSCR cash-out or a larger down payment on a standard purchase may fit better.
A larger down payment lowers the monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Vesting: The legal form in which you hold title, such as individual, trust, or LLC.
Frequently Asked Questions
Can I use a HELOC on one rental for the down payment on another?
Yes, in many cases, but the purchase lender makes the final call on borrowed funds. Some lenders accept them as down payment, others want seasoning or a paper trail. Ask the purchase lender how it treats a line draw before you open the line.
Should the line be open before I make an offer?
Yes. The line is its own approval, and the purchase loan is a second one. Opening the line first lets you know your cash before you commit to a contract. A line approval does not guarantee the purchase loan, so plan for both.
Can I open the line on a rental held in an LLC?
Not on this product. Title has to sit with you as an individual or in a revocable living trust. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out is the better fit.
How much can I borrow against a rental?
On an investment property, the ceiling is 70% CLTV with a $500,000 maximum line, and the lower of the two limits controls. Your first mortgage balance, credit profile, and valuation all feed into the final amount, subject to lender guidelines.
Does passing a 1.00 DSCR on the new rental mean it will cash flow?
No. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it, and the line payment on rental one is a separate cost to carry.
