The Quick Read: A HELOC can fund a down payment on an investment property, but the purchase lender decides whether the draw counts, and the line has to fit its own limits: in Lendmire’s network an investment-property line tops out at 70% CLTV and $500,000, with a 700 minimum credit score. The line is underwritten on you and your equity. The new rental loan is underwritten on the rent. Both approvals have to work at the same time.
Key takeaways
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 line can sit on a rental you own or on your primary home. The collateral you pick decides what is at risk.
- On an investment property, the network ceiling is 70% CLTV, and credit above 700 buys eligibility rather than extra leverage.
- A DSCR purchase loan treats the HELOC draw as borrowed funds. Disclose it and let the purchase lender confirm it is acceptable.
- Clearing 1.00 on the new property does not mean the HELOC payment is covered. That payment comes from your other cash flow.
- Investment-property lines are not an LLC product. Title has to sit with an individual or a revocable trust.
What Is an Investment Property HELOC, Really?
A HELOC is an open-end line of credit secured by property. You draw against equity, repay, and can often draw again during the draw period. Equity is the value of the property minus what you owe on it.
An investment-property HELOC puts that line on a rental you own. It is a different product from a line on your own home. NerdWallet’s explainer on investment-property HELOCs notes that fewer lenders offer them and that borrowers usually can’t pull as much as they could from a primary residence. Bankrate’s overview makes a similar point about availability and cost.
Lendmire does not lend. It brokers these lines through select wholesale partners. The investment-property line in that network is available in 16 full-service states, which is narrower than the 41-market DSCR footprint (40 states plus Washington, D.C.) Every figure below is subject to lender guidelines and full file review.
Which Property Secures the Line?
The collateral choice is the first decision, and it changes the risk. A line on your primary home puts your home behind the down payment. A line on an existing rental puts that rental behind it.
| Factor | Line on primary home | Line on existing rental |
|---|---|---|
| Collateral at risk | Your residence | The rental |
| Ceiling in this network | Up to 90% CLTV, only at 720+ | 70% CLTV |
| Minimum credit | 600 program floor | 700 |
| Max line | Up to $750,000 | $500,000 |
| Title | Individual or revocable trust | Individual or revocable trust |
Two cautions on the table. First, the 90% figure applies only to primary-residence and second-home lines at a 720-or-better profile. It never applies to a rental. Second, the primary-home path has a hidden cost: you are using the roof over your head to buy a rental.
On this network, the investment-property ceiling is 70% CLTV, and there is no tier above it.
How Does Underwriting Treat the Line? (Step by Step)
Underwriting the line comes first, and it looks at you, not the rent. Here is the sequence on an investment-property line in this network.
1. Size the equity. Take the property value, multiply by 70%, and subtract every lien already on the property. What remains is the most the line can be. A rental worth 100 units with a first lien at 40 units leaves room for a line of up to 30 units. Percentages keep the arithmetic honest. The calculator handles the dollars.
2. Check credit. The floor on an investment line is 700. A 720 score reaches the same 70% CLTV, so higher credit adds eligibility, not leverage. The score is a single-bureau model keyed to the primary wage earner.
3. Check debt-to-income. The ceiling is 50%. A ratio above 45% requires a 680 minimum, which an investment line already clears. The line is qualified on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.
4. Value the property. Investment lines top out at $500,000, and full appraisals begin only above $500,000. So an investment line is structurally in the automated-valuation lane and commonly closes with no traditional appraisal. A borrower can still request a full appraisal.
5. Confirm title and property type. Title must be held by an individual or a revocable living trust. Single-family, 2-4 units, PUDs, townhomes and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not offered.
6. Check exposure. A borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible.
Draw Structure: What You Are Signing Up For
Investment lines run one structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats during the draw and the repayment period, and it never converts to fixed.
That last point shapes how the line works as a down-payment tool. Because most of the line is drawn at closing, it behaves more like a loan than a standby reserve. Interest accrues on most of it from the start. The minimum line is $25,000.
When the draw period ends, principal starts amortizing. The payment steps up, and it can step up again if the index moves. Any plan that depends on the line staying small and cheap has to survive that step.
The CFPB’s explanation of a HELOC is blunt on one point. If you fall behind on the line, you could lose the property securing it. That is as true for a rental as for a home. Lenders can also freeze or reduce a line if values fall, and a sale of the secured property generally requires paying the line off.
Does the Purchase Lender Accept HELOC Money as a Down Payment?
It depends on the purchase lender and the program, and the answer is not uniform. Treat the HELOC draw as borrowed funds, disclose it, and ask before you write an offer.
Investor commentary is split. A mortgage broker in a BiggerPockets thread on using a HELOC as a down payment calls a primary-residence HELOC almost always permissible as a source of down payment funds. An investor in another BiggerPockets thread says the question of whether any funds are borrowed has appeared on every mortgage application he has filled out. Both can be true, because different programs have different rules.
DSCR purchase loans are not agency products, so each program sets its own source-of-funds rules. Across the wholesale network Lendmire places files with, a documented line draw is commonly reviewable, while an undisclosed one is a problem on any file. The paper trail that clears most reviews looks like this:
- The HELOC statement showing the balance and the draw.
- The transfer confirmation into your checking account.
- The checking statement showing the deposit.
- A fully signed purchase contract that matches the amounts.
Parking the money in your account for a while does not change what you have to disclose. Disclose the source as it is.
How Does the New Purchase Loan Treat the Line?
The purchase loan is a separate approval. It has its own leverage tier, reserve rules and source-of-funds review.
On a DSCR purchase, most files in the network land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV, with roughly a 700+ score, and carry stronger reserve and credit expectations. Coverage compares rent to PITIA (principal, interest, taxes, insurance and any HOA dues). A 1.00 ratio is where select programs start, not a universal rule. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
A larger down payment lowers the new payment and can lift the ratio. It does not erase leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Two things the ratio does not do:
- It does not count the HELOC payment. That payment has to be carried from your other income.
- It does not equal positive cash flow. Repairs, vacancy, management, utilities and capex all sit outside the calculation.
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 line will still appear on your credit report as a liability. Reserves vary by lender, leverage, loan size and transaction type, commonly around 6 months of PITIA. They step up on larger loans.
Where the Rule Breaks: Named Edge Cases
The property sits in an LLC. A DSCR loan can often close in an LLC, subject to program terms. An investment-property HELOC cannot. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A rental already deeded into an LLC needs a vesting change before a line, or a DSCR cash-out refinance instead. A vesting change has its own consequences, so settle that before choosing a path.
The rental was just purchased. Thin equity after a low-down-payment purchase leaves little or nothing under a 70% CLTV ceiling. That is CLTV arithmetic, not a special rule. On the DSCR side, a cash-out refinance tops out around 75% LTV, and about 6 months of seasoning is the common expectation. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The property is listed. A property listed for sale, or recently listed, is ineligible in several of the states where the line is offered.
Collateral type. Manufactured homes, log homes and barndominiums are not offered, either for the HELOC or in the network’s DSCR programs.
Heavy combined leverage. An investor in the same BiggerPockets thread flags the concern that a line funding the whole down payment leaves the property with almost no equity cushion behind the combined debt. The wholesale lender reviewing the purchase will run that math too.
Planning to move in. If the plan is to convert a home to a rental later, read the line’s terms on occupancy and rental use before borrowing.
Is a HELOC the Right Tool, or Is a DSCR Cash-Out Better?
The alternatives differ on collateral, structure and what gets underwritten.
| Option | Underwritten on | Best for | Watch out for |
|---|---|---|---|
| HELOC on rental | Borrower and equity | Holders with equity and strong credit | 70% CLTV cap, floating payment |
| HELOC on home | Borrower and equity | Owners who accept home risk | Home is the collateral |
| DSCR cash-out | Rent vs. PITIA | Rental equity in an LLC | Seasoning, about 75% LTV ceiling |
| Savings or partners | Not applicable | Avoiding new debt | Slower scaling |
A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That path may fit an investor whose rentals sit in an LLC, or one who wants a fixed structure. The spine of the DSCR product is a 30-year fixed term. Extended terms, such as 40-year, and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. Loans above $2,500,000 generally stay with 30-year fixed structures.

Stress Test Before You Sign
The line fails investors in three predictable ways.
- Vacancy. Rent on the new property covers that property’s own payment. The HELOC payment has to come from somewhere else, so vacancy risk concentrates there. An investor quoted by Benzinga says he kept a close watch on cash for HELOC payments even when rental income fluctuated.
- Pricing drift. The payment floats with the index. Model it moving the wrong way.
- End of the draw period. After the 5-year draw, principal starts amortizing, and the payment steps up.
Then there is recycling. A line is finite even though it revolves. One investor on a BiggerPockets thread about HELOC-funded down payments doubts it will carry another 5 to 10 deals. The three-line cap and the 15-property limit set the ceiling on the network side.
The usual exit is to buy, stabilize, refinance and repay the line from the proceeds. That plan works only if the refinance qualifies when the time comes. 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.
Key Terms Defined
CLTV: Combined loan-to-value, meaning all liens on a property added together and divided by its value.
Draw period: The stretch when you can borrow against the line, typically paying interest only.
Source of funds: The documented origin of the money used for a down payment.
DSCR: Debt service coverage ratio, meaning monthly rent divided by the monthly PITIA on the property.
Vesting: How title is held, such as an individual, a revocable trust or an LLC.
Frequently Asked Questions
Can I use a HELOC on my primary home for a rental down payment?
Often yes, but the purchase lender decides. The line has to be disclosed as borrowed funds, and the home becomes collateral for the down payment. In the network, a primary-home line reaches higher CLTV than a rental line, but only at a 720-or-better profile.
What is the maximum HELOC on an investment property?
In Lendmire’s network, an investment-property line caps at 70% CLTV and $500,000, with a 700 minimum credit score. The minimum line is $25,000. There is no higher tier for investment properties.
Can an LLC take out an investment-property HELOC?
No. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Does a HELOC payment count in my DSCR?
No. The ratio compares the new property’s rent to its own PITIA. The HELOC payment still has to be carried from other income, and the line shows up on your credit report.
Do I need an appraisal for the line?
Usually not on an investment line. Because lines cap at $500,000, they commonly run automated valuation. A higher CLTV may require a secondary valuation, and a borrower can request a full appraisal.
